Abstract: PURPOSE:To prevent a welding part from being broken in the following process by using a sheet-thickness controlling means in a hot rolling process and welding the rear end of a preceding coil to the front end of a succeeding coil by making the thicknesses of both ends equal to each other, in welding together the hot rolling coils having thicknesses different from each other. CONSTITUTION:In seam welding together the rear end of a preceding coil 1 and the front end of a succeeding coil 2 of hot rolling coils having the thicknesses different from each other; a length (l1) part of the rear end of coil 1 and a length (l2) part of the front end of coil 2 are subjected to sheet-thickness controlling rolling in a hot rolling line to have each the same thickness within a range of 3-5m by a finish stand having a hydraulic rolling-reduction device excellent in responsiveness in a rolling reduction system. Both of the preceding and succeeding ends of coils are welded together by holding them with the grips 3 of a welder. Because of the same thickness of the welding part 4, a welding joint free from steps and bead remains is obtained, and the welding part 4 is prevented from being broken in the following pickling and cold rolling processes.

Title: Horizontal die clamping and vertical casting type die casting method
Inventor: DANNOURA SADAYUKI
IPC: B29C45/53
Filed: 1985-06-11
Abstract: PURPOSE:To eliminate the damage of a plunger tip and to improve the yield of a product by lowering the plunger tip and and casting sleeve prior to die opening of a casting product cast through the lower contracted part. CONSTITUTION:A block 48 is lowered by removing the oil pressure in a cylinder 51 to detach the casting sleeve 52 from a stationary sleeve 39 and at the same time the pressure oil of an injection cylinder 45 is released to lower a plunger 47 when the molten metal in a cavity 34 solidifies to the product. The piston rod of a die clamping cylinder is then retreated to move a movable platen 28 in the direction parting from a stationary platen 25, by which the dies are opened. The plunger tip and sleeve are lowered prior to die opening in the above-mentioned manner and therefore the plunger tip does not make the operation for ejecting a biscuit. The damage of the plunger tip is thus prevented.

Title: Heteroepitaxial growth method
Inventor: TAMAMURA KOJI
IPC: C30B29/40
Filed: 1988-05-23
Abstract: PURPOSE:To prevent the propagation of through dislocation of an underlayer on a regrowth interface surface and decrease a crystal defective density by growing a single crystal semiconductor layer further on a regrowth interface surface after the regrowth interface surface is formed on the surface of the single crystal semiconductor layer. CONSTITUTION:A single crystal semiconductor layer 5 of a kind different from silicon is formed on a silicone substrate 1. After a regrowth interface surface 6 is formed on the surface of a semiconductor layer 5, an AlyGa1-yAs layer 7 is formed by MOCVD or MBE, after which a single crystal GaAs layer 8 used as an active layer is grown to a required thickness. An Si substrate 1 is once removed out of a growth device and an AlxGa1-xAs layer 5 is exposed to air in this way, a regrowth interface surface 6 being formed, and a layer 7 is formed thereon. Therefore, at the time of the formation of this layer 7, the through dislocation of the underlayer of the regrowth interface surface 6 is bent chiefly in a lateral direction, and the propagation toward an upper direction is prevented. As a result, the crystal defective density of dislocation in the semiconductor layers 7 and 8 formed on the interface surface 6 becomes low.

Title: Inverter
Inventor: ISHII HIDEHIRO
IPC: H02P27/06
Filed: 1994-06-07
Abstract: PURPOSE:To obtain an inverter which can be operated with highest efficiency by controlling the AC output voltage such that the input voltage is minimized. CONSTITUTION:A current sensor 3 detects the input current to a rectifier 1 from an AC power supply 10. A zero-cross detector 4 detects the zero-cross of input voltage from the AC power supply 10. Based on a zero-cross signal from the zero-cross detector 4, a sine wave generating section 22 generates a sine wave having a period identical to that of AC voltage from the AC power supply 10. Based on an input current signal from the current sensor 3 and a sinusoidal signal from the sine wave generating section 22, a power operating section 23 operates a value approximately proportional to the power being fed from the AC power supply 10 to the rectifier 1. A control section 24 then controls the AC output voltage from the inverter section 2 such that the value substantially proportional to the power operated at the power operating section 23 is minimized.

