IPC: E06B3/66
Filed: 1983-02-24
Abstract: PURPOSE:To obtain the titled spacer with high work efficiency by sealing a desiccating agent in a hollow rodlike rough body for a spacer, pressing the rough body at three positions in the form of V-shaped grooves, and bending the rough body to right angles at each pressed part to form a square frame. CONSTITUTION:A desiccating agent is sealed in a hollow, square and tubular rough body 1 for a spacer having a length almost equal to the peripheral length of glass plates for forming pair glass, and both ends of the rough body 1 are clogged. Small holes through which moisture passes without dropping the desiccating agent are pierced in the face of the rough body 1 corresponding to the inside of the spacer, and the face of the rough body 1 is pressed 3 at three positions in the form of V-shaped grooves. The rough body 1 is then bent to right angles at each pressed part 3 to form a square frame. Thus, the desired spacer 9 is obtd. The spacer 9 is put between two glass plates so as to hold a space of a fixed thickness in the resulting pair glass.

Title: Preparation of blue sapphire
Inventor: KATO EIJI
IPC: C30B33/00
Filed: 1985-02-18
Abstract: PURPOSE:To dissolve iron in the whole body of a crystal in the form of solid solution and to obtain blue sapphire having no uneveness of color by keeping a sapphire prepd. in a specified device in hot iron oxide powder under specified conditions, then cooling slowly. CONSTITUTION:Blue sapphire prepd. in a prepn. device of single crystal of condensed heating with infrared rays is kept in iron oxide powder at 600-1,500 deg.C for >=5hr, and cooled slowly. Thus, aimed blue sapphire is obtd. If the temp. for keeping is <=600 deg.C, solid solution of iron is not formed on the surface of the crystal, so there is no influence on coloring. If the keeping time is <=5hr, similar result is obtd. If the temp. is >=1,500 deg.C, sintering occurs because the m.p. of iron oxide is ca. 1,500 deg.C. In this case, the crystal is not taken out with ease, so the condition is inadequate.

Title: Manufacture of carbon compound, and its device
Inventor: IDENO YUTAKA
IPC: C23C14/28
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a film excellent in adhesion to a substrate by flowing a rare gas in a gap between a pair of graphite electrodes stored in a vacuum container to generate a pinch plasma, irradiating the surface of at least one electrode with the laser beam, and incorporating a carbon cluster caused by the ablation from the graphite into the plasma. SOLUTION: When a columnar plasma is generated, the graphite of an electrode 1 is ablated by the laser beam 12 irradiated from a laser beam oscillator 17 toward the electrode 1 through an optical window 8 to emit much carbon cluster. The carbon cluster is strongly excited in the high-temperature and high-pressure field of the pinch plasma in the pinch plasma 3 incorporating the carbon cluster. When the plasma is pinched, the plasma rapidly loses its electromagnetic force, and diffused at a high speed together with the carbon cluster 40 excited in a non-balanced condition, and collided with a substrate 41 installed in a vacuum container 5, and rapidly cooled. By repeating this, the carbon cluster is deposited on the substrate 41 to form a carbon film of excellent quality.

Filed: 1980-03-12
Abstract: PURPOSE:To obtain a focusing action only in one direction with a control electrode, by dividing the control electrode provided between a cathode and anode into a plurality of elements and applying two different potentials to the plurality of electrode elements. CONSTITUTION:A control electrode is constituted by electrode elements 4, 5, 6, 7.

Filed: 1993-02-22
Abstract: PURPOSE: To expand cooling area without changing structure of an engine block by producing sleeve, cylinder liner, and a plurality of circumferentially spaced venturi throats connecting a lower annular cooling chamber with an upper annular cooling chamber. CONSTITUTION: Cylinder liner 30 and split sleeve 150 are secured in cylinder inner cavity. During working of an engine 10, cooling water is circulated on the cylinder liner 30 from a lower cooling chamber 34 to an upper cooling chamber 32 through circumferentially spaced and extending venturi throats 196 and a passage 182. The venturi throats 196 provide a relative long flow path and control the flow rate of the cooling water communicated from the lower cooling chamber 34 to the upper cooling chamber 32 in order to dissipate the heat away from the cylinder liner 30 and piston assembly 92 to surrounding area of the upper ring turn. By this manner, the cooling area can be expanded without changing structure of the engine block.
