Title: Manufacture of silicon carbide single crystal
Inventor: MATSUSHITA YASUHIKO
IPC: H01L21/365
Filed: 1987-01-20
Abstract: PURPOSE:To make it possible to suppress the occurrence of defects in laminated layers, by making the crystal growth face of a substrate be not in parallel with a plane (0001) and plane (0001'). CONSTITUTION:The crystal growth face of a substrate is made to be a face, which is neither in parallel with a plane (0001) nor a plane (0001'). For example, the plane (0001), which is the face of a 6H-SiC single-crystal substrate 3, is cut and polished in a slant direction. The face, which is not in parallel with the plane (0001) that is obtained by polishing and the like, is formed and made to be a crystal growth face. A 6H-SiC single-crystal is epitaxially grown on the substrate 3. When Si atoms and C atoms are bonded at a growth interface, strong actions are applied in two orthogonally intersection directions. Thus the arrangement pattern of the atoms in the growth layer 4 is hard to slip, and the occurrence of defects in laminated layers is suppressed.

Title: Chemically separating and recovering method for palladium
Inventor: ISE ATSUSHI
IPC: C22B11/00
Filed: 1979-02-01
Abstract: PURPOSE: To separate high purity Pd from an acidic soln. contg. dissolved Pd and other metals by adding a reducing buffer soln. to the acidic soln. to maintain a predetermined pH value, thereby preventing precipitation of other metals such as Al and Fe in precipitation of Pd.  
     CONSTITUTION: An acidic soln. contg. dissolved Pd and other metals such as Al and Fe after cleaning car exhaust gas, etc. is pH-adjusted with a reducing buffer soln. such as a sodium formate soln. whose pH does not induce precipitation of the metals other than pd. When the acidic soln. is of pH≤1.8, an alkali soln. such as a NaOH soln. is added to easily perform pH adjustment. Thus, the acidic soln. hardly reaches a pH value at which the metals other than Pd precipitate even if a slightly excess amt. of alkali is added, and little other metals are mixed into Pd precipitated. Accordingly, high purity Pd is separation-recovered chemically and efficiently.

Title: Electronic watch with alarm
Inventor: KUMADA KIYOSHI
IPC: G04G13/02
Filed: 1979-02-05
Abstract: PURPOSE: To provide an alarm easy to understand and to use at an electronic watch by independently providing the alarm set state and sound enable state and indicating both with different marks.  
     CONSTITUTION: When an electronic watch is set at single alarm control mode, the indication selection signal 11a of a mode controller 11 becomes H level to select the hour and minute in the content of an alarm counter 6 instead of the month and day of a counter 3 and to indicate them on a sub-indicator. Since the indication control signal 11b becomes repeated H and L levels in this mode, the AL indication on the alarm indicator 18 is flashed through an OR gate OR1 and an AND gate A1. When a ring function set circuit 13 is set to set the output signal 13a to H level in the normal mode, an AND gate A3 is closed. Thus, the coincidence signal 8a from a comparator 8 enables to be applied to a speaker drive circuit 9. When an alarm time comes, the circuit 9 is driven, and the speaker 10 thus generates an alarm sound. Then, an AND gate A4 is closed to energize a ring function mark indicator 19 ON.
