Title: Method and apparatus for real-time control of electromagnetic type oscillating body
Inventor: NAKAMURA HIROSHI
IPC: H04R3/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To control an electromagnetic type oscillating body at real-time to an input signal and to oscillate/control the oscillating body accurately by making it proportional correctly to the input signal. SOLUTION: A simulation circuit 2 for outputting a signal close to the free motion of an electromagnetic type oscillating body to an input signal is installed independent of a practical driving circuit. The simulation circuit 2 produces signals of acceleration, speed, and displacement corresponding to the free motion of the oscillating body from the input signal. In these signals, the mass, friction and distortion by spring force of the oscillating body are compensated/corrected by a compensation/correction operation level conversion circuit. The compensated/corrected signal is current-amplified and supplied to the coil of the oscillating body, and the oscillating body is made correctly proportional to the input signal at real-time to the input signal and oscillated.

Title: Logical simulation model generation system
Inventor: TOBINAGA SATOSHI
IPC: G06F17/50
Filed: 1991-05-31
Abstract: PURPOSE:To execute a logical operation once when the same logical operation exists in fan-in information of different logical variables so as to speed up logical simulation. CONSTITUTION:A connection information generation procedure 1 generates fan-in information and fan-out information for respective logical variables included in a logical circuit from the inputted logical circuit. A same logical operation extraction procedure 2 sequentially checks fine-in information for respective generated logical variables and retrieves whether the equal logical operation exists or not, whereby it outputs it. A temporary logical variable number setting procedure 3 sets the logical variable obtained in the extracted logical operation as the new temporary logical variable. A fan-in information alteration procedure 4 exchanges the original logical expression of the extracted logical operation with the temporary logical variable and alters fan-in information. A fan-out information alteration procedure 5 exchanges the original logical variable having extracted fan-in information with the temporary logical variable among fan-out information of the logical variable included in extracted fan-in information.

Title: Prime mover provided with rotary reciprocating piston
Inventor: TANIGAWA HIROYASU
IPC: F01B7/02
Filed: 1989-05-22
Abstract: PURPOSE:To improve turning torque by way of attempting effective use of exhaust steam by injecting low pressure steam to a turbine blade group through a nozzle group from an exhaust port group which opens with an opposed piston reciprocating by the guidance of a curved slot. CONSTITUTION:A piston 9 stored opposed in a main body 1 is rotated by a rotary axle 26 and reciprocates as a piston pin 10 is guided to a curved slot 13 dentedly provided on a curved slot cylinder 12. When a rotary valve 19 opens, steam is supplied to a high pressure chamber 2 through an air inlet 8. When the piston 9 reaches the neighborhood of a dead point, the rotary valve 19 closes and the exhaust port 4 opens. Then high pressure steam from the exhaust port 4 is injected to a turbine blade 7 through a nozzle 6 and a turbine blade wheel 14 is rotated. Consequently, as the turning torque of the turbine blade wheel 14 is transmitted to the main body 1 through gearings 16 - 18, it is possible to increase the turning torque of the main body 1. Accordingly, the main body 1 is rotated by using low pressure steam exhausted and it is possible to heighten energy efficiency.

Title: Coaxial relay control circuit
Inventor: IWASAKI HIROSHI
IPC: H04B1/44
Filed: 1985-06-13
Abstract: PURPOSE:To decrease damage to a relay and to extend the service life by using a slow release circuit and a detection circuit of transmission output so as to change over the coaxial relay while the transmission power is in a prescribed value or below. CONSTITUTION:In turning off a press-to-talk switch 1 from the on-state, after a prescribed time (e.g., several 10msec) elapses, '0' is fed to a logic circuit (e.g. OR circuit) 6. On the other hand, since a detection circuit 5 comprising diodes detects transmission power and outputs, e.g., '1' when the transmission output is a prescribed value or over and outputs '0' when below the prescribed value, '1' or '0' is fed to the OR circuit 6 depending on the transmission power. Since the relay 3 and the coaxial relay 4 are driven succeedingly when the transmission power is not less than the prescribed value (e.g., several tens watt), the transmission power is not interrupted by the coaxial relay. That is, when the transmitter is operated normally, the press-to-talk operation is attained and even if the transmitter is operated abnormally, the reception operation is selected with the transmission power reaches the prescribed value or below.
