Title: Measuring method for height of flexible film weir
Inventor: INOUE NOBUO
IPC: G01F1/00
Filed: 1981-08-11
Abstract: PURPOSE:To perform practical, easy and accurate measurement by finding the depth of an overflow from the hydraulic pressure at an overflow part near a  film weir peak point, and regarding the difference between an upper stream-side water level and the depth of the overflow as the height of a weir. CONSTITUTION:A belt-like rubber sheet is folded in two and its suerposed edges 3 are stuck on a riverbed surface 7 to constitute a airtight flexible bag as a rubber weir 2, whose height of the weir is adjusted by its internal air pressure. A band 11 made of rubber is arranged in contact from the edge 3 to a folded projection part F. The weir has a peak T invariably at prescribed distance from the projection part without reference to variation in the shape of the weir, so a hydraulic pressure sensor 14 is embedded therein to lead out a pressure signal through wiring 15. Then, the depth (h) of an overflow is found from the hydraulic pressure P, atmospheric pressure P0, and specific gravity gamma of water. Further, an upper stream-side water level H is obtained by a water gauge to find the height of the weir HT from HT=H-h.

Title: Rotational motion tool for ankle
Inventor: SAEGUSA TSUTOMU
IPC: A63B22/16
Filed: 1995-04-14
Abstract: PURPOSE: To generate a very high effect of training and strengthening an ankle and knee and also strengthening the muscular force of the feet and waist by installing a ball caster and a screw foot in the center of discs confronting each other up and down, attaching a slip stopper to the oversurface of the upper disc, and consolidating them in a single piece. CONSTITUTION: A ball caster 2 and a screw foot 3 are installed in the center of discs 1, 1' confronting each other up and down, and these are consolidated in a single piece, and a slip stopper 4 is attached to the oversurface of the disc 1. When ankle training is made with this tool, feet 5 are placed on the disc 1 in such a way that they are open to a certain extent, and the body weight is shifted to any side, which causes the disc 1 to incline in the condition that its point in the down position touches the lower disc 1'. If the body weight is further moved, the inclined surface shifts to that side, and continued performance of this motion generates a circular motion 6 of the inclined surface round a fulcrum through the action of the ball caster 2.  Accordingly the ankles 5 make a circular motion automatically while the body weight is loaded unchangedly in compliance with the variation of the inclined surface.

Title: Method of moderately controlling fuel injection quantity in diesel engine
Inventor: NAGASE MASAOMI
IPC: F02D41/12
Filed: 1983-07-11
Abstract: PURPOSE:To effectually reduce the shock of acceleration and deceleration in a wide range of operation and prevent white smoke from being made, by gradually nearing the quantity of injected fuel or the degree of opening of an accelerator to an aimed value by every allowable alteration quantity in the acceleration or deceleration. CONSTITUTION:It is detected by sensors whether the temperature of cooling water of engine, the speed of a vehicle, the shifted position of a manual transmission and the revolution speed of the engine are higher or lower than prescribed values. The maximum of allowable increases alpha1, alpha2, alpha3, alpha4, which are determined when said quantities are lower than the prescribed values, and the maximum of allowable decreases beta1, beta2, beta3, beta4, which are determined when said quantities are higher than the prescribed values, are used as a final allowable increase alpha and a final allowable decrease beta. An aimed value Qi for the quantity of injected fuel is calculated depending on the revolution speed of the engine and the degree of opening of the accelerator. In the acceleration of the engine, the quantity of injected fuel is gradually augmented to the aimed value Qi by every allowable increase alpha. In the deceleration of the engine, the quantity of inected fuel is gradually reduced to the aimed value Qi by every allowable decreases beta. The quantity of injected fuel is thus moderately controlled. This results in reducing the shock of the acceleration and deceleration and preventing white smoke from being made by the engine furnished with an intake orifice.
