Title: Pickup device and information recording/reproducing device having its pickup device
Inventor: MAEDA TAKANORI
IPC: G11B7/1353
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To reproduce information in which crosstalk is restrained without erasing information already recorded in an information recording medium or the like. SOLUTION: A light source 1 emitting a first light and a second light whose polarizing directions are orthogonal each other is provided, and an optical disk 7 is irradiated with light beams generated by converging these light by an objective lens 6 through a grating 2 which merely transmits the first light and diffracts the second light at prescribed diffraction efficiency. When information is recorded, the second light is set in the lights out state or in the low power state, and information is recorded with light beams generated by the first light. When information is reproduced, both first and second light are emitted information is reproduced with light beams generated by the first light and also an adjacent track is irradiated with light beams generated based on diffracted light generated by the second light being diffracted.  Thus, when information is reproduced, the adjacent track is irradiated with low power light beams, and information for removing a crosstalk component is obtained without erasing information or the like.

Title: Gaseous fuel injection nozzle
Inventor: BABA FUMITOMO
IPC: F02M61/12
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To hold a clearance with prescribed accuracy by fixing a cylindrical body which is formed of a solid material and whose frictional resistance is smaller than frictional resistance formed between a nozzle main body and a valve element, on a sliding surface of the nozzle main body and the valve element, and slidably arranging the valve element on a nozzle main body through the cylindrical body. SOLUTION: A needle 5 is slidably inserted into a valve sliding hole 3a through cylindrical bodies 10, 11. The cylindrical bodies 10, 11 are fixed to inner circumferential surfaces of the large diameter part 3b and a small diameter hole part 3c of the valve sliding hole 3a. A needle 5 is slidably supported by the cylindrical bodies 10, 11. The cylindrical bodies 10, 11 are formed of a slid material. In the cylindrical bodies 10, 11, a material is employed whose frictional resistance between an inner circumferential surface and an outer peripheral surface of the needle 5 is smaller than a frictional resistance in the case where the inner circumferential surfaces of the large diameter hole part 3b and the small diameter hole part 3c and an outer peripheral surface of the needle 5 are brought into directly contact with each other.  It is thus possible to prevent early wasting of a sliding surface between the nozzle main body and the valve element and seizing, and it is also possible to hold clearance accuracy with a desired accuracy.

Abstract: PROBLEM TO BE SOLVED: To load both the ears with nearly all of the weight and to reduce the weight on the face to lightness like touching by connecting a frame having a thread-cut tip and an anchor having an internal screw and adjusting right/left length, and connecting a weight by an outside hinge. SOLUTION: The frame 1 has its tip cut into a screw and the anchor 2 has the internal thread. The frame 1 and anchor 2 are connected to adjust the right/left length and then fixed with an adhesive. The weight 4 is connected to a stopper by a chain or the external hinge 3. In this case, the hinge 3 which is provided outside can fold the weight 4 outward by 180 deg.. Thus, the frame 1 and anchor 2 are connected, the right/left length is adjusted, and the weight 4 is also connected by the external hinge 3 to nearly double the weight of the spectacles, but the front and rear across both the ears are balanced. Therefore, nearly all the weight is loaded on both the ears and the weight on the face is reduced almost to lightness of touching. Even when the chain is connected, the same effect is obtained.
