Abstract: PURPOSE:To easily obtain a large area of low noise and high sensitivity, by clamping a light absorbing layer having forbidden bandwidth of Eg1 and a step-back structure between electron injection blocking layers, in which structure a forbidden bandwidth continuously changes between the minimum forbidden bandwidth Eg2 and the maximum forbidden bandwidth Eg3. CONSTITUTION:A light absorbing layer 310 which has a forbidden bandwidth Eg1 and absorbs light and a plurality of step-back structure layers 301, 303, 305, 307, 309 are sandwiched between a P-type semiconductor layer 311 and an N-type semiconductor layer 315 which turn to electron injection blocking layers. In the step-back structure layer, a forbidden bandwidth which multiplies carriers generated by absorbing light continuously changes between the minimum forbidden bandwidth Eg2 and the maximum forbidden bandwidth Eg3. The P-type semiconductor layer 311 and an electrode 313, and the N-type semiconductor layer 315 and an electrode 314 are electrically connected and formed on a glass substrate 316. Thereby a large area which is excellent in high speed response and has low noise properties and high sensitivity for visible light can be easily obtained.

Title: Controlling method for number of pump
Inventor: KURODA YASUYUKI
IPC: G05B11/18
Filed: 1979-04-25
Abstract: PURPOSE: To enable an online computer to exercise economical control over the number of pumps  by predicting the number of pumps while the cumulated value of the inflow of the arrived water  well of an intake plant will be between the upper and lower limits of the predicted cumulated value of outlet water discharge all the time, and then by finding the number of pumps to be put into  operation corresponding to a request responding to it and the operation cost.   
     CONSTITUTION: Water from intake pump 1 is stored in arrived water well 2 and sent out at need  and controller 3 for the number of pumps controls the start and stop of each pump. Then, the  predicted discharge of the arrived water well is cumulated in terms of time to obtain curve E and  then the changeable value of the overall water discharge of the arrived water well, i.e., the water  volume at the time of the two-water level upper limit and that at the time of the one-water-level  lower limit are added to curve E to find curve F. Here, while cumulated value A of arrived-water  well intke flow is set between curves E and F all the time, the number of pumps to be put into operation is predicted and the demand and operation cost agreeing with the predicted number of  pumps are used to determine the number of pumps to be put into operation. Consequently, a solution which is not strict but quasioptimum is found by the set of relatively-simple processes, so that  a online control computer will be enabled to exercise control over the number of pumps.

Abstract: PROBLEM TO BE SOLVED: To improve detection ability without causing any increase of processing load or a quantization error in detection processing in a target detector based on line segment detection. SOLUTION: A radar reception signal is detected as binarized data in a threshold detection circuit 1. Detection data of the past M-time scan are held, and coefficient data corresponding to the position in the M-time scan are generated in a coefficient generating circuit 6 at every assumed target speed. In line segment detection computing circuits 4-1 to 4-K, the sum of products of the past M-time scan detection data and the coefficient data is computed, and the data is detected at every speed by line segment detection. A Doppler frequency is detected from the radar reception signal, and a speed is calculated from the Doppler frequency.  A speed corresponding to an addition result selected from the maximum value and a moving speed calculated from the Doppler frequency are compared with each other, and when the comparison difference is a set allowable error value or less, it is determined as a target and target data are outputted.
