Title: Electron beam welding method
Inventor: MORI TERUO
IPC: B23K15/00
Filed: 1990-10-08
Abstract: PURPOSE:To facilitate electron beam welding without allowing the electrostatic breakdown of an IR detecting element by winding a metallic wire on an outer glass cylinder attached to a 1st metal, putting a metallic rod into an inside glass cylinder attached to a 2nd metal and grounding this metallic rod. CONSTITUTION:The metallic wire 10 is wound around the outside glass cylinder 1. This metallic wire is grounded directly or via another conductor, by which the electrification of electrons on the outside glass cylinder is obviated. The metallic rod 11 is put into the inner side of the inside glass cylinder 4. This metallic rod is grounded directly or via another conductor, by which the electrification of the electrons on the inside glass cylinder is obviated. The 1st metal 1 and the 2nd metal 5 are synchronously rotated and the part of an arrow where these metals are in contact with each other is electron beam welded. The electrostatic breakdown of the IR detecting element 3 by the electrons is obviated and the electron beam welding of the 1st metal joined with the outside glass cylinder and the 2nd metal joined with the inside glass cylinder is executed in this way.

Title: Homogenization of fine crystal chitin suspension
Inventor: YOKOTA HIROSHI
IPC: A23L29/20
Filed: 1984-12-21
Abstract: PURPOSE:To improve dispersion stability at low concn., by imparting high velocity to a fine crystal chitin suspension with pressure difference of 200kg/cm<2> or more and, thereafter, allowing said suspension to collide with the wall body in the vicinity of an orifice outlet to rapidly decelerate the same. CONSTITUTION:When a suspension is flowed into a valve apparatus 1 as shown by the arrow, said suspension is held under high pressure but under a low speed state at the inflow area. The flow speed of said suspension is rapidly accelerated up to 200m/sec by pressure actin as said suspension flowed into the small caliber orifice 3 formed to the gap between the valve 4 and a valve seat 2. Pressure is dropped between the inlet and outlet sides of the orifice 3. The suspension is collided with a collision ring surrounding the orifice 3 when issued from the gap between the valve 4 and the valve seat 2 and the speed thereof is decelerated.

Title: Overcurrent protection circuit of photomultiplier
Inventor: YAMAGUCHI AKIRA
IPC: H04N1/00
Filed: 1989-10-18
Abstract: PURPOSE:To prevent deterioration or breakdown of a photomultiplier by judging whether a signal current is of more than a prescribed value and when an accumulated time for which the signal current exceeds the prescribed value exceeds a prescribed time, lowering the value of voltage applied to a photomultiplier. CONSTITUTION:An accumulated time for which a signal current flowing through a photomultiplier 31 exceeds a prescribed value is found by a comparator 35 and an accumulation circuit 37, and when this accumulated time exceeds a prescribed time T, the value of voltage applied to the photomultiplier 31 is dropped by a power circuit 34. Accordingly, even if a signal light become instantaneously large, the voltage applied to the photomultiplier 31 will resultantly not immediately dropped, but a signal light can be effectively received. Not only in the case of incidence of an external light, but also even if a signal light itself is continuously in an excessively large quantity of light, the voltage applied to the photomultiplier 31 can be dropped. It is thereby possible to effectively prevent deterioration and breakdown of the photomultiplier.

Title: Settling work of concrete pile and concrete pile
Inventor: TAKENAKA SADAO
IPC: E02D7/22
Filed: 1987-10-27
Abstract: PURPOSE:To raise operability of concrete pile settling work as well as increase the bearing force of the pile by a method in which a concrete pile having a number of screw blades on its lower end is rotationally settled down into a pit filled with cement milk under its own weight. CONSTITUTION:Cement milk 13 is injected into a pit drilled by a borer and a hole wall degradation-preventing agent 14, e.g., bentonite liquid, is then injected. A pile 1 having a number of screw blades with sloped blade face is rotationally settled down under its own weight into the pit while spirally scraping the inner wall of the pit. The operation can thus be smoothly performed without noise and the bearing force of the pile can be increased because the recessed portions 15 of the inner wall are filled with concrete.

Title: Fluorescent display tube
Inventor: MORI JUN
IPC: H01J31/15
Filed: 1994-11-04
Abstract: PURPOSE: To prevent unevenness of light emission caused by the charge of negative load, in a fluorescent display tube of such type that a grid electrode is provided at the apex of the rib-shaped wall surrounding a phosphor layer.

Title: Filter circuit
Inventor: HATASHITA HIROSHI
IPC: H04B1/18
Filed: 1985-12-04
Abstract: PURPOSE:To improve the separation of a signal at a high frequency band by connecting the inputs and outputs of filters whose reception bands are continuous via the series connection of >=2 diodes in nonconductive state in plural filters dividing the signal band into plural bands.

Title: Hydraulic pressure booster for vehicle
Inventor: NOMURA YOSHIHISA
IPC: B60T13/12
Filed: 1990-10-08
Abstract: PURPOSE:To improve facility of a hydraulic pressure booster by providing a pressure area increasing means to materially increase the area of a pressure surface where a rear action piston receives power hydraulic pressure in the case when a brake operation force is larger than a standard value on a hydraulic pressure booster for car. CONSTITUTION:When a brake pedal is stepped on, a rear action piston 104 approaches a power piston 66 and power pressure is heightened by a central valve 170, but in the case when a stepping force F applied on the brake pedal is small, an auxiliary piston 140 of a pressure area increasing means 210 does not advance and it is kept at its original position. Subsequently, when the brake pedal is more strongly stepped on from this state and power pressure is heightened higher than the height to balance with a preload of a spring 154, the auxiliary piston 140 advances against the spring 154 and makes contact with the rear action piston 104. Consequently, the area of the pressure surface where the rear action piston 104 receives power pressure comes to be materially larger than the case when the stepping force is small.
