A thermal printer head comprises an array of heating elements (1-1.about.1-N) mounted on an insulating base member (20). Each of the heating elements is connected to a common voltage source (V) and has a temperature dependent electrical resistance. Electrically resistive elements (2-1.about.2-N) are respectively connected in series with the heating elements to form a plurality of series circuits. Current supply circuits (3-1.about.3-N, 4-1.about.4-N, 5, 6, 7-1.about.7-N, 14) are provided corresponding respectively to the resistive elements for selectively supplying a current to the series circuits in response to a sequence of print signals. A control circuit (8-11, 14) makes a determination whether a voltage developed across each resistive element is higher or lower than a prescribed threshold value and causes one of the current supply ciruits corresponding to the resistive element to control the current depending on the determination.

A resin composition is described consisting essentially of from 0.5 to 100 parts by weight of a water-soluble polyamide and from 0.5 to 100 parts by weight of a vinyl alcohol-based polymer. The resin composition has excellent transparency and can be used, for example, to form light-sensitive resin compositions and adhesives.
摘要:
Although a method for changing a combustion method taking place in an internal combustion engine depending on running condition is proposed, it can be considered that conditions under which a combustion noise occurs naturally differ with different methods. A detection method of prior art is not compatible with different combustion methods and the accuracy of combustion noise detection was low. Accurate combustion noise detection is enabled by identifying a combustion mode taking place in the internal combustion engine, selecting a sensed frequency or frequency band of a combustion noise sensor that detects a combustion noise in a combustion chamber of the internal combustion engine according to the combustion mode, and detecting a combustion noise.

Provided is a control device of a direct injection engine, the control device that can prevent the amount of emission of soot from increasing and the exhaust performance from worsening when a restart request is made before an engine is stopped after an idle stop condition is satisfied. When a restart request is made before an engine is stopped after an idle stop condition is satisfied, at least one of the number of fuel injections in one combustion cycle and the air/fuel ratio of an air fuel mixture used for combustion is changed for each cylinder according to a piston position at that time.
