Title: Rotary compressor
Inventor: YOSHIMURA TAKAO
IPC: F04C27/00
Filed: 1988-03-04
Abstract: PURPOSE:To elongate the sealing distance between the opposing end faces of a roller and both bearings and improve the efficiency by forming approximately circular grooves of which each one end is communicated with the internal peripheral part of the roller and the other end is near that internal peripheral part, on each of the opposing end faces of the roller opposed to a main bearing and a supplementary bearing. CONSTITUTION:One end face 19a of a roller 19 is opposed to a main bearing 7 and the other end face 19b is to a supplementary bearing 8. A plurality of circular grooves 20 to 23 are formed on one end face 19a and communicated at one ends with the internal periphery of the roller 19 and extend to the other ends near the internal periphery of said roller 19, that is, not communicated therewith. The opposite end face 19b of the roller 19 has the same number and the same form of the grooves as on the end face 19a. When the grooves 20 to 23 are supplied with lubricating oil, since the end parts 20b to 23b are not communicated with the internal periphery of the roller, the pressure rises due to the self-revolution action of the roller 19, whereby maintaining the clearance between each of the bearing and the roller 19 equal, elongating the sealing distance due to the circular form and improving the efficiency.

Abstract: PURPOSE:To measure the eccentric amount of the grid-electrode hole of a color- television electron gun accurately through optical measurement by removing both the shift of the optical axis of an optical device and the picture strain caused by a visual sensor. CONSTITUTION:Illumination light emitted from a light source 13, after being transmitted by grid-electrode holes (a-f) of an electron gun 10, enters into an imaging optical device 5, enters through an objective lens 19 and half mirros 16a, 16b, 16c and 16d into a first light path (P1), and travels through a lens 17a of the path (P1) into a visual sensor 4. Following that, hole images caught by the visual sensor 4 are passed through a controller 20, and are subjected to information processing by means of an arithmetic unit 21 and a monitor 22. Thus, the center eccentric-amount of the above electrode hole (c) is measured by comparing it with the center coordinate of the hole image of a first grid- electrode 1a which is formerly computed.

Abstract: PURPOSE:To improve inputting operability, by deciding the indication range of a character string required for correction/editing based on a count value from a character number counter means, and executing the correction/editing of the character string corresponding to the indication range. CONSTITUTION:By operating a shift key on a keyboard 14, a CPU 10 starts the execution of a shifting process for a correction/editing mode. The CPU 10 sets '1' as a character number count value N to count the number of characters in the character string within a range indicated from a start position, and displays a message to indicate the number of characters in the character string on a liquid crystal device (LCD device) 13. When the shift key is operated corresponding to the message, N-number of characters are increased by every operating number of times of the shift key, and a cursor is moved digit by digit from the start position of the character string at every operation of the shift key. In this way, the CPU 10 detects the indication range of the character string to be moved by the value of N-number of characters, and instructs the character string within an indicated range on a display screen.
