Title: Semiconductor device
Inventor: HIKINO TETSUYA
IPC: H01L23/06
Filed: 1984-08-10
Abstract: PURPOSE:To obtain excellent high-frequency characteristics while preventing the creep-up, etc. of solder on a mounting to a substrate by forming a metallized section inside a vessel and connecting a sealing section to a grounding terminal through the metallized section. CONSTITUTION:The inside of the side wall 3 of a small-sized airtight vessel is metallized 4, and a semiconductor 7 is connected to a lead 5 as a grounding terminal through a bonding section 2, a mount section 21 for the semiconductor 7 and an external metallized section 10. The surface of the metallized section 4 on the inside of the side wall is coated partially 15 with a ceramic film, thus preventing a flow-down to a bonding section for a bonding wire 8 through the metallized section 4 of an adhesive material in the bonding section 2. The sealing section 2 is connected finally to the grounding terminal, thus generating no resonance at high frequency, then realizing a semiconductor device having stable characteristics.

Title: Semiconductor memory device
Inventor: KANAZAWA KATSUE
IPC: H01L27/11
Filed: 1983-09-12
Abstract: PURPOSE:To prevent useless current inflow into a memory by earthing a word line through a GaAs Schottky diode and clamping the potential of the word line and a column switch driving line at a prescribed value. CONSTITUTION:The word line WL driving normally-off type GaAs-MESFETs Q5, Q6 of a transfer gate connecting the nodes N1, N2 of a memory cell formed by an FF using a normally-off type GaAs-MESFET to bit lines BL1, BL2 is earthed through the GaAs Schottky diode SD1. Even if power supply voltage VDD is increased up to 2V e.g., the word line WL is clamped at 0.8V and current inflow from the gates of the FETs Q5, Q6 to the memory cell is prevented. Similarly, the potential of a column switch driving line CL is also clamped at 0.8V, so that current inflow from the gates of normally-off type GaAs-MESFETs Q7, Q8 to the memory cell through the lines BL1, BL2 is prevented.

Title: Optical modulator
Inventor: TOMITA AKIHISA
IPC: H01S3/10
Filed: 1988-07-05
Abstract: PURPOSE:To operate the optical modulator and to obtain a sufficient on/off ratio by providing a multiple quantum well structure where a quantum well for positive holes which is coupled in terms of quantum mechanics across a barrier layer is at the same spatial position with one of electron wells for electrons as a waveguide layer. CONSTITUTION:An n-clad layer 12 formed of InP to 1mum thickness by doping Si and the waveguide layer 13 of the multiple quantum well structure are laminated on an n type InP substrate 11. When no electric field is applied, an electron and a positive hole are localized in the quantum wells at the same position. Consequently, the wave motion functions of the electron and positive hole have a large overlap and the transmissivity of light by the absorption of an active layer is small, so that an off state is obtained. Namely, an on state and the off state are switched according to the localization of electrons between two quantum wells which are coupled in terms of quantum mechanics. The localization of the electrons is sensitive to the difference in potential between the two quantum wells. Consequently, the switching is performed with a small electric field and the optical modulator which operates at the low voltage is realized.

Title: Color filter module for projective light
Inventor: RICHARDSON BRIAN EDWARD
IPC: F21V9/40
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a lighting module for projecting light having various colors, hues and intensities. SOLUTION: This device includes a light source 10 and a reflector 12 for directing light along an optical path. A primary optical element 16 reduces the cross sectional area of an optical zone where light enters the area of a filter assembly 18 in the optical path. In order to generate light of color, hue and intensity desired by a user, filters are arranged in the filter assembly 18 under the change of a combination or an extent. The filters 18 may physically be positioned in the optical path, due to the refracting action of the optical element 16, but in this case, the filters 18 change the light projected from a lighting module without any influence on the beam by the time when a filter 18 is rotated for aligning a filter segment with the optical element 16.

Title: Method for degassing from molten metal
Inventor: MIZUKAMI YOSHIMASA
IPC: C21C7/00
Filed: 1990-06-28
Abstract: PURPOSE:To efficiently remove gases from a molten metal by bringing one surface of a porous material which does not allow the passage of the molten metal but allows the passage of the gases into contact with the molten metal and fludizing a gas which does not contain the gaseous components to be removed on the surface of the porous material while exposing the other surface to a reduced pressure. CONSTITUTION:A pipe 3 consisting of the porous material sealed at one end is immersed into the molten steel 2 held in a container 1 and the other end of the pipe is connected to a vacuum pump 4 to reduce the pressure in the pipe. Hydrogen 5 generated on the outer side of the pipe in contact with the molten steel is sucked into the pipe in this way and is discharged by the vacuum pump 4. Refractories which are usually used for treating the molten steel and have 10 to 30% porosity suffice as the porous material. The degassing speed is further improved if the gas 7 which does not contain the gaseous components to be removed is fluidized on the surface of the porous material exposed to the reduced pressure. The volume of the gas to be fluidized is sufficient at about 1 to 2l/min per 1 ton of the molten steel.

When the terminal enclosing cap 19 is fitted to the electric pole 11 in a state of a cable 12 being connected to the terminal board 17, the cable 12 can be put in a cable enclosing pipe 20 without being interfered on account of the opened parts. And the terminal enclosing cap 19 is fixed with a stop board touching the upper surface of the electric pole 11. A bolt 23 is inserted into the uniting holes 18A and 18B, and it is united with the electric pole 11 in a state of holding the cable inside. Accordingly, it is possible to prevent people other than workers from touching the terminal part 13 from the ground, breaking it, and stealing a electricity easily.

Title: Fuel injection timing control method at starting of diesel engine

IPC: F02D41/14
Filed: 1985-07-31
Abstract: PURPOSE:To make fuel injection timing controllable to an optimum, almost constant value irrespective of variations in each control element or the like, and especially improve a low temperature starting characteristic, by reflecting a learned feedback control value to an open-loop control value for use at the time of starting. CONSTITUTION:At the time of engine driving, when an engine is so judged that it is under the ignition feedback control by an output of an ignition timing sensor 38, under the idle stabilizing state, and also under the warming-up finish state at an electronic control unit 56, whether a learning value D0 in duty control of a timer control valve 48 is larger than a duty control value D at the time of the esisting feedback control or not is judged. And, when a judgment is YES, the learning value D0 is set to the setting value, for example, such one reduced as much as by 0.1, down to a new learning value, but when NO is the case, the setting value, for example, such one adding 0.1 to the learning value D0 is set down to a new learning value. And, the duty control value is found out of this learning value, and the said control valve 48 is open-loop- controlled at the time of next starting.
