Title: Dull roll for cold rolling
Inventor: YAMADA YASUHIRO
IPC: B21B27/00
Filed: 1986-06-30
Abstract: PURPOSE:To improve the wear resistance of a dull roll by comprising the micro configuration of a rough surface of recesses, embossed parts, and flat parts and specifying the area ratio of the flat parts. CONSTITUTION:Embossed parts 2 having a nearly uniform height around recesses 1 on the surface of a roll 3 are pressed onto the surface of a steel stock 7 by a strong pressure. By that pressing, local plastic material flows are generated in the vicinity of the surface of the stock 7 whose material is softer than that of the roll 3, so that the metal of the stock 7 flows into the recesses 1 of the roll 3 to form a rough surface. In that time, the top surfaces of the steel sheet metal embossed inside the recesses 1 become flat faces 8 being unchanged as the initial steel sheet surface. Surface parts 9 of the stock 7 pressed against flat parts 6 outside the embossed parts 2 between adjacent recesses 1 do not change and become flat faces 9. Then, the height of the flat faces 8 is higher than or equal to that of the flat faces 9. The flat parts 6 (nonmachined) are very effective for the wear resistance of a dull roll, so that the area ratio of the parts 6 is made to be 0.2 or more.

Title: Manufacture of semiconductor laser
Inventor: MAEDA KATSUNOBU
IPC: H01L21/302
Filed: 1988-06-20
Abstract: PURPOSE:To prevent the deterioration of characteristics by removing an oxide film with chemical etching through heat treatment in H2 gas and getting rid of a natural oxide film and a modified layer through thermal etching in a high vacuum mainly comprising arsenic. CONSTITUTION:A clad layer 2, an active layer 3, a first clad layer 4, a high resistance restraining layer 5 and a block layer 6 are grown successively onto a conductive substrate 1. The block layer 6 is chemically etched to a striped shape. Since the high resistance restraining layer 5 is formed onto the top face of the first clad layer 4 at that time, the first clad layer 4 is not etched, and the high resistance restraining layer 5 is etched, thus extremely thinning an oxide film generated. The oxide film is taken off through heat treatment. A natural oxide film and a modified layer 9 are shaped onto the surface of the high resistance restraining layer 5 at that time. The natural oxide film and the modified layer 9 are removed through thermal etching, and the high resistance restraining layer 5 is etched. A second clad layer 7 and a contact layer 8 are grown successively, thus acquiring a semiconductor laser.

Filed: 1977-12-22
Abstract: PURPOSE: To lower a limit that prevents going-out by blowing, by mounting a by-path duct and an adjusting valve between an air discharge port and an outlet at the exhaust side of a heat exchanger.  
     CONSTITUTION: When an accelerator pedal 12 is rapidly opened due to quick deceleration, a signal for indicating the opening of a by-path valve 25 is put out because output N×G from a set instrument 13 reduces in stages, the by-path valve 25 is opened and by-path pipes 26a, 26b are communicated. Thus, excess air among compressed air discharged from a compressor 1 is discharged to an exhaust duct 28 through a by-path duct 26.

Abstract: PURPOSE: To provide required intensity even when a power source is a low voltage at the time of high-speed scanning by providing a luminescent element and a rectifier connected in series with the luminescent element on a luminescent element luminous circuit. CONSTITUTION: When a luminescent element luminous circuit is scanned and a current is injected by the applied voltage in the forward direction, the current is first used to charge a capacitor 109 in a luminescent element 1, and a luminous section main body 107 is not illuminated during this period. When the charging time elapses to attain the forward voltage, the luminous section main body 107 starts illuminating. When scanning is completed and a reverse voltage is applied, no current is injected to the luminescent element luminous circuit by the valve action of a rectifier 2, and a closed circuit is formed inside. The electric charges left in the capacitor 109 flow to the luminous section main body 107 through an internal resistance 108, and illumination is continued.  When the scanning speed is increased, the next scan starts before the electric charges left in the capacitor 109 completely flow to the luminous section main body 107 after one scan of the luminescent element 1 is completed, and the luminescent element 1 is continuously illuminated.

Title: Manufacture of semiconductor device and annealing device therefor
Inventor: KATO HISAYUKI
IPC: H01L21/20
Filed: 1988-06-24
Abstract: PURPOSE:To enable recovery of a wafer from damage favorably in yield rate by applying a plurality beams of light of different wave lengths to the surface of a wafer within the same treatment space at the same time or in order so as to perform annealing. CONSTITUTION:A plurality of light beams 5-7 that the wave length varies are applied to the surface of a wafer 1 at the same time or in order within the same treatment space 3 so as to perform annealing. Since the remaining faulty modes within the wafer 1 are various by the process such as film formation, heat treatment, etching or ion implantation, it is difficult to recover from the damage simply by applying the light of the single wave length. Accordingly, if the light beams 5-7 of the wave lengths in accordance with various kinds of faulty modes are applied to the wafer 1, sufficient effect of recovery from the damage can be obtained, and further if these light beams 5-7 are applied within the same treatment space, efficient annealing can be done in a short time. Hereby, the recovery from damage of the wafer 1 can be achieved at high yield rate.
