Title: Logical equivalent verifying method
Inventor: TANDAI MIYAKO
IPC: G06F17/50
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To correctly perform logical equivalent verification between two logic circuits even when logical optimization is performed over FFs(flip-flop) including a series of FFs constituting a loop. SOLUTION: Two object logic circuits 1 and 2 of logical equivalent verification are inputted from logic circuit files 120 and 121 and the FFs included in the logic circuits 1 and 2 are made to correspond to each other. When there is an FF which does not correspond, a logic inequaity between the logic circuits 1 and 2 is outputted. When all the FFs can be made to correspond to each other, a logic comparison is made as to all cone couples obtained by decomposing the combinational circuit surrounded with the input/output edges of the logic circuits 1 and 2 and the FFs. When all the cone couples have matching logic, the logic matching between the logic circuits 1 and 2 is outputted. If there are a logic-mismatching cone couple, polarity propagation is assumed for a polarity propagation candidate FF couple and a logic comparison of the cone couple is made.  When it is decided that all the cone couples have matching logic, the logic matching between the logic circuits 1 and 2 is outputted and when there is a cone couple having mismatching logic, logic inequality between the logic circuits 1 and 2 is outputted.

IPC: F15B11/00
Filed: 1989-05-19
Abstract: PURPOSE:To contrive to effectuate smooth shock-relieving and to save pump operating power by reducing rate of supply and return of pressurized oil to and from a hydraulic cylinder at a time when a piston approaches the end of its stroke, and by also reducing discharge rate of a hydraulic pump. CONSTITUTION:By operation of a remote control valve, a directional control valve 24 is put in operation through pilot oil passages 35, 36 and 37, and a piston 22 approaches the end of its stroke. Then a proximity switch 23 is put in operation and a solenoid valve 38 is opened thereby, making the oil passage 35 communicate with an oil tank 30 through the valve 38 and a pressure reduc ing valve 40. Then the pilot pressure of the valve 24 falls, resulting in decrease of movement of a spool of the valve 24, and rate of supply and return of pressu rized oil to and from a hydraulic cylinder 21 decreases thereby. Then negative concrete pressure raised at return passage acts on a regulator 43 and discharge rate of a hydraulic pump 42 decreases thereby too. With the above-mentioned arrangement, shock at the end of piston stroke can be smoothly relieved and, at the same time, wasteful use of pump operating power can be eliminated.

Title: Measuring device for signal
Inventor: ISHII YASUSHI
IPC: G01R19/00
Filed: 1979-10-05
Abstract: PURPOSE: To measure the size of a modulated minute signal by a method wherein a mutual correlation function between a detection signal and a prescribed reference signal is determined and further the difference between the values in the upper and lower flat parts of the correlation function is determined.  
     CONSTITUTION: A modulated signal m (t) is generated by a modulated-signal generator 7 and, through the intermediary of a modulator 2, the signal modulated intermittently is generated as a sound. This sound of signal reaches a measuring point, is collected and detected together with background noises by a microphone 8, and is turned to be a signal S (t) indicating the volume of sound at the measuring point through the intermediate of an amplifier 9, etc. The sound of signal is attenuated in the course of propagation from the source of sound to the measuring point and turns to be small in such a degree that it can hardly be discriminated from the background sounds. Here, the correlation function ϕ rs  (r) between the signal S (t) indicating the volume of the sound and the reference signal r (t) having the same frequencies with those of the modulated signal is found. The difference between the values of the upper and lower flat parts of the above correlation function is proportional to the difference in the level of sound. By such a constitution, the volume of the test sound at the measuring point can be determined with excellent accuracy.

Filed: 1984-06-22
Abstract: PURPOSE:To receive a lot of image data with a comparatively small capacity of a buffer memory by using alternately two buffer memories, applying expansion processing to the data every time one memory is occupied and transferring it to a pattern memory. CONSTITUTION:A compression data discriminating section 10 checks whether or not data is subjected to compression when a delivery control section 9 transmits the data to a data expanding section 11 from an image data buffer and informs the result. When the data stored in an image data buffer 3 is all transmitted to a pattern buffer 13 and the buffer is idle, while an input data is filled in an image data buffer 4 and ''1'' is set to a flag 8, the delivery control section 9 starts transmitting the data in the buffer 4 to the expanding section 11. When the data input from the host is continued, the system controls it that the data is received again in the buffer 3. The expanding processing of data is executed and the result is displayed while the data is received by using alternately the buffers 3 and 4.
