Title: Manufacture of grain-oriented silicon steel sheet having good magnetic characteristics
Inventor: NISHIIKE UJIHIRO
IPC: C25F1/06
Filed: 1988-11-08
Abstract: PURPOSE:To manufacture the title steel sheet by subjecting a grainoriented silicon steel sheet finished with finish annealing to pickling treatment in a short time and to mechanical grinding with elastic abrasives and thereafter to electrolytic treatment in a bath of water-soluble halogenide. CONSTITUTION:The surface of a grain-oriented silicon steel sheet finished with finish annealing preferably by the use of an MgO series separating agent is subjected to pickling treatment in a short time of 10 sec to 2 min. The pickling is preferably executed at about >=50 deg.C with about 10 to 30wt.% hydrochloric acid or sulfuric acid, by which reticular fracture is effectively formed on a surface oxide layer. After that, the surface of the steel sheet is mechanically ground by using elastic abrasives. As the above elastic abrasives, the ones formed with an elastic stock such as polyurethane as a matrix and having about A 30 to 70 Shore hardness are preferably suitable. Then, the steel sheet is subjected to electrolytic treatment in a bath of water-soluble halogenide. As the electrolytic soln., the one having about >=20g/l concn., room temp. to about 90 deg.C soln.temp., about 10 to hundreds A/dm<2> number of current density is preferably used. In this way, surface oxide is stably removed to improve the iron loss and magnetic flux density.

Title: Electric wire number collator
Inventor: ITO MITSUO
IPC: H04B3/46
Filed: 1985-12-12
Abstract: PURPOSE:To enable long-distance number collation by applying constant-current digital transmission to the signal processing system between a transmission part and a reception part. CONSTITUTION:A photocoupling element 13 is provided between a signal controller 1 and a constant current circuit 2, and photocoupling elements 14 and 14' and a latch circuit 16 are provided for a distributing and a terminal number detecting function. The search signal drives the LEd of the element 13, and constant-current signal flows through elements 14, 15. The diode of the element 14 emits light to send a detection signal to the circuit 16, which latches it with a fetch signal. The detection signal is read out in order and becomes an intermittent constant current signal, intermitting the light emission of a reception side diode. The transistor (TR) of the element 15 which is intermitted sends an electric signal to a signal decoder 10 and a display device 11 receiving the processed signal displays a number. A display device 17 for monitoring checks the state of the latch and displays it as a number.

IPC: E02D23/06
Filed: 1993-10-14
Abstract: PURPOSE:To convey a collection holder and an excavator safely and to prevent the inclination of an earth bucket by providing guides selectively corresponding to objects having different kinds of forms such as the collection holder, earth bucket, etc. CONSTITUTION:A collection holder 7 suspending an excavator and an earth bucket 12 are moved inside a storing container 5 of a pneumatic caisson. Earth from excavation is conveyed by the earth bucket 12, and after the completion of excavation, the excavator is suspended and is collected. In the case the collection holder 7 is moved, guide rollers 11 of the collection holder 7 are brought into contact with a collection holder fixed guide 13, a guide roller contact section 14c and a movable bucket guided collection holder fixed guide 15. In the case a relatively small earth bucket 1 is moved, the guide members are rotated along a virtual line. Positions of the guide members are adjusted in accordance with forms, so that the excavator and earth bucket 1 can be safely conveyed.

Title: Picture input device
Inventor: OMIYA MOTOHIKO
IPC: H04N1/19
Filed: 1990-10-19
Abstract: PURPOSE:To reduce the memory capacity and to improve the processing speed by outputting the valid part of a binary picture data by a succeeding scanning from each picture valid data gate section. CONSTITUTION:A binary picture data outputted from N photoelectric conversion sections 1, 4 is fed to relevant tentative storage section 3, 6 via relevant picture valid data gate sections 2, 5. Since an undesired part is present on the picture to obtain one consecutive scanning image, only the valid part in the binary picture data fed from the relevant photoelectric conversion section 4 is outputted. The tentative storage section corresponding to one end of a visual field in the tentative storage sections 3, 6 received the valid part of the binary picture data by one scanning from the picture valid data gate section, then the part is stored at a write speed synchronously with the transfer speed of the binary picture data and the valid part of the stored binary picture data in one-preceding scanning stored is read at a read speed being a multiple of N of the write speed. Thus, the memory capacity is less and the processing speed is quickened.

Title: Image processor
Inventor: NISHIZAKI SHINGO
IPC: G06T7/00
Filed: 1993-10-15
Abstract: PURPOSE:To execute the correction processing of a contour of a character and smoothing processing of a picture part with a simple hardware/software by collating extracted binary image information with plural binary matrix data stored in advance. CONSTITUTION:A collation section 7 sequentially collates received image information with valid data of matrix data from an area discrimination data table 6. When the collation result indicates coincidence, a changeover circuit 4 is thrown to the position of a character contour correction section 2. The character contour correction section 2 corrects the density of a notice picture element into an intermediate density when, e.g. the notice picture element corresponds to a ridge of a slant of a character contour. Thus, the jaggy of the slant of an image is corrected to be unremarkable. On the other hand, when image information and valid data of the matrix data are dissident, the changeover circuit 4 is thrown to the position of a smooth section 3. The smoothing section 3 corrects the density of the notice picture element based on surrounding picture elements. Thus, the discrimination processing between a character image area and a picture image area of a binary image having been executed conventionally is not required.

Title: Semiconductor integrated circuit
Inventor: KATO YUKIHIRO
IPC: H01L21/822
Filed: 1989-10-27
Abstract: PURPOSE:To reduce dropouts of signals at high frequencies by providing an insulated isolating region for electrically isolating an embedded layer at the lower part of an input pad and an embedded layer at the lower part of an output pad. CONSTITUTION:An input/output isolating region 16 comprises an insulator which is arranged so as to divide a silicon semiconductor substrate into two parts. The region 16 is formed by providing a groove 17 so as to divide an embedded layer 2 in the semiconductor substrate 4, forming an oxide film 18 of a groove- side wall on the groove 17 and thereafter filling the groove 17 with an insulator 19. Therefore, the embedded layer 2 is divided between an input bonding pad 7 and an output bonding pad 12 as shown by resistors Rb1 and Rb2. A resistor Rt and capacitors Ct1 and Ct2 of the input/output isolating region 16 are present between both pads. The capacitance and the resistance of a substrate 1 are divided into Cs1, Cs2, Rs1 and Rs2. The resistance of the insulator 19 of the input/output region 16 is largely higher than the resistance of the embedded layer 2. Therefore, the impedance between the input and output bonding pads 7 and 12 becomes largely high, and the dropouts of the signals becomes less.
