Filed: 1993-11-18
Abstract: PURPOSE:To prevent the intervention of foreign matter into the respective joint surfaces of a first sapphire wafer(SW) and second SW by subjecting these joint surfaces to stages for mirror polishing, etc., then tightly joining the joint surfaces in a prescribed vacuum furnace. CONSTITUTION:(a) The joint surfaces of 1 which is the first SW and 2 which is the second SW are mirror polished until the surface roughness Ra=50Angstrom  or below is attained, (b) by which 2A of the second SW is obtd. Next, (c) a cavity 3 is formed on the surface of the first SW 1A to be joined to the second SW 2A. Both joint surfaces of the first SW 1A and the second SW 2A are wet-washed to get rid of the org. and other stains on both joint surfaces to clean the surfaces. Next, both joint surfaces of the first SW 1A and the second SW 2A are arranged in a vacuum furnace by maintaining a slight spacing therebetween and the residual intrusions on the joint surfaces are removed. Next, (d) the first and second SWs are tightly joined while the state of heating the inside of the vacuum furnace to a prescribed vacuum degree and joining temp. is maintained, by which the cavity-contg. wafer 4 is produced.

Title: Wait function test circuit for ice
Inventor: SUGIMORI MASAYASU
IPC: G06F11/22
Filed: 1989-11-30
Abstract: PURPOSE:To freely change the wait time and to improve the working efficiency by using a higher rank bit of an address bus outputted from an in-circuit emulator ICE as the set value of the wait number and changing the address to receive an access when a memory receives an access from the ICE. CONSTITUTION:When an ICE 1 has an access to a memory 4, the address information on the memory 4 is put on an address bus. The memory 4 gives an access to the data on the address corresponding to a lower rank address signal connected to an address input terminal out of the address information on the memory 4. At the same time, the memory 4 sends data to a data bus 14 in accordance with a control signal 11 and writes the data taken out of the bus 14 into a data area. On the other hand, a wait inserting part 5 outputs a data acknowledge signal 15 after a time equivalent to the weight number decided by the higher rank address information since a higher rank address signal 13 of the address bus is connected to a wait number setting terminal of the part 5.

Title: Am stereo transmitter and receiver
Inventor: OGURO KAZUHIRO
IPC: H04H1/00
Filed: 1988-12-12
Abstract: PURPOSE:To ensure the compatibility by modulating the amplitude of a signal obtained by setting an RZ SSB modulated wave at a fixed amplitude via a sum signal and therefore receiving a monaural signal via a conventional AM receiver. CONSTITUTION:An amplitude limiter 105 limits substantially the amplitude of a modulated wave obtained by an RZ SSB modulation wave generating circuit 104. An amplitude modulator 106 serves as a 2nd modulation means which modulates the amplitude of the output of the limiter 105 as a carrier wave with a sum signal. An amplitude limiter 202 sets the amplitude of the output signal of an RF/IF conversion circuit 201 at a fixed level. A frequency detector 203, an integrator 204, and a linearizer 205 demodulate a difference signal out of the output of the limiter 202. An envelope curve detector 206 uses the output signal of the circuit 201 as an envelope curve detection wave and outputs a sum signal. A matrix circuit 208 produces the right and left signals from the demodulated sum and difference signals and outputs both produced signals to a right signal output terminal 209 and a left signal output terminal 201 respectively.

Title: Method and apparatus for removing slit type back pressure
Inventor: NOZAKI MIKINARI
IPC: B22D27/13
Filed: 1986-12-27
Abstract: PURPOSE:To surely remove the back pressure by supplying air in a slit connecting through with the last arrival part of molten metal in a cavity and making the slit into the negative pressure by ejector effect. CONSTITUTION:The air supplied from an air supplying hole 5 is flowed in the slit 3 from the air supplying gate A through an air supplying slit 4 and exhausted to the outer part from an opening hole. When the air is passed through the air supplying gate A, the ejector effect is developed and the upstream side slit 3 (the last arrival part 2 of molten metal in the cavity) becomes the negative pressure. By this negative pressure, the back pressure at the last arrival part 2 of molten metal in the cavity is removed. In accordance with this, the molten metal is flowed in the slit 3, where is the least flowing resistance, while inducing caused by the negative pressure.

Title: Insulated wire for printed wiring board
Inventor: MITSUOKA AKIO
IPC: H01B13/16
Filed: 1989-12-01
Abstract: PURPOSE:To prevent disconnection of a wire at the time of wiring by applying polyamide paint to the surface of a copper conductor with a oxygen content of 15ppm or less, a phosphorus content of 0-1ppm and wire drawing workability of 99% or more and baking the polyamide paint. CONSTITUTION:In the case of a break of an insulated wire, a gap first occurs at the interface between a polyamide film and an annealed wire, a break occurs along the grain boundary of copper from the interface of the annealed copper wire whose elongation is small, and while the break is occurring, a crack of the polyamide film occurs until this insulated wire is broken. Pull fraction elongation is increased therefor as much as possible, and the oxygen content in copper component is reduced to decrease the grain boundary of the annealed copper wire as much as possible, and also it is necessary to reduce a deoxidizer or a phosphoric component. It is therefore preferable to set an amount of oxygen contained in copper at 15ppm, and an optimum content of phosphorus is 1ppm or less. It is necessary to set the workability at the time of wire drawing at 99% or more to make the orientation of crystal uniformly long with reference to the direction of tensile rupture. It is thereby possible to improve the characteristic of pull elongation of the insulated wire and prevent disconnection of a wire at the time of wiring.

IPC: H01M10/05
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To reduce mechanical strain, increase strength, and improve uniformity by heat treatment after a massive substance consisting of a metal oxide is pulverized and graded. SOLUTION: A metal oxide includes a lithium employed for a positive electrode of a lithium secondary battery and a tin or tungsten employed for a compound oxide of a transient metal and a negative electrode and the like.
