Abstract: PURPOSE: To form circuit configuration which is executable for CMOS technique, so as to recover comparatively small signals by composing a circuit of a signal amplitude detector provided with a differential precise gain amplifier, a maximum peak detector, a minimum peak detector and a capacitor switching type amplifier. CONSTITUTION: A signal amplitude detection subsystem 30 inspects an in-signal, and when the inter-peak amplitude of the signal is included within a prescribed range, a control signal Vout is generated to be used for gating the in-signal VIN. For this purpose, a differential precise gain amplifier 40 establishes a DC reference voltage VACG, adjusts a common mode signal component from VIN, and amplifies this small signal only for the exact quantity. This reference voltage is measured by a maximum peak detector 42 and a minimum peak detector 44, while swinging the maximum peak and minimum peak of VIN around it. The peak detector 42 captures the positive peak of VIN and outputs a signal X, and the negative peak of VIN is captured by the peak detector 44 and is outputted as Y. A capacitor-switching type amplifier 46 outputs the control signal Vout , while algebraically combining X and Y.

Abstract: PURPOSE:To produce snow without use of an air compressor by a method wherein a nozzle ring is attached on an air outlet of a tubular snow producing machine main body in which a blower is installed, and the nozzle ring is provided with high-pressure water jet nozzles and water-snow production accelerator mixture jet nozzles. CONSTITUTION:When a blower 2 and pumps 7 and 10 of a snow producing machine main body 1 are operated, water drops 12 are blown from many high- pressure water jet nozzles 5 in the oblique forward direction and in the inward direction of the radius of a nozzle ring 4, and mixture liquid is blown from two or more mixture jet nozzles 6 in the oblique forward direction, that is, into cold air. Snow production accelerator contained in the mixture liquid serves as catalyst of ice crystal core formation and ice cores 13 are formed at higher temperatures than in former method. The water drops 12 are super-cooled down by cold air jet stream A, strike against the ice cores 13 and turn into water drops containing ice cores. The water drops containing ice cores exchange the latent heat with ambient air until they turns into ice-water mixture, thus snow-like crystals are produced and carried by the air jet stream A.

Title: Immersion nozzle for continuous casting and method of collecting suspended inclusion in mold
Inventor: TSUDA MASAHITO
IPC: B22D43/00
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce the cast metal surface flaw attributable to the inclusion and the surface grinding before rolling, thereby improving the yield and quality, and preventing easy separation of the inclusion which is stuck once and grown by providing the bottom surface of the immersion nozzle with concave grooves. SOLUTION: The downward flow hits the side wall of continuous casting mold, charges its flow direction, and rises toward an immersion nozzle 7, and at that time, the inclusion is floated, but the upward flow is weakened near a bottom surface 7Aa of the immersion nozzle 7, and the floating inclusion sticks to the bottom surface 7Aa of the immersed nozzle 7 and grows. Since concave grooves 11 are formed in the bottom surface 7Aa of the immersion nozzle 7, the floating or moving inclusion sticks to the inner surface of the grooves 11, and the sticking inclusion is not so easily separated. It is preferable because the multiple grooves 11 are provided in the direction orthogonal to the discharge direction A of the molten steel discharge port, thereby decreasing the separating action.

Title: Copying paper conveying device
Inventor: GOSHIMA YOSHITOMO
IPC: G03G15/00
Filed: 1979-05-30
Abstract: PURPOSE: To perform sure copying material feeding by providing the means of detecting whether transfer material is surely gripped in a gripper or not in the copying material feeder which grips the copying material in the gripper and conveys the same.  
     CONSTITUTION: Transfer material P (P') supplied by feed rollers 10 abuts against a static timing roller 51 and forms a deflection L 1  and this causes a microswitch 103 to actuate. (Fig. A) A timing roller 51 actuates to start fast feeding so that the transfer material P (P') abuts against a gripper 53. (Fig. B) At this time, the deflection L 1  is kept formed and the microswitch 103 keeps actuating. When the copying material P (P') is surely gripped by the gripper 53, the deflection becomes L 2  and this causes the microswitch 103 to stop and the timing roller 51 to stop, thus ordinary feeding is resumed. (Fig. C) If the feed amount of the copying material P (P') is insufficient owing to the slip or the like of the copying material P (P') and the microswitch does not actuate as the deflection does not become L 1  in the Fig. A, the copying operation is stopped.
