Title: Numerical controller
Inventor: NAGATOSHI HIDEAKI
IPC: G05B19/4103
Filed: 1993-12-16
Abstract: PURPOSE:To suppress an error quantity small since the track of an arc after interpolation has an error about the track of a real arc as a segment becomes large in size when the arc interpolation using segment arithmetic by a DDA system is performed. CONSTITUTION:This numerical controller is provided with a segment corrector 1 which judges and corrects the size of the segment to a value less than a limit value and then outputs it, and further updates an input-side segment value with the outputted value and outputs a 0 command when the input value is 0, and a repeater 2 which commands the segment corrector 1 to repeat the process until the 0 signal of the segment corrector 1 is received. Then the device is provided with an arc interpolator 3 which inputs the segment outputted from the segment corrector 1 and coordinate values of two axes constituting the plane of the arc, performs arc interpolation, and outputs new coordinate values, and a coordinate managing unit 4 which manages the coordinate values of the arc outputted from the arc interpolator 3 and outputs them as new input coordinate values of the arc interpolator 3.

Title: Apparatus and method for supplying printing paste
Inventor: TAKAHASHI MASARU
IPC: H05K3/12
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent sagging and drop of printing paste having low viscosity from a nozzle due to own weight and to suppress viscosity change. SOLUTION: After discharge is completed, printing paste 18 is drawn into a tank 17 while reversing a spiral screw shaft 20 near a nozzle 19. And, after the paste 18 sagging from an end of the nozzle 19 is cut down on a screen by a cutter 34, a plug 30 is inserted into a discharge hole 31 at the end of the nozzle 19, thereby effectively preventing sagging and drop of the paste 18 due to its own weight and suppressing viscosity change. If the paste does not arrive at a viscosity set value D, a control means 38 controls to notify it to an operator by warning display of a warning means 42, a display means 40 to prevent erroneous supply and to eliminate the supply. Hence, the paste 18 arriving at the value D is always supplied.

Abstract: PURPOSE:To improve the ease of writing operation by a user, environmental conditions, safety and writing/erasing properties by providing a front pen tray at the bottom of the front side of a main blackboard system, and further a rear pen tray at the bottom of a rear board. CONSTITUTION:When using a rear pen tray 3b, a finger is thrusted into a handle 3b-2 to draw the handle out in an arrow B direction. Then the handle moves in an arrow B direction due to a guide rail 14, and the tip of the movable side guide rail 14b of the guide rail 14 comes in contact with a stopper 13 where the former is held by attractive force of a magnet. When storing the rear pen tray 3b, it is thrusted in and fixed to a predetermined position by holding force of both plate 5 and stopper 13. Further, a blackboard eraser and a pen deposited on the rear pen tray 3b are likewise stored. Consequently, damaging data due to its being caught by a protrusion on the rear pen tray 3b does not occur nor is present the potentiality of hurting the user when adhering a vertically long exhibit on the blackboard.

IPC: H01L21/3065
Filed: 1987-12-17
Abstract: PURPOSE:To enable a basement gate oxide insulating film to be prepared minutely and etched at a high speed by using an ion etching device that applied a parallel magnetic field parallel to the surface in the vicinity of a substrate to be etched and using a mixed gas of CCl4 and SF6 as a reaction gas, and by etching at a specified gas pressure and high-frequency voltage. CONSTITUTION:A substrate 5 is mounted on an electrode 2 in the lower part in an etching container 9, and the container is made vacuum. Next, CCl4 gas and SF6 gas with a 1-20% quantity to a CCl4 are controlled by a control valve 8, and introduced to the container 9. A pressure inside the container 9 is adjusted to about to 0.1-3.0Pa, and then a high-frequency voltage of 15.56MHz, adjusted to a peak voltage of about 50V, is applied to the electrode. At this time, plasma is generated by a high-frequency discharge inside the container. Since a magnetic field 6 is applied in the vicinity of the surface of the substrate 5, high-density plasma is produced on the surface of the substrate 5, and the density of chlorine ions is considerably increased. Therefore, polycrystalline silicon is etched by chlorine ions of low energy produced highly efficiently. Hence, low-damage etching that is excellent in anisotropy can be achieved.

Title: Non-destractive inspection method for fiber reinforced piston
Inventor: KAJIKAWA YOSHIAKI
IPC: G01N29/04
Filed: 1987-12-15
Abstract: PURPOSE:To improve the accuracy for an inspection by detecting an acoustic emission in a temperature variation process of a fiber reinforced piston by using a waveguide plate. CONSTITUTION:To one end of a plate-like stainless steel waveguide plate 20, an acoustic emission (AE) sensor 22 is attached, and on the other end, a fiber reinforced piston 10 taken out of a casting metallic mold is placed. In such a way, an AE generated from the piston 10 is transmitted through the waveguide plate 20 and can be detected by the AE sensor 22, but heat does not reach the vicinity of the AE sensor 22, and the AE sensor 22 can be used without being subjected to a thermal load. A transfer loss of the AE extending from the piston 10 to the waveguide plate 20 and a transfer loss by the waveguide plate 20 are only a little, therefore, the AE generated from the piston 10 can be detected with high accuracy.

Filed: 1990-11-26
Abstract: PURPOSE:To make an electrode electrostatically attract a sample with high reproducibility by flowing a cooling gas over the rear of the sample after microwave discharge is generated to impress an electrostatic attracting voltage. CONSTITUTION:Microwaves oscillated by a magnetron 3 are introduced into a treatment chamber 7 through a waveguide tube 4. A magnetic field is generated by a solenoid coil 5 mounted outside treatment chamber 7, and the etching gas is turned plasmatic by their action to subject a wafer 1 mounted on an electrode 2 to etching treatment.
