Title: Toroidal type continuously variable transmission
Inventor: UEDA KAZUHIKO
IPC: F02B3/06
Filed: 1993-11-05
Abstract: PURPOSE:To prevent the efficiency of power transmission from being lowered due to dipping of a disc rotor into return oil. CONSTITUTION:In a toroidal type continuously variable transmission Z in which a valve body 35 is located at a position below toroidal type continuously variable transmission mechanisms 4, 5 incorporating input and output discs 11, 12, oil return holes 41 to 43 through which oil is returned from the toroidal type continuously variable transmission mechanisms 4, 5 into an oil pan 2, are formed in the valve body 35 at positions corresponding to maximum diameter parts 11a, 12 of the discs 11, 12. With this arrangement, even though a large quantity of oil is pooled on the upper surface of the valve body 35, the oil can flow down through the oil return holes 41 to 43 so that the level of the pooled oil is lowered at the positions of the holes 41 to 43, and accordingly, the maximum diameter parts 11a, 12a of a Diesel-engine are prevented from being dipped in the oil. As a result, no power loss caused by the resistance of agitation of dipping oil occurs, thereby it is possible to obtain a high degree of power transmission.

A short circuit detecting circuit 2 compares the both-terminal voltage of the resistance Rs with the reference voltage produced by a Zener diode ZD and resistances R5 and R6 through a comparator CP. Thus the circuit 2 detects a short circuit between both lines L1 and L2. A feedback circuit 3 receives the output of the circuit 2 and changes the input terminal voltage levels of both amplifiers OPa and OPb to low levels to keep the outputs of both amplifiers at the same level.

IPC: G01F1/74
Filed: 1989-10-24
Abstract: PURPOSE:To exactly measure the flow rate of pulverized coal by adding a measurement reaction accelerator which is made higher in specific dielectric constant than the pulverized coal into the two-phase fluid in the flow passage on the upstream side of a correlation speedometer. CONSTITUTION:A control valve 23 is temporarily opened by a specified amt. to supply the measurement reaction accelerator 18 in a storage body 22 by as much as needed into a flow passage at every measurement of the flow rate of the pulverized coal 12 at the time of measuring the flow rate thereof. The accelerator 18 is then mixed with the two-phase fluid 14 run and fed in the flow passage 15 and is sent at the same speed as the speed of the pulverized coal 12 in a transporting direction F so as to pass the correlation speedometer 17. Since the accelerator 18 has the specific dielectric constant larger than the specific dielectric constant of the pulverized coal 12 at this time, the accelerator 18 is detected as a large change component in electrostatic capacity by electrodes 20a, 20b and 21a, 21b for flow velocity detection of upstream and downstream detectors 20, 21 and the waveforms of the upstream and downstream side electric signals are largely developed. The delay time as the fluctuation signals of these signals is thus easily determined. The flow velocity and concn. of the pulverized coal 12 are, thereupon determined and the flow rate within the sectional area of a piping 11 is determined.

Title: Piston of internal combustion engine
Inventor: NISHIURA KOICHI
IPC: F16J1/16
Filed: 1990-10-16
Abstract: PURPOSE:To reduce respective well-balanced stress of surface pressure, tension and compression acting on a pin boss and prevent the pin boss from damages by making the lateral width of a recess smaller than that of an inner wall surface while forming the recesses in the inner wall surfaces of left and right pin bosses. CONSTITUTION:Left and right pin bosses 1 are formed in the inner wall surfaces 1a with recesses (slits) 3 near piston mounting holes 2 respectively. The lateral width (a) of the slit 3 is made smaller than that (b) of the inner wall surface 1a of the pin boss 1. When gas pressure P acts on a piston head 5a and a load F acts on a piston 4, the pin boss 1 is elastically inside deformed so that contact areas of the upper surface 4a of the piston 4 and the upper surface 2a of the piston mounting hole 2 are increased to disperse the surface pressure. Since the pin boss 1 is elastically deformed on the tip part, a compression force of the pin boss 1 acting on the boundary part 6 to the top 5a of the piston on both sides of the slit 3 is dispersed. Tensile stress acting on the proximity 2b of the upper surface of the piston pin mounting hole 2 can be reduced by the elastic deformation of the pin boss 1.
