Title: Timer device
Inventor: MORI SHINTAROU
IPC: H03K5/13
Filed: 1983-12-28
Abstract: PURPOSE:To prevent a timer from malfunctioning owing to an error input signal due to a noise and variation in source voltage by applying a timer output to a gate circuit which gates an input signal through a delay circuit. CONSTITUTION:When the input signal is inputted to a terminal 1, it is inputted to a waveform shaping circuit 3 through an amplifier 2 and the gate circuit 11 in the on state and a discharging circuit 4 is operated to discharge a capacitor 7. When this discharging advances until the voltage across the capacitor 7 drops below a reference voltage 8, the output of a comparator 9 is inverted and a time limit output appears at an output terminal 10. This timer time limit output is delayed by a specific time through the delay circuit and supplied to the gate circuit 11 to turn off the gate. Consequently, the output of the amplifier 2 is not transmitted to the circuit 3 and the discharging circuit does not operate, so the capacitor 7 is charged through a resistance 5 and when its voltage exceeds the reference voltage 8, the output of the comparator 9 is inverted again to turn on the gate, so that the timer device is held in readiness for input application.

Title: Light source device
Inventor: KISHI HIROTOSHI
IPC: H01S5/024
Filed: 1983-12-29
Abstract: PURPOSE:To obtain a simply constructed, small type, low price light source device of stable wave length and output of light by making a construction of directly supporting a semiconductor laser element with a mount which has PTC characteristics. CONSTITUTION:A mount 12 which closely supports a semiconductor laser 11 of light source is made of a substance which has great positive resistance temperature coefficient, i.e., PTC characteristics. For this reason, if a current flows in the mount 12, it works as an ordinary exothermic resistance since the mount 12 is low resistance at lower temperature than switching temperature. If the temperature of the mount 12 rises to the switching temperature region where the resistance rapidly increases, the current in the mount 12 becomes very small and the rise of temperature stops whereby the temperature of the oscillator region of the semiconductor laser 11 is balanced and maintained at nearly constant. Consequently, the wave length of laser light is maintained at nearly constant and the output of light becomes stable.

Title: Semiconductor laser treatment device
Inventor: YANO NOBUYUKI
IPC: A61F9/00
Filed: 1988-10-04
Abstract: PURPOSE:To make it possible to synthesize light beams from a plurality of semiconductor laser sources and to effectively focus the same onto a laser conductor by providing a plurality of semiconductor laser sources, and by incorporating a focusing member for the laser conductor, integrally with a member for synthesizing light beams from the plurality of semiconductor laser sources. CONSTITUTION:A semiconductor laser beam has been linearly polarized. Since a polarizing splitter surface 4 cannot synthesize laser beams 1, 2 if their polarizing planes have equal angles, the polarizing plane of only one of the light beams 1, 2 is rotated by an angle of 90deg. with the use of a 1/2 wavelength plate so as to effectively synthesize these two light beams 1, 2. The light beams emitting from laser sources are focused onto the incident end face of bundle fibers 6 through anamorphic lenses 5a, 5b, 5c. The light beams may be effectively focused to a fine fiber by arranging the fibers in one row at the image forming position of a laser emitting section. Since the focusing member for the light conductor may be incorporated integrally with the light beam synthesizing member, it is possible to simplify the optic system and to make the device compact.

Title: Ac motor drive inverter control method
Inventor: HAYASHI HIROAKI
IPC: H02P27/04
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To control the abnormality of a motor current due to the discontinuous change of a deviation angle δ between a d-axis value and a q-axis value when an AC motor operated by a VVVF inverter for analysing it into the d-axis value and the q-axis value to perform vector control is reversed. SOLUTION: An electrical angle holding circuit 31 holds an electrical angle θobtained at the time of the inversion of an electric motor as it is to give it to a vector rotation device 23 as a d-q axis computing electrical angle θ1 and however, if a comparator 32 detects θ1 =θ, the holding state is released. Therefore, it can be avoided that a d-axis voltage detection value Vd and a q-axis voltage detection value Vq computed by the vector rotation device 23 become an abnormal value.  Further, a pattern generating circuit 33 avoids that a d-axis adjustment computing value Vd1 and a q-axis adjustment computing value Vq1 outputted from an adjustment device 13 become an abnormal value by weakening the adjustment device gains K1 , K2 of the adjustment device 13, and the current jump or the generation of an abnormal sound of an induction motor 4 driven by a VVVF inverter 3 is reduced.

The conveyance unit 3 is rotatably provided, and a positioning member 29 is excited in the direction into contact with the side face of the image forming device main body 1 by a torsion coil spring 28. Since the positioning member 29 is positioned in contact with the side face near the sheet receiving port 13, the positional relation between the conveyance unit 3 and the sheet receiving port 13 is not drifted largely even if the relative position between the image forming device main body 1 and the conveyance unit 3 is somewhat drifted. The sheets P can be smoothly delivered to the sheet receiving port 13 from the conveyance unit 3.
