Title: Focus servo system
Inventor: RUDOUIN SESUKOBUSUKII
IPC: G11B7/12
Filed: 1993-09-02
Abstract: PURPOSE: To accurately obtain the position which can draw by detecting the optimum focus position which can draw focus servo based on a focus error signal and an information signal when the information signal is temporally lost. CONSTITUTION: A reproduction signal is impressed to a laser 3 via a line 3a, generates a read beam 4 and turns on a spindle servo device 50. The device 50 accelerates a spindle motor up to an appropriate rotating speed, impresses a carriage servo device 55 and moves a carriage as the beam 4 positions the first place of information which is stored in a video disk recording body 5. Then, a lens focus servo device 36 automatically moves a lens 17 on surface of the disk 5, and the lens 17 can pass through the optimum focus. At this time, the device 36 combines an FM signal with a difference focus error signal and detects the optimum focus position that can draw. When an information signal takes longer than a prescribed time, a slope signal is as a driving signal instead of a focus error signal and focus servo is drawn.

Title: Protecting circuit for communication equipment
Inventor: KOBAYASHI SHUNJI
IPC: H02H9/04
Filed: 1987-09-01
Abstract: PURPOSE:To suppress electrostatic capacity between a line and the ground, by constituting a protection circuit with two sets of single phase rectifying bridge circuits and overvoltage protection elements. CONSTITUTION:Upon occurrence of input lightning surge voltage between a line side terminal OP-T and the ground G, surge current flows through a diode D1a and Zener diodes 2D1e, D1d to the ground G. Since output voltages from D1a, D1b are low, almost all lightning surge voltage is clamped by the output voltage from ZD1e. Surge voltage in negative direction also flows through G, D1b, ZD1e, D1c to the line side terminal OP-T. Upon occurrence of input lightning surge voltage between a line side terminal OP-R and the ground G, second single-phase rectifying bridge circuit functions similarly. Since electrostatic capacitance is low and no resistor is included in such arrangement, a protection circuit for high speed digital signal can be realized.

Title: Turret mooring ship
Inventor: KITAGAWA KIICHI
IPC: B63H9/06
Filed: 1985-10-04
Abstract: PURPOSE:To make possible to actively control a turret mooring ship, by planting an airfoil type sail on, for example, a deck or the like, in the stern section (or bow section) of a ship, and by attaching a swingable auxiliary sail to the airfoil sail or by making the airfoil sail rotatable so that the airfoil area thereof is made to be variable. CONSTITUTION:An airfoil sail 2 is arranged rotatably about a mast, and is planted on a deck in the stern section (or bow section) of a hull 1. Further, the lift of the sail 2 is changed with respect to a wind stream having a certain angle with respect to the hull 1 by actively controlling the hull 1. Accordingly upon active control of the hull, the angle of the sail may be controlled to obtain an optimum yawing moment with the use of a lift characteristic curve which is obtained from data of tides, waves and air streams which vary every moment. Further, it is possible to cope with a condition of external force which is different from a design condition. With this arrangement, the coefficient CMZ of horizontal angular moment about a turret 50 as a rotating center axis, may be made to be large, thereby it is possible to enhance the effect of weathercock.

Abstract: PURPOSE:To obtain a good head touch and to allow the stable execution of recording and reproducing by providing a recessed part on the slider gliding surfaces of the magnetic heads and decreasing the air bearing pressure generated between magnetic cores and sliders. CONSTITUTION:The recessed parts 25, 35 are provided on the sections of the other magnetic heads facing the magnetic cores 24, 34 of one of the magnetic heads 20, 30.

Consequently, the deformed layer of a magnetic recording medium 40 is decreased and the spacing between the magnetic gap surface and the magnetic recording medium 40 is diminished. The recorded and reproduced outputs are increased. Thus, the magnetic head with which the good head touch with the magnetic recording medium is obtained and the sufficient reproduced output is assured is obtd..

Title: Epoxy resin composition for photocoupler
Inventor: SHIMAWAKI HIROSHI
IPC: C08L63/00
Filed: 1985-10-04
Abstract: PURPOSE:To obtain an epoxy resin composition for photocouplers having improved reliability and optical transmission at a low cost, by adding an epoxy resin to molten silica powder in a specific ratio as an inner resin. CONSTITUTION:Epoxy resin and a hardening agent are added in a ratio of 30-70 parts by weight to 100pts.wt of molten silica powder. If the epoxy resin and the hardening agent are contained in a ratio lower than 30pts.wt., light is scattered more by the molten silica powder and consequently the optical transmission is decreased. If they are contained in a ratio higher than 70pts.wt., on the contrary, the inner resin constituted thereby would be peeled off from the outer resin and the reliability is deteriorated. Further, molten silica powder having spherical particles with an average diameter of 20-50mum is preferably used for improving the optical transmission and the uniformity in formation.

Filed: 1990-08-22
Abstract: PURPOSE:To measure the size of a tumor in the body of a morbid person by linear graphy by spotting a heavy metal on a plastic board transmitting radiation, electron beams and visual lights at equal intervals and in cross form, with respect to the wide surface of the plastic board. CONSTITUTION:In a radiotherapy device having a radioactive ray and electron beam radiating facility, a plastic board 1 is selected in a thickness optimizing influences of transmissivity, attenuation factor of radioactive ray and flatness of exposure distribution. A heavy metal 2 prevents the transmission of radioactive ray, electron beams and visible lights. A dial plate 3 is placed on the lower end of the radiation part 4 of the radiotherapy device. A radioactive cone 6 emitted from a radiation source 5 transmits the dial plate 3 and the tumor part 8 of a morbid person 7, and is radiated to a cassette 9 receiving a X-ray film. Thus, the heavy metal 2 spotted on the plastic board 1 at equal intervals in cross form is photographed on the X-ray film of a linear graphy. The dimensional relation between the photographed heavy metal 2 and the tumor part 8 is measured, whereby the size of the tumor part 8 in the body of the morbid person 7 can be known.

Abstract: PURPOSE: To provide a method for producing a single crystal, capable of preventing the dissociation of an element high in the vapor pressure from the surface of the crystal, capable of forming the solid-liquid boundary shape in the downward deposited shape, and capable of preventing the polycrystallization of raw materials.
