Title: Plasma chamber with improved valve closure
Inventor: ISHIKAWA TETSUYA
IPC: C23F4/00
Filed: 1994-03-16
Abstract: PURPOSE: To eliminate the generation of local distortion of plasma, so as to enable the even processing of wafer by forming an opening of a chamber such that the inner surface of the opening is formed into nearly identical shape with other parts of the inner wall, when the opening of the chamber is closed by a valve closure. CONSTITUTION: A valve closure 5 evenly and tightly makes contacts with an opening so as to seal a chamber during the operation, except for the time of inserting and eliminating semiconductor wafers. A plasma chamber has a cathode for supporting wafer, so as to receive the semiconductor wafer from a wafer robot arm. A shoulder part 40 of the closure is extended from a base to a tight contact part inside of the opening. A curved surface 42 on the shoulder part 40 is formed so as to match the shape of the inner surface of the chamber. When the valve closure 5 is closed, the inner wall thereof forms a nearly even inner wall, without generating a level difference between an adjacent part of the inner wall surface of the chamber so that plasma is generated uniformly in the chamber.

Title: Ink jet head
Inventor: YASUHARA MASATOSHI
IPC: B41J2/045
Filed: 1989-02-27
Abstract: PURPOSE:To perform stable discharge of a liquid drop and to shorten an ink supply path of an ink reservoir by a method wherein a porous member absorbing vibration is established to an inner wall on the ink supply path side of the ink reservoir, and a pressure wave is damped by absorption before entering the ink reservoir. CONSTITUTION:A pressure wave generated in a pressure chamber 2 is propagated as ink discharge energy in an ink discharge orifice 1 direction and besides, is propagated also in an ink reservoir 5 direction through an ink supply path 3. However, since the pressure wave propagated in the ink reservoir 5 direction is damped by absorption with a porous member 4 provided to an inner wall 5a on the ink supply path 3 side of the ink reservoir 5, it is propagated neither to an inside the ink reservoir 5 nor is again propagated to the pressure chamber 2 side. Since holes of the porous member 4 for absorbing vibration are arranged regularly in a same direction, there is no resistance for permeation of ink, and no ink comes to stay in the porous member 4. No clogging is generated, ink supply is stabilized, and discharge of an liquid drop is never disturbed.

Title: Screw propeller
Inventor: HOSHINO TETSUJI
IPC: B63H1/14
Filed: 1988-02-29
Abstract: PURPOSE:To improve the efficiency of propulsion at the fan blade portions of propeller fans provided protrudingly and radially from a propeller boss, by making a formation so that the rear edges of fans may extend to the tip portion of the propeller boss. CONSTITUTION:An extension fan 3 formed by the backward extension of the rear edge 1b of the fan, accelerates the current at the rear part of a propeller boss 2 as it rotates in one body with a propeller fan 1, and generates propulsion. Thus, not only the rear current of the propeller fans 1 but also the rear current of the propeller boss 2 is accelerated by means of the extension fans along the tip portion of the propeller boss 2, and as a result, propulsion is generated even at the part of the propeller boss 2 where resistance was generated in the case of a prior screw propeller, so the drastic improvement of propulsion efficiency can be realized. Also, the fitting strength of the propeller fans 1 to the propeller boss 2 can be increased.

Title: Apparatus for reducing water content of coal
Inventor: HASEGAWA SHIGEO
IPC: F26B17/04
Filed: 1987-03-03
Abstract: PURPOSE:To reduce the water content of coal at high working efficiency with less consumption of energy and accomplish drying of coal on carriage, by sandwiching coal between a lower coal conveyor and an upper adsorption dehydrating belt and performing dehydration of the coal during transportation thereof. CONSTITUTION:Coal 5 containing adherent water is put in a coal feeder 1 and continuously fed to a coal conveyor 4. The coal on the conveyor 4 is brought into contact, in the course of the moving of the conveyor 4, with an upper belt 3 composed of a water adsorptive and desorptive polymer which belt has been disposed so as to face the conveyor 4. This causes the water adhered to the coals to be absorbed by the polymer. As a result, dry coal 6 is continuously prepd. from an end of the conveyor 4. The water adsorbed to the polymer is desorbed when the belt 3 passes through a drier 2. Representa tive examples of a usable water-swellable rubbery polymer include gum arabic, polyvinyl alcohol, methylcellulose and open-cellular polyurethane foam.
Patent JP-H04285409-A (JP)
Title: Drive controller for electric automobile
Inventor: ARAI YOSHIHIDE
IPC: B60L11/18
Filed: 1991-03-12
Abstract: PURPOSE:To prevent insufficient acceleration due to consumption of battery. CONSTITUTION:Only when torque is zero, voltage of a battery 10 is taken in through a voltage sensor 15 and a current command is calculated and then outputted. During an interval when the torque is being produced, the battery voltage at the time of zero torque is maintained and control is executed based on thus maintained battery voltage. Since the current command value is determined while following up battery consumption, insufficient acceleration does not occur. Furthermore, since the battery voltage is detected only when the torque is zero, variation of voltage due to battery consumption can be reflected accurately on the control.
