Accordingly, a magnetic field Hca in the case wherein the level of the magnetic field strength is reaches while it is increasing is different from that in the case wherein the level is reaches while the strength is decreasing for each level of the magnetic field strength acting on a magnetic detector 1. Thus, the magnetic detector 1 itself has the characteristic of hysteresis.

IPC: H03M11/02
Filed: 1982-04-30
Abstract: PURPOSE:To perform an accurate detection of coordinates, by using a semiconductor switching circuit which conducts in both directions to an AC signal to ground all electrodes excluding the selected electrode and therefore eliminating an effect due to the variance of the floating capacity. CONSTITUTION:Electrode lines Xn and Yn are connected in parallel to a detecting panel PN to form a contact part TCH of a touch electrode. A counter 5 transmits a switch signal to a changeover switch 3 with the signal of a clock 4, and touch electrodes are successively selected A1-A8. While the switches excluding those corresponding to the selected electrodes are grounded among switches S1-S8 in response to the selection of the switch 3 and via a decoder 6. A switch SC is formed by combining semiconductor switching elements which have a bidirectional switching action to an AC signal of both positive and negative polarities of an oscillator. As a result, it is possible to compensate the effect of variance of the floating capacities of the lines Xn and Yn. This process unifies the capacity which is connected to a coexisting circuit 1 and can obtain an even detecting level. Thus the coordinates can be correctly detected.

IPC: C23C14/08
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a transparent conductive film having reduction resistance, translucency and conductivity, and useful for an anode conductor for a FED. SOLUTION: As for this transparent conductive film, the enclosure 2 of a FED 1 comprises a cathode base 3 and an anode base 4. There is an anode 7 comprising an anode conductor 5 and a phosphor layer 6 on the inner surface of the anode base 4. The anode conductor 5 comprises a first layer 8 of ITO being in contact with the inner surface of the anode base 4 and a second layer 9 of ZnO:Al. Since ZnO has translucency and conductivity, and is also stable as an oxide, it is not easily reducible (reduction resistance) even in a reductive atmosphere. It is excellent in particular in translucency and conductivity because of a proper amount of Al added. A field emission element 10 is provided on the inner surface of the cathode base 3 as a cathode serving as an electron source. The ITO easily reducible is coated and protected by the second layer 9 of a thin Al film.  Even if the inside of the enclosure is kept in a reductive atmosphere in a manufacturing process of the FED, no disadvantage of depositing In by reduction of the ITO of the anode conductor is caused.

Title: Pretreatment of cold rolled stainless steeel strip before annealing
Inventor: ISHIKAWA MASAAKI
IPC: C21D9/52
Filed: 1984-04-13
Abstract: PURPOSE:To facilitate the descaling of a cold rolled stainless steel strip at a low cost and to improve the surface properties of the strip by applying an aqueous soln. of a specified alkaline substance having a prescribed concn. to the steel strip before the strip is continuously annealed and descaled. CONSTITUTION:Rolling oil sticking to the surfaces of a cold rolled stainless steel strip is removed with a suitable degreasing agent. An aqueous soln. of KOH or Ca(OH)2 adjusted to 9-13pH is applied to the surfaces of the degreased strip, and the strip is continuously annealed. Even when the strip is annealed in a conventional oxidizing atmosphere, the formation of oxide scale can be effectively inhibited. The annealed strip is descaled by a known method. Since the strip can be easily descaled by said pretreatment before annealing, the quantity of electric power required to descale the strip by electrolysis and the concn. and temp. of an acid soln. used can be reduced, and the surface luster after descaling can be improved.
