Title: Disk cartridge
Inventor: FUJITA MINORU
IPC: G11B23/03
Filed: 1987-09-18
Abstract: PURPOSE:To prevent the inner plane of a cartridge case from being scraped due to the sliding of a spring and to prevent an error from being generated due to scraped chips at the time of recording and reproduction by interposing and arranging an abrasion preventing member superior in lubricity between the spring mounted on a shutter and the inner plane of the cartridge case. CONSTITUTION:The abrasion preventing member 31 superior in the lubricity is interposed and arranged between the spring 25 mounted on the shutter and the inner plane of the cartridge case 1. The abrasion preventing member 31 is constituted of a cylinder part 31A being housed in the coil part 25A of the coil spring 25 and the supporting part 31B of flange shape which supports the coil part 25A. And the spring 25 is deformed, and the sliding of the spring 25 for the inner plane of the case 1 generated due to deformation is performed directly via the abrasion preventing member 31. Thereby, it is possible to prevent the inner plane of the cartridge case 1 from being scraped due to the sliding of the spring 25, and to prevent reliability for the recording and the reproduction from being lowered due to the attachment of generated abrasion powder on a disk.

Title: Optical phase synchronization light source and optical frequency synchronization light source
Inventor: IMAYADO WATARU
IPC: H04B10/572
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To realize highly reliable optical phase synchronization and optical frequency synchronization by controlling a resonator length of optical frequency variable laser light source, a refractive index of a laser resonator and the temperature of a laser resonator based on a low frequency element of an error signal. SOLUTION: An optical multiplexer 41 combines controlled light and reference signal light. When a signal showing optical frequency difference of both lights is output from a balanced receiver 42, a phase detection means 6 inputs an output signal of a balanced receiver 42 and an output signal of an offset frequency setting means 5 for detecting phase error of both lights. That is, only a low frequency element of an error signal which is fed back to an optical frequency variable laser light source 1 is separated and a resonator length of the optical frequency variable laser light source 1 is controlled. Thereby, loop gain of a DC proximate element can be increased and an optical phase synchronization holding width can be increased to GHz or more without greatly affecting output light intensity of the optical frequency variable laser light source 1.

Title: Surface light source element and liquid crystal display device
Inventor: FUKUOKA HIROMI
IPC: G02F1/1335
Filed: 1994-09-28
Abstract: PURPOSE: To obtain a high-luminance edge light system surface light source element by coating a nearly half outer peripheral area of a long light source on an opposite side to a light transmission plate with a light reflection layer and disposing a reflection member having a light reflection surface whose cross- sectional shape is curved in the longitudinal direction of the long light source. CONSTITUTION: The long cylindrical light source 13 is disposed along one end face of the minor axis of the light transmission plate 10, and a reflector 14 being a reflection member where silver is vapor-deposited is provided on the outer periphery of the light source 13. Furthermore, the nearly half area positioned on the opposite side to the plate 10 on the outer periphery of the light source 13 is coated with the light reflection layer 15. The layer 15 consists of a film sheet where silver is vapor-deposited, and a fluorescent lamp is coated with the layer 15 by adhesive agent. Since the layer 15 is just near to the light source 13 and its arranged position is closer to the plate 10, the reflected light on the layer 15 is most easily made incident on the end face of the plate 10 in a state where the repetitive reflection after that is little.  Thus, much light is introduced to the plate 10, so that high luminance is obtained.

Title: Continuous gas analyzer
Inventor: MIKI HIDEYUKI
IPC: G01N27/04
Filed: 1986-09-29
Abstract: PURPOSE:To detect an accurate delay time on the basis of an average value and standard deviation during a definite time before the gas introduced into an analyser is changed over from specimen gas to zero gas. CONSTITUTION:When it is a definite time T, during analysis by an analyzer 12, before a control means 20 changes over a change-over solenoid valve 6 from the side of a specimen gas line 2a to the side of a zero gas line 14a, a signal is sent to an average value calculation means 22 and a standard deviation calculation means 24. The means 22, 24 calculate the average value X and standard deviation sigma of the indication of the analyzer 12 up to time To when the solenoid valve 6 is changed over. A k.sigma calculation part 28 calculates the product k.sigma of the constant (k) from a constant setting part 26 and the standard deviation sigma. At the time To, a delay time detection means 30 detects time when the indication 18 of the analyser 12 changes by k.sigma from the average value X and the time from the time To to the detection time is detected as a delay time Td.

Title: Heating cooker
Inventor: IWABUCHI YASUSHI
IPC: F24C7/06
Filed: 1988-09-17
Abstract: PURPOSE:To improve a thermal efficiency and prevent a deformation of a door as well as its discoloration by a method wherein a flat heater is press fitted to a concave part formed in the ceiling of a heating chamber, and a clearance between the front end of the flat heater and the inner surface of the door is made larger than a clearance between the rear inner surface of the heating chamber and the rear end of the flat heater. CONSTITUTION:A flat heater 6 is press contacted to a concave part 1a formed at a ceiling part of a heating chamber. Therefore, even if a size accuracy at a fixing position of a press containing part between the ceiling surface of the heating chamber and the flat heater 6, a clearance of the press contacting part can be easily restricted to a small value and a thermal efficiency can be improved. In addition, a clearance A between the front end the flat heater 6 and an inner surface of a door 18 is set higher than a clearance B between a rear inner surface of the heating chamber 1 and the rear end of the flat heater 6. Therefore, even if the ceiling of the heating chamber near the plane-like heater 6 is heated up to about 500 deg.C so as to perform a grill cooking, a temperature of a contacting part between the inner surface of the door and the front surface of the heating chamber may not be increased up to such a temperature to cause a deformation or discoloration of the door to be generated.

IPC: B41J2/01
Filed: 1992-08-07
Abstract: PURPOSE:To prevent the unnecessary mixing of ink and a transparent solvent, thereby obtain stable printing characteristic, by providing, at a mixing part of the two kinds of liquid, a sealing substance introducing means for introducing a sealing substance for separating the liquids. CONSTITUTION:A piezoelectric vibrator 5 is shifted thereby to shift a vibrating plate 4. As a result, a transparent solvent 3 in a liquid chamber 1 is pressured, whereby a sealing substance 11 in a mixing part 6 is discharged outside via a nozzle 7. Then, an ink quantifying part 10 is controlled to supply an ink 8 into the mixing part 6 through an ink exit 9a, so that a desired density of ink is obtained. A halftone liquid having the density modulated as above is thus prepared. A predetermined voltage is impressed between electrodes 5a of the piezoelectric vibrator 5 to shift the vibrator 5 thereby to add pressure to the transparent solvent 3 in the liquid chamber 1. The halftone liquid formed in the mixing part 6 is discharged because of the above pressure via the nozzle 7 and adhered onto a printing paper. Accordingly, it becomes possible to form dots having the modulated density onto the printing paper.

IPC: G21F9/28
Filed: 1994-09-28
Abstract: PURPOSE: To decontaminate a large radioactive metal waste as a whole, reduce decontamination agent amount and increase decontamination effect by inserting a supporting matter with the same shape in a decontamination tank of similar shape to the outline of the radioactive metal waste. CONSTITUTION: Decontamination agent 11 is contacted to all surface of a decontamination object of rectangular tube 2 in fuel rack 3 which is metal waste contained in a decontamination tank 1 to chemically decontaminate.
