Title: Optical reproducing device
Inventor: INOUE KYOICHI
IPC: G11B7/09
Filed: 1987-08-05
Abstract: PURPOSE:To improve the stabilization of a focusing servo system to a disk defect by changing a focus offset voltage to a prescribed value while the defect is detected when the defect of the disk is detected. CONSTITUTION:A beam from an optical pickup 14 passes through the disk defect in a condition that the focusing servo is supplied, a beam reflecting light from a disk 12 is omitted and the RF signal of an RF detecting circuit 26 is omitted. A defect circuit 28 detects the disk defect and outputs a defect DF signal to an input terminal INDF of an offset canceling circuit 25. At the circuit 25, when the terminal INDF goes to an H, a transistor Q1 is turned on and an offset adjusting voltage VFO of a focus error detecting circuit 22 is made into a zero. Thus, the focus error FE signal output of the circuit 22 also goes to the zero and the output of the amplifier circuit 34 does not change. For this reason, while passing through the defect, a driving voltage just before the defect is inputted to a focus coil 16 and an objective lens does not move carelessly.

Title: Manufacture of semiconductor device
Inventor: KUNO JUNICHIRO
IPC: H01L21/265
Filed: 1986-08-19
Abstract: PURPOSE:To prevent discharge between a mask pattern and a semiconductor substrate and to prevent breakage of a thin oxide film or the like, by providing a conductive thin film between the mask pattern and the substrate before implanting dopant ions. CONSTITUTION:An aluminium film 5 as a conducting film is deposited over the entire surface of an MOS transistor Tr including a field oxide film 2 on a semiconductor substrate 1. Resist G is then formed selectively and boron ions for example are implanted in the entire surface. The boron ions do not reach the substrate 1 through the resist 6, field oxide film 2 and a gate electrode 4 because they are trapped. However, a part of charges of the ions escape through the film 2 to a clamp suporting the substrate 1. Even if charges are stored in the resist 6, no discharge is caused between the resist and the substrate 1 since the film 5 has a field shielding effect and, hence, there is no possibility of breaking the gate oxide film 3. Further, the boron ions are implanted into source/drain regions of the MOS transistor through the film 5 and diffusion layers 7 are formed in said regions.

Title: Screw for pile installation by inner excavation
Inventor: MACHINAGA KAORU
IPC: E02D7/00
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To enable inner excavation of a pile having a small diameter by providing a plural winding screw blade, a central shaft like a double pipe, and a cemented tip edge tip and specifying their dimensions. SOLUTION: A screw 1 is provided with a plurality of blades 2, and a ratio of screw pitch P to outside diameter D of the screw is 2 to 8. The blade 2 cooperates with a shaft 3 to transmit effective twisting moment, and the pile installation by inner excavation of a pile having a small diameter becomes possible because it transmits a large torque even if its diameter is small. A fish tail 10 with cemented tip is attached to a head part 7 to enable digging of hard rocks. The length of the head part 7 is 1.5 meters or more so that a joint exists in the pile even if a bit receives a large bending force when a bulb is produced in a lower part of the pile and local stress does not act in the joint part. The central shaft 3 is a double pipe and is used in the digging due to low pressure air for discharging digged soil and high pressure fluid, stirring, pouring of cement milk, etc. Moreover, if an outside diameter of the pile having a small diameter is 450mm, its outside diameter D is 250mm or less.

Title: Producing device for single crystal of high dissociation pressure compound for semiconductor
Inventor: TOMIZAWA KENJI
IPC: C30B15/00
Filed: 1981-12-04
Abstract: PURPOSE:To produce titled single crystals with good crystallinity and mass productivity and with feasibility of an increase in diameter economically by covering the  melt of a high dissociation pressure compd. with the melt of boron oxide, and rotating  and pulling the same in an atmosphere of volatile component constituting the high dissociation pressure compd. CONSTITUTION:A rotating and pulling shaft 6 is brought down to bring a seed crystal  12 into contact with the melt 8 of a high dissociation pressure compd, then while the  shaft is rotated, the shaft is pulled up to grow a single crystal 15. The single substance 19 of the volatile components in a receiving tray 18 is heated and evaporated by an  after heater 3, by which an atmosphere of the volatile components is created in a  furnace core pipe 17. Therefore, the degradation of the crystallinity near the surface  by the dissociation of the volatile component from the surface of the single crystal  grown 15 is obviated. Since the melt 8 is coated with the melt 16 of boron oxide, the  evaporation from the melt 8 is suppressed, sticking on the inside surface of the pipe 17  is decreased and observation is made easy. Even if deposits drop, the deposits fall onto  the covering melt 16; therefore, the growth of the single crystal is not interfered and  the rate of single crystallization is improved.

Abstract: PURPOSE:To prevent the occurrence of a slip and to perform reliable starting by engaging the pinion of an input output shaft with the internal tooth of a ring gear in a state that the ring gear and a friction wheel combined together on both the input and the output shaft side are brought into a maximum eccentric state. CONSTITUTION:A pinion 7 on the input shaft 4 side is engaged with an internal tooth 12 of a ring gear 11 in a position where a shift frame 21 is moved to a rightmost end, and inverted conical surfaces 14 on both sides of the ring gear 11 are brought into linear contact with each other in a position nearmost to the centers of friction wheels 15 and 15.

Rotation of the input shaft 4 in this state is decelerated to the ratio of the number of teeth of the pinion 7 to the number of teeth of the internal tooth 12 and transmitted to the ring gear 11. The rotation is transmitted as the same rotation in the same direction to the ring gear 11a through an idle gear 25, and the number of revolutions of the output shaft 5 is reduced to a minimum, which is outputted through the friction wheels 15a and 15a.

Title: Semiconductor integrated circuit
Inventor: MINE HIROTOSHI
IPC: H03K17/04
Filed: 1992-07-22
Abstract: PURPOSE:To prevent a delay in a signal propagating time in a succeeding stage circuit by making the output amplitude of a high load drive circuit higher than source voltage. CONSTITUTION:When 0V is applied to an input terminal IN, and a node B becomes 4.8V pulled down by one stage of the Vf of a diode D1 from voltage source Tl potential 5V, and the terminal IN is changed from 0V to 5V, the potential of the node B is raised by +5V in maximum. The value is adjustable by a cpacitance value at the node A. At this time, since a PMOS M1 is turned OFF when the terminal IN is 0V, ON when 5V, and an NMOS M2 is turned ON when the terminal IN is 0V, OFF when 5V, the node A becomes 0V when the terminal IN is 0V, and becomes the potential pulled down by one stage of the Vf of the diode D2 from the potential of the node B when 5V. Then, since a signal with an amplitude from 0V to 7. 0V extent is outputted to the node A, the drive power of an inverter 13 is increased, and a delay time is reduced.

The distance H between the backup rolls 11 is made unchangeable. Crown control is thus made possible during rolling as well and excellent control performance and the performance under elastic rolling down are obtd.
