Title: Data demodulation circuit
Inventor: KOMENO FUMIO
IPC: G11B7/00
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a magneto-optical disk device for high density by dispensing with the need of the DC coupling of a signal and a special signal correction processing. SOLUTION: A pulse signal generation circuit 14 is operated in a PWM mode or a PPM mode based on the inputting of a mode signal MP. At the time of the PWM mode, the circuit 14 makes binary data S12 by a zero cross detecting circuit 12 a signal S14a in the level signal of as-inputted level signal to output it to a second phase comparing circuit 23 via a first phase comparing curcuit 18 and an inverter 25 and generates a pulse signal 14b having a pulse width corresponding to the operating mode to output it to a data discriminating circuit 15 and an incoming signal generating curcuit 16.  Moreover, at the time of the PPM mode, the circuit 14 does not output the binary data signal S12 but outputs, for example, the signal S14a of a constant level, for example, a power source voltage Vcc to the second phase comparing circuit 23 via the first phase comparing circuit 18 and the inverter 25 and generates the pulse signal S14b having a width corresponding to the operating mode to output it to the data discriminating cirucit 15 and the incoming signal generating circuit 16.

Title: Focus servo circuit for optical disk drive device
Inventor: MORIWAKI ISAMU
IPC: G11B7/085
Filed: 1991-02-05
Abstract: PURPOSE:To stabilize the retraction of focus by controlling the moving speed of an objective lens so that the relative speed between the objective lens and an optical disk can be set constant. CONSTITUTION:By setting the optical disk to the device, the focus servo circuit drives a focus motor with a driving signal S1 with chopping wave-like wave. By this, an objective lens 11 is moved up at a constant speed and then moved down. A control part 7 detects the fall of output signals from a wind compartors 4 and 5 and a zero cross comparator 6, and then detects the moving time required for the lens 11 to move from a focussing position on the surface of a circuit board to the focussing position on a recording film. Then the control part 7 measures the relative moving speed of the lens 11 and outputs the signal S1 so that the moving speed can be kept constant.

Title: Vane wheel for pump
Inventor: SUDO SUMIO
IPC: F04D29/24
Filed: 1986-02-21
Abstract: PURPOSE:To prevent the generation of cavitation by cutting a groove in the direction of steamline on the front edge part along the front edge part of a vane and forming the inlet angle of the groove smaller than the inlet angle of the part other than the continuous groove and preventing the exfoliation of the flow in the groove part. CONSTITUTION:The flow passing through a vane wheel 1 is sucked in the direction of arrow, and blown out. A groove 1e directed in the direction of stream line is cut on the front edge part 1d along the front edge part 1d of a vane. The shape of the groove is determined so that the inlet angle beta1' of the groove 1e is made smaller than the vane inlet angle beta1 of the part other than the continuous groove 1e. Since, when the vane wheel is operated with the partial flow rate, the vane inlet angle beta1' of the groove part 1e is prevented, and the flow is introduced along the vane negative pressure surface. Therefore, the cavitation generated on the outer peripheral side in comparison with the groove 1e side is suppressed, and the generation of noise, vibration, and erosion are prevented or suppressed.

Title: Semiconductor device
Inventor: KITAMURA FUJIO
IPC: H01L23/31
Filed: 1987-02-17
Abstract: PURPOSE:To make the stress of a sealing resin low without impairing humidity resisting reliability, by using an epoxy resin composition, wherein an epoxy resin having a specified composition is included by 5-50 wt.% of the entire epoxy resin, and sealing-in a semiconductor element. CONSTITUTION:A specified epoxy resin expressed by the Formula I is a multifunctional epoxy resin, wherein the part of O-(R1O)n-at a pendant part in a molecular structure is a structural part having high flexibility. Said resist is used by 5-50% of the entire epoxy resin. Thus an epoxy-resin molded body, which is characterized by high bridging density and high flexibility, can be formed. When the amount of inclusion of the specified epoxy resin expressed by the Formula becomes less than 5%, low stress property becomes insufficient. When 50% is exceeded, heat resistance and humidity resistance become poor. In the Formula: R1 is a bivalent organic group, whose number of carbon atoms is 2-3; R2 is a hydrogen atom or a methyl group; (m) is an integer in the range of 0-15; and (n) is an integer in the range of 1-12. Since the plastic package has the excellent low stress property and the high humidity resistance reliability, the reliability of the device is improved.
