Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To apply a uniform flow, low in turbulence, on an impeller and to provide a high pump efficiency and cavitation performance by a method wherein the side wall of a suction flow passage is formed in a shape wherein the side wall is inclined such that the radius of the side spaced away from an impeller suction port is decreased to a value lower than that of the side situated nearer the impeller suction port. SOLUTION: The suction passage of a multistage pump comprises a suction flow passage 1 constituted integrally with a barrel casing; and a suction flow passage 2 arranged at an inner casing part. The shape of the flow passage side wall 2c of a suction flow passage 2 is formed such that the radius of the side spaced far from an impeller suction port is decreased to a value on the side nearer the impeller suction port. Further, a protrusion 2d is arranged at the ends, situated downstream from the side walls of the suction flow passages 1 and 2, in a state to be deviated in the rotation direction of a pump from the central line of a suction flow passage running the axis of the pump.  A flow straightening plate 2f is arranged in a suction flow passage, situated upper stream from an outlet, and in a position deviated in a manner to divide a flow passage such that the sectional area of a flow passage on the side 2a, where a pump rotation direction coincides with a flow direction, is high and the sectional area of the flow passage of the reverse side 2b is low.

Title: Lens holding member
Inventor: OTA SHIRO
IPC: G02B7/02
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent an optical lens from falling off. SOLUTION: Two annular grooves 11 having V-shaped cross section are formed on the adhesive surface 9 of a lens chamber 7 in a lens holder 1, and a trough part 13 of the groove 11 is a recessed part. When adhesive is injected in a gap (21) between the surface 9 and the optical lens 5, a part of the adhesive 23 enters the trough part 13 of the groove 11 and is hardened when a specified time elapses. Since the thermal expansion amount of the lens holder 1 due to the rise of outside air temperature is large in the case of using the lens barrel under a burning sun, the gap (21) between the surface 9 and the lens 5 is extended. In such a case, tensile stress acts on the adhesive 23, but is dispersed and absorbed by the elasticity of the adhesive 23 at a wedged part 27 where the adhesive entering the trough part 13 of the groove 11 is hardened.  Even when the adhesive 23 is peeled from the surface 9, the wedged part 27 is engaged with the groove 11, so that the lens 5 is prevented from falling off.

Accordingly, the video signals of the first field and the second field are magnetically recorded throughout the angle exceeding 360 deg. at the central angle on the annular track. Namely, a recording completion part is overlapped on a recording start part. Since the recording completion part is overlapped on the recording start part, there is no fear that the defective part of the video signal is produced in the track and accordingly, the defective part is not produced in the reproducing RF signal of the magnetically recorded still picture.
