Title: Device for producing thin film
Inventor: SHIMODA MAKOTO
IPC: C23C16/48
Filed: 1987-05-19
Abstract: PURPOSE:To prevent the clouding of the light introducing window of a vacuum vessel and to effectively carry out a light excited reaction by impressing voltage on an electrode placed in front of the window so as to form an electric field and to stick produced fine particles to the electrode and the inner wall of the vessel. CONSTITUTION:In a device for producing a thin film by a light excited reaction, excitation light 30 enters the vacuum vessel 1 through the light introducing window 3 and passes over a substrate 2 held on a support stand 4. At this time, gaseous starting material introduced into the vessel 1 is excited and deposits on the window 31, etc., as fine particles and radicals. In order to prevent the clouding of the window 31 and to increase the rate of deposition of a thin film, a clouding preventing electrode 32 insulated from the vessel 1 with an insulator 21 is placed on the inside of the window 31 and connected to a power source 33 and voltage is impressed on the electrode 32 to such a degree that glow discharge is not caused. An ununiform electric field is formed between the inner wall of the vessel 1 and the electrode 32, so fine particles, etc., produced by a light excited reaction can be stuck to the electrode 32 or the inner wall of the vessel 1 and captured.

Patent JP-H0749097-A (JP)
Title: Fan
Inventor: SENTODA NORIO
IPC: F04D25/08
Filed: 1994-06-01
Abstract: PURPOSE:To provide discharge air of approximately uniform distribution by juxtaposing an intake side wall plate having an intake port and a discharge side wall plate having an annular discharge port in the center of a fan case, forming a circumferential wall plate having a diameter larger from the intake side wall plate toward the discharge side wall plate, and setting an outer diameter of a rotating laminar flow fan main body gradually small from the intake side wall plate toward the discharge side wall plate. CONSTITUTION:Air, which us sucked from an intake port 13 formed in the center of an intake side wall plate 12-1 by rotation of a rotating laminar flow fan main body 11, is discharged in the radial direction by centrifugal force. The discharged air is guided by a tapered circumferential wall plate 18, to be blown out from an annular discharge port 16 of a discharge side wall plate 12-2 juxtaposed with the intake side wall plate 12-1. The outer peripheral surface of the rotating laminar flow fan main body 11 is formed in such a manner that an outer diameter gradually becomes smaller from the intake port 13 toward the discharge port 16. Accordingly, relatively strong air discharging force is generated on the intake side in the axial direction while relatively weak air discharging force is produced on the discharge side. Since the circumferential wall plate 18 for guiding the discharged air is gradually increased in diameter toward the discharge port 16, air blowing-out distribution along the radial direction of the discharge port 16 becomes approximately uniform.

Title: Elution tester
Inventor: MOTOYAMA SHIMESU
IPC: G01N1/00
Filed: 1980-08-30
Abstract: PURPOSE:To perform the elution test accurately and speedily by a method wherein the tester is provided with a container containing a liquid under test and a tank used to heat an auxiliary liquid for testing purposes with a built-in tank for keeping the liquid under test at the specified temperature and a means for heating the auxiliary liquid. CONSTITUTION:A heat retaining tank 14 for keeping the liquid under test is installed on an operating panel 12 of the elution tester, and a container 16 for putting a liquid 18 under test is contained in the tank. In addition, a heating tank 40 for  keeping the auxiliary liquid for testing purposes, made of a transparent material such as glass is attached to the rear side of the tank 14 for keeping the liquid in a one body. The auxiliary liquid 42 for testing purposes has been preheated up to a certain temperature and kept at prescribed temperature by a heater 44 within a heating tank 40. Whenever the liquid 18 is extracted, the exactly same amount of the liquid is supplied to the container 16. In this case, because the liquid 42 newly supplied is kept at the same temperature as that of the liquid 18, no temperature change due to such re-supply occurs. Thus an accurate speedy elution test can always be made.

Title: Piecing method in friction spinning machine
Inventor: KURITA YOSHINOSUKE
IPC: D01H4/52
Filed: 1992-05-13
Abstract: PURPOSE:To uniformize the number of twists for yarns including pieced parts by nonlinearly raising the respective revolving speeds of a false roll and a twisting roll after piecing relatively to winding speed raising. CONSTITUTION:When a yarn breakage occurs in a friction spinning, an air pressure cylinder 3 is actuated to remove a package 2 being in winding from a winder 1, and the package 2 is revolved in the direction opposite to that in its winding using a reverse roller 5 to make a suction of the yarn end with a suction arm 4. In this state, the arm 4 is rotated clockwise to unwind the yarn from the package 2 and the yarn is guided to a wedge zone formed by a false roll 7 and a twisting roll 6 and fixed under suction. Thence, the resulting package 2 is pressed again on the winder 1 and fed with a fiber bundle at a constant speed lower than the normal winding speed along with piecing of the above yarn end, and, in concert with its completion, the winding speed is raised to the normal winding speed; during this process, the respective revolving speeds of the false roll 7 and twisting roll 6 are nonlinearly raised relatively to the winding speed so that the number of twists becomes constant.

Title: Transfer of heat
Inventor: OOMORI TOSHIAKI
IPC: F24D3/02
Filed: 1984-06-12
Abstract: PURPOSE:To permit to transfer heat effectively even when the transfer of heat is effected without employing a circulating pump while even pressure losses in a pipeline and heat radiator are designed to be big enough by a method wherein heat medium is sent out by utilizing vapor pressure and is re-circulated by utilizing vacuum effect. CONSTITUTION:When a heating source 14 is operated, a part of the liquid phase heat medium, poured into a heater 13, becomes saturated vapor, the heat medium in the heater 13 is sent into a heat radiating coil 17 by the pressure of the vapor through a conduit 15 and is reserved into a liquid reserving tank 19 after providing ambient air with the heat thereof. When the level of liquid in the heater 13 is detected by a low liquid level sensor 20 and the operation of the heating source 14 is stopped, the heater 13 is cooled and vacuum is generated in the heater 13 due to the condensation of the vapor existing in the heater 13. When the inside of the heater 13 has become vacuum, the heat medium in the liquid reserving tank 19 recirculates into the heater 13 from a discharging pipe 18 through the radiating coil 17 and the conduit 15. When the liquid level in the heater 13 has become higher than a predetermined level, the heating source 14 is put ON and the heating is started again.
