Title: Wiper for car
Inventor: ICHIKAWA KIKUYA
IPC: B60S1/54
Filed: 1983-06-25
Abstract: PURPOSE:To improve the wiping performance by impinging the focused compressed air concentrically against the front glass face and wiping the rain drip through air flow layer to be formed when said air flow disperses/overflows along the glass face. CONSTITUTION:Focused and compressed air flow is injected through a nozzle 1 against the front glass face 2 with proper attack angle. The air flow impinged against the glass face will disperse/overflow along the glass face to form an air flow layer. Said air flow layer will wipe the rain drip and to prevent adhesion of rain drip onto the glass face.

Title: Manufacture of direct heated cathode
Inventor: TSUJI HITOSHI
IPC: H01J9/06
Filed: 1989-05-10
Abstract: PURPOSE:To reduce deterioration of an electrodepositing efficiency in spite of electrodeposition for a long time so as to secure uniform coating by using a bored electrode provided with openings having a minimum diameter of 0.5mmphi or more at an area ratio of 30% or more and 90% or less as a counter electrode with respect to a metallic core wire having a high melting point. CONSTITUTION:A tungsten core wire 3 is brought into contact with an energizing spool 7 by a rotary force of a taking-up spool 10 so as to be snaked in an electrodeposited solution 1 with application of a cathode voltage. And further, the orientation of the core wire 3 is changed by an orientation changing spool 5 so that the core wire 3 is inserted into a bored cylindrical electrode 8 with application of an anode voltage. In this case, since the bored electrode provided with openings having a minimum diameter of 0.5mmphi or more at an area ratio of 30% or more and 90% or less is used as the cylindrical electrode 8 for electrodepositing alkaline earth carbonate particles to a metallic core wire having a high melting point, a convection of the electrodeposited solution can be expedited, and further, the alkaline earth carbonate particles can speedily flow inside the openings. Therefore, a uniform and preferable electrodeposited state can be kept for a long time, and moreover, an electrodeposited wire for a direct heated cathode having a remarkably improved electrodepositing efficiency can be obtained.

Cut sinuous wire rod slides on the rollers of the chute 26 to the tip. Then, an overturning instruction is inputted to an overturning device and the whole chute is overturned temporarily by rotation of a rotation axis 35, and the wire rod 44 is throuwn out to the side of the chute 26.

Title: Mos type field effect transistor
Inventor: SAITOU MITSUCHIKA
IPC: H01L29/78
Filed: 1985-05-29
Abstract: PURPOSE:To make deterioration caused by hot carriers hard to occur by a method wherein the second gate electrode is provided on a thin-doped drain with a thin insulation film in between or directly and the electrode is connected to a source or the drain or a gate. CONSTITUTION:A gate, a source and a drain of an LDD type MOSFET are covered with a thin SiO2 film 5 and a polycrystalline silicon film 6 is deposited on it. The polycrystalline silicon film 6 is connected to the gate 4 through a contact hole drilled in the insulation film 5. The deterioration of the LDD type MOSFET is caused by the phenomenon that carriers are trapped in the insulation film above the thin-doped drain 31 and the number of carriers in the drain is reduced by the trapped carriers. Therefore, if the second gate 6 is provided on the drain and a suitable potential is applied to it, the penetration of the carriers into the insulation film is suppressed and, even if they penetrate and are trapped, they do not cause the reduction of the number of carriers in the drain.

Abstract: PURPOSE:To measure dynamic angles with a high accuracy by making a laser beam incident to an object to be measured by a rotary mirror with an angle detector, detecting the reflected light with a two-dimensional sensor and generating a pulse when the object to be measured and the mirror are parallel.

Title: High-speed logical operation circuit
Inventor: IWAGAMI TAKUYA
IPC: H03K19/0952
Filed: 1979-09-11
Abstract: PURPOSE:To improve the voltage gain between the input and the output practically, by shifting the level of the output signal in the drain electrode of the first GaAsFET by a required quantity and by applying this signal to the gate electrode of the second GaAsFET. CONSTITUTION:When the first GaAsFET starts escaping from the pinch-off state, the voltage of each part is changed. A current is flowed to the first FET, and drain voltage VO1 starts falling slightly, and gate voltage VG2 of the second GaAsFET starts falling. Since the first FET starts operating as a source follower circuit, source voltage VS rises by DELTAV according to rise of gate voltage VG1. Source voltage VS of the second FET falls by DELTAV' also. The current flowed to the first FET is increased to cause drain voltage VD1 to fall from the position of arrow 403 slightly. Voltage VG2 of the second FET falls from the position of arrow 404 slightly also, and voltage VS falls by DELTAV''. By repeating this course, respective voltage values reach a stable point.

Abstract: PURPOSE: To obtain sufficient electrostatic contrast and resolution, when copying the same image by multiple sheets by repeating only development, transfer and fixing, by providing upper and lower layers having a high charge distribution holding capacity across an insulating charge holding layer.  
     CONSTITUTION: A charge holding layer 11, an insulating charge holding layer 2, and a photoconductive layer 3 are laminated on a conductive supporting body 1. First, by primary negative charge simultaneous uniform exposure, the negative charge carrier moves in the layer 3 to reach the boundary of the layers 3, 2. Next, by secondary positive charge simultaneous image exposure, the positive charge carrier reaches the boundary of the layers 3, 2 in the bright part L in the layer 3, and as the counter electrode, the negative charge is injected into the layer 11 from the supporting body 1 and is held in the boundary of the layers 11, 2. Then, by uniform exposure 8, a certain surface potential is caused in the bright part L, while the surface potential of the dark part D is almost zero. In the electrostatic latent image thus formed, a positive charge is held in the boundary of the layer 3 side across the layer 2, and negative charge is injected and held in the boundary of the layer 11 side, thereby providing excellent persistency of the electrostatic latent image.
