Patent JP-H01164054-A (JP)
Title: Integrated circuit
Inventor: YAMAZAKI MINEO
IPC: H01L23/50
Filed: 1987-12-21
Abstract: PURPOSE:To prevent a crack of a resin from being caused and to enhance thermal resistance during a soldering operation without a bending process by a method wherein a lead frame is shaped so as to disperse a stress. CONSTITUTION:Slits A are formed in a face opposite to a chip-mounting face of a lead frame 5. Because the slits A are formed, the length of the lead frame 5 can be regarded as a size l which is partitioned by the slits A. Accordingly, a stress which is concentrated on an end of the lead frame is dispersed to individual parts partitioned by the slits A; the stress in each partitioned part is proportional to the square of the length of the lead frame and is reduced sharply. At the same time, the slits A are filled with a resin; the thickness of the resin is made partially thick; a crack of the resin is hardly caused.

Title: Protective monitor for motor
Inventor: MORITA SHIZUNORI
IPC: H02P29/60
Filed: 1987-12-21
Abstract: PURPOSE:To enable the optimum protective monitoring of the winding temperature of a motor to be executed, by comparing a computed current value and an actual current value with each other, and an estimated temperature rise value and an actual temperature rise value with each other, respectively, by discriminating whether the respective values are within proper ranges or not. CONSTITUTION:By a protective monitor 21, from the output torque and rotational frequency of a motor 11, output is found, and by the output and the terminal voltage of the motor, a current value is computed. Then, the computed current value and an actual current value are compared with each other and when the values are out of an error range, it is discriminated whether the actual temperature rise value of the motor 11 is within the allowable value of a motor winding or not. When the value is equal to or more than the allowable value, the motor 11 is stopped. When the value is equal to or less than the allowable value, a temperature rise value is computed based on the computed current value or the actual current value. Besides, when an estimated temperature rise value is equal to or more than the allowable temperature range of the motor 11 and the actual temperature rise value is equal to or more than the allowable value, then the motor 11 is stopped.

Filed: 1989-12-13
Abstract: PURPOSE:To surely stop the charge/discharge of a capacitor when a transistor is turned off by turning off both two transistors at an input side and two transistors at an output side when a switching element is turned off. CONSTITUTION:When a charge pump control signal is set at an 'L' level, the transistor 32 is turned off. Then, the voltage of a power source V is applied to the emitter of the transistor 4 on one side of the input side, and the ground voltage to the emitter of the transistor 5 on the other side, and both two transistors 4, 5 are turned off. Therefore, the transistors 10, 11 at the output side are turned off, then, the charge/discharge on the capacitor 15 is stopped. At such a case, when a charge pump circuit is turned off, all the transistors 4, 5, 10, 11, 34, and 35 are turned off, which saves wasteful power consumption. Also, the transistors 10, 11 are surely turned off, which surely stops the charge/ discharge of the capacitor 15.
