Abstract: PURPOSE:To eliminate the emboss of a picture and to attain the long life of an EL lamp by directly providing an EL (electro luminescence) light emitting layer at the rear surface of a liquid crystal panel and coating the EL lamp with the material of a high moisture resistance. CONSTITUTION:An EL lamp 12 is directly provided at the rear surface of a transmission type liquid crystal panel 11 and at the circumference, a rear surface sealing glass 10 is formed in place of a protecting film.

Title: Semiconductor integrated circuit device
Inventor: TACHIKI TAKUO
IPC: G06F21/60
Filed: 1983-01-31
Abstract: PURPOSE:To obtain a semiconductor integrated circuit device which can inhibit the double writing of an RM which can be rewritten by providing a writing limiting circuit which recceives the output signal of a memory element and inhibits the writing to the rewritable RM as well as said memory element. CONSTITUTION:An FAMOS transistor (TR)Q11 which is similar to a memory cell is provided to inhibit the double writing. The signal to be supplied to the gate of the TRQ11 is automatically produced by detecting a control signal given from outside or its final writing address signal when the writing of information is through with a memory array MARY. The threshold voltage of the TRQ11 is set at a high level. The generation of a writing control signal C1 is inhibited although the writing is carried out mistakenly to an EPROM with which the writing is through. This is due to the fact that the TRQ11 is turned off with its drain output set at a high level and therefore a signal C3 passed through an inverter IV is set at a low level. The TRQ11 is on with the first writing, and its drain output is set at a low level. Therefore the signal C3 is set at a high level, and a control circuit CONT receives the signal C3 and performs writing.

Title: Co2 gas shielded pulsed arc welding method
Inventor: SATO MASAHARU
IPC: H02M9/00
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To enable welding with reduced generation of spatters by increasingly and decreasingly controlling both pulsed current period and pulse frequency, keeping an arc length nearly constant and thereby stably carrying out the transfer of one pulse one droplet without deviation from the area of droplet transfer. SOLUTION: With comparison made between the reference value and the detected value of an average welding current, and on the basis of its difference in the current, the reference value of the pulsed current period is corrected, and a pulsed current period for a change in the wire extension from the reference length is determined. In addition, a pulsed voltage set value is determined for a change of the wire extension from the reference length by correcting a pulsed voltage reference value. When the wire extends and the length changes from the reference length, a pulsed current that brings the correctively set pulsed voltage is supplied for the correctively set pulsed current period.  Then, a base current period is determined so that the preset pulsed current value may coincide with the detected pulsed current value, thereby increasingly and decreasingly controlling the pulse frequency and maintaining a constant arc length.

Title: Holding system of fault information
Inventor: IGI YOUZOU
IPC: G06F11/34
Filed: 1982-01-29
Abstract: PURPOSE:To realize a means to hold assuredly the fault information although the power supply of a faulty device is cut off, by providing a means which receives the fault information given from the faulty device and then holds a fault display signal by means of a power supply which is independent of the faulty device. CONSTITUTION:The output of a delaying circuit 51 is fed to a terminal CL of a flip-flop 71 via a gate 16 in a conductive state. Therefore the flip-flop 71 via a gate 16 in a conductive state. Therefore the flip-flop 71 is set on the basis of the fault information (a) which is fed to a terminal D and then delivers the held fault information (b) through a terminal Q. The information (b) energizes a held fault information display 91 via a driver 81 and is also fed to a terminal S of a flip-flop 120 via a gate 10 and a delaying circuit 110 which has about 200mm. delay time. Thus the flip-flop 120 is set. As a result, gates 6l-6n are blocked by the output supplied from the terminal Q of the flip-flop 120 and after a delay time. Then the setting due to the fault information produced thereafter is prevented for flip-flops 7l-7n.

IPC: H01L29/06
Filed: 1995-01-31
Abstract: PURPOSE: To realize multilayered structure by alternately laminating two kinds of many layers composed of different atomic species or compositions on a semiconductor substrate, implanting element ions except constituent ions of the multilayered structure, making the ions react with only one side layers, and changing the property of the one side layers. CONSTITUTION: Silicon epitaxial thin layers 32, germanium epitaxial thin layers 33 and a silicon cap layer 34 are formed on a semiconductor substrate 31 by a molecular beam epitaxial method. Thereon a silicon dioxide layer 35 is formed by a normal pressure chemical vapor deposition method, and oxygen ions are implanted. Just after the implantation, the oxygen smoothly distributes in a region 36. By heat-treating a wafer at 600 deg.C for 30 minutes, stable silicon dioxide is obtained in the silicon layers. In the germanium layers, oxide is once formed and reduced again to simple substance germanium. Oxygen is absorbed in silicon layers on both sides, and thin germanium layers 38 are left. Thereby multilayer structure to crystal semiconductor layers is easily formed.

The temperature controller 25 is set so that the surface temperature of the baked block is to reach a set point of about 1,000 deg.C in the neighborhood of the outlet of a primary chamber 9. After the deviated portion of a signal is processed by a constant and others in arithmetic and logic units 26a and 26b, a result is input both into a pressure controller 17 and a flow rate controller 21 as set signals, and a cascade control loop is constituted. In order to detect the surface temperature, a sensor not in direct contact to the block such as a continuous radiating thermometer is recommendable. The accuracy in control is improved and a purpose to cool baked block can be truly achieved by constituting a cascade control loop by the surface temperature of the block.

Title: Support mechanism for magnetic head slider
Inventor: HOSAKA SHUROKU
IPC: G11B21/20
Filed: 1989-01-23
Abstract: PURPOSE:To prevent the recording/reproducing errors caused by the resonance with use of a simple structure by preparing a pivot type interlocking part where a head slider interlocks oscillatably a slider support arm and at the same time adding a nonmetallic elastic material to the periphery of the interlocking part. CONSTITUTION:An interlocking part 24 of a pivot 22 is prepared so that the head sliders 7a and 7b interlock oscillatably the slider support arms 21a and 21b respectively. At the same time, a nonmetallic elastic material 25 like silicone rubber, etc., is added to the periphery of the part 24. Therefore the member 25 is easily deformed within its elastic range around the part 24 against the fluctuation of a recording medium 5. Thus the sliders 7a and 7b follow the fluctuation of the medium 5. Then it is possible to prevent the recording/ reproducing errors due to the resonance with use of a simple structure.

Abstract: PURPOSE:To simplify valves for an intake system by turning a rotary valve in the intake passage of a Miller cycle engine within a cylindrical valve turnable and axially movable, and controlling the opening and closing timing of the rotary valve through the turning of the cylindrical valve depending upon an engine operation condition, and an intake volume through the shift of the cylindrical valve in an axial direction. CONSTITUTION:In way of an intake passage, there is a rotary valve 33 provided, opening and closing synchronized with an engine, and the rotary valve 33 is made to turn within a cylindrical valve 32.
