Title: Programmable logical device
Inventor: OKAWA TOSHIMITSU
IPC: G06F7/00
Filed: 1991-02-28
Abstract: PURPOSE:To attain programming in a system using only a 5V power supply and to enhance the usefulness by providing a control function on a high voltage power supply for writing the program. CONSTITUTION:A boosting circuit 3 boosts a 5V input to 20V based on the clock of a ring oscillator OSC 1. A multiplexer 20 gives a 20V to a W-gate controller 5 since the input is less than 20V and it represents no signal from a detector 2. An address decoder 6 designates the address of a memory cell 7 based on a serial address signal. A program by a serial data signal SDATA synchronously with a shift clock SCLK is given to the controller 5 and stored in a built-in shift register. The information SDATA is fed to the memory cell 7. A strobe signal NSTB is given to the controller 5 at the end of one unit of input of program information and one unit input is written to the prescribed address of the memory cell. By such constitution, the programming is optionally attained in the state of on-board or before or after the on-board.

Title: Pole change type rotary electric machine
Inventor: WATANABE TAKAHARU
IPC: H02K17/14
Filed: 1987-02-19
Abstract: PURPOSE:To reduce an interlayer insulator in a slot and to improve the productivity of a pole change type rotary electric machine by setting the number (q) of slots per high speed one pole of an armature winding to q=A+1/1(where A: even number), and composing one phase high speed poles of the number (A/2+1) of coils and the sets of the number of the coils of A/2. CONSTITUTION:In a 4/8 pole change type 3-phase induction motor, as shown, the number of slots is 30 and q=2+1/2. Each coil group consists of a set of an outer coil of 5 of coil pitch and an inner coil of 3 of coil pitch concentrically disposed, and a set of only a coil of 4 of coil pitch. Accordingly, a section to become a single layer winding contained at one coil side in each slot and a section to become a double-layer winding are formed. Then, the single-layer winding is increased to reduce an interlayer insulator in a lot. Further, since only the number of the coils of 3/5 may be sufficient, the steps of incorporating the coils in the slots can be largely alleviated, thereby improving the productivity.

Abstract: PURPOSE:To avoid malfunction due to hazard caused at an address change point by applying logic operation to output signals of a 1st latch circuit latched based on an advance clock of a write address data and a 2nd latch circuit latched based on an advance clock of a readout address data. CONSTITUTION:EX-OR 111-113 compare write address data WAi and readout address data RAi with corresponding bits and send a signal of the result of comparison to a NOR gate 12. The NOR gate 12 when 3 inputs are all at an L level gives an H level signal and in other cases gives an L level signal to a data terminal D of 1st and 2nd latch circuits D-FF 131 and 132. The D-FF 131 latches an output signal of the NOR gate 12 by an inverted write clock signal WCLK and the D-FF 132 latches the output signal of the NOR gate 12 by an inverted readout clock signal RCLK. The output signals of the D-FF 131 and 132 are led to an AD gate 14, where they are ANDed. Since the latch clock of the D-FF 131 and 132 is asynchronous, no hazard exists in the same timing.

Abstract: PURPOSE:To increase the breakdown voltage of an element, and to prevent the short circuit of an electrode and disconnections by etching a resistor in a tapered manner. CONSTITUTION:One conductivity type semiconductor substrate 1, a first insulating film 2 consisting of silicon oxide, etc. formed onto the semiconductor substrate 1 through a thermal oxidation method, a CVD method or the like, and a resistor 3 composed of polysilicon shaped onto the first insulating film 2 through the CVD method, etc. and etched in an tapered manner are formed.
