Title: Water wheel controlling device
Inventor: SUGISAKA HIROSHI
IPC: F03B15/08
Filed: 1984-04-18
Abstract: PURPOSE:To enable the stable start and uniform speed of a water wheel even in a low head region by setting a speed setting device at a higher position than the rated speed of rotation before starting, and carrying out a speed uniforming operation by means of a load limiter. CONSTITUTION:A speed setting device 11 is elevated before starting a water wheel, with its set value 65F being set in a position a certain value higher than the rated speed of rotation. The water wheel is gently started by means of a load limiter, and a speed uniforming device 8 is operated when the speed of roration reaches B. Since the speed set value 65F is set higher than the rate speed of rotation, the guide-vane opening 74 is always controlled by an opening limiter. Therefore, since the closing operation for the guide vane, due to the signal of an opening target 65, is not carried out midway while starting, change in the flow rate of the water wheel is gentle, enabling stable starting.

Abstract: PURPOSE:To enable to operate a water turbine in a stable manner even at the time of transient operation, by improving vibration characteristics of the turbine through employment of such an arrangement that the lower end face of a guide vane and a portion of a lower cover for the water turbine are fitted to each other. CONSTITUTION:A guide vane 1 is formed integrally with an upper stem 2 and a spherical projection 10 is formed at a portion of the lower end face of the guide vane 1. Further, a spherical recess 11 is formed in a lower cover 9 for a water turbine in the manner that the projection 10 is fitted in the recess 11. Here, the centers of the spherical surfaces of the projection 10 and recess 11 are located on the axis C around which the guide vane stem 2 is turned. With such an arrangement, any restriction to rotation of the guide vane is imposed, during normal operation of the water turbine, by the portion where the projection 10 and the recess 11 are fitted. On the other hand, when a vane deforming force is acted by abnormal vibration or excessive external force, movement of the vane is restricted by the fitting of the projection 10 and the recess 11, so that the water turbine can be operated always in a stable manner.

Title: Ic socket and ic measuring device using the same
Inventor: MASAGAKI TOSHIHIRO
IPC: H01L21/66
Filed: 1988-03-30
Abstract: PURPOSE:To decrease inductive impedance induced in conductive pieces so as to enable stable and accurate measurement even if it is used for measurement of ICs used for high frequency signals by bending, by below the angle of 90 deg., the conductive pieces which connect leads of an IC to be measured with a copper foil of a printed board. CONSTITUTION:If a measurement signal from a measuring device is applied to a specified lead 13 of an IC 12 and the output signal is taken out through another lead 13, a conductive piece 9 and a copper foil 11, the measurement of the IC 12 can be performed. At this time, the conductive piece 9 is bent by below the angle of 90 deg. and in particular, a part located inside a socket main body 8 being the main part of the conductive piece 9 is only bent by only about 30 deg.. For this reason, inductive impedance induced in this conductive piece 9 becomes remarkably small. Also, the overall length of the conductive piece 9 is sufficient at about half the conventional one, and this matter also serves to decrease the inductive impedance. The loss of signal components by the conductive piece 9 can be ignored and accurate measurement can be performed.
