Title: Optical transmitter
Inventor: KOBAYASHI IPPEI
IPC: H04B10/50
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmitter having an automatic power control circuit capable of emitting output light within a standard from a laser diode even in a transient response to interrupt light output or to cancel the interruption of light output. SOLUTION: One part of output light from an LD 11 for outputting signal light 10 corresponding to a driving current is received by a photodiode 13, a current corresponding to that light reception power is converted to a voltage value by a current/voltage converting circuit 14, and an average voltage V1 is detected by an average value detecting circuit 15. The average voltage V1 and a reference voltage V2 corresponding to a mark rate outputted from a reference voltage control circuit 16 are inputted to an optical output control circuit 17, and a laser driving circuit 19 is controlled through a driving current control circuit 18 so that a current value higher than a preset value can not flow by the LD 11 concerning a driving current to be injected into the LD 11.  By controlling the average voltage V1 and the reference voltage V2 through an excessive output preventing circuit 41 during response time required for light output interruption or its cancel, the generation of excessive light output can be prevented.

Title: Liquid-level measuring method of liquid helium
Inventor: MORIYAMA TAKASHI
IPC: G01F23/22
Filed: 1984-06-25
Abstract: PURPOSE:To decrease the heating loss of liquid helium, by conducting a constant current through a piece of superconducting wire, measuring the voltages, which are applied on the superconducting wire at a specified time interval, and cutting the current when the difference between the average value of the voltages and the present measured value of a voltmeter is settled within a specified allowance. CONSTITUTION:A switch 3 is closed, and a constant current is applied across both ends of a piece of superconducting wire 1 from a constant current power source 2. A voltage applied on the superconducting wire 1 at this time is stored in a RAM8 through an operating amplifier 4 and an A/D converter 5. When the times of measurements of the voltages applied on the superconducting wire exceed the specified times, computation of average of the measured values of a voltage up to a plurality of times in the past is carried out by a CPU7. When the difference between the average value and the present measured value of the voltmeter is settled within a specified allowance, the switch 3 is opened. Thus the current to the superconducting wire 1 is cut OFF. Then the CPU7 subtracts the present measured value of the voltmeter from the full-scale voltage of the superconducting wire when liquid helium indicates the full scale. Then value is multiplied by a constant coefficient, and the level of the liquid helium is computed.

Title: Intake rotary valve device for two-cycle engine
Inventor: AKUTSU SHIGEMITSU
IPC: F02B75/02
Filed: 1983-07-19
Abstract: PURPOSE:To appropriately control the timing of intake port to open and close, by turning to displace respective rotary valves in the reverse direction to each other under the effect of centrifugal weight in response to the increase of engine r.p.m., the rotary valve acting to determine the opening/closing timing of intake port. CONSTITUTION:As a driving shaft 21 is rotated in synchronism with the rotation of crankshaft upon an engine being started, an integral rotation takes place with a driving plate 28, a centrigugal weight 42, first and second rotary shafts, first and second rotary valves 33, 34 and the like. As the centrifugal weight 42 is retained in its retracted position during a slow speed drive under the action of return spring 44, the coupling pin 41 of second rotary shaft 27 comes into abutment with the R direction side end wall of slot 38 defined through the first rotary valve 33, whereby making the valve opening angle theta of intake port 10 relatively small, that is, as compared with the angle of alpha-beta. On the other hand, the centrigugal weight 42 is caused to extend under the action of centrifugal force and two rotary valves 33, 34 are caused to rotate each other via driving pawls 45, 56 during a high speed drive, and therefore the valve opening angle of intake port 10 is increased.

Title: Electronic watch with alarm
Inventor: NOMURA YASUSHI
IPC: G04C21/16
Filed: 1977-11-04
Abstract: PURPOSE: To let one switch serve as a snooze switch and an alarm silence switch by providing a switch control circuit which is provided with two detection circuits capable of detecting the operation time and operation times of the switch respectively independently.  
     CONSTITUTION: A switch 18 is a switch serving both as an alarm silence and snooze switch. When the switch 18 is short-pushed once, this short push signal is transmitted to a snooze switch circuit 22 and is also transmitted to an alarm silence circuit 20. When an alarming unit 16 is actuating and an alarm is being given, the short push of the switch 18 causes the alarm kto silence temporarily and snooze action takes place. Since the signal of the operation times of the switch 18 is directly transmitted to an alarm silence circuit 20, the opening and closing operations of plural times of the switch 18 including the short-push operation casue an alarm coincidence memory circuit 12 to be reset by the signal from the alarm silence circuit 20, whereby the alarm is silenced.

Title: Circuit for driving word line in bipolar memory
Inventor: MITSUMOTO KINYA
IPC: G11C11/415
Filed: 1982-07-30
Abstract: PURPOSE:To shorten an access time, by connecting an emitter follower using a PNP transistor together with another emitter follower using an NPN transistor to a word line and complementarily driving these transistors. CONSTITUTION:When levels of input signals Vin1 and Vin2 are changed and the electric potentials of the base of transistors (Tr) Q1 and Q2 are lowered, the electric potential of the base of an NPN Tr Q3 is made higher than that of a word line W and a large collector current is made to flow to the Tr Q3 and, at the same time, a PNP Tr Q4 is cut off by the electric potential of a node N2. Therefore, an electric current is made to flow through the line W and the stray capacity Cs of the line W and equivalent capacity of a memory cell are charged and the level of the line W rises rapidly. When one side of the input signals is changed into a high signal, electric charges of stray capacity Cs, etc., are attracted by a constant-current source 1b and the electric potential of the word line W is slowly lowered. Since the falling speed of the electric potential of the node N2 is much faster than that of the line W, the Tr Q4 is strongly turned on and a large collector current is made to flow and the electric potential of the word line W rises rapidly, when the electric potential of the base of the Tr Q4 is further lowered by the amount of VBE from the electric potential of the line W.
