Title: Control device of pwm inverter
Inventor: MUTO NOBUYOSHI
IPC: H02P21/00
Filed: 1986-04-14
Abstract: PURPOSE:To prevent instantaneous trips of an inverter even if load of a prescribed value or more is applied, by a method wherein the inverter frequency is decreased when the load is increased. CONSTITUTION:Inverter frequency command omegat is controlled by signal in addi tion of inverter frequency setting value omega1 and frequency correction signal omegas proportional to active current It from a torque limiter circuit 100.

Title: Computer program for factorization
Inventor: SUGAWARA MASATOSHI
IPC: G06F17/10
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To surely obtain factors when an indefinite equation is solved by making a remainder factor (n) lie in factorization of odd number N. SOLUTION: When N is a square number and expressed as N=P<2> , a remainder factor (n) is made to zero at P-th column of N-th row, and hereafter, (n) in the column P is increased by one (1) for every increase by four (4) in N and if (n) is a multiple of P, the N can be divided by P. Also, even if a multiple of P is deducted from (n), a relationship between P and (n) remains unchanged. (P-2) is deduced from (n) in (P-2)th column of a row where N<2> =P, 2(P-4) in (P-2)th column, and if this deduction is continued until P becomes 3, then, a progression of (n) can be obtained. Letting X=Q-Q', the odd number progression is expressed as (pm-2X), the progression of (n) is expressed as X<2> , and a progression of (n) to a given N becomes a progression where a number B of (N-No) divided by 4 is added to a progression of (n) of a maximum odd square number No less than N.  If (X<2> +B) can be divided by (Pm-2X), N should include factors. Therefore, N can be factorized, if X is solved so that (t) in an equation becomes integers.

Title: Structure for key switch
Inventor: MITSUIE KIYOTAKA
IPC: H01H13/52
Filed: 1992-03-06
Abstract: PURPOSE:To dispense with a metal spring which has been conventionally used in structure for a key switch so as to reduce component parts and prevent human-initiated erroneous assembling or the like in assembling process. CONSTITUTION:Upon pushing a plunger 1 with a piston in the initial position, air 4 inside a cylinder is compressed to generate repulsive force for returning the plunger 1 with a piston upward. When the plunger 1 with a piston is released after complete depression, it is returned to the initial position by the repulsive force of the compressed air. Consequently, a switch is operated so that the same function can be realized without a metal spring as conventional.

Filed: 1993-04-12
Abstract: PURPOSE:To facilitate the handling of long data, and to improve the work efficiency of a design by storing positions of plural data output areas by relative coordinates by an output image store means. CONSTITUTION:Item data d1 is outputted to a data area 1 (S1). In this case, when the quantity of the item data d1 is large, and cannot be held entirely in three lines being a set range of the data area 1 (S1), since this data area 1 (S1) is an extensible set area, a range of the data area 1 (S1) is enlarged automatically. Accordingly, an end position B of this data area 1 (S1) becomes insufficient. In such a way, the end position B is determined in accordance with the quantity of data. Subsequently, item data d2-d4 are outputted to data areas 2-4 (S2-S4), and start positions C, E and G in this case are calculated from a value of a relative coordinate against a Y coordinate of the end position B of the data area 1 (S1), and determined.

Abstract: PURPOSE:To compensate the unevenness of the characteristics of a horizontal reading circuit by detecting the output difference between the clamp output level and the signal output level of the horizontal reading circuit before and after the reset clamp of the input terminal of the horizontal reading circuit. CONSTITUTION:The horizontal read selection switching MOSFETs 17-1 and 17-2 are activated by the horizontal scan pulses phiS1 and phiS2, the signal voltages V01 and V02 are obtained at the output terminals of the load resistance 20-1 and 20-2 connected to the video lines 18-1 and 18-2 by the input voltage of a MOS source follower circuit with its source follower action. Simultaneously, the signal voltages of picture elements SIT 10-11 and 10-12 and a clamp output level appear at the voltages V01 and V02 of the lines 18-1 and 18-2 since the horizontal selection pulses phiS3-phiS5 are applied. Both voltages V01 and V02 are inputted to a correction circuit which fetches these voltages by an amount equal to the difference between the clamped output level and a signal output level. Thus, it is possible to obtain an output after correcting the variance of the input/output characteristics of the MOS source follower circuit.

Title: Envelope detection circuit
Inventor: SUZUKI TETSUO
IPC: H03D1/18
Filed: 1991-04-17
Abstract: PURPOSE: To suppress distortion with high detection sensitivity even at a very small input without being saturated in the case of a high signal level input by providing a current control circuit controlling an output current to be decreased as an amplitude of a detection signal is increased and a differential amplifier circuit receiving the detection signal and using the output current as a current source in the detection circuit. CONSTITUTION: A DC amplifier section 2 is a differential amplifier circuit using an output current of a current control section 3 for a current source and amplifies an envelope detection signal received from a detection section 1 and providing an output to a resistor R3 being a load resistor RL. On the other hand, the current control section 3 varies an output current being the current source of the DC amplifier section 2 corresponding to a level of the detection signal. That is, the output current is controlled in a way that the output current is increased when the detection signal level is small and the output current is decreased when the detection signal level gets higher. Since the mutual conductance of the differential amplifier circuit is changed depending on the current from the current source, the gain of the differential amplifier circuit is changed.

Abstract: PURPOSE:To prevent a void from being produced in an insulating film for final protection use by a method wherein a silicon oxynitride film is formed on an insulating film on a semiconductor substrate by using bis(di-tert- butoxyaminosilane) imide as a raw material. CONSTITUTION:An insulating film 2 is formed on the surface of a semiconductor substrate 1 ; after that, Al wiring parts 3 are formed; then, a silicon oxynitride film is grown by a plasma CVD method by using [(t-C4H9O)2SiNH2]2NH bis (di-tert-butoxyaminosilane) imide) as a raw-material gas; a second insulating film 6 for final protection use is formed in the film.
