摘要:
A dental catalyst for chemical polymerization comprising an acidic compound, an organic peroxide such as cumene hydroperoxide, and aryl borate compound such as sodium tetraphenylborate, but without substantially containing amine compound. This catalyst is chemically highly stable, is easy to handle, is highly active, is less likely to be impaired by polymerization, and does not cause the cured product to be tinted or discolored, and is very useful for the dental restorative.

摘要:
A metal clip for vehicle accessory fixation and a vehicle accessory installation structure using the metal clip, capable of improving a yield ratio of a metal plate required to form the metal clip and capable of reliably performing temporary fixation of accessories to an interior member. A metal clip (10) for vehicle accessory fixation has first V-shaped tabs (33) that are bent into a substantially V shape as seen from a side, an end edge of each of which V-shaped tabs (33) is an installation section (34) for engaging with a base section (12) of an accessory, and in which an engagement section (36a) for engagement with an installation hole of a vehicle panel is provided in the middle of each tab; an extension section (37) extended in a folding line (32) direction from a valley bottom section (31) of the first V-shaped tabs (33); and second V-shaped tabs (38) that extend from both sides of the extension section (37) in the direction crossing the extension section (37), each of which second V-shaped tabs (38) is bent in a V shape with an extension section (37) as the valley bottom section (31), and whose end sections (38a) engage with holes (51) of an interior member (50) to temporarily fix the accessory.
摘要:
A number of embodiments of crankcase ventilating systems for gas powered internal combustion engines employed in heat pumps. The crankcase ventilating system includes an oil vapor separator for separating and condensing oil from the crankcase ventilating gases and returning water vapor and the crankcase ventilating gases to the engine induction system for further combustion and purification. A number of various arrangements for controlling the temperature of the oil vapor separator are disclosed and an embodiment is disclosed that employs a pair of oil vapor separators acting in series.
摘要:
In dental crown restoration, a dental shade guide which is selected to match patient's teeth comprises a shade-guide portion and a handle. A molding device for molding the dental shade guide comprises a molding plate having a shade-guide molding portion and a handle-holding groove. The molding plate is closed by a cover. While the handle is held in the handle-holding groove of the molding plate, dental composite resin paste is filled in the shade-guide molding portion and the upper surface of the molding plate is tightly pressed by the inner surface of the cover.
摘要:
An engine-driven heat pump apparatus having a refrigerant circulation line which includes a pressure-measuring device for measuring the pressure in the refrigerant circulation line downstream of a compressor and upstream of an expansion valve, and an exhaust heat controller for controlling the exhaust heat from the engine based on the pressure by, for example, changing the heat efficiency of the engine, e.g., by controlling at least one of (a) the ignition timing of the engine, (b) the opening and closing timing of an intake port valve and an exhaust port valve, and (c) the opening of a fuel gas-controlling valve, so as to efficiently increase heating power during heating operation at low temperatures, without increasing engine noise or shortening the life of the engine.
