Patent JP-H08251915-A (JP)
Title: Switching regulator
Inventor: YOSHIHARA TAKAO
IPC: H02H3/20
Filed: 1995-03-15
Abstract: PURPOSE: To protect a load circuit surely against overvoltage regardless of the load conditions by simplifying the circuitry pertaining to the overvoltage protective function. CONSTITUTION: When an overvoltage detection circuit 8 detects an output voltage from a regulator exceeding an overvoltage detection level, oscillation of a pulse width control circuit 6 is interrupted forcibly with a predetermined time lag being set by an overvoltage detection lag circuit 9 and a latch circuit 10. If the duty ratio of switching pulse is suppressed by a pulse width regulation circuit 11 during that interval, abnormal increase of overvoltage is suppressed and the oscillation is interrupted while lowering the output voltage gradually.

Title: High frequency heating device
Inventor: HISHIYAMA KOJI
IPC: H02M3/28
Filed: 1990-03-07
Abstract: PURPOSE:To suppress a voltage of a semiconductor switching element so as to obtain a high frequency heating device of high reliability by constituting a driving circuit of a constant current circuit, and raising driving of the semiconductor switching element gradually from the driving start. CONSTITUTION:A driving circuit 7 is connected to a base of a semiconductor switching element 5 constituting an inverter circuit 6, and the driving circuit 7 is composed of a constant current circuit 71 and a drive circuit 72. Due to gradual extension of ON-time of the semiconductor switching element 5 by means of the constant current circuit 71, a secondary side voltage e2 of a transformer 3 becomes a sinusoidal wave state when a magnetron is in an unstable state so that a voltage doubler circuit is inoperative, and in a stable oscillating state approaches a nearly square wave by means of a half-wave voltage doubler circuit. Namely, when an ON-width of the semiconductor switching element 5 is set small at the driving start, the voltage can be restrained at a low value. Consequently, the voltage of the semiconductor switching element 5 can be suppressed and a high frequency heating device of high reliability can be obtained.

IPC: G06F9/318
Filed: 1990-03-08
Abstract: PURPOSE:To enable a multifunction instruction without increasing the length of an instruction code by defining the meaning of added bits in the instruction code as processing contents set to a register and executing the multifunction instruction. CONSTITUTION:An instruction format is composed of an instruction code 11, added bits 12 and operand 13 and normally, the size of the added bit 12 is one bit. Thus, since the size of the instruction code adds one bit to the size of the instruction code 11 and the increase of the instruction code 11 is suppressed at one bit even when realizing the multifunction instruction, the hardware burden of an instruction prefetch part or the like is suppressed at a minimum as well and there is no influence onto the throughout of a ROM. Further, a pipe-line processing is not distorted by the difference of the instruction code size.

Title: Motor control circuit
Inventor: KANBE YUKIHIKO
IPC: H02P5/00
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To control a plurality of motors individually by a single motor controller by a method wherein a phase which is to be the excited phase of a motor is indicated to the driving circuit of the motor and selected in accordance with the count finish signal of the phase change time of the excited phase of the driving motor. SOLUTION: A phase change time is set in a timer register 21 and the phase change time is counted by a counter 22. If the count is finished, the counter 22 outputs a count finish signal and, at the same time, outputs an interrupt signal to a CPU. Phase shifters 24-26 shift the data in accordance with the count finish signal from the counter 22 and indicate to respective motor drivers that the excited phases of the respective motors are to be switched to the phases to be excited next. Further, a control register 23 controls the counter 22 by permitting or prohibiting the reception of the phase change time, the count start and the data shifting of the respective phase shifters 24-26. As a result, a plurality of motors can be controlled by a single motor control circuit.
