Patent JP-H05235727-A (JP)
Title: Semiconductor device
Inventor: KOMATSU TAKAHIRO
IPC: H03K17/22
Filed: 1992-02-25
Abstract: PURPOSE:To ensure resetting and to prevent malfunction by detecting a change in a voltage between a received 1st potential and a reference 2nd potential and generating a reset signal in response to a change in the voltage. CONSTITUTION:Transistors(TRs) Q1, Q2 whose gates receive an input potential form an inverter and an output signal phiR is outputted. Furthermore a capacitor C is connected between an intermediate node N1 and a power supply. The potential of the intermediate node N1 is set properly and a relation of V(N1)=(R 2/R1+R2)XVCC>=VT is in existence, where VT is a threshold voltage of the inverter comprising the TRs Q1, Q2. The potential of the intermediate node N1 keeps a potential being the VT or below between timings T1 and T2 by setting the resistance of the resistors R1, R2 and the capacitance of the capacitor C sufficiently large. Thus, the output signal phiR is at an H level between timings T1 and T2. Through the operation above, a change in the power supply voltage is detected and the signal phiR is generated.

IPC: G06F21/62
Filed: 1993-02-26
Abstract: PURPOSE:To provide a data storing circuit capable of preventing the generation of miswriting in a backup RAM even at the time of runaway and surely storing data in the backup RAM and a game machine provided with the data storing circuit. CONSTITUTION:A backup chip selecting signal 21f outputted from an address decoder 21 is supplied to the backup RAM 20 through an AND gate 30 and outputs from a permission circuit 31 and a runaway detecting circuit 41 are used for opening the AND gate 30. The circuit 31 outputs a permission signal 31a only when a prescribed ID signal is supplied from a CPU 22. On the other hand, the circuit 41 outputs a runaway detecting signal 41a when contradiction occurs between an access pattern and a read/write signal. The AND gate 30 suppresses the supply of a backup chip selecting signal 21f to the RAM 20 based upon the combination of the signals 41a, 31a.

Title: Multilayer wiring board with printed inductor
Inventor: KAMIMURA OSAMU
IPC: H01F17/00
Filed: 1992-02-25
Abstract: PURPOSE:To reduce a stray capacitance of a printed inductor and to prevent a decrease in a self-resonance frequency by providing a cutout on a ground layer, a wiring layer or a power source layer directly under or above the inductor through a dielectric layer. CONSTITUTION:A cutout 5 is provided on a ground layer or a power source layer 2 directly under a printed inductor 1 through a dielectric layer 4. Thus, a distance of the inductor 1 to the opposed ground layer, the power source layer becomes substantially a distance d' between the inductor 1 and the power source layer or the ground layer 3 to be substantially increased, and hence its stray capacitance is reduced. A self-resonance frequency ft of the inductor 1 is increased by the reduction in the stray capacitance to be effective to prevent a decrease in the frequency ft. Since the step of slotting the ground layer, the wiring layer or the power source layer is executed in the step of normally forming a pattern, the number of the steps is not increased at all. Accordingly, a multilayer wiring board with the printed inductor having excellent frequency characteristics can inexpensively be obtained.

Title: Thread drawing-out control device of sewing-machine
Inventor: MATSUBARA KENJI
IPC: D05B47/04
Filed: 1988-02-18
Abstract: PURPOSE:To obtain a good thread behavior as soon as possible after the sewing work is started by driving and controlling an electromagnetic actuator to draw out the corrected amount of thread while a control device is receiving the direction to correct from a thread amount correction device. CONSTITUTION:A thread drawing-out device 45 of a sewing-machine draws out a specific amount of upper thread 76 from a thread bridge 4. A thread drawing-out timing signal generator 87 outputs a thread drawing-out timing signal to CPU 91 at every specific timing, and a needle position signal generator 88 outputs a needle-up position signal, and a needle-down position signal. A control device C is composed of CPU 91, ROM 92, and RAM 93, and the RAM 93 furnishes the first memory M1 to store the loosening amount of the remaining upper thread while renewing in order, and a memory M2 to store the computed necessary thread amount N. By such a constitution, since the upper thread 76 is corrected and controlled to stop the drawing-out from the thread bridge 4 until the loosened amount of the upper thread 76 in the thread passage in the downstream of a thread gearing body is consumed perfectly, a good thread behavior can be obtained from the very early time.

Title: Reading method for picture information
Inventor: KOYANAGI HARUO
IPC: H04N5/907
Filed: 1981-03-18
Abstract: PURPOSE:To shorten the max. delay time up to the start of reading by reading 1 frame of picture information from the initial input of a horizontal synchronous signal after a reading start signal has been inputted. CONSTITUTION:A reading start signal is inputted at the time of a point t0. At the time of point t1 when a horizontal synchronous signal SH is initially inputted after the time t0, picture information obtained by A/D conversion is started to be read out and the horizontal synchronous signal SH is started to be counted up. The picture information is read from the left end of the 4th scanning line. When the reading of the picture information is ended at the time of point t2 (time TV passes from the time of point t1) when the succeeding horizontal synchronous signal SH is inputted after the counting value of the horizontal synchronous signal SH has reached the horizontal scanning times (n) for 1 frame, just 1 frame of the picture information up to the right end of the 3rd scanning line is read out. Thus, the max. delay time up to the start of reading can be shortened up to one horizontal scanning time.
