Filed: 1981-12-08
Abstract: PURPOSE:To braze and join high m.p. metals to each other economically and efficiently by heating electrically the high m.p. metals which are superposed by sandwiching a brazing filler metal consisting of Mo and Ru. CONSTITUTION:The joining end parts of the 1st high m.p. metal 6 and the 2nd high m.p. metal are superposed by sandwiching a brazing filler metal 8 consisting of Mo and Ru. While the outer sides of the superposed parts are held  grasped under pressure with electrodes 9, 9' of a spot welding machine, electricity is conducted to the electrodes to join both metals 6, 7. A green compact of mixed powder of Mo and Ru or the sintered body thereof is used for the above- described metal 8. With the alloy of Mo and Ru, there is an eutectic point of about 1,950 deg.C eutectic temp. at the point where the content of Ru is about 42wt%, and therefore the brazing filler metal of the compsn. around the same is suited as a brazing filler metal for the high m.p. metals. Further, this brazing filler metal has good wettability with the high m.p. metallic materials such as W, Mo and the like.

IPC: F23N1/02
Filed: 1985-09-09
Abstract: PURPOSE:To prevent loss of balance in between the combustion gas and fuel by using a fuel supply device which changes the fuel discharge amount according to the pulse state and at the same time providing a pulse delaying section at a control section which controls the combustion air and fuel, which delaying section gradually changes pulses to a fuel supply device. CONSTITUTION:When signals inputted to the terminals AN1, AN2, and AN3 of a microcomputer 12 are compared at a comparison section 27, and it issues signals of 'strong' or 'weak' or 'off', the burner motor control section 30 changes over burner motor 3. At the same time the signal from the comparison section 27 is sent to a pulse delaying and changing section 31, and this changing section drives a drive circuit 4' through a photo-coupler 20 to actuate a pump 4. This changing section 31 compares the signals from a pulse generating section 32 and a target pulse setting section 33 at a comparison and detection section 34, and the cycle that difference in the comparison is corrected little by little at a correction section 35 to feed a corrected difference back to the pulse generating section 32 is repeated in order to make the pulse approach a target pulse gradually. With this arrangement it is possible to limit the air and fuel ratio to minimum when the combustion amount is changed over.

Title: Manufacture of solar cell
Inventor: SASAKI HAJIME
IPC: H01L21/70
Filed: 1990-07-27
Abstract: PURPOSE:To make it possible to manufacture a solar cell board at low cost and with ease by using a heat resisting mold whose surface is coated with boron nitride about the manufacturing method of a solar cell which charges silicon powder into the heat resisting mold, heat-melting the silicon powder, and manufactures the solar cell board. CONSTITUTION:A proper amount of Si powder is set into a recessed part of a mold 1 where a cover 2 is placed on the mold. The recessed part of the mold 1 is cut at a depth from 0.2 to 1mm. The depth of cut is capable of controlling the thickness of a Si board to be formed. Then, the surface between the mold 1 and the cover 2 is coated with boron nitride. The mold into which Si powder is charged, is set to a furnace where the whole mold is heated at a temperature which exceeds the melting point of silicon. After the Si is melted, the temperature is lowered so that the Si may be solidified. When BN is used as a parting agent, the BN applied for the coating is not fused to the Si. Therefore, it is unnecessary to coat every time so that the mold may be used repeatedly. The molten Si does not react with the mold, which makes it possible to part the Si from the mold easily.
