Title: Device for estimating air-fuel ratio of engine
Inventor: MIWAKEICHI HIROSHI
IPC: F02D41/34
Filed: 1982-12-27
Abstract: PURPOSE:To estimate air-fuel ratio with a high accuracy, by detecting a phase difference from a signal obtained by a differential value of a rotation speed, which is similar to a practically generating torque, and an estimated value of the generating torque obtained by delaying a first-order lag signal of the reciprocal of the rotation speed. CONSTITUTION:A reciprocal 1/N of a rotation speed N is detected in a rotation speed N detecting circuit 101 from an ignition signal S1 fed from an ignition coil 12, and then a first-order lag signal (e) of the 1/N is generated by a first-order lag circuit 107 to be fed to a delay circuit 109. A delay signal (g) obtained by delaying the first-order lag signal (e) by the time corresponding to one rotation of an engine is outputted from the delay circuit 109 to a phase difference detecting circuit 110, in which phase difference upon on-operation of a throttle full closing switch 10 is detected from the delay signal (g) and a signal (h) of a differential value dN/dt of the rotation speed N inputted from a differentiating circuit 111 thereinto. According to the phase difference, air-fuel ratio is indicated in an indicating circuit 17 as deviation from the air-fuel ratio at a best torque point.

Title: Method for manufacturing compound semiconductor single crystal and its manufacturing apparatus
Inventor: NAKAMORI SHOJI
IPC: H01L21/20
Filed: 1994-09-22
Abstract: PURPOSE: To achieve stable crystal growth excellent in yield rate by enabling the temperature distribution adjustment within a furnace to be performed without manual operation, and enabling the temperature distribution with little distribution excellent in reproductivity to be made. CONSTITUTION: The temperature distribution within a high-temperature furnace 1 is measured with the thermocouple of a profiler 8. A personal computer 9 for control where measured temperature distribution is inputted determines the difference between the measured temperature distribution and the objective temperature distribution, and judges whether the difference is in the tolerable range or not. When the difference is not within the tolerable range, the personal computer 9 for control operates the temperature distribution modification data proportionate to the difference. It controls a temperature adjuster 6, according to this operated temperature distribution modification data. The temperature distribution adjusted by this control is measured again, and the control is repeated until the measured temperature distribution becomes the objective temperature distribution.  This way, the temperature distribution of a hightemperature furnace is controlled to an objective value.
