Title: Apparatus having element moved along circular orbiting path
Inventor: HIRAGA MASAHARU
IPC: F01C17/06
Filed: 1981-03-23
Abstract: PURPOSE: To reduce the weight of a movable ring and a movable ball race, by making the diameter of pockets formed in the movable ring smaller than that of pockets formed in a fixed ring, and making the inner diameters of the movable ball race and the movable ring large while decreasing their outer diameters.  
     CONSTITUTION: In causing movement of a movable scroll member 21 along a circular orbiting path, it is necessary to prevent turning of the member 21 around itself. According to the present invention, it is achieved by holding ball elements 224 between the marginal portions of pockets 222a formed in a fixed ring 22 and those of pockets 215a formed in a movable ring 215. The arrangement is such that the diameter of pockets 215a of the movable ring 215 is made smaller than that of pockets 222a of the fixed ring 222, and the inner diameters of the movable ring 215 and movable race 214 are increased while decreasing the outer diameters of them, whereby it is enabled to reduce the weight of the movable ring 215 and movable ball race 214.

Title: Stopping device for pallet conveyor
Inventor: SHINKAWA MAKOTO
IPC: B65G47/88
Filed: 1985-02-28
Abstract: PURPOSE:To enable a pallet conveyor to start moving again smoothly after the conveyor has stopped because of an emergency by configurating the device in such a manner that a rear stopper, which is engaged with a projection arranged underneath a pallet, is normally energized upward with low pressure, simultaneously, the stopper is allowed to move back and forth on the transfer path. CONSTITUTION:When a pallet 10 reaches the stated position, a cam follower 11a comes in contact with a rear stopper 17, which is subjected to a small upward force by a spring 26, and then is stopped while the follower is touching with a shock absorber 19. Subsequently, a cylinder 24 is activated allowing a front stopper to come in contact with a cam follower 11 located at the forward end side permitting it to touch a guide block 15. Simultaneously, the cam follower 11a at the after end side is allowed to come in contact with a rear guide block 16 by means of the rear stopper 17 permitting the cam follower (11a) to be positioned. Subsequently, a cylinder 20 allows a link 18 to be tilted so as to release the stopper 17 from the cam follower 11a allowing the pallet 10 to start moving again. This configuration prevents the pallet from being pushed up when not driven enabling it to start moving again smoothly.

Title: Hard copy apparatus
Inventor: YUI YOSHIO
IPC: G03B27/32
Filed: 1979-04-06
Abstract: PURPOSE: To achieve the improvement in the image quality of hard copies by moving the signal level of image information only when it is detected that there is an emphasis signal and making only the image information corresponding to the emphasis signal portion at the ordinary signal level.  
     CONSTITUTION: In an image information input part 1, the synchronizing separation in the vertical direction is done to obtain the signal 2. In an emphasis information input part 3, the emphasis information is sample-held by the signal 2 and becomes emphasis information 4 and emphasis possession information 5. In an emphasis circuit 6, the image information is attenuated by the AND of the emphasis possession information and the opposite of the emphasis information and no effects other than these are given. The image information obtained in this way is hard- copied from CRT by recording systems 8W11. In this way, the discrimination of the emphasis signal is possible and when the entire part is non-emphasis, the copy is prevented from becoming thin over the entire part and the good quality hard copy may be obtained.

IPC: G02B5/20
Filed: 1988-02-26
Abstract: PURPOSE:To prevent a color filter from delamination at a light shielding film part by forming a resin film having openings, then forming a light shielding film by dyeing the resin film with a black dye, and forming a color filter by an ink jetting process at the opening parts. CONSTITUTION:A light shielding film 6 is formed by dyeing a resin film 5 having opening parts 4. A color filter 8 is prepd. by applying an acrylic transparent thermosetting resin 7 to the whole surface of the light shielding film, baking the product, and then forming a red dye R, green dye G, and blue dye B by an ink jetting process to each part corresponding to the desired opening part 4. The adhesion of an ink to be used as a material for a color filter to a light shielding film is improved by dyeing the light shielding film to a black color with a black dye comprising a synthetic base material for dyeing. Since delamination of a color filter from a light shielding film under severe conditions is prevented by this process, mass productivity and reliability of the process are improved.
