Abstract: PURPOSE:To perform highly accurate measurement at a high speed, by subtracting the value, which is obtained by multiplying the relative moving speed of an object to be measured and a photoelectric sensor by the detection delay time of the edge signal of the object to be measured, from a detection displacement amount to eliminate the time delay of the output of the sensor. CONSTITUTION:The projection image 4A of an object 4 to be measured on a mount stand 3 is detected by light receiving elements 12A, 12B and convered by photoelectric converters 32A, 32B to calculate S-shaped signals (a), (b) equal in amplitude and shifted in a phase. The signals (a), (b) are processed by the differential operator 24, filter 30, detection means 28 and region comparator 26 in an edge detection circuit 14 to output a signal (g). The displacement of the object 4 to be measured is detected by a detector 46 to be inputted to a counter 48. The counter 48 sends a displacement amount to a correction circuit 22 every when the signal (g) is inputted. The displacement amount from the counter 48 is corrected by the speed signal detected from the output of an encoder 46 by a speed detection means 18 and the output of a time setting device 20 and stored in a memory apparatus 50 to be displayed. By this method, the time delay of the output of a sensor is corrected to perform highly accurate measurement at a high speed.

Abstract: PURPOSE:To reduce the volume of floatation in a discharge circuit as well as to make a minute diameter drillable, by insulating a tool electrode from a support device and a feed lever in order to reduce metallic parts existing in the discharge circuit of an electric discharge machining device. CONSTITUTION:A tool electrode 1 is supported by a support device 11. Since a pulley at the unillustrated motor side is set up so as to be situated in a more upper part than a pulley 12 at the tool electrode 1 side, the tool electrode 1 further receives upward tension while being pressed to the support device 11 by tensile force in a belt 13 whereby it rotates as making contact with a feed lever 14. This lever 14 serves as a fulcrum of leverage holding a supporting point in between, and an up-and-down motion in a feed screw 16 is transmitted to the tool electrode 1, therefore the feed lever is fed into the side of a work 2 as rotated. A contact part between the feed lever 14 and the electrode 1 is insulated by an insulating place 17. The work 2 is clamped and held on a work mount 3, and further clamped to a work tank 20 via a spacer 19. A machining path consists of a DC power source 5, a condenser 8 and a resistor R, while the electrode 1 comes in contact with the power source 5 through a brush 18.

Abstract: PROBLEM TO BE SOLVED: To smoothly ascend-descend stairs, and form a lightweight and compact structure by connecting a left slide rail and a right slide rail to each other by a rail connecting plate, sandwiching slide pieces between the left and right rails, and endlessly revolving these. SOLUTION: An ascending-descending device A is molded in a condition where a connecting plate 3 is connected to a left slide rail 1. A right slide rail 2 is fixed by screws in two places of a pressing-down hole 6 to the left slide slide rail 1. Slide pieces 4 are juxtaposed on the left slide rail 1 until they make a round without connecting individuals to each other. They are connected by screws in two places of the pressing-down hole 6 so as to be sandwiched by the right slide rail 2. They are installed on a bag and a carry or the like by using four places of installing parts 5 existing on the left and right of the ascending-descending device A. Here, the ascending descending device A is used by juxtaposing and installing by two sets.  Therefore, since the left and right slide rails 1 and 2 and the slide pieces 4 are made of synthetic resin having a small frictional coefficient, an object can be moved with small force.

Title: Method for brazing
Inventor: OKAZAKI KAZUHIDE
IPC: B23K1/20
Filed: 1989-09-18
Abstract: PURPOSE:To enable brazing of a low-melting ceramic substance without being limited with components of the ceramic substance by forming a metal thin film on the surface of the ceramic substance and simultaneously irradiating the formed thin film with ions. CONSTITUTION:A metal thin film, e.g. aluminum thin film, is formed on the surface of a ceramic substance by vacuum deposition, electron beam deposition, sputtering, plating, etc. The formed thin film is irradiated with ions simultaneously with or after the formation of the metal thin film to drive metallic molecules into the ceramic substance. The resultant thin film is then brazed with other ceramic substances or metals having a metal thin film formed on the surface thereof. If two or more layers of the metal thin films are formed on the surface of the ceramic substance, the ceramic substance and the metal thin film are heat-treated in parallel with formation of the first metal thin film cemented to the ceramic substance. Stress is removed and the metal thin film in the next layer is then superposed and formed.

Title: Method and device for controlling process
Inventor: SUZUKI KATSUYUKI
IPC: G05B13/04
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of a calculation load in optimizing calculation and to continue model prediction control by monitoring the calculation load by means of the optimizing processing of an evaluating function and mitigating a restricting condition in accordance with the calculation load. SOLUTION: A restricting condition setting means 14 sets the searching range of a manipulated variable updating value in model prediction control. A manipulated variable optimizing means 15 receives an inequality concerning the evaluating function and the restricting condition and decides the optimum manipulated variable by control period through the use of a numeral optimizing algorithm. The means 15 monitors the calculation load concerning solution searching in the numeral optimizing algorithm. When the calculation load becomes a certain prescribed value, a trigger S156 is outputted. Besides, the means 15 judges whether an optimum solution exists or not. When a restricting condition mitigating means 16 receives the trigger S156, it executes a mitigating processing with respect to restricting condition mitigating data.  The mitigating processing corresponds to the extension of the searching range of the optimum solution in the manipulated variable updating value.
