Title: Improvement of linear bearing
Inventor: ROBAATO SHII MAGII
IPC: F16C29/06
Filed: 1981-06-25
Abstract: A ball bearing for linear motion which is particularly useful in applications where the "open type" ball bearing is in combination with a shaft supported along its length which is subjected to radial forces primarily toward or away from the open side of the bearing. The ball bearing for linear motion consists of a bearing sleeve adapted to position a plurality of bearing segments on its inside surface. Each bearing segment contains a closed loop of circulating balls. The closed loop has one straight track of load bearing balls and one straight track of non-load bearing balls. The bearing segments are circumferentially positioned within the bearing sleeve so as to maximize the capacity of the bearing when load is applied either toward or away from the open side of the bearing.

Title: Monitoring method of silicon dry etching
Inventor: TSUKADA TSUTOMU
IPC: G01N21/62
Filed: 1982-06-11
Abstract: PURPOSE:To make it possible to monitor with accuracy and easiness the advance and finish of dry etching of silicon by monitoring light emission spectrum intensity of CCl or OH in the process to perform dry etching of silicon. CONSTITUTION:The peak wave length of light emission spectrum intensity of CCl or OH to be monitored is near 307nm. The light emission intensity of those wave lengths is measured and monitored, using a conventional light emission spectroscopic analyser. In the polysilicon etching the light emission spectrum intensity B of wave length 305nm decreases and the light emission spectrum intensity A of wave length 396nm keeps a certain value that is determined by discharge intensity. The difference A-B between them increases output only during polysilicon etching, and as soon as Si etching is finished, the difference decreases to the output before starting polysilicon etching. By this phenomenon the end point of polysilicon etching can be exactly detected.

Filed: 1978-08-18
Abstract: PURPOSE: A cushion which is equipped with various flexible projections at the attaching surface of the frame for the cushion and prevents the relative movement between the cushion and frame contact position and avoids the generation of abnormal noise.  
     CONSTITUTION: A small flexible projection; 4, is positioned in many quantity in the attaching surface of a frame 2 under lower side of a cushion 1 and the small projection 4 is in contact with a cushion spring 3 of the frame 2.

Filed: 1992-04-21
Abstract: PURPOSE:To supply toner to a hopper with a compact constitution by providing a path for replenishing the toner to a toner hopper so as to cross an exposing path to an image carrier and additionally providing a replenishment restricting means. CONSTITUTION:Untransferred toner remaining on a latent image carrier 1 is removed by a cleaning blade 3, and automatically collected in a recovered toner tank 4. Then, recovered toner crosses the exposing path 9 to the latent image carrier 1, passes a replenishing path by gravity, and reaches a slit-like replenishing port 10d to be replenished to the toner hopper 2 from a slit-like replenishing port 10u. When the exposing path 9 is clogged with the toner replenished to the toner hopper 2, a latent image can not be carried on the latent image carrier 1, so a shutter 11 as the replenishment restricting means restricting the replenishment of the recovered toner is provided on the upper part of the replenishing port 10u, and controlled so as to close at the time of exposing, and open at the time of nonexposing. Thus, the disturbance of the latent image on the latent image carrier 1, caused by the interception of exposing light by the recovered toner, can be prevented.

Abstract: PURPOSE:To select a desired graphic form even when the graphic forms are superposed by dividing a picture to specified extents, registering the graphic number of a graphic form that passes the divided area, and reading out graphic forms that pass the area successively from a memory. CONSTITUTION:When a user inputs a point P0 on a displayed picture 10 from an inputting device 11, coordinate value of P0 is read in a processing device 12, and an area in which P0 passes is calculated. When the user designates a point in an area S5, it is judged that a graphic form 21 passes the area S5 referring to a table 30 on a memory 13. The distance between the point P0 and graphic form 21 is calculated, and if it is within a specified range of distance, a processing device 12 judges that the user desires the graphic form 21, and selects and displays the graphic form 21 on the displayed picture 20. However, if it is not within a specified range of distance, the table 30 is referred to again as to whether there is other graphic forms that pass S5. After judging that a graphic form 22 passes S5, the distance is calculated similarly with the graphic form 21, and if it is within a specified range, the graphic form 22 is selected and displayed.

IPC: F16J3/04
Filed: 1988-04-26
Abstract: PURPOSE:To prevent any expansive deformation in the bellows radial direction from occurring by forming wall thickness of a root part in the inner part of a bellows into being thicker in ring form. CONSTITUTION:Wall thickness T in a wall thickness part 4 of a rotor part of a bellows 1 is formed into being thicker than that (t) of an incline 5 as much as a portion for thickness shown in a double hatching 4a.
