Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To provide the driving method of a piezoelectric transformer whose power conversion efficiency is always set to be maximum and to provide a piezoelectric transformer power conversion device. SOLUTION: The driving frequency of a piezoelectric transformer is set between a resonance frequency fr and an anti-resonance frequency fa in a piezoelectric transformer 31, to the intermediate frequency (fr+fa)/2 of the resonance frequency fr and the anti-resonance frequency fa, if desirable. Thus, the power conversion efficiency of a power conversion device is set to be maximum. In a driving frequency control means 35, the driving frequency is made to follow a minimum phase frequency f3 with which the phase ϕ of admittance |Y| becomes minimum, and therefore the driving frequency can be set to the intermediate frequency (fr+fa) of the resonance frequency fr and the anti-resonance frequency fa.

Title: Format recording method for disk device
Inventor: TSUYOSHI TOSHIAKI
IPC: G11B5/09
Filed: 1995-01-31
Abstract: PURPOSE: To provide a format recording method which improves the quality of reproduced signals in an ID section and reliability of a magnetic disk device that uses a format form in which the ID section and the data section are deviated in the radial direction of the disk by the distance according to the amount of deviation between the center of the recording track and that of the reproducing track. CONSTITUTION: Before the format recording operation forming the ID section, an erase operation is conducted to form an erase region 12 in the area between the ID section and the neighboring ID section. Consequently, when there is a possibility of noise generation due to residual positional deviation between the ID sections of neighboring tracks, the noise can be removed. Hence, especially at the time of re-format recording, the quality of reproduced signals in the ID section is improved and thereby it becomes possible to enhance the reliability of the disk device.

CONSTITUTION:The metal tapped from an electric furnace 1 for a ferroalloy and molten slag 4 are gravity-separated in a ladle 2 and only the molten slag 4 is stored in a molten slag pan 3. On the other hand, special steel dust, sludge, etc. are mixed with cast iron powder and a chlorinating agent (CaCl2, etc.) and the mixture is briquetted 5 by a briquetting machine 8. The briquettes are dried and preheated by a heater 7 and are prepd. into a feeder 6. The briquettes 5 are dropped from the feeder 6 simultaneously with falling of the molten slag 4 into the pan 3 and both are thoroughly mixed to accelerate a chlorination reaction. The Ni and Fe in the briquettes 5 are thus made into an Fe-Ni alloy. The molten slag 9 which has thoroughly completed the treatment is cooled to solidify and is fed to a screening stage 10 where the slag is crushed and screened. The reduced metallic particles consisting essentially of Ni are recovered.

Title: Pressure detector
Inventor: TAKEDA YOSHIAKI
IPC: G01L9/10
Filed: 1986-01-27
Abstract: PURPOSE:To improve detecting accuracy, by providing a pressure adjusting function to the spring having a larger spring constant among two springs, which have different spring constants and are provided in a coil, thereby limiting the reactance change of the coil to the minimum degree. CONSTITUTION:A coil 10 is sealed and fixed in a base table 1 with a resin. A diaphragm 4 is held with a cap body 3 having a pressure introducing port 2 at the center. A core 8 is engaged with a pawl part 6 of a pressure receiving table 5, which is mounted on the non-pressure receiving side of the diaphragm 4 so that the part 6 is attached and detached freely. The core is slidden on the inner surface of the coil 10 against the repelling forces of springs 9 and 13. The spring constant of the spring 9 is smaller than that of 13. The spring 13 is located closer to an adjusting screw 16. The initial load of the spring 13 is set so that it is larger than the load when a step part 7 of the pressure receiving table 5 is contacted with a recess part 12a at the lower surface of a sliding body 12, i.e., the load at the maximum deflection of the spring 9. The adjusting screw 16 is adjusted only when the spring 13 is operated. When the spring 9 is operated, the screw cannot be adjusted. Thus the reactance change of the coil is less, and the highly accurate detection can be performed.

IPC: H03G3/34
Filed: 1987-01-23
Abstract: PURPOSE:To decrease the inversion phenomenon in switching a gate circuit by providing a filtering part extracting individually a pulse noise and a signal component from an audio signal and an automatic gain control section controlling individually the gain of the amplifying part detecting the pulse noise based on each output signal of the filtering part. CONSTITUTION:When a frequency in the input signal VS1 of a gate circuit 1 is fS1, the detection level of the pulse noise of the detection level of the pulse noise is VD1 and the pulse noise generated in the inversion phenomenon is controlled so as not to be switched. When the input level of the audio signal is increased from the level VS1 to VS2, the noise detection level is increased from the level VD1 to the level VD2 so as to remove the noise to a slightly large noise than the level VS1. Then increasing the frequency of the audio signal from fS1 to fS2, the detection level at the input level VS1 from the fS1 to fS2, the detection level at the input level is increased from VD1 to VD1' so as not to detect a small noise. Thus, the inversion phenomenon is blocked even to the change in the frequency and amplitude of the signal.
