Title: Center with claw
Inventor: WASHIZU RIYOUZOU
IPC: B23B23/00
Filed: 1980-11-07
Abstract: PURPOSE: To make the contact surfaces of a center with a claw more difficult to be damaged than those of conventional ones, by causing line contact between the rear conical surface of the pressure contact claw for a lathe or the like and the oblique surface of a moving member.  
     CONSTITUTION: A center fith a with a claw 25, which is fitted in the spindle of a machine tool such as a lathe and a cylindrical grinder to support a work- piece, has a step 11 at the front end of a sliding fit hole 4. A moving member support plate 12 is put in pressure contact with the step 11. Positioning pins 31 are placed in contact with the front surfaces of slender holes 30 in the head of the center and with the rear surfaces of slender holes 30 of the shaft 21 of the center. When a moving member 19 is caused to move in the radial direction of the body of the center, moment which would rotate the claw 25 around its axis is not caused because the force acting from the oblique surface 20 of the moving member 19 to the rear conical surface 27 of the claw is oriented toward the axis of the center. For that reason, the tip of the claw 25 cannot be damaged. Since the rear conical surface 27 of the claw 25 and the oblique surface 20 of the moving member 19 are put in line contact with each other, the contact surfaces are more difficult to be damaged than those of conventional centers with claws.

Title: Exhaust turbo supercharger for internal combustion engine
Inventor: HOSHINO HARUHIKO
IPC: F02B37/00
Filed: 1986-07-07
Abstract: PURPOSE:To accelerate the increase of the supercharge pressure by controlling a waste gate valve so as to be opened when an exhaust selecting valve is closed over a prescribed opening degree, thus reducing the turbine outlet pressure of an exhaust turbo supercharger having a small capacity.

Title: Vortex flowmeter
Inventor: TAMURA HISASHI
IPC: G01F1/32
Filed: 1981-10-06
Abstract: PURPOSE:To obtain the device having an excellent S/N ratio and vibration resisting property, with regard to the measurement of the flow speed and the flow rate of fluid by utilizing K arm an vortex, by arranging two piezoelectric sensors in a concave part with a specified interval being provided, converting each sensor output and then performing computation, thereby effectively removing the effect of the noise due to the disturbing vibration. CONSTITUTION:When the fluid to be measured flows in a pipe, a vortex generating body 13 generates the K arm an vortex and receives a lift change. Bending moment MV is acted on a sensor part 14, and approximately linear stress distribution is generated. The vortex generating body 13 receives the force whose direction is the same as the lift of the vortex by the disturbing vibration excited by a pump and the like. The bending moment is acted on the sensor 14 in respective modes. As a result, in the charges q1 and q2 detected by the piezoelectric sensors 14a and 14b, the noise charge due to the vibration and the strain in the pipe is superimposed on the signal charge caused by the life of the vortex. When the piezoelectric sensors 14a and 14b of the sensor part 14 are arranged at two points (P and Q) where the noise charge due to the vibration of the vortex generating body 13 becomes zero, the effect of the noise due to the disturbing vibration can be effectively removed.
