Title: Three phase magnet generator
Inventor: MORIMATSU MASAKI
IPC: H02K3/18
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To obtain a three phase magnet generator being driven through an internal combustion engine in which the size of a drive engine can be reduced by reducing drive torque, power generation efficiency can be enhanced by making smooth the output voltage waveform, a small sized or high output generator can be realized by reducing the self power generation or employing a high density coil, and the size and cost of a smoothing capacitor can be reduced by lowering the peak voltage. SOLUTION: The number of teeth of a stator wound with a power generation coil is set at 3m (m is a positive integer) and the number of poles of a permanent magnet secured to the rotor is set at 2n (n is a positive integer). The number of teeth 3m and the number of poles 2n are set such that 2n/m is not an integer so that the voltages induced in a plurality of tees forming the same phase voltage have the same polarity and a phase shift. Preferably, the permanent magnet secured to the rotor is a neodymium/iron/boron magnet. When the number of teeth is 3m, the coils are wound while arranging the polarity of voltage induced in each coil by reversing the winding direction such that coils of the same phase are continuous to m ties continuous in the circumferential direction of the status and each teeth corresponds to the polarity change of a facing permanent magnet.

Title: System clock supplying system
Inventor: SHIMIZU SHIGEKI
IPC: G06F1/04
Filed: 1986-12-03
Abstract: PURPOSE:To make the change of a numeric value on a program or the hardware constitution of a control circuit unnecessary by the clock of a CPU, by using another clock asynchronous with a CPU clock as the clock of the control circuit, and demultiplexing variably it with the program of the CPU. CONSTITUTION:The control circuit 2 is operated with the clock phiB asynchronous with the clock phiA of the CPU. Since the frequency of the clock phiB can be set by varying a demultiplex ratio from a source clock SCL by the CPU1 at a clock generator 5, the CPU1 can set the clock phiB at the time of power ON in spite of the phiA. Therefore, the clock phiB can be set constant invariably even when the frequency of the source clock SCL varies, and it is not necessary to change the hardware constitution of the control circuit 2, or data on the program of the CPU1.

Abstract: PURPOSE: To provide a switching power supply comprising a 2-diode half bridge by providing a magnetic coupling transformer where a choke coil is used as a primary winding, and converting AC voltage excited on the secondary side into DC, and superposing it onto a rectifying and smoothing line. CONSTITUTION: In a magnetic coupling transformer MCT, AC voltage in switching cycles is excited to the secondary winding N3 by a choke coil CH. This AC voltage is rectified and smoothed by a bridge rectifier circuit D3 and the rectifying and smoothing circuit of a voltage superposing capacitor C3 in a certain period, and Dc voltage V2 is generated across the voltage superposing capacitor C3 . This is connected is series to the smoothing capacitor Ci. Hereby, for the rectified and smoothed voltage Ei on the primary side of the switching power circuit, the one where DC voltage V2 across the voltage superposing capacitor C3 is superposed on the DC voltage Ei across the smoothing capacitor Ci is obtained. Accordingly, the switching power can be driven with high-voltage power without increasing the breakdown strength of the smoothing capacitor Ci.

Abstract: PURPOSE:To omit verification and to speed up programming by providing a dummy cell to each storage cell group to monitor the writing and erasing of any memory cell in the cell group. CONSTITUTION:When a high level address input is applied to a word line Wi or the like, memory cells Mi, j1-Mi, j3 or the like in a matrix array memory cell 1 are selected and a high level erasing pulse Ci is applied from an information writing/erasing means 4, the cells Mi, j1-Mi, j3 are erased.

Abstract: PURPOSE:To enlarge a pressure bearing area for oil lock by forming a space between the outside of a damper cylinder and an inner tube into an oil lock chamber, and thereby providing the outer circumference of a piston rod with an oil lock collar which is coupled in the oil lock chamber. CONSTITUTION:When an outer tube 1 is lowered down, a flow path from an oil chamber underneath an oil lock collar 43 to an oil storing chamber S3 is throttled while both of the tapered surface 44a of the outside member 44 and the tapered surface 51a of an inside member 51 of the oil lock collar 43 are being faced to the upper end circumferential surface of a damper cylinder 3. When the outer tube 1 is furthermore lowered down while the most compressed condition is resulted in, the inside member 51 of the oil lock collar 43 is coupled in the upper end outer circumferential surface of the damper cylinder 3. This thereby allows working oil within the oil chamber underneath the oil lock collar 43 to flow to the oil storing chamber S3 only through a minute gap between the inner circumferential surface of the inside member 51 and the upper end outer circumferential surface of the damper cylinder, thereby forming the whole of the oil chamber underneath the collar 43 into an oil lock chamber.
