Title: Controller for motor
Inventor: MATSUO KEISUKE
IPC: H02P29/00
Filed: 1993-01-28
Abstract: PURPOSE:To provide a controller for a motor in which a variation in a rotating speed at the normal time is suppressed and which does not impair motor starting characteristics in the controller for controlling it at a constant speed by a periodic feedback of an FG signal (a cycle signal having a frequency proportional to a rotation speed of the motor). CONSTITUTION:A period signal TFG in which a period of an FG signal (a cycle signal having a frequency proportional to a speed of a motor 100) is compared with a period command value Tr to become a period error signal DELTATFG. A deciding unit 20 decides a magnitude of the signal DELTATFG, and outputs '0' as a reset signal when it falls within a predetermined range or '1' when it is out of the range. A disturbance estimator l estimates a disturbance torque according to the signal TFG and a drive signal D when the reset signal is '0', outputs a disturbance estimation signal (d) converted to the drive signal, and initializes the signal (d) and a digital value M in a high-frequency band cut-off filter 14 to zero when the reset signal is '1'. A corrector 10 adds the signal (d) to a control signal (c) to output a drive signal D in which influence of the disturbance torque is cancelled, and does not substantially correct when the reset signal is '1'.

Title: Airtightness testing method for pipe joint section of underground buried pipeline
Inventor: KAGEYAMA HIDEKI
IPC: E03F3/06
Filed: 1993-01-28
Abstract: PURPOSE:To enable the inspection of the airtightness of a pipe joint section in a short time by a method wherein the pipe joint section is wrapped airtight with a housing one at a time to reduce or increase a pressure in the housing before the burying of a pipeline part joined and then, changes in the pressure with the passage of time is observed. CONSTITUTION:Each of pipeline joint parts 10 is wrapped airtight with a housing 2 having a pressure gauge 21 before the burying of a pipeline part B arranged based on a working process of one day. The housings 2 are linked to a vacuum pump 3 through a hose 31 and a multiconnector 30. Then, a vacuum pump 3 is driven to reduce the pressure in a space within the housing 2 to a specified negative pressure. Then, the pump 3 is stopped and a valve 22 is closed to observe the condition of the pressure in the housings 2 with a gauge 21. But a transient pressure change is caused in the housings 2 and prevents the judgment of the airtightness until this change ends. This allows the division of the airtight locations at each joint part 10 to reduce individual airtight capacity and the ending of the transient pressure change in a short time thereby enabling the shortening of inspection time.

Abstract: PURPOSE:To prevent heating and deterioration of a switching element even though the resonant frequency of a resonance circuit is varied, by detecting the resonant condition of the resonance circuit, and at the same time, regulating the OFF period of the switching element responding to the resonant frequency of the detected resonant condition. CONSTITUTION:A resonance circuit to which the power is fed by a DC power source 63, a switching element 69 to set the resonance circuit at a resonant condition, and a control device which detects the resonant condition of the resonance circuit and outputs a synchronous signal to the single stable multivibrator of an oscillation circuit 65 depending on the detection are provided.
