Abstract: PURPOSE:To neutralize space charges with a simple means by providing a gas feeding means at one portion of the transportation path of a metal ion beam, and keeping the degree of vacuum at a specific value. CONSTITUTION:A flow regulator 32 and a gas guide port 34 are provided at a portion of a vacuum container 18, the gas 30 from a gas source is introduced into the vacuum container 18 through them, and the gas 30 is fed to the transportation path of a metal ion beam 16 extracted from a metal ion source 2 at this portion. When the degree of vacuum at one portion of the transportation path is kept at 10<-3>-10<-2> Pa level, collisions occur between the metal ion beam 16 and gas molecules, beam plasma containing negative charged grains mainly made of electrons is generated, space charges can be effectively neutralized, and the divergence of the metal ion beam 16 can be suppressed.

Title: Ink jetting printer
Inventor: OOMORI HIDEYUKI
IPC: G06K15/10
Filed: 1979-04-13
Abstract: PURPOSE:To eliminate the gain regulation of the voltage amplifier associated with changes in the nozzle replacement, ink beam position adjustment and charging efficiency by controlling the gain of the voltage amplifier so that the output of the voltage amplifier at the optimum phase is invariably held within the prescribed voltage. CONSTITUTION:The signals F and F/n from the phase shift circuit 13 and the single DIN from the converter D are inputted into the gain regulation circuit 50. When the gain of the voltage amplifier 24 is too small, under the phase condition of n, the output vo of the smoothing circuit 25 changes to L from VF2 while the output of the latch 66 goes to L. After the end of the n phase checking, the signal of F/n is inputted to the up/down counter 65 for down counting. When the counter is H (high level), the switches 61-64 are closed. The down counting increases the total value of the feed back resistances 71-74 resulting in an increase in the gain of the amplifier 24. At the same time, the entry of the signal F/n clears the latch 66.

Title: Pump device for power steering device
Inventor: INAGUMA YOSHIHARU
IPC: F04C14/26
Filed: 1986-02-28
Abstract: PURPOSE:To easily obtain a drooping characteristic and to reduce the driving force of a pump by varying the cross-sectional area of a discharge side throttle passage by means of a control spool which is displaced in accordance with a jet pressure on the discharge side of a pressure working fluid. CONSTITUTION:The velocity of a fluid in a discharge passage 28 is increased with the increase in the speed of rotation of a pump rotor 14 and, at the same time, as a jet pressure is increased, a control spool 36 is displaced to a throttle member 38 side against the pressing force of a spring 39 due to the jet pressure which acts on a pressure receiving part 43. Thereby, the cylindrical part 41 of the control spool 36 makes a throttle passage 37 a throttling condition, increasing pressure difference across the throttle passage 37. The increase pressure difference across the throttle passage 37 causes a spool valve 31 to be displaced, increasing excessive flow which is bypassed to produce a desired drooping characteristic.

Title: Chain tensioner device
Inventor: MAEKAWA KEIICHI
IPC: F16H7/08
Filed: 1989-02-28
Abstract: PURPOSE:To maintain the chain tension and prevent the generation of the noise by forming a central part transverse to a pad surface provided in a plunger pressed surface of a chain guide with the rigid material and forming both sides with the elastic material, and contacting the central part and both sides to a plunger end surface and a case end surface respectively. CONSTITUTION:Under the normal condition of a chain tensioner 25, a plunger 37 projects from a case 35 to press a pad surface 27. Under this normal condition, since the plunger 37 mainly contacts to a central metal material part 29, the friction between the plunger 37 and the pad surface 27 is small. Consequently, even if a chain 17 is vibrated to affect the force to the direction transverse to the sliding direction in the case 35 of the plunger 37, the force affected to the plunger 37 is very small, and the sliding resistance of the plunger 37 becomes small. Therefore, the damping characteristic of a tensioner 25 is hardly changed, and the pressing force of the plunger 37 to the pad surface 27 is stabilized to maintain the chain 17 with the requested tension, and the generation of the noise is reduced.
