Title: Band pass filter
Inventor: SASAKI KIYOTAKE
IPC: H01P1/163
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a band pass filter that attenuates an electromagnetic wave in the TM 111 mode. SOLUTION: A cylindrical cavity resonator 1 of the band pass filter consists of cylinders 11, 12 whose diameters differ from each other and whose axes are substantially made concentric, which are adhered to each other to form a cavity in the inside. The diameter and the length of the axces of the cylinders 11, 12 are selected so that the cylindrical cavity resonator 1 is resonated in the TE 011 mode. since the diametar of a short-circuit face 11a at the cylindrical cavity resonator 1 differs from that of a short-circuit face 12a, the cylindrical cavity resonator 1 can drastically attenuate an electromagnetic wave in the TM 111 mode and bring the resonance frequency in the TM 111 mode to a frequency at the outside of a pass band of the band pass filter.

Abstract: PURPOSE: To eliminate the internal pressure lowering of an arc extinguishing chamber in the initial stage of opening and sufficiently raise the pressure in the chamber by mounting a check valve for stopping only the gas flow carried from the inner part of the chamber to the outside on an intake hole formed in the chamber. CONSTITUTION: A check valve 23 formed of a tension spring 22, a release valve 20 and a support bar 21 is mounted on an intake hole 2A formed in an arc extinguishing chamber 17. When the outside of the chamber 17 is higher than the internal pressure of the chamber 17, the valve 20 is pushed down to carry the outside air into the chamber 17. When the outside of the chamber 17 is lower than the internal pressure, the valve 20 is pushed up to block the hole 2A.  Namely, the hole 2A extending from the inner part of the chamber 17 to the outside is provided, and the valve 23 for stopping the gas flow only from the inner part of the chamber 17 to the outside is mounted on the hole 2A, whereby the gas is supplied from the outside into the chamber 17 through the hole 2A when the pressure of the chamber 17 is lowered in the initial stage of opening and closing to eliminate the pressure lowering of the chamber 17. On the other hand, since the pressure of the chamber is increased to close the valve 23 when the arc is developed, the pressure of the chamber 17 is further raised.

Abstract: PURPOSE:To manufacture a seamless photosensitive body belt having a flat surface in a short working time by cutting both ends of a cold worked cylindrical member and making it a base material for the photosensitive body belt. CONSTITUTION:For example, Al (alloy), Cu (alloy), etc., are used as metallic material 31. Progressive drawing is made by the general deep drawing to obtain a cylindrical member 32 such as a flanged can and both its ends are cut to obtain an endless belt. This is worked, further, as a base material to obtain a photosensitive belt 30. The peripheral part of the cylindrical member 32 is made 20-80mum in thickness. Moreover, one piece per 2-3sec can be manufactured by this process, for example the working time is exceedingly shorter compared with 30min/piece in electrocasting. Since elastic force is increased and wear resistance is improved by work-hardening based on working stress, the surface is hard to be flamed and dimensional stability is favorable.
