Title: Self priming pump
Inventor: INOUE SEIJI
IPC: F04B23/02
Filed: 1982-04-22
Abstract: PURPOSE:To certainly suppress excessive supply of air by means of an automatic air supplying apparatus by freely inserting the excessive air supply suppressing pipe onto the outer periphery of the lower edge of a water supply pipe and positioning the cut edge of the lower part of the excessive air supply suppressing pipe higher than the height of the opening of a discharge pipe. CONSTITUTION:An excessive air supply suppressing pipe 18 is freely fitted onto the outer periphery of the lower edge of a water supply pipe 17, and the undersurface of an outer collar 18a at the upper edge is attached onto the upper surface of a pressure tank 1 through a gasket 19, and the cut edge 18b of the lower part is positioned higher than the height of the opening of a discharge pipe 15. When the water in an upper pump casing 5 is frozen, the water supply pipe 17 is shifted downward by the expansion pressure due to freezing, and then the expansion pressure is reduced, so breakage of the upper pump casing 5 can be prevented previously. Because only the water supply pipe 17 is shifted downward by the expansion pressure, and the excessive air supply suppressing pipe 18 is not shifted, the cut edge 18b of the excessive air supply suppressing pipe 18 is not positioned lower than the height of the opening of the discharge pipe 15, and excessive air supply can be suppressed certainly.

Abstract: PURPOSE:To make it possible to measure a lens having a small measuring field such as a progressive multi-focus lens or a contact lens, by varying the diameter of ring-shaped luminous flux using movable deflection member and making the measuring field alterable. CONSTITUTION:A conical prism (deflection member) 11 is arranged between a mask plate 12 forming ring-shaped luminous flux and a light source 10 and constituted so as to be movable to the optical axis direction. When the conical prism 11 is moved to the direction shown by an arrow 18, the deflection position of the luminous flux from the light source 10 changes and, therefore, the angle of inclination of the luminous flux passing through the opening 12a of the mask plate 12 with respect to the optical axis O and the diameter of the ring-shaped luminous flux passing through a lens L to be inspected changes and a measuring field also changes. Therefore, plural kinds of lenses different in the measuring field can be measured by the same lens meter.

IPC: G08G1/16
Filed: 1993-03-05
Abstract: PURPOSE:To concretely and effectively designate a safety traveling speed in an unfamiliar place by storing a speed limit in which a general vehicle can safely travel at each predetermined ground point corresponding to a road map, and sequentially designating the limit at each position of an own vehicle during traveling. CONSTITUTION:A vehicle information storage unit 5 stores traveling performance information of its vehicle such as fixed information in which how centrifugal force (so-called lateral g) can be supported by a frictional force of tires of the vehicle or rewritable information. A speed limit calculator 6 calculates a speed limit at each ground point from the performance information, sends it to an indicator 7 and indicates an upper speed limit to be traveled in safety. For example, when the vehicle arrives at a curve, the lateral g of the vehicle to a vehicle speed is calculated by a curvature of a road obtained from a road state, an upper speed limit is obtained from the lateral g in which wheels can endure, and designations of a passing speed and deceleration are displayed on the indicator 7.

Abstract: PURPOSE:To facilitate both optical adjustment and assembling and to obtain a compact optical system by setting approximately in parallel the optical axis of parallel beams converted by a condenser lens and the optical axis of a lens which focuses one of two split reflected beams with use of prisms set to an incident optical path and an inverted optical path respectively. CONSTITUTION:The beam diameter is increased by an enlarging prism 12 only in the direction parallel to the junction surface of a semiconductor laser, and the laser light is turned approximately into a circle. Then the light beam is totally reflected and then reflected by a polarized beam splitter 4 to pass through a lambda/4 plate 7. Then an approximately circular and equidirectional microspot light is obtained on a disk 6 through a diaphragm lens 5. While the reflected light sent from the disk 6 transmits through a polarized beam splitter 7 and is led to a split prism 13 which performs both focus and tracking controls. About half of the reflected light from the disk 6 is reflected totally in the reflected light path by a reflecting surface (d). While the other half of the reflected light is stopped down by a semi-convex lens 14 and irradiated to a photodetector 10 set at the image forming position. Then a focus error signal is obtained from the output difference between photodetectors 10a and 10b.
