Title: Count-check type detector for angle of rotation
Inventor: NAGAHAMA TAKAHIDE
IPC: G01D5/245
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the accumulation of count errors by a method wherein a count value of a pulse signal for detecting a rotation angle is subjected to division, the residual is calculated and compared with a value set beforehand, and whether a counter value is normal is checked up on the basis of the result of the comparison. CONSTITUTION:During the detection of a rotation angle, a count value of a pulse counter 6 is divided by a prescribed pulse number by a divider 8 and the residual is calculated every time when a Z-pulse signal from a pulse encoder 3 is outputted. When there is no count error, a count value obtained by counting in the counter 6 is due to be integral times as large as the prescribed pulse number, and the residual of the calculation should be zero. When there is the count error, however, the residual of calculation is a value other than zero. Accordingly, the residual produced in calculation by the divider 8 is compared in a comparator 9 with a value set by a setting unit 9a, and based on the difference between them, the result of the decision as to whether the counter value is normal is outputted from a decision unit 10.

Title: Semiconductor device
Inventor: YAMAZAKI AKIRA
IPC: H01L21/331
Filed: 1990-03-26
Abstract: PURPOSE:To accurately grasp the temperature rise of a transistor, and protect the transistor from the destruction caused by thermal runaway, by forming a transistor and a resistor region for temperature detection on the same semiconductor substrate. CONSTITUTION:A base region 2 having a conductivity type opposite to a collector region 1, and a resistor region 4 for temperature detection are formed inside the collector region 1. An emitter region 3 having the same conductivity type as the collector region 1 is formed inside the base region 2, and the following are formed in the respective regions: a base electrode 5, an emitter electrode 6, a resistor electrode 7, and a collector electrode 8. When a transistor is operated and the temperature of a semiconductor substrate rises, the temperature of the resistor region also rises almost similarly, and the resistance value changes. Hence the temperature rise of the transistor can be accurately grasped by detecting the change of the resistance value. By cutting off the supply of base current before the transistor is damaged by thermal runaway, the transistor can be protected.
