Title: Excessive crushing prevention device for crusher
Inventor: KAWADA YOSHI
IPC: B02C17/02
Filed: 1978-01-25
Abstract: PURPOSE: To perform a quick taking out of materials inside a crusher and obtain an easy control of the material level of the crusher by setting to a mill shell air holes and a casing surrounding the shell and having a secondary air source connected to it.  
     CONSTITUTION: The primary air and materials are supplied into a rough crushing chamber 5 through a supply port 2 to be roughly crushed. Next, the materials are finely crushed in a fine crushing chamber 6. The secondary air coming from a secondary air source 9 flows into the fine crushing chamber 6 through air holes 7 from a casing 8, preventing the staying of fine particles crushed in the fine crushing chamber 6, and quickly moving the fine particles toward a discharge port 3. The air holes 7, for example, above the mill shell 1 are to be closed and those under the mill shell 1 are to be opened by a seal metal 14, thereby the secondary air coming always from air holes 7 underneath to effectively apply on fine particles.

Title: Crystal growth method of gallium nitride compound semiconductor and manufacture of semiconductor laser
Inventor: NIDOU MASAAKI
IPC: H01S5/00
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To improve the flatness and the orientational property of crystallization, and to decrease the defect of lamination by a method wherein the surface of a crystal substrate is formed in such a manner that the tilt angle of the plane direction, which is equivalent to specific plane direction, is set within a prescribed value. SOLUTION: A GaN buffer layer 2 is crystal-grown on a sapphire substrate 1 having (1, -1, 0, 1) faces as the surface, and a GaN layer 3 is crystal-grown thereon. The crystal growth speed in the direction vertical to the (1,-1, 0, 1) faces is slow, and the atomic migration on the above-mentioned plane is intensified. As a result, a hexagonal gallium nitride compound semiconductor, which is smooth on the surface in the direction in parallel with the substrate surface and having uniform C-axial orientational direction, is formed. The same effect can be obtained even when the orientation of substrate is inclined by 5 degrees or less from the (1, -1, 0, 1) face orientation.

Abstract: PURPOSE:To prevent a wire from coming into contact with a neighboring wire or a stitch by providing a step for a specified stitch at the time of usual resin sealing after bonding. CONSTITUTION:Island 2, a stitch which constitutes the bonding part of external lead 3, and those parts of lead 3, which is to be provided with a step, that are to be pressed by the lead frame of metal mold 5 at the time of resin sealing are partially plated. At this time, partial plating is made over a long extent for the upper surface of lead 3 and over a short extent for the lower surface. When lead frame 1 is pressed by the metal old at the time of resin sealing, the pressed parts of plated lead are deformed upward due to the difference in the plated extent between the upper and  the lower surface. Immediately after this, molding is operated by resin sealing. Further, the degree of the step can be adjusted by varying the thickness of plating.

Abstract: PURPOSE: To obtain a thermo-sensitive and photosensitive switching element which the switching temperature is lowered under a good-characteristic state, by adding an auxiliary gate having a leak-property junction to a main thyristor.  
     CONSTITUTION: In the pnpn four-layer-structure semiconductor device consisting of anode 1, n base 2, p base 3 and cathode 4, auxiliary gate 8 which is the same conductive type as p base 3 is so added that it may be joined to n base 2 and be separated from p base 3. Then, pn junction J 4  between auxiliary gate 8 and n base 2 is biased reversely, and the lead current is flowed to pn junction J 1  between anode 1 and n base 2 in the forward direction. Now, when deep level or resistance layer 9 is formed in the pn junction J 4  part, much leak current is generated to shift the temperature dependence of the breakover voltage to the low temperature side. As a result, the off current is small, and the change rate of the breakover voltage to peripheral temperatures is large, and the switching temperature is lowered under the state where the off voltage rise rate is good.
