Filed: 1985-07-23
Abstract: PURPOSE:To evade the loss of expensive silver and to plate highly precisely at high speed by dipping a base material of copper (alloy) which is baser than silver and a copper-plated base material in a pretreating soln. contg. a cyclic compd. having a thioureylene group in the ring and then plating silver with a silver plating soln. contg. the compd. CONSTITUTION:Various electronic parts having surfaces of metals baser than silver such as copper, a copper alloy and a copper-plated base material are washed, degreased and then dipped in the above-mentioned pretreating soln. A soln. contg. the compd. shown by the formula, having a 5- or 4-membered ring and contg. C and N as the other component atoms of the ring is preferably used as the pretreating soln. As the cyclic compd., 2-imidazolidinethione can be exemplified. Silver is plated on the material to be treated which has been dipped in the pretreating soln. by using a high-speed silver-plating soln. contg. alkali cyano silver and the cyclic compd. and passing an electric current. The obtained silver-plated film has excellent adhesion and high hardness and is uniform and smooth, and hence the film is most appropriately used as the silver plating of electronic parts.

Title: Manufacture of saw blade of coated belt
Inventor: SAKAI HIDEHIKO
IPC: B23D63/00
Filed: 1989-06-27
Abstract: PURPOSE:To improve the cutting performance by coating a rigid coating material to a saw blade belt by vacuum arc evaporator prior to hardening and tempering, and applying a heat process so as to improve attachment force of the coating material to the saw blade belt. CONSTITUTION:Before applying a heat process to harden a blade tip, a rigid coating material 9 of 1-5mum is applied to a tooth part 3 and a truck part 5 of a belt saw blade 1 by use of a vacuum arc evaporator. That is, the material is put in a vacuum chamber, a negative voltage is applied to the material, and the vacuum evaporator is actuated, so titanium ions accelerated by the negative voltage make an impact to the belt saw blade 1 to clean the surface of the blade tip. The potential is then decreased, nitrogen is introduced, and a rigid coating material 9 such as titanium nitride is deposited for coating. A heat process of hardening and tempering is then applied at a little higher temperature than a normal hardening temperature. Because of existence of the coating material, high speed steel of the base material will not be oxidized, and attachment force between the coating material 9 and the belt saw blade 1 is improved by the high temperature heat process, thereby abrasion resistance is improved, and the cutting resistance is improved.

Title: Testing device for analog-digital converter
Inventor: TSUJIMURA HIDEYUKI
IPC: G01R31/00
Filed: 1981-10-13
Abstract: PURPOSE:To perform a test for numbers of items in a short time, by obtaining with high accuracy the threshold value to the digital output code of an A/D converter and storing the data of obtained threshold value. CONSTITUTION:An A/D converter C to be tested receives the digital signal of a counter A which counts the clocks and digitizes the analog output signal given from a D/A converter B having a larger number of bits than the converter C. This digital signal is fed to a comparator E directly or via a temporary storage circuit D. The comparator E delivers an output every time the output code of the converter C varies. The output codes of both the counter A and the converter C of that moment are stored in the storage circuits M1 and M2. Thus the circuit M1 stores with high accuracy the threshold value to the changing point of the converter C. A processor CPU reads and processes the codes stored in the circuits M1 and M2. In such a way, the various functions of the converter C can be tested with high accuracy and at a high speed.
