Title: Picture quality correction device for electrophotography device
Inventor: KUSUMOTO SHIGEO
IPC: G03G15/00
Filed: 1991-12-19
Abstract: PURPOSE:To reduce the cost by greatly reducing the trouble required to adjust a bias voltage at the time of the manufacture and maintenance inspection. CONSTITUTION:A bias circuit 50 converts the PWM signal outputted from a CPU 47 into a reference voltage which has a level proportional to the duty by a transistor TR1 and an integration circuit 59. A feedback control circuit 60 controls the bias voltage so that a feedback voltage generated by dividing the bias voltage by a specific resistance ratio becomes equal to the reference voltage. The CPU 47 once recognizing the monitor voltage of the bias voltage from a monitor voltage output circuit 57 writes the duty when the bias voltage reaches a specific voltage in a specific address of a RAM 48. When the bias voltage is selected at the time of picture quality correction, the CPU 47 outputs the PWM signal having the duty corresponding to the bias voltage. Consequently, the bias circuit 50 generates the bias voltage corresponding to the PWM signal.

Title: Optical coupling module for optical amplification
Inventor: SATOU HIRAMICHI
IPC: G02F1/35
Filed: 1994-12-26
Abstract: PURPOSE: To prevent such a problem that components increase in size undesirably because of the need to decrease a tilt angle to suppress polarization dependency since the polarization dependency tends to appear largely with the tilt angle of the polarization beam splitter and to eliminate such a defect that an optical axis moves in parallel to a reference optical axis depending upon the tilt angle when a light beam passes through the respective optical components. CONSTITUTION: The size is reduced by using a low polarization dependency multiplexing and demultiplexing prism 9 and bending the light beam of one side at a right angle to increase the separation of the light beam, the polarization dependency is reduced by suppressing the tilt angle between the optical axis and an optical component, and optical axis deviation is corrected by installing optical components in the same shape symmetrically about a mirror plane, and a pentagonal prism or hexagonal prism 11 for optical demultiplexing which is sectioned in a shape formed out of a slanting surface obtained by cutting one side with a plane at 45 deg. to a prism surface after respective rectangular or square prism surfaces are optically polished and a polarization nondependency type optical isolator 3 are arranged on the same optical axis.

Title: Reluctance flat three-phase motor
Inventor: BAN ITSUKI
IPC: H02P25/08
Filed: 1994-12-15
Abstract: PURPOSE: To increase the output torque of a reluctance three-phase motor and decrease the ripple torque of the motor by providing an electric circuit which makes the conducting current of an armature coil quickly fall and rise. CONSTITUTION: A reluctance flat three-phase motor is provided with diodes 49a to 49b-1 and capacitors 47a to 47c . Namely, when the conduction of the motor is discontinued at the end of position detecting signals, the magnetic energy stored in an armature coil 39a is not fed back to a DC power source side by means of the diode 49a-1 , but charges the capacitor 47a to a high voltage through diodes 21b and 21a . Consequently, the magnetic energy quickly disappears and an electric current quickly becomes smaller. When transistors 20a and 20b switch on by means of a position detecting signal and the coil 39a is again energized thereafter, the voltage applied across the coil 39a becomes the sum of the charged voltage of the capacitor 47a and a power supply voltage (voltage across terminals 2a and 2b). Therefore, the current flowing to the coil 39a quickly rises.

Title: Deflection yoke
Inventor: KO YOSHIO
IPC: H01J29/76
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To reduce the loss of an eddy current when magnetic flux resulting from a horizontal deflecting coil is interlinked with a vertical deflecting coil. SOLUTION: A deflection yoke 10 has a core 11 provided with plural slots 12 at least inside, a vertical deflecting coil 13 of predetermined wire diameter wound in the slots 12 of the core 11, a separator 14 provided on the side of the inner diameter of the core 11 on which the vertical deflecting coil 13 is wound and a horizontal deflecting coil 15 of predetermined wire diameter wound on the inside diameter of the separator 14, the wire diameter of the vertical deflecting coil 13 being larger than that of the horizontal deflecting coil 15.  In this structure, as a resistance value for the vertical deflecting coil 13 is smaller than that for the horizontal deflecting coil 15 if having the same wire diameter, vertical deflecting power can be reduced and the loss of an eddy current can be reduced when magnetic flux resulting from the horizontal deflecting coil 15 is interlinked with the vertical deflecting coil 13.

