Title: Tail plug for ink tank for writing utensil
Inventor: KOJIMA MIKIO
IPC: B43K5/14
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent the top part of a tail plug for an ink tank at the time of ultrasonic welding from being damaged by forming a rib whose wall becomes gradually thicker from the center side to the peripheral side, inside the top part of the tail plug installed airtightly on the ink tank by welding. SOLUTION: A welding part 2A formed in crest shape on a tail plug 2 is brought into contact with the rear end 1A of an ink tank by a horn generating ultrasonic oscillation. Thus, the tail plug 2 is welded to the ink tank 1 by ultrasonic wave by fusing the welding part 24. In this case, the tail plug 2 has a rib 2D whose wall becomes gradually thicker from the center side to the peripheral side, formed at the part excepting the inside center part 2C of a top part 2B. In addition, the center part of the top part 2B for the tail plug 2 is caused to oscillate by applying ultrasonic oscillation to the tail plug 2 with the horn. Further, this oscillation is transmitted to the rib 2D and in turn, to the crest- shaped welded part 2A, so that the welding part 2A of the plug 2, for example, for an ink cartridge is welded to the rear end 1A of the ink tank 1.

Title: Electrostatic chuck of plasma treatment apparatus
Inventor: TSUKADA TSUTOMU
IPC: H01L21/68
Filed: 1993-07-16
Abstract: PURPOSE:To attract a substrate to a substrate holder even if a plasma is not generated and make the substrate attracted uniformly while the plasma is generated by a method wherein the potential relation state of a plurality of buried electrodes are switched between an equipotential state and a non-equipotential state. CONSTITUTION:A first buried electrode 20 is always connected to a radio frequency applying electrode 16. If the position of a substrate holder 12 is elevated, a second buried electrode 21 is connected to the radio frequency applying electrode 16 through a moving element 30. At that time, the electrodes 20 and 21 are in an equipotential (-500 V) state. If a negative self-bias voltage (approximately -100V) is given to a substrate 22 by a plasma, a potential difference is induced between the upper and lower surfaces of a dielectric layer 18 and the substrate 22 is attracted to the substrate holder 12 by an electrostatic force. If the substrate holder 12 is made to descend, the electrode 21 is connected to a voltage introducing terminal 42 and a potential of -1000 V is given to the electrode 21 and the electrode 20 is grounded. In this state, the substrate 22 is still attracted to the substrate holder 12.

Title: Valve
Inventor: ASAMI TAKASHI
IPC: F16K27/04
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To relax the sudden flow of a fluid effectively, by advancing the front end of a valve body in a fluid passage, so as to block the fluid passage making narrower gradually from the upstream side toward the opening position of a fluid pressure leading-in hole, when the valve body is in the advancing position, and retreating the front end from the fluid passage, when the valve body is in the retreating position. SOLUTION: When a sudden bursting fluid is led in through an opening end 11, the front end 41 of a valve body 4 advances in a fluid passage 1, and blocks the passage perfectly at the part other than the initial clearance, so as to block the flowing. In this case, the fluid enters in the fluid passage part throttled to make narrower gradually between the bending spherical surface of the front end 41 of the valve body 4, and the inner circumferential surface of the fluid passage 1, and transmits a static pressure to the hollow part 42 of the valve body 4 through a fluid pressure leading-in hole 43. This pressure is reduced relatively to the pressure operating to the outer side of the valve body from the upstream side upper than the fluid pressure leading-in hole 43, and it moves the valve body 4 by energizing in the retreating direction gradually, and opens the fluid passage 1 to increase the passing amount gradually. And in the retreating condition, the valve body 4 moves while discharging the fluid in the hollow part 42.
