Title: Preparation of optical fiber preform
Inventor: SUZUKI RYOJI
IPC: C03B37/014
Filed: 1989-07-22
Abstract: PURPOSE:To improve the control accuracy of the deposition amount of an optical fiber preform by measuring the whole weight of a glass fine particle deposition product during a deposition process, comparing the measured value with a pre-set value, changing the conditions of the deposition in response to a difference between measured value and the pre-set value when the difference is less than the increase of one layer, and subsequently performing the final traverse. CONSTITUTION:A combustion gas H2, a combustion-improving gas O2, a raw material gas SiCl4 and Ar gas are fed into a burner 3 for synthesizing glass fine particles to produce the glass fine particles, and the burner is simultaneously traversed to form one glass fine particle deposition layer 2 on the periphery of a target material 1 per one traverse. The traverse is reciprocated several times to form several glass deposition layers 2. The weight of the deposition product is measured with a load cell 5 for each deposition of the glass deposition layer 2. A burner 3 is traversed under a definite combustion condition and a difference Wd between the weight increase DELTAW of one layer and a pre-set weight is measured. In the case of DELTAW<Wd the burner is further traversed under the same condition and in the case of DELTAW>=Wd the deposition process is finished by the next traverse. The deposition condition of the final traverse for the final layer is changed to adjust the deposition weight of the final layer.

Filed: 1983-10-12
Abstract: PURPOSE:To prevent breakdown while to improve the pump efficiency by setting the amplitude of angular springboard for pressing first seal member against a vane lower than 0.6mm. thereby shortening the stroke of said member. CONSTITUTION:At the instance when each vane 201-203 passes through the inlet 36 of delivery chamber 36, high shocking force will function onto each first member 291, but since the amplitude of springboard 30 for pressing the first seal member 291 against the vanes 201, 203 is set lower than 0.6mm., the stroke of each first seal member 291 is short to reduce the shocking force to be applied onto each first seal member 291 thus to prevent breakdown. While when setting the amplitude of springboard 30 lower than 0.6mm., the gap to be produced between each vane 201-203 and second seal member 292 when feeding pressurized air is reduced resulting in improvement of pump efficiency.

Title: Information device
Inventor: YOSHIMOTO KYOSUKE
IPC: G11B20/10
Filed: 1985-08-27
Abstract: PURPOSE:To attain correction of the wrong positioning information due to the secular change of temperature, etc. by controlling the reference point of the output of a position shift detector so as to obtain the minimum reproduction error frequency of a specific information signal including an error check code. CONSTITUTION:A specific information signal including an error check code is recorded previously at a prescribed position of a disk 24 with large jitter. Thus the reproduction error frequency of information is increased just with a slight position shift detected between the reference point of a position shift detector 17 and an optimum point. An error detecting circuit 26 detects and corrects an error of the reproduced information and at the same time sends each time the information to a counter circuit 27 in the form of pulses. The circuit 27 counts the pulses and sends the count result to a microcomputer 28. The computer 28 changes the offset to be applied to the detector 17 and compares each offset value with the count result sent from the circuit 27 to obtain the offset value with which the count value is minimum. The obtained offset value is held hereafter. As a result, the reference point of the detector 17 can be automatically corrected.

IPC: H02P23/07
Filed: 1984-09-14
Abstract: PURPOSE:To completely suppress the vibration of an AC motor without the type and the load of the motor nor the operating conditions such as th speed range by detecting the input current of an inverter and controlling the frequency of the inverter through a power compensator. CONSTITUTION:A current transformer 13 detects the input current ID of an inverter. This detection signal is inputted through a DC current polarity discriminator 14, a stabilization discriminator 15, a power compensator 30, a limiter 18 and a gain converter 19 to an adder 20, and added to a frequency set signal fR. Thus, when a motor abnormally vibrates, a stabilization signal having the same polarity as the basic frequency command of the inverter from when a negative DC current starts flowing and rising at the time constant within approx. twice to three times of a carrier period is added to the basic frequency of the inverter, and a stabilization signal having entirely reverse sign and symmetrical to the above stabilization signal is added thereto from when a positive DC current starts, on the contrary, flowing to suppress the vibration.
