A liquid for setting dental cements comprising a aqueous solution of a copolymer of acryclic acid and maleic acid, tartaric acid and one or more fluorocomplex salt.
摘要:
A liquid for setting dental cements is provided, in which an aqueous solution of a copolymer of acrylic and maleic acids contains a tetrahydrofurantetracarboxylic acid alone or in combination with at least one of tartaric acid, a fluorocomplex salt and a specific organic carboxylic acid. The specific organic carboxylic acid is expressed by the general formula:C.sub.m H.sub.n (COOH).sub.x (OH).sub.y

The slide operation-type dovetail groove sliding stage may include a sliding lock screw for locking sliding of a sliding component, by causing the screw to abut on an inverted triangle-shaped protrusion, provided on a sidewall of a sliding component approximately parallel to a sliding direction and coupled to the sliding component, to bring the protrusion into contact with a dovetail of the fixed component and by tightening the screw. The sliding lock screw may be used as a sliding adjustment screw for performing fine adjustment of a degree of sliding of the sliding component with respect to the fixed component by adjusting an amount of rotation of the screw which abuts on the protrusion to bring it into contact with the dovetail of the sliding component, and a driving means which an operator grasps to perform an operation of sliding the sliding component to a desired position.

A failure detection system detects a failure occurring in an exhaust secondary air supply system of an internal combustion engine, and has a catalytic converter installed in an exhaust pipe of an exhaust system of the engine for reducing pollutants from exhaust gases emitted from the engine, a conduit connected, at one end, to the exhaust pipe at a location upstream of the catalytic converter and an air pump connected to an opposite end of the conduit for supplying compressed air in the conduit. The conduit is closed by the a valve which opens in response to the negative pressure and a second valve which opens in response to the conduit pressure. In the system a first prescribed level and the second prescribed level are set and two pressure switches are provided for generating output at the levels. A failure occurring in the air pump and the valve is detected based on operation of the air pump and the output of the pressure detectors. Alternatively, the failure is detected by changing the timing of the termination of the air pump and closing of the second valve while using one switch and the second prescribed level. The system is simple in configuration.
摘要:
A system for controlling an idle speed of an internal combustion engine having an electrically heated catalytic converter which is heated up when current is supplied from an alternator driven by the engine. In the engine idle control, a basic value of a desired idle engine speed is determined with respect to the engine coolant temperature in the same manner as the prior art. However, an augmentative correction amount of the desired idle engine speed is determined with respect to the exhaust system ambient temperature. More specifically, the desired idle engine speed is increased in response to the heating of the catalytic converter so as to prevent the alternator from generating electric power insufficient for heating up the catalytic converter.

With conventional protective sheets for displays, a space corresponding to the size of a hand is formed between the protective sheet and the display face, and thus it takes more time to bring the exposed face and the display into close contact, which increases the probability of dust contamination. There is also a problem that if the protective sheet were made from a highly rigid material, a space into which a hand could fit would not be produced.In order to solve the above problems, in the present invention, a sheet affixing structure is provided, which is characterized in that a release sheet that is provided on an adhesive face of a protective sheet main body comprises two separate sheets, these being a first sheet and a second sheet, wherein the second sheet has a folded structure and one part of the folded free portion protrudes beyond the protective sheet.
摘要:
An evaporated fuel control system in internal combustion engines includes a canister filled with an adsorbent for adsorbing an evaporated fuel in a fuel tank, a purge amount control device provided in the middle of a purge passage connecting an intake passage and the canister, and a fuel supply device. The purge flow rate from the start of purging is integrated, and the purge amount is reduced to a larger extent in response to a purge amount integration value becoming smaller. This improves the nature of an exhaust gas immediately after the start of purging and the like.
