Title: Seat belt retractor
Inventor: FUJIMURA YOSHIICHI
IPC: B60R22/40
Filed: 1993-01-29
Abstract: A pivotable inertia member (15) of a webbing pull-out speed sensor is set so that when, in an inoperative position, it abuts on a first stopper (14h), the center of gravity (G) of the inertia member (15) lies at a position which is on an extension of an imaginary line ( gamma ) connecting the center of the belt reel shaft (4d) and the center of the pivot shaft (14f) of the inertia member. Moreover, the said position is closer to the shaft (14f) than to shaft (4d). The inertia member is mounted via the shaft (14f) on an actuating member of associated locking gear which responds to excessive vehicle deceleration. Thus when the locking gear rotates as the webbing (3) is unwound or wound up under normal circumstances, centrifugal force acts because the line of action of the centrifugal force lies on the on the center of gravity of the inertia member. However, line ( gamma ), the inertia member is not subjected to a moment about the shaft (14f) by the centrifugal force. Thus inadvertent locking engagement of a pawl (15c) of the inertia member (15) with a tooth (13c) during normal circumstances, is avoided. Many other details of the seat belt retractor are described. <IMAGE>

Title: Soldering silicon
Inventor: FERRANDO CARLO
IPC: B23K35/00
Filed: 1993-03-03
Abstract: A joint for joining a silicon disc (21) to a molybdenum disc (22) comprises a layer of titanium silicide (20) and a layer of aluminium-silicon solder (23). The titanium silicide is formed by depositing a layer of titanium on the silicon disc and heating the silicon disc and the titanium to around 550 DEG C to encourage the formation of titanium silicide. A solder disc is then compressed between the silicon and molybdenum discs at about 690 DEG C to fuse the solder to the titanium silicide layer and the molybdenum disc. The layer of titanium silicide protects the silicon disc from dissolution during soldering, so that diffused-in features in the silicon are not damaged. <IMAGE>

Patent GB-2271178-A (GB)
Title: Nuclear logging apparatus
Inventor: NORDSTROM ROY
IPC: E21B47/01
Filed: 1993-12-03
Abstract: Nuclear logging apparatus in which radiation detectors 74, 76 near and far from a radioactive source are supplied with power via high voltage filter means 168 and output a signal via a preamplifier means 170. The filter means removes high frequency noise from power supplied to the detectors and the preamplifier means adjust the gain of the output signals to within preselected amplitude limits. This gain adjustment assures that the neutron peak occurs in the proper position in the spectra. The outputted signal is supplied via a multiplexer (176, Fig 24, not shown) to a programmable gain amplifier (178) which improves signal to noise ratio and quantifies the pulse amplitudes within predetermined spectral limits. The output from the PGA is received by peak detection means (180) to convert the signal to a stable DC pulse for digitising by an A/D converter (184). The multiplexer acquires data from the detectors over a preselected acquisition cycle which differs for each detector. <IMAGE>
