Patent JP-H03121331-A (JP)
Title: Dynamic damper
Inventor: KATO YOSHIKAZU
IPC: F16F15/124
Filed: 1989-10-04
Abstract: PURPOSE:To securely prevent intermediate speed inner noise caused by a torsional vibration and a high speed inner noise caused by a bending vibration by constituting an elastic member of an intermediate board and elastic parts integrally fixed to both sides of the board. CONSTITUTION:Since an elastic member 3 has a structure wherein an intermediate board 31 is interposed between elastic parts 32, 32, a spring constant of the elastic member 3 along a diameter is increased due to the existence of the intermediate board 31 as well as a spring constant of the elastic member 3 in a peripheral direction is maintained at the spring constant of the elastic part 32 itself. Thus due to the spring constant set small in the peripheral direction of the elastic member 3 with respect to a torsional vibration with a low frequency generated on a propeller shaft, a second cylinder 2 effectively functions as a sub vibration system to the torsional vibration. In addition due to the spring constant set large in the radial direction of the elastic member 3 with respect to a bending vibration with a higher frequency generated on the propeller shaft, the second cylinder 2 effectively functions as the sub vibration system to the bending vibration.

IPC: F16C19/20
Filed: 1985-11-19
Abstract: PURPOSE:To improve the durability by holding a gap between ball members through a gap holding member, thereby smoothing the relative motion. CONSTITUTION:A gap holding member 7 is formed by cutting a steel pipe having smaller outer diameter than a ball member 6 into a fixed length and a bevelled face 8 is formed at the contacting section with the ball member 6. Relative rotation of the members 1, 2 will cause a bearing function through the ball member 6 while a gap between the ball members 6 can be held through the gap holding member 7. Consequently, the relative motion can be smoothed and the durability is improved.

Title: Ion processing device
Inventor: NISHIGAMI YASUAKI
IPC: H01J37/317
Filed: 1994-09-28
Abstract: PURPOSE: To enable a device to detect insufficiency of a plasma supply amount due to clogging of a small hole and the like in a plasma generating device, by comparing a reflector current with a reference value in a comparator circuit. CONSTITUTION: Negative voltage is applied relating to a Faraday cup 8 to a reflector electrode 16 from a reflector power supply 17. In the case of introducing plasma into a plasma generating device 11, since an ion in the plasma 14 is attracted to the reflector electrode 16 of negative voltage, a reflector current flows in a forward direction in the reflector power supply 17. When an amount of the plasma 14, supplied into a Faraday cup 8, is decreased due to clogging of a small hole 13 and the like in the plasma generating device 11, since also an ion, captured in the reflector electrode 16, is decrease, also the reflector current is decreased.  This reflector current is detected by a current detection amount 20, to compare this amount with a preset reference value in a comparing circuit 21, and when the reflector current is smaller than the reference value, an interlock signal S2 is output from the comparing circuit 21.

Title: Vertical semiconductor device
Inventor: KATO NAOTO
IPC: H01L27/02
Filed: 1991-10-07
Abstract: PURPOSE:To improve the breakdown resistance of an element by suppressing the operation of a parasitic transistor at noise current application, in a vertical MIS device. CONSTITUTION:Cells are connected partially with each other by a p-extraction area 4, in respect of a p-base layer 3, which constitutes each unit cell of an n-channel DMOS element, and a p-base layer is short-circuited with a source electrode 9 through the p-extraction area 4 by a region Z2. Hereby, it follows that applied noise is branched into a passage, which leads to the source electrode 9 from the region Z1 via a conventional n<+>-source region 5, and a passage, which leads to the source electrode 9 from the region Z2 via the p-extraction area 4. Moreover, since the p-region forms one continuous area in succession in its entirety of an element, the partial potential rise of the p-base layer is suppressed. By the above, the operation of a parasitic transistor is suppressed, and the breakdown resistance of the element is improved.

Filed: 1992-09-29
Abstract: PURPOSE:To obtain a direct driver having simplified structure in which power is saved while enhancing durability and suppressing noise by providing an ultrasonic motor which rotates a slide nut through a threaded rotary shaft. CONSTITUTION:The direct driver 38 comprises a threaded shaft 22, a slide nut 24, and an ultrasonic motor 44 wherein the slide nut 24 is rotated smoothly through a plurality of balls by means of the threaded rotary shaft 22.
