Title: Water sealing device
Inventor: MORIYA NOBUO
IPC: F23K5/00
Filed: 1994-03-30
Abstract: PURPOSE:To trap a gas carrier water by a gas-water separator, and guarantee a stable combustion by a flare stack burner by a method wherein the gas-water separator is provided in the middle of a gas passage from a water sealing tank to a flare stack, and a separated water return passage is provided between the gas-water separator and water sealing tank. CONSTITUTION:A gas-water separator 26 is provided in the middle of a gas passage from a water sealing tank 2 to flare stack 1, and a separated water return passage 27 is provided between the gas-water separator 26 and water sealing tank 2. In this case, water accompanying with a combustible gas is separated, and enters the separated water return passage 27. Since the separated water return passage 27 constitutes a communicating pipe to connect the gas-water separator 26 and the water staying part of the water sealing tank 2, it is balanced when a water level L1 at the standing part meets a water level L2 in the water staying part of the water sealing tank 2. Therefore, the water which enters the separated water return part works to increase the water level in the water staying part of the water sealing tank by a head difference between L1 and L2, and a water level decrease due to an entrainment is quickly compensated. That is, a water content which flows out from the water sealing tank accompanying with the gas is almost completely trapped.

Title: Semiconductor device
Inventor: YANADA SHIYUUJI
IPC: H01L23/552
Filed: 1982-04-13
Abstract: PURPOSE:To prevent the light beam which is directly striking the element region of IC by forming an adequate form of metal thin film to be used for wiring, employing multi-layered wiring structure and by adequately arranging a metal thin film as the light shielding procedures. CONSTITUTION:Metal lead width is widened, not like a lead wire, as shown as 11, 12, within the layer to which it belongs as covering such layer. When a multilayered wiring structure is thus formed, gap formed in each layer is filled with metal wirings of other layers, perfectly shielding the light beam. Namely, the light beam is shielded at least at any one of the metal wirings of the first, second and third layers. Increase of floating capacitance due to widened metal wiring width can be prevented by locating a narrow width wiring just under the wide width wiring. Deterioration of integration density of IC due to widened width of lead wire can be compensated by employing multi-layered wiring structure.

Title: Method for letting gauge indicator emit light and light-emitting structure of light-emitting indicator
Inventor: KOMOTO MASUYUKI
IPC: G12B11/04
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To suppress the attenuation of light of a light source and constitute an inexpensive light-emitting indicator in a simple structure by forming the shaft of a rotator of a meter and the indicator of the meter out of a light- transmitting member and connecting the shaft and the indicator light-guidably. SOLUTION: The shaft 1 for a rotor and the indicator 2 of a gauge are formed out of the same medium and connected to communicate therebetween light-guidably. The light from a light source 3 is projected to one end of the shaft 1. The incident light from the light surface 3 comes outside through the shaft 1 and indicator 2, and therefore the indicator 2 appears as if it emitted light. Since the shaft 1 and indicator 2 are of the same light-guidable medium and the light is projected once from the light source 3 to the lower end face of the shaft 1, the light is never attenuated. In this constitution, the indicator 2 is changed to seven colors depending on a vehicle velocity, enabling a driver to recognize the vehicle velocity through the sense of color. The indicator can be designed to be economic and compact with complicate electric parts eliminated.
