Title: Test system for transmission line
Inventor: SHINOHARA KAZUO
IPC: G06F11/22
Filed: 1987-08-21
Abstract: PURPOSE:To improve the processing capability of the entire network by identifying the normality of the transmission line in the transmission range of a test frame to be transferred to a directly coupled node processor within a prescribed period and identifying the other as a fault so as to process the frame in a short time. CONSTITUTION:In the test frame, an address DA of a destination node processor, an address SA for a sender node processor, a control code CTL displaying kinds of transfer information, a data DATA and a frame check sequence FCS for error control by the CRC system are sent sequentially in succession to a flag F for frame identification consisting of a prescribed bit pattern and a flag F for frame identification is sent finally. A processor 1-1 discriminates all the transmission line normal, connecting node processors 1-1-1-4 and a common transmission line 3 together only when the test frame is transferred within a prescribed period after the transmission on the test frame. Thus, the transmission line is tested in a short time efficiently.

Title: Controller for motor
Inventor: YOKOUCHI HIDEYA
IPC: H02P7/29
Filed: 1984-10-03
Abstract: PURPOSE:To control the rotating speed of a motor with high linearity for the duty of a speed command signal by alternately switching two charging resistors by the mark and the space of the speed command signal. CONSTITUTION:A transistor 2d is turned ON by the mark of a speed command signal, and charging is started by a charging resistor r1 through the first resistor 2b. A transistor 2e is turned ON by the space, and charging is started by a charging resistor r2 through the second resistor 2c. In the charging step, the resistors 2b and 2c are alternately switched in response to the duty of the speed signal. The value R of the charging resistor is linearly proportional to the duty. As a result, the rotating speed is proportional with high linearity for the duty of the pulse width modulation signal.

Filed: 1984-10-03
Abstract: PURPOSE:To remove a backlash in an engaging section of respective gears with a simple construction by applying a force of an intermediate gear for transmitting a force from a motor to a rack in the direction of engaging of teeth. CONSTITUTION:A intermediate gear wheel 3 and an intermediate pinion 4 are movably supported in the direction of an arrow 10 and pressed in the direction of an arrow 11 by a pressurization spring 5. By pressing in the direction of the arrow 11 by means of spring force, to the intermediate gear wheel 3, a moment having a fulcrum of the intermediate pinion 4 operates and is pressed to the pinion 2. Thereby, the back lash between the pinion 2 and the intermediate gearwheel 3 is removed. In the same manner, since the intermediate pinion 4 is pressed towards a rack 6 by a moment having a fulcrum of the intermediate gear wheel 3 due to a spring force, the back lash between the intermediate pinion 4 and the rack is also removed. A wear due to an use for a long period is absorbed by approaching the intermediate gear wheel 3 or the intermediate pinion 4 respectively to the pinion 2 or the rack 6 to maintain a condition having no backlash.

Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a packing tape body which is easy to pack and unpack and can be recycled. SOLUTION: A packing tape body 10 is provided with carrier tape 11 in which QFP.IC storage cavities 14 are arranged longitudinally, and lids 12 for covering the openings of the cavities 14. On female hinges 19 formed at the right and left sides of the opening of each cavity 14, male hinges 23 formed at the outside ends of the right and left rids 12 are supported so as to be freely turnable, and the right and left lids 12 are integrated with the carrier tape 11 so as to open/close the opening of the corresponding cavity freely.

