Title: Unbalanced vane pump
Inventor: BON HYUN JO
IPC: F04C2/344
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To prevent the heat generation and wear and attain a high-pressure and high-speed rotation by constituting a rear body formed so as to have a vane oil passing port for pressing a vane and a cylinder oil passing port for supporting a cylinder ring on a bearing side. SOLUTION: In this vane pump, the upper end of a vane 32 is more strongly brought into contact with the inner surface of a cylinder ring 28 by the pressure of the oil carried thereto from the discharge passage of a rear body 42 through the oil passing port 33 of a vane back pressure chamber as the pressure increases. Further, since, the pressure carried into a needle bearing 22 formed on the outside of the cylinder ring 28 through the oil passing port 31 of a cylinder back pressure chamber adds a pressure to the outer surface of the cylinder ring 28, the pressure is maintained equally between the outer surface and inner surface of the cylinder ring 28. Accordingly, since the deformation of the cylinder ring 28 by pressure can be suppressed to minimize the friction force with the needle bearing 22, a high-pressure and high-speed rotation can be performed.

IPC: H05K5/00
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To prevent a printed board from getting a play in a horizontal direction even if a large dimentional error exists is the printed board. SOLUTION: In holding a printed board 40 in a printed board containing box 10 comprising a lower side casing 20 and an upper side casing 30, abutting walls which hold the printed board 40 therebetween are so constituted as to be a fixed wall 22a having a vartical wall and a horizontal wall on one side and oblique walls 22b having oblique faces on the other side. Therefore, when the printed board 40 is pushed down by the abutting walls 32 of the upper side casing 30 after it is suitably contained in the lower side casing 20, the printed board 40 slides down along the oblique faces on the side of the oblique walls 22b to be pushed against the side of the vertical face 22a, thus it is held without having any gap in a width direction.

Title: Plasma generator
Inventor: SUEZAWA HIROKI
IPC: H01J37/08
Filed: 1990-09-20
Abstract: PURPOSE:To get a plasma generator with a large discharge current by a method wherein the material constituting an anode is lower in work function comparing with the material constituting a first cathode. CONSTITUTION:As thermoelectrons repeat a reciprocating motion through the hole of an anode 2 in a space specified by a filament 1 and a cathode 3, the operating gas injected from a filling pipe 10 acts on the thermoelectrons to be ionized through electronic dissociation so that the gas is made into plasma. As a material whose work function is lower than a first cathode is used for the anode, the anode 2 itself is heated by the heat generated caused by the radiant heat from the filament 1 and collisions of thermoelectrons with the anode 2 due to the reciprocating motion of a thermoelectrons so that thermoelectrons are made to be generated from the anode 2. These thermoelectrons electrically neutralize the plus ions of raw material gas centralizedly distributed near the anode 2. It is thereby possible to quicken the release of many thermoelectrons so that discharge current is made larger.
