Title: Inverter device
Inventor: FUJITANI YOICHI
IPC: H02M7/48
Filed: 1986-09-18
Abstract: PURPOSE:To reduce the waveform distortion of the output voltage of an inverter easily by outputting a control signal from an error amplifier within the range of the angle of the generation of the waveform distortion when the waveform distortion is generated and controlling a reference sine wave. CONSTITUTION:When a waveform distortion is generated in output voltage, the waveform distortion is detected by a momentary-voltage detector 28. Since the momentary-voltage detector 28 outputs absolute voltage equivalent to the full wave rectification of output voltage, a waveform corresponding to output voltage is transmitted over a second error amplifier 13. Since a reference sine wave is inputted to the second error amplifier 13, an output corresponding to the difference of the reference sine wave and a detecting waveform corresponding to output voltage is obtained. The output is outputted as a control signal, thus controlling the reference sine wave. Accordingly, the output voltage of the inverter is controlled instantaneously, thus acquiring output voltage having a little waveform distortion.

Title: Mobile communication system
Inventor: MATSUMOTO SHINJI
IPC: H04B7/24
Filed: 1990-08-22
Abstract: PURPOSE:To attain discovery of a faulty mobile station and disconnection of the station at a point of time of registration processing by starting the registration of a mobile station through the reception of a registration request signal in a contention channel. CONSTITUTION:When a mobile station 2 is already registered tentatively, a registration enable signal is sent through a polling channel 11 and the state transits to a registration signal reception standby state. When the registration signal is received in this state, the main registration processing of the mobile station 2 is implemented. When timeout takes place in the registration signal reception standby state, number of times of retransmission of the registration enable signal for the mobile station 2 is checked. As a result, when the number of times of retransmission exceeds number of times of retrial, the tentative registration of the mobile station 2 is made obsolete and the state is transited to the polling timing standby state. Since the registration is started through the reception of the registration request signal through the contention channel, not only the registration of the faulty mobile station whose system has a fault is avoided, but also the required time till the registration of the mobile station is finished is reduced.

Filed: 1990-08-22
Abstract: PURPOSE:To reduce the frequency of recomposition of a sleeve and a tip and to improve the productivity with continuous operation by fitting a ceramic to at least one side of sliding face of the sleeve and the tip. CONSTITUTION:By using the ceramic sintered body having excellent corrosion resistance to molten metal to the sliding parts of sleeve and tip for die casing machine, the increase of abrasion rate caused by corrosion abrasion can be prevented, and by making material having solid lubrication to at least one side in these and high strength and high hardness ceramic sintered body to the other side, coefficient of abrasion can be reduced. This is caused by solid lubrication (self-lubrication) and since burning galling, etc., by this action can be prevented, the consumption of lubricating oil can be made to <=1/3 compared with the ordinary case. Further, since the high strength and high hardness ceramic sintered body is scarcely worn, and smooth sliding face is kept for semi-permanent, the abrasion rate of solid lubricating material can be made to <=1/10 compared with the ordinary combination of metals.

Title: Semiconductor laser device
Inventor: WAKANA SHINICHI
IPC: H01S5/00
Filed: 1986-09-20
Abstract: PURPOSE:To simplify the assembling and regulation of a semiconductor laser and to maintain the accuracy after the assembling for a long period by providing reflectors on the reflecting surfaces of the reflecting end faces of the outside of a single mode waveguide region to form a resonator. CONSTITUTION:A light irradiated from a laser 7 at a reflecting surface 5 is passed through a single mode waveguide region 3 of length l of 1/4 wavelength plate into the laser 7. The light irradiated first from the reflecting surface 5 from the semiconductor laser 7 is reciprocated to 1/4 wavelength plate having an optical axis inclined at 45 deg. with respect to the TE polarizing surface. Thus, the polarizing surface is clearly rotated at 90 deg., and converted to a TM polarized light perpendicular to the TE polarization. On the contrary, the light irradiated from the TM polarization is converted to the TE polarization. In case of oscillation, the irradiated light of the laser 7 is limited in longitudinal and lateral directions according to single mode waveguide regions 3, 4, to be enclosed therein and not extended to the periphery. Accordingly, the reflected lights from the surfaces 5, 6 can be substantially returned into the laser 7.

Abstract: PROBLEM TO BE SOLVED: To prevent a belt from twisting and wrinkling by providing a meandering detecting device for detecting the amount of meandering of the belt, a meandering correction roller for shifting the traveling direction of the belt, and a device for displacing the meandering correction roller which changes the conditions that the meandering correction roller is put into contact with the belt. SOLUTION: When a transfer belt 5 begins to meander to the left and is detected by a meandering detector 27, a CPU rotates the motor 29b of a roller displacing device 29 according to the output value of the meandering detector 27 to lower the roller bearing 28c of the correction rollers 28a, 28b. When the upper correction roller 28a is lowered to put into contact with the transfer belt 5, the transfer belt 5 is shifted to the right to correct the meandering. Since the pressed contact amount of the correction rollers 28a, 28b is controlled proportionally to the amount of meandering detected by the meandering detector 27, the larger the amount of meandering is, the more greatly the intermediate transfer belt 5 is shifted to quickly correct the meandering.
