Title: Inverter-driven air conditioner
Inventor: MORI MASATO
IPC: F24F11/02
Filed: 1993-12-09
Abstract: PURPOSE:To enable simplification of a control program and execution of high-speed response to a change in a load without excess and deficiency of a torque by computing an output voltage command value from a current component and an output frequency command value in conformity with a functional relationship set beforehand. CONSTITUTION:Phase currents of a compressor motor 9 are detected by current detectors 1a and 1b and transformed into a current (id) for excitation and a current (iq) for a torque of an orthogonal coordinate system by a coordinate transformer 2 by using an angle of rotation of coordinates obtained from a coordinate rotating unit 5. A voltage command value computing means 3 computes voltage command values (vd) and (vq) from the current (id) for excitation, the current (iq) for the torque and an execution frequency omega1. Next, these voltage command values (vd) and (vq) are subjected to inverse transformation into output voltage values (vu), (vv) and (vw) on three-phase coordinate axes by a coordinate transformer 4. These values are transformed into pseudo sine wave alternating currents of three phases by switching control of a power inverse conversion unit 8 through a PWM signal generator 6 and thereby the compressor motor 9 is driven. According to this constitution, a control program for processing data on a power factor is dispensed with and the speed of a control response can be made high.

Title: Method for connecting rolled stock
Inventor: MASUDA AKIHEI
IPC: B21B15/00
Filed: 1991-11-25
Abstract: PURPOSE:To easily connect preceding rolled stock and succeeding rolled stock by forming projecting parts on either of the rear end of the preceding rolled stock or the front end of the succeeding rolled stock, forming recessed parts in the corresponding positions of the other and advancing the projecting parts into the recessed parts, thereby crushing and bulging the projecting parts. CONSTITUTION:A proper working device moving together with a hot rolling line is provided. The projecting parts 11 are formed on either of the rear end 1 of the preceding rolled stock and the front end 2 of the succeeding rolled stock and the recessed parts 12 are formed in the corresponding positions of the other by this device. The succeeding stock 2 is made to follow up the preceding stock 1 to advance the projecting parts 11 into the recessed parts 12. The projecting parts 11 are crushed and bulged by the pressing device moving at the same speed as the speed of the rolled stock. As a result, the projecting parts and the recessed parts are indisconnectably engaged and the preceding stock and the succeeding stock are connected. The registration is easier than the conventional methods and the shape dimensional accuracy of the projecting parts and the recessed parts is not so much required.

Filed: 1994-12-14
Abstract: PURPOSE: To shorten transaction time by executing the receipt of money or the transfer transaction of an amount of money corresponding to a coin below, e.g. 1,000yen by a prepaid card. CONSTITUTION: A customer, etc., inserts a cash card C into a cash card reader/ writer 5, and inserts the prepaid card P into a prepaid card reader/writer 10. Then, the receipt and the transfer transaction are executed in such a way that the receipt and the transfer transaction of the money over, e.g. 1,000yen are received and transferred from a paper money receiving and paying part 9 by paper money, and the receipt and the transfer of the money below, e.g. 1,000yen are assigned from the prepaid card P, and an assigned portion is subtracted by the prepaid card reader/writer 10.  Since the receipt and the transfer of the money below 1,000yen are executed by the prepaid card P, and the receipt and the transfer transaction by the coins are not executed, the transaction time can be shortened compared with the case of the past where the receipt and the transfer transaction by the coins are executed.

IPC: F02D41/06
Filed: 1987-12-08
Abstract: PURPOSE:To prevent the occurrence of an engine stole, by a method wherein, at a time when increasing after starting is effected after the starting of an engine, when the time is within a given time starting from a time after the starting of an engine or the rotation speed of an engine is below a given value after the starting of an engine, a decrease of fuel responding to a change amount of an intake air amount is prohibited. CONSTITUTION:During running of an internal combustion engine, a control circuit 45 computes a fundamental fuel injection amount based on an intake air amount by an airflow meter 12 and the number of revolutions of an engine determined by a rotary angle sensor 48. Variation of a fundamental fuel injection amount is corrected according to a change amount of an intake air amount per unit rotation of an engine. In this case, after the starting of an engine, it is decided whether an increase after starting to increase a fuel injection amount after the starting of an engine is effected. At a time when it is decided that an increase after starting is effected, when the time is within a given time starting from a time after the starting of an engine or the rotation speed of an engine is below a given value, a decrease responding to the change amount is prohibited, and this method prevents the occurrence of poor starting and an engine stole.

Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To convert the voice information of a narrow frequency band to that of a wide frequency band with a small, simple and inexpensive circuit structure. SOLUTION: In a trapezoidal waveform generating circuit 41, voice data is compared for each sample, the top peak and the under peak are detected based on the comparison output, a sample point having one sample period before and after each peak is detected, and the level of these sample points is set. In addition, among the adjacent peaks, the trailing one sample point in the timewise pre-peak is connected, with a line segment, to the preceding one sample point in the timewise post-peak, and nearly trapezoidal waveform data is formed from that segment. Then, a higher harmonic component is extracted with a high pass filter 42 from this trapezoidal waveform data, and is added to the original voice data with an adder 13.  Thus, the voice data of a wide frequency band can be formed, in which the higher harmonic component is added to the original voice data, by the small, simple and inexpensive circuit structure.
