Title: Semiconductor manufacturing device
Inventor: NISHIMURA YOICHI
IPC: B05C11/08
Filed: 1990-11-08
Abstract: PURPOSE:To enable the dispersion in a coated film thickness between and in wafers to be fed-back immediately by a method wherein the film thickness immediately after the coating step is optically detected to be compared with the set up film thickness so that the processing revolution of wafer and the temperature of photoresist may be adjusted by the command of a controller. CONSTITUTION:A wafer 11 sucked down onto a chuck 10 is coated with a photoresist from a nozzle 9 while being driven by a motor 8 and then carried to a film thickness measuring part. Next, the film thickness measuring part equipped with a mechanism measuring the film thickness by the light passing through a lens 12 classifies said light per wavelength using a spectroscope 13 to quantify the light by a CCD 14. Next, the signals of the quantification are transmitted to a CPU 11 to be compared with the film thickness previously set up in a CRT and then control-signals are further transmitted to a resist thermostat 7 fitted with the motor 8 and a heater so that the wafer revolution and the photoresist viscosity may be adjusted to control the film thickness.

Title: Preparation of denture and resin denture with resin base
Inventor: TAKASHIMA MASAYUKI
IPC: A61C13/007
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent a slippage of or dropping from a core of an artificial tooth on preparation of a denture by forming a projection for temporalily binding to a core portion at a part to be buried with a core material on an artificial tooth used on the preparation of a denture with its resin base. SOLUTION: A projection 2 is formed by dropping a resin from a packing apparatus at a portion to be buired with a core material of an ready made artificial tooth 1. The position where the projection is formed corresponds to a position to be exposed from a wax base 3 on preparation of a wax denture, namely a position corresponding to a core 4 to be buried with the core material afterwards. Thus, by forming the projection 2 at a buried portion of an artificial tooth 1, the projection 2 functions as a rack for the core 4 and so as to be able to bind the artificial tooth to the core 4 after cured. Thereby the artificial tooth 1 is allowed to keep an appropriate position based on occulusal adjustment on preparation of the wax denture till the core 4 is removed in the final step of the prepartion of denture.

Title: Optical bistable semiconductor laser
Inventor: KUNO MASAAKI
IPC: G02F3/00
Filed: 1986-12-19
Abstract: PURPOSE:To increase the isolating resistance between electrodes and to obtain optical stability readly, by forming a laser layer structure including a one-conductivity type clad layer, an active layer and an reverse-conductivity type clad layer on a substrate in a mesa stripe, and embedding a semi-insulating semiconductor layer on both sides of the mesa stripe. CONSTITUTION:As a laser layer structure, an n-InP clad layer 2, a non-doped InGaAsP active layer 3, a p-InP clad layer 4 and p<+>-InGaAsP cap layer 5 are sequentially grown in an n-InP substrate 1. Then the laser layer structure is etched in a mesa stripe. As an embedded layer, a semi-insulating InP (Si-InP) layer 11 is grown on both sides of the mesa by an MOCVD method. Thus, the surface of the substrate is flattened. Then as insulating layers, a p-type electrode (Au/Zn/Au) 9A is formed in a gain region so as to cover the opening part of an SiO2 layer 8, and a p-type electrode 9B is formed in an absorption saturation region by the same way. An n-type electrode (Au/Au) 10 is formed on the rear surface of the substrate. The resistivity of Si-InP in the embedded layer is 10<7>-10<8>OMEGAcm. The high resistance layer is embedded in this way. A part of the isolating width Z (interval between electrodes) is removed from the gap layer 5. The isolation width is 15 mum and the isolation resistance becomes 5 kOMEGA. Thus excellent bistability is obtained.

Electrolysis is then effected by using preferably a 3-electrode system, platinum as a counter electrode and an aq. soln. of lithium chloride, etc., as an electrolyte and applying <=1V absolute value as an applied voltage. The period ions having the long chain aliphat. group are released into the soln. simultaneously when the org. metal complex attains 0 valency. The molecular film consisting of functional molecules is thus obtd. on the electrode base plate. This film is useful for information recording medium, etc.

Filed: 1991-10-24
Abstract: PURPOSE:To prevent the variance of a cell current, namely, the amplitude of a bit line regardless of the variance of the transistor width due to the variance of a process parameter in the memory cell of MOS transistors. CONSTITUTION:A memory cell M is selected by word lines WL1 and WLi+1 and is connected to bit lines B and the inverse of B. Word lines are driven by word drivers Xi and Xi+1, and word drivers receive the current supply from a cell current correcting circuit 100. When the transistor width is reduced to reduce the cell current, the cell current correcting circuit 100 raises the high level of word lines, and the source and gate voltages of transfer pates MT1 and MT2 of the memory cell M are increased to correct the cell current, to a standard value. Thus, the delay of the access tame accompanied with the reduction of the bit line amplitude is prevented.

Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a nozzle for use in discharging slag generated during a piercing operation which can be applied to any one of a gas cutting flame port, a plasma cutting flame port or a laser cutting flame port. SOLUTION: A nozzle A is comprised of a main body member 5 and a nozzle member 6. A center of the main body member 5 is formed with a fitting hole 1 to which a flame port B is fitted. The nozzle member 6 is formed with a plurality of injection holes 2. The injection holes 2 are used for injecting either oxidization gas or inert gas toward material to be cut during a piercing operation. One of the injection holes 2 is formed for every plurality of linear lines passing through an axis line 3 of the flame port B fitted to the fitting hole 1. Accordingly, gas injected from the injection holes 2 does not interfere with gas injected from another injection hold and the slag generated at the time of piercing operation is adhered in a radial direction. Due to this fact, it is possible to start a cutting operation in an easy manner from the end section where no slag is adhered at the hole.
