Title: Method for soldering semiconductor element
Inventor: JIMI EIJI
IPC: H01L21/58
Filed: 1983-05-31
Abstract: PURPOSE:To obtain the good binding properties with evenness and cleanness by using the sheet material on a surface of which a coating layer consisting of active carbon and polyimide-group heat-resistance organic material is formed. CONSTITUTION:A surface of a sheet 11 is coated with the coating material in which active carbon is mixed in polyimide-group heat-resistance organic material, followed by printing to form a coating layer 12. Next, a solder paste 14 is printed in the position being in contact with a metal electrode 13 on the layer 12. Next, a semiconductor pellet 15 is placed between the sheets 11 on which the solder paste 14 is printed and the semiconductor pellet 15 held between the sheets 11 is reflowed. By this reflow, the paste 14 printed on the layer 12 moves onto the electrode 13 of the pellet 15 and soldering to a surface of the electrode 13 can be done. By this method, dispersion of the flux is prevented and reduced at the reflow, and catalytic reduction of the solder fusing plane becomes possible and consequently, the surface of the paste 12 is levelled thereby increasing the binding strength.

Title: Radiant tube and its manufacture
Inventor: OBARA NOBUHIRO
IPC: C04B41/87
Filed: 1988-04-19
Abstract: PURPOSE:To provide a radiant tube which has an anti-oxidation characteristic and is excellent in the resistance to thermal shock with a high strength at temperature over 1500 deg.C retained by using a material of carbon part or all of which is converted to silicon carbide. CONSTITUTION:Silicon monoxide gas is made to permeate and diffuse through a formed radiant tube consisting of a carbon material so as to let the formed radiant tube itself react with silicon monoxide gas to create a completely continuous structure. Since bores formed by the thermal decomposition gases of the binders such as coal tar pitch which is made during the sintering of the material are retained as they are after the material is converted to silicon carbide, the anti-thermal shock property of the material is very high. Since the silicon carbide section formed by conversion has no agents to aid sintering it has no sudden deterioration in the mechanical strength which is caused by the development of liquid phase of the agents to aid sintering at temperatures over 1500 deg.C. Its mechanical strength rather increases with higher temperatures up to about 2000 deg.C.

Title: Synchronizing type integral number multiple-speed device
Inventor: KATOU KATSUTOSHI
IPC: H03K3/78
Filed: 1982-06-08
Abstract: PURPOSE:To obtain an optional integral number of multiple-speed pulse having a constant pulse width at all times, by inputting a pulse signal having a constant duty factor obtained from a clock generator to a counter cleared with an original signal pulse of an indefinite period and comparing an output of the counter with a loaded optional integral number at a comparator. CONSTITUTION:The counter 47 is cleared by using the leading and trailing of a detected pulse signal 51 having a pulse width corresponding to a rotating speed. A comparator 48 compares a value of data loaded from an input data load interface 49 with that of the counter 47, an output 56 goes to a high level until these values are equal and goes to a low level when they are equal. An AND gate 46 is opened at first, and a pulse signal of a prescribed period outputted from a clock generator 45 passes through the AND gate 46 and is inputted to the counter 47. The counter 47 counts the number of inputted clock pulses and outputs a low level signal 56 when the result of comparison with the loaded data is coincident. Thus, the AND gate 46 is closed, the clock pulse does not pass through the AND gate afterward and an output signal 55 shown in the waveform is obtained from an output terminal 50. Even if an inputted signal 51 is a signal having a different duty ratio, i.e., a signal having a different period, an optional integral number of multiple-speed pulse having a constant duty ratio is obtained.
