CONSTITUTION: In this method, a material to be coated is subjected to electrodeposition coating by using a cationic electrodeposition coating material contg. a rust preventive pigment such as positively charged Pb. At this time, before performing the electrodeposition coating, the material to be coated is immersed in UF treatment liquid permeate or RO liquid concentrate of the cationic coating material beforehand and current is passed through the UF permeate or RO concentrate for about 1 to 3min with the material to be coated as the cathode by applying an about 50 to 300V voltage between an anode and the cathode to deposit Pb as the rust preventive pigment on the material to be coated. Subsequently, the resulting material to be coated in a wet state as it is, is subjected to conventional cationic electrodeposition coating.  Then, the unelectrodeposited coating material is washed out with water and thereafter, the formed coating film is baked and hardened.

Filed: 1985-03-13
Abstract: PURPOSE:To replace gold with other metal such as copper while insuring weldability and neck strength of a ball by a method wherein an alternating voltage which gives larger energy when a metal wire is positive than when the wire is negative is applied between the metal wire and a discharge electrode. CONSTITUTION:An alternating voltage is applied between a metal wire 1 and a discharge electrode 2. If the value V1 of the voltage applied when the metal wire 1 is positive is larger than the value V2 of the voltage applied when the metal wire 1 is negative, an arc 3 is formed between the tip of the metal wire 1 and the discharge electrode 2 and concentrated heat is given to the tip of the wire 1. On the other hand, when the wire is negative, the arc 3 is formed extending to the top part of the metal wire 1 and the heat is given to the wire through the surface skin of the wire surface. With this process, the heat supply phenomenon is repeated so that the tip of the wire 1 is turned into a ball 28 the main part of which has perfect melting hysteresis and little unmelted part is left at the neck part 28a.

Title: Weight measuring method
Inventor: INOUE SHINICHI
IPC: G01G3/16
Filed: 1987-03-03
Abstract: PURPOSE:To speedily and accurately measure the weight of an object body by determining an arithmetic section according to the maximum and minimum values of measured time-series data, and averaging data in this arithmetic section and finding a weight estimate value. CONSTITUTION:A weight signal obtained by a weigher 3 is converted by an A/D converter 8 into a time-series digital signal, which is recorded in a time- series unprocessed data memory 93. A CPU 92 calculates a reference value from the maximum and minimum values in a specific section of said time-series unprocessed data. Then this reference value is compared with the time-series data to find the start point and end point of the time-series data. Data in the section between those start and end points are integrated to find the total value, which is averaged by said section to perform weight estimation operation. The weight value of the weighed body is calculated from this weight estimated value. Consequently, the weight of the object body is accurately measured before the elastic body of the measuring instrument enters a steady state.

IPC: A61B1/06
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To eliminate abnormal rise in the internal pressure of a light source unit in case of the generation of a gas from a battery by providing a relief valve to escape a pressure in a battery chamber part when the pressure rises therein in the light source unit which has a light source lamp and the battery airtight by built thereinto. SOLUTION: A V groove 71 is formed near the front end of a battery chamber case 31 forming an external wall of a battery chamber part 30b to encircle the external surface of the battery chamber case 31 and a communication hole 72 is bored in the battery chamber case 31 for communication between the bottom part of the V groove 71 and the inside of the battery chamber part 30b. An O ring 73 is fitted into the V groove 71 from outside to block the infiltration of water or the like into the battery chamber case 31 from outside. At this point, as the air pressure in the battery chamber part 30b rises above a fixed value, a high pressure gas in the battery chamber part 30b passes through the communication hole 72 and forces the O ring 73 to be expanded outward so that the gas is released outside.  Thus, when the air pressure in the battery chamber part 30b falls below the fixed value, the O ring 73 returns to the normal position where the V groove 71 is tightened again.
