Abstract: The present invention relates to an insulator as an insulating layer in a laminate which can inhibit dusting at the time of use, more particularly an electronic circuit component to which the insulator has been applied, particularly a wireless suspension. The insulator comprises a laminate of one or more insulation unit layers etchable by a wet process, the insulator having been subjected to plasma treatment after wet etching. The insulator exists mainly as an insulating layer in a laminate having a layer construction of first inorganic material layer—insulating layer—second inorganic material layer or a layer construction of inorganic material layer—insulating layer, and at least a part of the inorganic material layer has been removed to expose the insulating layer.

Abstract: It is possible to stably observe the temperature and/or composition of molten iron in a refining furnace by opening a tuyere for observation at all times according to the state of refining. There is provided a method of observing the inside of a molten metal refining furnace comprising the steps of: using a single tube tuyere for observing the temperature and/or composition of molten iron in the refining furnace via a tube penetrating refractories of a furnace wall and/or furnace bottom of the molten iron refining furnace by detecting electromagnetic waves radiated from molten metal at a forward end of the tuyere under a non-contact condition; and using an inert gas or an oxidizing gas, alone or mixed, according to the opening condition of the forward end of the tuyere.

Abstract: A magnetic head suspension includes an insulating base (12), wiring parts (13) formed on one surface of the insulating base (12) including a conductive metal layer, an elastic metal plate (14) provided on the other surface of the insulating base (12), and a wiring protecting layer (19) covering the wiring parts (13). The wiring protecting layer (19) is formed by subjecting a dry film containing an epoxy resin, an acrylic resin and a polymer containing aromatic rings to exposure and developing processes.

Abstract: A medium processing apparatus includes a medium feed path in a main body of an medium processing apparatus, a medium positioning mechanism provided in the main body of the medium processing apparatus adjacent to the medium feed path for causing a centering of the medium in the medium feed path, and a medium processing unit provided in the main body of the medium processing apparatus adjacent to the medium feed path, wherein the medium positioning mechanism forms a unit independent from the main body of the medium processing apparatus, and wherein the medium positioning mechanism includes an adjustment mechanism for adjusting a position of the medium positioning mechanism with respect to the main body of the medium processing apparatus.

Abstract: A sound emitting golf ball is provided for locating a golf ball after it is struct by a golf club. The system comprises a miniaturized electronic, battery powered piezoelectric sound generator surrounded by a shock absorber that is embedded inside a golf ball. The sound generating system is constructed with very small, inexpensive shock resistant components and embedded at the center of the golf ball inside the shock absorber. The system can be designed to operate in the audible or ultrasonic range.
