Filed: 1978-07-27
Abstract: PURPOSE: To raise the efficiency of dust collection by designating specifically the structure and arrangement of dust collecting pole and discharge pole.  
     CONSTITUTION: The dust collecting pole 1 consisting of corrugated type or continuous groove type of flat plates and the discharge pole 2 consisting of bars having the needle-like projections 3 in parallel with the direction of flow of gas and the needle- like projections 4 right-angled to the direction of flow of gas are arranged and the discharge pole 2 is put at the center between the lead-in portions of the dust collecting pole 1. Thus, the distance between the needle tip of the needle-like projection 4 right-angled to gas flow direction becomes wider, whereby spark is prevented and the application of higher voltage is made possible and also the thermal expansion of the dust collecting pole 1 is prevented and the functions of the dust collecting pole 1 and the discharge pole 2 are made higher. Thus, target can be attained.

Abstract: PURPOSE:To improve the operability of a mouse, by using one of push button switches on the mouse as a temporary signal switching means, and exchanging the displacement quantities in the longitudinal and the lateral directions of the mouse while the said push button is depressed. CONSTITUTION:When one output signal S1 of the push button switches on a mouse 1 is at '1', AND gates 5a, 5b, 7a, and 7b are opened, and AND gates 6a and 6b are closed. As a result, the outputs YA, and YB of the mouse 1 are outputted to a counter part 2, and the outputs XA, and XB of the mouse, to a counter part 3, and they are outputted from the counter parts 2 and 3 as the displacement quantities DELTAY, and DELTAX of the X and Y respectively. By depressing the push button switch on the mouse, and setting the output signal S1 at '0', the AND gates 5a, 5b, 7a, and 7b are closed, and the AND gates 6a and 6b are opened, therefore, displacing output signals XA and XB in the X direction of the mouse are inputted to the counter part 2 which outputs the displacement quantity DELTAY of the Y. At such a time, nothing is inputted to the counter part 3, and the displacing output signals YA and YB in the Y direction of the mouse can be inputted to the counter part 3.

Title: Image sensor and information processor using these
Inventor: OGURA MAKOTO
IPC: H04N1/028
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and weight by substantially integrating a rod lens array image-forming light from an original at a sensor chip with a light receiving pixel and an illuminating means illuminating the original to make combined structure so as to arrange precisely. SOLUTION: The rod lens array 3 is included in a recessed part 4 formed on a light transmission body 4 to be positioned. As the pawl part 4b of the body 4 is fixed by biting, both parts are substantially integrated. As deformation such as wrap at the time of molding both parts is more reinforced and interpolated than the case of being used by a single body by integrating. The directions of deformation in an integrated state are matched to make a structure which is difficult to receive its influence. Since the array 3 is precisely arranged to the body 4, condensing width of illumination is narrowed to reduce power consumption and the common length (Tc) of the array 3 is shortened to attain miniaturization and lightening in weight.

Abstract: PROBLEM TO BE SOLVED: To eliminate generation of slip, and to remove water even at a high- speed conveyance by driving a wringer roll synchronous with the conveying speed of a metal plate to be conveyed in a condition where water is adhered to the plate when water is removed by the wringer roll. SOLUTION: Upper rolls and lower rolls of three sets of wringer rolls 51-53 are driven by one drive device 54, respectively. No slip is generated between either roll and a hot-rolled steel strip by driving both the upper rolls and the lower rolls. When rolls of a three-wringer roll device 5 is driven, the rolls are controlled so that the peripheral velocity of the rolls is synchronous with the conveying speed of the hot-rolled steel strip by a controller. Water is preferably removed from the metal plate at the outlet side of the wringer rolls by blowing a gas at the position of both ends in the width direction of the metal plate from the obverse and reverse surface sides of the meal plate.

Title: Surface treatment
Inventor: YOSHIDA KOUJI
IPC: C23C8/36
Filed: 1978-07-31
Abstract: PURPOSE:To perform stable and sure surface treatment by glow discharge, by setting a workpiece as a cathode for the glow discharge, depositing cations on the workpiece and combining anions with an anode to remove anions. CONSTITUTION:The glow discharge is caused between the electrodes 1, 3 while TiCl4 gas is supplied through a feed port 9 and discharged through an exhaust port 7. At that time, a high-frequency current is caused to flow through a coil 10. The cations of Ti are thus produced and bombarded on the steel workpiece 1 which serves as the cathode. As a result, Ti is coated on the steel 1. The anions of Cl reach the anode 3 and react with the anode metal such as Cu, Mg or Sb capable of easily reacting with Cl. The reaction product is removed from the discharge system. Since ionization is effected by a high-frequency power source separate from a DC power source, the treatment conditions are controlled stable and a high surface treatment effect is produced.

Title: Nonvolatile memory with voltage acceleration function
Inventor: MACHIDA TORU
IPC: H01L29/788
Filed: 1985-04-30
Abstract: PURPOSE:To perform a screening in a short time by connecting a booster output voltage control circuit comprising a voltage limiter with two or more change- over switches to the output of a booster circuit and applying a controlled voltage to a nonvolatile memory element. CONSTITUTION:When a change-over switch 4 is closed and a low voltage limiter 3 is operative, a high voltage generated by a booster circuit 1 is limited to a given value determined by the low voltage limiter 3 and a voltage necessary for normal erase and write is applied to a nonvolatile memory element 7. When a screening is performed, a voltage higher than the one normally restricted to the given value by the low voltage limiter 3 is applied to the nonvolatile memory element 7, although the voltage is limited to another given value determined by a high voltage limiter 5, and therefore a voltage acceleration occurs in the screening, resulting in that defects, such as pinholes, weak spots and the like, existing in the nonvolatile memory element 7 are subjected to the screening in a short time.
