Title: Operation center detecting device of actuator
Inventor: TAKEUCHI TOYOAKI
IPC: G11B7/09
Filed: 1982-12-23
Abstract: PURPOSE:To detect quickly and exactly in which side of the mechanical center the operation center of an actuator is positioned, and to execute a stable tracking control by constituting so that a signal for showing the polarity is outputted at the time point when the polarity of the drive voltage is inverted. CONSTITUTION:A D-FF circuit 6 is not inverted even if a clock is sent out at the time t1 when the operation center of an actuator 2A is in about the inside M of the mechanical center and an output of the first comparator 5 is in a high level.

Title: Semiconductor laser output control equipment
Inventor: TAKEYAMA YOSHINOBU
IPC: B41J2/44
Filed: 1986-09-30
Abstract: PURPOSE:To prevent the deterioration of a semiconductor laser excluding excessive current flow in the semiconductor laser, by driving the semiconductor laser with the output signal of an error amplifier after sample-hold applying a timing signal, and prohibiting the timing signal by a protection circuit when the output signal of a light detection circuit is smaller than or equal to a specified value. CONSTITUTION:A photo-diode generates a current proportional to the light output of a semiconductor laser 1, and an error amplifier 4 amplifies the difference between the output voltage VM of an amplifier 3 and a reference voltage Vref. This value is subjected to sample-hold by a timing signal in a sample-hold circuit 5. A driving circuit 6 for semiconductor laser flows a current corresponding with the output signal of the sample-hold circuit 5 into the semiconductor laser 1. Thereby the driving current of the semiconductor laser 1 is stabilized as a value corresponding with the reference voltage Vref, and the light output of the semiconductor laser 1 is controlled so as to be constant. When the light output of the semiconductor laser 1 is less than or equal to a specified value, and the output signal of the amplifier 3 is less than or equal to the threshold level VTH, a gate 7 turns OFF, the timing signal is prohibited, and the sampling operation of the sample-hold circuit 5 is interruped.

Title: Luminaire
Inventor: TANAKA KAZUHO
IPC: H05B37/02
Filed: 1992-08-31
Abstract: PURPOSE:To provide a luminaire in which a malfunction caused by light noise can be prevented. CONSTITUTION:Alternating current voltage of commercial alternating current electric power supply E is rectified and smoothed by a rectifying and smoothing circuit 11, and this rectified and smoothed voltage is converted into a high frequency alternating current by an inverter circuit 12, and an electric discharge lamp FL is lighted. The alternating current peak is detected by an electric power supply peak detecting circuit 13 according to a waveform of the alternating current voltage, and receiving sensitivity of a receiving part 3 is controlled by a level control part 14. Since the electric discharge lamp FL repeats brightness and darkness in frequency twice the commercial alternating current electric power supply E, light noise having frequency twice the commercial alternating current electric power supply E is inputted to the receiving part 3. In order to prevent the receiving part 3 from causing malfunction or inoperativeness due to the light noise, the receiving sensitivity of the receiving part 3 is reduced in a period during which an absolute value of instantaneous voltage of the alternating current voltage is not less than a prescribed value.

Title: Buffer control system for communication controller
Inventor: FUJISAKI KUNIO
IPC: G06F13/00
Filed: 1988-09-19
Abstract: PURPOSE:To prevent the deterioration of the transmission efficiency by using a reception buffer of a communication controller to perform the temporary reception in the case a reception buffer of a shared memory has no margin. CONSTITUTION:The data received via a communication circuit 40 is given to a process part 12 of a communication controller 10 and then stored as it is in a reception buffer 22 of a shared memory as long as the buffer 22 has a margin. This operation is repeated. The part 12 stores the received data temporarily into a reception buffer 13 at the time point when it is known that the buffer 22 has no margin. This operation is repeated hereafter. Thus a receiving process is through. In such a constitution, a retransmitting procedure or a reception suppressing procedure is not required and therefore the transmission efficiency is improved.

Title: Timepiece with illumination control device
Inventor: OSHIMA KENJI
IPC: G04B19/30
Filed: 1985-10-18
Abstract: PURPOSE:To improve the sensitivity of an infrared-ray sensor by making infrared-ray from the outside pass through a light leading cylinder part without being obstructed, and making it incident on the infrared-ray sensor. CONSTITUTION:An edge part 6b of an opening part 6a is bent toward a fitting plate 1. Also, an optical sensor 11 is provided at a position which has been separated enough from an illuminating light source 10 in a front cover 6. In this state, when the outside is dark, when a man waves a hand at a position which is separated by a prescribed distance from a timepiece in front of the timepiece, the infrared-ray which has been emitted from the human body is made incident from a light leading cylinder part 8 and detected by an infrared- ray sensor 9. The light source 10 is lighted thereby, and this light transmits through the edge part 6b of the opening part 6a and illuminates a time display part 7. Also, the sensor 11 does not react to brightness by lighting of the light source 10 and does not send a signal to a circuit block 12. Therefore,the light source 10 continues stably the lighting. On the other hand, when the outside is bright, the sensor 11 reacts and sends a signal to the block 12, therefore, even if a man waves a hand in front of the timepiece, the light source 10 is not lighted.

Title: Electric field absorption type optical modulating circuit
Inventor: SUZUKI KAZUHIRO
IPC: G02F1/015
Filed: 1991-09-12
Abstract: PURPOSE:To increase a code error rate by performing control so that the OFF state of the light signal outputted from an electric field absorption type optical modulator is a complete extinction state. CONSTITUTION:The electric field absorption type optical modulator 1 varies in light transmissivity with an impressed driving voltage Vd, and performs ON/OFF control over the input light O1 from a light emitting means 3 according to the light transmissivity to output the light. A driving voltage control means 20 holds the peak value of the driving voltage Vd impressed to the electric field absorption type optical modulator 1 at a determined value and when the peak value of the driving voltage Vd is to a level at which the electric field absorption type optical modulator 1 completely cut off the input light O1, the light signal of OFF level can be outputted at all times by completely cutting off the light from the modulator 1, so the OFF level becomes the level of no light emission. Consequently, when the OFF level is detected on a reception side, the level is never misdetected as an ON level.

IPC: C21D9/46
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a multi-phase structure stainless steel strip which has excellent shape and high strength and high ductility. SOLUTION: The cold-rolled stainless steel strip 6 containing, by weight, at least <=0.1% carbon and 10-20% chromium is heat treated under a prescribed tension. In the heat treatment, the stainless steel strip is heated at or over the temperature where the stainless steel is in two-phase region of ferrite and austenite and below 1100 deg.C in a heating furnace 3, and cooled at a cooling rate of 30-100 deg.C/sec from the heating temperature down to 80 deg.C in a natural cooling zone 4, and water-cooled from #80 deg.C in a water-cooling zone 5. Because austenite is transformed into martensite during the cooling, the multi-phase structure of ferrite + martensite of high strength and high ductility is formed. Also, because the cooling is controlled under an appropriate tension, a multi- phase structure stainless steel strip excellent in shape is manufactured.
