Title: Clutch operation mechanism for car
Inventor: KIKUCHI YASUSHI
IPC: F16D25/08
Filed: 1982-06-25
Abstract: PURPOSE:To secure the stroke in the half-clutch area together with the sufficient margin for cutting by moving the connecting point between an arm and a push rod of a master cylinder device by a link. CONSTITUTION:When a clutch pedal is stepped on, arm 9 together with a shaft 6 are turned clockwise. At this time, a link 5 is also turned round a support shaft 4 clockwise to move a connection pin 7 along a long hole 8. Thereby, the length of the arm 9 to push down the push rod 10 gradually gets longer to increase the work volume of the push rod 10 gradually and accordingly. As the lever ratio of the arm 9 is reduced, the margin for cutting is rapidly increased to secure the sufficient margin.

Title: Base for photographic printing paper
Inventor: OMOTANI TSUNEHISA
IPC: G03C1/79
Filed: 1988-05-07
Abstract: PURPOSE:To obtain the base which has high resistance to water and scratching and has excellent curling resistant and hole punching properties by forming the front side coating layer of the base into a two-layered structure consisting of both half layers on the inner and outer layers by using a polyolefin resin. CONSTITUTION:The base 1 consists of a sheet-like substrate 2, the front side coating layer 3 and the rear side coating layer 4. The layer 3 consists of the outer half layer 3a and inner half layer 3b consisting of the resin compsn. different from each other. The average density of the polyolefin resin used in the half layers 3a, 3b of the layer 3 is confined to <=0.940 and is set lower than the density of the polyolefin resin contained in the layer 4. The density of the half layer 3a is set higher than the density of the half layer 3b. The curl balance of the base 1 is hardly obtainable and the hole punching property is degraded if the density of the half layer 3a exceeds 0.945. Flaws are likely to be generated in the layer 3 surface when the density is below 0.930. The resistance to scratching and water is thereby enhanced and the curling resistant and hole punching properties are improved.
