Title: Method for driving display device
Inventor: TAKEDA YOSHIYA
IPC: G09G3/36
Filed: 1991-10-09
Abstract: PURPOSE:To reduce the driving electric power and to improve the display picture quality and driving reliability by mutually superposing and/or canceling variation in the potential of a pixel electrode and an image signal voltage, and applying the voltage to a display material. CONSTITUTION:When a switching element is a TFT 3, potential variation CgdVg with an image signal which induces potential variation Vg of a scanning signal through a gate-drain capacitance Cgd is generated in a negative direction. Then positive and negative asymmetrical modulated signal widths Ve (+) and Ve (-) which are inverted in application polarity, field by field, are supplied through a storage capacitance Cs to generate potential variation CsVs (+) in the negative direction and CsVe (-) in the positive direction at an image electrode, so that they are superposed in the potential variation CgdVg/C1. When those potential variation values are larger than the threshold voltage of liquid crystal, part of a liquid crystal driving voltage is supplied from the capacitance coupling potential, so the output amplitude of an image signal driver is reduced and the driving electric power is reduced.

IPC: A47K10/48
Filed: 1994-09-30
Abstract: PURPOSE: To make an eye or a face hard to receive the irradiation with ultraviolet rays even when a user allows his head to approach an irradiation region of ultraviolet rays or looks into the irradiation region in a blast drying device performing the blowing-off of hot air from an opening part and the irradiation with ultraviolet rays. CONSTITUTION: Ultraviolet rays are emitted from a sterilizing lamp 8 to be emitted from the opening part of a sterilizing lamp cover 7. The ultraviolet scattering preventing member 9 attached to the opening part of the sterilizing lamp cover 7 guides the ultraviolet rays emitted from the sterilizing lamp 8 in the direction parallel to the arranging surface of a duct 15 and having the same angle of inclination as the duct 15 to prevent them from scattering in a direction other than this direction. Or, the ultraviolet scattering preventing member 9 prescribes the emitting direction of ultraviolet rays to the direction inclined on the back surface side of this device with respect to the axial line of the duct 15. By this constitution, ultraviolet rays are prevented from scattering in the front direction where a user is positioned.  Further, a tray surrounding the front space of a hot air blowoff port 12 from left and right side surfaces, a bottom surface and a back surface is attached.

Title: Output buffer delay adjusting circuit
Inventor: IKETANI MITSUTO
IPC: H03K19/0175
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To unnecessitate delay adjusting work on a design stage in the case of distributing simultaneous operation signals to be inputted to respective output buffers by inserting delay elements. SOLUTION: Delay circuits 2 to 4 are a delay element group connecting delay elements, each delay circuit has two input terminals for a normal signal and delay adjustment to delay an output signal to be outputted to each of output bullers 5 to 7 and these two terminals are used by switching. A frequency division circuit 1 generates a delay adjusting signal and inputs the signal to respective delay circuits 2 to 4. A phase comparion and delay circuit control circuit 8 compares the delay quantity of respective output signals Sa, Sb, Sc outputted from respective delay circuits 2 to 4 after inputting the signal from the circuit 1 to the circuits 2 to 4 and generates control signals Ca, Cb, Cc for determining the delay quantity of respective delay circuits 2 to 4.  Since the delay adjustment of the output bullers 5 to 7 is automatically executed at the time of turning on a power supply before inputting normal signal at a product stage, delay adjustment by the insertion of delay elements at a design stage is made unnecessary.

Abstract: PURPOSE: To obtain an optical disk capable of preventing the use of a copy version using a DRAW type optical disk by providing a CAV area in the optical disk of a CLV system and making a recording position in the CAV area a value corresponding to TOC information. CONSTITUTION: The CAV area is provided in a data recording area of a CD- ROM optical disk 4 of the CLV system, and at least each recording position in the CAV area is made to be an intrinsic value to a title corresponding to intrinsic TOC information to such a title stored in a read-in area.

Then, a track number or a header address in the CAV area is calculated to detect a linear velocity to discriminate the authenticity. Consequently, when the disk is to be copied, equipment and skilled labor, commensurate with the copy work are required, and a working amt. is remarkably increased, so that inexpensive production is infeasible, and hence appearance of an illegal copy version can be suppressed.
