Patent JP-S5784605-A (JP)
Title: Automatic gain control system
Inventor: HIBI MICHIO
IPC: H03G3/30
Filed: 1980-11-17
Abstract: PURPOSE:To extend the operating range, by storing an AGC signal level immediately before when the period T of an input signal is longer than a tracking time of an AGC circuit and fixing the gain of an amplifier with the storage until the period T is shorter than the tracking time. CONSTITUTION:An optical pulse train with a period T having DC or AC component is inputted, IN1, IN2, the level of an output A of a main amplifier 2 is checked 6 to discriminate if the level is a small value tau2 than an operating time constant tau1 of an AGC signal generating circuit 4 and within an AGC operation possible range. That is, the frequency of the output A is compared with the reference or threshold value and when tau2<tau1, a detection signal D is generated. An AGC signal holding circuit 5 passes directly an AGC signal B at the circuit 4 when the signal D is produced to change the gain of a preamplifier 1 and stores the signal B immediately before when the signal D is not generated, and the gain of the amplifier 1 is fixed to a prescribed value based on the signal B until the signal D is produced at T<tau2<tau1(tau1')<tau2. Thus, the output level of the main amplifier 2 is kept constant independently of the level fluctuation of an input IN to obtain a pulse train reproduced correctly from a comparator 3.

Filed: 1995-06-28
Abstract: PURPOSE: To improve machining precision and finishing precision by comprising the specific % by weight of Zn and the rest of Cu substantially and setting the composition in an area mainly taking a β phase. CONSTITUTION: A quantity of Zn is increased, and one/two kind/kinds of metal/ metals in Al, Si, Sn, Ti, Fe, Zr, Mn, Cr, Ni, Ag, Co is/are added to Zn.

Title: Load driving circuit
Inventor: SUEYOSHI SUSUMU
IPC: H03F3/217
Filed: 1980-11-19
Abstract: PURPOSE: To reduce the power consumption, by generating two AC voltages of square  waveforms and subjecting the first AC voltage to pulse width modulation in accordance  with an input signal and taking out the difference between a voltage, which is obtained by rectifying and integrating this output, and a voltage obtained by rectifying  and integrating the second AC voltage.  
     CONSTITUTION: An AC voltage V 1  is rectified, and the obtained voltage is inputted to  an inverter 3, and the first and the second AC voltages are generated from the all  winding and the intermediate tap of a secondary winding L 2  of a transformer T. A  pulse width modulating means 6 is connected to one end of the winding L 2 . In the  means 6, a switching element 9 is driven by the saw-tooth wave signal from a modulation signal generating circuit 10, and the first AC voltage is modulated by the pulse  width corresponding to the level of an input signal V i . The voltage of the square waveform subjected to pulse width modulation is rectified and integrated by a rectifying and  integrating means 7, and the output is sent to a load RL such as a speaker. The second AC voltage is recrified and integrated by a rectifying and integrating means 8, and  the output is sent to another terminal of the load RL. Since the load RL is driven by  analogue waveform components where DC components of the differencial voltage between outputs of means 7 and 8 are eliminated, the power consumption is reduced.

Title: Method of detecting jamming in hole of printed circuit board
Inventor: IMAMURA ICHIRO
IPC: B23B49/00
Filed: 1984-08-03
Abstract: PURPOSE:To make it easy and accurate to detect the jamming in each hole of a printed circuit board, by placing a pattern film having land images drawn thereon, coincidently on the printed circuit board after the holes are made therein, and by uniformly sprinkling a magnetic powder on the film, and examining where the magnetic powder may possibly be gathered. CONSTITUTION:A pattern film 12 is placed on a printed circuit board 11 in such a manner that land images 12a drawn on the film coincide with the holes 11a of the printed circuit board. A magnetic powder 13 is then uniformly sprinkled as a thin film on the film 12. If there is a broken drill portion 14 jammed in a hole 11b of the board 11, the magnetic powder 13 near the hole 11b is magnetically attracted through the broken drill portion so that a gathered magnetic powder portion 13a is formed on the hole. The hole 11b jammed with the broken drill portion 14 can be detected by finding the gathered magnetic powder portion 13a through eyesight. It is thus made easy and accurate to detect the jamming in each hole of the board 11.

Filed: 1985-07-25
Abstract: PURPOSE:To eliminate the prefetch of unnecessary data by providing a data buffer having specific capacity and a data buffer control part and limiting the capacity of the data buffer logically during operation in some mode. CONSTITUTION:When data from a main memory device is stored in the data buffer by four bytes while a device is in writing operation in byte multichannel mode, a data bus acknowledge signal 15 is sent to a data bus request control part 41A, a data bus request latch 23 is reset, and a data bus request signal 14 never becomes insignificant if the data stored in the data buffer does not exceeds four bytes. Consequently, when the device is in writing operation in byte multichannel mode, the data buffer which has large capacity actually is usable as a buffer with four-byte capacity. When, however, the device is in reading operation in block multichannel mode, the data buffer is usable as a large capacity buffer.
