Title: Automatic mechanism for turning over page
Inventor: AOKI MASATO
IPC: G06F19/00
Filed: 1994-07-04
Abstract: PURPOSE:To shorten a time required for turning over a page by a method wherein a part of a roller for pressing a surface of a page to be turned over is made of a frictional member, and a hooking part for curving the page by hooking the top of the page warped by the roller is provided on an arm. CONSTITUTION:A turn-over roller 10 is made of a smooth material, such as a resin. Only a part of the periphery of the turn-over roller 10 is made of a frictional member 28. When the frictional member 28 comes into contact with a page, the first page is warped upward with the rotation of the turn-over roller 10. With the further rotation of the turn-over roller 10, the top of the page is released from the frictional force of the turn-over roller 10 by the restoring force of the paper, and the page in the warped state is hooked by a hooking part 27. In another rotation of the turn-over roller 10, when the frictional member 28 comes into contact with a page, the second page is warped upward with the rotation of the turn-over roller 10. With the further rotation of the turn-over roller 10, the second page is lapped with the first page, and the top of the page is hooked by the hooking part 27. In this manner, a time required for turning over a page can be reduced.

Generally, the clearance between the shaft 4 and the inside diameter of the sleeve part 5 is commonly several mum to tenodd mum, and this value differs according to the specifications of the bearing 1, and determines the performance of the bearing 1. By applying the copper alloy plating (a) on the inner surface of the sleeve part 5, the inside diameter is worked larger by the portion of the thickness of the plated layer, and the prescribed inside diameter is obtained by adjusting the plated layer (a). In this case, the plated leyer (a) is formed so as to fill the unevenness of the inner surface in the foreworking.

Title: Photoirradiation method
Inventor: HOSHINO HIROSHI
IPC: G02F1/1333
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To rapidly execute a photochemical action, to make a contribution to energy conservation and to improve productivity by making the light from a light source incident at a specific incident angle on the end face of a transparent substrate and irradiating a body with the light from the inner side of the substrate. SOLUTION: The light from the light source is made incident at the incident angle of <=50 deg. on the end face of the transparent substrate 1 and the object to be irradiated on the transparent substrate 1 is irradiated with this light from the inside surface side of the substrate. Optical fibers 6 make the light from a lamp 3 on the end face 1A at the incident angle of 0 deg. and if the light is made incident at the incident angle of <=50 deg. in order to smooth total reflection and to lessen the loss, the light is well introduced into the transparent substrate 1. The incident light advances while making total reflection. The light is not totally reflected and absorbed in the portion adhered with a thin-film material 2 having a refractive index greater than the refractive index of the air.  The light energy is used for the photoreaction of the thin-film material 2 with high efficiency. The light repeats the total reflection within the transparent substrate 1 until the light attenuates. This light energy is effectively used and the photoreaction with the thin-film material 2 is carried out efficiently. The improvement in the productivity of the liquid crystal display element is thus made possible.

Title: Control method for robot cooperatively transportating object, and device therefor
Inventor: ARAI HIROHIKO
IPC: G05B19/18
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To intuitively grasp behavior of an object by a person at the time of controlling a robot cooperatively transportating the object for transporting it in cooperation with the person by limiting directions in which it can move. SOLUTION: When controlling a robot cooperatively transporting an object, force exerted from an object 4 is detected by an inner force sense sensor 5, and based on a rotary force component τ around a vertical axis and a translation force component Fx in a long axis direction of the object 4 separated from a signal detected by the inner force sense sensor 5, a rotary motion component around the vertical axis and a translation motion component in the long axis direction of the object 4 are outputted with setting a gain such that resistance of the robot becomes small. On the other hand, a translation motion component Fy in a short axis direction of the object 4 is restricted so as not to generate translation motion in the short axis direction of the object 4.  A robot arm is thereby driven with limiting movement to the object 4 so as to be equivalent to a limitation when the object 4 is supported by an imaginary wheel turning to the long axis direction of the object 4 at a point on the robot side.

IPC: G01R31/00
Filed: 1991-06-25
Abstract: PURPOSE:To enable an IC which is sucked in vacuum to be released in a tool for inspecting a high-power TAB-type IC while cooling it.

Title: Heating device and image forming device
Inventor: MIYAGAWA HIDEAKI
IPC: H05B6/14
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To control the temperature at a fixed temperature without using a complicated control circuit, by making up a part of a magnetic core corresponding to an induction heating member out of a magnetic shunt alloy with a saturation magnetic flux density to be reduced at a desired controlled temperature or higher. SOLUTION: When a high-frequency current is passed through a primary coil 3, a high-frequency magnetic flux flows through a magnetic core 1 including a magnetic shunt alloy part 2, an induction current flows through a fixing roller 4 or a secondary coil, which is heated by Joule heat generated by the induction current. When the current continues to be passed through the primary coil 3, the temperature of the fixing roller 4 rises, and when it exceeds a fixed temperature, the temperature of the magnetic shunt alloy part 2 also rises until it exceeds a fixed temperature, and the saturation density of magnetic flux capable of passing through the magnetic shunt alloy part 2 is decreased.  Accordingly, the saturation density of magnetic flux passing through the magnetic core 1 is also decreased, therefore the induction current produced in the fixing roller 4 is also lowered to lower its temperature. In contrast with this, when the temperature of the fixing roller 4 falls below the fixed temperature, the temperature of the fixing roller 4 is raised by means of the magnetic shunt alloy part 2 and kept at the fixed temperature.

Title: Protective unit for thyristor circuit
Inventor: KANAI TAKEO
IPC: G05F1/10
Filed: 1991-06-26
Abstract: PURPOSE:To prevent concentration of current to one circuit of thyristor by providing means for detecting self-firing of one or a plurality of thyristors in parallel circuits, and means for delivering firing pulses to all thyristors in response to the detecting means. CONSTITUTION:When a VBO free thyristor 11 is fired with an overvoltage, voltage to be born by a VBO free thyristor 12 increases and thereby the VBO free thyristor 12 is fired substantially simultaneously. Consequently, one of three parallel circuits, including the VBO free thyristors 11, 12, is fired and a current flows through the VBO free thyristors 11, 12. The current is detected through a current detector 50. When the current exceeds a preset level, a level detector produces an output. An AND circuit 53 then produces a logical product of the firing signal due to overvoltage and the inverted signal of an ON command. Consequently, the VBO free thyristor is fired even if an OFF signal is not provided and a current flows the VBO free thyristor.
