Patent EP-0333460-A2 (EP)
Inventor: CALKINS EUGENE E
IPC: B27B17/08
Filed: 1989-03-15
Abstract: A sprocket assembly including a sprocket adapter driven by the motor of a chain saw. The adapter includes an adapter shaft (24) which has a defined inner opening to fit around the drive shaft (18) of the chain saw. A sprocket (28) is mounted on the adapter shaft (24). Splines (26) on the adapter shaft exterior fit into spline grooves (30) of the sprocket (28). The thickness (27) at the roots of the splines (26) provide the strength to resist breakage. The exterior areas of the adapter shaft (24) between the splines are flat landings (46) which define relieved thickness areas between the splines (26) and are aligned with tang-receiving pockets (42) in the sprocket (28). The relieved areas (46) permit an optimum sizing of the sprocket (28) to the saw chain with sufficient pocket depth to fully receive the drive tangs (38) of a saw chain. The sprocket rims (40) are provided with mated inner edges (50) that mate to the flat landings (46) of the adapter shaft (24) to facilitate transmission of the turning power from the drive shaft (18).

Title: Improvements in or relating to methods of manufacturing tube coupling bodies
Inventor: GUEST JOHN DEREK
IPC: F16L37/092
Filed: 1989-03-22
Abstract: The disclosure relates to a method of manufacturing a tube coupling body (10) in a plastics material using injection moulding tooling. The body is formed with a cylindrical bore (11) having enlarged end portions (13) in a mould body (15) and using removable cores (17). The cores form both the internal bore of the mould body and also end parts of the mould body so that once the cores are removed, end parts (13a) of the coupling body are revealed in the mould. Whilst the end parts are still hot from the initial moulding operating, forming dies (20) having tapering end cavities (21) are pressed over the end parts of the moulding to form the end parts of the moulding with both external and corresponding internal tapered surfaces. The tapered internal surfaces of the end parts thus formed provide tapered cam surfaces for engaging the resilient arms of collets to be inserted in the coupling body to receive and lock tubes in the coupling body.

Abstract: An electret condenser microphone includes a cup-­shaped metallic case (11) having an apertured end wall (11a), a tubular metal ring (12) received in the metallic case (11), a vibratory diaphragm (13) having on its one surface a deposited metal film (13a) and bonded to an end face of the tubular metal ring (12) in confronting relation to the end wall (11a) with an air gap (19) defined therebe­tween, and a condenser composed of a movable electrode and a fixed counter electrode, the fixed counter electrode com­prising at least a part of the end wall (11a) of the metal­lic case (11) while the movable electrode comprises the vibratory diaphragm (13). Partly because the end wall (11a) of the metallic case (11) serves as the fixed electrode, and partly because the vibratory diaphragm (13) is bonded to the end face of the metal ring (12), the number of the compo­nents of the microphone is relatively small. With this small number of components, the microphone is simple in construction and can be manufactured at a low cost, and further has a relatively large rear cavity (14) behind the vibratory diaphragm (13), which improves the sensitivity of the microphone.

Abstract: Frequency division multiplex signal lights (1) are propagated through an optical fiber (10), and polarizations of the lights are collectively controlled by a polarization controller (2). The polarization-controlled signal lights are received separately in receiving systems (4, 5, 6), including optical heterodyne or homodyne receivers (11). In the collective polarization control, a step is selected from steps of controlling relative polarization states of local oscillation lights to coincide to each other, receiving a control signal from one of the receiving systems which receives a signal light of a frequency to be allocated in the center of a frequency band of the signal lights or the vicinity thereof, and dividing the frequency division multiplex signal lights into plural groups, thereby controlling polarizations collectively in each of the plural groups. One of the polarizations of the signal lights may be orthogonal to the others, and one of the polarizations of the local oscillation lights may be orthogonal to the others correspondingly.

Abstract: Herein disclosed is a multiprocessor system which comprises first and second processors (1001 and 1002), first and second cache memories (100:#1 and #2), an address bus (123), a data bus (126), an invalidating signal line (PURGE:131) and a main memory (1004). The first and second cache memories are operated by the copy-back method. The state of the data of the first cache (100:#1) exists in one state selected from a group consisting of an invalid first state, a valid and non-updated second state and a valid and updated third state. The second cache (100:#2) is constructed like the first cache. When the write access of the first processor hits the first cache, the state of the data of the first cache is shifted from the second state to the third state, and the first cache outputs the address of the write hit and the invalidating sig­nal to the address bus and the invalidating signal line, respectively. When the write access from the first processor misses the first cache, a data of one block is block-transferred from the main memory to the first cache, and the invalidating signal is outputted. After this, the first cache executes the write of the data in the transfer block. In case the first and second caches hold the data in the third state relat­ing to the pertinent address when an address of an access request is fed to the address bus (123), the pertinent cache writes back the pertinent data in the main memory.
