Title: Synchronous supervisory equipment
Inventor: TSUKADA KAZUO
IPC: G01S5/10
Filed: 1977-12-14
Abstract: PURPOSE:To detect a synchronous state with high precision even by eyes, by providing a lamp which luminesces in different colors depending upon the synchronous state between two logical timing signals formed in the same format. CONSTITUTION:On an omega navigation system, etc., reception-timing signal S4 is formed by a fixed format signal from each omega transmitting station, and internal timing signal S1 formed coincidentally with the transmission format from internal timing signal generator 2 at the receiver side is divided corresponding to respective transmitting stations, thereby forming signals S1a to S1h. Signal S1a to 1h  are connected to corresponding bicolor switching lamps 8A to 8H; when each signal is logic ''1'', the corresponding lamp is grounded and output Sr of power supply Vc with signal 4 turned into logic ''1'' and output Sg with turned into logic ''0'' are applied to red- light terminals and green-light terminals of respective lamps. Therefore, since lamps change from green into red or from red into green if signals S4 and S1 are asynchronous each other, their asynchronism can be confirmed clearly and the synchromism can be established by timing circuit 5.

Title: High frequency heating device
Inventor: OKUTSU TAKAHITO
IPC: H05B6/66
Filed: 1990-06-07
Abstract: PURPOSE:To improve the durability and reliability of a relay in putting a high frequency oscillator on and off by setting generation of a relay signal, an inverter on/off signal, and a power signal as specified. CONSTITUTION:When a user sets a menu, a relay signal generating part gets on by a control part 11, an inverter on/off signal generating part 12 gets on after than, and finally a power signal generating part 13 gets on finally. At this time, a current sent to a relay 9 flows after a contact voltage is stabilized. For putting a high frequency oscillator 4 off, the power signal generating part 13, inverter on/off signal generating part 12, and relay signal generating part 8 become off in this order. At this time, the relay 9 gets off with a delay of a predetermined time after outputting an off signal from the power signal generating part 13 In putting the high frequency oscillator 4 on/off, therefore, the current can be prevented from flowing through a contact while the contact voltage at the relay 9 is unstable, thereby the durability and reliability of the relay 9 can be improved.

IPC: B60T13/12
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To miniaturize a negative pressure booster by providing an auxiliary cylinder for supplying a liquid pressure from a high pressure source and pressing an assist piston toward a piston side. SOLUTION: After a brake operation is started, a brake depressing force FP applied to a brake pedal 12 is transmitted to a depressing force transmission piston 54. The brake depressing force FP transmitted to an assist piston 52 is transmitted to a second piston 26. Then, the brake depressing force FP is transmitted to a first piston 24 via a second spring 42. Further, a liquid pressure PM produced in a first liquid pressure generation chamber 28 is supplied as a brake liquid pressure to a first liquid pressure passage 72. Thus, if a brake liquid pressure booster 10 is in a normal state, a brake liquid pressure PM=FP/ SS is produced according to the brake depressing force F. Herein, SS is a sectional area of a small diameter part 22. Thus, a function of changing a boosting rate and the booster is miniaturized.

Title: High-resistance ground-fault accident detector
Inventor: MEYONNHO YU
IPC: G01R31/08
Filed: 1991-05-24
Abstract: PURPOSE: To detect steadily a high-resistance grounding fault in distribution lines in a multiple grounding or direct grounding method, by detecting an even- number harmonics in an arc current waveform and judging the high-resistance grounding fault when data related to the even-number harmonies is over a given level. CONSTITUTION: Using a failure detecting algorithm, even wave power in a formula 1 and odd wave power in a formula 2 are calculated from one-cyclic data stored in a memory means 100. Then, a ratio of the even wave power to the odd wave power is calculated, and a variation from even wave power to new even wave power in the next cycle is calculated. At each frequency, the ratio of the even power to the new even power and the variation of the even wave power are compared with each set level to detect the failure. When the set level for the failure is over these calculated data, the state is judged as a high-resistance grounding fault.

Filed: 1995-06-16
Abstract: PURPOSE: To prevent a bad copying of the height of a cutting nozzle due to a upward camber of a cut lug by cutting the lug a little longer in the longitudinal direction, cutting its short direction side at a reversely run and retreated position and successively cutting the longitudinal direction side again from the terminal position of the cutting path in the longitudinal direction. CONSTITUTION: In the case of cutting off lugs 2 consisting of 2a, 2b and 2c connecting with a steel sheet 1 in the longitudinal direction, cutting is performed in order of (1)-(7) along cutting paths (1), (2), (4), (5), (7) and a moving paths (3), (6) shown in a dot line (wherein cutting is not performed by the method such as a quick moving, etc., but a cutting torch only is moved.) In this case, the length up to each terminal position (qa) and (qb) of the cutting paths (1), (4) in the longitudinal direction are specified to be longer than a prescribed length (1a, 1b). By this method, since the height of the nozzle from the surface of the steel sheet is smoothly adjusted, a trouble such as the interruption during cutting is prevented and the cut surface of excellent quality is stably obtained.
