Title: Vacuum heat insulation material
Inventor: SATO HIROYOSHI
IPC: F16L59/06
Filed: 1993-11-22
Abstract: PURPOSE:To keep heat insulation performance as a whole body of a heat insulation material even when vacuum is leaked by a flaw such as a pinhole by enclosing a filler inside an enclosing material to form a closed body in a low vacuum condition, and separating the closed body into plural closed chambers. CONSTITUTION:For an enclosing body, that having favorable gas barrier property is used for holding vacuum inside. Filler 3 may be filled inside the enclosing material 1, but in the case of forming a vacuum condition, the filler 3 in it is sucked with gas, so it is desirable to put the filler 3 which is once packaged in an interior material 2 in the enclosing material 1. For the interior material 2, gas-permeable one having a smaller aperture size than the size of the filler 3 is applicable, such as woven fabrics and nonwoven fabrics. A vacuum closed body is formed small by being separated for the purpose of keeping heat insulation performance as the whole body of a heat insulation material even when a defective occurs by a flaw such as a pinhole in one closed body to break vacuum in a chamber.

Title: Pulverized coal combustion apparatus
Inventor: YAMADA KAZUJI
IPC: F23C99/00
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To stop swirling of pulverized coal flow and form an igniting swirling flow by turbulent flow without deteriorating thick and thin fuel concentration separation effect by arranging flame stabilizing blocks above an inner cylinder of a pulverized coal nozzle and a flame stabilizer protruding from a distal end periphery of an outer cylinder and broadening toward a downstream side. SOLUTION: Flame stabilizing blocks 8 constitute a plurality of straight passage extending in an axial direction and an annular passage, which does not break a pulverized coal passage, between an outer cylinder 15 of a pulverized coal nozzle 6 and the flame stabilizing blocks and are arranged above an oil primary air nozzle 12 which corresponds to an inner cylinder. Pulverized coal fed as shown in an arrow (A) is made to swirl in an upstream side of the pulverized coal nozzle 6 to effect thick and thin fuel concentration separation by centrifugal force, and when reaching a top end portion, the pulverized coal flow is turned into a straight flow with maintaining thick and thin fuel concentration separated state by the flame stabilizing blocks 8 to form a thick pulverized coal portion 9 and a thin pulverized coal portion 10, both of which are charged into an after flow.  The thick pulverized coal portion 9 achieves flame stabilization in a whole periphery because being oriented to a flame stabilizer 3 side, and on the other hand, the thin pulverized coal portion 10 forms an igniting swirl by the flame stabilizing blocks 8 so that igniting performance toward a center side of the pulverized coal nozzle 6 is enhanced.

Title: Mirror surface plate of laminating printed wiring board and production of printed wiring board using the same
Inventor: TANAGANE OSAMU
IPC: B32B15/08
Filed: 1993-11-24
Abstract: PURPOSE:To obtain a mirror surface for laminating a printed wiring board capable of perfectly removing the resinous foreign matter bonded to the surface of the mirror surface plate and an aligning through-hole by forming a resin film having a carboxyl group to the surface of the mirror surface plate having a flat surface provided with a positioning hole. CONSTITUTION:A metal flat plate having an aligning through-hole 2 provided to the periphery thereof is ground (belt grinding, buffing) to form a mirror surface plate. Subsequently, the mirror surface plate is immersed in an aq. soln. for electrodeposition of a resin having a carboxyl group to uniformly form a resin membrane 3 on the mirror surface plate and this mirror surface plate is washed and dried to obtain a mirror surface plate for laminating a printed wiring board. A prepreg and a multilayered wiring board material are laminated to hold the mirror surface plate and heated under pressure to obtain the printed wiring board. Since the resin membrane 3 on the surface of the mirror surface plate 1 and the resin membrane 3 in the through- hole 2 have the carboxyl group, the resin membrane 3 is saponified by the hydroxyl group of an aqueous alkali soln. to be hydrolyzed. Since a bonded resin is present on the resin membrane 2, the bonded resin can be perfectly removed by the decomposition and peeling of the resin membrane 3.

Title: Hollow cathode type metal ion laser
Inventor: KAWASE HIROMI
IPC: H01S3/03
Filed: 1986-12-11
Abstract: PURPOSE:To enable a multicolor laser beam containing the three primary colors to stably oscillate for a long time by a method wherein a Brewster window and its periphery are constituted of a transparent material with its distortion point higher than the melting point of a metal ion generating material and a laser the is provided with a heat retaining means. CONSTITUTION:A Brewster window 2 and its periphery 2a are constituted of a transparent material, for example quartz glass, with its distortion point higher than the melting point of a metal ion generating material 8. A laser tube 1 is provided with a heat retaining means 60, which retains heat in a region including a hollow cathode 3, auxiliary anode 6, and auxiliary discharge region 30a, of the laser tube 1. In a device designed as such, metal thin film sticking to the inner surface of a Brewster widow may be removed by baking the windows. With the heat retained not allowing a low temperature portion to exist in the auxiliary discharge region or in the vicinity of the auxiliary anode, there will be no crystallization of the metal ion generating material in the auxiliary discharge region or in the vicinity of the auxiliary anode. The laser tube is therefore kept clear of any obstacles along its optical axis, which ensures a long-time sustenance of the initial normal conditions.
