Title: Ink injection angle adjusting device in ink jet printing apparatus
Inventor: FURUKAWA ISOKAZU
IPC: B41J2/12
Filed: 1979-09-29
Abstract: PURPOSE:To adjust an irregularity of ink injecting directions by a method wherein the charging electrodes the charging loads thereof would be varied in response to the locus of the ink injection are arranged under a special construction, while, a variation of the charging load is detected by sensing electrodes and compared with a reference voltage. CONSTITUTION:The ink drips from the ink injection head 1 are charged with the charging electrodes 5a, 5b, being deflected by deflection electrodes 7a, 7b and printed on a printing paper 9. Ink drips not required are recovered by a gutter 8, and applied to their reuse. Electrodes 5a, 5b are arranged in a direction perpendicular to the deflection electrodes 7a, 7b as well as under a shape, for example, a triangular shape having a variable electrode area in a direction in which the ink drips are deflected. A variation of charging load to be caused by an irregularity in ink inject- ing direction from the head 1 is sensed by a sensing electrode 6. The variation is detected as a voltage, compared with a regular voltage in a comparator 15 to operate the ink injection adjustor 16 and to print the ink drips at their normal positions.

Abstract: PROBLEM TO BE SOLVED: To supply light for sufficient quantity even in the case of use for an endoscope provided with a thin light guide by providing a light quantity cut mask for limiting the quantity of incident light near the incidence plane of the light guide. SOLUTION: Near the incidence end of a light guide 1, a light quantity cut mask 2 for limiting the quantity of light made incident to the light guide 1 is provided just before the incidence end of the light guide 1.

Since the light quantity cut mask 2 is provided so that the light made incident through the opening 3 to the light guide 1 does not exceed quantity more than a fixed level because of the light quantity cut mask 2 even in the case of use for the endoscope of a thick light guide 1, however, any problem such as heating at the top end of the endoscope does not occur.

Title: Vacuum cleaner suction tool and vacuum cleaner
Inventor: FUJITA KOICHI
IPC: A47L9/00
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To make a vacuum cleaner more silent by eliminating projections between a suction chamber and a suction passage, thus decreasing the resistance to passage of air, and preventing turbulent flow. SOLUTION: A lead wire C67 is drawn in from one side of a connecting pipe 22 and is drawn out again from the other side of the connecting pipe 22. When electronic parts such as connectors, switches and electric motors need to be electrically connected to both sides of the connecting pipe 22 by means of lead wires, the necessity of providing bridging parts or the like outside the connecting pipe 22 is eliminated, thus eliminating obstacles on a suction passage, and securing a smooth suction passage, with the result that noises caused by turbulent flow and wind noises are reduced to make a vacuum cleaner more silent.

The non-permeated liquid is discharged through an outlet 8. The above- mentioned pipe 11 is made longer by >=30% of the length of the hollow yarn membranes; therefore, the flushing liquid of a high velocity from the pipe 11 intrudes into the dead spaced places where the contamination of the membranes progresses and removes effectively the contaminants of the membranes in the stage of washing the membranes.
