Inventor: SAKAI CHIAKI
IPC: H01J1/304
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To substantially eliminate a defective element by placing an element with electron emission parts and gate electrodes formed on a support body, in an oxidizing atmosphere, and applying voltage between the electron emission parts and gate electrodes. SOLUTION: A cold cathode field electron emission element with electron emission electrodes 26 and gate electrodes 24 formed on a support body 21 is placed in an oxidizing atmosphere, and voltage is applied between the gate electrodes 24 and a cathode electrode 22 to which the electron emission electrodes 26 are connected. In the element with a short-circuited state between the electron emission electrodes 26 and gate electrodes 24, the electron emission electrodes 26 and/or gate electrodes 24 generate heat as a result of current flow and are oxidized and put in a nonconductive state. The short-circuited state between the electron emission electrodes 26 and gate electrodes 24 is thereby dissolved to substantially eliminate a defective part. This avoids a problem of failing to completely display the entire row of a striped electron emission area row including the element.

Title: Dimming method for copying machine
Inventor: SHIBUSAWA MITSUO
IPC: G03B27/54
Filed: 1987-06-12
Abstract: PURPOSE:To easily adjust exposure at the time of copying originals by controlling the passing angle of AC to be supplied to an exposure light source. CONSTITUTION:Variable resistors VR1, VR2 to be phase adjusting elements to be operated from the surface of an operation panel are connected to each other in series and constitute a dimming means together with an automatic voltage adjuster 1. When the maximum resistance value of the resistor VR1 is set up higher than that of the resistor VR2 and the resistor VR2 is set up to its maximum value at the initial stage of using of a copying machine, the passing angle to be varied by the resistor VR1 is t2-t4 e.g. as shown by a waveform in Fig.(b). The change width of exposure of the passing angle t2-t4 is allowed to correspond to all kinds of originals. When the copying machine is used for a long period, light quantity on a photosensitive body starts to be lacking. At that time the exposure can be easily increased by gradually approaching the resistor VR2 to zero and shifting the passing angle in the increasing direction from t1 to t3.

Title: Laminated leaf spring
Inventor: YAMAMOTO EIJI
IPC: F16F3/02
Filed: 1990-06-05
Abstract: PURPOSE:To improve riding comfortableness relating to both large and small amplitudes by extending a child leaf, adjacent to a main leaf having a dome- shaped eye, to the outside of a load point of the main leaf and forming a shape of a contact part with the main leaf into a cycloidal curve with an external diameter of the eye serving as a basic circle. CONSTITUTION:A laminated leaf spring is constituted of a main leaf 1, having a dome-shaped eye 4, and child leaves 2, 3, and the second child leaf 2, adjacent to the first main leaf 1, is formed in a span of a load point or more of the main leaf 1. A lower surface of the eye 4 is brought into contact with an upper surface of the child leaf 2 in a contact point TP. A leaf surface CS of cycloidal curvature with an external diameter R of the eye 4 serving as a basic circle is formed by a contact surface formed by the contact point TP. Thus, rolling friction is obtained without generating slip friction in small amplitude and a diagonal spring constant is prevented from decreasing by generating the slip friction in large amplitude. Accordingly, riding comfortableness of a vehicle is improved in both regions of large and small amplitude.

Title: Immediate effective itching removing device
Inventor: MIYAZAKI KAZUNORI
IPC: A61N5/06
Filed: 1993-05-12
Abstract: PURPOSE:To break the balance of a stimulus to feel itchy and eliminate an itching by applying heat to the itchy point of a skin surface. CONSTITUTION:The heat 2 is applied to the itchy point 1 of the skin surface. The itchy part does not burn but senses the transfer of the heat after a while and the itching disappears when the heat of a cigarette lighter is instantaneously brought near to the itch point. The same holds true even with heating by IR rays. Combustion gases, steam, IR rays, etc., are usable. The human body has sense organs to sense a pain, etc., but the sense organs to sense the itching do not exist therein. The balance of the stimulus that the sense organs receive is, therefore, considered to act largely. The heat is used to break the balance of the itching. The heat has an effect of removing the itching and has the rapid action to remove the itching.
