Abstract: CLASPING DEVICE          Abstract of the Disclosure A clasping device comprises a body and a manipulat-able lever device pivotally connected to the body.  The body has at least two connecting members extending between a pair of side plate members.  One of the connecting members can contact a strap connected to the lever device during normal use to hold the lever device firmly in a locked position.  The other of the connecting members can contact the strap, if the assembly is turned upside down, to hold the lever device in the locked position.  A large part of the lever device is housed between the side plate members of the body substantially parallel to the body in the locked position, whereby the de-vice is easy to handle, firm and resistant to large loads.

Abstract: SIGNAL DETECTING CIRCUIT ABSTRACT OF THE DISCLOSURE          A signal detecting circuit detects the presence in an input signal of a component of a predetermined frequency fp. The circuit includes a sampling arrangement for sampling the input signal at predetermined times separated by a sampling period l/fs and providing first, second, and third signal samples.  An adding circuit provides a sum signal A+C from the first and third signal samples, and a calculating circuit provides a calculated signal 2Bcos.THETA. from the second signal sample, where e is the phase relation of the signal samples 2.pi. fs/fp.  A comparator provides an output signal when the values of the sum signal A+B and the calculated signal 2Bcos.THETA. are substantially equal, indicating the presence of the component of interest.

Abstract: ABSTRACT A FINNED TUBE FOR A HEAT EXCHANGER      A finned tube for a heat exchanger has an inner surface in which is provided raised portions which are in rows and extend in the longitudinal direction of the tube.  The raised portions are arranged, within each row, at irregular intervals and each raised portion may either increase or decrease toward a radially inward tip.  The raised portions may have a cross-section which is substantially triangular or trapezoidal or in the shape of a parallel.ogram and the lateral surfaces of the raised portions, together with the internal surfaces of the tube are roughened during drawing.     In a process of making such a tube, an unhardened tube having a plurality of circumferentially disposed longitudinally extending fins is drawn through a die so as to subject the tube to a cross-sec-tional decrease of at least 50% to thereby fragment the fins to provide gaps between remaining raised portions of the fins.     A drawing die for use in the process has an entry angle .alpha. ? 40°.

Abstract: INPUT PROTECTION CIRCUITS FOR INTEGRATED CIRCUIT DEVICES           ABSTRACT OF THE DISCLOSURE                An input of a CMOS integrated circuit device is protected from excessive voltage swings at an input terminal by a protection circuit which comprises two series-connected protective stages between the input terminal and the device input.  Each protective stage comprises a current-limiting series resistor and clamping diodes connected to the supply voltages of the device.  The two stages enable the series resistance of the protection circuit to be much lower than that required for a single stage diode clamping arrangement, this being particularly advantageous if the device is an analog-to-digital converter for converting to digital values analog voltages present at the input terminal.

Abstract: ABSTRACT     A method for sterilizing packaging material, the packag-ing material being employed subsequent to its sterilization for the aseptic packaging of foodstuffs.  The method includes the steps of (1) first subjecting the packaging material to ultra-sonic vibrations through a liquid medium, and (2) then subjecting the packaging material to ultraviolet radiation.  The bacterici-dal effect of steps (1) and (2) combined together as a sequence in the order recited is greater than if practiced in the reverse order.  The process of this invention can be applied to a moving web of packaging material.  The moving web, after its steriliza-tion treatment, can be fed through known machinery for forming, filling, and sealing of aseptic packages for foodstuffs.

Abstract: Abstract An information processor comprises a plurality of instruction execution units and a circuit that distributes the decoded information of a succeeding instruction to one of the instruction execution units on the basis of sequentially decoded information of succeeding instructions and the decoded information of preceding instructions under the control of the instruction execution units.  Specifically, the distribution circuit distributes the decoded information of the succeeding instruction conflicting with the preceding instruction to the instruction execution unit that is controlling the preceding instruction.  The respective instruction execution units can thus execute the instructions independently of one another while guaranteeing a correctly operated result.  The result is enhancement of the processing capability.
