Title: Pretreatment for vacuum deposition
Inventor: KIMURA SADAHIKO
IPC: C23C14/02
Filed: 1986-12-02
Abstract: PURPOSE:To subject the surface of a metallic strip to a pretreatment suitable for vacuum deposition by subjecting the degreased and pickled strip further to pickling and plating treatments in the same treatment bath prior to formation of various films by vacuum deposition of the surfaces of the metallic strip. CONSTITUTION:The surfaces of the metallic strip are pretreated to clean the surfaces and to improve the adhesiveness of vacuum deposited film at the time of forming the films of metals, etc. on the surface of said strip by a vacuum deposition method. Since the degreased and pickled strip 1 is thereby oxidized in the air and the oxide films are formed thereon, the strip is passed in an electroplating liquid cell 2 contg. the bath of the hydrochloric acid or sulfuric acid system to provide the similar effect as the effect of ordinary pickling. Plural electrodes 3a, 3b are provided above and below the strip 1 in the cell 2 and a negative electrode is impressed on the electrodes 3a to dissolve away the oxide films on the surface of the strip in the position opposite to said electrodes. A position potential is impressed on the electrodes 3b to form the thin plating layers having the good fit to the metal to be deposited by evaporation in the ensuing stage on the surface of the strip. Such strip is rinsed in a rinsing tank 9, is dried 10 and is conveyed to a vacuum deposition device.

Patent JP-H04161721-A (JP)
Title: Flame detector
Inventor: HIJIKATA YASUHIRO
IPC: F23N5/08
Filed: 1990-10-26
Abstract: PURPOSE:To stabilize the detection of flames and fain high reliability by connecting a capacitor with a photodiode of a flame detector in series. CONSTITUTION:When there is no incident light on a flame detector, a photodiode SPD operates on an operation curve (a). When the amount of incidence of the photodiode turns to gamma after it is ignited, it moves from the operation curve (a) to an operation curve (c). Since a forward bias voltage remains as it is Va(V), it moves from an operation point 1 to an operation point 2 where optical current flows in the photodiode SPD until a charging voltage of a capacitor C turns to Vc(V) and operates on the operation curve (c). When the incident luminous energy is fluctuated between beta and gamma by the flickering of flames, optical current if flows, responding to the change. The output voltage of an arithmetic operation amplifier A is represented by eo (t)=Rfit(t) where (Rf stands for a resistant value of a feedback resistor Rf). Only the voltage of a flickering frequency characteristic of each fire is arranged to pass by the application of a band pass filter B and enters the voltage into a decision circuit D where specified value is set and the presence of flames is decided.
