Title: Light receiving circuit
Inventor: WASHIKAWA AKIO
IPC: H04B10/40
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To input light on an appropriate level to a light module even when an input light level changes. SOLUTION: This light receiving device is provided with a photodetector circuit which detects a light input, a light output detector circuit 7 which monitors the level of an output signal of a variable light attenuator and a control part 8 which controls the variable light attenuator 3. The attenuator 3 initially makes an attenuation amount of an optical signal infinite. When an optical signal is inputted, a light input detector circuit 6 detects it and transmits information to the control part 8. The control part 8 gradually reduces the attenuation amount of the attenuator 3 and stops attenuation when light output that is detected by the circuit 7 enters a light receiving level of a light module 5.

Abstract: PURPOSE:To reduce the numbers of commutation auxiliary circuits and circuit elements by specifying a main circuit control rectifier for firing initially in case of starting. CONSTITUTION:When the firing sequence of a main circuit thyristor is in the order of thyristors Th1-Th6-Th2-Th3-Th5-Th1, commutation condensers necessary for initial charging are condensers C1, C3, at the positive arm side of a main circuit, and condensers C5, C6 at the negative arm side. Accordingly, in case of starting an inverter device, the thyristor Th1 is conducted at the positive arm side and the thyristor Th6 is conducted at the negative arm side for the prescribed time to initially charge the condensers C1, C3 and C5, C6. The stored charges of the condensers C1, C3 and C5, C6 remain charged until the thyristors Th2, Th4 are fired.

Title: Automatic answering telephone set with remote message listening without malfunction
Inventor: HASHIMOTO KAZUHASU
IPC: H04M1/652
Filed: 1981-09-05
Abstract: PURPOSE:To prevent malfunction, by distinguishing a remove control signal recorded at a remote control point of a device from a signal transmitted from a remote location. CONSTITUTION:Since a remote control signal at a remote control point of a device is far larger in the signal level than that transmitted from a line, a C4 is rapidly charged and the delay is made small. Thus, to the remote control signal inputted via the line, an output terminal 4 of an IC1 which is an AND gate goes to H level, but when a remote control signal recorded on a reception tape T-2 is reproduced, even when the signal passes through the same microfork Fb, the signal can not boost the output terminal 4 to the H level. Then, whether remote control signals of the same kinds come from internally or externally can be discriminated.

Title: Zoom lens
Inventor: IKEMORI KEIJI
IPC: G02B15/177
Filed: 1983-07-29
Abstract: PURPOSE:To make a titled zoom lens compact, and also to convert a photographing view angle at a zoom position of a wide angle end, to a wide angle, by moving independently the first lens group - the third lens group, in case of zooming. CONSTITUTION:The fourth lens group of a positive refractive power which is fixed in the course of zooming is place. Accordingly, the first lens group through the third lens group have a positive refractive power, therefore, its refractive power becomes weaker than a positive refractive power of the whole system. Also, when the refractive power of the third lens group is made the same as a conventional one, the refractive power of the first lens group and the second lens group can be made weaker than a conventional one, and an aberration variation due to zooming is reduced. Also, when zooming to a telephoto end from a wide angle end, the second lens group moves to the direction of an object side, and in this case, the third lens group is moved to the direction of the same object side as the second lens group. It is executed easily to make it compatible to make a zoom lens compact and have a high performance, by controlling a ratio of a moving extent of the third lens group against this second lens group.
