Title: Automatic paper feed device
Inventor: YOKOYAMA RIYUUZABUROU
IPC: B65H3/06
Filed: 1981-12-03
Abstract: PURPOSE:To make it possible to carry out manual insertion of paper feed with simple operation in an automatic paper feed device for transferring stacked sheets one by one with the use of the difference between frictional forces of a separating plate and a separating roll with respect to the sheet, by making the separating roll swingable. CONSTITUTION:In case that an original is fed exceptionally by means of manual insertion of paper feed, a solenoid 10 is at first energized for pulling up a link 8 by a plunger 11 overcoming a spring 13, and therefore, a swingable bridge 5 rotates around a drive shaft 4 as the center. Due to this rotation, a separating roll 6 carried by the forward end of the swingable bridge 6 moves downward below an original carrier table 2, as the result, a gap 16 is formed between a separating plate 15 and the separating roll 6 so that the original to be manually inserted is easily carried away. Thus, it may be sufficient for shifting the operation from automatic paper feed to manual insertion of paper feed to turn over a selector switch for energizing the solenoid 10.

Title: Second harmonic generating device and method
Inventor: MIYAKE KAZUYUKI
IPC: H01S3/109
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To obtain a strongly modulated second harmonic by a method, wherein the second harmonic is generated only when the laser ray wavelength of an LD is in the phase-matching allowable wavelength range of a wavelength conversion means, and the second harmonic is reduced to almost zero in output, when the laser ray wavelength of an LD is out of the phase-matching allowable wavelength range. SOLUTION: A domain inversion element has a phase-matching allowable wavelength width to phase-match only with the laser rays of certain wavelengths out of laser rays of variable wavelength range emitted from an LD. The domain inversion element having a phase-matching allowable wavelength width of λn to λ1 is used. In this case, only the laser rays of wavelengths λn to λ1 out of laser rays of variable wavelength range λ2 to λ1 and in a phase-matching allowable wavelength width are wavelength- converted to a second harmonic and outputted. On the other hand, laser rays of wavelengths less than λ2 to λ1 are not converted into wavelength, and a second harmonic intensity-modulated with the same frequency with laser rays emitted form the LD is generated.  Through this setup, a second harmonic generating device which is very small in size, simple in structure, easily operated, and high in performance is capable of generating an intensity-modulated second harmonic.

Title: Method for confirming operation of electric field sensor
Inventor: MURAMATSU RYOJI
IPC: G01R15/24
Filed: 1994-07-26
Abstract: PURPOSE:To confirm the operation of a photo detector by comparing a modulation signal obtained by modulating a light source with an output signal which is converted after passing the modulated light through the photo detector. CONSTITUTION:In a state where no electric field is applied to an electric field sensor head 1, a light source 2 is directly modulated by a modulation signal generator 7 and an output signal from an amplifier 4 connected to a photo detector 3 is detected. The detection signal is compared with the modulation signal of the light source 2 which does not pass through the photo detector 3 and the amplifier 4 by a comparator 8, thus checking whether the photo detector 3 and the amplifier 4 connected to the photo detector 3 operate properly or not. Then, light with a certain intensity is outputted from the light source 2 and an electric field is applied to the electric field sensor head 1 to measure electric field. In this manner, the operation of the photo detector 3 or the amplifier 4 connected to the photo detector 3 can be confirmed before measuring electric field, thus improving the reliability in the measurement data by an electric field sensor.
