IPC: G02B5/20
Filed: 1989-03-20
Abstract: PURPOSE:To obtain a color filter with a light shielding pattern having superior light shielding property by using diaminoanthraquinone-contg. polyimide as black resin. CONSTITUTION:A light shielding pattern 5 is formed among the color patterns 2 of a color filter by applying and hardening paste prepd. by mixing diaminoanthraquinone-contg. polyamic acid having structural units represented by general formulae I, II with a light absorber. In the formulae, each of R1-R4 is H, halogen, hydroxyl, cyano, nitro, alkyl, alkoxy, phenoxy or alkoxyphenoxy, Ar is a tetravalent org. group and Z is a divalent org. group. Since the polyamic acid is black, the light shielding pattern 5 having superior light shielding property is formed by using the polyamic acid mixed with the light absorber and a color filter with the light shielding pattern having superior light shielding property simply is obtd.

Title: Torque limiter device
Inventor: HIROSE YOSHIHIKO
IPC: F16H35/10
Filed: 1986-03-25
Abstract: PURPOSE:To obtain a torque limiter device which performs stable action even under whatever environmental condition the device is placed, by constituting a rotation transmitting member, loosely fitted to a shaft, of a moisture absorptive swelling resin. CONSTITUTION:If a driving shaft 11 rotates, a driven shaft 7 rotates through a torque limiter main unit 3 via spur gears 1, 10. A spur gear 1 of a rotation transmitting member is constituted of moisture absorptive swelling resin of nylon 6, nylon 66, etc., and if an environmental condition changes high increasing humidity, friction members 2, to which water in the air is absorbed, decrease the coefficient of friction with the spur gear 1. However, since the spur gear 1, prepared by the moisture absorptive swelling resin, absorbs the water to increase the volume and press a spring 5 by the increase of the volume, a load of the spring increases being applied to a pressurizing member 4, while the friction members 2 are pressed to side surfaces of the spur gear 1 by storing force as compared with that before moisture is absorbed, and friction force is increased by increasing a contact area with the friction member 2.

Title: Color toner replenishing device
Inventor: TAKASHIMA HIROSHI
IPC: G03G15/08
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a color toner replenishing device capable of performing the stable controlling operation, without being affected by the property of a developer, etc. SOLUTION: This device decides a density of the color toner by determining a difference between the output (maximum value) when performing write-in by the maximum laser beam in an monotonously increasing area of an optical sensor 9 with regular reflection system, and the minimum value of the whole output property of the optical sensor 9. As a result correction of the developing bias of the patch pattern for detecting the toner adherence quantity, or the correction of target value of the toner replenishment is performed, neither of which had been conventionally performed. The value of the above difference is approximately proportionated to the toner density, but not influenced by such as the property of the developer.

Title: Blooming mill roll
Inventor: OKI MASAMI
IPC: B21B1/06
Filed: 1978-06-01
Abstract: PURPOSE:In a roll hole-type mold, the diameters at the grooved bottom on roll surface are made equal each other, thereby to reduce one side elongation and enhance yield output. CONSTITUTION:The upper 1 and lower 2 horizontal rolls constitute reduction-use hole-type molds 3, 4, 5, 6 and the diameters of the roll at the grooved bottom are all made to the same dimension (D1=D2=D3=D4). The lower roll is adjusted so that pick up amount of the lower roll groove bottom surface and table top surface is half the maximum reduction. This reduces the initial slope angle to zero or nearly zero. When rolling, steel ingot 8 is transferred by the table roller 7 and enters the first hole-type mold 3. Because the pick up amount of the hole-type mold 3 groove bottom surface and the table roll top surface is set to about half the maximum reduction, the initial slope becomes small, resulting in small shearing deformation and reduced one side elongation at initial rolling. Each hole-type mold causes sequentially small slope under reduction, decreasing one-side elongatin.
