Title: Optical information processor
Inventor: SUGIYAMA TOSHIO
IPC: G02B26/10
Filed: 1980-10-15
Abstract: PURPOSE:To make the device small-size and light-weight and facilitate the production and reduce the power consumption, by forming a reflective mirror on one face of an electrostrictive element to oscillate a light flux. CONSTITUTION:The light flux emitted from a light source 1 such as a semiconductor laser passes through a lens 2, a polarizing prism 3, and a 1/4-wavelength plate 4 and is reflected by a mirror 7 and is focused onto a disc 10 as a point 12 by a condenser lens 8. The mirror 7 is provided on one face of a vibrator 5, and the vibrator 5 is oscillated minutely in a constant frequency by the output of an oscillator 15. The reflection light is reflected by the polarizing prism 3 and is incident to a photodetector 18. The output is taken out from a terminal 30 and not only is processed as a reproducing signal but also passes through a band pass filter 13 and has the phase detected in a phase detector 14 by the output from the oscillator 15, and thus, the focus of a lens system 8 is controlled through a control circuit 16 and an actuator 9. Thus, the device is small-size and light-wheight and is easy to produce and the power consumption is reduced.

Title: Method of preventing glow discharge for electric dust collector
Inventor: TAKATO KAZUAKI
IPC: H01T19/00
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a method of preventing glow discharge for an electric dust collector in which glow discharge can be prevented to maintain dust collecting performance without tripping the device. SOLUTION: When sparks happen frequently to lower charging voltage and the charging voltage is continuously less than set sampling voltage 'a' for set sampling time 'b', that glow discharge is generated is determined, charging is stopped. After prescribed time 'c' (for example, 2 sec) has passed from the stoppage of charging and inner ions of an electric dust collector have been initialized or approximately initialized, charging is resumed to increase charging voltage to voltage (for example, 24 kV) corresponding to an on-recharging electric current 'e' (for example, 100 mA). After with this charging voltage being held, recharging time 'f' (for example, 50 sec) has passed from the resumption of charging, the charging voltage is increased to rated voltage 60 kV to perform normal operation.  After the inner ions in the electric dust collector are thus initialized or approximately initialized, the charging voltage is increased to the set rated voltage while controlled, thereby preventing glow discharge to maintain dust collecting performance of the electric dust collector.

Title: Tank for oil-filled electrical machine
Inventor: ITOU TATSUO
IPC: H01F27/02
Filed: 1979-11-05
Abstract: PURPOSE:To remarkably reduce the maximum generating stress generating by the pressure applied to the tank by bending both end sections of the longitudinal section of the side plate of a tank substance for formation wherein the longitudinal section works as lengthwise reinforcement wall sections serving as the side walls of a gas chamber. CONSTITUTION:Both end sections of a side plate 10 composing of the longitudinal section of an oval tank are bent by 90 deg. in a unidirection to compose lengthwise reinforcement sections 11. The reinfocement sections 11 also work as the side walls of a gas chamber 13 comparted by a reinforcement plate 12 installed at the outside of the side plate 10. Bending sections 14 of the side plate 10 contact with the end sections of the semicircular side plate 15 of the tank. Both of them are united each other to form the tank substance. In this way, when pressure is applied to the tank at the time of vacuum extraction or the like, generating stress at the coupling sections with the reinforcement sections 11 provided on the side plate 10 and the side plate 15 will remarkably be reduced.
