IPC: C23F4/00
Filed: 1992-01-29
Abstract: PURPOSE:To provide the method capable of widening a temp. range in which selectivity appears in a selective CVD method. CONSTITUTION:A thermally oxidized film of Si is etched to remove a part thereof, and a substrate 14 in which a via hole 13 has been opened is cleaned by a 2% hydrofluoric acid aq. soln. and is dried. This substrate 14 is heated by a heater 15 or an infrared ray lamp 16 so that its surface temp. will be regulated to 300 to 1000 deg.C. In this way, H is removed from the surface of Si as well as an OH group is removed from the surface of SiO2, and both surfaces are cleaned. The substrate 14 after the cleaning stage is subjected to CVD by using DMAH(dimethylaluminumhydride) as the stock of Al, by which the selective growth of Si/SiO2 is permitted in the wide temp. range of 150 to 300 deg.C. The temp. range of the selective appearance is 150 degrees, and it reaches 15 times the conventional width of 10 degrees. Thus, the temp. control of selective CVD is made easy, and the constitution of the apparatus is made simple.

Title: Rotating type cutting tool
Inventor: OCHIAI MASAHIKO
IPC: B26B19/16
Filed: 1993-02-03
Abstract: PURPOSE:To eliminate shaking and chattering of a cutting edge by enabling the securing of the depth of burying the cutting edge on a base even when a smaller diameter is required in a rotating type cutting tool in which a plurality of cutting edges are buried into a circumferential surface of the base molded in a cylinder. CONSTITUTION:A shaft part 3 or a center hole is formed integral in the center of both end faces alone of a base 1. This eliminates a rotating shaft passed through the base 1 as in the past and enables the burying of a side end of the root of the cutting edge 4 deeper near the center of the base 1. Thus, the depth of burying the cutting edge 4 into the base 1 can be secured even when a smaller diameter of a cutting tool is required thereby eliminating the shaking and chattering of the cutting edge.

IPC: H01J37/08
Filed: 1982-03-16
Abstract: PURPOSE:To obtain a stable ion beam by confining the ballistic scattering electron to be produced when the secondary electron accelerated from the ground cathode side will impinge against the draw-out electrode thereby eliminating the minute discharge. CONSTITUTION:An ion beam emitted from an emitter 2 will impinge against the surface A of a ground cathode 10' to emit the secondary electron (e), but since an projection electrode 21 is covering over the surface A the field due to the draw-out electrode 7' on said surface A will weaken thereby the secondary electron to be drawn out and accelerated to said electrode 7' will be reduced considerably when compared with total number of secondary electrons produced from said surface A. Furthermore the secondary electron to be accelerated to said electrode 7' will impinge against the surface B of said electrode 7' to produce the ballistic scattering electron, but since there is a projected section 20 at said electrode 7' side, it will repeat the back face scattering in said section 20 and scarcely pass through the gap D between said section 20 and the projected electrode 21.

Title: Simplified thread-setting sewing machine
Inventor: KASUGA NOBORU
IPC: D05B53/00
Filed: 1989-02-23
Abstract: PURPOSE:To simplify the thread setting work to provide ease of the work by a method wherein in needle thread setting work for sewing preparation, a line of needle thread is passed through a needle eye after it is pulled out from a needle thread supply source and set on a thread guard and the upper guide of the thread guide above a sewing machine frame, and a signal generating device is operated. CONSTITUTION:When a presser foot is lifted by operating a presser bar lifter in thread setting, a driven roller 16 is moved apart from a driving roller 10 so that a clearance is produced, allowing a line of needle thread 2 to be set in it. The needle thread 2 pulled out from a thread spool of a needle thread supply source is led between the clearance, and then to the upper guide of a needle thread guide 6 through over a thread guard 20 above a sewing machine frame. Next, the needle thread is passed through a clearance between a thread take-up lever 29 and the sewing machine frame from above the thread take-up lever 29, and then passed through an eye of a needle. Thus, thread setting work is completed by an operator. When a signal generating device is operated, a thread setting instruction is output. Control data is read out from a thread setting control data memory, and a needle thread supply stepping motor 9 is brought in operation. Further, the needle thread 2 is set on a thread take-up spring below between the thread guard 20 and the thread take-up lever 29 by movement of a transmission device 27.

IPC: C21B7/14
Filed: 1978-04-11
Abstract: PURPOSE: To control the outflow of slag by providing a vertical and/or horizontal tilt-action exhaust port on the both ends of molten slag distributor.  
     CONSTITUTION: The distribution trough 2 has the vertical tilt-action exhaust ports 3 and 3' which are concurrently operated on the bearings 11 and 11' by the operation of the cylinders 12 and 12' or on the bearing 8 by the operation of the worm jacks 7 and 7' according to need. Accordingly, when the outflow of blast furnace molten slag, for example, from the main trough 1 is changed, the outflow can be controlled by turning the exhaust ports 3 and 3' upwards when the outflow is small or by turning them downwards when the outflow is great. Also, when the both outflow of slag at the exhaust ports 3 and 3' is equalized or any one flow rate of the both exhaust ports is kept constant, the flow rate of molten slag can be controlled freely by operating the worm jacks 7 and 7'.
