Abstract: PURPOSE:To improve light transmission to a deflector and utilization efficiency by a low-cost optical system by constituting a beam shaping optical system from a light source to a deflector by using a collimator lens, a beam expander, and a beam compressor. CONSTITUTION:A laser diode 100 emits four laser beams, which are converted into parallel light beams by an aspherical collimator lens 101; and an elliptic stop 102 restricts the luminous flux and the main light beams of the respective laser beams are made to cross one another in the center of the stop 102. Then enlargement conversion is performed by the main-scanning-directional beam expander consisting of a concave cylindrical lens 103 which has refracting power in a main scanning direction and a spherical lens 104. Then the light is made incident on the reflecting surface of the rotary polygon mirror 1 through a concave cylindrical lens group 105 which does not have refracting power in the main scanning direction. In a subscanning direction, on the other hand, the beam compressor consisting of a lens 104 and a concave cylindrical lens group 105 reduces the light beam to specific beam width and the light is converged on the reflecting surface at a small angle of convergence. In this constitution, the laser output energy is utilized efficiently and a compact scanner is obtained.

Title: Motor control device
Inventor: KUSANO AKIHISA
IPC: H02P6/16
Filed: 1993-03-10
Abstract: PURPOSE:To stably hold the frequency characteristic of a servo system by a method wherein, when the number of revolutions of a motor is changed by a number-of-revolutions changeover means, a reference-voltage control means changes a reference voltage and the operating point of a phase control signal is moved to a point where a quantization error is small. CONSTITUTION:The velocity control output AFC of a PLL control IC 10 is in inverse proportion to a target velocity omega0, a control-system gain is changed due to a change in the number of revolutions, and the control stability is worsened. Then, resistances 16, 17, 18 which decide the output AFC are connected in parallel, analog switches 31, 32 are turned on/off according to the number of revolutions, and only the gain of the output AFC is changed. When the number of revolutions is changed and a motor current is changed, the output voltage of the AFC is changed, and there is a possibility that the output voltage is passed through a point where the quantization error of a D/A converter is increased. However, when transistors 33, 34 are turned on/off by signals SIG 5, SIG 6 and a Vref is changed so as to match a motor current Imu, one output voltage of an APC can be moved to a desired point.
