Title: Photosensitive material processing device
Inventor: KANEKO MASATOSHI
IPC: G03D3/06
Filed: 1993-05-14
Abstract: PURPOSE:To prevent the unnecessary supply of replenishing liquids to processing tanks. CONSTITUTION:The results of detection of liquid level sensors disposed in respective processing tanks are taken in and whether there is the processing tank having the liquid level below a reference level or not is decided (steps 150, 152). An alarm is triggered and a massage reporting the fall of the liquid level is displayed on a display if an ordinary operation mode is set (steps 156, 158). As a result, an operator is able to recognize the fall of the liquid level and instructs that the supply of the replenishing liquid is not executed by operating a replenishment selection switch if the operation, such as withdrawal of a rack from the processing tank, is carried out. The decision of a step 162 is denied and the supply of the replenishing liquid to the processing tank is not executed. The replenishing liquid is supplied until the liquid level attains the reference level when the supply of the replenishing liquid is instructed (steps 164 to 168).

Abstract: PURPOSE:To form a driving element as a unitary body by using a conventional laser diode wafer, by a constitution, wherein current narrowing is performed in its p-n-p-n structure in a laser diode part, the laser diode part and a thyristor part are electrically isolated, and optical coupling is possible. CONSTITUTION:An n-InP layer 5 is grown on a flat p-type InP substrate 4. A V groove is formed in the grown wafer. Double heterojunction structures 6-8 comprising InP/InGaAsP are formed so as to bury said groove. The energy gap of the active layer 7 is smaller than those of the upper and lower InP layers 6 and 8. Optical absorption is selectively yielded only in the InGaAsP for the light in the wavelength region from the vicinity of the energy gap of the InGaAsP to the energy gap of InP on the side of a short wavelength. A signal can be inputted by the input of the light on the side of the p-type InGaAsP 7 in a thyristor B. Thus, by using an ordinary laser diode wafer, a modulating element, which can be modulated by an electric signal and an optical signal input, can be formed as a unitary body.
