Title: Piezoelectric ceramic composition
Inventor: SUZUKI KAZUNORI
IPC: C04B35/475
Filed: 1985-05-30
Abstract: PURPOSE:To eliminate the need for the compensation of a piezoelectric constant by a temperature by making a specific quantity of Ca and Ti to be contained into a sintered body having bismuth layer-shaped structure consisting of a molecular formula PbBi4Ti4O15 as CaTiO3 or SrTiO3. CONSTITUTION:A piezoelectric ceramic composition in which 10-55mol% Ca and Ti are made to be contained in a sintered body having bismuth layer-shaped structure composed of a molecular formula PbBi4Ti4O15 as their oxide, CaTiO3, or 1-15mol% Sr and Ti in the sintered body as their oxide SrTiO3 is adopted. Since an additive, which has negative permittivity-temperature characteristics and is changed into CaTiO3 or SrTiO3 by sintering, is solid-dissolved to the piezoelectric ceramic composition consisting of PbBi4Ti4O15 bismuth layer-shaped ferroelectrics having positive permittivity-temperature characteristics, the temperature change of permittivity mutually denies and is kept constant. Accordingly, the piezoelectric ceramic composition displays constant permittivity regardless of a temperature change, and displays an approximately fixed piezoelectric constant.

A paper feed correction quantity WLFhosei obtained by converting the result into the minimum paper feed unit and the remaining quantity WLFr (-1) to be used next time are obtained (step S5). Finally, a paper feed quantity WLF=WLFm+ WLFhosei is obtained.

In the afternoon when the number of indoor people increased and cooling is not enough as the outer air temperature is risen increasing cooling load, the revolution of the fan 10 of the fan coil unit 5 for the outer air processing is reduced step by step from high speed to low speed so that the temperature of the returned chilled water detected by a returned chilled water temperature detector T1 not to exceed, for example, 12 deg.C, the quantity of introducing air is decreased. Therefore, the chilled/ hot water supply is operated within the rated capacity.

Title: Manufacture of compound semiconductor device
Inventor: ISHIMURA HIROSHI
IPC: H01L21/205
Filed: 1980-08-28
Abstract: PURPOSE:To activate an ionic injection layer of a compound semiconductor containing As uniformly in excellent reproducibility by thermally treating the ionic injection layer in an atmosphere containing Ar and AsH3. CONSTITUTION:The ionic injection layer of the compound semiconductor containing As is activated through heat treatment without a protective film. The rate of activation and reproducibility depend upon the kinds of atmospheric gases at that time. A GaAs substrate 12 containing the ionic injection layer 11 is placed in a quarts boat 2 in a furnace, Ar containing AsH3 with 1 Torr in molar partial pressure is flowed, and the substrate is thermally treated. The temperature is selected by the kind of atoms injected and the amount of them injected. The partial pressure of AsH3 in the atomosphere is also increased in order to prevent the decomposition of GaAs during the heat treatment because the vapor pressure of As of GaAs rises together with the treatment temperature. According to this constitution, the ionic injection layer can be activated and thermally treated at the rate of activation higher than conventional methods, stably and uniformly and in excellent reproducibility.

IPC: C09J5/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for hermetically sealing the end part and joint of stator bar and applying liquid seal thereto. SOLUTION: Using a viewer 50 and an epoxy applicator 52, a low viscosity epoxy is applied from the inside of chamber 36 of a stator bar end joint 20 entirely over the joint of adjacent conductors of a stator bar 16 and the joint between the joint 20 and the outermost conductor of stator bar. In order to form a thick barrier wall seal between a liquid coolant in the chamber and a brazing material, a high viscosity epoxy is applied onto a low viscosity epoxy using the viewer and applicator and then the epoxy is cured. Consequently, the barrier wall seal isolates the brazing material from the liquid coolant to prevent possibility of leakage and since a hermetic sealant is arranged on the interface between liquid coolant and brazing material, existing leakage is blocked in the way.
