  • Patent number: 11953308
    Abstract: A light emitting element array includes: a light emitting element group that includes plural light emitting elements; and plural lenses that are provided, corresponding to the plural light emitting elements, on a light emitting surface side of the plural light emitting elements, and that deflects light emitted from the plural light emitting elements according to a positional relation with the plural light emitting elements. Distances between central axes of light emission of the plural light emitting elements and central axes of the plural lenses corresponding to the plural light emitting elements increase from a center side of the light emitting element group toward an end side of the light emitting element group, and a degree of change in the distances decreases from the center side of the light emitting element group toward the end side of the light emitting element group.

  • Publication number: 20060273272
    Abstract: A valve device is provided, by which a reverse flow can be avoided without being restricted by pipe arrangement and without bending a primary piping, thereby preventing a defective operation due to a dynamic pressure from occurring. An inlet side inner passage includes a bent part (formed with an inlet side lateral inner passage 21 and the inlet side longitudinal inner passage 22) in a valve housing 11, that is, the inner passage formed in the valve housing 11 takes charge of such a bent part required in a primary piping to avoid a reverse flow.

  • Patent number: 6076553
    Abstract: In a rotary flow-path exchanging valve, the magnetic force generated in a pair of main magnetic pole pieces (66) by energization of an electromagnetic solenoid is acted on a multi-pole magnet (71) of a main valve element accommodated within a valve housing (1) so that the main valve element (3) is rotated to exchange a flow-path. The multi-pole magnet (71) is made of a plastic magnet of plastic material mixed with magnetic powder. The main valve element (3) and multi-pole magnet (71) are integrally formed by multiple molding. A pair of main magnetic pole pieces (66) magnetically connected to one polarity of the electromagnetic solenoid (11) are arranged. A pair of auxiliary magnetic pole pieces (70) connected to the other polarity of the electromagnetic solenoid (11) are arranged at positions out of phase from the magnetic pole pieces by 90.degree..

  • Patent number: 5937902
    Abstract: In a rotary flow-path exchanging valve, a high pressure side communicating groove 37 is provided to communicate a first exchanging port 23 and a second exchanging port 27 of a valve seat plate 5 with a high pressure side communicating port selectively. A part of a joint pipe 17 to be connected to the high pressure side port 19 is protruded into the high pressure side communicating groove 27. The protruding part constitutes a stopper pipe 20 for limiting the rotatable range of a valve element 1. In installing the stopper pipe 20, it is connected and secured to the high pressure side port 19 of the valve seat plate 5, and thereafter is hardened by plastic deformation processing. Thus, when the stopper pipe is heated by soldering for its securing to the valve seat 5, the necessary strength thereof can be maintained.
