Abstract: A subband encoding and a decoding system are provided. The subband encoding system measures signal levels of subband signals to determine scale factors to obtain scale factor information and produces bit allocation information based on the scale factor information, scale factor flag information indicating the fact that the scale factor information has changed from that one frame earlier, and updated scale factor information indicating the scale factor information which has changed from that one frame earlier. The subband encoding system re-quantizes the subband signals using the scale factor information and the bit allocation information to provide re-quantized output signals and constructs as an encoded output signal a frame made up of the re-quantized signals, the updated scale factor information, and the scale factor flag information. The number of subbands of the subband signals to be re-quantized is determined by an upper limit frequency of an audible band. This results in a decrease in operation load of the subband encoding and decoding systems.

Abstract: There is provided a construction for a cam rotation sensor attaching portion where a cam rotation sensor is attached which detects the rotation angles of camshafts (1, 3) supported on cam holders (lower cam holder 12, upper cam holder 13), the construction being characterized in that portions to be detected (projections 18) are provided on thrust plates (17) fixed to axial ends of the camshafts so as to be brought into abutment with an axial end face (a thrust receiving face 31) of the cam holder for regulating axial positions of the camshafts, and that a sensor (a proximity sensor 23) for detecting the passage of the portions to be detected from an axial direction of the camshafts is attached to a member (a sensor attaching wall 20) which is integrated into the cam holder. According to this construction, since the relative positioning accuracy between the portions to be detected and the sensor attaching portion with respect to the axial direction of the camshafts can easily be improved, a high detection accuracy can be obtained. Moreover, since the sensor and the head cover can be attached to and detached from the cylinder heat; without affecting each other, the maintenance and servicing properties thereof can be enhanced.

The handle is assembled to the housing with the pivot pin extending through the pivot opening. A bushing may be disposed between the pivot pin and the pivot opening to take up tolerances between the parts and provide smooth handle rotation. The drive pin on the crank extends into a drive slot on a slider which translates within the housing to actuate a wind ow locking mechanism. The drive slot is generally pear-shaped with, preferably symmetrical, oppose d cowed sidewalls along which the drive pin rides during rotation of the handle. The slider ma y further include a pair of fulcrum tabs disposed on a top thereof adjacent opposite sides of the dri ve slot for contacting a side surface of the crank during rotation of the handle to provide mechanica l advantage at the handle. A spring is provided with a bowed middle portion which extends benea th the slider and identical ends which extend above the slider at each side thereof. One end o f the spring provides the detent function by biasing the drive pin against one of the slider side walls. The other end of the spring extends upward to provide pick resistance by forming a physical barrier between a slot in the base portion of the housing and the crank, handle, and bushing. The actuator may be converted for single-point use, by providing a single point extension on the slider, either integrally or as a separate part. The single point extension has a latch opening for receiving a latch of a single-point locking mechanism during rotation of the handle. The latch opening may be defined by a pair of symmetrically curved arms which force the latch into the openin g, and which provide non-handedness.
