SiO2 on the surface of a wafer is dissolved with hydrofluoric acid for removal and washed clean, then boron is thermally diffused over a silicon surface, making platelike Pyrex glass 8 stick to the backside of the wafer, and both sides of the wafer are cut off. A ball spacer 13 and a silicon rod assembly are placed on each wedgelike groove of both holding parts 11 and 12 stuck to this Pyrex glass 8, and upper and lower Pyrex glass parts are locked so as not to move with each other. Therefore, a ratio of errors in the opposed electrode interval can be made yet smakker, so that an electrode and the electrode interval comes easy for miniaturization as far as a portion for that.

Title: Residual chlorine meter
Inventor: MATSUMOTO TETSURO
IPC: G01N27/416
Filed: 1984-08-28
Abstract: PURPOSE:To enable accurate measurement of isolated chlorine, by mixing a specified buffer reagent into a solution to be measured at a fixed ratio while a fixed voltage is applied between an indicator pole comprising a rotary platinum electrode and an opposed pole comprising a silver bromide electrode. CONSTITUTION:Feed pumps 2a and 2b are driven, a buffer reagent in a tank 1 and a liquid to be measured in a tank 3 are fed and mixed together at a fixed ratio, for example, 3:100 to be fed to a measuring container 4. When an isolated chlorine such as Cl2 and a bond chlorine such as NH2Cl coexist in the liquid being measured, as potassium bromide KBr is added to the liquid being measured, a reaction is caused according to a specified formula. This reaction will be promoted as the pH value of the reaction liquid is inclined to the acid range to form more Br2. Thus, the pH value of the buffer reagent shall be controlled to about 6.0. When Br2 is reduced with an indicator pole 6 comprising a rotary platinum electrode, a reduction current flows between the indicator pole 6 and an opposed pole 7 comprising a silver bromide and detected with a galvanometer 9 to determine the amount of the isolated chlorine from the current value detected.

Filed: 1990-07-06
Abstract: PURPOSE:To improve heat dissipation effect even in a narrow space where a blower can not be installed, by a method wherein a piezoelectric fan is constituted by sticking a piezoelectric member on the base part of a substrate, and the tip part of the substrate functions as a blade capable of vibration. CONSTITUTION:When an AC voltage is applied across a substrate 20 of a piezoelectric fan 15 and piezoelectric ceramics 21, the piezoelectric ceramics 21 expands and contracts, and the substrate 20 continues bending motion in the axial direction of a heat introducing part 14. As the result of the bending motion of the substrate 20, a blade 22 vibrates. The vibration frequency of the blade 22 coincides with the frequency of the above AC voltage, which frequency is nearly equal to the frequency of natural mode of vibration of the blade 22. Hence the blade 22 resonates and generates large vibration. By the vibration of the blade 22, the air flow shown by arrow A is formed in the vicinity of the blade 22 of each piezoelectric fan 15. The air flow is uniformly generated in the blade 22 of each piezoelectric fun 15, and the flow velocity becomes about 2-3m/s. Thereby excellent effect of heat dissipation can be obtained.

Title: Video signal transmission method/device, video recording device/method and signal converter
Inventor: KORI TERUHIKO
IPC: H04N5/915
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent duplication in the case of transmitting and recording an analog RGB signal. SOLUTION: A copy prevention signal consisting of a pseudo synchronizing signal and an AGC pulse is superimposed in a plurality of horizontal scanning periods with a prescribed number in a vertical blanking period of a signal G from an input terminal 1G. An AGC gain detector 3 detects an amplitude from a SYNC tip of the pseudo synchronizing signal upto a peak of the AGC pulse as an AGC gain, and controls gains of AGC amplifiers 2R, 2G, 2B based on the result of detection. The peak of the AGC pulse is made much larger than the pedestal level. Thus, the gain of the AGC amplifiers is reduced to significantly reduce the amplitude of the RGB signal. Thus, the normal video recording cannot be made.

Title: Wiring pattern
Inventor: HIROI MASAKI
IPC: H01L21/3205
Filed: 1988-07-19
Abstract: PURPOSE:To prevent disconnection and to improve reliability by making line widths of a wiring pattern at a lower potential are larger than ones at a higher potential. CONSTITUTION:A wiring pattern 3 in which the line width of a lower potential is larger than that of a higher potential is provided. According to such a pattern 3, a disconnection does not occur even after an electromigration generated upon movement of a wiring material from a lower potential to a higher potential since the supply of the material is large near the position L of lower potential. An arrow shows the electromigration movement. When the line width of the higher potential is excessively thin than that of the lower potential, the moved material is raised to be possibly disconnected. Accordingly, the ratio of the line width of higher voltage to lower voltage is desirably ranged A:B at 1:1.1-1:10 and more preferably A:B=1.1.5-1.2 approximately.
