Title: Recorder
Inventor: TSUKADA ISAO
IPC: B41J19/00
Filed: 1989-02-14
Abstract: PURPOSE:To realize accurate and stable carriage feeding and to obtain a printing quality by composing not to transmit power when a gear lack part of a timing belt is disposed at a position of a belt driving pulley, and repeating an operation of rotating at a predetermined distance after a drive source is reversely rotated at a predetermined distance. CONSTITUTION:When a belt driving pulley 125 starts rotating in a direction A, a belt 106 is moved in the direction A by the mutual frictional force between the gear lack part of a belt and the pulley 125. In this case, since the teeth of the pulley 125 are not synchronized with the toothed part 106C of the belt 16, the crests of the gears are ridden over the other. A stepping motor 107 is reversely rotated at this position from the direction A to a direction B. Since an inertial load due to the mass of a carriage 105 is generated at the time of reverse rotation of the pulley 125, a force resisting against the reverse rotation is generated at the belt 106, and the pulley 125 follows to the direction B at a high speed. Thus, the riding contact of the crests of both the gears is deviated, and both are returned to a normally engaging state.

Title: High frequency heating apparatus
Inventor: IWABUCHI YASUSHI
IPC: H05B6/78
Filed: 1990-02-15
Abstract: PURPOSE:To exhibit an attenuating effect over a wide frequency band by arranging a plurality of U-shape metallic bodies having the same size which have been formed by means of bending a metal plate in a U-shape in a moving direction of a belt and then by providing electric wave attenuating grooves alternately having difference in depth by thickness of the metal plate. CONSTITUTION:By bending both sides of a first face 7a joined to a wall of a passage 6 in an approximately right angle, a second face 7b and a third face 7c which are facing each other inside the passage 6 are formed. As a plurality of U-shaped metallic bodies 7 are arranged along a moving direction of a belt 2, the U-shaped metallic body 7 itself is an electric wave attenuating groove A10 with a depth of a distance D1 from the first face 7a to the second face 7b or to the tip of the third face 7c, while an interval between the adjacent U-shaped metallic bodies 7, 7 is an electric wave attenuating groove B11 having a depth of a distance D2 from a peripheral wall inner face to the second face 7b or the third face 7c which are facing each other. Thus by appropriately selecting the depths D1, D2, an electric wave sealing structure having a sufficient attenuating effect over a wide frequency band can be obtained.

IPC: H04N19/51
Filed: 1992-02-21
Abstract: PURPOSE:To detect a local motion vector in a short time. CONSTITUTION:A two-dimensional BPF 12 extracts a prescribed space frequency component out of an input image, and a zero-cross detecting circuit 14 binarizes the extracted frequency component. Then, a memory 18 delays the output of the circuit 14 by an extent equal to a single field period, and a shift register 16 shifts vertically and laterally the images of a present field within a screen. An exclusive OR circuit 20 calculates the difference between the binary images of different times and integrates this difference in a prescribed block. A least value detecting circuit 22 outputs the shift value with which the output of the circuit 20 is minimized as a motion vector. The center passing space wavelength lambdap of the BPF 12 is set larger than a shift range Rp of the register 16.

IPC: H01H33/88
Filed: 1988-02-19
Abstract: PURPOSE:To prevent strength of a needle from being reduced and make it be compact by composing exhaust outlets formed in radial direction of the needle into slots formed such that its length in axis direction of the needle is longer than its width in circumferential direction of the needle or a plurality of apertures dispersed in the axis direction. CONSTITUTION:A sucking buffer type switching apparatus consists of a hollow portion comprising a hollow moving piece 8, a gas passage hole 9 and an exhaust outlet 21 and a suction chamber 10 comprising a piston 11 and a cylinder 12. The exhaust outlet 12 interfacing the gas passage hole 9 and the suction chamber 10 is composed into a slot which is formed such that its length in axis direction of the moving piece 8 is longer than its width in circumferential direction of the needle 8. Gas stream is prevented from being remained by defining an area of the exhaust outlet 21 into being larger than that of the gas passage hole 9. When the needle 9 is moved to right, arc is generated since a stator 7 and the moving piece 8 are separated each other, however, negative pressure is generated at the same time due to increase of the capacity of the suction chamber 10 so as to extinguish the arc. By arranging the configuration of the exhaust outlet 21 as mentioned above, the needle 8 and the whole of the apparatus can be made compact.

Title: Rotary polyhedral mirror
Inventor: KAMEYAMA TOORU
IPC: G02B26/12
Filed: 1983-03-04
Abstract: PURPOSE:To relieve considerably the permissible value for the flatness of specular surfaces and to work easily a rotary polyhedral mirror by making the cut shape of each plane mirror uniform in roughly the same distortion shape when the rotary polyhedral mirror is cut at the plane intersecting orthogonally with a revolving shaft. CONSTITUTION:All the curving shapes of the respective specular surfaces of a rotary polyhedral mirror 1' are made uniform in the same shape and the rates of curving are also made roughly uniform. The shape of a broken line indicates the case of a projecting shape and an alternate long and short dash line indicates the case of a recessed shape. The shapes are made roughly the same arc and the rate delta of curving is made roughly the same as well, in either case. If the curving shapes of the respective specular surfaces are made uniform in the same shape in the above-mentioned way, all the scanning end points of the specular surfaces gather near B' and B'' point without varying. It is easier to curve the specular surface than to obtain flatness and if the shapes of the specular surfaces are deliberately curved to the uniform shape in the above-mentioned way, the flatness of the specular surfaces can be fairly relieved and the working of the specular surfaces is considerably easy.
