Title: Optical reception circuit
Inventor: OGAWA FUMIO
IPC: H04B10/69
Filed: 1989-04-13
Abstract: PURPOSE:To stabilize an AGC (automatic gain control) action when a reception level is low by providing a signal/noise detection circuit limiting the output voltage of a high voltage generator when the level of a signal and noise including in an equivalent amplifier is less than a prescribed value. CONSTITUTION:APD(avalanche photodiode) 1, the equivalent amplifier 2, an AGC control circuit 4 and the high voltage generator 3 constitute an AGC loop, and the signal/noise detection circuit 5 is added to the constitution, whereby the signal/noise level included in the output of the equivalent amplifier 2 is detected. When the signal/noise level is less than the prescribed value, the action of the AGC control circuit 4 is stopped and the control voltage at that time is held. Consequently, the output voltage of the high voltage generator 3 is limited to the value at that time, and low frequency which APD generates is prevented from increasing. Thus, the AGC action at the low reception level when low frequency noise increases can be stabilized.

Abstract: PURPOSE:To decide on the positioning state of the 2nd focus part and to mea sure a multifocal lens accurately by comparing the degrees of sphericity and the degrees of cylindricality of the 1st and the 2nd focus parts with each other. CONSTITUTION:When a bifocal lens is positioned, a microcomputer (MC) 7 instructs a data storage and short-distance part positioning through a data storage specifying member 10 and a short-distance part positioning start specifying member 11. When the data storage is specified, the MC 7 stores the degree S0 of sphericity and the degree C0 of astigmatism in a storage device 12. When the start of positioning is specified by the member 11, the degree S1 of sphericity and the degree C1 of astigmatism which are measured subsequently are compared with the degree S0 of sphericity and the degree C0 of astigmatism stored in the device 12. It is decided whether S1=S0 and when S1not equal to S0, it is decided whether C1=C0. Further, when S1=S0 or when C0not equal to C1, a defect in positioning is displayed on a display device 8 and when S1not equal to S0 and C0not equal to C1, normal positioning is displayed.

Title: Dewing preventing structure for laser scanning optical system
Inventor: YANO TAKAAKI
IPC: G02B27/00
Filed: 1990-04-10
Abstract: PURPOSE:To prevent dewing with simple structure at a low cost by preventing the generation of an air stream with an air stream generation preventing means and controlling air flow in a laser scanning optical system. CONSTITUTION:A scanning optical system unit 20 is covered with an air stream preventing cover 18 as the air stream generation preventing means. The air stream generation preventing cover 18 is placed by placing the bottom surface of its peripheral wall 18B on the upper surface of the bottom part of a case 30, and abutting its front edge, where the peripheral wall 18B is not formed, on the heat insulating wall 17. The bottom surface of an upper plate 18A is set as close as possible to the upper surface of the scanning optical system unit 20. Since the circumference of a polygon mirror 12 is thus covered with the air stream preventing cover 18, the generation of the air stream caused by the rotation of the polygon mirror 12 is prevented. Moreover, since the area of the scanning optical system unit is separated from that of an optical path refracting mirror by the heat insulating wall 17, the air flow between both areas is prevented. Thus, the scanning optical system can be prevented from dewing with the simple structure at low cost.

Filed: 1985-04-30
Abstract: PURPOSE:To suppress the leakage current and to attain sharp reading by providing plural light interrupting electrodes provided to cover nearly the entire face of a photoconductive layer in the broadwise direction and a switch means switching the electrodes to either power supply side or output side terminals. CONSTITUTION:When a switch Sa is kept thrown to the position of a terminal A and a switch Sb is thrown from the position of a terminal B to the terminal A succeedingly, a current flows to a photoelectric conversion element shown in a resistor Rbc in figure via switches Sb, Sc, and a voltage proportional to the current value is outputted to the terminal B. In this case, wiring electrodes 4a, 4b are connected to the terminal A and of the same potential, and wiring electrodes 4c, 4d-are all connected to the terminal B and of the same potential, then no current flows to photoelectric conversion elements except the element represented in the resistor Rbc, that is, no leakage current as with the case of a conventional example flows. Since the leakage current is not increased in this way, an element with high sensitivity and high output is realized.

Title: Controller for charging generator
Inventor: ISHIKAWA HITOSHI
IPC: H02P9/04
Filed: 1986-04-25
Abstract: PURPOSE:To alleviate a mechanical load for a driving belt by reducing the generating voltage of a charging generator in a predetermined range of a rotating speed which includes the rotating speed corresponding to the peak point of a driving torque. CONSTITUTION:A generating voltage is set to V0 when the speed of an engine 60 is N1 or lower in a controller 40 for a charging generator for controlling the generating voltage of the generator 50 driven by the engine 60. When the rotating speed is N1 or higher, if a headlamp or a sidelamp is fired, it is highest generating voltage V2. When the rotating speed is located between N2 having the peak value T0 of the torque and N3, it remains V2 if an air conditioner switch is OFF and it is V2 except the case. If N3<N<N4, it is set to V2, and if it is N4 or higher, it is V3. Thus, it can reduce a mechanical load applied to a driving belt 62.
