Title: Drive control circuit for brushless motor
Inventor: NAITO HAYATO
IPC: H02P6/06
Filed: 1988-02-23
Abstract: PURPOSE:To simplify a circuit configuration by providing a rotor magnet, 2-phase driving coils, a position detector, a power calculator and control means, and providing calculating means between the detector and the control means. CONSTITUTION:A drive controller for a brushless motor supplies a constant current from a DC power source 20 to Hall elements 2-4, and feeds back calculating means (Hall amplifiers) 8-10 having multiplying function nearest control means 17 from an amplifier 19. The current is supplied from the power source 20 through resistors 37, 38 to the elements 2-4 to generate magnetic fields phiu-phiw by a rotor magnet 1 and an output proportional to the current from the power source 20. This output is output to output amplifiers 11-13, and to square calculators 14-16, and the bias currents of the amplifiers 8-10 are controlled proportionally to the output of an amplifier 19. The amplifiers 8-10 are fed back with the output of the amplifier 19 so that its offset becomes proportional thereto. As a result, its torque ripple can be suppressed to 1/2 of a conventional one.

Title: Controlling method for combustion of boiler
Inventor: TASAKA EIJI
IPC: F23N5/14
Filed: 1993-02-03
Abstract: PURPOSE:To improve follow-up characteristics for fluctuations in loads by a method wherein, while a boiler is standing by, a falling gradient of hot water temperatures of boiler is computed and if it is predicted that temperatures of hot water may become lower than a set value within a predetermined time, prepurge is started, and if it is judged that temperatures of hot water may not become lower than a specific value within a specific time, prepurge is stopped. CONSTITUTION:Operation and stopping of a burner 3 is controlled by a combustion control device 4 based on a sensed value T of a sensor 2 for sensing hot water temperature of boiler. That is, when a sensed value T has risen to a set value TOFF, a stop signal is outputted to the burner 3 and a falling gradient of sensed value T, while a boiler is standing by, is computed and if it is predicted that the value T may become lower than a set value TON, a prepurge start signal is outputted. And if it is judged that the value T may not become lower than the set value TON within a specific time during the action of prepurge, a prepurge stop signal is outputted. As a result, useless starting and stopping of boiler can be avoided.

SOLUTION: In measuring the emission current of elements of (m, n) of multiple electron sources composed of wiring multiple cold-cathode elements into a matrix form, respective wirings in each row direction and each column direction are set to the ground level while an acceleration voltage is applied to a high-voltage electrode, and a current Is flowing through the high-voltage electrode is measured with no electrons emitted from the multiple cold-cathode elements in S1, and a current Ie' flowing through the high-voltage electrode is measured by driving the elements of (m, n) in S2. Provided that a spacer is not connected to the wire in the row direction of the row (m), Ie'-Is in regarded as the emission current in S3, S4.  Provided that the spacer is connected to the wiring in the row direction of the row (m), the high- voltage electrode is set to a ground level, a drive voltage is applied only to the wire in the row direction of the row (m), so that a current Isd flowing through the high- voltage electrode is measured, and Ie'-Is-Isd is regarded as the emission current in S3-S6.

Abstract: PURPOSE: To provide efficient lubrication by directing a lubricating oil to over an input shaft through an oil passage formed in a power take-up device casing and feeding the oil from up to two bearings through a pipe piercing through a fork.  
     CONSTITUTION: When no power is taken up, the lubricating oil fed from an oil collection gutter 1a to over the end of an input shaft 4 through holes 1b, 20a, 20b, and 20c flows into a pipe 24; a major portion of the oil is fed to a bearing 18 through a hole 24d, and the remainder is fed to a bearing 19 through a notch 24e at the other end of the pipe 24. When power is taken up the hole 24d is closed by a sleeve 25 so that the whole of the lubricating oil flowing into the pipe 24 is fed to the bearing 19. The hole 24d is thus closed or opened according as power is taken up or not so as to feed the oil to the bearing or bearings which need lubrication. Thus small amount of lubricating oil is used for effective lubrication.

The frequency setter 130 is set at a value where the frequency of a voltage phase signal theta*IS as the output signal of a counter 116 is conformed approximately to the frequency of voltage on the transmission line 2 side at that time. Accordingly, the output signal, the voltage phase signal theta*IS, of the counter 116 is not equalized to frequency on the transmission line 2 side, but it is brought to a voltage phase signal having the fixed frequency of a value close to the frequency.
