Title: Magneto-optical recording method and magneto-optical reproducing method and magneto-optical recording medium
Inventor: OSATO YOICHI
IPC: G11B11/10
Filed: 1993-02-10
Abstract: PURPOSE:To enable overwriting recording by irradiating a first magnetic layer with a magnetization invertable laser beam while repeating on/off or with continuous on according to recording information, thereby recording the information. CONSTITUTION:The magneto-optical recording medium having recording layers consisting of the first magnetic layer 3 which has a compensation temp. between room temp. and Curie temp. and the magnetic layer 4 which has a relatively large coercive force and the low Curie temp. is used. While a recording bias magnetic field is impressed to this medium in a specified direction, the layer 3 is irradiated with the laser beam of the magnetization invertable power by repeating the on/off or with the continuous on according to the recording information. The Curie temp., saturation magnetism and film thickness of the layer 3 and the frequency, recording bias magnetic field direction, size, etc., of the laser to be modulated are so adjusted that the recording pits are not formed with the irradiation at the repeated on/off and the recording pits are formed at the continuous on. The magnetic field for magnetization of the layer 3 is removed and the magnetic field capable of eliminating the boundary magnetic walls is impressed in the same direction as the direction of the recording bias magnetic field at the time of reading out the recorded pits.

Title: Servo system of optical pickup
Inventor: MOMOZAKI EIJI
IPC: G11B7/09
Filed: 1983-02-15
Abstract: PURPOSE:To improve the performance of an optical pickup by moving up and down a laser diode with respect to a disk while rotating said diode by means of the mechanism of a spring, a screw, etc. CONSTITUTION:An SCOOP type pickup shown in a figure (a) contains an optical system including an objective lens, a collimator lens and an LD. In addition, an optical system revolving device 2, a disk 3 and a holding stand 4 are provided to the optical pickup. When the optical system is rotated by the device 2, the optical system moves up and down since a screw is cut to the system. Thus the revolutions and up/down movements can be carried out at a time. While another example shown in a figure (b) includes an electromagnet 1, an optical system containing a magnet at the upper part, a spiral spring 3, a disk 4 and a spring fixing unit 5. The system 2 is rotated by the spring 3 as the system 2 is vibrated up and down by the magnet 1. This system produces both revolutions and up/ down movements at a time.

Title: Charge pump circuit
Inventor: HOSHI TOSHIAKI
IPC: H03K19/094
Filed: 1982-02-17
Abstract: PURPOSE:To obtain a charge pump circuit which operates effectively and securely, by providing two circuits which are driven by mutually out-of-phase current signals to a circuit which generates a prescribed potential difference between the 1st and the 2nd terminals by transferring charges from one terminal to the other. CONSTITUTION:In a period 3, a capacitor C2 is charged by MOSTs M5 and M8 and at this time, the potential at a node E is lowered so that charges are supplied to a substrate from a capacitor C3 charged in the last period. In a period succeeding the period 3, reverse operation is performed in such a way that charges of the capacitor C2 charged in the period 3 are supplied to the substrate and the capacitor C3 is charged by MOSTs M9 and M12. Therefore, when the capacitor C2 or C3 is charged, the other capacitor supplies charges to the substrate and thus charges are supplied to the substrate nealy throughout the periods without reference to the time ratio between the periods 2 and 3. Consequently, the total amount of charge supplied to the substrate is increased and even if a current leaks to the substrate, the substrate potential is held low.

Filed: 1990-02-01
Abstract: PURPOSE:To read in much information even with a narrow bar code area by providing a means which separates the bar code drawn in three primary colors into individual monochromatic light and reads in these light. CONSTITUTION:A light emitting part 6 consisting of a red light emitting part 1, a green light emitting part 2, and a blue light emitting part 3 and a light receiving part 4 are attached to one face of a case 16. When the red light emitting part 1 is lit and a bar code sheet 5 drawn in three primary colors and the case 16 are scanned by relative movement, the red light is reflected by only the base code drawn in red, and the reflected light is made incident on the light receiving part 4 to generate a photovoltaic current, and the current is converted to a signal by a decoding part 8. When the red light emitting part 1 is switched to the green light emitting part 2 by a read control part 7 and they are scanned again, the bar code drawn in green is read in. When the green light emitting part 2 is switched to the blue light emitting part 3 and they are scanned, the bar code drawn in blue is read in. Consequently, the information volume which is three times as large as that a conventional bar code is written.

Abstract: PURPOSE:To obtain a shutter whose precision is stable by providing a pair of same- formed shutter curtains arranged symmetrically with each other in the same axial line direction, a turnable supporting shaft and a pair of springs which are movably fitted on a shaft to energize the curtains in one and the same direction and symmetrically arranging the springs in putting the curtains between them. CONSTITUTION:A pair of same-formed shutter curtains, a 1st curtain 5 and a 2nd curtain 6, are symmetrically arranged and turnably supported to the shaft 7 on the base plate 3. Spring hooks 8 and 9 are rotatively fitted on the both ends of the shaft 7 and detent members 12 and 13 are fixed between pauls on an outer peripheral on the sheet metal 3 so as to prevent the clockwise rotation of the curtain hooks 8 and 9. The springs 10 and 11 energize the 1st curtain 5 and the 2nd curtain 6 counterclockwise, centering around the shaft 7. One end of the spring 10 is engaged with the spring hook 8 and the other is engaged with the pin 5b of the 1st curtain 5 so as to energize the tail part 5a of the 1st curtain counterclockwise. The spring 11 energizes the tail part 6a of the 2nd curtain in the same direction as above. Since the speed characteristics of the 1st curtain and the 2nd curtain can almost completely coincide with each other with such a constitution, the exact precision of exposure can be obtained.

Title: Digital broadcast receiver
Inventor: DATE SATORU
IPC: H04B1/16
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To provide the digital broadcast receiver requiring a longer time by which a digital broadcast program is stored in a recoding medium within its storage capacity.

Title: Thermally fixing apparatus
Inventor: YAMASHITA TADASHI
IPC: G03G15/20
Filed: 1978-03-03
Abstract: PURPOSE: To provide a thermally fixing apparatus, which can effect excellent fixation while preventing jamming or wrinkles, by making equal the circumferential velocities of a fixing roller and a pressure roller during the fixing operation.  
     CONSTITUTION: During the stand-by operation, a fixing roller 14 and a pressure roller 15 are rotating together. Since, however, the number of teeth of a gear 37 is larger than that of a gear 33, the circumferential velocity of the pressure roller 15 is lower than that of the fixing roller 14. Since, however, the coating layers 17 and 20 of the respective rollers have their clearance supplied with silicone oil from a container 23, there arises slip between the layers 17 and 20. When transfer or photosensitive paper enters the clearance between the rollers 14 and 15, the silicone oil is absorbed by the paper so that the frictional force inbetween becomes accordingly high. As a result, the rollers 14 and 15 are allowed to rotate at the same circumferential velocity without any difficulty by interposing an over-running clutch 38. thus, it is possible to prevent jamming and formation of wrinkles.
