Abstract: In a process for producing a semiconductor light emitting device, first, a lamination including an active zone, cladding layers, and a current confinement layer is formed. Then, a near-edge portion of the lamination having a stripe width is removed so as to produce a first space, and a second near-edge portion located under the first space and a stripe portion of the lamination being located inside the first space and having the stripe width are concurrently removed so that a second space is produced, and cross sections of the active layer and the current confinement layer are exposed in the second space. Finally, the first and second spaces are filled with a regrowth layer so that a dopant to the regrowth layer is diffused into a near-edge region of the remaining portion of the active layer.

Abstract: This invention relates to an image recording method of recording a single pixel forming an image using a plurality of pulses by expressing gradation using a single pulse or a plurality of pulses having a larger pulse width expressing a superordination bit and a single pulse or a plurality of pulses having a smaller pulse width expressing a subordination bit, and an image recoding apparatus for carrying out the method and the like.

Abstract: A fingerprint image generating method and a fingerprint image recording sheet are provided which can take a clear fingerprint image easily and efficiently, without the process of wiping seal ink, with less chance to generate an unclear fingerprint image even in improper operation. A solution containing an electron-donating dye precursor is applied to a fingerprint face of a fingertip and then the fingertip is pressed against a recording film to which an electron-accepting color developer is applied. The electron-accepting color developer adsorbs the electron-accepting dye precursor to occur a coloring reaction on the recording film. The fingerprint image recording sheet includes a fingerprint image recording portion applying the electron-accepting color developer thereto and the electron-donating dye precursor applied portion to which the solution of the electron-donating dye precursor is applied.

Abstract: A compensator lens is driven by a second driving means such that the rear end of the focal depth of an object image at infinity coincides with a surface of image-formation irrespective of the movement of a variable lens when the object image is photographed. With this arrangement, the whole range of the focal depth can be effectively utilized, so that the range of photographing can be enlarged without focussing immediately after the power source is turned on as compared with the conventional zoom lens system. That is, even an object disposed at a close distance can be photographed without focussing as compared with the conventional zoom lens system which can utilize only the substantially half length of the focal depth. Furthermore, even when the object disposed at the closest distance is photographed, focussing can be made in a short period of time as compared with the conventional zoom lens system.

Abstract: A rinsing water supply system for supplying water to a rinsing unit of a developing apparatus in which photosensitive materials are processed and rinsed. The water supply system includes a pipe having a water supply passage through which water is introduced into the rinsing unit from a water source, a solenoid valve for opening and closing the water supply passage, and signal lines arranged along and integrally with the pipe and adapted for transmitting signals for operating the solenoid valve. This arrangement eliminates the necessity for installation of a signal transmission line independently from the water supply passage, for the purpose of transmitting signals for operating the solenoid valve.

Abstract: There is provided a method for processing a silver halide color photographic material which comprises processing the silver halide color photographic material with a color developer containing an aromatic primary amine color developing agent and a specific amino compound. According to this method the stability and color forming property of a color developer are improved so that the increased fogging problem in continuous processing is lessened and the processing time is shortened. There is also provided a color developer composition which can be used as the developer, as it is or after adjusting its composition.

Abstract: An irradiation image erase unit for erasing a residual image from a stimulate phosphor sheet with erasure light is disposed in the vicinity of an image read-out unit which converts light emitted from the stimulable phosphor sheet upon stimulation thereof into an electric signal. The irradiation image erase unit comprises a box-shaped casing having a slot for passage of the stimulable phosphor sheet therethrough into the casing, and erasure light sources disposed in the casing for emitting the erasure light. A pair of rollers is mounted on the casing adjacent to the slot for introducing the stimulable phosphor sheet into the casing. The rollers or a cover enclosing the rollers serves to prevent the erasure light from leaking out of the casing toward the image read-out unit.
