Title: Brazing material for titanium material
Inventor: KURAHASHI KAZUO
IPC: B23K35/40
Filed: 1985-05-25
Abstract: PURPOSE:To reduce the time for brazing and to improve brazing strength and workability by using a tape-shaped brazing material formed by combining many strands each having a sheath layer consisting of a layer having the m.p. lower than the m.p. of Ti on the outside of a Ti core material into a shell body consisting of a metal having the m.p. lower than the m.p. of Ti. CONSTITUTION:The brazing material B is made into the tape shape combined with the many strands each consisting of the Ti core material 11 enclosed with the sheath layer into the shell body 10 consisting of a Cu-Ni alloy. The Ti, Cu and Ni are quickly diffused into each other by the heating to be executed for brazing, thereby welding being executed. The quick brazing is thus made possible. Such brazing is made possible because the Ti diffusion of the Ti core materials 11 is made easy by the large contact area of the materials 11 with the sheath layer and therefore the reduction of the time for brazing and the operation are made easy. The components of the brazed part are made uniform and the brazing strength is improved.

IPC: H04N5/232
Filed: 1994-04-28
Abstract: PURPOSE:To improve the operability by storing data to other memory when number of write limit times of an EEPROM is exceeded. CONSTITUTION:An electric signal image by an image pickup section 210 is converted into a video signal by a signal processing section 211 and displayed on an external monitor from an output terminal 212. A signal from a remote control device is detected by an infrared ray sensor 209 and a CPU 201 reads a signal and recognizes a command via a PIO 208. A command from a personal computer received from a serial I/O connector 207 is converted into an electric signal by a data transceiver 206 and fed to an SIO 205. The CPU 201 decodes the command for its operation. A data write means writes data in a memory block. When number of times of write exceeds a prescribed number, since a write memory block is revised, the erasure of data to be stored is prevented even when power is interrupted. Thus, trouble of storing data for each start is omitted and the operability is improved and since the data are not stored in the same memory block in excess of the write limit number, the operability is improved.
