Title: Multi-component blade for gas turbine
Inventor: FITZGERALD JOHN JAMES
IPC: F01D5/28
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To improve strength against damage caused by bird suction and blade slip-off by forming an airfoil part of a gas turbine blade of a metal part and an elastic part, and extending the metal part with first mass density radially from a blade root to a blade tip while jointing the elastic part with second mass density to the metal part. SOLUTION: A gas turbine blade 10 of a gas turbine engine for an aircraft has an airfoil part 14 with a shank part integrally formed at a lower part, and the airfoil part 14 has a blade root and a blade tip. The airfoil part 14 has a metal part 28 with first mass density, and the metal part 28 is provided in such a way as to be radially extended from the blade root almost to the blade tip. The airfoil part 14 also has at least one panel part 38 jointed to the metal part 28 and having second mass density formed of rigid compound material containing elastic material such as elastomer. This panel part 38 is formed of first to third panel parts 38'-38''' spaced from one another, and a rib 40 integrally formed at the metal part 28 is arranged between the adjacent panel parts.

Title: Injection molding method for foamed plastic molding
Inventor: ONO TSUKASA
IPC: B29C33/40
Filed: 1990-05-15
Abstract: PURPOSE:To improve foam magnification of a foamed plastic molding by making use of an ordinary injection molding machine, by a method wherein a point of time of release of a nozzle at the tip of the injection molding machine is delayed from a point of time of starting of a forward movement of a screw or a plunger. CONSTITUTION:A matter, for example, obtained by mixsing up 100 pts. wt. polypropylene (melt index=30) ad 0.6 pts. wt. azodicarbonamide as a foaming agent with each other is made raw materials. For example, a measure having product weight of about 1.3kg is molded by an ordinary inline screw-type injection molding machine whose clamping force is 515 tones, injection capacity is 3140 cm<3> and injection ratio is 650 cm<3>/sec. In this instance, when molding is performed by allowing a lag time by release of a nozzle from the starting of a forward movement of a screw, foam magnification of a foamed plastic molded body can be improved. When the log time is made, for example, 0.3-1 sec., a favorable product having the foam magnification of 1.5 in general is obtained.

Title: Crawler track link member
Inventor: SPIES KLAUS
IPC: B62D55/275
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the initial crack and breakage of the slide part of the base plate of a crawler track.

Title: No-contact point ignition device for engine
Inventor: SOTOZAKI MORIYOSHI
IPC: F02P9/00
Filed: 1979-09-28
Abstract: PURPOSE:To efficiently prevent the excess revolution of an engine and at the same time, simplify the constitution by by-passing a charging by condenser under the normal direction voltage of AC generator when the rotary speed of an engine has exceeded a prearranged level. CONSTITUTION:A condenser 7 is charged under a normal direction voltage of AC generator 1 driven synchronized to an engine and the charge of condenser 7 is discharged suddenly into the primary coil 14 of ignition coil 13 by turning on SCR8 under reverse direction voltage on AC generator 1. Then a high voltage is generated on the secondary coil 15 to ignite an engine. Time constant circuit 9 designed to keep SCR8 turned on for a prearranged period of time after its switch-on, is connected between the gate and cathode of SCR8. After this procedure, when the number of revolutions of an engine has exceeded a prearranged level, the charging of condenser 7 under the normal direction voltage of AC generator 1 is by-passed.

Title: Ion effect type engine in diesel-engine
Inventor: TAKAHASHI HIDEYORI
IPC: F02B3/06
Filed: 1985-06-10
Abstract: PURPOSE:To make it possible to effect complete combustion to improve exhaust gas, by providing an electrode in a passage between an air cleaner and an intake-air manifold to charge intake-air at a high voltage so that both O2 and N2 are ionized negatively. CONSTITUTION:High frequency voltage generated by an oscillator 1 and an amplifier 2 is boosted up by an ignition coil 3 and is applied at the negative side to a mesh-type electrode 5 disposed in the passage between an air cleaner 4 and an intake-air manifold 7 and at the positive side to a metal cylinder 11 in a fuel pump 10. With this arrangement, intake-air is ionized with a negative voltage so the N2 is turned into N<--> and N<-> which are hard to combine, while O2 is turned into O2<--> and O<-> which are easy to combine. Meanwhile, fuel from a fuel pipe 13 and a fuel hose 12 is charged positively to become easy to combine with O2 so that the fuel is completely burnt, thereby it is possible to reduce the discharge amount of CO and HC and the amount of generation of NOX.

Title: Recovering device of waste toner
Inventor: MIYAKE HIROYUKI
IPC: G03G21/10
Filed: 1984-06-21
Abstract: PURPOSE:To keep the part where a pipe for toner discharge is fitted in a recovery container invariably tight regardless of vibrations and to prevent toner from scattering by arranging a shutter which has a blocking member made of a flexible elastic material atop of the pipe which discharges waster toner from the device. CONSTITUTION:The toner recovery container 16 is mounted at a specific position from outside a machine and the pipe 3 is inserted into the opening 17a of a toner receiving part 17. Then, the peripheral edge part of the opening 17a abuts on the blocking member 1a of the shutter 1, which is further moved back against a spring 5. Toner to be discharged is conveyed by a screw conveyor and falls in the recovery container 16 through the opening 3b. At this time, the recovery container 16 is vibrated and the toner receiving part 17 is also displaced from the pipe 3, but the gap part between the opening 17a and the outer periphery of the pipe 3 is blocked invariably with the blocking member made of the flexible elastic material adaptively to the moving deformation of the gap part due to the variations, so on toner scatters out of the container.
