Patent JP-S6027828-A (JP)
Title: Mos-fet strain gage
Inventor: KARASAWA SHINJI
IPC: G01L1/22
Filed: 1983-07-26
Abstract: PURPOSE:To obtain a super-miniature strain gage, whose performance is stable, by utilizing the change in characteristics of an MOSFET caused when stress is applied to the gate or the gate oxide film of the MOSFET. CONSTITUTION:The characteristics of an MOSFET are changed when stress is applied to the gate or the gate oxide film of the MOSFET. The applied stress is detected by said change. Namely, by using the pressure sensitive characteristic of an MOS load resistor yielded by the diode connection between the gate G and the drain D of the MOSFET, a strain gage is formed by combining said device and a pressure receiving diaphragm. Thus the super-miniature strain gage, whose performance is stable can be obtained.

Title: Method for adding ti to molten steel
Inventor: ASAYAMA YUKIAKI
IPC: C22C33/04
Filed: 1982-08-03
Abstract: PURPOSE:To add Ti to molten steel in a high yield by adding a small amount of ferrotitanium to the molten steel heated to a high temp., solubilizing alumina, and adding the required amount of ferrotitanium. CONSTITUTION:In order to add readily oxidizable Ti to molten steel in a high yield, after heating the molten steel to 1,580 deg.C, Fe-Ti consisting of about 40% Ti and about 60% Fe is added so that Ti is contained by 0.2-0.3%. The molten steel is agitated with an alumina rod preheaed to high temperature to solubilize alumina in the molten steel, thereby deoxidizing the molten steel. After killing the molten steel for several min. Fe-Ti is charged by an amount corresponding to the desired composition, and the molten steel is agitated again with an alumina rod. Readily oxidizable Ti can be added to the molten steel in the air on an inert gaseous atmosphere in a high yield.

Title: Semiconductor device and manufacture thereof
Inventor: KOBAYASHI KEIJI
IPC: H01L21/316
Filed: 1990-05-28
Abstract: PURPOSE:To enable formation of a homogeneous interlayer insulation film or buried insulation film and flattening of a multilayer interconnection without impairing the characteristics of an element by a method wherein BPSG (boric- phosphoric acid silica glass) containing at least one kind of ion out of As, Sb and Bi is used as a glass film which is deposited on a semiconductor substrate by a CVD method. CONSTITUTION:By doping at least one kind out of As, Sb and Bi at the position of a glass mesh forming ion or a mesh modifying ion of a BPSG film 3, a reflow temperature is made low. As for the composition of the BPSG film 3, a glass structure is made to be a release structure by making the composition be BO3/BO4<=4. Thereby the viscosity is lowered, reflow is facilitated and the corrosion resistance of a wiring material is improved. When the composition is set in the range of B2O3/P2O5>=1, corrosion of the wiring material is reduced remarkably and the temperature of the reflow is turned to be low. By forming a ZnO glass film by a CVD method using a gas containing an organic compound of zinc and a glass mesh forming ion, besides, the glass film flattened at a lower reflow temperature is obtained.

IPC: G03G21/06
Filed: 1984-06-30
Abstract: PURPOSE:To prevent a useless toner from adhering onto a photosensitive body by providing a conductive toner stirring brush for rubbing the surface of the photosensitive body, between an electrifying device and a developing and cleaning device, and removing an unnecessary electrified area from on the photosensitive body. CONSTITUTION:In a two rotation and one copying system, the same voltage of the polarity as electrification of a photosensitive body 22 is applied to a toner stirring fur brush 24 provided between an electrifying device 23 and a developing and cleaning device 25, therefore, a residual toner after the transfer is stirred up uniformly on the photosensitive body 22. When an electrified area required for forming a latent image passes through the brush 24, the brush 24 is grounded and the potential of an unnecessary electrified area becomes extremely low, and the residual toner on the photosensitive body 22 and charge are erased completely by the cleaning device 25. Accordingly, an image of high quality is formed, the electrification and transfer are executed by one high voltage generating unit, and a device of small size and low cost can be obtained.

Title: Control method of idling speed of internal combustion engine
Inventor: NAKANO JIROU
IPC: F02D41/22
Filed: 1982-08-03
Abstract: PURPOSE:To provide a fail safe treatment to prevent the abnormal rise of an engine speed by detecting the non-operation state of a control valve from the lack of surge voltage to be generated when an idling speed control valve is driven intermittently. CONSTITUTION:When an idling speed control valve 26 is operated as between times T0-T1, an output V5 of a decision circuit 78 to be inputted to CPU60 is inversed at a period corresponding to the driving interval of the idling speed control valve 26. Now, at time t1, suppose a connector of a drive circuit 72 comes off, a drive transistor 86 cannot drive the idling speed control valve 26, and therefore, the surge voltage of possitive polarity cannot be generated. Consequently, the output signal of the decision circuit 78 cleared by CPU60 is kept at the low level and when CPU60 reads the output level from an input port to detect the low level at the time t2, fuel cut is executed as a fail safe treatment.

Abstract: PURPOSE:To obtain a heat-treated plate for powder metallurgy which is strong to abrasion, has good melt stickability to sintered metals and is inexpensive by coating the surfaces of carbon or graphite with composite oxide of ZrO2 and metallic oxide having spinel structure by melt spraying. CONSTITUTION:After a carbon or graphite plate is dried at about 250-350 deg.C, powders of ZrO2 and metallic oxide having spinel structure such as MgAl2O4 are mixed and the powder mixture is melt-sprayed and coated on the surface of said plate by a flame melt spraying method using gaseous oxygen-acetylene or a melt spraying method using plasma, and the melt-sprayed film is subjected to a stabilizing treatment if necessary, whereby the heat-treated plate is obtained. If the film thickness of the coating layer is <=10mu, there is no effect of the coating material and if >=1,000mu, the joining strength in insufficient. The most suitable amts. of ZrO2 and the oxide of spinel structure is 1/5-5/1 by weight. If <=20wt% Y2O3 or CaO is added to the above-mentioned composite oxide, the coating layer having much stabler strength is obtained.

Abstract: PROBLEM TO BE SOLVED: To increase the cutting speed by reciprocating a work in parallel with a wire. SOLUTION: A work reciprocating mechanism 21 for reciprocating a work W is fitted to a work elevating mechanism 5. This work reciprocating mechanism 21 is provided with a motor 22 as the power for reciprocating the work W, and a motor pulley 23 is fitted to a motor shaft of the motor 22.
