IPC: C25D21/14
Filed: 1980-12-03
Abstract: PURPOSE: To improve durability of through-hole plating against thermal impact by preelectrolyzing a replenishing anode material in a copper sulfate plating bath at a specific chlorine ion concn. in the presence of a brightener used in the regular plating bath and forming a synthetic film then using the same.  
     CONSTITUTION: At the state of replenishing a copper anode material contg. phosphorus in a coppe sulfate plating bath, the replenishing anode material is preelectrolyzed in the copper sulfate plating bath at 5W50mg/l chlorine ion concns. in the presence of the brightener used in regular plating bath. The synthetic film of a blackish brown color consisting of copper, phosphorus and org. material is formed on the fresh surface of the anode material. If the anode  material stuck with such synthetic film is replenished in the copper sulfate plating bath, the brightener concn. in the plating bath is properly controlled and the  through-hole plating of high reliability is obtained.

Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To enable the display of the stereoscopic vision of the surface geometries of a sample so that the surface geometries of the sample may be stereoscopically observable in a scanning probe microscope. SOLUTION: The stereoscopic data of the surface geometries of a sample is obtained by a scanning probe microscope (step S1). The obtained 3-D data is transformed into not less than two 2-D data obtained by views from different directions of lines of sight according to predetermined parallactic angles (step S3). The location of display at the time of displaying the not less than two transformed 2-D data on a screen are determined according to the parallactic angles (step S5). And then these 2-D data are displayed at the location of display (step S6). By locating eyes on the lines of sight by the parallactic angles to the image displayed by a displaying method and looking at the image of each direction of the line of sight, an image equivalent to the image at the time of observing the 3-d sample is formed in the eyes to enable the stereoscopic view of the sample.

Filed: 1990-06-29
Abstract: PURPOSE:To put the optical oscillator in operation by applying constant-voltage by branching modulated bias light into output light and control light which is made incident on a photoelectric converting means through a specific optical path. CONSTITUTION:When stationary bias light Pbias is inputted from an optical fiber F1 to an optical modulation part through an optical fiber coupler FC1, the bias light modulated by the optical modulation part is reflected by a high reflecting mirror part and then made incident on an optical fiber coupler FC2 from the optical fiber coupler FC1 through an optical fiber F3, so that the light is branched into the output light and control light. Further, the control light is delayed by an optical time by passing through an optical fiber F4, then fed back to a photodetection part from an optical fiber coupler FC2. Consequently, external electric control is required and the optical oscillator can operate with a constant voltage power source.

Title: Device for detecting refrigerant deficiency
Inventor: MATSUO HIROKI
IPC: F25B49/02
Filed: 1990-06-28
Abstract: PURPOSE:To enable accurately detecting deficiency of the refrigerant independent of the magnitude of the load on a refrigeration cycle by a method wherein, when the refrigerant circulating in the refrigeration cycle is judged to be deficient by the detection of a refrigerant dryness exceeding a specified value, a means for compensating the specified value functioning in a linkage with the load on the refrigeration cycle compensates the specified value. CONSTITUTION:When the circulating refrigerant falls short in quantity, the volume of its gaseous component in a gas-liquid separation chamber 21 increases whereas the volume of its liquid component therein decreases, so that the level of the liquid declines. When the dryness x of the refrigerant increases over a specified dryness Xo, the refrigerant in a gaseous state flows not only through an upper discharge channel 25 but also through a lower discharge channel 26 and a float 31 sinks to the bottom wall 22 of the gas-liquid separation chamber 21. As a result, a magnet 33 fitted on the float 31 acts to turn on a lead switch 32, which then inputs an ON signal to a controller l and causes a warning lamp 34 to be lighted.
