Title: Surface acoustic wave filter device
Inventor: KURODA YASUSHI
IPC: H03H9/25
Filed: 1994-08-25
Abstract: PURPOSE: To give a high selectivity and a high out-of-band attenuation by preventing the bonding wire to be connected with a bonding pad from existing on the upper part of the area of an interdigital transformer. CONSTITUTION: The bonding pads 3 and 4 provided between the resonator filters connected in two steps are provided between opposed reflectors Gr 7, Gr 8 and Gr 7a, Gr 8a.

Abstract: PURPOSE:To improve the efficiency of a soldering inspection and reliability by forming at least one of a component disposition diagram and a double resist of ink in which substance for discoloring or coloring by heat, ultraviolet ray or electron beam is added as a coloring material. CONSTITUTION:Since ink for a component disposition diagram 14 and a double resist 15 contains substance for discoloring or coloring by heat, ultraviolet ray or electron beam to be added as a coloring material, it is, for example, black in a normal state, but if it is heated to 35 deg.C or higher, #27 (Fast Black) is discolored to become white by titanium white. Here, the #27 may include, in addition to the Fast Black, green, grown, blue, etc. When the ink is used, since it is black in a normal state, the resist 15 can be distinguished from solder 16 by pattern recognizing by using a monochromatic camera. If the diagram 14 is confirmed, it is heated to 35 deg.C or higher, the diagram 14 thus becomes white, thereby improving its visibility.

IPC: F16K17/36
Filed: 1981-12-14
Abstract: PURPOSE:To prevent the device from malfunctioning under usual conditions and yet  enable to shut off gas passage under seismic conditions by a structure wherein a metal  ball made of ferromagnetic material is attracted to the bottom of a magnet and, when  the metal ball is separated from the magnet due to external shock or vibration, a  valve is sprung up, causing to close a valve seat. CONSTITUTION:When the metal ball 1 attracted to the bottom of a bar magnet 3 is  separated from the bottom due to the shock or vibration generated by earthquake or  the like, the bar magnet 3 located above a magnet resting plate 2 repels an annular  magnet 4 and springs up together with the valve 5 provided above the magnet 3 so  as to fix to the valve seat 6, resulting in shutting-off the gas passage. In order to reset  the device after the actuation of subject mechanism, a reset handle 11 arranged at the  upper part of a main body 10 is turned fully clockwise and set free. After that, the  reset handle is back to its original position by being assisted with a return spring and  the pressure of gas. At this time, a reset shaft 12 is turned together with the reset  handle 11 and lowered by means of a guide screw 13 so as to push down the valve 5.  Because the valve 5 is pushed down together with the bar magnet 3, the valve 5 is  reset by the attraction of the metal ball 1 to the bottom of the bar magnet 3.

Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To carry out pattern formation without using a mask and lower the cost by providing fine spherical bodies randomly in a pattern on a dielectric layer formed on a silicon layer. SOLUTION: A silicon layer 810 is formed on a glass or quartz substrate 800 by deposition and oxidized to form an oxide dielectric body 820 layer. Fine spherical bodies 830 are deposited in a randomly separated pattern on the dielectric layer. Further, the pattern of the fine spherical bodies 830 is transferred to the dielectric body 820 by anisotropic etching method to form island parts. Emitters 812 having sharp tip parts are formed at the positions where the island parts exist are formed by etching and deposition steps to give a display structure body. The structure body however is not a strictly geometric array but consists emitters at random intervals. In this way, without using a mask, self-aligned pattern formation with high density can be carried out and the cost is lowered.
