Title: Discriminating device for movement of unmanned carrier
Inventor: KATAOKA KATSUNOBU
IPC: G05D1/02
Filed: 1987-06-01
Abstract: PURPOSE:To easily confirm an initial running angle by reading the position code of a rotary plate which turns in response to the difference between the speeds of two driving wheels via a detector and using said position code to change the driving angle of an unmanned carrier for display of the driving angle output. CONSTITUTION:When a control circuit 1 for a movement deciding device of an unmanned carrier 2 is actuated, the code of a rotary plate 2c is first detected by a detector 2d and the pulse of the detected code is supplied to a RAM 1c via an interface 1e. Then the conversion of the running angle is carried out for the output received from the detector 2d by means of a program stored in a ROM 1b. The display signal thus obtained is outputted to a display means 3 via an interface 1d. Thus an operator can easily decide the moving direction of the carrier 2 with reference to the movement information on the means 3.

IPC: H01L21/208
Filed: 1988-06-03
Abstract: PURPOSE:To prevent the generation of inflection by a method wherein, when a Ga1-xAlxAs epitaxial layer is formed on the surface of a GaAs substrate, a Ga1-xAlxAs epitaxial layer, whose Al mixed crystal ratio is larger than that of the layer on the surface, is formed on the rear of the GaAs substrate. CONSTITUTION:When the Al mixed crystal ratio of a Ga1-xAlxAs epitaxial layer 10 is larger than or equal to 0.4, and the layer thickness is larger than or equal to 100mum, a Ga1-xAlxAs epitaxial layer, whose Al mixed crystal ratio is larger than that of the Ga1-xAlxAs epitaxial layer 10 formed on the surface of a GaAs substrate 1, is formed on the rear of the GaAs substrate 1. Thereby, the inflection of wafer can be remarkably reduced, even when the Al mixed crystal ratio is large, and the film is made thick.

Filed: 1989-05-31
Abstract: PURPOSE:To satisfactorily prevent a stripe pattern from being generated by the difference of a characteristic in plural sound ray processing parts by providing an image forming means, etc., to form an image according to the set of averaged sound ray signals. CONSTITUTION:In a frame memory 11, the sound ray signal to be inputted to an odd-number input port (o) and the sound ray signal to be inputted to an even-number input port (e) are successively put in order and one frame of the image is constituted and stored. The stored frame is further shifted to a frame memory 12 and the next frame is constituted and stored. In an average calculating part 13, the frames stored in the frame memories 11 and 12 are averaged and the new frame is made and stored in an image memory 14. Since an image processing part 7 averages the two frames, averaged images G1-G4 can be successively obtained and displayed on a CRT 8. Thus, even when these is the difference of the characteristic between both sound ray processing parts 3 and 4, the difference does not appear on the screen of the CRT 8 at all.

Title: Compressing and extending device of program play time
Inventor: KONDOU SHIGEYUKI
IPC: G11B15/467
Filed: 1982-08-09
Abstract: PURPOSE:To eliminate the dissidence between the material time and the play time, by executing stably the variation from an extremely low tape speed to a comparatively high tape speed. CONSTITUTION:S1 means a signal which is displayed by the difference between the material time and the play time, the ratio of the play time, and a code. A block 1 delivers a tape speed variable signal + or -DELTATD and a reference signal variable varying signal + or -DELTATP. A means 2 supplies the signal + or -DELTATP and then delivers a signal S2 through a constitution shown in the diagram, where alpha of the S2 is shown as alpha NPXDELTATD/TP. A delay means 5 delays a capstan tack signal by TC(ND+ or -beta), where TC is the clock cycle of a clock generator 5-3, ND is a fixed value and beta DELTATD/TC respectively. A block 4 receives the delayed and nondelayed signals and generates the speed voltage corresponding to the tape speed. The delayed signal is variably controlled by a signal + or -DELTAD. A block 3 compares in phase the reference signal S2 and the control track signal of a block 7. The output of the result is added with the output of a block 4 and fed to a driving amplifier 8.

Abstract: PURPOSE:To allow magnetic lines of force to pass magnetism impressing materials having high magnetic permeability and to suppress the density of the magnetic lines of force in a position to be worked by disposing said magnetism impressing materials near a blanking hole. CONSTITUTION:The magnetism impressing materials 9 and springs 10 are disposed in the holes penetrating die sets 1, 2, packing plates 3, 4, a punch holder 5, and a stripper 6. Since the materials 9 are parted from the actuation position of the punch, the materials bend the direction of the magnetic lines of force passing the same and have the function to suppress the density of the magnetic lines of force to be applied to a metallic plate 15 to be worked as far as possible. The materials 9 are constituted of the material having high magnetic permeability such as 'Permalloy(R)' and the plate-shaped metal 15 to be worked is of pure iron, carbon steel, etc. The condition of the magnetic lines of force generated at the time of pressing is as shown by arrows and the magnetic lines of force are bent near the peak part 8 of the blanking punch 7, by which the density of said lines is suppressed. The floating of the slug of the pressing stage by the magnetic lines of force is prevented in this way and the blow marks are suppressed. The appearance grade of the product is thus improved.