Title: Manufacture of composite property parts
Inventor: KIMURA TOSHIMITSU
IPC: B23K20/00
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To improve the wear resistance of a base body and the joining strength with a green compact with excellent efficiency at a low cost by allowing the green compact of the high alloy powder excellent in wear resistance to adhere to a melting material of the base body at the prescribed temperature, re-heating the adhered member in a short time to generate the plastic deformation, and to compact the green compact. SOLUTION: A green compact consisting of high alloy powder of cold working tool steel excellent in wear resistance is butted to a melting material which is a base body of Fe-based material, and primarily heated at the temperature of not less than 0.5 times the melting point of the high alloy powder to allow both member to adhere. Both members are reheated in a short time without reducing the manufacturing efficiency, e.g. within approximately 100 second, and the plastic deformation is generated in the base body through the forging to obtain the shape close to a final parts. The high alloy green compact is compacted through the plastic deformation so as to be uniformly dense, and the joining strength with the base body is improved.  Then, as necessary, the high alloy green compact is sintered and diffusion-bonded while generating the plastic deformation in the base body in the temperature range of >=0.7 times the melting point of the high alloy powder.

Abstract: PURPOSE:To improve the above device so as to obtain the electrocardiographic waveforms enhanced in S/N and to allow the execution of the resonance signal data sampling sequence exactly synchronized with the palpitation of the heart by effectively eliminating noises due to a gradient magnetic field, etc. CONSTITUTION:An electrode 52 for grounding is stuck to the body surface skin of nearly the central part of the body of a person 11 to be inspected. Noise 62 of an in-phase flowing in electrodes 53, 54 for signal detection is removed by a differential amplifier 56. On the other hand, a coil 55 for noise detection has a looped conductor spanned between the electrodes 53 and 54 for signal detection and noise 63 appears in reverse polarity at both ends thereof. This noise is amplified by a differential amplifier 57. The outputs of the two differential amplifiers 56, 57 are inputted to a differential amplifier 58 and, therefore, the noise 63 remaining in the output of the differential amplifier 56 is cancelled. The signal (g) of the electrocardiographic waveform 61 from which the noise 62 of the in-phase and the noise 63 of the anti-phase are both removed is sent from the differential amplifier 58 to a timing generating circuit. The pulse sequence exactly synchronized with the palpitation of the hearth is formed.

Filed: 1990-11-30
Abstract: PURPOSE:To reduce a switching loss in the case when a discharge lamp is demounted before lighting by connecting a starting resistance connected to the other electrode of the discharge lamp to the base of a switching transistor. CONSTITUTION:Electric current is passed by the output of a DC power supply circuit 2, through the electrodes Fa and Fb of a discharge lamp FL1, a preheating condenser C2, and an AC coupling condenser C3 in either one of the first winding T1a or the second winding T1b when a switching transistor Q1 is turned on and energy stored in one side winding to which electric current has been fed, is reversed and discharged into the other winding of either the first winding or the second winging via a diode D1 oriented in its normal direction when the switching transistor Q1 is turned off, so that the discharge lamp FL1 is lit by a resonant voltage generated by a series resonance. After the lighting, when the fluorescent lamp FL1 is removed or the electrodes of the discharge lamp FL1 are short-circuited, a protective transistor Q2 is turned on to protect the switching transistor by holding it in its off state. Consequently the switching loss can be reduced.

Filed: 1990-11-30
Abstract: PURPOSE:To perform normal navigation processing by stopping renewing and memorizing an azimuth variation when a vehicle runs at a preset speed or slower, in accordance with a speed detection signal. CONSTITUTION:A vehicle stops running during turning a corner Cl, e.g. during a (5) sampling time representing A4-A8 vehicle runs, when a current azimuth variation  d detected for that period is zero without being renewed and memorized in preset data regions M1-M8, as shown in Fig. A. Then, when the vehicle runs along a road following the position A4 at a preset speed or faster again, the detected current azimuth variation  d is renewed and memorized in the preset data regions M1-M8 in sequence as shot in Fig. B. Accordingly, no matter whether the vehicle is stopped on the way to turn the comer 1 or not, just the same data is written in the preset data regions M1-M8, to allow accurate judgement whether the vehicle turns the corner 1 or not and normal navigation processing.
