Title: Manufacture of plastic lens
Inventor: YATSUDA NORIO
IPC: B29D11/00
Filed: 1987-12-25
Abstract: PURPOSE:To manufacture a plastic lens having high quality in a high cycle by dividing the lens into two pieces, forming them from a center gate, and binding them by refilling resin. CONSTITUTION:In order to divide a lens into two lens pieces each having one side plane and 2mm of central thickness, cam grooves to be engaged with cams 9, 10, 11, 12 of elements 5, 6 and sleeves 7, 8 are formed on guide plates 13, 14, 15, 16. The temperature of a center gate jig 1 is held constantly at 150 deg.C by an inner heater 3, and the elements 5, 6 and the sleeves 7, 8 are held constantly at 120 deg.C by the heater. The temperature of a nozzle 21 is set to 240 deg.C, resin is filled for 5sec, and it is held in this state for 1min. In case of refilling the resin to bind the divided lens pieces, a nozzle 25 held at 270 deg.C is completed by disposing the elements 5, 6 and the sleeves 7, 8, then moving a molding machine, touching the nozzle 25 to nozzle retainers 23, 24 and filling it. A molding cycle includes 65sec of a filling step, 15sec of a refilling step, and approx. 10sec of moving and removing steps, thereby molding it in a high cycle of 2min or less.

Title: Operation method for tension leveler
Inventor: KANDA TETSUHIKO
IPC: B21D1/05
Filed: 1992-12-07
Abstract: PURPOSE:To completely prevent trouble such as breakage of a work roll by decreasing pressurizing force when a strip welding point is passed through a tension leveler without vertically moving a roll chock. CONSTITUTION:For instance, when an inlet side bridle is reached with the welding point 2, a lower side pressure reducing valve 11 is selected and when an outlet side bridle is passed with the welding point 2, a higher side pressure reducing valve 10 is automatically returned. That is, pressurizing force of a lower roll chock is decreased when the welding point 2 is passed and impact force generated at that time is mitigated. A trouble such as breakage of the work roll which was often generated during quick opening is completely prevented and production efficiency is remarkably improved since the welding point 2 of the strip 1 is passed without vertically moving the roll chock 7 by providing a pressurizing force decreasing means on a device by which the roll chock 7 of the tension leveler is pressed on a housing 3 to be contacted.

Title: 2 cycle internal combustion engine
Inventor: SASAKI KAZUNORI
IPC: F02B33/30
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent non-evaporative raw fuel from being led to flow into the inner circumferential surface of a crank chamber regardless of the change of the attitude of an engine, by projecting a rib-shaped projection part so as to be placed in the inside of an intake opening, to a position on the free end part side of a reed valve in the downstream side end surface of an insulator for insulating heat, which is attached to a crank case. SOLUTION: In the case that a 2 cycle internal combustion engine is mounted in a chain saw, when operation is executed by downwardly directing the front part of the chain, saw, non-evaporative raw fuel stuck on the inner circumferential surface 22A and so on of a crank chamber gets over weirs 23 and is accumulated in a corner step difference part P. After that, when the front part of the chain saw is upwardly directed, a part of accumulated non-evaporative raw fuel tries to flow into the inner circumferential surface 22A, however, a part thereof is dammed out by a rib-shaped projection part 45 projected to a part on the free end part 36b side of a reed valve 35. Then, an air-fuel mixture from a carburetor 30 is collided with the rib-shaped projection part 45 when the reed valve 35 is started to be opened, therefore accumulated non-evaporative raw fuel is dispersed into the air-fuel mixture so as to accelerate the evaporation of the raw fuel.

Title: Method for packaging food for preventing insect damage
Inventor: KUROKI JUNICHI
IPC: B65D81/28
Filed: 1989-12-19
Abstract: PURPOSE:To securely prevent insect damage after packaging food by a method wherein after food is packaged by using a wrapping material having barrier property against moth-proofing agent, it is packaged by using a cardboard box containing moth-proofing agent. CONSTITUTION:As a wrapping material having a barrier property, a metallic foil such as an aluminum foil, a gold foil and a silver foil or a plastic film with aluminum evaporated can be used while synthetic pyrethroid, natural or synthetic pyrethrin, low toxic organic phosphorus insecticide, insect repellent, etc. can be used as moth-proofing agent. When a cardboard is to be coated with the moth-proofing agent, the agent is used as it is or the agent is coated with a vehicle or additive added to have the agent inked, while when the moth- proofing agent is blended into adhesive of the cardboard, natural adhesive such as starch or dextrin, synthetic resin agent comprising thermoplastic resin or thermosetting resin, or synthetic rubber adhesive comprising SBR, butyl rubber, etc. is used. As a result, even if the moth-proofing agent is gasified, it is not in contact with the food thereby protecting the food from insect damage.

Title: Ink jet recording device
Inventor: MATSUI NAOKI
IPC: B41J2/055
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent interlocking displacement caused by deformation of piezoelectric members by forming rigid protruded streaks on the back faces of the piezoelectric members which displace an ink in an ink channel. SOLUTION: An electrode 26b on a rear face of each of piezoelectric members 25a and 25b is grounded. Each of them applies negative voltage to an electrode 26a at an ink channel-side. Then, in the first and second piezoelectric bodies 25a and 25b electric fields are formed in directions of arrows E1 and E2 and deformed into forms shown by broken lines 42a and 42b. At this time, respective rear faces of the piezoelectric bodies 25a and 25b are made to be protruded streaks 23, which do not give influence of the deformation to an ink channel 16. As a result, the volume of the ink channel 16 rapidly reduces and an ink which is filling the ink channel 16 is pressed and discharged from a nozzle hole. Next, when the application of voltage is completed, both the first and second piezoelectric bodies 25a and 25b return to original states shown by solid lines 41a and 41b.  At this time, the pressure is reduced by expansion of the volume in the ink channel 16 and an ink of the discharged quantity is supplied.
