Title: Oscillation circuit
Inventor: UMEDA HIROYUKI
IPC: H03K3/0231
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To provide an oscillation circuit in which the oscillation frequency is not changed even when power source voltage is changed and in which a device for stabilizing the power source voltage is not required. SOLUTION: A constant current generating part 1 generates a constant current I2 in proportion to an optional voltage VIN. A capacitor C is charged by the constant current I2 which is generated by the part 1. A comparator 21 compares the charge voltage of the capacitor C with a reference voltage VIN and generates an 'H' level discharge signal when the voltage exceeds the reference voltage VIN. An NMOS transistor N1 is turned on and also the charge of the capacitor C is discharged by the discharge signal. When the discharge is completed, the capacitor C is re-charged. The discharge signal of the comparator 21 is taken out from an output terminal 3 as an oscillation output.

Title: Electrophotographic sensitive body
Inventor: MIZUTA YASUSHI
IPC: G03G5/05
Filed: 1988-11-29
Abstract: PURPOSE:To improve the surface smoothness and wear resistance of a charge generating layer by applying a charge generating coating liquid contg. a charge generating material, polyvinyl acetal and specific metal alkoxide on a charge transfer layer to form the charge generating layer. CONSTITUTION:The charge generating layer 3 to be provided on the outside surface of the charge transfer layer 2 is formed by applying the charge generating coating liquid prepd. by dispersing the charge generating material and the metal alkoxide expressed by the formula M(OR)n (where M denotes a metal element, such as Ti, Zr or Al; R denotes 1 to 6C alkyl group; n denotes an integer) into a binder resin, such as polyvinyl acetal, and a solvent on the outside surface of the charge transfer layer 2 and drying the coating. The metal alkoxide is, therefore, hydrolyzed and the polyvinyl acetal and the metal alkoxide make condensation reaction at the time of drying of the charge generating coating liquid, by which the hydroxyl groups in the polyvinyl acetal are decreased. The disturbance of the charge generating layer 3 is prevented in this way and the wear resistance of a surface protective layer 4 and the photosensitivity of the photosensitive body are improved.

Title: Acousto-optical filter
Inventor: TANAKA FUMIO
IPC: G02F1/11
Filed: 1990-11-06
Abstract: PURPOSE:To simultaneously utilize an ordinary ray and an extraordinary ray which are incident at the same angle, whose wave length are the same for an incident ray in a natural polarizing condition by installing a tellurium dioxide crystal and a transducer and setting an optical incident angle and the wave front of a transversal ultrasonic wave in a specified bearing referring to a crystal axis and diffracting the ordinary ray and the extraordinary ray by transversal ultrasonic waves having the same frequencies as both the rays. CONSTITUTION:The surface of an optical incidence of a tellurium oxide crystal 1 inclines by Q1 from an axis (110). A ray of light almost vertically strikes upon that surface, and when diffraction does not occur, the ray of light becomes a transmitted ray of light 1o and goes out. A transducer 2 is adhered to the surface which inclines by alpha from an axis (001), and an electric signal from a high frequency oscillator 3 is changed into an ultrasonic signal by a transducer 2 and is propagated through the inside of an crystal 1. Then, the ultrasonic wave whose wave front tilt angle alpha is transmitted much inclined from the axis (101) because the crystal 1 is anisotropic; and an incident ray is selectively diffracted corresponding to the frequency of ultrasonic wave and an ordinary ray goes out as the filter light I1 of an extraordinary ray whose polarized light is turned by 90 deg., and the extraordinary ray goes out as the filter light I2 of the ordinary ray, respectively. It is thereby possible to use both the rays at the same time for an incident ray whose natural polarizing condition is general, too.

Filed: 1993-12-01
Abstract: PURPOSE: To improve the data updating speed of a disk storage device. CONSTITUTION: A data block is recognized by a host by means of f fixed logical address and stored at a physical position selected by a controller 10. The block written in by the host is stored in buffers 12a to 12n in the controller 10 until it amounts to a selected number (n). After then a track is selected from each disk storage device and the block in the buffers is written into the track so as to parallelly writing each track to all the disk devices during one rotation of a disk. The selected number (n) is (the number of blocks in each track)×(the number of the disk storage devices). The controller 10 manages an indirect map 18 deciding a physical position on the disk from the fixed logical address of the block. The indirect map 18 is nonvolatile in order to prevent the loosing of data due to a fault. An allocation map 16 shows which physical block is under usage.  Whenever the number of null tracks becomes lower than a threshold value, the controller 10 shifts and exchanges the block to make a new null track.
