The living condition of a resident is prehended by a sensor disposed in a room. Identification information and vital information transmitted from a portable transreceiver carried by the resident are monitored. An audio signal favored by the resident is sequentially reproduced while the level is adjusted in accordance with the current living condition and physical condition of the resident.

Audio apparatus

The audio apparatus of the invention has: vital information detecting means for detecting vital information of a resident; a database which is configured by information based on the vital information, and in which at least vital information of the resident is accumulated; audio signal information generating means for, when vital information is detected by the vital information detecting means, referring to the vital information of the database, and for generating predetermined audio signal information at the detection; and audio signal producing means for producing an audio signal to the resident, the audio signal being based on the audio signal information generated by the audio signal information generating means.

An image recording machine has a plurality of light sources capable of emitting light independently for exposing a part of a photographic film without causing double exposure and with a printing controller. At least one of the light sources is caused to flash continuously for printing codes for timing during film transport, other light sources are caused to flash in synchronization with flashing of the light source for printing codes for photographing information, and the light source for printing the codes for photographing information is caused to flash for printing reference codes which are to be the judgment standards for the codes for photographing information.

The present invention relates to a method of and an apparatus for emitting light in ice, to be applied to an ice skating rink and the like. With the apparatus for emitting light in ice according to the present invention, when light emission sources are light emitting diodes (LED), LED mounting blocks are used and laid on a concrete floor, so that mounting works can be facilitated. Additionally, LED are used as the light emission sources, so that a possibility of ice melting can be eliminated. Furthermore, with the apparatus for emitting light in ice according to the present invention, when miniature incandescent bulbs are used as the light emission sources, the miniature incandescent bulbs disposed in transparent vinyl chloride tubes are laid on the concrete floor, so that a special water-proof measure can be dispensed with. Furthermore, air is delivered into the tube, whereby heat in the tube is prevented from being stagnant in the tube, so that the ice melting is avoided.

A range finder wherein the quantization of analog outputs from light receptor elements for converting an optical image into an electrical signal is accomplished by comparing the outputs from at least two of the light receptor elements in each group, by dividing the outputs into the following three cases: one output is greater than the other; both are equal; and one is smaller than the other.

Range finder

In cameras having an automatic exposure control of the through-the-lens photometric type, light exposure is determined by a photoreceptor responsive in turn to photometric sensitivity distribution. Such distribution can be determined by overall photometry, weighted photometry and spot photometry as controlled through the use of an electro-optical element serving as a focusing screen between the reflected incoming light and the photoreceptor. The photometric mode is varied by changing the applied voltage on the electro-optical element.

Photometric method for cameras

A camera having a microprocessor made receptive of various photographic informations through interrupt processing. The information at a higher priority level of said various photographic informations such as a release signal, a photometry start signal and a photometry introduction signal is fed to said microprocessor by the interrupting operation having a shorter period than that of the information at a lower priority level. The interrupt processing are periodic ones, and wherein an inequality of m&lt;n holds when the information at the higher priority level of said various photographic informations is fed with a period m times as long as an interrupt period whereas the information at the lower priority level is fed with a period n times as long as said interrupt period.

Camera with microprocessor

A variable illumination flash apparatus includes a main capacitor in parallel with a flash lamp and power source for normally supporting triggered discharge illumination of the lamp. A plurality of secondary circuits each containing a series-connected silicon controlled rectifier and secondary capacitor are disposed in parallel with the main capacitor and are individually selectively actuatable to store additional electric charge for further supporting lamp illumination. Each secondary circuit is actuated only when additional illumination is required for a subequent flash operation, thereby promoting efficient conservation of the power source in that no power is drawn from the source and stored in the capacitors unless needed for the immediately subsequent flash operation.

Variable electronic flash light equipment

The invention is directed to an arrangement controlling the film winding mechanism of a camera. In particular, the take-up amount of the film is monitored, and if the take-up amount of the film does not fall within the prescribed amount of film within a prescribed period of time, this is detected and a control circuit is actuated to stop the film-winding operation.

Film winding device

A camera which includes a liquid crystal focusing screen and an exposure control circuit that measures light reflected from the subject to be photographed after its passage through the liquid crystal screen is further provided with a circuit for compensating the light value determined by the exposure control circuit when operating voltage is not applied to the focusing screen so as to thereby compensate the amount of light measured through the screen when the nonapplication of operating voltage to the focusing screen causes the screen to transmit light therethrough less readily than when operating voltage is applied thereto.

A color transfer copying process for forming a colored image corresponding to an original by repeating prescribed times the procedures of projecting a reflected ray image from the original to be copied on a photosensitive material uniformly charged by a charging electrode through a filter to form an electrostatic latent image on the photosensitive material, converting the latent image to a toner image by using a powdery developer containing a coloring toner and transferring electrostatically the toner image onto a transfer sheet, while using selectively blue, green and red filters. Said process is characterized in that an electrode is disposed in the vicinity of a transfer passage for the transfer paper so that it acts on the transfer paper after completion of the transfer operation and said electrode is energized in regular sequence with the same frequency as that of the transfer operations or as that of the transfer operations exclusive of the final transfer operation to neutralize or diminish the retention charge of the coloring toner transferred onto the transfer paper at the transfer operation. It is made possible at the subsequent transfer operation to transfer and superpose a predetermined quantity of the coloring toner of the coloring toner image on the photosensitive material onto the transfer paper even in areas overlapped with the coloring toner image formed at the preceding transfer operation. A direct current having a polarity reverse to that of the transfer electrode for transferring the toner image to the transfer paper is applied to said charge-removing electrode.
