Among a plurality of radio base stations, to a radio base station whose transmission delay time between a base station control device and its own station will be the longest, down data from the base station control device is transmitted to have a buffering time of zero, while to the other radio base stations, data is transmitted with a buffering time corresponding to the degree of relative shortness of a transmission delay time applied, and the buffering time is modified by monitoring a change of a difference in delay time of up data from the radio base station.

Mobile communication system, base station control device and radio base station forming the same, and communication timing control method thereof

An electrical connector having an electrical plug (102) to be plugged into an electrical receptacle (130). The electrical plug (102) includes an electrically insulative plate-like substrate and a plurality of first electrical contacts (118) formed in parallel on at least a side surface at one end of the substrate for a predetermined length from the one end. The plug further includes a shielding part (126) formed of an electrical conductor which substantially shields all of the substrate in a position nearer an end other than the one end having the electrical contacts (118). The electrical receptacle includes an electrically insulative receiving member (138) forming at least part of a recess in which the substrate of the plug is inserted. A plurality of second electrical contacts (142) are arranged in the receiving member (138) so as to contact the plurality of contacts in the plug whenever the substrate of the plug is inserted into the recess. The electrical receptacle (130) also includes a shielding electrical contact (140) formed to contact the shielding part of the electrical plug (102). The shielding electrical contact includes a liquid removing member (235) for removing liquid from the substrate during insertion into the recess. A heated air mechanism (271, 273) may be included to assist in liquid removal. The shielding may also serve the purpose of latching the plug and receptacle together and the plug may be of circular shape.

Electric connector provided with a shielding part for electrical

An image pickup unit provided with an image pickup element is of structure capable of being detachably received in an endoscope body or a TV camera. After having been used in observation, the image pickup unit is dismounted, whereby disinfection processing and sterilization processing of the endoscope body from which the image pickup unit is dismounted, or the TV camera can be executed without inviting deterioration and the like of a characteristic of the image pickup unit by a disinfection unit, a sterilization unit or the like.

Electronic type endoscope in which image pickup unit is dismounted to

An endoscope apparatus comprising an electrical connector which is electrically connected to an electrical device such as a CCD in an organism inserting device such as an endoscope which has an inserting section inserted into a organism. The electrical connector is connected to an electrical connector receptacle such as a control unit after the organism inserting device has been disinfected and sterilized by disinfection liquid. Processing is first performed in which the liquid remaining in the vicinity of an electrical contact of the electrical connector is removed by a liquid removing mechanism and, thereafter, electrical operation occurs. Thus, generation of a short-circuiting accident is prevented.

Endoscope apparatus provided with liquid removing mechanism for the

An endoscope apparatus for inspecting an object including an insertion section insertable into the object and having a distal end and a proximal end, an image guide arranged within the insertion section and having entrance and exit ends arranged at the distal and proximal ends of insertion section, respectively, an objective lens system arranged at the distal end of insertion section for forming an optical image of the object onto the entrance end of image guide, an eyepiece lens system arranged at the proximal end of insertion section for projecting the optical image transmitted through the image guide onto an observating position, a first piezo-electric bimorph arranged at the distal end of insertion section for vibrating the entrance end of image guide in a direction perpendicular to a longitudinal axis of the insertion section over a given distance, a second piezo-electric element arranged at the proximal end of insertion section for vibrating the exit end of image guide in the same direction and over the same distance as those of the entrance end of image guide, so that annoying black mesh and Moire fringe are removed.

Endoscope apparatus

A video converter can be mounted on an optical endoscope which has an image guide capable of transmitting an optical image formed by an objective optical system. The video converter incorporates a solid-state imaging device having a plurality of pixels. The levels of the outputs from the pixels of the solid-state imaging device are compared with a dark current level, and the size of the imaging area of the image guide is detected from the result of the comparison. A photo-sensing/imaging area scaling signal is selected or generated in accordance with the result of detection if the imaging area of the image guide, and the intensity of the illuminating light is controlled in accordance with the actual imaging area which is determined by incorporating the photo-sensing/imaging area scaling signal.

Light control device for endoscope

The present invention relates to an endoscope system which comprises an endoscope having a handy-control section and an insertion section adapted to be inserted into the body cavity, and a video-signal processing unit having an electric circuit capable of receiving and processing a video signal, produced by a solid-state image sensing device, through the medium of the endoscope, and of recording and/or displaying the video signal on a monitor TV. A receptacle, which is provided on the outer surface of the video-signal processing unit, includes an electrical connecting portion connected to the electric circuit in the processing unit. The endoscope system further comprises a video camera which has a solid-state image sensing device therein, and is mounted on an eyepiece portion for optical observation at the control section of the endoscope. The video camera is connected to a signal cord which has a plug connectable with the electrical connecting portion of the receptacle. Also, the video camera has remote control switches which can be used to control the video-signal processing unit through the medium of the signal cord. An operator can freely start recording or other operations by operating the remote control switches.

Endoscope system

A photoresist process which comprises a process for spin-coating a substrate with a resist, a process for transferring a mask pattern onto the coated resist film followed by exposure, and a developing process for forming a pattern on the substrate after the pattern has been exposed. When the developed pattern of the resist pulsates with the increase or decrease of parameters in the process for applying resist, the value of the parameter is set to a value that corresponds to an extreme value of the pulsation.

Method of applying a resist

A solid-state image pickup apparatus includes a body mounted on an eyepiece section and a solid-state image sensor arranged in the body and having a pickup face opposed to an objective optical system of the eyepiece section. The sensor is fixed to a base which is supported by an adjusting member to be movable in a direction parallel to the pickup face. The base is moved by adjusting centering screws so that the center of the pickup face is aligned with the optical axis of the optical system. A focusing member is supported by the body to be movable along the optical axis. The adjusting member is supported by the body and focusing member to be movable together with the focusing member along the optical axis and universally movable around the point of intersection of the pickup face and the optical axis. The adjusting member is universally moved by tilting screws to adjust the tilt of the pickup face relative to the optical axis.
