Title: Semiconductor rectifier
Inventor: MORI MUTSUHIRO
IPC: H01L29/10
Filed: 1981-09-18
Abstract: PURPOSE:To manufacture the thyristor with high dv/dt withstand voltage wherein the lateral resistance is controlled to increase at room temperature decreasing at high temperature with less arc sensitivity by a method wherein the material with high resistance at room temperature and low resistance at high temperature is utilized. CONSTITUTION:CTR 100 is provided in PB layer adjoining the side of NE layer. CTR 100 being subject to high resistance at room temperature, the gate current flows into the cathode electrode 5 through PE layer under the CTR 100. Therefore the lateral resistance may be increased up to R1+R2 higher than R of the conventional thyristor improving the arc sensitivity (IGT). On the other hand, CTR 100 being subjected to low resistance at high temperature, the gate current flows into the cathode electrode 5 through the CTR 100 making the lateral resistance R1 lower than R of the conventional thyristor to improve the dv/dt withstand level at high temperature. With VO2 with 200KOMEGA accumulated on the thyristor up to approximate 10mum at room temperature as CTR 100 by means of sputtering as shown in the drawing, the arc sensitivity IGT and the dv/dt withstand voltage may be respectively increased exceeding twice.

Title: Corrosion resistant hafnium
Inventor: KUWAE YOSHINORI
IPC: C23F15/00
Filed: 1983-08-12
Abstract: PURPOSE:To obtain corrosion resistant hafnium having superior resistance to nodular corrosion and preventing hydrogen embrittlement by specifying the surface roughness of hafnium. CONSTITUTION:The surface roughness Ra of hafnium is adjusted to <=1.5mum. When this hafnium is used as a metallic material requiring corrosion resistance such as the material of a control rod for a nuclear reactor or a structural material for a chemical apparatus, it shows superior performance for a long term and does not undergo deterioration due to nodular corrosion. Since the volume of gaseous H2 produced is reduced, hydrogen embrittlement due to the formation of hydride is inhibited.

Title: Acceleration slip control device for car
Inventor: INAGAKI TAKAFUMI
IPC: F02D41/22
Filed: 1985-07-04
Abstract: PURPOSE:To suppress recurrence of acceleration slip by furnishing a target opening setting means which is to set the target opening of a throttle valve on an acceleration slip control means on the basis of the difference between the drivewheel speed and reference speed. CONSTITUTION:The reference speed for a drive wheel M2 is calculated M3 on the basis of the car running speed sensed by a speed sensor of an idling wheel. The revolving speed of drive wheel M3 is sensed M4 from a drive wheel speed sensor. Therefrom the acceleration slip is sensed, and it is suppressed by driving a throttle valve M7 in the direction of closing. When the throttle valve M7 is driven again in the direction of opening, the target degree of opening is set M9 on the basis of the difference between the drive wheel speed and reference speed. This ensures that the degree of opening of the throttle valve M7 is suppressed in accordance with the magnitude of slip, which will serve suppression of recurrence of acceleration slip.

Abstract: PURPOSE:To improve the reverse conduction and switching characteristics by a method wherein difference is formed betweeen the resistivities of a diode part and a thyristor part at the time of the resistance adjustment for silicon as the base material by neutron irradiation method. CONSTITUTION:A reverse conduction thyristor is constituted by integrating the thyristor part 2 composed of a P-N-P-N layer and the diode part 1 composed of a P-N layer in reverse parallel in a piece of Si plate.

In other words, first the Si plate is so irradiated uniformly as to be provided with resistivity required for a diode. Next, only the thyristor part 2 is irradiated with thermal neutron, resulting in adjustment for the resistivity required for a thyristor.

Title: System for reducing pieces of information which are transmitted with the representation of coded value and string length as well as coded variable length of value data block
Inventor: RUIGI RONKETSUTEI
IPC: G06T9/00
Filed: 1990-06-07
Abstract: PURPOSE: To reduce the number of symbols to be transmitted by each block by transmitting all of N continuous strings, which are preceded by the execution length of a classical type and follow another execution length or a block end signal at the time when N-1 strings are formed. CONSTITUTION: When N=1, no value is transmitted. This does not bring about the loss of data. For example, a message M2 shown in the figure is transmitted as a message M4. The comparison between M4 and M3 clearly shows that numbers '1' (positive) are not transmitted, if they are isolated by two execution lengths (in the case of (a) and (b)) or if they are the last number of strings included between two execution lengths (in the case of (c)) or if they are the last number of the string after an execution length and follow the block end symbol (in the case of (d)). Therefore, it is sufficient is slight combination sequential logic elements which divides zeros into groups to calculate the execution length are introduced into the traditional processor.

Title: Printer
Inventor: KARUBE YOSHIYUKI
IPC: B41J25/308
Filed: 1990-06-05
Abstract: PURPOSE:To obtain a stable, high quality print regardless of the temperature rise of a print head by a method wherein a print gap adjusting mechanism is controlled so that the print gap is automatically changed corresponding to changes in the temperature of the print head. CONSTITUTION:The print gap changes as the temperature of a print head 2 rises, however, a central processor 17 calculates control signals and controls a gap adjusting drive circuit 38 with the control signals so that the change amount of the print gap is corrected to a proper value. For example, when a limit switch 27 detects that paper absent state changes to paper present state, a step motor 9 is operated until the tip of the print head 2 comes in contact with a sheet of recording paper 15, causing the step motor 9 to be overloaded, and after that, the step motor 9 is stepped backward by specified steps so that a proper print gap is maintained between the print head 2 and the recording paper 15. As the temperature rise of the print head 2 is nearly proportional to the total number of dot pin motions, the temperature is rise value can be estimated through arithmetic processing. The central processor 17 inputs control signals to the gap adjusting drive circuit 38 corresponding to the estimated temperature rise so that the print gap is always kept constant.
