Title: Ion current recording head and manufacture thereof
Inventor: YAMAOKA TOSHIHIDE
IPC: B41J2/415
Filed: 1990-08-10
Abstract: PURPOSE:To produce an electric field in a size large enough for controlling of allowing and checking of passage of ion current by the application of a comparatively low voltage by a method wherein a hole for passage of the ion current is provided to a layered body that is made of a pair of electrodes placed facing each other on the opposite faces of an insulating substrate, and the hole for passage of the ion current is divided into a plurality of holes. CONSTITUTION:In the case where a hole 34 for passage of ion current is divided into a plurality of holes 34a, 34b, an electrode becomes to exist in the center of the hole 34, and thereby an electric field is produced there. Because of this, it becomes possible to produce an electric field in a necessary size extending over the whole area of the hole for passage of the ion current even with application of relatively low voltage. When a voltage condition which makes the ion current pass through the hole is given, the ion current is converged by effect of electrostatic lens and because of this, the amount of the ion current passing through the hole does not decrease even if the electrode exists on the inside of the hole for passage of the ion current.

Filed: 1989-08-18
Abstract: PURPOSE:To easily know the usable amount of iron in which ironing can be continuously done without feeding by providing a means for informing the difference of present temperature to the prescribed temperature of a base face as a usable amount in an iron main body. CONSTITUTION:An iron main body has a power source comprising a condenser for operating a control means during ironing and a battery or the like and a feeding terminal electrically connected to a heater. When the temperature of a base 2 gradually falls due to ironing, the control means sequentially puts out a light of LED of an informing means indicating a usable amount based on an output of a temperature detecting means to inform an operator of a feeding time of an iron main body 1. Thus, since the usable amount can be informed, the feeding time of the iron main body 1 can be informed to the operator. Accordingly, the operator can devote himself to ironing without worrying about the fall in temperature of the iron main body 1 or the feeding time and therefore operability is improved.
