This equipment is remarkable in that the or each core possesses an insert (I) secured to the core while making said core and via which said core is suitable for co-operating with the mold element in question. The invention also provides an associated method of positioning cores. The invention is particularly applicable to improving the positioning of admission pipes in light alloy cylinder heads for engines.

    摘要: A write clock generation circuit is provided that can detect wobble signal in high accuracy and can appropriately generate write clock with only small jitter even when the operation is switched from reproduction to recording. The wobble signal is obtained by changing stepwise the gain of a variable gain amp in the rear stage of a divided photo detector using a gain control circuit in a predetermined time period just after the beginning of recording. The write clock signal is generated using the above wobble signal. According to this arrangements, the change in wobble signal just before and after the beginning of recording can be reduced, and the gain change of a wobble signal amplitude regulation AGC is made slow. As a result, high frequency deviation of the wobble signal can be reduced even when the operation is switched from reproduction to recording, and the write clock with only small jitter can be generated.

    摘要: A self-injection device has a tubular sleeve which is open at its posterior end and partially closed at its anterior end. An ampule sealed at its posterior end by a piston and at its anterior end by a membrane is axially arranged within the tubular sleeve. An injection needle having a terminal flange at its posterior end and an anterior end for piercing the membrane is axially arranged in the ampule. A tubular actuating cap having a piston rod emanating from the bottom of cap for acting upon the piston is slidably guided on the sleeve. The actuating cap and the piston rod are traversed by a central bore having axially extending grooves. The device also includes a locking pin having radially projecting spring tongues. A first segment of the spring tongue extends in an axial direction on the periphery of the locking pin and a second segment is bent at an obtuse angle, extending obliquely outward in a radial-axial direction through the axially extending grooves in the central bore. When fully inserted into the device, the spring tongues contact the posterior end of the sleeve to prevent unintentional triggering of the injection needle.

    摘要: The invention is directed to a process for plating Al alloys containing lithium by hot co-rolling under the usual heating conditions, in the air. The process comprises effecting controlled oxidation of the core alloy by heating in the air at between 450.degree. C. and 550.degree. C. for a period of time such that the depth affected by the surface loss of Li is between 50 and 700 .mu.m. The core is then treated mechanically or chemically to remove the surface oxides with a loss of alloy less than 30 .mu.m. An assembly of the core and platings is then co-rolled with reheating to a temperature of less than 500.degree. C. for less than 24 hours. The result is perfect adhesion of the core to the surface platings.
