Title: Device for sealing electron gun in cathode-ray tube
Inventor: MURAKAMI YOSHIHIRO
IPC: H01J9/00
Filed: 1984-07-02
Abstract: PURPOSE:To enable an electron gun to be concentrically sealed in the neck of a glass bulb by using a chuck having two vertically arranged right-side clicks and one left-side click. CONSTITUTION:A chuck 19 has vertically arranged right-side clicks 20a and 20b which are brought into contact with the outer surface of the neck 1b of a blass bulb. Therefore, even when the clicks 20a and 20a are somewhat worn and torn, the slant of the glass bulb caused is much more smaller than that caused when a conventional device (having a right-side and a left-side click to be brougt into contact with the outer surface) is used because the two right-side clicks and one left-side click of the chuck 19 are pressed upon the outer surface. By using a device for sealing an electron gun in a cathode-ray tube in which the chuck 19 is used, the positional relationship between the glass bulb 1 and the electron gun 2 can be maintained correctly for a considerably long time. Therefore, use of this device enables a cathode-ray tube with very high quality to be manufactured.

Title: Manufacture of semiconductor device
Inventor: KIN CHIYOUKEI
IPC: H01L21/768
Filed: 1993-06-10
Abstract: PURPOSE: To remove defects of voids due to BPSG use for improving the reliability of a semiconductor device by forming a buffer layer between a conductive layer and BPSG film and treating the surface of the conductive layer, when forming the high-conc. P BPSG film for a low-temp. planarizing process. CONSTITUTION: After forming a BPSG film 2 on the top of a semiconductor substrate 1, an impurity-contg. polysilicon 3 and tungsten silicide 4 are deposited and patterned to form bit lines 12. A buffer layer 5 is formed, BPSG film 6 is formed thereon by heat treatment, and BPSG film 7 is formed. Because of the buffer layer 5 between the conductive layer 12 and BPSG film 6, the buffer layer 5 absorbs excessive P from the BPSG film 6 during heat treating and diffuses into the buffer layer 5 to reduce the P concn. This prevents formation of voids due to use of high-concn. BPSG and hence improves the reliability of the semiconductor device.

IPC: B01J8/04
Filed: 1988-06-06
Abstract: PURPOSE:To prevent incomplete combustion and maintain the production of clean exhaust gas for a long term and make it possible to provide a high radiation efficiency by providing substantially in parallel a main catalytic layer and auxiliary catalytic layer downstream of a mixing chamber for fuel and air. CONSTITUTION:The fuel supplied from a fuel supply pipe 1 and the air supplied from a fan 2 are fully pre-mixed in a mixing chamber 3 and the mixture is discharged upwards. It is then ignited by an ignitor 5 at flame openings 4 to start the combustion. The pre-mixed bases out of the mixture chamber 3 reach a main catalytic layer 6 which stands upright but as they mostly develop their combustion on the surfaces on the side of upper flow, they pass via a communicating hole 6a and flow to the side of the down-stream. The combustion exhaust gas further flows upwards and comes in contact with an auxiliary catalytic layer 8, and if in the exhaust gas an unburned portions coexist therewith, they are here totally oxidized and then become clean exhaust gases and discharged via a communicating hole 8a to the upper section on the front. For the catalytic substance a flat plate or cylindrically shaped porous substance holds the catalytic active component with the upper section holding more of it and the lower section less of it.

Abstract: PURPOSE:To prevent the generation of a bent of a dielectric base due to the heat of the sun and the deterioration in the characteristic of the dielectric base by providing a ground conductor to the rear side of the dielectric base having an antenna pattern on its front side and providing a heat sink to the ground conductor. CONSTITUTION:A microstrip line conductor 2 as the antenna pattern is provided to the front side of a rectangular dielectric base 1, the ground conductor 3 is provided to the rear side of the dielectric base 1 to form the microstrip line plane antenna. The heat radiation fin 4 being the heat sink is formed along the peripheral of the dielectric base 1 in one direction. Even if the plane antenna is heated by the sun rays, the temperature rise is suppressed by the presence of the heat radiation fin 4 to prevent the dielectric base 1 from being bent or the characteristic of the base 1 from being deteriorated. As a result, the reduction in the antenna gain is prevented.
