Title: Roll paper feeding device
Inventor: ABE TAKASHI
IPC: B65H19/10
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent the jam to be generated caused by the slack of a roll paper and damage of the roll paper when the roll paper is automatically drawn out and nipped by conveying rollers. SOLUTION: Many guide rolls 26a are provided on a guide sheet 26 for partially covering a roll paper 100. A shaft 27b fixed on one end of the guide sheet 26 can be moved in a guide groove 30 provided on the side surface of a frame body 24. The other end 27a of the guide sheet 26 is fixed to the frame body 24 through a tension spring 28a. When a paper feeding cassette 21 is mounted on a main body frame, a locking plate on the main body frame side moves the shaft 27b to one end of the guide groove 30. As a result, the guide sheet 26 is wound on the roll paper 100 and pressed the front surface of the roll paper 100, and therefore, the slack of the roll paper 100 is prevented. The tip of the roll paper 100 is caught by a peeling pawl 32 and separated from the lower layer.

Title: Ignition timing control device
Inventor: HARASHIMA SHIGEKI
IPC: F02P3/045
Filed: 1992-12-28
Abstract: PURPOSE:To provide an ignition timing control device which can surely prevent ignition drop-out even if engine revolutions are abruptly changed. CONSTITUTION:Revolution reference pulses every one revolution and revolution pulses every one specified rotation angle, that is, 30 deg. in this case, are outputted from the distributor 17 of an internal combustion engine. These pulses are read in a control section 18 so as to be processed by the control section 18, so that an ignition signal is thereby outputted. When revolutions are fluctuated in a small range, ignition is controlled by an estimated ignition time estimated based on the read-in time for the revolution pulse. When revolutions are abruptly increased, since there is possibility that accuracy of the estimated ignition time can not be kept as usual while being accompanied by ignition drop-out, the estimated ignition time is corrected based on time required for reading the specified number of revolution pulses, so that ignition drop-out is surely prevented.

Title: Method for preventing loosening of wire reeled for binding reinforcement
Inventor: HAYASHI SUSUMU
IPC: B65H65/00
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To prevent the loosening of a wire reeled for binding reinforcement. SOLUTION: A reel is mounted in a wire winder, and the wire is taken up at a specified take-up torque, and pressure is applied to the outer periphery of the wire W in the direction to the radial center of the reel by the chuck 4 of a chuck type pressing machine.

Title: Method for overlapping semiconductor wafer
Inventor: HASHIMOTO MAKOTO
IPC: H01L21/26
Filed: 1991-12-11
Abstract: PURPOSE:To lower an overlapping temperature while defoaming by irradiating a laminated semiconductor wafer with an electromagnetic wave of a wavelength range to be absorbed by water molecules at the time of annealing. CONSTITUTION:Two semiconductor wafers 1a, 1b are first overlapped at the ambient temperature. Then, it is irradiated with an electromagnetic wave of a wavelength range to be absorbed by water molecules at the time of annealing. When only water molecules generated by dehydrating and condensing the wafers 1a, 1b are selectively heated, a diffusion coefficient of the molecules is raised, and the diffusion of the molecules is advanced. Thus, only the molecules can be heated by the irradiating wave without heating the wafer to a high temperature, the diffusion constant of the molecules is increased thereby to effectively diffuse the molecules. Accordingly generation of foams due to water on the overlap surfaces can be prevented.

Title: Indicated position detection device for display device
Inventor: KONNO RYOICHI
IPC: G06F3/0346
Filed: 1993-12-29
Abstract: PURPOSE:To easily indicate a position on a large screen by irradiating the screen with visible light, photodetecting light transmitted through the screen and a position information layer by a photodetecting means, and discriminating the position on the screen by a discriminating means. CONSTITUTION:The position information layer 21 is formed by printing a bar code which has universal directivity on the back surface of, for example, the screen 13 by using light-shielding ink. An image is projected by a projector 12 on the screen 13 and an operator points an optional position on the screen by using an indication device 14. The majority of the light from the projector 12 is cut off by the screen 13 and laser light is transmitted through the screen 13 to reach a photodetecting element 23. The light is converted by the photodetecting element 23 into an electric signal, which is converted by an A/D converter into a digital signal to generate positional information that the bar code has, and, the positional information is converted into logical data corresponding to X-Y coordinates on the display surface by a decoder. A host computer 11 compares the data with positional information previously sent out to the projector 12 to know the current indicated position.

Title: Method and device for transfer-molding resin
Inventor: PIITAA BANKUROFUTO REONI
IPC: B29C43/12
Filed: 1991-12-13
Abstract: PURPOSE: To achieve good yields, totally uniform saturation of preforms, and high fiber-to-resin ratios by utilizing staged pressurization to a rigid mold and a deformable mold and by removing excess resin. CONSTITUTION: The pressure differential between a first pressure P1 in a pressure chamber 38 exerted through a bladder/liner 36 and the pressure in the space 52 exerted by the injection resin is of magnitude to bias conformable cauls 32 away from corresponding surface 16 of the rigid female mold 14, thereby causing the space 52 to expand beyond its net dimensions, facilitating resin flow throughout the fiber reinforcement layer, which ensures complete saturation of the fiber reinforcement layer. The pressure is raised to a second predetermined pressure P2 , the pressure transferred through the bladder/liner 36 uniformly biases the conformable cauls 32 and restores it to the net dimensions of the composite product, and expels excess resin through a vent path 28 with the uniform biasing action exerted by the conformable cauls 32.  This provides complete swoller fiber and increase the fiber-to-resin ratio of the resin- impregnated fiber reinforcement layer.
