摘要： A casing assembly for electronic equipment comprising a printed circuit board on which an exothermic electronic component is mounted, a casing for covering the printed board, and a base for attaching the casing to a wall body or a rail. The base is of a high heat conductive material and has a planar structure which results in a large contact area between it and the wall body or rail. A high heat conductive plate like cushioning member made of an electrically insulative material is interposed between the board and the base in contact therewith. The heat generated in the electronic component is released through the printed board and lead wires and through the cushioning member and the base to the wall body or rail. Preferably, where the casing is attached to the rail, a guide latch member and a pressure latch member are attached to the base. Where an auxiliary printed board is provided in addition to the printed board, the base, the printed board, the auxiliary frame and the auxiliary printed board are stacked in that order and covered with the casing. Where a programmer is attached to the casing, provision is made for attaching in either the horizontal or vertical direction. Where the functions of a basic module is insufficient, extended modules may be connected.

摘要： A valve timing control apparatus for an internal combustion engine can be improved in accuracy in the detection of valve timing (cam angles). A crank angle sensor generates a crank angle signal in the form of a train of pulses. Cam angle changing parts change phases of camshafts relative to a crankshaft. Cam angle sensors generate cam angle signals. A reference crank angle detection part detects reference crank angles based on the crank angle signal. Cam angle calculation parts calculate the cam angles of the camshafts based on the crank angle signal and the cam angle signals. A cam angle control part controls the relative phases of the camshafts to the crankshaft so as make them coincide with target cam angles corresponding to operating conditions of the engine. A cam angle calculation part calculates the cam angles by counting the number of pulses of the crank angle signal.

摘要： An elevator car and a counterweight is suspended on a sheave by means of a rope in a well-rope faashion. In dependence on the number of passengers on the car, the sheave is applied with an unbalance torque making appearance between the car and counterweight. Upon starting of the elevator operation by releasing a brake, upward or backward bouncing of the car takes place due to the unbalance torque. For preventing such bouncing of the car, a start compensation is performed by generating a motor torque which can cancel out the unbalance torque in precedence to the releasing of the brake. The brake is installed swingably on a winding equipment. Displacement of the brake during actuation thereof indicates the presence of the unbalance torque. By taking advantage of this displacement, the start compensation is carried out by increasing the motor torque progressively in the direction depending on the displacement and by holding the motor torque constant at a value attained when the displacement becomes smaller than a predetermined value.
