CONSTITUTION:An l-type layer 42 and a P-type layer 44 are formed on an N-type high- resistance semiconductor substrate 40. Electrodes 46A and 46B are provided at the ends of the structure and an N+type common electrode layer 48 is provided on the bottom face of the substrate. In this manner, K element arrays are produced. The positive pole of a DC power source 50 is connected to the common electrode 48 while the negative pole is connected to the electrodes 46A and 46B via load resistances 52A and 52B. When light is applied to the P-type layer 44, photocurrents I11-I1k and I21-I2k flow through the load resistances 52A and 52B, respectively. An arithmatic logic unit 54 substracts the I2n from the I1n by means of a differential amplifier 56 and sums them by means of a summing amplifier 58, while a comparator 60 compares the summed value with a prdetermined value and outputs only the values larger than the predetermined value as gate output. They are divided by a dividing amplifier 64 and a value of (I1n-I2n)/(I1n+I2n) is outputted. When the output Hn of the comparator 60 is 'H', light is detected by the (n)th element and the position Yn at that moment can be obtained by calculation.

Filed: 1979-08-28
Abstract: PURPOSE: To prevent the slackening and separation of the subject mechanism as  well as to improve the workability and reliability by a method wherein only those  pipes which are in the peripheral portion of a pipe group and applied with larger  axial load, among the assembly of cooling pipes and tube plates of a condenser in a  power generation plant or the like, are fixed by welding and the others are fixed by  pipe expanding method.  
     CONSTITUTION: In the arrangement of cooling pipes of a condernser, the shaded portion (a) is a region where larger tensile loads are applied, so that the tube plates and the cooling pipes in this region are fixed by welding. On the other hand, the pipes in region (b) are fixed only by pipe expanding method, since smaller loads are applied in this region. Accordingly, the welding amount can be reduced largely, the fixing at the portions subjected to larger loads can be made rigid, and the slackening and separation of the tube plates and cooling pipes can be prevented, resulting in improved workability and reliability of the mechanism.
