IPC: C21D9/46
Filed: 1980-05-07
Abstract: PURPOSE:To obtain a steel plate of high surface quality by heat treating a low- carbon cold rolled steel plate under a specified condition and thereby eliminating formation of oxide during the process of heating. CONSTITUTION:The cold rolled steel plate is soaked for >=10sec within a temperature range of Ac3 point from the recrystallization temperature in the nonoxidizing atmosphere using a radiant heat heating furnace. Next, the steel plate is quenched by immersing in a refrigerant of water. Then, the plate is taken out and reheated to 350-500 deg.C and overaged for >=30sec in a nonreducing atmosphere. The overaged steel is cooled and pickled to clean the surface of the plate. By this method, the formation of oxide on the surface of the steel plate is eliminated and the adhesion of  oxide to the roll is prevented. Thus, pickling process can be made simple and a steel plate of good surface quality is obtained.

Title: Cylinder piston device
Inventor: MATSUBARA KOSUKE
IPC: F16F9/096
Filed: 1987-03-16
Abstract: PURPOSE:To reliably select the damping force with use of a compact motor, by providing a rotary valve rotatably engaged with a valve housing and adapted to be rotated by a stepping motor, which rotary valve has an oil passage communicatable with a second oil chamber. CONSTITUTION:When a stepping motor 41 is rotated at a predetermined angle according to a driving pulse, a pressure balance port 51 of a rotary valve 38 is brought into communication with a communication hole 53 of a valve housing 35, thereby communicating an oil passage in the rotary valve 38 with a second oil chamber 11b. When a rod 3 is axially moved relative to a cylinder 2, the oil is allowed to flow between a first oil chamber 11a and the second oil chamber 11b through the communication hole 53 and the balance port 51. The movement of the rod 3 is damped according to an opening degree of the communication hole 53 variable with the rotation of the rotary valve 38. The stepping motor 41 is used in the oil, and no seal is required between the oil chambers 11. Therefore, it may be smoothly rotated without sliding resistance, and a damping force may be reliably selected regardless of the compact motor.

Title: Reproducing magnetic head
Inventor: MATSUYAMA HIDEO
IPC: G11B5/39
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain reproducing magnetic head suitable for high density which does not extremely reduce the reproduced signal even when a magnetic field detecting section is reduced in size for high installation density by forming the magnetic detecting section with a magnetic material and a means for detecting temperature of the magnetic material. SOLUTION: A magnetic head is formed on single surface of a slider 12 using an insulating material having a small thermal conductivity as a supporting film 11. A magnetic film 9 is arranged on the supporting film 1 and is shaped so that the magnetic thin film 9 and supporting film 11 becomes flat in their surfaces. On his magnetic thin film 9, a semiconductor thermo-couple 10 having a large thermal electromotive force, for example, is formed and a contact of the thermo-couple 10 is led on the magnetic thin film 9. Patterning is conducted so that the contact of the other end of thermo-couple and the lead wire 13 is set to the same temperature. When the magnetic head is relatively moved on a medium, a leakage magnetic field from a medium is impressed to the magnetic thin film 9 and magnetization 14 in the magnetic thin film 9 is simultaneously inverted.  With inversion of magnetization 14, energy consumption occurs and temperature of magnetic thin film is raised a little and this temperature rise is detected by the thermo-couple 10 as a reproducing signal.

Title: Treatment of waste solution containing caustic cyanide and metal
Inventor: BURUUSU ERU BURANDENBAAGU
IPC: C02F5/00
Filed: 1989-03-13
Abstract: A method for operating a continuous wet oxidation system for destroying cyanide in caustic cyanide and metal wastes which scale upon heating comprises introducing raw waste into the wet oxidation reactor (14) without heating while a mixture of heated dilution water and oxygen containing gas is introduced into the reactor by a separate inlet (12). The reactor (14) is fitted with a pair of valved effluent lines (16,17) and corresponding valved lines (44, 50) for introducing dilute mineral acid into each effluent line at system pressure. Oxidized effluent and offgases exit through a first effluent line (16) while dilute mineral acid flows through the second effluent line (17) into the reactor to prevent scale buildup. Periodically the flows are switched such that oxidized effluent and offgases exit through the second effluent line (17) and dilute mineral acid flows through the first effluent line (16) into the reactor to remove scale. The oxidized effluent and offgases are then cooled and separated.

Abstract: PURPOSE:To eliminate a level shift in an information variation point irrespective of whether a cable transmission distance is long or short by transmitting a mark and the code of a space or a space and the code of a mark which are bisected immediately after information is varied. CONSTITUTION:A microcomputer 1 sets a mark signal (a) and a space signal (b) as pause bits to an off-state for a prescribed time or longer, and transmits '1' and '1' as synchronizing bits, therefore, in the first half of each, the space signal (b) is turned on, and in the latter half, the mark signal (a) is turned on. Since its next information is variation information to '0', the first half part is bisected and the space signal (b) is turned on and off, and the mark signal (a) is turned off and on, and thereafter, in the latter half, the space signal is turned on. In such a manner, based on a receiving signal when the latter half part of a receiving waveform is always the most stable, the receiving operation is repeated, and information being inter-device data is transmitted to a microcomputer 9.

Filed: 1990-03-14
Abstract: PURPOSE:To speed up the processing of a vector computer by preventing the same index value from continuing and change a way of setting an array, a generating method for a list, and calculation order for longer vector length in arithmetic regarding a space matrix. CONSTITUTION:The vector length is made long and IF sentences are removed by adding zeros before and after a vector by which a regular space matrix is multiplied as many as required. Further, column numbers are given, row by row, in the multiplication of an irregular space matrix and the vector and index values which are larger than (n) are used cyclically for indexes corresponding to the zero parts and replaced laterally when the same index value continue. For example, a matrix A which is discretized by a three-dimensional difference method is multiplized by a vector X and the result is put in a vector Y. In this case, the matrix and vector are as shown in a figure. Consequently, fast calculations are made by the vector computer.
