Title: Copying machine
Inventor: YOSHIDA KEIICHI
IPC: G03G15/04
Filed: 1987-04-09
Abstract: PURPOSE:To omit the waiting for the rise of the luminous energy of fluorescent light in copying operation by separately providing a fluorescent light switch and a main switch and previously lighting the fluorescent light. CONSTITUTION:The main switch 18 and the fluorescent light switch are separately given, and the latter 25 can turn on the fluorescent light 19 alone. The fluorescent light switch 25 is composed of two contacts 26 and 27. First, when the switch 25 is pressed, both the contacts 26 and 27 are closed to heat the filaments of the fluorescent light 19, which lead to discharge. Turning the switch 25 off when the light 19 is ready to light, the contact 27 is opened, while keeping the contact 26 on. The action of a stabilizer 21 turns on the light 19. In case of turning off the light 19, the switch 25 is again pressed to open the contact 26. Then a power source is cut off to turn off the light. Thus an operator can turn on the fluorescent light prior to copying operation. When a room temperature is low, for instance, an exposure light source is previously turned on; therefore the operator need not wait for the rise of its luminous energy.

Abstract: PURPOSE:To obtain the titled element whose luminous efficiency is sufficiently excellent as the light source for optical communication even by low current injection type by a method wherein a GaAlAs double hetero type junction is formed by successively laminating a P type GaAlAs clad layer, an N type Ga1-xAlxAs active layer, and an N type GaAlAs clad layer on a P type GaAs substrate. CONSTITUTION:The P type GaAlAs clad layer 2, N type Ga1-xAlxAs active layer 3, and N type GaAlAs clad layer 4 are formed by lamination on the P type GaAs substrate 1. It is sufficient that the value (x) is approx. 0<=x<=0.3 in order that said active layer 3 becomes in direct transition. Besides, the active layer 3 (0<=x<=0.3) should have the growing temperature at 830-829.9 deg.C, cooling speed at 0.1 deg.C/min, and is doped with Si. In case of doping the active layer 3 with Si in such a manner, it is generally known that said layer grows in P type; however, this active layer turns to an N type layer according to the condition of growing temperature and Si doping amount. Further, the light emitting element thus turning the active layer 3 to N type improves about double in the luminous efficiency as compared with the case of said element turned P type.
