Title: Disk player
Inventor: FUJIWARA SHUNJI
IPC: G11B33/02
Filed: 1989-09-14
Abstract: PURPOSE:To prevent the possibility that a disk jumps even when a disk cover is opened while the disk is rotated by providing a damper spring which gives prescribed resistance to a cover opening spring which is moved together with the disk cover when it is shifted to an opening state in the direction that the energizing force is made weak. CONSTITUTION:A disk loading part is provided with the damper spring 9 which gives the resistance to the cover opening spring 3 so as to make the energizing force thereof weak and which temporarily decelerates the opening speed of the disk cover in the case that the disk cover is shifted to the opening state after the driving of a turntable is stopped at the neighboring of the cover opening spring 3 by the operation of a switching means. Besides, the supporting arm 9b of the damper spring 9 is fixed to a chassis 2 and the loading arm 9a of the damper spring 9 is made to contact with the bent part 3b of the supporting arm 3a of the cover opening spring 3 by weak load. Thus, even in the case that the disk cover is opened when the disk is driven to be rotated for reproducing or the like, the disk is prevented from jumping.

Title: Facsimile system
Inventor: KOBAYASHI SHIGEYUKI
IPC: H04N1/00
Filed: 1988-09-27
Abstract: PURPOSE:To shorten the line monopoly time by sending a character data added with a control code and a compressed picture data to a line in time division. CONSTITUTION:A man-machine interface control section 2 displays a character entered from a keyboard 3 onto a display device 4. After the generated original is divided into a character data and a picture data by a main control section 1, the result is stored on a floppy disk in an FD drive 6. The main control section 1 reads out the stored character data to add a control code thereto and compresses the readout picture data and sends both the data to a line via a FAX control section 8 in time division. The main control section 1 at the receiver side expands the character code according to the attribute of the control code and synthesizes the character data and the picture data. Thus, the line monopoly time is shortened in this way.

Abstract: PURPOSE:To easily take a rack gear out of a processing tank by providing a conveyance rack with the rack gear, engaging a pinion with the rack gear, and providing an operation part which rotates this pinion to move up and down the rack gear and thus moves up and down the conveyance rack. CONSTITUTION:The pinion 46 is rotated by operating the operation part to move up the rack gear 44 toward a processing tank 14, thereby moving up the processing rack 32.

Filed: 1987-09-24
Abstract: PURPOSE: To provide a device which is constituted so that color irregularity and illuminance irregularity are reduced and picture quality is high by making red, green and blue light beams incident on a liquid crystal light valve by giving prescribed inclination to the main optical axes with respect to the normal line of the surface of the liquid crystal light valve. CONSTITUTION: The red, the green and the blue light beams are made incident on the liquid crystal light valve 6 by inclining the main optical axes by 5 deg.-10 deg. with respect to the normal line of the surface of the valve 6. The liquid crystal light valve for a red and a green light beams and the liquid crystal light valve for a blue and a green light beams 6 are arranged at a symmetric position with respect to the respective wavelength selecting and synthesizing surfaces of a dichroic prism 7. Thus, since the light beams are made incident in the direction of the distinct vision of liquid crystal, brightness depending on the angle of the distinct vision is not remarkably changed even when the incident angles of the light beams are slightly deviated.  Besides, the distribution irregularity of every red, green and blue light beams on a screen is reduced and the nonuniformity of illuminance is also reduced. Then, a bright screen as a whole is obtained.

IPC: G01N1/02
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a dusting characteristic evaluating method which is reliable in measurement accuracy, is simple in operation procedure, and uses inexpensive measuring equipment with no special constraint on measurement locations. SOLUTION: After pressing the self-adhesive surface 3 of a self-adhesive tape 2 against the surface of each object to be evaluated with a predetermined pressure, the lightness index L* and chromaticness indices a* and b* of a dusting substances 5 in L*, a*, and b* color systems adhered to the pressed section 4 of the self-adhesive surface 3 are measured. The dusting characteristics of each object to be evaluated are evaluated by the difference between those indices and the indices L*, a*, and b* of a self-adhesive tape to which no dusting substances are adhered.  Therefore, as indices L*, a*, and b* take different values in each object to be evaluated according to the amount of the dusting substances 5 adhered to the self-adhesive surface 3, it is possible to evaluate the amount of the dusting substances 5 in each object to be evaluated by comparing the indices L*, a*, and b* of each object to be evaluated with one another.

Abstract: PURPOSE: To compensate the deterioration of oxygen sensor outputs by detecting the bias of the oxygen sensor resulting from deterioration, and controlling the amount of fuel delivered to an engine according to the detected bias of the oxygen sensor. CONSTITUTION: A detection signal of a heated exhaust gas oxygen sensor 30 for detecting the oxygen content of the exhaust gas of an engine 11 is input to a fuel controller 100, and a total switching time(t) which is the total of a first switching time t1 for switching from a lean air-fuel composition to a rich air-fuel composition and a second switching time t2 for switching from the rich air-fuel composition to the lean air-fuel composition is measured with an oxygen sensor monitor 125 and checked to see whether or not the total switching time(t) is within a predetermined range. If the total switching time(t) is within the predetermined range, the difference between the first and second switching times t1, t2 is checked to see whether or not it is within a second predetermined range.  If the difference is within the second predetermined range, the oxygen sensor 30 is determined to be operating effectively. If the difference is outside of the second predetermined range, a compensation value is calculated as a function of the difference in switching times to vary air-fuel ratio.

When the substance approaches the faucet, the solenoids 11, 12 are opened at the distance L1 and when it separates therefrom, the solenoids are closed at the distance L2. In this case, L1 is larger than L2.  The direction of the faucet 7 is, detected by a faucet-directional detector 17 and when the faucet 7 is turned to a position deviated from the sink 3, the solenoids 11, 12 are closed. Accordingly, it prevents water discharge on a cooking table and the responsiveness of discharge of water and cut-off of water is improved.

IPC: H03H9/145
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To realize a small capacitance by digging down portions existing between electrode fingers from a portion where the electrode fingers are provided. SOLUTION: A portion 10b between electrode fingers 12 is dug down just for t2 in respect to a portion 10b where the electrode fingers 12 are formed. The t2 greater than '0' and formed by a technique such as reactive ion etching(RIE). By digging down the portion 10b between these electrode fingers 12, reducing action is generated in the value of an effective dielectric constant related to electrostatic coupling of the mutually adjacent electrode fingers 12. Namely, among the electric lines of force generated from an arbitrary electrode finger 12, the line passed through a piezoelectric substrate 10 is passes through the area of dielectric constant = 1, namely, in the air and the effective dielectric constant related to electrostatic coupling between the electrode fingers 12 is lowered.  As a result, even without extremely reducing the number of electrode fingers or opening length, electrostatic coupling between two terminals can be made into small value.
