Title: Controller for motor-driven vehicle
Inventor: ISHIDA YOSHINOBU
IPC: A61G5/04
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To increase driving force to a motor-driven vehicle without increasing the burden of an operator and to improve operability. SOLUTION: Operating force for a person to move the vehicle forward is detected by operating force detecting parts 20R and 20L, and controllers 12R and 12L of a motor-driven wheelchair are provided with control parts 18R and 18L for generating the driving force for compensating this detected operating force at motors 10R and 10L when this operating force reaches a set value. The control parts 18R and 18L calculate the change amount of driving force by subtracting the set value from the operating force. By adding this change amount to current driving force, new driving force is generated at the motors 10R and 10L.

Title: Method and device for correcting duty ratio
Inventor: TSUBAMOTO DAITA
IPC: H03K5/00
Filed: 1994-09-19
Abstract: PURPOSE: To suppress the invalidation of duty ratio of a clock due to varication in the characteristic of a transistor in an LSI chip and to improve reliability by correcting the invalidation of the duty ratio of a pulse generated in an electronic circuit. CONSTITUTION: A pulse sequence A inputted to a circuit 50 is converted into two pulse sequences BP, BN having mutnally reversed polarities by a buffer 51, and inputted to a duty ratio corrector 52. In the corrector 52, a pulse edge detecting means 53 detects either the rise or fall of each of the pulse sequences BP, BN, and a pulse sequence generating means 54 generates a pulse sequence C which perporms rise/fall of the pulse synchronously wiht the rise/fall of the pulse detected by the means 53. When the means 53 detects the rise/fall of the pulse sequences BP, BN, the mutually same waveforms with phases delayed each other by a prescribed quantity are found in the rise and fall of the pulse. Therefore, the invalidation of the duty ratio between the pulse sequences BP, BN generated in the buffer 51 can be corrected by the duty ratio corrector 52.

Abstract: PURPOSE:To decrease the bit shift occuring in the change in a duty or the fluctuation in a base line by detecting the time difference between a reading out signal and a clock signal according to the polarity of a reproduced analog signal, and controlling the threshold value of a comparator to minimize the time difference between both polarities. CONSTITUTION:A reading out signal (b) and a clock signal (c) are inverted by inverters 6, 7, and the reading out signal and clock signal of both polarities are supplied to D type FFs 8-15. Then the time pulse proportional to the time difference TER between the signal (b) and the center of the signal (c) at the rising polarity of the signal (a) is obtd. from the output (d) and the output (e), and a time difference signal (h) at the rising polarity is formed in an OR circuit 16. A time difference signal (i) is similarly formed. The differential signal (j) of both signals is then obtd. and is inputted as a threshold value voltage via an LPF19 to a compartor 3. If the threshold value voltage is higher than an optimum value, the pulse width on the negative side of the signal (j) is longer than the positive side TER and the negative voltage of the time difference is supplied to the comparator 3. The threshold voltage obtains a correct duty. The reading out following up the fluctuation in the base line of the signal (a) is performed by setting the breaking frequency of the LPF19 and an amplifier circuit 2.

Title: Amplitude correction circuit
Inventor: OCHIAI MASASHI
IPC: H04N3/23
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an amplitude correction circuit by which an amplitude is corrected without complicated component constant design by improving a circuit drift. SOLUTION: A/D-converted luminance and color difference signals 103, 109 are stored in a line memory circuit 128 and in the case of reading a stored signal, a read frequency by a read clock 124 is modulated in response to fluctuation in a high voltage detection signal from a high voltage detection circuit 116 and the digital signal readout by a read clock is D/A-converted to restore a signal into analog luminance and color difference signals thereby making correction so that a horizontal amplitude on a screen is made constant. Since an amplitude is corrected by modulating a video signal itself through digital processing, a circuit drift generated by a conventional analog correction is eliminated and a complicated analog circuit design is not required.

Title: Sand packing method for full-mold casting method
Inventor: HIROTSUKA TAKASHI
IPC: B22C9/04
Filed: 1985-10-08
Abstract: PURPOSE:To maintain a good sand packing state in a casting flask by embedding guide screens in molding sand in proximity to an expendable pattern in the stage of charging the dry molding sand to the pattern, thereby improving packing efficiency and eliminating sand flow on the surface of the pattern in the stage of applying fine oscillation thereto. CONSTITUTION:The expendable pattern A made of a foamed polystyrene is placed on the bottom laying dry molding sand 2 in the molding flask 1 of a full-mold casting method. The lower guide screen 5 having the mesh opening larger than the charged sand is embedded in a sand bed 3 in proximity to the lower aperture 4. The sand 2 is thoroughly packed into the lower aperture 4 when the dry molding sand 2 is charged into the flask. Another upper screen 5' is then embedded into the upper layer 3' of the already packed sand 2 by shifting the same from the screen 5 toward the flask 1 side and erecting the base part thereof. The sand 2 is charged into the flask in this state, then the sand on the pattern A side of the screen 5' is packed into the upper aperture 4' by the fluidity thereof and the slight oscillation of the flask 1; at the same time, the fluidity is suppressed by the screen 5', by which the packability is improved. The good sand packing condition is thus maintained in the flask 1.
