Abstract: Method and device for measuring an electrical alternating quantity with temperature compensation In a sensor element (3), the polarization of polarized measuring light (L) is changed as a function of the alternating quantity (X). After passing through the sensor element (3), the measuring light (2) is split into two differently linearly polarized partial light signals (LS1, LS2), which are converted into electrical intensity signals S1 and S2. An intensity-normalized signal P = (S1-S2)/(S1+S2) is then formed. A temperature-compensated measured signal S = (a*PAC+b*1)/ (c*PDC +d*1) is derived from the alternating signal component PAC and the direct signal component PDC of this intensity-normalized signal P. The temperature sensitivity can thus be reduced by a factor of 10.

Inventor: BOLDUC MAURICE
IPC: E04B2/02
Filed: 1996-04-09
Abstract: Disclosed are two variants of a block for building a retaining wall. In a first variant, the block forms an end block. In another variant, the block forms a corner block. The construction block has a projection approximately centered on its top surface. The construction block also has a groove at each of the opposite ends on its bottom surface, each groove being approximately centered about the longitudinal axis. The construction block further has at least one slot defining an end piece, transverse to the longitudinal axis, on the top surface or the bottom surface, located approximately halfway between the center point and one of the opposite ends. The block may be stacked on two identical blocks having their opposite ends facing each other, with the block resting on half of each of the two identical blocks, so that the groove at one of the opposite ends of the block is located above half of the projection of one of the identical blocks and the groove at the other opposite end is located above half of the projection of the other identical block, thus staggering the blocks. Furthermore, the one slot makes it possible to have the end piece slitted and cut off from the block to be used as an end block for a retaining wall having a straight edge, by having the groove of the end piece located above half of the projection of the block having had its end piece slitted and cut off. The construction corner block has essentially the same features as the construction block with the difference that the construction block has at least one slot defining a corner piece, transverse to the longitudinal axis, on the top surface or the bottom surface and a transverse groove, having an opening on one or the other of the opposite sides on the bottom surface, the transverse groove being located approximately halfway between the center point and the slot. The construction corner block may be stacked on two other corner blocks, or on two construction blocks or on a combination of both, in the same fashion as the construction block or may be used to form a corner by having the corner piece slitted and cut off from the corner block and have the corner block located adjacent another block with their longitudinal axes perpendicular to each other and have the transverse groove of the corner block aligned with one of the grooves of the other block.

Abstract: On printer (20), tape cartridge (4) is detachable relative to mounting unit (5). Mounting unit (5) is covered by cover (22). When cover (22) is closed, its protrusion (51) rotates rotary component (54), and its operating edge (54b) moves moving component (55). When operating edge (54b) moves over the top edge of surface A  of guiding surface (55a) of the moving component, the cover is completely closed. Subsequently, rotary component (54) is guided to surface B, where it is held in a coupled state. In conjunction with moving component (55), head carrier component (59) rotates, and head (6) located at the tip of the head carrier component becomes fixed at the print position. In the condition in which a print position is formed, rotary component (54) is off from protrusion (51) of the cover. Therefore, no load acts from the side of head (6) onto the side of cover (22). When cover-opening button (24) is pushed down, rotary component (54) disengages from surface B of the moving component, thus creating a condition in which the head has been released.
