Title: Circuit for driving semiconductor laser
IPC: H01S5/042
Filed: 1992-03-17
Abstract: PURPOSE:To carry out a high frequency current overlapping ON/OFF operation at a high speed and to shorten a semiconductor laser in modulation rise/fall time in recording by a method wherein a high frequency current superposing circuit and a high frequency current superposing ON/OFF circuit are housed in the same shielded case. CONSTITUTION:A current control signal is fed to a semiconductor laser drive circuit 2 through the intermediary of a first filter 11, and record data are also inputted into the circuit 2 through the intermediary of a second filter 12, whereby a current made to flow through a semiconductor laser 1 is determined. A high frequency oscillation circuit 6 and an amplifier 7 are arranged inside a shielded case, so that no filter is interposed between the semiconductor laser drive circuit 2 and the semiconductor laser 1, and consequently the semiconductor laser 1 is shortened in modulation rise/fall time at recording. Furthermore, the ON/OFF operation of the high frequency oscillation circuit 6 and the amplifier 7 can be carried out at a high speed.

Title: Thin film solar battery and its manufacture
Inventor: MURAMATSU SHINICHI
IPC: H01L31/04
Filed: 1994-04-28
Abstract: PURPOSE:To take out even such a carrier that is generated in an amorphous phase by forming at least one of semiconductor thin films in a mixed phase of an amorphous phase and crystalline phase, with the crystal phase containing a columnar or conic phase nearly perpendicular to the main surface of a substrate. CONSTITUTION:After forming an n-type microcrystalline silicon film 3 on a metallic substrate 2, the crystallinity of the film 3 is improved by irradiating the filnt 3 with X rays and a semiconductor thin film 4 is formed on the filnt 3 by using the plasma CVD method. Then the thin film 4 is irradiated with X rays by using a mask for X rays having openings at 3-mum intervals in both the longitudinal and transversal directions. As a result, n-type crystal areas 43 having diameters of <=1mumphi are formed in the amorphous area 41 which is substantially formed in i-type of the thin film 4 at the positions corresponding to the pattern of the mask. Carriers generated in the amorphous phase 41 having a high carrier generating rate can be run by selectively guiding the carriers to the crystalline phase 43 having a good carrier running property by forming an electric field between the amorphous phase 41 and crystalline phase 43.

Title: Testing circuit for signal processor
Inventor: ISHIKAWA YUTAKA
IPC: G06F11/22
Filed: 1986-04-22
Abstract: PURPOSE:To curtail a circuit scale and to obtain a large effect for practical use, by inputting an instruction code and a data from an external terminal and executing an operation test of an LSI. CONSTITUTION:When selecting signals SS1, SS2 are '0', a signal from an input terminal IT1 is obtained in the output of a selector SL1 through a register RG1 by synchronizing with a clock CK. The output of the selector SL1 corresponds to a transfer instruction. On the other hand, an output of a selector SL2 goes to '0' since input terminals SA, SB are '0'. The output of the selector SL2 is made to correspond to an arithmetic operation instruction, and it is '0', therefore, since it is made to correspond to an operation for executing no arithmetic operation, data of input terminals IT2, IT3 can be transferred to a data processing part DT through registers RG2, RG3, bus driver BD and an internal data bus DB. When the selecting signal SS1 and SS2 are '0' and '1', respectively, the transfer instruction and the arithmetic operation instruction can be inputted from the input terminals IT1, IT2 to the selector SL1 and SL2, respectively.

Title: Palette fast-feed device
Inventor: OKAWA IKUO
IPC: B65G47/88
Filed: 1989-04-11
Abstract: PURPOSE:To give a positioning function and to shorten the stopping time by fixing a stopper roller to a drive shaft which reciprocatingly turns over a predetermined angle, through the intermediary of a lever, by coupling a motor-driven fast-feed roller incorporating a one-way clutch, to the drive shaft through the intermediary of a turntable lever, and by connecting both levers through the intermediary of a spring. CONSTITUTION:When a palette 2 having a stopper block 2a at the lower surface thereof is transferred on a transfer conveyer 1, the stopper block 2a abuts against a motor-driven roller 19 for fast-feeding the palette. Then, the palette 2 abuts against a stopper roller 14 for stopping the palette while it is pressed against a conveyer guide 1a by a spring 25 stretched between levers 13, 18, and is therefore stopped. A one-way clutch which is not shown and which is disposed between the drive roller 19 and a roller drive shaft 21 inhibits the palette 2 from bounding due to a shock at this instant. Then, the lever 13 is turned by a predetermined angle by the drive shaft 11 so as to disengage the stopper roller 14, and accordingly, the palette may run. Thus, it is possible to stop the palette at a precise position in a short time.

Abstract: PURPOSE:To reduce data storage capacity and allow even a low-speed computer to measure hardness with sufficient precision by storing image data on only a zone where the numbers of black picture elements before and after indenter depression increase in their difference above a specific value and performing image processing in hardness measurement. CONSTITUTION:An image of a test surface before indenter depression is picked up, and the number of picture elements which are judged as black dots in each zone (an, bm) is counted and stored. Then, an indenter is pressed and an image of the test surface after the indenter depression is picked up to count and store the black picture elements in each zone. Then, the numbers of black picture elements in each zone before and after the indenter depression are compared with each other, and zones A-D are stored selectively when the difference in the number of black picture element before and after the indenter depression increases above the specific value. Then, an image sensor 3 is driven again to pick up images of said zones A-D, and all picture element data in the zone are stored. Then, only the stored picture element data are used to perform image processing, and an indentation part formed by the indenter depression is extracted to measure its size, which is converted into hardness and printed on a printer 10.

Title: Method for operating blast furnace
Inventor: YAMAGUCHI KAZUYOSHI
IPC: C21B5/00
Filed: 1990-04-06
Abstract: PURPOSE:To evade lowering of substitution ratio and defective permeability, to improve productivity and to reduce fuel ratio even if a large quantity of fine powdered coal is blown, by blowing H2O source and CO2 source at the same time in the operational method for blowing the fine powdered coal from tuyere part. CONSTITUTION:In the operational method for blowing the fine powdered coal into the blast furnace from the tuyere part, the H2O source and/or the CO2 source are blown at the same time of blowing the fine powdered coal, or H2O source and/or CO2 source are blown in the blasting air. By this method, in the case the excess oxygen ratio is <=1.0, even if carbon and hydrogen in the fine powdered coal are burnt, the whole gas does not become CO2 and H2O, but the produced unburning char can be eliminated in the raceway. Therefore, as the unburning char is not discharged from the furnace top and not caught into furnace core, the lowering of substitution ratio and the defective permeability are not developed, and the productivity is improved and the fuel ratio is lowered and molten iron can be stably supplied.

Filed: 1994-04-28
Abstract: PURPOSE: To diagnose local and remote adapters without using dedicated hardware by assigning a local logic address to communication between local terminal equipment and local adapters. CONSTITUTION: When diagnosing a local TA, a DLCI, which is not scheduled for communication between DTE is used, and when diagnosing a remote TA, a DLCI assigned to communication with a remote DTE connected to the remote TA is used. When diagnosing a local TA 18 and a remote TA 20 and 22 by a DTE 12, the DLCI for sending a diagnostic frame to the TA 20 or 22 sets a DLCI 200 or 300 assigned to the communication with DTE 14 or 16. In for the communication with the local TA 18, such a DLCI which is not scheduled for the communication between the DTE, is assigned. It is not necessary to register this local DLCI on a network 10, thus no charged is made from the service provider of network 10, either.
