Title: Tightly fixing device for bobbin
Inventor: SUGIOKA TAKAMI
IPC: B65H54/547
Filed: 1987-06-12
Abstract: PURPOSE:To push out a bobbin smoothly by mounting a resilient member and a tubular member movably onto a bobbin holder body, and releasing the resilient member from compression while maintaining a gap between respective tubular members through a tension member when the bobbin is loosened. CONSTITUTION:When a gripped bobbin 18 is loosened, pressure air is fed through a hole 15b of a bobbin holder 15 into a cylinder chamber 15c so as to compress a Belleville spring 7 through leftward motion of a piston 5 thus moving a cap 4 to the left. Then a tubular member 3A engaged with the flange section 2a of a tension member 2A is pulled to release compression of resilient members 1A-1H with a gap being maintained between tubular members 3 through the tension member 2A. When the bobbin 18 is gripped, supply of pressure air is stopped to move the piston 5 to the right through the Belleville spring 7 so as to move the cap 4 to the right through a rod 9 thus releasing the tension members 2A-2E sequentially. Consequently, the resilient members 1A-1H are sequentially released from compression and enlarged thus gripping the bobbin 18 from the inside. As a result, package can be pushed out smoothly, resulting in improvement of availability and achievement of automation.

Title: Elevator for blind
Inventor: DAIZEN MASAAKI
IPC: E06B9/90
Filed: 1988-06-15
Abstract: PURPOSE:To prevent the damage of a blind by installing a clutch spring capable of being slackened by a fixed or more revolving torque and allowing the idle rotation of a winding shaft between the winding shaft and a fixing section supporting the winding shaft when an excessive force is applied to the winding shaft. CONSTITUTION:When an operating pulley 2 is turned by an operating cord 3, the pulley 2 pushes one end of a first clutch spring 6, and slackens the spring 6. A winding pipe 1 is rotated, and a blind is elevated. When the operation of the cord 3 is suspended and the turning of the pulley 2 is stopped, a cap 4 collides against the other end of the spring 6 and works so as to clamp the spring 6, and the reverse turning of the pipe 1 is prevented and the blind is stopped. When excessive force is applied to the pipe 1 in the direction that the blind is lowered, one end of a second clutch spring 9 collides against a projection 8 and the spring is loosened, and the pipe 1 is slipped and the application of excessive force to other parts for an elevator is prevented.

IPC: F16K7/16
Filed: 1994-06-29
Abstract: PURPOSE:To effectively prevent gas influx from a bent line by furnishing on a valve seat a diaphragm which opens and shuts the communication between an flow-in path and flowout path, and equipping the valve seat with a gas flow hole which puts the flow-in path in communication with the flowout path. CONSTITUTION:In case the present invention is applied to a breeder valve configured with a metal diaphragm valve of manual type, a valve seat 10 is installed over a flow-in path 1a and flowout path 1b in the central part of the body 1 by the use of a seat holder 11, and a diaphragm 12 to open and shut the flow path is installed between over the valve seat 10 and a diaphragm holder 9. A junction ball 13 is accommodated in a communication hole provided in the center of the diaphragm holder 9. In this valve construction, a gas flow hole 10a is formed at the periphery of the valve seat 10 so that the fluid can flow from the flow-in path 1a to the flowout path 1b even when the diaphragm 12 is in close operation, and gas influx from a bent line is prevented in an arrangement where bent line is connected with the flowout path while a purge gas is connected with the flow-in path.

Title: Liquid crystal device
Inventor: WATERS COLIN M
IPC: G02F1/137
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To make the multiplex level of a liquid crystal display device high by applying surface alignment with a progressive molecule twist across a layer in a uniform ramp direction. SOLUTION: The off element of the liquid crystal display device needs be kept at a voltage V1 slightly lower than an on voltage V2. When d/p is changed in a low ramp cell, the value of the voltage V1 remains nearly constant even if the ratio of the thickness (d) of the liquid crystal layer to the pitch (p) of a cholesteric material is increased to >=0.5. The value of the voltage V2, however, increases gradually until d/p attains about 0.75, then rapidly increases. The value of d/p of the low ramp liquid crystal cell thus exists preferably in a range of 0.5 to 0.75. The additional distortion induced by the surface at the value of d/p<0.75 relating to 3π/2 twist decreases the tendency that the cell forms a scattering structure at the voltage immediately above the threshold voltage V1.

Title: Lens driving device
Inventor: AKIMOTO KAZUO
IPC: G02B7/08
Filed: 1994-06-29
Abstract: PURPOSE:To obtain a lens driving mechanism in which voltage impressed on an oscillating motor is set low, whose current consumption is low as a camera and whose reliability on operation is high by preventing a lens setting ring from being turned by a ratchet and a locking lever against the energizing of a spring in an initial state. CONSTITUTION:The engagement of a pair of catches 7a and 7b of an anchor 7 with the pawl 6b of the ratchet 6 prevents the lens setting ring 3 from being turned against the energizing of the spring 4 when optional voltage is impressed on the oscillating motor 8, and it allows the turning of the lens setting member 3 by the energizing of the spring 4 when the voltage is not impressed on the motor 8. The motor 8 is energized so that the rotation of the ring 3 by the energizing of the spring 4 may be allowed stepwise by alternately engaging the catches 7a and 7b of the anchor 7 with the pawl 6b of the ratchet 6 after releasing the engagement of the ratchet 6 with a locking lever 9 by the rotation of a driving ring 11.
