Title: Plasma cvd apparatus
Inventor: IZUMI HIROHIKO
IPC: H01L21/205
Filed: 1986-03-03
Abstract: PURPOSE:To form a film of high quality and uniform thickness with a high speed by a method wherein heated substrates are provided in a vacuum chamber facing each other and a flat plate electrode is provided in the middle of the two substrates so as to be parallel to the substrates and magnetic fields which have components making right angles with electric fields are created on both sides of the electrode. CONSTITUTION:Reactive gas is introduced 2 into a chamber 1 and exhausted 3 to obtain required flow, composition and pressure. A radio frequency voltage is applied to an electrode 7 to induce glow discharges between the electrode 7 and anodes 4 and 4b. Electrons in plasmas are captured by the components of magnetic fields making right angles with electric fields induced by devices 13. As a result, high density plasma regions are created on both sides of the electrodes 7 and decomposition of the reactive gas is accelerated and deposition is carried out on the substrates 8 placed on the electrodes 4a and 4b with a high speed. The distances between the substrates 8 and the high density plasma regions are adjusted by devices 14a and 14b to make the thicknesses of the formed films uniform. With this constitution, even if species of growth are created in vapor phase, their growth is suppressed be electron bombardment and they do not give nonuniformity to the film structure so that a film of high quality and uniform thickness can be formed with a high speed.

Title: Optically coupled element
Inventor: MITSUI MASAYUKI
IPC: H01L31/12
Filed: 1995-03-03
Abstract: PURPOSE: To obtain stable insulation characteristics and photoconduction efficiency, and further, to make the entire thickness thinner. CONSTITUTION: A photo-detecting element 25 whose photo-detecting face faces a light emitting element 15 mounted on a light emitting element mounting part 12a of a central lead 12 an the light emitting side, is supported by making each electrode assigned around the light emitting element to be directly adhered to photo-detecting element mounting parts 21c-23c on the tips of each lead 21-23 on the photo-detecting side. So, even when the thickness of the photo- detecting element 25 varies, the interval between the light emitting face of the light emitting element 15 and the photo-detecting face of the photo-detecting element 25 is not varied, rather constant. Further, since the photo-detecting element 25 and each lead 21-23 are electrically connected each other without using a bonding wire, the thickness of an optically coupled element becomes thinner.

Abstract: PROBLEM TO BE SOLVED: To realize a highly efficient reproduction sound pressure and to extend a high limit frequency in an electromagnetic induction type loudspeaker that provides sound by utilizing mutual induction. SOLUTION: A primary coil 1 is placed so as to be enclosed in an edge part of a secondary coil 2, an induction current generated in the secondary coil 2 is increased and a cross sectional area of the secondary coil 2 placed at a magnetic gap 7 is increased so as to reduce the electric resistance of this part.

Title: Method for introducing plasmid to acetobacter
Inventor: YANO KEIJI
IPC: C12R1/02
Filed: 1984-03-09
Abstract: PURPOSE:To transfer mob(+) plasmid from a donor cell to the cell of Acetobacter, in high transfer frequency, by the zygotic induction using tra(+) plasmid as the helper. CONSTITUTION:A tra(+) plasmid (e.g. pRK2013) existing in E.coli and having a tra gene controlling the zygotic induction between the cells, is used as a helper to transfer a mob(+) plasmid (e.g. pRK290, pLAFR1) to an acetobacter by the zygotic induction method. Concretely, tra(+) plasmid is introduced into an E.coli holding a mob(+) plasmid, or an E.coli strain having mob(+) plasmid is mixed with another strain having tra(+) plasmid. The E.coli is cultured, and an acetobacter strain is added as a receptor strain to the cuture liquid. The transfer frequency can be further improved by filtering the above liquid mixture with a membrane filter and collecting the bacterial cell on the filter.

Title: Drive force transmission
Inventor: SAKAI TOSHIBUMI
IPC: F16D25/063
Filed: 1988-02-26
Abstract: PURPOSE:To lower transmission torque between front end rear wheels to such level as no trouble occurs in ABS(anti-lock brake system) control during brake operation by providing a check valve for releasing pressure only from one to the other pressure chamber partitioned through a blade. CONSTITUTION:Torque flows from rear wheel side to front wheel side in reverse input characteristic when brake is applied, and a blade 42 rotates relatively to a rotary housing 21 in the direction of an arrow through relative rotation between front and rear wheel drive shafts 15, 16. Since the inner pressure in a pressure chamber 43 produced through viscous frictional function of high viscosity oil 44 leaks through a check valve 51 to low pressure side, the inner pressure of the pressure chamber 43 is lowered. Consequently, torque to be transmitted from the drive shaft 16 to the drive shaft 15 decreases to decrease transmission torque for differential rotation thus allowing slippage of a multi- board clutch 25 and preventing trouble in ABS control.

Title: Method for forming gap of magnetic head
Inventor: SUENAGA TATSUTOSHI
IPC: G11B5/23
Filed: 1987-02-27
Abstract: PURPOSE:To perform gap formation with high accuracy by eliminating angular moment being generated in an azimuth core and reducing gap length distribution, by performing groove working on both back planes of a core half body, and pressurizing only a generated projecting part. CONSTITUTION:In the core half bodies 1a and 1b consisting of an amorphous thin film 2, a glass layer 3, a winding groove 4, and a gap plane groove 5, etc., are processed at azimuth of 20 deg., back plane grooves 6a and 6b which pressurize only a substrate which films the amorphous thin film on the back planes of both core half bodies are provided. As a result, it follows that the projecting part being generated by the working of the back plane groove is pressurized, and the angular moment generated by the azimuth can be eliminated, and also, since only an amorphous films substrate is pressurized even when fine movement is generated in a bonding layer, influence on a gap length can be reduced. In other words, it is possible to eliminate the angular moment generated in the azimuth core, and also, pressurization in a direction orthogonal to a pressurizing jig can be obtained, and to perform the gap formation with a few amount of gap length distribution and high accuracy.

Abstract: PURPOSE:To acquire a semiconductor integrated circuit whose wiring freedom is high and a wiring region area is small and a design method thereof by realizing a semiconductor integrated circuit wherein desired circuit design change is possible by changing only one wiring layer and a design method thereof. CONSTITUTION:A wiring region is constituted of a wiring group of first and second wiring layers and a through-hole group for connecting them. The wiring group of the first wiring layers is constituted of a basic wiring which connects logical cells and preliminary wirings 70, 72 existing in preliminary regions 60, 62 without a basic wiring. An insulating layer is provided with preliminary through-holes 80 to 86, 88 to 92 corresponding to the preliminary wirings 70, 72. If actual wiring is constituted by using preliminary wiring by changing and adding a second wiring layer after design is finished, it is possible to correspond to change of wiring just by changing one layer mask. Since both a first wiring layer and a second wiring layer are used for a basic wiring, effective wiring is possible and the area of a wiring region can be reduced.
