Title: Control method for wall thickness of spinning machine
Inventor: SUGIMORI YOSHIAKI
IPC: B21D22/18
Filed: 1989-03-07
Abstract: PURPOSE:To obtain a high wall thickness working accuracy by moving a roll in the mandrel rotational direction, detecting a gap of the roll and the mandrel in plural positions in the peripheral direction of the mandrel and at plural parts in the rotation axis direction, and superposing its function value as an error signal on a template signal. CONSTITUTION:Based on a command signal of a template 9, a position of a roller 5 is moved and adjusted against the peripheral surface of a mandrel 1. Prior to loading a working stock to the mandrel, the roller is moved in the mandrel rotation axis direction, while rotating the mandrel. In the peripheral direction of the mandrel and in the rotation axis direction positions of two parts or more, a gap of the roller and the mandrel, and the peripheral direction position of a detection point are detected. From this detection value, the maximum value or the minimum value of the gap, and their peripheral direction positions are derived, a function being equivalent to these calculated values is determined, and a signal corresponding to the function is superposed as an error signal on said template signal. In such a way, even if eccentricity and an inclination exist in the mandrel, an interval of the roll and the mandrel is always maintained in a template instruction value and the quality of a product can be improved.

Title: Method for removing foreign material
IPC: A22C17/08
Filed: 1992-03-16
Abstract: PURPOSE:To obtain a method for removing foreign materials without deteriorating the meat quality in which the foreign materials bitten not only in the meat surface but also in notches, etc., can be removed. CONSTITUTION:Meat is designed to be immersed in treating water, opened and loosened with the treating water. At least one of horizontal and vertical roll brush pairs 18 and 19 is rotated and the brushes of the roll brush pairs 18 and 19 are brought into contact with the surface of the meat with the rotation. Foreign materials sticking to the meat are peeled. That is, the foreign materials sticking to the surface of the meat are driven out with the brushes of the roll brush pair 18 and 19 and peeled. In this case, since the meat is brought into contact with the brushes in the water, the foreign materials can readily be peeled from the surface of the meat.

Title: Calculation of bond distance
Inventor: OKADA KENJI
IPC: G01N23/20
Filed: 1991-02-27
Abstract: PURPOSE:To rapidly calculate a bond distance by reducing calculation quantity by calculating the bond distance only when the absolute value of the difference between interatomic positions in an asymmetric unit is a fraction value or less. CONSTITUTION:In such a case that an equivalent position is one, for example, when the absolute value of the difference between Xa, Xb in an atom An (coordinates Xa, Ya, Za) 41 (n; integer) and an atom Bo (Xb, Yb, Zb) 42 is larger than the fraction value DX (max.) wherein a lattice constant is divided by the max. value of a bond distance 43 having to calculate a lattice constant, Xa and Xb are compared and, at the time of Xa<Xb, the position of Xa is moved to an adjacent unit lattice. It is again judged whether the absolute value of the difference between the position Xa+1 of an atom A1 and the position Xb of an atom Bo at this time is DX(max.) or less and, when the absolute value is DX or less, it is set as the candidate of the calculation of the bond distance 43 and, when the absolute value is DX or more, the bond distance 43 is not calculated. By this method, since wasteful calculation is omitted, the bond distance can be rapidly calculated.

Abstract: PURPOSE:To improve reliability, by adding copper (II) oxide as the raw material for electrode material, and specifying the conditions for the manufacturing process. CONSTITUTION:A raw sheet wherein at least organic binder and plasticizer are added into a ceramic dielectric material 1 whose main component is a lead compound is manufactured. An electrode pattern is printed on the raw sheet with a paste composition whose main component is copper (II) oxide. The desired number of said sheets and other sheets wherein electrode patterns are formed are laminated, and a multilayered structure is implemented. Said multilayered body is heat-treated in the air, and the organic binder in the inside is decomposed and scattered. Thereafter, the body undergoes reduction in a hydrogen atmosphere at a temperature of 175-250 deg.C. Then, the copper (II) oxide is reduced, but the lead compound in the dielectric material 1 is not reduced. Then, the body is sintered in a nitrogen atmosphere under the state wherein the body is embedded in the powder of carbon or graphite. Then, the surrounding of the laminated body becomes a slightly reduced atmosphere. The remaining oxide in the electrode 2 is reduced, and metal copper is obtained. Since the lead compound is used as the dielectric material and the copper is used as the electrode 2, a product that deteriorates the characteristics is not formed, and the reliability can be improved.
