Title: Spindle motor mechanism for disc device
Inventor: SOTOZONO MEGUMI
IPC: G11B19/20
Filed: 1985-10-18
Abstract: PURPOSE:To reduce the torque ripple of a motor by mounting the magnetic poles of a motor while being deviated with each other so as to avoid the deficiency of a start torque. CONSTITUTION:The magnetic poles of a motor 2 only are mounted while being deviated by 90 deg. (the deviation is changed depending on the number of magnetic poles of a rotor). In said spindle motor mechanism, a torque exerted to the rotary shaft is a combined torque (b) between the torque A of a motor 1 and the torque B of the motor 2. A 4-pole rotor and 3-phase full wave drive motor is used for each motor. Thus, the minimum torque is increased by nearly 1.2 times in comparison with a conventional motor torque and the amplitude of the torque ripple is nearly 1/4, and the mean torque is improved at the same time. Thus the deficient start torque is avoided, the start time is shortened, the efficiency is increased, noise and the fluctuation of rotation are reduced.

Title: Method for detecting short circuit between terminals of linear solenoid of electronically controlled automatic transmission
Inventor: SUGIURA MASAYUKI
IPC: F16H61/02
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To surely detect a short circuit of terminals even when a battery voltage changes, by comparing a judgment duty ratio with a set duty ratio and judging it a short circuit of terminals when the set duty ratio is smaller than the judgment duty ratio. SOLUTION: Unless a short circuit is generated between terminals, a duty ratio set through feedback control is not in a variable range of a duty ratio at the time of a short circuit between terminals even when a voltage changes. Nothing this point, a judgment duty ratio is set on the basis of a set duty ratio (Dmin-s -Dmax-s ) which becomes a target value when a short circuit occurs between terminals. If the set duty ratio to be the target value (Dmin-s -Dmax-s ) through feedback control becomes smaller than the judgment duty ratio, it is judged as the short circuit of terminals. Accordingly, the short circuit of terminals can be detected even when the voltage changes.

Title: Image recorder
Inventor: SHIRAISHI ATSUSHI
IPC: H04N1/04
Filed: 1987-09-16
Abstract: PURPOSE:To facilitate control with simple construction by controlling a driving device and coinciding a scanning line in a spiral shape to be scanned with the LED of three colors. CONSTITUTION:Simultaneously with the main scanning revolution (an arrow A) of a revolving drum 20, an exposure head 22 is successively moved in a sub-scanning direction (an arrow B) at a constant speed. Then, an image is formed by the scanning line of the spiral shape to a photosensitive material coiled to the drum 20. Here, at the moving time, an image data signal is immediately outputted from an image data output circuit to an LED158C. However, the image data are phase-delayed for a part corresponding to the different of positions between an LED158B and the 158C by a phase delay circuit and outputted to the LED158B. The image data signal is phase-delayed for the part corresponding to the difference of the positions between an LED158A and the 158C by the phase delay circuit and outputted to the LED158A. Thus, the dislocation of the signal by the difference of the fitting position of the LED is removed and the exposure of the three colors is executed to the same position as the photosensitive material of the drum 20. Then, a color image is formed.

Title: Method and device for setting time at reloading
Inventor: OSAKI TOMOKO
IPC: G06F13/00
Filed: 1988-09-19
Abstract: PURPOSE:To automatically and continuously set the reloading time points by reading out periodically the reference time which is set by a host device or updated by a lower rank device as the latest time and comparing this latest time with the immediately preceding time. CONSTITUTION:The reference time which is set by a host device 2 or stored in a 1st storing part 3 via a timer updating part 5 of a lower rank device 1 is read out periodically by a reading means as the latest time. This latest time is compared with the immediately preceding time stored in a 2nd storing part 4 via a comparison instruction means 8. In case the latest time is not coincident with the time of the part 4 and updated for a fixed time, the latest time is stored in the part 4 as the immediately preceding time. In case the coincidence or discordance is obtained between those two times with the time value less than the fixed time, the immediately preceding time of the part 4 is updated by a timer updating part 6. Then the unupdated latest time is stored in the part 4 as the fault occurring time. A loading detecting means 9 detects a reloading action and the means 8 recognizes that the latest time read out periodically by the means 7 is updated. Thus the means 8 writes the updated immediately preceding time of the part 4 into the part 3 and defines it as the reference time. In such a constitution, the time can be automatically set without deteriorating the continuity of the time.

Title: Hologram exposing method
Inventor: FUKUI TAKUOMI
IPC: G03H1/04
Filed: 1990-09-04
Abstract: PURPOSE:To correct image distortion, generated at the time of reproduction of a hologram of a curved surface, by exposure in the state of a flat plate hologram photosensitive material by arranging a cylindrical lens in the optical path of one of laser light beams which are body light and reference light. CONSTITUTION:Laser light 2 from a laser device 1 is made incident on objective lenses 5 and 5' through mirrors 3 and 3' and a beam splitter 4 to become diverged light beams 6 and 6'. The light 6' irradiates the hologram photosensitive material 8 as it is. The cylindrical lens 7 is newly installed between the objectives and photosensitive material 8 so as to deform the wave front of the diffused light 6. The lens 7 deforms the light 6 as shown by 7', the light becomes elliptic on the photosensitive material 8, and the ellipticity of the transmitted light 7' can freely be selected by varying the distance between the lens 7 and lens 5. When a hologram exposed elliptically to the photosensitive material 8 is reproduced in the curved state, circular reproduction light cancels the exposed state even if distorted owing to the curvature and operates equivalently to irradiate a plane hologram with circular reproduction light.

IPC: H02M7/145
Filed: 1990-09-03
Abstract: PURPOSE:To control a subject at a high speed and with high accuracy by increasing the deviation between the controlled variable of the controlled system and the set value with an amplifier means, converting the analog signal of the increased deviation into a digital signal, and obtaining a manipulated variable based on the digital signal. CONSTITUTION:A digital signal showing the set value, i.e., a current command of an electromagnet 30 is inputted to a D/A converter 16 from a computer 10. Thus the digital signal is converted into an analog signal by the converter 16 and supplied to a comparator 18. When the output signal of the comparator 18 is amplified by an amplifier 22, an error, i.e., the deviation between a controlled variable and the set value is increased by an amount equal to the amplification degree of the amplifier 22. Therefore the control accuracy is improved when the increased level of the error is converted into a digital signal from an analog signal. Thus a controlled system is controlled at a high speed and with high accuracy.
