Title: Dissolving method of platinum group metal in collector metal
Inventor: AKAHORI MICHIHIRO
IPC: C22B7/00
Filed: 1994-08-09
Abstract: PURPOSE:To efficiently dissolve a platinum group metal in a collector metal by firing the collector metal and heating and dissolving it in hydrochloric acid while adding an oxidizing agent. CONSTITUTION:A hardly soluble waste catalyst powder (collector metal) containing platinum group metal with various impurities is fired at 700-100 deg.C for 2-12hr in closed state. The collector metal is heated and dissolved in the hydrochloric acid by stirring and keeping at 60-100 deg.C for 2-10hr while adding the oxidizing agent (H2O2). In this case, 700-1200ml hydrochloric acid of 35% concn. and 400-700ml H2O2 of 35% concn. per 100g collector metal are used. As a result, the platinum group metal is dissolved at about 87.5% dissolution rate without using a special reagent and repeating complicated processes.

Title: Multilayered ceramic wiring board
Inventor: EZAKI TORU
IPC: H05K3/46
Filed: 1992-07-10
Abstract: PURPOSE:To improve the transverse rupture strength of a low temperature baked multilayered ceramic wiring board composed of glass and crystalline material of the residual part. CONSTITUTION:The thermal expansion coefficient of the outermost layer of a multilayered board is made smaller than that of the inner layer. The total thickness of the outermost surface layer and the outermost rear layer is made larger than the thickness of the inner layer. Thereby the conventional lamination and caking means can be used. On account of the difference of thermal expansion coefficients, compressive stress is generated in the outermost layers, and the transverse rupture strength is remarkably improved.

Abstract: PROBLEM TO BE SOLVED: To generate an output waveform immune to noises by shortening the delay time of an output signal while maintaining a through rate of the output waveform without decrease in a maximum output voltage from the output terminal of a data output circuit. SOLUTION: When a data input line 6 is changed from 'H' level to 'L' level in the 'L' level state of a control signal line 7, a Pch transistor 4 is turned off and an Nch transistor 5 is turned on. In this case, when the rising and falling times of a pulse signal at a pulse generating circuit 10 are defined as T1 and T2, the voltage of an output signal from an output terminal 8 during T1 and T2 sharply drops compared to the through rate of ordinary output signals. After T2, however since an auxiliary transistor 9 is turned off, the ordinary through rate of the said output signal is held.

Filed: 1992-08-03
Abstract: PURPOSE:To form a densely vapor deposited film even on a surface which does not face a target by curving the incident direction of charge particles on a material by means of a magnet in the bias sputtering method. CONSTITUTION:The target 1 to which a DC power source 2 is connected, a rotating table 7 on which a substrate 9 for vapor deposition rides, a revolving table 6 which is connected to a high-frequency power source 4 via a matching circuit 3 and the permanent magnet 8 which is fixed to the revolving table 6 are installed in a vacuum chamber 5. The magnetic field in the radial direction of the revolving table 1 is applied to the substrate 9 for vapor deposition riding on the rotating table 7 and the locus of the Ar ions introduced by the high-frequency power source 4 is curved near the substrate 9 for vapor deposition when bias sputtering is executed by introducing the gaseous Ar constituting the charge particles from an introducing port 10 in this constitution. Since the substrate 9 for vapor deposition exists on the rotating table 7, the surface facing the infiltration direction of the Ar ions changes at all times and the entire periphery of the flank of the substrate 9 for vapor deposition is irradiated with the Ar ions. As a result, the uniform film is formed on the substrate 9 for vapor deposition having level differences and grooves.
