Title: Solar heat collector
Inventor: IWATA HIDEO
IPC: F24J2/50
Filed: 1979-11-30
Abstract: PURPOSE: To prevent the heat transmission and convection from a heat collecting plate, to improve the heat collection efficiency and simplify a sealing method by providing a reduced pressure space constantly pressure reduced upon collection of heat on the outer face side of the heat collection plate.  
     CONSTITUTION: A heat collection plate 3 is internally provided within a box member 2 made of a transparent plate 1, and a reduced pressure space 4 is formed between the outer face of the heat collection plate 3 and the inner face of the box member 2. An aspirator 6 is arranged in a heat medium pipe 5 for supplying the heat collecting medium, and the reduced pressure pipe 7 of the aspirator 6 is communicated with the reduced pressure space 4. When the heat collection medium is supplied from the heat medium pipe 5, the heat collection medium is heat collected by the heat collection plate 3, and discharged from the heat medium exhaust pipe 5 for exhausting the heat collection medium. Upon this occasion, since the heat collection medium passes through the heat medium pipe 5, the interior of the reduced pressure pipe 7 is brought to negative pressure, as a result of which heat transmission and convection from the heat collection plate 3 are prevented. Further, since a reduced pressure coating is formed upon heating, a relatively simple sealing method may be used.

Title: Laser equipment of lateral excitation type
Inventor: OGAWA TOMOKO
IPC: H01S3/038
Filed: 1993-06-28
Abstract: PURPOSE:To make a distribution of surface electric field intensity in discharge plasma approximately constant from the center to the periphery by forming the section of an electrode in such a way that the distribution of the surface electric field intensity in vacuum increases from the vicinity of the center toward the periphery to reach a maximum in the periphery. CONSTITUTION:A section perpendicular to the longitudinal direction of an electrode 20 used either as an anode 7 or a cathode 8 has a y axis passing through a central point O to serve as a symmetrical axis for symmetry, forming so that the radius of curvature drops from a vicinity 21 of the center toward a periphery 22 down to a minimum of 23 at the periphery. A distribution of surface electric field intensity when a voltage is impressed in vacuum on the electrode 20 rises from the vicinity 21 of the center to the periphery 22, reaching a maximum of 24. Also, the distribution of the surface electric field intensity at the electrode 20 in discharge plasma becomes approximately constant from the vicinity 21 of the center toward the periphery 22, and its tendency to become more intense than in the periphery is inhibited. Consequently, uniform and stable high-density discharge and high-efficiency oscillation are made possible.
