Title: Seal ring for ball valve
Inventor: SHINOHARA MORIMICHI
IPC: F16K5/20
Filed: 1978-09-18
Abstract: PURPOSE: To reduce waer of the seal case and permit smooth operation of the seal ring by providing frictional rings on the surface of a seal ring in contact with a seal case.  
     CONSTITUTION: Frictional rings 21 made on a soft non-ferrous material having a low coefficient of friction, for instance gun metal, are secured to a seal ring 20 at opposite edges thereof. A frictional member 31 made of a hard material such as stainless steel is secured by means of fusion to the inner surface of a seal case 5 in contact with packings 23. When the seal surface C is brought into close contact with the movement of the seal ring 20 caused by applying water pressure P 2  for cutting water flow W, smooth relative movement of the frictional member 31 and frictional ring 21 is caused. Even when the corner of the frictional ring 21 touches the frictional member 31, the corner is worn only slightly. Gaps G 2  and G 3  are smaller than gaps G 1 , G 4  and G 5 , so that the opposite edges of the frictional ring 21 is always in contact with the frictional member 31.

Filed: 1990-04-27
Abstract: PURPOSE:To recognize respective feature areas by one image pickup means by providing a setting means to set a threshold value by every partial area toward plural partial areas divided in the direction of a scanning line against a picture image-picked up by the image pickup means. CONSTITUTION:An operator turns the inspection area of a monitoring object to a normal state, image-picks up this inspection area by a television camera 2 and projects it on a CRT 4a to decide whether how many the number of the partial area is, and what number of the scanning line is the boundary between the partial areas, etc. The operator decides a threshold value Vthi in the respective partial areas to store them through a write pen, etc., in a RAM 23. A binary encoding signal, processed binarily the inspection area of the threshold Vthi in the normal state, is stored in the RAM 23 as a reference picture data. Thus, the recognition objective having plural feature areas with different optimum threshold values can be monitored by only one image pickup device.

In this manner, the volume of the high pressure chamber is substantially varied in accordance with the set injection quantity, so that, even when the injection quantity is varied, the injection pressure can be maintained constant. This enables reduction in the exhaust emission. Note that, as another means for varying the volume of the high pressure chamber, a variable high pressure chamber capable of displacing the piston with a fuel pressure in the high pressure chamber 2a may be provided.

Filed: 1989-05-09
Abstract: PURPOSE:To efficiently neutralize electrification of a wafer by providing insulation means for electrically insulating a tube portion and a target portion from each other, and grounding means for grounding the tube portion. CONSTITUTION:Insulation means 123 is provided for electrical insulation between a tube portion 121 for regulating the passage of an ion beam 13 and a target portion 122 emitting secondary electrons, and a tube portion 121 is grounded by a grounding means. Most of secondary electrons emitted by the ion beam 13 from a disk and a wafer 11 collide the tube portion 121 and are allowed to pass onto the ground, so that detection of the secondary electron current corresponding to the secondary electrons emitted from the target portion 122 is enabled without being influenced by the secondary electrons emitted from the disk and the wafer 11. Secondary electrons are therefore emitted from the target portion accurately, i.e., by the amount corresponding to a preset amount, and electrification of the wafer is efficiently neutralized.
