Title: Magnetic recording medium
Inventor: SHIGA AKIRA
IPC: G11B5/008
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To obtain a high output by making a medium into a magnetic record ing medium on which a signal is recorded and of which a difference between a signal output at the time of reproducing with a same speed as of recording and that at the time of reproducing with a speed two times as fast as of record ing is reduced. SOLUTION: In a magnetic recording medium having a magnetic layer famed on a tape form non-magnetic substrate, it is made possible to obtain a high output especially in frequencies of 20MHz or higher, by reducing a difference between a signal output at the time of reproducing with a same speed as of recording and that at the time of reproducing with a speed two times as fast as of recording. Here, it is preferable to use a signal of a wavelength of 0.50μm or shorter at the time of measuring a difference between outputs of recording and reproducing and it is recommended to select a wavelength so that a difference between the used signal and an output is within a range of 2.0-4.5dB.

Title: Arc welding method for groove width variation
Inventor: MORI SHINOYOSHI
IPC: B23K9/12
Filed: 1993-10-14
Abstract: PURPOSE:To change the relative welding speed for a work weld line and to maintain the bead height constant by detecting the arc voltage or a welding current to compare it with a reference value and reversing the operating direction of arc oscillation. CONSTITUTION:The welding current is detected and arc welding is performed by articulated robot and a controller for a groove part 1 of works M. Welding is started with the proceeding speed Vo and a proceeding angle alpha of a welding torch for a welding center line AB extending from a welding starting point A to a welding finishing point B. The arc voltage or the welding current is detected to compare it with the reference value and the operating direction of arc oscillation is reversed, by which the relative welding speed for the work weld line is changed and the bead height is maintained constant without changing the welding speed at the time of welding. Consequently, the bead height can be maintained constant without using a complicated arithmetic unit and further, weld line profiling also can be performed at the same time by performing groove width profiling.

Abstract: PURPOSE:To improve an efficiency of an engine by a method wherein an auxiliary coolant circulation passage is arranged in a main coolant circulation passage to be driven by the engine and the lubricant oil in the oil pan is cooled by an auxiliary evaporator in this auxiliary coolant circulation passage. CONSTITUTION:As an engine 1 is started to operate and a compressor 5 is driven, coolant is flowed in a main coolant circulation passage 4 so as to perform the function of the heat pump. When the temperature of the lubricant oil is reached the desired temperature or more by an oil temperature sensor 16 arranged in the oil pan 2, a solenoid valve 11 is opened by a control unit 17 and then the coolant is flowed in the auxiliary coolant circulation passage 15.

Title: Arithmetic unit for fuzzy inference
Inventor: ITO OSAMU
IPC: G06N7/02
Filed: 1986-10-31
Abstract: PURPOSE:To ensure adaptability of control by using a 1st memory which stores the consequent part fuzzy variable, a 2nd memory which stores the coefficient data on the consequent part membership function, and an arithmetic unit which carries out the consequent part arithmetic. CONSTITUTION:The largest one of valid degree alpha belonging to the same fuzzy variable is chosen and stored in the 1st memory 15 after grading. Then an arithmetic operation is applied last to said degree alpha. Thus the arithmetic time can be shortened compared with a case where all valid degrees alpha are calculated. While the 2nd memory 17 turns a consequent part membership function into a style in which a relevant function waveform is obtained by arithmetic with use of an existing relational formula based on the coefficient data if available. These coefficient data are stored for each consequent part membership. Thus the memory capacity can be greatly reduced in comparison with a case where a consequent part membership function is stored in the form of a group of many spot train data.
