Title: Composite roll bearing
Inventor: MORIMOTO MASARU
IPC: F16C19/49
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To prevent the tilting of a cylinder axial line by arranging a cylinder and a pair of balls arranged in contact to both end surfaces thereof on the same axial line. SOLUTION: A holder 5 is interposed between a bush 4 and a roller 6 fitted onto it, and a rolling body fitted to the window hole of the holder 5 consists of a composite rolling body consisting of a cylinder 7 and a pair of balls 8A, B making contact with both the end surfaces thereof. The centers of the cylinder 7 and the balls 8A, B are arranged on the same axial line. The bush 4 is an inner ring, and the roller 6 is an outer ring. Since a bias load P, when it acts on the left side of the roller 6, is held by the ball 8A without acting on the left end part of the cylinder 7, the axial line of the cylinder 7 is never inclined, and the cylinder 7 is smoothly rolled without inclining the rotating axial line since the ball 8A which received the bias load P has a spherical form which never causing the inclination.

Title: Semiconductor photodetector
Inventor: ISHIHARA HISAHIRO
IPC: H01L31/10
Filed: 1987-09-25
Abstract: PURPOSE:To form a pin-PD having high speed responding characteristic by providing a semiconductor multilayer film structure containing an optical absorption layer and a window layer on the surface of a semi-insulating semiconductor substrate, and growing as well the optical absorption layer on the rear face of a semiconductor substrate. CONSTITUTION:An N-type InP buffer layer 2, an n<-> type InGaAs optical absorption layer 3 and an n-type InP window layer 4 are continuously grown by a vapor growing method on a semi-insulating InP substrate 1, and a second n<-> type InGaAs optical absorption layer 6 is further formed on the rear face of the substrate. The original layer 3 is reduced in thickness to approx. 1mum by shortening a carrier running time. The layer 6 formed on the rear face has a thickness of approx. 3mum to completely absorb the transmitted light and not to return the randomly reflected light again to the front face side. Since optically excited carrier generated in the layer 6 is electrically isolated by the substrate 1 from the front surface element, it does not contribute to a photocurrent. Since diffusion current component due to the random reflection on the rear face of the substrate can be completely suppressed in this manner, high speed responding characteristic determined by the carrier running time and CR time constant of the original pin-PD is improved.

Title: Motor controller
Inventor: MISUMI HIROYOSHI
IPC: H02P29/00
Filed: 1990-09-13
Abstract: PURPOSE:To increase an interval of an interrupt generated in a controller and to eliminate a motor control mistake due to a calculating time in the controller by dividing in frequency an FG signal for controlling the motor when an ID signal is read by the controller to increase the time interval. CONSTITUTION:A switch 202 selects a signal divided by two from an FG signal in a state an ID is modulated, and the divided signal is input to an edge detector 203 to be similarly operated to be traced thereafter. In this case, if a controller 27 generates an interrupt, it reads a counted value of a latch circuit 205, and calculates when the FG signal is divided in frequency by two based on the read counted value, and sends the calculated result to a motor driver through a D/A converter to control a motor 33. Thus, when the ID signal is read, an interval of generating the interrupt of the controller 27 can be set to a longer value than that of normal state in which the ID signal is not read.

Title: Operation control method for hydroelectric power plant
Inventor: MUNAKATA KENJI
IPC: H02P9/04
Filed: 1985-10-30
Abstract: PURPOSE:To make it possible quickly to change over from power generation to the phase modification and vice versa by providing a clutch to connect the runner with and to disconnect it from the generator. CONSTITUTION:When a generator 10 is performed a phase modification with a clutch 16 disconnected, a governor 13 increases the speed of a runner 1 by carrying out an open control of a guide vane 5 is the power generation command is given. A speed comparator 11 connects the clutch 16, if the speed of the generator 10 coincides with that of the runner 1. Then a phase modification command is given, the governor 13 performs a close control of the guide vane 5. If the guide vane 5 is contracted to the no-load opening, it disconnects the clutch 16 and the generator 10 performs the phase modification for itself. Thus the generator 10 performs the phase modification for itself. Thus the water level depresser and exhauster become unnecessary.

Title: Oil-burner burning method
Inventor: YOSHINARI YUUJI
IPC: F23N5/24
Filed: 1983-12-20
Abstract: PURPOSE:To prevent the danger after burning is stopped, by detecting the remaining flame in a combustion chamber by a flame detector after the burning is stopped, and performing post purge during the time the remaining flame is detected. CONSTITUTION:In an oil burner provided with a post purge function, the remaining flame in a combustion chamber is detected by a flame detector after the burning is stopped. During the period from the time when burning is stopped to the time when the detection of the remaining flame is finished and to the specified time post purge is performed. Namely the period from the time when a vapor pressure switch is closed and a fan motor is started to the time when a burning solenoid valve is opened is a prepurge period A. An igniting transformer is conducted for a specified time period when the prepurge is finished and the solenoid valve is opened. When the burning is started by the operations of the igniting transformer and the solenoid valve, the flame in a furnace is detected by a flame detector. The period from the time when the vapor pressure switch is opened and the burning solenoid valve is closed to the time when the fan motor is stopped is a post purge period (C+D). The fan motor is operated during the flame remaining period C, which is detected by the flame detector, and a preset period D following the elapse of the period C, after the burning solenoid valve is closed (i.e. after the burning is stopped).

Title: Phase locked loop circuit
Inventor: KAWASAKI TAKESHI
IPC: H03L7/081
Filed: 1988-09-27
Abstract: PURPOSE:To attain a high speed lock-in even against a rapid phase change by feeding back the output of a voltage controlled oscillator to a phase comparator via a delay circuit whose delay time is controlled by an output voltage of an LPF. CONSTITUTION:When a reference clock 12 is switched into a read data 11 by a select signal, the frequency change is less but the phase is discontinuous, and a maximum 2pi[rad] of phase difference is caused. For example, if the data 11 is led in the phase, an output voltage 16 of the LPF 3 is changed in response to the phase difference, the frequency of the voltage controlled oscillator 7 is increased to start the correction of the phase shift. On the other hand, the delay of a delay circuit 8 is corrected by the voltage 16 to reduce the delay and the phase of a feedback signal 15 to a frequency phase comparator 2 is led further. Thus, when the clock 12 is switched to the data 11, the shift in the lead phase to be caused is corrected more acceleratingly than the feedback of an output signal 17 of the oscillator 7 to a comparator 2 simply.
