Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To secure required response characteristics by PWM control for dynamic control characteristics on transition and at the same time perform operation with a desired pulse pattern in steady state by controlling a DC voltage so that the DC voltage becomes a DC voltage command value. SOLUTION: A control means 71a of a means 7 for controlling the amount of electricity compares a command dr of the amount of electricity of an axis (d) with an amount of feedback df being obtained from a detection means 5 and a pre-processing means 6 and a control signal corresponding to a d-axis error is outputted, and a d-axis reactance voltage Xiq, a d-axis AC voltage Vsd, and the like are applied, thus outputting an AC voltage command Vdr to a pulse generation means 8. Similarly, a control means 71b outputs an AC voltage command Vqr. Then, based on the AC voltage commands Vdr and Vqr, a pulse generation means 8 generates a pulse that is given to the solid switching element of the AC/DC power converter units 31a and 31b, thus enabling dynamic control performance in transition to secure response characteristics required by PWM control and at the same time performing operation with a desired pulse pattern in steady state.

Thence, the presence composition as the inorganic component is mixed with an organic binder, plasticizer and solvent at a specified proportion into a slurry, which is then put to film formation into a dielectric green sheet. Thence, an electrically conductive paste prepared by kneading an organic vehicle with an inorganic component consisting mainly of CuO is put to screen printing on the green sheet to form an electrode pattern. The resulting green sheet is then laminated with other electrode-formed green sheet(s) made in a similar way followed by pressing into a multilayer form, which is then heat-treated to remove the binder contained, and the resulting multilayer form is further heat-treated in a mixed gas atmosphere of H2 and N2 to reduce the electrode material into Cu followed by roasting in a N2 atmosphere, thus obtaining the other objective laminated ceramic capacitor.

Title: Vacuum treatment apparatus
Inventor: KOSHIBA MITSUNOBU
IPC: H01L21/302
Filed: 1989-11-29
Abstract: PURPOSE:To separate an object to be treated within a short time by a method wherein a supply operation of a DC voltage of an inverse potential is stopped according to a detection result that a pressure of a gas has become a prescribed ratio with reference to a prescribed pressure. CONSTITUTION:An electrode 3 of an electrostatic chuck 1 is connected respectively to a DC power supply 4 of a positive potential and a DC power supply 5 of a negative potential via switches 6 and 7; a DC voltage of a prescribed potential is applied; an electrostatic attraction force is generated; an object 10 to be treated is attracted; in this state, a gas of a prescribed pressure is supplied into a gap. The gas is leaked into a vacuum chamber 34 as the attraction force is lowered; the pressure is lowered. Consequently, when the lowered pressure becomes a prescribed rate with reference to a prescribed pressure, the attraction force is lowered sharply. Accordingly, a supply operation of the DC voltage of an inverse potential is stopped. Thereby, the object 10 to be treated can be separated from the electrostatic chuck 1 within a minimum range of the attraction force without damaging the object to be treated; a time required to separate the object 10 to be treated can be shortened.

Title: Piezoelectric device
Inventor: OTA JUNJI
IPC: H04R17/00
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric device with enhanced reverberation characteristics, noise immunity and productivity. SOLUTION: A piezoelectric element 1 is contained in a case 7, and electrodes 3, 4 of the piezoelectric element 1 and a cable 5 are interconnected via a thin metallic terminal 6. Thus, no elastic wave is propagated to the terminal 6, and the vibration of the piezoelectric element is not reflected in a connected position of the thin metallic terminal so as to obtain an excellent reverberation characteristic with a short pulse waveform falling time. Furthermore, since it is not required to directly connect the cable to the electrode of the piezoelectric element, the productivity can be enhanced.

CONSTITUTION:A light emitting part 21 for emitting beam in definite quantity, a light detecting part 22 receiving said beam to perform output corresponding to the quantity of light and an operational control part 29 for calculating the length of a sample A on the basis of the output of the light detecting part 22 when the leading end of the sample A shields a part of beam and a preset output value are mounted. When the leading end of the sample A placed on a base stand shields a part of the beam, the output of the light detecting part 22 changes corresponding to the shield quantity. Therefore, on the basis of the output when a reference gauge having a known length shields a part of the beam and the output of the light detecting part 22 relating to the sample A, the change of the length of the sample A from the reference gauge can be calculated. The length of the sample A can be calculated on the basis of said length and the length of the reference gauge.
