Patent JP-H0451705-A (JP)
Title: Oscillator
Inventor: SATO MAKOTO
IPC: H03B1/00
Filed: 1990-06-20
Abstract: PURPOSE:To suppress generation of microphonic noise by inserting a cushion member and a conductor metal spring between a case of an oscillation circuit and a panel case. CONSTITUTION:A conductor metallic spring 4 is inserted between an oscillation circuit case 1 and a panel case 2 accommodating the oscillation circuit case 1 together with a cushion member 3. Thus, the cushion member 3 absorbs and attenuates the mechanical shock or vibration energy of the oscillation circuit case 1 and the oscillation circuit case 1 connects to ground being a same level as that of the panel case 2 via the conductive metallic spring 4. As a result, since the capacitance between the oscillation circuit case 1 and the panel case 2 being a cause to load fluctuation is eliminated, load fluctuation due to mechanical shock and vibration is not caused and microphonic noise due to the load fluctuation is not generated.

Title: High-temperature sealing material and manufacture thereof
Inventor: MORI KAZUTAKA
IPC: C04B35/04
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a high-temperature sealing material having strong sticking force and high sealing performance by setting the powder sizes of zirconia powder and alumina powder to specific values, and specifying the mixing ratio of them. SOLUTION: Zirconia powder uses the coarse powder of 8-wt.% yttria stabilized zirconia, and its thermal expansion coefficient is 10.9×10<-6>  deg.C. The coarse powder is crushed to obtain large grains with the grain size of 10-40μm and medium grains with the grain size of 1-10μm. When alumina is added to zirconia, its thermal expansion coefficient is reduced. Fine alumina powder with the grain size of 0.1-1.0μm is used, and it is mixed with large-grain and medium- grain yttria stabilized zirconia. The mixing ratio is set to zirconia powder : alumina powder = 90/10 to 70/30, and a seal material having the densest filling of powder is obtained at this mixing ratio.

Title: Decoder circuit
Inventor: WATANABE TAKESHI
IPC: G11C16/12
Filed: 1982-09-17
Abstract: PURPOSE:To reduce the number of IGFETs, by forming only one of a multi- input circuit having many IGFETs to several word line outputs. CONSTITUTION:Since a write signal PG is at a potential of the readout power supply VCC, a potential of readout power supply voltage VCC and a write power supply voltage VPP are set to the same potential as the readout power supply voltage VCC at readout, a depletion M8 is turned on at the readout at all times and the potential of a word line WL is a ground potential being the same potential as that of an output point 2. The time when the potential of the wordline WL is discharged from logical ''1'' to logical ''0'' depends on a conductance gm of IGFETs M6, M8 and a load capacitance C1. When the potential of the word line WL is decided to logical ''0'', the IGFETM9 is turned on and an IGFETM10 is turned off, the potential at an output point 3 goes to logical ''1'', an IGFETM11 is turned off and a current from the write power supply voltage VPP to the word line WL is interrupted. Since the output at an output point 1 is separated into two with the address input signal, 2-NAND circuit of address input signals A1, A2 is halved to the word line output number.

IPC: H01G4/06
Filed: 1991-07-03
Abstract: PURPOSE:To reduce cost by forming a thin film capacitor which can be used for small-sized high density circuit elements with a substrate which does not call for surface processing. CONSTITUTION:After a lower electrode 7 is formed on an aluminum ceramic substrate 6, a tantalum film 8 is formed by a sputtering process.
