Title: Motor controller
Inventor: OGAWA MITSURU
IPC: H02P7/03
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To obtain a motor controller which can decide failure occurring on a passage for switching the conducting direction of a power supply to a motor. SOLUTION: Relay switches 50, 60 switch conduction of a power supply and a DC motor M between one and the other directions. A microcomputer 110 switches the current direction of the relay switches 50, 60 and decides that the relay switch 50, 60 is faulty if the terminal voltage data of the DC motor M to the input terminals IN1, IN2 thereof does not correspond to the conduction stop state to the DC motor M. When a decision is made that the relay switch 50, 60 is faulty, power supply to the DC motor M is interrupted thus stopping abnormal heating of the DC motor M without employing a thermal protection sensor in the DC motor M.

Title: Growing device for ribbon crystal
Inventor: NAGAMI KEIMEI
IPC: C30B15/20
Filed: 1981-07-14
Abstract: PURPOSE:To grow a ribbon single crystal free from crystal defects by measuring the temp. near the surface of the grown crystal including the part near the interface of solid-liquid phase in a vessel, and controlling the same in such a way that the temp. gradient in a prescribed atmosphere including the part near the interface is kept constant. CONSTITUTION:If a main heater 11 is heated to melt the raw material in a crucible 9 by the high frequency electric power from a high frequency power source 12, a melt 10 ascends in the slit provided to a die 8. In this state, the seed crystal fitted to a taking up shaft 3 is brought into contact with the melt 10 at the top end of the die 8 and a ribbon crystal 6 is taken up upward at a prescribed speed by a taking up mechanism 2. As the ribbon crystal 6 grows, a temp. gradient changes and therefore this change is detected with a temp. detector 7 disposed in extreme proximity to the grown crystal including the part near the solid-liquid interface. According to the signal of a voltmeter 13, a control circuit 14 controls electric power supplies 5, 12 for high frequency heating which control the electric power to be supplied to the main heater 11 and an after heater 4, thereby controlling the atmosphere temp. and maintaining the constant temp. gradient.

Title: Prefetch control system
Inventor: HIROSE MOTOYOSHI
IPC: G06F9/38
Filed: 1989-04-28
Abstract: PURPOSE:To improve the system throughput by suppressing or canceling the accepted prefetch request when a comparison means decides that the bank busy frequency is higher than a threshold level. CONSTITUTION:In prefetch control system, the instructions and data are prefetched from a bank-divided memory 3 to a buffer memory 10 with a prefetch request given from a processor 1. A detection means 24 is added to the system to detect the bank busy frequency of the memory 3 together with a comparison means 25 which compares the detected bank busy frequency with a prescribed threshold level. When the availability of the memory 3 is increased by the prefetch request, the accepted prefetch request is suppressed to be kept waiting for a fixed time until the availability of the memory 3 is reduced or to be canceled. Thus the availability of the memory 3 for prefetch is suppressed. As a result, the system throughput is improved in the prefetch control system.
