Title: Pneumatic box
Inventor: SHINKAI KUNIO
IPC: D01H11/00
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic box capable of narrowing the width and readily utilizing recovered cotton wastes. SOLUTION: This pneumatic box is obtained by dividing a pneumatic box body 11 into a cotton collection chamber 15 and a suction chamber 16 with a filter net 14 crossing the longitudinal direction of the frame at right angles, arranging both the chambers 15 and 16 side by side in the longitudinal direction of the frame and arranging a suction unit 22 prepared by connecting an impeller 21 to a motor 20 in the suction chamber 16 so as to keep the rotation axial line of the impeller 21 parallel to the filter net 14. The total length of the suction unit 22 is smaller than the outside diameter of the impeller 21. Since the cotton collection chamber 15 hardly has a change in the flow direction of a suction air stream, fibers in cotton wastes B sucked on the filter net 14 can be prevented from mutually twisting and entwining without moving the cotton wastes B along the filter bet 14.

Abstract: PROBLEM TO BE SOLVED: To store an open case while being extended when not being used by keeping a box body shape by combining one blank and the side surface sections of the other blank at four corner sections of an open surface of a box body, in an open case wherein two sheets of the rectangular blank are superposed into a cross-shape, and the box body shape is formed by bending the height dimension portion of both end sections. SOLUTION: A hollow synthetic resin sheet 11 is manufactured as a long-sized article having the longer edge dimension width of a box body. Then, the long-sized article is formed into a sheet-form body having a length for which the double box height dimension is added to the shorter edge dimension. Then, folding sections are formed on the sheet material. In this case, one folding section is formed at a boundary line section between the bottom surface section and the side wall section. The other folding section is formed at a folding-back section of the side wall section. The former is bent by 90 deg., and the latter is bent by 180 deg.. At the time of a building-up of the box body, two sheets of the hollow synthetic resin sheets 11 and 12 are superposed into a cross-shape.  Then, the superposed section is made the bottom surface, and the height dimension portion of both end sections is bent to form the side wall section. In this case, adjacent side surface sections are brought into contact with each other, and the box body shape is kept using an L-shaped corner member 6.

Title: Lighting device for on-vehicle discharge lamp
Inventor: KAWABATA MUNEHIRO
IPC: B60Q1/04
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To miniaturize a lighting device, reduce cost, and prevent any traffic accident even when right and left discharge lamps simultaneously turn off by detecting lighting-out of the discharge lamp with a pair of lighting-out detecting circuits connected between the discharge lamp and a lighting driving portion and by lighting an emergency light parallel with the discharge lamp based on the detection result output. SOLUTION: Voltage from a direct current power supply 1 is supplied to a DC/DC converter 2 to rise power supply's voltage, and the high voltage is outputted from an H-bridge 3. An igniter circuit 5 furthermore rises the received high voltage to impress it to a discharge lamp 4, outputs light generated by arc discharge, and continues this state. When a failure occurs in a control circuit 15 to light out right and left discharge lamps 4 simultaneously, lighting- out detecting circuits 12 output lighting-out detection signals. An emergency light lighting circuit 13, when receives signals from the respective lighting-out detecting circuits 12, lights a high beam lamp 14 parallel with the discharge lamps 4. Thus, low cost can be realized in a small device, and any traffic accident can be prevented even when right and left discharge lamps 4 simultaneously turn off.
