Title: Analysis pretreating instrument and pretreating method using instrument thereof
IPC: G01N1/28
Filed: 1992-03-12
Abstract: PURPOSE:To make it possible to adjust the sample for total-reflection fluorescent X-ray analysis by providing an outer tube having the end part, which can hold the droplet of sample liquid to be analyzed, so as to surround the end part of a capillary, concentrating the sample liquid, and drying and fixing the liquid in a small area at the specified position of a drying plate for the sample liquid to be analyzed. CONSTITUTION:A tip part 3 of a capillary 2 is washed. Sample liquid of about 200mul is sucked into the capillary 2 through the tip part 3. Then, a wafer is set at a specified position and heated to 90-95 deg.C. Then, the tip part 3 of the capillary 2, which has sucked the sample liquid, is moved to the specified position on the wafer. The tip part 3 is lowered to a specified interval for the wafer, and the sample liquid is discharged slowly. A small droplet is formed between the tip part 3 and the wafer. The diameter of the droplet becomes constant by adjusting the discharging speed of the liquid and the evaporating speed by heating. For example, when the discharging speed is be made to about 10mul/minute at the surface temperature of about 90-95 deg.C, the diameter of the droplet becomes about 2mm. The droplet is dried and fixed in the intact state. Thus, the sample liquid of the large amount of liquid can be dried and fixed in the minute area at the set position of a dying plate.

IPC: B23K35/02
Filed: 1989-04-07
Abstract: PURPOSE:To allow this electrode to have a long service life by forming an electroless plating layer containing titanium and beryllium on the surface of an electrode body made of a copper alloy. CONSTITUTION:An electroless plating layer 3 is formed on the surface of the outside of an electrode body 1 of a cap tip electrode for resistance welding made of chrome copper. This electroless plating layer 3 contains titanium and beryllium, and at the time of forming this plating layer 3, the electrode body 1 made of a chrome copper alloy is brought to pre-treatment by using a pre- treatment liquid whose main component is sulfuric acid, and thereafter, immersed into an electroless plating liquid containing beryllium acetate, second titanium sulfate, hyposodium sulfate, and sodium thiosulfate. In such a way, even in the case this electrode is used for welding of a zinc steel plate, zinc is scarcely transferred to the surface of the electrode, and the electric conduction failure is prevented completely. Also, the electrode can have a long service life since its hardness is large.

Title: Copper alloy for commutator
Inventor: MIYATOU MOTOHISA
IPC: C22C9/00
Filed: 1981-06-09
Abstract: PURPOSE: To obtain a copper alloy which is inexpensive and can extend the life of carbon brushes by contg. specific amts. of iron and phosphorus in lieu of silver in copper.  
     CONSTITUTION: An alloy consisting of 0.02W0.5wt% Fe, 0.02W0.1wt% P and the balance Cu and impurities. Here, Fe and P alone have a low effect of improving strength and heat resistance, and result in degreaded conductivity; therefore, the coexisting of both is necessary. If the Fe is below the lower limit, the improvement in strength and heat resistance is not expected despite the containing of P, and results in degraded abrasion resistance. In excess of the upper limit, work hardening increases considerably and there is a problem in production. If the P is below the lower limit, there is no effect of improving strength despite the coexistence with Fe and in excess of the upper limit, the P that solutionizes into the Cu matrix increases, thus resulting in considerably degraded conductivity.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To allow stains damaging beautiful appearance and causing rusting hard to deposit on the steel sheet by providing it with only waviness to form into the basis of ruggedness in a dull finish as the ruggedness on the surface. SOLUTION: On the surface of a stainless steel sheet, only waviness of form into the basis of ruggedness in a dull finish is left, and the other fine ruggedness is removed. The waviness to form into the basis of ruggedness in a dull finish denotes the smooth and curvy one imparting roughness of 1.5 to 3.5 μm average roughness Ra and 8 to 30 μm maximum roughness Rmas and does not include fine waviness of one figure or smaller than that superposed thereon. For removing the fine waviness, polishing such as electrolytic polishing is executed. By removing fine waviness, while the facilitation of peeling stains caused by ruggedness as the advantage of dull-finished steel sheet is maintained, the remaining of stains and salt caused by the fine ruggedness can be prevented, by which stains, rusting, or the like, is not generated on the stainless steel sheet over a long period.

Title: High efficient coder for picture data
Inventor: KAGEYAMA KOJI
IPC: H04N19/196
Filed: 1990-04-04
Abstract: PURPOSE:To attain high compression rate by applying prediction coding to a low frequency coefficient data obtained through orthogonal transformation such as DCT for each small block through the use of a coefficient data of other small block. CONSTITUTION:A coefficient data obtained by an orthogonal transformation circuit 4 is quantized again by a re-quantizing circuit 5. Coefficient data of each small block in the output of the requantizing circuit 5 are divided into low frequency and high frequency data while taking a border as Bd. At least, the coefficient data of the lower frequency side of at least one small block is prediction-coded by using other small block. Thus, high compression rate is attained through the hybrid constitution of the orthogonal transformation coding and the prediction coding.
