Abstract: PURPOSE:To display articles so that they can easily be taken out and to effectively prevent robbery by advancing an array of articles each time an article is taken out and generating an electronic tone of melody, etc., as an alarm tone when the article is taken out. CONSTITUTION:An energizing mechanism 3 which moves the whole array of packs of cigarettes C forward with the energizing force of a spring 8 when the foremost pack of cigarettes C is taken out, makes a following pack of cigarettes C ride on a slanting surface part 12 and project, and also brings this pack of cigarettes C into contact with a stopper member 11 to stop the array of packs of cigarettes C from advancing. Thus, the pack of cigarettes C is always present at the front end part of this article holding part and the pack at the foremost end projects upward, so the pack can easily be taken out. When the foremost pack C is taken out, the signal outputted from an optical detector 14 is sent to an alarm generation part through an electric conductor 15 and this alarm generation part generates the electronic tone of melody, etc., as the alarm tone.

IPC: H01L29/80
Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To decrease the gate voltage of a control transistor in proportion to an AGC potential, and to reduce a voltage by providing a prescribed circuit constitution by using dual FET for both a main transistor and the transistor for controlling a gain. SOLUTION: A common part 21 of transistors TC1 and TC2 of a control transistor Q2 in a dual gate structure is connected through a resistor R2 with a gate G1 of a main body transistor Q1, and a gate G2 of the main transistor Q1 is connected with a gate 1 of the control transistor Q2. When an AGC potential is impressed to the gate G2, the voltage of the gate G1 of the control transistor Q2 is decreased according as the AGC potential is decreased, and currents running through the control transistor Q2 are decreased, and a potential VC of the common part 21 is increased according to the decrease of a voltage. As a result, a voltage is supplied to the gate G1 of the main transistor Q1 so that the function of a forward AGC function can be obtained.  Thus, the voltage of the gate 1 of the control transistor is decreased in proportion to the decrease of the AGC potential so that distortion characteristics at the time of attenuating a gain can be improved.

Title: Electrode plate in ion source
Inventor: ICHIHASHI KOJI
IPC: G21B1/00
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To obtain a long-life electrode plate by bonding a corrosion-resistant metal on each surface of two thin sheets made of a highly thermal-conductive material after forming a film and jointing a bush made of the corrosion-resistant metal near an entrance and an exit for the cooling water. SOLUTION: A molybdenum thin sheet 3a where cooling gutters 2 are formed is jointed with a thin sheet 3b through a titanium film 21 formed over the whole area on the joint surface side. Moreover, films 21 are formed on the joint surface of a molybdenum header 4 at a cooling water inlet and on the inner face of a communicating hole 4b. A titanium bush 22 is jointed with the part near a penetrating hole 4a in the header 4, and a gasket 12 is evaporated onto the upper face of a flange part 22a formed near the upper end of the bush 22. Since the cooling water passages of these electrode plates are covered with corrosion-resistant titanium to keep molybdenum out of contact directly with the cooling water, the corrosion of the electrode plates can be reduced.  In addition, the installation of the gasket 12 on the bush 22 side prevents the cooling water from going into interstices between an installation flange 9 and the header 4 to reduce the corrosion caused by the cooling water. This is also true for the cooling water outlet header side. Consequently, long-life electrode plates can be obtained.

Abstract: PURPOSE:To enhance steel material resistance to heat and corrosion in an extremely simply manner by a method wherein Al is preliminarily diffused into the surface of steel material to form solid solution, then solid Al is rubbed into the surface while removing oxide layer at a high temperature. CONSTITUTION:Al is diffused into the surface of steel material to form solid solution by use of diffusion penetration process. Then, from the surface of steel material, surface oxide is removed by mechanical means such as wire brushing or grinder abrasion at temperature of 600-800 deg.C. Immediately, at this temperature, solid Al is rubbed into the surface having diffused Al solid solution, so that Al is melted to form Al layer that enhances the steel material resistance to heat and corrosion. In this case, Al layer may be further heated to form secondary diffusion layer, so that Fe-Al intermetallic compound may be formed.