Patent JP-S5650603-A (JP)
Title: Amplitude modulating system
Inventor: OOOKA TAKAO
IPC: H03C1/00
Filed: 1979-09-29
Abstract: PURPOSE:To obtain the amplitude modulation wave having a reduced distortion in the amplitude modulating system in which a modulation is applied to the input carrier wave by the feedback modulation system, by reducing the limitation given to the maximum modulation frequency with the minimum value of the input carrier wave. CONSTITUTION:The input carrier signal is converted by the frequency-voltage converter 31 into the voltage which is proportional to the frequency of the carrier wave. This voltage is then compared with the reference voltage of the comparator 30 to produce the signal corresponding to the frequency range of the carrier wave. With this signal, a switching setting is given to the cut-off frequency of the HPF23 and the time constant of the wave detector 26 and the loop filter 29 respectively. As a result, a reduction can be prevented for the maximum modulation frequency due to the minimum value of the input carrier frequency of the device and against an optional input carrier. Thus an amplitude modulation wave can be obtained with a reduced distortion.

Title: Liquid crystal image display device, and manufacture of semiconductor device for image display device
Inventor: KAWASAKI KIYOHIRO
IPC: H01L21/336
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To improve the aperture ratio of an active type liquid crystal image display device. SOLUTION: Source and drain wires 3 and 19 are constituted by laminating a heat-resisting metal layer or silicide layer, an aluminum layer, and an insulating layer 20 and have the flanks insulated by anode oxidation, and a pixel electrode 18 is exposed. This constitution does not have the insulating layer 20 on the pixel electrode 18 to improve the aperture rate and no unnecessary step is present around the pixel electrode 18, so the outer peripheral part of the pixel electrode 18 need not be shielded from light by a black matrix, so that the aperture rate is further improved. The pixel electrode is formed on a gate insulating layer, so no nonorientation state is generated at the time of an orienting process.

Abstract: PURPOSE:To prevent skew and to improve the convenience in usage by forming 1st to 5th logic circuits identically and using an even number of logic circuits so as to make the delay time of the leading of an inverted signal to be delayed and the delay time of the trailing the same. CONSTITUTION:A signal coming to a terminal 30 is outputted from a terminal 45 via an even number of NAND circuits.

This is similar in other even number of NAND circuits. The delay time of the 2nd to 5th modes is an integral number of multiple of the delay time T1 in the 1st mode as 2.T1 to 5.T1 and a delay time proportional to a terminal giving a selection signal of an L level is obtained and the circuit offers excellent convenience in usage.

Title: Periodic function signal generating device
Inventor: MATSUSHIMA MASAO
IPC: G10H5/00
Filed: 1978-10-14
Abstract: PURPOSE:To obtain plural number of different periodic function signals simultaneously and in parallel by performing the reading of the periodic function data via the clock pulse featuring the frequency in accordance with the frequency of the periodic function signal. CONSTITUTION:The data of at least one cycle featuring the periodic function signal waveform which is required at processor CPU are formed with every signal in the form of digital signals Sd1-Sdn. These digital signals receive addition of the address designation signals to be sent to memory MM for memorization. Clock pulses CP sent from clock pulse generators CPG1-CPGn turn to reading CP to MM, and their frequencies are prescribed by velocity signals Ss1-Ssn. Thus the periodic function data are read out as the frequencies corresponding to the velocity signals. In this way, the data showing the periodic function signals stored in MM are read out by the frequencies required. And by repeating this reading in a high speed, various types of periodic function signals can be generated at one time.
