Title: Sheet-brush material and brush structure
Inventor: NOROTA SUSUMU
IPC: B21B45/02
Filed: 1989-09-28
Abstract: PURPOSE:To obtain a brush which has washing ability, wear-resistance and blinding resistance by providing plural grooves parallel to each other on the surface of a synthetic resin sheet piece in which abrasive particles are mixed, and arranging and stacking the sheets in such a manner that the directions of the grooves are aligned. CONSTITUTION:Plural grooves parallel to each other are provided on the surface of a synthetic resin sheet piece, which is mainly composed of meta-group aromatic polyamide and has abrasive particles mixed in the interior thereof. Plural sheets of the above sheet-brush material are arranged and stacked in such a manner that the directions of the grooves provided on the surface of the brush material are aligned to form a structure. A part of the stracture is fixed by adhesive resin to obtain a brush structure. In the case of making a rotary roll brush using the above brush structure, adhesive resin is applied to the inner walls of the grooves of a grooved roll, and the brush structure is planted by sequentially making the brush structure closely adhere to the grooves to fill up the grooves. If the rotary brush roll is used for washing the surface of a grooved steel plate (for removing foreign matter such as iron powder, oil or the like), the surface washing effect can be improved and the cycle of changing washing liquid can be reduced.

Inventor: FUJIWARA GORO
IPC: B41J15/16
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent sagging from occurring in a roll sheet wound in a roll. SOLUTION: A roll sheet S is mounted on delivery rollers 108 and 109 arranged with a predetermined distance in between. When the delivery rollers 108 and 109 drive in the clockwise direction, the roll sheet S rotates in the counterlockwise direction and a sheet S1 is sent out. In such a case, a frictional force between the delivery rollers 108 and 109 and sheets is set smaller than a frictional force between the sheets for preventing occurrence of slipping of the sheets of the roll sheet S after two rotations which tries to keep on rotating due to inertial force when a delivery rotation is stopped.

Title: Automatic document feeding system copying machine
Inventor: MAEHARA SHIGEJI
IPC: G03G21/14
Filed: 1988-10-04
Abstract: PURPOSE:To improve a performance by detecting the edge of the downstream of a document in the vicinity of an exposing region and making it a start signal which counts a prescribed set time. CONSTITUTION:The outer peripheral surface of a first rotating supporting drum 47 is irradiated with the light of the element 52. Since the peripheral surface is low in reflectance and hardly reflects light, the light of the element 52 does not reach the element 53 and the element 1 becomes 'off' condition. When the document D is fed to the supporting drum 47 and passes through a switching region 54, the element becomes 'on' from 'off' since the document D is high in reflectance. After that, when the edge of upstream Dr passes through the region 54, it becomes 'off' from 'on'. Corresponding to these 'onb and 'off', a signal required at the start and end of scanning is outputted.

Title: Medical laser device
Inventor: YANO NOBUYUKI
IPC: A61F9/008
Filed: 1988-10-05
Abstract: PURPOSE:To make it possible to efficiently form a lase beam from a semiconductor laser source into a small circular uniform spot by attaching a tapered fiber member to the light emitting surface of the semiconductor laser source. CONSTITUTION:A tapered fiber member 16 is attached to the light emitting surface of a semiconductor laser source 15. The tapered fiber member 16 is thin at its light incident side and is gradually fattened toward the emitting side. A light ray incident upon the incident side of such a fiber member 16 at a large angle, becomes more and more parallel with the optical axis of the fiber member 16 due to multiple reflection within the fiber. Thereby it is possible to restrain the divergence of the light beam at the emitting side of the fiber member so as to be smaller than that obtained be conventional fiber members.

Abstract: PURPOSE: To measure the rotational deviation of an object in high accuracy by directing a laser light onto a cyclic pattern prepared on the object. CONSTITUTION: An object 1 to be tested is placed on a sample table 10 and the pitch direction of diffraction grid 2 prepared on the object 1 is aligned with a reference direction x, then the table 10 is shifted by using x and y stages 14 and 12 so that a light beam 3 may be directed to a grid 2. ±n-th diffracted lights 5 and 6 of the grid 2 irradiated by the beam 3 are made incident into the point symmetry points 8 and 9 on the surface that is vertical against a 0-th diffracted light 4 of light detecting means 17 and 18.

Abstract: PURPOSE:To display the arrival direction and elevation of a radio wave and the distance to a radio wave emitting point, by measuring the arrival direction and amplitude value of the phase change component of a receiving signal obtained by arranging a non-directional antenna and comparing both of them with reference values. CONSTITUTION:A frequency correction circuit 6 converts an azimuth signal, of which the amlitude changes in proportion to frequency, to an azimuth signal with constant amplitude regardless of frequency and an internal signal circuit 8 generates a rectangular wave group comprising the relation of frequency same to and integer times to that of the azimuth signal. A reference signal generation circuit 2 generates a SIN wave synchronous to the internal output signal and multiplies the same by both rectified waves of the azimuth signal to integrte the area of the product output signal thereof on the basis of a polarity signal. The phase of the internal output signal is controlled by this integrated result and follows that of the azimuth signal while the sum total of preset values F4 come to a radio wave arrival direction. When the azimuth of a radio wave is determined, the amplitude of an azimuth is calculated and compared with the content 11 of memory 10 while an azimuth, elevation and a distance of values coincided with or nearest to said amplitude value are displayed by an azimuth display device 12.
