IPC: G06F1/08
Filed: 1985-09-30
Abstract: PURPOSE:To reduce the load of a programmer by providing a clock selecting circuit and a clock switching program and giving the dynamic change to the clock speed at the part of a software timer. CONSTITUTION:Both clocks A and B are supplied to a clock selecting circuit 1 via lines 2 and 3 respectively and either one of both clocks is usually delivered through a line 5. When the input clock is changed, the control signal SEL of a line 4 is allocated to a certain port address. Then an access is given to the relevant port by a program and the signal SEL is inverted. In other words, the count frequency is set at a part equivalent to a timer (loop) by a prepared program and an access is given to the port to which the circuit 1 is allocated. Then this port is switched as necessary to the logic clock obtained when the program is designed. Thus the clocks are fixed during an actual loop and the replacement of programs is omitted. As a result, the load of a programmer is reduced.

Title: Focus error detector for optical disk head
Inventor: FUJITA TERUO
IPC: G11B7/123
Filed: 1984-10-16
Abstract: PURPOSE:To attain the miniaturization with small thickness for an optical disk head by providing two diffraction gratings on or inside a thin film optical waveguide path or at an interface between said waveguide and a substrate and then setting a photodetector for focus error and primary signal on the optical waveguide path or the end face of said waveguide path. CONSTITUTION:When an information recording surface 9 in set above a condensing point 6 and at a position distance away from the point 6 by DELTA1, the reflected light 25 sent from the surface 9 is converted into the waveguide light 19 with the maximum efficiency by a diffraction grating 18. In this case, however, the excitation of the waveguide light 15 is weak and the quantity of light applied to a photodetecting element 20 of a 2-split photodetector 16 is increased. When the point 6 is set on the surface 9, the connection between the light 25 and light 15 and the light 19 is incom plete respectively. Thus both light 15 and 19 are excited with almost same strength, therefore, both photodetecting elements 17 and 20 have about an equal incident light quantity. When the surface 9 is set under the point 6 with the distance DELTA1, the light 15 has the most intensive excitation by the light 25. Then the quantity of light made incident on the detector 16 is maximum. In such a way the miniaturization with small thickness is attained for an optical disk head. Then the control of the optical axis is facilitated with a photodetector.

Title: Immersion nozzle and continuous casting method using this nozzle
Inventor: MURAKAMI TOSHIHIKO
IPC: B22D41/50
Filed: 1988-08-30
Abstract: PURPOSE:To uniformize the thickness of the molten powder pool in a meniscus part generated by electromagnetic stirring by using an immersion nozzle having fins inclined in the perpendicular and circumferential direction of the nozzle at a specified spacing on the outer peripheral surface. CONSTITUTION:The fines 3 incline at an angle beta in the perpendicular direction and, therefore, rising force is generated in the direction of the component of force F1 of stirring force F when a molten metal receives the force F. Since the surfaces of the fins 3 receiving the stirring force F incline with the circumferential of the nozzle body 2, flow is generated in the direction of F2. The composite force of F3 is acted on the molten metal by this rising force and flow. The immersion nozzle 1 having the fins 3 at specified intervals on the outer peripheral surface is, therefore, disposed in a casting mold in such a position where the fins 3 exist at the height of the molten metal level in the casting mold. The molten metal is then poured into the casting mold 4. The molten metal 5 is lifted by the composite force F3 when the molten metal 5 poured into the casting mold 4 is stirred by an electromagnetic stirrer 6. The height of the molten metal level between the immersion nozzle 1 and the casting mold 4 in the meniscus part is, therefore, approximately equaled and the molten pool thickness of the powder is uniformized.

IPC: G06F1/04
Filed: 1994-09-12
Abstract: PURPOSE: To reduce the power consumption accompanying the operation of a CPU when the CPU is in an during the term of a standby state at the time of an for operation during the term of a standby state at the time of an I/O access mode or at the time of a hold stat during the time when a direct memory access (DMA) operation mode is executed. CONSTITUTION: A DMA controller 2 outputs a hold request signal (HOLD) to a CPU 1 in order to release a system bus from the CPU 1 and to possess its use right. From the reception of a hold agree response (HOLDA) to the cancel of HOLD, the controller 2 outputs a clock stop signal (CLS) to a clock control circuit 6. The clock control circuit 6 stops supplying an operating clock (CP) to the CPU 1 corresponding to the input of CLS. Thus, since the supply of CP to the CPU 1 is stopped by the controller 2 during the execution of the DMA operation mode, the power consumption due to the operation of the CPU 1 can be reduced.

Title: Manufacture of magnetic bubble element
Inventor: OBARA TAKASHI
IPC: G11C11/14
Filed: 1983-11-21
Abstract: PURPOSE:To preclude generation of a potential difference between adjoining conductors and to prevent electro static breakage of conductors by providing connecting wiring between conductors and connecting said wiring by passing through a cutting area of a wafer. CONSTITUTION:A common line 6 is arranged in a scribe area 5 surrounding a pellet shown by a hatched line, in order to conduct all conductors, and a wiring 8 to couple the common line 6 is formed in the nearest location from each conductor 7 and from the location where the wiring 8 does not intersect with other wiring. By conducting other conductors in such a way, generation of potential difference and electro static breakage can be prevented. Since the common line is arranged in the scribe area, the common line is scraped at the time of cutting a wafer, and conduction between conductors is eliminated; therefore there is no trouble at the time of using a chip. When an element is constituted in such a way that plural blocks are made into one chip, the common line is arranged by entering an area in which a wafer is cut.