Title: Rolling method for steel products
Inventor: MASUDA KENICHI
IPC: B21B1/22
Filed: 1985-09-20
Abstract: PURPOSE:To smooth the war of work rolls having shifting and bender means and to maintain steel products at the required crown accuracy by controlling a shift range according to the need for a low crown in rolling of the steel products by the work roll pair having the shifting and bender means. CONSTITUTION:The work rolls 12, 14 grasped under the pressure by backup rolls 22, 28 are shifted by hydraulic cylinders 16, 18 of chocks 32, 36 supporting both end shafts 33, 35. The spacing between the shafts is spaced by the oil pressures of benders 38, 39, 40, 41 provided to the chocks 32, 36 to decrease the crowns of the work rolls 12, 14. The steel products for which the low crown is not required are smoothed in the wear as far as possible by shifting the work rolls 12, 14 in a wide range. The crown of the steel products for which the low crown is required is decreased by shifting the work rolls back and forth around the max. shift position to substantially act the bender force of the work rolls 12, 14. The steel products are thus formed to have the low crown by smoothing the work rolls 12, 14.

Title: Laser marking method
Inventor: KATO HARUO
IPC: H01L23/00
Filed: 1990-08-08
Abstract: PURPOSE:To enhance the definition of a mark at a low cost by a method wherein, when the surface of a package is irradiated with a laser beam and a prescribed mark is formed, the laser beam is irradiated from a direction which is oblique to the marking face of the package. CONSTITUTION:A laser beam L radiated from a laser radiation part 10 with a built-in light source of carbonic acid gas or the like is reflected, by a reflecting mirror 11 arranged in the halfway part of a light path, to a direction which is oblique to the marking face of an LSI package 1. After that, the beam is converged by using a condensing mirror 12 arranged between the reflecting mirror 11 and the LSI package 1 and reaches the marking face. When the laser beam L is irradiated from the direction oblique to the marking face, the inside wall of a carved groove 13 is inclined with reference to the marking face, and angles of reflected light are different between the inside and the outside of the groove 13. As a result, the contrast between the marking face and a mark becomes clear when the marking face is viewed from the upper part; and the definition of the mark is enhanced.

Filed: 1983-11-09
Abstract: PURPOSE:To detect a defect with high accuracy by detecting the defect on the basis of the waveform of currents flowing through a thin-film conductor by flowing currents of maximum permissible currents or higher through the thin- film conductor and applying voltage, pulse width thereof is limited. CONSTITUTION:Pulse voltage VP is applied to a thin-film conductor in a sample 14 from a pulse generator 13.

Pulse width is set that the Joule heat generated in the thin-film conductor through the application of pulse voltage VP in an extent that a novel defect is not generated in thin- film conductor itself and sample 14 itself. The resistance value of the thin-film conductor slowly increases by Joule heat generated in thin-film conductor itself and a waveform is not disturbed when there is no defect in the thin-film conductor, but the waveform is disturbed when there is the defect. Accordingly, the defect can be detected accurately without being controlled by the limit of thermal stress.

Title: Stabilizing treatment of radioactive waste
Inventor: MATSUURA HIROYUKI
IPC: G21F9/08
Filed: 1990-08-09
Abstract: PURPOSE:To enable producing a solidified body which is favorable for safety evaluation thereof by adding a sodium carbonate to a radio-active liquid waste, by applying pretreatment that is to change carbonate ion of a radioactive nuclide, C-14, which exists in a soluble condition in the liquid, to a calcium carbonate, by a slake lime or a quick lime as well as to refractory carbonate, at the same time, and also by applying drying-up treatment and solidification. CONSTITUTION:Concentrated readioactive liquid waste is pre-treated by a sodium carbonate. Soluble cabonate ion existing in a form of a sodium cabonate in the liquid waste, is changed to a calcium carbonate and to a refractory condition into water. However, since an amount of the carbonate ion containing a radioactive nuclide, C-14, is extremely small, the cabonate reaches its solubility and therefore there is some possibility to be dissolved into water, even if such a pre-treatment is applied. Accordingl, a sodium carbonate is previously added to the extent that the solubility of the calcium carbonate is well exceeded, and there with the carbonate ion containing the nuclide, C-14, co-precipitates with the added carbon ion ad then can be changed to almost insoluble one into water. Finally, the ion is treated by a plastic solidification process or a pelletizing treatment.
