IPC: B01D35/02
Filed: 1986-12-01
Abstract: PURPOSE:To comparatively easily detect the presence of an O-ring fitted to the inside of an oil filter by performing complete tightening after temporary tightening and measuring the time required to perform complete tightening and comparing this time with the reference time preset properly. CONSTITUTION:A cartridge type oil filter A is clamped with a clamping device so that an O-ring B automatically fitted to the end part of the filter A is closely stuck to the bearing surface D of the part fitting the filter of an engine. In this case, after temporarily tightening the filter A, it is completely tightened and also the time required to perform complete tightening is measured and this time is compared with the reference time preset properly and thereby the presence of the O-ring B fitted to the inside of the filter A is detected. In other words, when the above-mentioned time required to perform complete tightening is longer than the reference time, the O-ring B is fitted to the filter A and when the time is shorter, the O-ring B is not fitted.

Filed: 1988-11-11
Abstract: PURPOSE:To perform gradation expression due to area modulation and to obtain stable medium contrast recording by providing a separation electrode not in contact with a common electrode and a signal electrode on a heating resistor. CONSTITUTION:A common electrode 2 and a signal electrode 3 are provided to both terminals of a heating resistor 1 to be connected to a driving element 50 for turning the current to the heating resistor 1 ON and OFF. A circular separation electrode 13 is formed to the center of the heating resistor 1. By this method, the current route of the heating resistor 1 flows from the common electrode 2 to the separation electrode 13 and subsequently flows from the separation electrode to the signal electrode 3 when the potential of the common electrode 2 is higher than that of the signal electrode 3. Therefore, when the shape of the separation electrode is narrower than the common electrode or the signal electrode, current density becomes max. in the periphery of the separation electrode, especially, at a place near to each electrode and, in the temp. distribution on the heating resistor at this time, temp. becomes peak at a place near to each electrode in the periphery of the separation electrode. Corresponding to the temp. distribution, heat-meltable ink is melted and a transfer area at the time of the transfer to recording paper changes as shown by Fig c.
