Title: Device for wiping waterdrops off side mirror of automobile
Inventor: SANUKI TOMOAKI
IPC: B60S1/60
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To enable easy mounting at low cost and to wipe waterdrops off a side mirror surface by a method wherein a pipe to introduce air to an air exhaust port is arranged in an air intake port formed in a position wherein a flow of air generated when an automobile runs is easily inputted and the mirror surface is placed in the air exhaust port.

SOLUTION: When an oil component contained in a waste liquor is separated, the liquid pressure of a liquid storage tank is adjusted by adjusting the quantity of the waste liquor to be injected into a waste liquor injection cylinder by a waste liquor injection quantity adjustment valve. Next the waste liquor injected into the waste liquor injection cylinder is guided into the liquid storage tank through a waste liquor guide cylinder, the oil component with a low specific gravity being collected at the upper part of the liquid storage tank and water and a water-soluble component with a high specific gravity being collected at the lower part of the liquid storage tank. Consequently, the two separate upper and lower layers, each for the separated oil and the separated water are present.  In this case, a separated guide cylinder 32 for guiding the oil of the separated oil layer is provided in such a fashion that the elevation of the outlet of the cylinder 32 is variable. Thus, it is possible to adjust the pressure at the outlet part of the separated oil guide cylinder 32 and maintain the outflow velocity of the separated oil overflowing from the outlet of the separated oil guide cylinder 32 at a correct value.

Title: Color-selecting apparatus
Inventor: ISOTANI KEIICHI
IPC: B07C5/342
Filed: 1996-12-22
Abstract: PROBLEM TO BE SOLVED: To enable even an object to be detected, which is unstable in shape or size to be color-selected by having a color-detecting unit below an extended line of a guide face of an edge of feeding means, and detecting color or a tone of a lower surface of the object to be detected dropping through the edge of the feeding means. SOLUTION: A color-detecting unit 21 is provided at a position of several to tens of millimeters apart from an edge of a feeding conveyer 1 and below a dropping trajectory R of an object to be detected W. When the object to be detected W sliding down on the feeding conveyer 1 passes over the edge of the feeding conveyer 1, regardless of the shape or the magnitude of the object to be detected W, the lower surface of the object to be detected W rushes toward a direction (r) of an extended line of the conveyer surface of the edge portion of the feeding conveyer 1 and drops along the dropping trajectory R. Consequently, when the object to be detected W, successively fed by the feeding conveyer 1, is rushing out from the edge of the feeding conveyer 1, the color of the lower surface is detected by the color-detecting unit 21.
