Title: Thermal protector
Inventor: HARADA TOSHINORI
IPC: H01H37/54
Filed: 1989-12-20
Abstract: PURPOSE:To prevent conductance between contact points from becoming unstable even under vibration and shocks usually encountered by electric appliances by constantly pressing a thermally responding element plate by a tongue attached to a movable electrode plate. CONSTITUTION:Even with a weak spring force of a movable electrode plate 1, a gap is made between a raised portion 1d and a thermally moved element plate 3 and the area from the end to the approximate center of the plate 3 is constantly pressed with a tongue plate 1d. Since a movable contact point 2 is pressed with the end of the plate 3, the contact force between the movable contact point 2 and a fixed contact point 6 is made high so that unstable conductance due to insufficient contact pressure is prevented. Since the base portion 1e and the claw portion 1a of the tongue plate 1b have some gap between the plate 3, repeated returning actions of the plate 3 is not hindered. This prevents conductance between contact points from becoming unstable even under vibration and shocks usually encountered by electric appliances.

Title: Gas-liquid separator
Inventor: KUROKAWA JUNICHI
IPC: B01D19/00
Filed: 1993-12-27
Abstract: PURPOSE:To enhance gas-liquid separation efficiency and reduce pressure loss by providing a small gas-liquid discharge hole in a wall of a vortex chamber equipped with an inlet in a tangential direction, installing a discharge pipe in the discharge opening in the wall opposite to the above wall, and opening a liquid discharge hole, directed toward the vortex chamber, at the center on the midway of a discharge pipe. CONSTITUTION:Liquid discharged from the discharge opening of a pump 3 flows tangentially into a vortex chamber S of a gas-liquid separator, causing swirl A in a discharge pipe 20 following the vortex chamber S. During swirling, liquid with a high specific gravity containing no bubble collects near the internal surface of the discharge pipe 20 and liquid with a low specific gravity collects at the center of the discharge pipe 20. Liquid in a liquid path 18 flows out as a jet B from the discharge opening 21 toward the vortex chamber S through an L-shaped pipe 22. The jet 13 causes counterflow at the center of the discharge pipe 20, raising the pressure of the fluid. The pressure rise works as a pressure barrier, causing a pressure gradient opposite to the swirl A.

Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To perform the numeric analysis of fluid flow in a space including a rotary part accurately and speedily by analyzing an area near the rotary part of an analysis space by the rotary coordinate system equation and analyzing the remaining part by a non-rotary coordinate system equation. SOLUTION: The analysis region of a radius OC is subjected to numerical analysis by dividing the region into three regions, namely a region V1 of the cylindrical part of a radius OA that is smaller than the inner diameter of an impeller 5, a region V2 that is surrounded by the cylindrical part with a radius OB that is larger than the outer diameter of the impeller 5, and a region V3 that is surrounded by the cylindrical part with a radius OC and the region V2 . Then, a rotary coordinate system is used in the region V2 including a rotary part, while a stationary coordinate system is used in the regions V1 and V3 .  Since the region V2 including the rotary impeller 5 is calculated by using the rotary coordinate system, a calculation time can be reduced to approximately 1/100 as compared with that by the time advance method and at the same time non-compression Navier Stokes equation can be applied in the region V2 , so that the result of a numerical analysis has physical meaningful and is fully useful for analyzing an actual centrifugal blower.

Filed: 1990-11-28
Abstract: PURPOSE:To increase the secrecy of data and to prevent a forgery by irradiating the data with light through a transparent sheet for collation where fine parallel lines, orthogonal lattice lines, or a dot pattern for printing is extracted. CONSTITUTION:The recording data are made to appear with moire fringes generated by the light irradiation through the transparent sheet for collation where the fine parallel lines, orthogonal lattice lines, or dot pattern for printing is extracted. Namely, the data are recorded on a recording body with specific- pitch parallel lines, so the data never become unreadable owing to demagnetization caused by lines of magnetic force and the density and angle of the parallel lines (ground tint) are varied in several stages to record much information data on the recording body compactly and display them distinctively. Consequently, the recorded data are hard to disappear, the secrecy of the data is improved, and it becomes difficult to forge the data.
