Title: Manufacture of rare earth group permanent magnet
Inventor: AKIOKA KOUJI
IPC: B22F1/02
Filed: 1984-04-13
Abstract: PURPOSE:To improve magnetic characteristics, particularly an energy product, coersive force bHc, heat resistance by executing the processings after previously forming an oxide film of a particular thickness in the heat processing required for manufacture of rare earth group permanent magnet. CONSTITUTION:Before high temperature heat processing of a rare earth group magnet, an oxide film in the thickness of about 500-3,000Angstrom  is formed by executing the processing for the period within 1min-1hr at a temperature of 200- 400 deg.C as the auxiliary processing. Thereafter, the predetermined heat processings are carried out. Since an oxide film is formed, vaporization of R element must be carried out through the oxide film and therefore the vaporization process is interfered remarkably. Therefore, change of composition by vaporization of R element which has been a factor for rejecting high performance can be prevented and a high performance magnet can be obtained.

Title: Heat generating recording device
Inventor: YASUMI KUNIO
IPC: B41J2/355
Filed: 1980-06-02
Abstract: PURPOSE:To lengthen the life of a heat-sensitive head by bringing one section of a current controlling means to a high impedance condition interrupting the recording energizing currents of a group connected to the one section of the means when the number of the recording energizing heat generating sections exceeds a fixed number. CONSTITUTION:When the values of a resistor RB1 and a resistor RA1 are set at fixed values because the voltage of the RB1 is the base voltage in the forward direction of a transistor QS2, the transistor QS2 is at ON when the number of the ON of the first pair switching circuits 51-5216, the number of recording picture elements, is a fixed number or more and is at OFF when the number is less than the fixed number. Even when a transistor QS1 is made ON and energized by the output of a group selective circuit 2, the transistor QS2 is at ON and a section between a base and an emitter of the QS1 is short-circuited when the number exceeds the fixed number, thus resulting in no ON of the transistor QS1. Consequently, the recording energizing currents do not flow through the heat generating sections R1-R216 when the number of the recording picture elements exceeds the fixed number. The transistor QS1 is at ON by the output of the group selective circuit 2 when the transistor QS2 is at OFF, and the recording energizing currents flow through the heat generating sections connected to the ON circuits among the switching circuits 51-5216.

Title: Semiconductor device and al wiring structure for vlsi and its manufacture
Inventor: ONUKI HITOSHI
IPC: H01L21/321
Filed: 1989-03-27
Abstract: PURPOSE:To prevent the disconnection failure of a wiring and improve reliability by a method wherein a wiring film is constituted of an Al alloy film having bump structure, and the azimuth of each crystal grain of the bump structure is mutually oriented by the inclination less than or equal to 10 deg.. CONSTITUTION:On a semiconductor substrate 1, a diffusion layer 2 and insulating layers 3, 5 are arranged; by sputtering method or the like, Al alloy layers 4, 6 are formed on the insulating layers 3, 5; said alloy layers 4, 6 are constituted of bump structure. The size of inclination between crystal grain boundaries of bump structure is proportional to the size of defect of grain boundary. As the inclination of grain boundary becomes small, each grain boundary tightly combines, and grain boundary diffusion is hardly caused, so that disconnection is hardly caused. in particular, when the inclination of each crystal grain is less than or equal to 10 deg., the protection effect of grain boundary diffusion becomes remarkable. When the inclination angle becomes larger than or equal to 10 deg., the failure rate sharply increases. By keeping the inclination angle less than or equal to 10 deg., a highly reliable VLSI can be obtained.

Title: Controller for running course of trackless vehicle
Inventor: YOSHIDA YUTAKA
IPC: G05D1/02
Filed: 1979-06-15
Abstract: PURPOSE: To provide easily a safe control circuit in a controller of a vehicle such as a crane truck, a truck which travels along an inductive cable by a method wherein a positional deviation signal is input into the primary lag circuit and a track-correction signal is output through the deviation from the specified value by comparing them with each other.  
     CONSTITUTION: The deviation from an inductive cable 21 laid under the ground is detected by a detector 19. A positional deviation output signal 22 is input into a primary lag circuit 23 and subtracted in a subtractor 24. As a result, the output of an amplifier 25 becomes equivalent to the positional deviation in a given time and this amount makes the factor indicating an approach angle to the inductive cable 21. When the approach angle is small but an early positional deviation is large, the deviation output signal 22 and the amplifier output 25 are added in an adder to make a positional correction signal. This signal is input into a comparator 27. When it exceeds a specified value it is used as a relay P output 28, an N output 29 to change over the magnetic field of a drive motor 18 and to carry out positional correction.
