Title: Image forming device
Inventor: NISHIYAMA KAZUE
IPC: G03G21/10
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which can attain reduction of running cost and toner consumption by saving excessive toner sticking to the latent image on a photoreceptor which satisfying the image quality request by a user. SOLUTION: Since the reflection density of the output image is saturated at a point that the development contrast is high, the image density appears identical to a user, regardless of the toner quantity on the image beyond that, and the toner is wasted. In this image forming device, patches are formed on a photosensitive drum with the density from A0H to FFH, measured by a sensor, and a part where the density difference of two adjoining patches becomes below 0.05 is defined as the development contrast. Since the developing bias is constant in this case, the development contrast is controlled by the potential of the maximum image part in the case of forming an electrostatic latent image on the photosensitive drum. This means the development contrast is controlled by the maximum light quantity of a laser.  In the case the density difference becomes 0.06 by B0H and 0.00 by C0H, the C0H is made to be the maximum light quantity as the laser power.

Title: Excitation controller of laser amplifier device
Inventor: KIMURA HIRONOBU
IPC: H01S3/104
Filed: 1987-12-09
Abstract: PURPOSE:To prevent laser power from decreasing, by detecting time difference between a detection signal of an excitation current detecting means and a repetitive pulse signal of an oscillator and by modifying the fluctuating value into a correct delay time and always sending commands to a corresponding variable delay circuit. CONSTITUTION:When in high voltage pulse power sources 2a and 2b of laser amplifiers 1a and 1b delay times until excitation currents are generated in a delay time after trigger signals are received slowly fluctuate, a processor rapidly cancels these fluctuation and sends commands of delay time values to variable delay circuits 6a, 6b of the laser amplifiers 1a, 1b and modifies the delay times. Application time of the high-voltage pulses for excitation accordingly follows the laser beam reaching time, and so drops in output powers of the laser amplifiers 1a, 1b can be avoided to keep the laser beam output power constant.

Filed: 1987-12-09
Abstract: PURPOSE:To prevent the deformation and buckling of a switchboard by forming a circuit breaker chamber containing two DC circuit breakers which are stacked and providing a reinforcing member formed with an arch-shaped frame just under the upper circuit breaker in the chamber. CONSTITUTION:DC circuit breakers 4, 4' are disposed vertically in an enclosed switchboard 1 comprising a box body 1.

Title: End effector for space robot
Inventor: NAKAGAWA JUN
IPC: B25J15/00
Filed: 1988-12-07
Abstract: PURPOSE:To reduce an impact force given to a rod by providing separately a wire rod deciding the position of the rod at the initial catching time and a catching claw initially catching, pulling and holding this rod, in case of catching the rod for catching fitted to the body to be caught under the space environment of micro-movement. CONSTITUTION:The wire rod 9 opening and closing by interlocking with the opening and closing operations of a catching claw 16 has only the initial catching function guiding a catching rod 10 to the center part of an end effector without giving impact force. On the other hand, the catching claw 16 has the pull-in function of the catching rod 10 initially caught and a strong holding function. Thus the impact force given to the catching rod 10 can be reduced at the initial catching time of the body to be catched by separating the functions of the wire rod 9 and catching claw 16 and moreover the pulling and holding forces can be increased. Moreover, due to excessive force being not applied on the wire rod 9 the service life can be prolonged.

Title: Magnetic disk device
Inventor: MATSUKAWA SHIGERU
IPC: G11B20/10
Filed: 1987-12-08
Abstract: PURPOSE:To satisfactorily attain the pulling-out of PLL to synchronizing data of a next sector by providing a selecting means to select and output either of the digital signal or the reference clock signal of an analog reproducing waveform. CONSTITUTION:When a magnetic head 1 crashes into a servo area, the analog reproducing signal of a head amplifier 2 is interrupted and the detecting output signal of an envelope detecting circuit 5 is changed from '1' to '0'. As the result, the input signal of a data separator 8 is switched to a reference clock signal having a frequency equal to the central frequency of the PLL at the same frequency band as the inherent data area and an internal PLL is locked to a central frequency. After a T time lapses, the selecting signal becomes '0', the input of the data separator 8 is switched to the digital signal of the analog reproducing waveform, at the time point, the signal enters a GAP area, and therefore, the oscillation frequency of the VCO of the PLL is not largely removed. Thus, the data separator 8 can satisfactorily pull into the synchronizing data of a next sector.
