A self-running vacuum cleaner comprises a homing mode of following a back of a user with receiving a signal from a light emitting means or a transmitting means of a position indicator means held by the user, an instruction operation mode, in which the user instructs a cleaning area to the self-running vacuum cleaner, and an execution mode for cleaning up the cleaning area instructed. When the self-running vacuum cleaner operates under the homing mode or the instruction mode, a signal from the light-emitting means or the transmitting means is received by a receiver means attached on a periphery portion of a measuring means, which is provided in an upper portion of the vacuum cleaner. Comparing the signals from the two (2) receiver means in strength thereof determines the distance and the direction from the position indicated by the light-emitting means or the transmitting means up to the vacuum cleaner.

There is provided an operating instrument insertion apparatus capable of easily inserting an operating instrument into the tissue. The operating instrument insertion apparatus includes a hollow tubular member for receiving an operating instrument therein, and a plurality of scoop-like members provided at a distal end of the hollow tubular member. The plurality of scoop-like members can be opened in such a manner that distal ends of the scoop-like members are moved away from each other in a direction transverse to an axial direction of said hollow tubular member, and the plurality of scoop-like members can be closed in such a manner that the distal ends of the scoop-like members are moved toward each other in this transverse direction, wherein the scoop-shape members in the opened condition cooperate so that an outside diameter formed thereby is no greater than an outside diameter of the hollow tube member.

Operating instrument insertion apparatus and operation supporting apparatus

A walking aid apparatus including a movable body and a support unit provided to the movable body to support a user further includes means for reducing a change rate of speed of the movable body with respect to a change in a force applied from the user to the support unit. With this arrangement, even when the user stumbles and applies a strong force to the support unit, the movable body can be prevented from moving suddenly, minimizing the possibility of the user being left behind the movable body.

A surgical operating apparatus which reduces an adverse influence caused by a diseased portion of a patient while a surgical operation is carried out by the surgical operating apparatus. The surgical operating apparatus includes a disease portion tissue manipulator for treating a treating subject portion of the patient in response to an entered control command, a manipulation inputting unit for inputting a manipulation command to the disease portion manipulating means, and a detector for detecting a repeated movement of a diseased portion of said patient. The surgical operating apparatus adjusts the movement of the disease portion manipulator in response to the detection output from the detector.

Surgical operating apparatus

A surgical apparatus for automatically and dynamically changing the constitution of a system and the operation of respective elements. The surgical apparatus includes a plurality of devices respectively, a supervisory controller having a transmission path among the plurality of devices for supervisorily controlling the devices and an operational procedure description store for storing an operational procedure description describing operational procedures of the plurality of devices in which the supervisory controller includes a detector for detecting constitutions of the devices and for transmitting the operational procedure description necessary for the devices detected by the detector to the respective devices via the transmission path.

Surgical apparatus

A magnetic recorder in which magnetic signals are transmitted between a magnetic head device and a magnetic tape, comprises a capstan shaft for driving the magnetic tape when the magnetic tape is pressed against the capstan shaft, so that the magnetic tape runs on the magnetic head device. A pinch roller presses the magnetic tape against the capstan shaft. A main chassis has the magnetic head and the capstan shaft mounted thereon. The magnetic tape and the pinch roller are mounted on a side chassis, with the slide chassis being movable relatively to the main chassis in a feed path between a first position in which the magnetic tape is wound on the magnetic head device for transmitting the magnetic signals therebetween, and a second position in which the magnetic tape is separated apart from the magnetic head device. A positioning arrangement is connected to both of the main chassis and the slide chassis to restrain a change in positional relation between the main chassis and the slide chassis in at least one direction when the magnetic tape is pressed against the capstan shaft by the pinch roller, and is separated from at least one of the main chassis and the slide chassis in the at least one direction in at least a part of the feed path when the magnetic tape is prevented from being pressed against the capstan shaft by the pinch roller.

Magnetic recording having a slidable chassis

There is provided a magnetic tape device capable of highly accurate positioning at a high speed. For this purpose, the head is driven in the direction of the width of the tape by eliminating the friction between the tape the head. In order to allow positioning in the direction of the width of the tape, even if a servo signal cannot be read from a servo track, the absolute position of the head from a reference position is detected, and the head is controlled based on the absolute position.

Magnetic tape device and method of controlling magnetic tape device

In an image processing apparatus for performing image processing of a processed object by displaying the processed object and an operating cursor on an image display device, and by operating the operating cursor according to three-dimensional actions of the hand and the fingers of an operator, a processing function and a shape of the operating cursor are changed by judging the meaning of the three-dimensional actions of the hand and the fingers to support understanding of the processing function.

Three-dimensional input device with displayed legend and shape-changing

In a tape loading device of the invention, a tape is taken out by tape guides mounted on an inclined loading ring, and the loading ring is rotated to wind the tape on a rotary drum from one side thereof. An auxiliary inclined guide is provided between the rotary drum and the leading tape guide. Only during a loading operation, the auxiliary inclined guide contacts the tape, while angularly moved about the leading tape guide. When the loading operation is completed, the auxiliary inclined guide is disengaged from the tape. With the provision of the auxiliary inclined guide, the tape is prevented from being twisted between the rotary drum and the leading tape guide.

Tape loading device and magnetic conversion apparatus

A magnetic recording/reproducing apparatus includes a head for performing recording/reproducing, a chassis for positioning the head, a cassette holder for positioning a cassette on the chassis, the cassette including an opening portion through which a recording medium is received or drawn out, a cassette holder supporting member for supporting the cassette holder on the chassis, and a casing which contains these component parts. The cassette holder supporting member has a substantially U-shape, facing three side surfaces of the cassette except the opening portion, and includes integrally formed fastening portions to be secured on the casing. The cassette holder supporting member is fastened to the casing through two fastening portions, and the chassis is directly fastened to the casing in one portion of the chassis.
