Title: Disk eccentricity compensating device
Inventor: KONO KEIICHI
IPC: G11B21/10
Filed: 1989-10-31
Abstract: PURPOSE:To always output the correcting signal of an exact phase and amplitude by comparing an eccentricity correcting signal from a correcting amount generator with a position signal from a position signal demodulator and correcting an eccentricity correcting amount based on the result of this comparison. CONSTITUTION:A voice coil motor 3 moves a head 2. A timing identifier 4 identifies a phase signal in a circumferential direction from a servo surface 1. A position signal demodulator 5 demodulates a signal showing the position of the head 2 in a radial direction. A correcting amount generator 6 generates the correcting signal in this positions signal synchronously with the timing signal of the identifier 4. A compensator 7 compensates the position signal adding the correcting amount from this generator 6. Thus, the eccentricity correcting signal from the generator 6 is compared with the position signal form the demodulator 5 by a comparing means 8. Based on the comparing signal of this means 8, an arithmetic circuit 9 corrects the eccentricity correcting amount to be generated by the generator 6.

Title: Charge removal apparatus
Inventor: IZUMI KENKICHI
IPC: H05F3/04
Filed: 1988-11-10
Abstract: PURPOSE:To make the structure of the title apparatus small and remove charge certainly without being influenced by the charged amount of the charged body. CONSTITUTION:A plurality by conductive fibers 2 in order are fixed in a conductive body 3 in their one ends and the conductive body 3 is covered with an insulator to give an electrode part 1 of a charge removal apparatus. When high voltage of alternating current is applied to the electrode part 1 by a alternating current high voltage generating means 4, electric discharge in low current is generated between the charged body and the fibers and the charge of the charged body is certainly removed regardless of the charged amount. Since the electric flow rate of the high voltage is small, the size of the charge removal apparatus is made small.

Title: Portable terminal equipment
Inventor: KUZE KOICHI
IPC: G10K9/122
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To increase the sound pressure level of a ring back tone produced from a sounding body without increasing an electric input applied to the sounding body by adjusting the phase of sound from one side of a diaphragm through a pipe to the outside in the frequency of a call termination alarm tone and equalizing that phase with a sound from the other side of the diaphragm. SOLUTION: When an incoming call is received, an electric signal for reporting call incoming is inputted to a sounding body 3. Based on that electric signal, the sounding body 3 vibrates a diaphragm 4, and the sounds of phases different at 180 deg. are radiated from its inside face 4A and outside face 4B. The sound radiated from the inside face 4A is passed through a hole 3B and radiated from an opening 5 to the outside like an arrow (c). Besides, the sound radiated from the outside face 4B is radiated from an opening 7 at the other end of a pipe 9 to the outside. As a result, since the sounds radiated as shown by arrows (c) and (d) outside a casing 1 are synthesized in-phase, the sound pressure level is increased. In this case, the sound pressure level of sound from the opening 7 can be increased rather than that of sound from the opening 5 by a resonance phenomenon.

Title: Color thermal printing method
Inventor: NISHIMURA TOMOYOSHI
IPC: B41J2/36
Filed: 1994-11-18
Abstract: PURPOSE: To prevent the generation of a black or white streak caused by load fluctuations. CONSTITUTION: An yellow thermal head, a magenta thermal head and a cyan thermal head are arranged along the passing region of color thermal recording paper and a full-color image is recorded on color thermal recording paper by one movement. During the recording of the yellow thermal head, the pressure contact of the magenta thermal head and the supply of a current are started. Contrarily, during the recording of the magenta thermal head, the stop of the supply of a current to the yellow thermal head and the retreat thereof are performed. By this behavior of the thermal heads, the feed load of color thermal recording paper is changed. Since the strain quantity of a feed system is changed by this load fluctuation, the feed speed of the color thermal recording paper is changed temporarily and a line during recording becomes a black or white streak.  The heat energy generated in the thermal head is corrected with respect to this line to prevent the generation of a streak.

Abstract: PURPOSE: To simply provide the prescribed clearance between the lapped surfaces of members to be welded by the laser beam. CONSTITUTION: The solvent into which the bead-shaped spacers 1 having the diameter equivalent to the dimension of the clearance suitable to the welding conditions are mixed is applied on the lapped surfaces of the part to be welded where a plurality of members 4, 5 to be welded are lapped on each other.

Filed: 1994-11-18
Abstract: PURPOSE:To perfectly prevent the adhesion of dirt at low cost by feeding a photosensitive material through a carrying path in a device by selecting double- row transfer and inter-row transfer. CONSTITUTION:A method in which one-row transfer is performed against two- row transfer is selectively executed. Namely, the photosensitive material PC printed and exposed in an exposure part A successively reaches a carrying and sorting device 10, and a moving path 13 receives the material PC at a position where the center of the width thereof agrees with the central position of an introducing part. While the material PC is fed to a downstream side in the moving path 13, the moving path 13 is moved to the left side. Thereafter, the photosensitive material PC1 fed to the carrying path 20A advances slowly, while the moving path 13 receives the next photosensitive material PC2 and moves to the carrying path 20B side on the right side. Furthermore the materials PC and PC are fed to a next development processing part at low speed, while the moving path 13 is restored to a home position. Then, the material PC is ejected from the parallel carrying path 20 and passes in the center on the roller of the developing part C, so that cleaning is performed.

Filed: 1991-10-07
Abstract: PURPOSE:To control scanning speed of laser and improve the molding accuracy in an apparatus for molding a three-dimensional solid by applying laser to a photosetting fluid substance. CONSTITUTION:A self-standing tank 70 is provided inside of a base 20, and a photosetting fluid substance 100 is filled in the tank 70. A stable 80 in the tank is controlled in the direction of a Z axis. A head 50 controlled along the X-axis and Y-axis is equipped with a laser irradiation device 60, and laser beams from a laser oscillator 210 are applied into the tank. When electrification is conducted to the laser oscillator, the electrification time is measured by a timer and then delivered to an arithmetic processing unit 250 together with the ambient temperature of the laser oscillator 210. The arithmetic processing unit acts to predict the laser output from these data so as to determine the scanning speed. The actual laser output is measured by means of an optical sensor 400 for correcting the predicted output, thus the accuracy is improved.

Abstract: PROBLEM TO BE SOLVED: To smoothly drive zooming even when a low output small motor is used. SOLUTION: A clearance is taken between the outside diameter of a motor 41 and the inside diameter of a motor supporting frame 40 and they are positioned by three motor positioning screws 49 to the motor supporting frame 40 and lightly fixed. Since the motor supporting frame 40 and the motor 41 have no eccentricity and the motor 41 moves in front and behind in that condition, the motor 41 is fixed by soft resin 50 on the outer periphery around the rear end so as not to be moved in front and behind. Since the soft resin 50 is soft resin, the motor supporting frame 40 and the motor 41 are relatively movable to the extent of the clearance.
