Title: Ac discharge tube
Inventor: EGAWA AKIRA
IPC: H01S3/038
Filed: 1986-10-15
Abstract: PURPOSE:To prevent a high electric field from being formed thereby to eliminate the danger of dielectric breakdown between a pair or more of electrodes by providing the electrodes on the outer surface of a pipe of a dielectric and covering by molding the electrode ends along the longitudinal direction of the electrodes with an insulator. CONSTITUTION:A pair of electrodes 2, 2' are formed on the outer surface of a pipe of a dielectric 1, and molding films 3, 3' of predetermined insulating material are formed to cover the electrode ends E along the longitudinal direction of the electrodes 2, 2'. A silicone polymer insulator or fluorine polymer insulator (e.g., Teflon polymer) is adapted as an insulating material for covering it by molding. That is, the insulators become rubberlike insulators to cover the ends E to fill the gap densely to eliminate a void, thereby obviating the room of generating a corona discharge at all. Further, the dielectric strength is large, a thermal stability is obtained, and organic gas to reduce the breakdown strength in gas is not exhausted.

Title: Orthogonal converting circuit, modulator using the same, demodulator and orthogonal angle correcting method
Inventor: OTSUKA TOSHIMASA
IPC: H04B14/00
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To perform a correction into phase difference so that two systems can have a mutually exact orthogonal angle. SOLUTION: The correction is performed so that the output signal of a system I can be exactly orthogonal to the output signal of a system Q. The phase difference in the output signal of the system Q to the orthogonal angle when the output signal of the system I is defined as a reference is detected while using a phase difference detector 7. On the basis of the detected phase difference, a control means 15 shifts the phase of the output signal of the system Q while using a direct digital synthesizer(DDS) 5b so that the output signal of the system Q can be exactly orthogonal.

Abstract: PURPOSE:To obtain a uniform film by preventing the wrinkles of the film on a roll, by forming a groove functioning as the escape passage of involved air to a backing roll. CONSTITUTION:For example, when a thin film 1 with a thickness of 1.5mum and a width of 500mm comprising polyethyleneterephthalate is sent to a backing roll 10, air is also involved in the backing roll 10 with the running of the film 1. In this case, for example, by providing 70 grooves each having a width of 0.5mm and a depth of 0.4mm to the backing roll 10 at the pitch equal to a coat margin part, air involved between the roll 10 and the film 1 can be escaped and the generation of wrinkles is prevented.

Abstract: PROBLEM TO BE SOLVED: To enable highly accurate measurement regardless of any change in the step of a diffraction grating by selecting the best interference signal from among a plurality of interference signals different in the cycle of changes in the diffraction efficiency to determine an amount of positional deviation. SOLUTION: Positive primary diffraction light with a frequency f1 from a diffraction grating 7 and negative primary diffraction light with the frequency f2 are polarized by mirrors 27, 25 and 11 to be admitted into a polarization beam splitter PBS12. Then, the direction of polarization is adjusted by a polarizing plate 15 and a beat signal M1 is detected by a sensor 16. On the other hand, the negative primary diffraction light with the frequency f1 and the positive primary diffraction light with the frequency f2 are respectively polarized by mirrors 28, 26 and 13 and admitted into the PBS14 to detect a beat signal M2 by a sensor 18. The beat signals M1 and M2 are compared in the intensity of the signals, S/N, phase stability and the like by a superiority judging means 19 to determine the superiority of the signals and a superiority signal is outputted to a phase difference meter 20.  The cycle of changes in the intensity of the diffraction light varies with respect to changes in the step of the diffraction light. Therefore, the cycle of changes in the intensity of the diffraction light of the beat signals M1 and M2 also differs thereby preventing the intensity of both the signals from being minimized.

Title: Image forming device
Inventor: ATSUMI TOMOYUKI
IPC: G03G15/00
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To enable copying documents to be ejected on an identical tray by continuing the pages thereof in their order even when the number of copying documents becomes over the loading capacity of the tray, by taking out the sheets placed on the first tray in a lump and ejecting them to the second tray by inverting the front and the back surfaces thereof. SOLUTION: When it is judged by a control part that the loading amount of a paper accumulation part 11b exceeds an allowable amount before the copying action of one part of images is not finished, the copying action is stopped. Besides, an instruction is outputted so that the copying action is executed from the final image out of the read images which are not copied. When the copying action is finished, the copying documents loaded at the accumulation part 11b are ejected on the tray 41 in a bundle through a path 66 without being stapled as they are.  Since the bundle of the documents loaded at the accumulation part 11b is superposed on the bundle of the documents placed on the tray 41 by inverting the front and the back surfaces, the documents loaded at the accumulation part 11b are superposed on the documents arranged on the tray 41 from the final page by making the copied surface face upward so that the documents of the accumulation part 11b are made to face upward from the final page. Thus, the document bundle arranged from the head page is completed on the tray 41.

Title: Measurement for electronic beam pulse width
Inventor: OZAKI KAZUYUKI
IPC: H01L21/66
Filed: 1985-10-31
Abstract: PURPOSE:To calculate a pulse width accurately, by a method wherein an electron beam (EB) pulse is converted into an electrical signal to be amplified and integrated to calculate an EB pulse width from an saturated value of the DC voltage signal obtained. CONSTITUTION:An EB pulse 10 directed through an EB pulse gate is projected to a microchannel plate (MCP) 11 in a sample chamber. An output current of the MCP 11 is picked up through an isolation amplifier 12, and after being amplified with an amplification circuit 13, the output current is integrated with an integrator 15 and taken out as DC voltage with a sampling and hold circuit 16. When the EB pulse irradiation frequency is 0, the output voltage is 0. But as the irradiation frequency is increased, the output voltage is insulated to a value in proportion to the peak value of the output voltage of the amplifier 13. The saturated voltage is compared with the measured value of the EB pulse with the known pulse width to calculate an unknown pulse width. Thus, the pulse width of the EB pulse such a very short as about less than 100ps can be measured with high accuracy without being affected by jitter.
