Title: Matrix-type Optical Concentrator-distributor
IPC: H04Q3/52
Filed: 1982-02-09
Abstract: A matrix-type optical concentrator-distributor comprises a matrix of retractable light deflection members 2, whereof the m lines and k columns (respectively l remaining columns) are optically connected to m and k transmitter-receivers (respectively l transmitters) of light signals to form two submatrixes having respectively kxm and lxm of said members. Preferably, the kxm members permit the passage of the incident signals from the transmitters and in part those from the transmitter- receivers and the lxm members permit the partial passage of the incident signals from the l transmitters and the m transmitter-receivers. This leads to bidirectional communication between the m and k transmitter- receivers and unidirectional communications from the l transmitters to the m transmitter- receivers, optically managed by the means 1, 8 intercepting a transmitted part of the signals. <IMAGE>

Title: Circuit protecting sensor
Inventor: CHUZAWA TAKAAKI
IPC: H01H71/34
Filed: 1982-04-06
Abstract: A circuit protecting sensor (10) comprises a cylinder (12) divided into two cylinder members (13, 14) with a common magnetic head (15) interposed between them. One of the members (13) contains a viscous fluid sealed therein and an oil plunger (16) and the other member (14) contains an operating plunger (19) projecting partly out of the cylinder. The plungers are biased by respective springs (17, 30) normally away from the magnetic head (15). When a short-circuit current is detected by a coil (24) wound on the cylinder (12), the operating plunger (19) is immediately attracted by the magnetic head (15) independently of the oil plunger (16) prior to its attraction to the magnetic head. When a relatively small overcurrent is detected by the coil (24) the operating plunger (19) is not attracted to the head (15) until the oil plunger (16) reaches the head, thereby achieving a time delay. <IMAGE>

Title: Method and apparatus for measuring thermal neutron characteristics
Inventor: JACOBSON LARRY A
IPC: G01V5/10
Filed: 1982-10-08
Abstract: The thermal neutron decay characteristics of an earth formation are measured by detecting indications of the thermal neutron concentration in the formation during measurement intervals G1, G2.... following irradiation of the formation with a burst of fast neutrons. These measurement intervals consist of a sequence of discrete time gates which begins following a predetermined time delay after the preceding neutron burst and is divided into a number of groups, e.g. G1-G4, G5-G8, and so on. The durations of the individual discrete time gates within the groups are equal, but the duration of the time gates progressively increases from group to group in the sequence, e.g. geometrically, preferably doubling in consecutive groups. The groups, and the gates within them, may be contiguous as shown. The durations of the gates may extend from one which is shorter than the neutron burst, to one which is at least as long. The number of groups may equal the number of gates in each group, preferably four. <IMAGE>
