Abstract: An arrangement for controlling a waste shot of a die casting machine. Data are entered and stored in a memory data defining waste shot mode and normal shot mode operations of the die casting machine. The machine is then operated in normal shot mode. By monitoring various parameters, it is determined whether the die casting machine is operating in accordance with the data defining normal shot mode operation. In the event that the die casting machine is not operating in accordance with the data defining normal shot mode operation, the machine is stopped. After stopping, the die casting machine is restarted and automatically operated in waste shot mode in accordance with data previously stored, and then automatically operated in normal shot mode in accordance with data previously stored.

Abstract: An accelerator pedal assembly for use in a motor vehicle includes an elongate pivotal lever which is pivotally supported at its generally middle portion by a pivot shaft. The lever has thus upper and lower portions which are pivotally mounted to the lower portion of the lever. The upper end of the lever has a circular recess to which an accelerator cable is connected. The lever is equipped at the upper portion with a damping mass (or weight) for suppressing the undesired resonant vibration of the lever. The damping mass is so positioned that a center of gravity "G" of the damping mass is placed on an imaginary straight line "L" which passes through both given points "P" and "Q", the point "P" being the center of the pivoted middle portion of the lever and the point "Q" being the center of the circular recess of the lever. Thus, when the pedal is depressed, an inertial force of the damping mass does not produce a torsional stress in the lever because of no moment produced around the line "L".

Abstract: A phased-array radar capable of electronically directing a directional beam of an antenna in any of N different directions, i.e., direction .theta..sub.1 to direction .theta..sub.N. Scanning of the directional beam is effected in any of a long-range mode for detecting and tracking a target cruising at a long range from the radar and a short-range mode detecting and tracking a target cruising at a short range. This reduces the data rate and thereby increases the target information updating frequency associated with a short-range target.
