Title: Thermal transfer recording method
Inventor: HASEGAWA TETSUO
IPC: B41M5/398
Filed: 1986-03-07
Abstract: PURPOSE:To transfer record a favorable image at low recording cost, by applying energy patternwise to a supercoolable thermally transferrable ink layer of a thermal transfer material to melt or soften a thermally transferrable ink, laying the transfer material on a recording medium, and transferring the softened ink onto the recording medium under pressure. CONSTITUTION:A thermal transfer material 3 comprising a layer 2 of a supercoolable thermally transferrable ink on a base 1 consisting of a metallic sheet is fed rightward. When thermal energy according to a desired image pattern is supplied to the transfer material 3 from the side of the ink layer 2 by a thermal head 4, the ink constituting the ink layer 2 is thermally melted or softened, and becomes tacky, thereby having ransferrability. Since the ink is supercoolable, it remains in the thermally melted or softened state even after the heating by the head 4 is completed, and is fed further leftward as the transfer material 3 is fed. Accordingly, the shape of the melted or softened pattern of the ink is maintained, and fidelity of the pattern to a heat supply pattern is maintained.

Title: Air-fuel ratio control for combustion equipment
Inventor: KOISHIKAWA ATSUSHI
IPC: F23N5/00
Filed: 1982-03-30
Abstract: PURPOSE:To improve response and to obtain the optimum burning condition in a combustion equipment, by correcting a set target value of oxygen consentration by an actually measured concentration of unburned gas and an actually measured fuel flow rate. CONSTITUTION:The oxygen concentration in exhaust gas and that in unburned gas actually measured by an unburned gas concentration detector 11 are linearized and converted into electric current by a converter 12, and are put into an air-fuel ratio controller 13. On the other hand, a set target value of oxygen concentration O2S1, a correction value O2S2 which is determined from an actually measured concentration of unburned gas, and a correction value O2S3 which is determined from an actually measured fuel flow rate, are processed in an adder 14, and the result is also put into the air-fuel ratio controller 13 as a target value of oxygen concentration O2S. The air- fuel ratio controller 13 puts out the air-fuel ratio of which difference between the target value of oxygen concentration O2S and the actually measured oxygen concentration is small, and the output is put into an air-fuel ratio multiplier 7. By this method, the target value of oxygen concentration is automatically controlled to the optimum value, and the response is improved, so that the optimum burning condition can be obtained in a combustion equipment all the time.

Title: Eddy current flaw detection method and apparatus
Inventor: KIMOTO SANSHIRO
IPC: G01N27/90
Filed: 1988-03-02
Abstract: PURPOSE:To enable accurate determination of a phase angle necessary for calculating a thickness reduction rate, by storing a wavelength of a sine wave and pulse widths of first and second control pulses previously into a memory means in such a manner that a ratio between the wavelength and the pulse widths gives a fixed value all the time. CONSTITUTION:Synchronous detectors 17 and 19 serve as integrated value computing means and an output means. Outputs of the detectors 17 and 19 are both inputted into a sensitivity adjustor 21 and then, into 90 deg. fixed phase devices 25 and 27 cleared of an excess of electrical signals such as noise through a filter 23. An output of the phase device 25 is amplified 29 to be outputted as Y-axis component while that of the phase device 27 is amplified to be outputted as X-axis component. Then, a wavelength of a sine wave and pulse widths of first and second control pulses are stored previously into a memory means in such a manner that a ratio between the wavelength and the pulse widths gives a fixed value all the time while the first and second control pulses differ by pi/2 in the phase. Thus, an impedance change generated in a test coil can be determined accurately thereby enabling accurate determination of a phase angle necessary in the calculating of a thickness reduction rate.
