Title: Formation of lead/tin solder layer
Inventor: ANDO SHINJI
IPC: H01L21/60
Filed: 1988-04-27
Abstract: PURPOSE:To simplify the manufacturing process of a solder layer and improve the strength of die bonding, by using a plating liquid whose main components are hydroborofluoric acid, lead borofluoride, and tin borofluoride in an electric plating technique and by making its liquid have a specific plating current density. CONSTITUTION:Lead/tin solder is formed partially only on the metallic electrode of an n-type GaAs substrate. Then, electro-plating is performed with a plating liquid which has hydroborofluoride acid [HBF4], lead borofluoride [Pb(BF4)2], tin borofluoride [Sn(BF4)2] as its main ingredients and its liquid has a plating current density: 2.6+ or -0.8mA/cm<2>. In this way, a lead/tin plating layer is formed selectively only on the metallic electrode even with respect to the GaAs substrate where no patterning by photolithography is performed. Thus, this approach makes it possible to obtain a soldered layer which is easily manufactured and is superior in die bonding strength.

Title: Optical recording and reproducing device
Inventor: WATABE AKINORI
IPC: G11B7/125
Filed: 1990-04-25
Abstract: PURPOSE:To realize an optical recording and reproducing device with longer service life of a laser light source by decreasing an output of the laser or stopping superimposition of a high frequency signal onto a laser drive current for the standby period. CONSTITUTION:A standby period (e) is referred to as a period when no recording nor reproduction is implemented and a period when a laser beam is subject to positioning or access to a disk or a track. The laser power for the period is set lower than that for a signal reproducing period in the case of focusing control of a laser beam to a disk. That is, an output of a high frequency current drive circuit 13 is attenuated by an amplitude control circuit 14 for the standby period (e) and a semiconductor layer 8 is stimulated through a switch 11 to reduce the laser output more than that for the reproduction period. Since the wear of the laser is prevented for the standby period, the available service period of the optical recording and reproducing device is extended due to the longer service life of the laser.

Title: Manufacture of nonoriented silicon steel plate with superior magnetic characteristic
Inventor: MIYOSHI KUNISUKE
IPC: C22C38/00
Filed: 1980-08-08
Abstract: PURPOSE:To obtain a high grade silicon steel plate with a low iron loss value such as >=S8 by adopting short time stepped soaking in a specified temp. range as the condition of the final recrystallization annealing of a steel strip worked from a slab for a nonoriented silicon steel plate. CONSTITUTION:A slab for a nonoriented silicon steel plate contg. <=0.010% C, <=4.0% Si and <=1.0% Al is worked into a steel strip having the thickness of the product. This strip is quickly annealed in a nonoxidizing atomosphere at 850-1,000 deg.C for about 30sec-4min in the former step and at 1,000-1,100 deg.C for <=1min in the latter step. When the temp. in the former step is below the lower limit, predetermined recrystallization is not attained to deteriorate the iron loss, and when the temp. exceeds the upper limit, impure products such as nitride and oxide are easily formed to deteriorate the magnetism. On the other hand, the temp. in the latter step is below the lower limit, the recrystallized grains are smaller to make enhancement in magnetism difficult, and when the temp. exceeds the uppe limit, impure products are formed on the surface of the steel plate. Shorter holding time for soaking in the former step makes the recrystallized grains smaller. Longer holding time for soaking in the former step and that in the latter step result in a slight effect and no effect, respectively.
