Title: Lime flux for smelting metal
Inventor: TAJIMA RITSUO
IPC: C21C7/04
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To improve the slag-making property by increasing a molten metal stirring effect during a flux injection without adding fluorite, and to generate a versatile slag of excellent quality which contains no fluorine or non-slag lime in the molten condition, is suitable for a phosphatic and potassic fertilizer, and a raw material of cement and a road bed material. SOLUTION: Powder calcium hydroxide is added to lime flux containing powder quick lime. Alternatively, most of lime flux is changed into calcium hydroxide. These stuffs may be of lump shapes as necessary. The calcium hydroxide is fed into the molten metal in a metal smelting furnace, and the calcium hydroxide is decomposed into quick lime large in a specific surface area. Slight steam explosion generated during the decomposition is intentionally induced, the contact of the molten metal and the flux together with a carrier gas is promoted, and the hydroxide flux is reacted with sulfur and phosphoric acid in the molten metal to promote generation of the molten slag.

Title: Ultrasonic diagnosing apparatus
Inventor: IIDA ATSUO
IPC: G01N29/24
Filed: 1990-07-20
Abstract: PURPOSE:To permit different probes to have data on the amount of delay in common so as to restrain a rise in the cost of an ultrasonic diagnosing apparatus by specifying the ratio of the pitch of division of the arrays of a linear probe to that of the arrays of an annular probe in such a way that the former is some integral number (including 1) times the latter. CONSTITUTION:Annular array vibrator 3 consists of a set of several concentrically arranged vibrators and carries out focusing to predetermined depth by means of excitation or reception of ultrasonic waves with a certain delay for each vibrator element 5, 5..., and carries out dynamic focusing by sequentially varying the amount of delay in such a manner as changing a set focusing distance at several stages. The pitch PA of division of the annular vibrator 3 is the same as the pitch Pl of division of the linear array vibrator 1 or the pitch PL of division of the linear array vibrator 1 is some integral number times that of the annular array vibrator 3 whereby both of the vibrators 1, 3 have delay data in common. The delay data are thus made common to the annular probe and the linear probe, so as to restrain a rise in the cost of an ultrasonic diagnosing apparatus.

IPC: G02B6/44
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to decrease the skew between optical fibers by using fibers having the transmission time difference (skew) for nearly compensating the differences in the optical path lengths by the difference in the spiral radius of the optical fibers in the state that a tape-like coated optical fiber is not housed in an optical cable for at least one of the optical fibers.

Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a structure and a manufacturing method without deterioration in reliability and characteristics in an MOS-type field effect transistor, with respect to a semiconductor having a wiring formed in a dual-damascene method. SOLUTION: A first stopper nitride film 7 is removed from an upper region, functioning as an active region of a transistor above a gate electrode 4, so that moisture can diffuse upward.

Title: Method for detecting welding defect in resistance welded tube
Inventor: MOTOYOSHI TAKU
IPC: G06T7/00
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To accurately detect defects of a weld zone by sensing, through the image pickup by a television camera, the light quantity varying outside the weld zone by sparks generated at the time of welding. SOLUTION: With a television camera 12 arranged above the weld zone 7 of a resistance welded tube, an outer area is continuously imaged on both sides in the tube-making direction of a weld zone 7. With sparks generated in the weld zone 7, an halation is developed around the sparks in the image of the television camera 12. The light quantity is low in normal welding in the outer area on both sides in the tube-making direction of the weld zone 7; once the sparks are generated, the light quantity grows high and varies greatly, which can be accurately detected. Receiving the signal of the television camera 12, an image processor 14 calculates the average light quantity on the outer area on both sides in the tube-making direction, while an calculator 15 discriminates the defective degree of the weld zone 7.  The generation of sparks can be detected without being influenced by a light quantity from the ignition state of the weld zone 7 in normal welding; therefore, the quality of the resistance welded tube can be improved.

Abstract: PURPOSE:To provide a stable illumination with small change in intensity of electric discharge and emission of an electric discharge lamp by installing the electric discharge lamp which contains ionization medium and is placed in a wave guide tube through which microwaves are fed into a microwave oven. CONSTITUTION:Microwaves generated in a magnetron 1 are fed into a microwave oven's inside 20 through a coupling hole 8.

Filed: 1992-06-08
Abstract: PURPOSE: To enable a measuring of peak values of alternating voltage by determining a distribution function of a histogram corresponding to a probability that the alternating voltage exceeds respective amplitude values. CONSTITUTION: An ADD converter 1 converts an analogue alternating current fed to an input terminal 2 thereof to digital values. In sampling the alternating input voltage, values of respective storing positions of a memory 5 which are allocated to respective digital values are read on and fed to an adder 8. The sampling is repeated within a given time interval and an amplitude histogram of the alternating input voltage is provided in the memory 5. So called 'a distribution function of the histogram' corresponds to a probability that the alternating voltages exceed respective amplitude values which correspond to the alternating voltages and is obtained as an integration of the histogram.  An integration function which is an integration in a negative direction on the histogram is used for determining maximum peak values, while an integration function which is an integration in a positive direction is used for determining minimum peak values.
