Title: Recording disk
Inventor: SATO MITSUYOSHI
IPC: G11B23/02
Filed: 1989-06-22
Abstract: PURPOSE:To prevent an elastic deformation part from cracking without directly giving stress to the elastic deformation part by providing a pressure releasing groove in an area where a tensile force applied from a disk part to a hub directly works on each elastic deformation part. CONSTITUTION:Plural releasing grooves 7 are formed in the neighborhood of a spindle hole 6, and plural elastic deformation parts 8 are comprised between the spindle hole 6. Also, the pressure releasing grooves 9 are formed at three places at the outer periphery of the hub 3, and they are provided in an inter- auxiliary line area drawn from the approximate center part of the deformation part 8 so as to pass the contact point of the hole 7 and spindle hole 6. Thereby, when the hub 3 shrinks more to a position shown by a virtual line inside than a hub hole 4a shown by a solid line, the tensile force works on the hub 4 from the disk part 4 in a radial direction as shown by arrows. The tensile force working on the inner groove 9 is not transmitted to the inside of the groove 9. Therefore, no tensile force from the disk part 4 is directly applied on the deformation part 8.

IPC: F02M41/14
Filed: 1994-07-12
Abstract: PURPOSE:To provide a distributor type fuel injection pump having high fuel injection efficiency without increasing the dead volume of a force feed system of an injection pump. CONSTITUTION:A fuel passage 28 communicates a suction port 25 and a plunger chamber 21 with each other, and a fuel passage 29 communicates the suction port 25 and a distributing port 26 with each other. The fuel passages 28 and 29 are communicated with each other by an outer peripheral wall of a distributing rotor 13 through the suction port 25. Since a fuel passage in the distributing rotor 13 is only the fuel passages 28 and 29, the dead volume of a force feed system is reduced, and prescribed fuel injection pressure can be held. When the suction port 25 is communicated with a suction passage 15, since fuel can be supplied to the fuel passage 28 and the fuel passage 29 through the suction port 25 from the suction passage 15 by branching off without interfering with each other, a sufficient quantity of fuel can be filled in the plunger chamber 21 without disturbing suction of fuel in the plunger chamber 21 by inertial force of overflowing fuel.

Title: Kettle with lock lid
Inventor: SAKAMOTO TAKUMI
IPC: A47J36/06
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a kettle which has a function of eliminating a smack of resistance to the mounting or removal of a lid during the feeding of water or the like and moreover, of locking a lid with the action of a shape memory alloy with the presence of high temperature water. SOLUTION: A lock member 5 made of a shape memory alloy adapted to retain a lid 3 on the body 1 of a kettle is arranged for the lid 3 and/or the body 1 of the kettle. The lock member 5 is changed into such a shape as to retain the lid 3 on the body 1 of the kettle 1 above a transformation temperature while applying a retaining force but the retaining force is lost below the transformation temperature. Therefore, in nature, the lock member retains the lid on the body 1 of the kettle is released and when the temperature of the water is high, the lid 3 is retained on the body 1 of the kettle, meaning that no suddenly high steam pressure is caused under boiling condition even when stimulated from outside under boiling condition, otherwise forcing the lid 3 to be lifted up.  This prevents the lid 3 from being accidentally opened or dropping even when inclined to pour the high temperature water thereby enhancing the safety of the kettle. On the other hand, when the water temperature is low, the retaining of the lid 3 is released thereby enabling the mounting or removal of the lid 3 without a smack of resistance.
