Abstract: PURPOSE:To set a transmission quality to above some reference level by providing a variable amplifier whose amplification degree is varied in accordance with an amplification degree setting signal, and a temperature controller for varying a temperature of a semiconductor laser in accordance with a temperature setting signal. CONSTITUTION:An optical output from a semiconductor laser 50 is transmitted to an optical receiver by a single mode fiber 63, but a branching device 56 is inserted on the way, a part of a transmitted optical signal is fetched, converted to an electric signal by a photodetector 57, and levels of a signal, a distortion and a noise contained in said signal are detected by a signal level detector 58, a distortion level detector 59, and a noise level detector 60, respectively, and sent to a control part 61. In the control part 61, differences between the signal level and the distortion level, and between the signal level and the noise level are derived, and compared with a set reference level, respectively. If one of them is below the reference level, an amplification degree of a variable amplifier 62 or a temperature set value of a temperature controller 54 is varied so that both of them become above the reference level.

Title: Alarm circuit system
Inventor: MEGURO MASAO
IPC: G10K15/04
Filed: 1978-01-20
Abstract: PURPOSE: To improve the sensitivity of alarm system by constituting a circuit in which an alarm is generated by ocillating an oscillation circuit only when the detection circuit functions.  
     CONSTITUTION: When there is no resisting body to be detected such as for example water leakage between the pair of sensors, Darlington connected detecting transistors TRQ 2  and Q 3  are "OFF" and, therefore, the base current does not flow through oscillation transistor TRQ 1 , which is functioning as a load in portion of the primary side of transformer and, consequently, there is no oscillation. However, when there is a resisting body between sensors, TRQ 2  and Q 3  are turned "ON", base current flows through TRQ 1 , the main circcuit oscillates as a blocking circuit and alarm is is given form speaker SP. Since this circuit amplifies even when the current is very  weak, a resisting body of even very high resistance can be detected. When the resistance of body to be detected is comparatively low, one transisitor can be used  instead of Darlington connection.

Filed: 1990-01-13
Abstract: PURPOSE:To increase the allowable changing range of an input signal by providing a gain changing means to change in steps the amplification gain of a proportion circuit in accordance with the level of the input signal. CONSTITUTION:A series circuit 15 consisting of a resistance R1 and two diodes 14a and 14b connected in adversely parallel to the R1 is connected in parallel to a feedback resistance R2. The adverse withstand voltage is applied to both diodes 14a and 14b, and this adverse withstand voltage can well withstand the voltage having the large absolute value even though the absolute value E of the both-end voltage of the R2 increases in response to the voltage Vi, i.e. the value of an input signal 5. In this case, the amplification gain of a proportion circuit 16 is changed by a gain changing means 15 despite a big change of the level of the signal 5. Thus it is possible to obtain the position of a control subject where the correct correspondence is always secured between the level of an error signal 4c and the level of the signal 5. As a result, an allowable changing range is increased for the signal 5.

IPC: F02D11/10
Filed: 1993-01-14
Abstract: PURPOSE:To enable fail safe in the case where two electromagnetic clutches are in connecting condition by disabling that a valve is moved from a throttle valve side to an acceleration pedal side in valve opening direction. CONSTITUTION:In a connector 13, movement of a throttle valve is transferred from an acceleration pedal side to an acceleration drum 6 side in valve opening direction by a pair of engaging members, but movement of the throttle valve is not transferred from the acceleration drum 6 side in opening direction. When an electromagnetic clutch 8 is fixed in its connected condition and electrification of an electromagnetic clutch 12 is carried out so as to make both electromagnetic clutches 8, 12 in connected condition, the acceleration pedal is not operated in throttle valve opening direction by a DC motor 9 since movement of the throttle valve is not transferred from the throttle valve 1 side to the acceleration pedal side in opening direction by the connector 13. It is thus possible to prevent the throttle valve 1 from opening more than necessary without increasing the opening degree of the acceleration pedal.
