Title: Air/fuel ratio detector
Inventor: AOKI KEIICHIRO
IPC: G01N27/41
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent the situation in which element impedance is erroneously detected when the output current of an air/fuel ratio sensor becomes a value impossible to measure and element temp. rises excessively in a case holding the air/fuel ratio sensor to an active state, by detecting element impedance from AC characteristics to feed back the same to control a heater. SOLUTION: An output current value I of an air/fuel ratio sensor is detected, and it is judged whether the output current value does not become the upper limit value (lean side limit value) IUL due to the restriction of a drive circuit or more or the lower limit value (rich side limit value) ILL or less. When the sensor output is neither inclined to a lean side nor also to a rich side, element impedance Z is calculated and feedback control determining the feed power to a heater on the basis of the element impedance is performed. When the sensor output becomes the state inclined to the upper limit value IUL or the lower limit value ILL, the feed power to the heater is determined by open loop control.

IPC: B41M5/36
Filed: 1995-02-09
Abstract: PURPOSE: To enhance the close adhesiveness of an anchor layer or a protective layer by adding an org. monomeric compd. to a recording layer and preventing that the surface of the recording layer is covered with the film of the org. monomeric compd. CONSTITUTION: A raw material 60 obtained by coating the surface of a base material with a recording layer containing a resin matrix and an org. monomeric compd. is immersed in a water tank 10 from the upstream side of the water flow generated on the surface of the water and drawn up above the surface of the water from a downstream side. The raw material 60 is dried after the recording layer is applied and a solvent is evaporated and the org. monomeric compd. is precipitated on the surface of the recording layer and dissolved or semi-dissolved to be not crystallized.  Therefore, when the raw material 60 is immersed in the water tank 10, water penetrates into the gap between the resin matrix on the surface of the recording layer and the org. monomeric compd. and the org. monomeric compd. is released from the surface of the recording layer and cooled at the same time to be crystallized and the membrane 80 of the org. monomeric compd. floats to the surface of the water. By this constitution, the org. monomeric compd. can be easily removed from a recording surface and the close adhesiveness with a protective layer can be enhanced.

Abstract: PURPOSE:To permit the conductive coupling of metal and metal foil as well as the removal of resin layer by the procedure in which base metal and metal foil are temporarily jointed with a non-conductive resin layer, and then pressurized while applying supersonic vibration. CONSTITUTION:The metal foil 9a is laid over the base metal 10a through the non- conductive resin layer 9b, and then the chip 1 with the uneven pressure surface 1a is pushed against the metal foil 9a and applied a supersonic vibration from a vibrator. Thus, the resin layer 9b below the convexed portion is removed by the application of pressure and transverse vibration to the convexed portion, while the resin layer 9b removed from the adjacent convexed portion flows into the resin layer 9b below the concaved portion, whereby the copper foil 9a comes into contact directly with the base metal 10a in the convexed portion of the chip 1, assuring good conductive coupling with the aid of the heat of friction resulting from supersonic vibration.
