Title: Free running differential device
Inventor: EDA TADASHI
IPC: F16H48/38
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To provide a light-weighed free running differential device capable of certainly changing a driving state by improving the free running differential device without requiring an inner case and a slide gear. SOLUTION: In a device for torque-distributing and transmitting a rotation- driving force of a differential case 1 to right and left side gears 5, 6 disposed on a rotation shaft of the differential case 1 through differential gears 3, 4, a pinion shaft 3 in the differential gears 3, 4 is attachably/detachably mounted on an inner periphery of the differential case 1 and a connection/disconnection of the rotation-driving force from the differential case 1 to the differential gears 3, 4 is carried out. Thereby, since a whole device is made light-weighed without requiring an inner case and a cam ring such as in a conventional device and a space required for the inner case can be occupied by a pinion gear, the pinion gear itself ensures a size to some degree. A sufficient driving force can be transmitted even by light and simple 2-pinion gear type differential gear.

Therefore, the handling property of the photosensitive material is significantly improved in the exposure process in contact with a color mask. Moreover, the color filter has excellent adhesion property between a UV-curing resin and a color matrix formed after development. The monodispersion degree of the matting agent particles is expressed by the radio of the standard deviation to the average particle size calculated as corresponding spheres measured by a 'Coulter(R)' counter. The monodispersion degree of the monodispersed matting agent particles is preferably <=3.3, and more preferably <=3.0, and especially preferably <=2.8.

Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To provide the optical shutter and its manufacturing method which eliminates restrictions on the quantity of incident light and exerts a little influence on optical performance even if a structure generates heat by light irradiation. SOLUTION: The shutter 11 has a metallic thin film 14 patterned on the back of an insulator thin film 13; and the metallic thin film 14 is applied to tensile stress and the insulator thin film 13 is given compressive stress.
