Inventor: MATSUDAIRA TSUTOMU
IPC: G06F3/041
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To improve picture quality by lowering the factor of reflection between a touch switch and a liquid crystal display element rather than a conventional case by adhering the display screen of the liquid crystal display element and the rear side of input area of the transparent touch switch through a transparent adhesive agent. SOLUTION: A liquid crystal layer is formed and held between two transparent glass boards 1a and 1b, and a deflection board 2a and a deflection board 2b with reflection board are stuck on the respective transparent boards 1a and 1b. Besides, a driver IC 3 for driving liquid crystal is mounted at the terminal part of the transparent board 1a. On the display screen of that liquid crystal display element, an analog resistant film type touch switch 4 using glass and a film is adhered by a transparent adhesive agent 5. The entire rear side of the input area is coated with the transparent adhesive agent 5 at least.  In this case, when the transparent adhesive agent 5 of refraction factor from 1.47 to 1.57 after hardening, the refraction factor of glass boards 1a and 1b is almost equal with 1.52, the reflection between the touch switch 4 and the liquid crystal display element is almost eliminated and picture quality is improved.

Title: Worm gear device
Inventor: MOCHIZUKI MASANORI
IPC: F16H55/24
Filed: 1990-02-05
Abstract: PURPOSE:To prevent the occurrence of impact sound by providing a guide wall within the locus of the movement of each advancing/retreating tooth which is in a position adjacent to a starting point where a worm tooth is meshed with the aforesaid tooth, but is in a non-meshing condition. CONSTITUTION:Since a guide wall 61 is provided within the locus of the movement of each advancing/retreating tooth 2 which is in a position adjacent to a starting point where the tooth 11 of a worm 1 is meshed with the aforesaid tooth, but is in a non-meshing condition, when each advancing/retreating tooth 2 comes in this section, the tooth section 21 of each advancing/retreating tooth 2 is paired with the guide wall 61. The end section of the guide wall 61 at least at the worm 1 side in a surface faced to each advancing/retreating tooth 2 is set in a position where the tooth section 21 of each advancing/retreating tooth 2 starts meshing. This thereby causes the guide wall 61 to be faced to each advancing/retreating tooth 2 when each advancing/ retreating tooth 2 is moved so as to come to a start pairing point. After that, the advancing/retreating tooth 2 is gradually pushed in, and is finally pushed in a meshing position so that it starts meshing with the tooth 11 of the worm 1. This thereby permits impact sound to be softened when the tooth 11 starts meshing with the advancing/ retreating tooth 2.

Title: Multioutput dc constant current converter
Inventor: YAMAMOTO KATSUHIKO
IPC: H02M3/338
Filed: 1981-02-24
Abstract: PURPOSE:To stabilize the output of a multioutput DC constant current converter in high accuracy and to prevent the influence between the outputs of the converter by connecting an LC series resonance circuit between a plurality of AC output terminals and a rectifying circuit. CONSTITUTION:LC series resonance circuits 37, 38 are connected between a plurality of AC outputs 19, 20 and rectifying circuits 27-30, 31-34. When a transistor 14 is conducted by a drive pulse 13, the transistor 14 is conducted during a period represented by an equation I by a series resonance circuit 37. When a load voltage VA is smaller than the voltage nE of the secondary coil 29 of a transistor 11, a current of reverse direction to that in the previous period is returned through a diode 16 to a DC power source 12 during the period of next pi.(LC)<1/2>, where n represents the ratio of the number of turns of the transformer 11. The switching frequency f of the transistor and the resonance frequency f0 become as equations II. If the input voltage is represented by E, the output current IA becomes IA=8nfCE, wherein 2f<=f0, VA<=nE, and the output current becomes constant irrespective of the load.

Title: Device for lighting up discharge lamp
Inventor: KAWABATA KENJI
IPC: H05B41/392
Filed: 1990-02-07
Abstract: PURPOSE:To improve the ease of use by providing a function of notifying a user of the time immediately before the lamp should be turned off by actuating an appropriate signal issuing means when the flow angle of a dimmer decreases to approach a predetermined value. CONSTITUTION:The flow angle of a phase control dimmer 2 is detected by measuring the time from the point where the voltage waveform on the secondary side of a rectifier 3 crosses a predetermined value to the point of a next crossing. The detected time is digitally processed to determine whether or not the flow angle is in the vicinity of a value B. If a user intends to bring the flow angle to the value C which is for the point immediately before turning off and turns a knob by an amount more than necessary, the flow angle becomes smaller than B and the lamp is turned off, which is inconvenient. To eliminate such a disadvantage, the user is notified of the time immediately before turning off by issuing a sound from a signal issuing means, a sound generator 8 for example, when the range of C is reached.

Abstract: PURPOSE:To obtain a clad ingot, excellent in cleanliness between its plied metal and base metal and small in the variation of clad ratio, by inserting a slab of plied metals having outer surfaces slanted divergently downward, into a mold having opposite inner surfaces slanted so as to expand downward, and pouring a molten base metal into the mold. CONSTITUTION:A built-up slab 11 having outer surfaces slanted divergently downward in approximately the same degree as the slant of the inner surfaces of a mold 3 is inserted into the mold 3 to cast a clad steel ingot by pouring a molten steel 4 into the mold 3 from its bottom. At that time, even when a part of suspended matters 9 existing in the surface of molten steel 4 is included in the boundary surface between the built-up slab 11 and the steel 4 the matters 9 are not left on the boundary surface because the outer surfaces of slab 11 are slanted divergently downward and are tapered upward to make the matters 9 easily floatable. Further, as the thickness of base metal 4 is almost the same through its longitudinal direction, two sheets of one-side clad steel piece obtained by rolling the clad steel ingot are free from the variation of clad ratio.
