Title: Method of machining crankshaft pin
Inventor: KOBAYASHI CHUTARO
IPC: B23Q11/00
Filed: 1986-10-20
Abstract: PURPOSE:To make it possible to facilitate the disposal of chips with no torsional load being exerted to a crankshaft, by arranging cutters on both diametrically opposite sides of the crankshaft, by making these cutters face to the pin parts, respectively, and by rotating the cutters in directions reverse to each other. CONSTITUTION:A cutter 10 set on one side of a crankshaft W and a cutter 20 on the other side thereof are rotated in direction reverse to each other to machine parts 20 having a phase difference of 180 deg. therebetween, at both diametrically opposite sides of the crankshaft W, simultaneously. Accordingly, torsional loads produced in the crankshaft W in the rotating directions of the cutters 10, 20 during cutting are canceled out with each other, and therefore no useless torsional load is exerted to the crankshaft W. Further, since the cutters 10, 20 are arranged on both sides of the crankshaft W, chips produced during cutting scatter in one and the same direction even though the rotating directions of the cutters 10, 20 are reverse to each other. Accordingly, it is possible to facilitate the disposal of chips.

Inventor: TAKAHASHI SEIICHI
IPC: C23C14/14
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a technique capable of obtaining a copper wiring of high reliability at a low cost. SOLUTION: When copper material is filled into recessed parts 131 and 132 cut in a substrate 10 for the formation of a copper wiring, a copper CVD thin film 16 is formed thin on an insulating film 12 through a CVD method, then a copper sputtered thin film 18 is formed thick, and then a heat-treatment is performed. When the copper CVD thin film 16 is turned fluid, the copper- sputtered thin film 18 starts reflowing, thereby copper material is filled in the recessed parts 131 and 132 , and thus copper wirings 251 and 252 free from voids are formed. As a thick copper sputtered thin film 20 can be used, the copper wirings 251 and 252 can be lessened in cost.

Filed: 1988-10-03
Abstract: PURPOSE:To make it possible to perform the surface treatment of a thin insulation film with plasma by generating a lower pressure inside a case electrode by the rotation of a roller which forms another electrode and performing the surface treatment with the generated lower-pressure plasma. CONSTITUTION:A case electrode 13 opposing to a roller 2 which forms another electrode is formed in a square box open on the side of the roller, and a small gap is formed between the entire peripheries of the open front face and the periphery of the roller which forms another electrode 2. When an object 1 to be treated moves by the rotation of the roller 2 and the air inside the box is drawn from the inside to lower the pressure, a rare gas is fed from a gas reservoir 9 through a gas feed pipe 7 into the box to displace the air, and the pressure of the rare gas in the box is maintained at a desired lower level by the adjustment of a flow control valve 8. When the switch 12 on the outlet side of a power supply 5 is closed, a lower-pressure plasma 6 is generated in the rare gas in the box, and the filmy object 1 is surface-treated with this plasma.

Filed: 1987-10-02
Abstract: PURPOSE:To improve a throughput during the waiting of read access by inserting a waiting cycle only at the time of generating access to a destination register before the completion of the read access at the time of executing the read access to a peripheral device with slow response. CONSTITUTION:In case of executing read access to the peripheral device with slow response, an instruction executing unit 10 advances the executing of another processing without waiting correspondingly to the peripheral device. The execution and control of the read access are executed by an access control circuit 32, a bus control unit 34 and a register access control circuit 18, and only when the register is tried to be accessed before the completion of the read access, the unit 10 inserts a waiting cycle into the execution cycle. Thus, the drop of the throughput in the instruction executing unit 10 can be suppressed even in the waiting of the read access.

Title: Master disk for optical disk and stamper and their production
Inventor: IKEDA NORIHIRO
IPC: G03F7/40
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To improve signal detection accuracy and recording density by constituting lands of oxidized films, thereby making the surface roughness of the lands smaller and the taper angle of the lands larger. SOLUTION: A silicon substrate 10 is heated and the silicon oxidized film 11 is formed on this substrate 10. A photoresist 12 is uniformly applied thereon and the surface of the photoresist 12 is covered with a mask 13 having the prescribed shape corresponding to the tracks of a magneto-optical disk after drying and is exposed. This photoresist is developed to remove exposed parts 12a and reactive ion etching is executed. At this time, the taper angle α of the lands 15 is increased by anisotropic etching. The patterned resist 12 is removed to form a master disk 14. As a result, the land 15 surfaces of the oxidized film 11 have the flatness of an atom level. Since the oxidized film 11 is patterned by the reactive ion etching, the taper angle θ of the lands 15 increases.  Consequently, the accuracy of signal detection is improved and the transparent substrate of the magneto-optical disk having the high recording density is formed.

Title: Incinerator for removing harmful material
Inventor: MAEJIMA TAKASHI
IPC: F23L17/00
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To surely prevent scattering of harmful materials into the air by providing a removing part for removing harmful materials which are generated in an incinerator, being communicated with the incinerator, and producing an air stream which flows from the incinerator to the removing part by using a negative pressure means so as to constantly keep the inside of the incinerator in a negative pressure condition. SOLUTION: A primary combustion chamber 9 and a drying chamber 10 of an incinerator 2 are constantly maintained so as to have a negative pressure owing to an air circulation system wherein air which has been charged from air inlet ports 6a formed on an incinerator bed 6 is constantly transferred to a direction A by a fan 3 in a removing part 2a. When raw refuse 4 and materials 5 to be burnt are stuffed into the incinerator 2 for combustion, combustion is started from the lower layer portions as air is sucked, so that the upper layer portions turn to be an oxygen deficient condition, resulting in generating large quantity of unburned gases and unburned carbon in the incinerator 2 and thus making a reduced atmosphere.  Such unburned gases, unburned carbon and the like in the reduced atmosphere are combusted in a secondary combustion room 11 by means of a burner 12 so as to completely remove harmful materials, thereby exhausting flue gases from a flue gas port 13.
