    Abstract: An ultrasonic Doppler blood flow meter comprises a transmit-receive transducer transmitting ultrasonic wave toward and into a living body and receiving an echo signal, quadrature detectors detecting a real (R) component and an imaginary (I) component of the receiving echo signal respectively, A/D converters converting analog output signals of the quadrature detectors into digital signals respectively, a converter subjecting the R and I components to quadrature transformation to generate output signals representing the absolute value and phase angle (.theta.) respectively of the received echo signal, and a signal processing circuit calculating the mean value of the differences (.DELTA..theta..sub.i =.theta..sub.i -.theta..sub.i-1) between the phase angles (.theta..sub.i) and their preceding ones (.theta..sub.i-1) detected when the ultrasonic wave is transmitted and the echo signal is received a predetermined number of times. In the signal processing circuit, the phase angle differences (.DELTA..theta.) are each resolved into an X-axis component (cos .DELTA..theta.) and a Y-axis component (sin.DELTA..theta.), and, after calculation of the mean values X and Y of n consecutive X-axis and Y-axis components respectively, the mean Doppler shift phase angle .DELTA..theta.=tan.sup.-1 (Y/X) is calculated on the basis of the calculated mean values X and Y.

    Abstract: A rocker arm supported by a support portion of an engine and to be driven by a cam includes a sheet-metal rocker arm body manufactured by plastic working and including a cam follower, a fulcrum portion manufactured by cutting and including a through hole supplying lubricant, and a lubricant discharging hole. The cam follower includes a first slide-contact surface being in sliding contact with the cam. The lubricant discharging hole is defined by an outer surface of the fulcrum portion and an outer surface of the sheet-metal rocker arm body and in communication with the through hole. The lubricant discharging hole biases the lubricant supplied from the through hole in a direction toward the first slide-contact surface.

    Abstract: A hydraulic lash adjuster for an internal combustion engine is disclosed. The hydraulic lash adjuster includes a low-pressure chamber defined in the plunger and filled with a hydraulic fluid and a high-pressure chamber filled with hydraulic fluid defined in a lower interior of the cylinder and partitioned by the bottom wall of the plunger from the low-pressure chamber. A valve port is formed through the bottom wall of the plunger so as to communicate with both the low-pressure and high-pressure chambers. The valve port has at the high-pressure chamber side an opening edge formed with a valve seat face. A valve element is provided in the high-pressure chamber so as to abut and depart from the valve seat face, thereby closing and opening the valve port. The valve element is made of a material having a specific gravity smaller than steel.
