摘要： PURPOSE:To improve noise characteristic significantly, by a method wherein amplifiers are placed close to radiation sensing elements on several substrates separately and the substrates are arranged to be laminated parallel at a wider interval than a pitch of a sensor radially with respect to the sensor. CONSTITUTION:Amplifiers 3 placed close to individual radiation sensing elements are arranged on amplification substrates 5 in the form of an amplifier array 4 formed on one-piece of multiple substrates. In the package structure, the amplification substrates 5 are arranged radially centered on radiation sensors 1. Thus, high-impedance input parts of the amplifiers arranged close to the individual elements permit the increasing of spatial distances between the adjacent amplifiers 2-100 times. This lowers a floating capacity on circuits, thereby reducing mutual interference between the elements and noise significantly.

摘要： PURPOSE:To obtain a semiconductor radiation detector, which presents high detection efficiency without change in sensitivity with time, by providing a tellurium oxide layer between a metal electrode layer and a cadmium telluride crystal to prevent formation of a barrier layer between the cadmium telluride crystal and the metal electrode layer so that good ohmic contact may be formed. CONSTITUTION:A Te layer is deposited on one face of a high-resistance CdTe crystal 1 with a resistivity of 10 -10 OMEGAcm by vacuum evaporation and thermally oxided to form a TeOX layer 2. An Au electrode 3 is formed on the TeOX layer 2 by vacuum evaporation. A TeOX layer 2 and an Au electrode 3 are also laminated on the other face of the CdTe crystal 1 by a similar method, and thus a full depletion layer type CdTe radiation detector is constituted. Since there is no barrier layer on the junction interface between the Au electrode 3 and the TeOX layer 2 and no space charge is accumulated, an extremely stable semiconductor radiation detector is realized which operates for a long time without the change in detection sensitivity.

摘要： PROBLEM TO BE SOLVED: To measure a large acceleration and a small acceleration by one acceleration sensor by measuring each acceleration smaller and larger than a predetermined value using an output of each amplifier circuit for a small acceleration and a large acceleration. SOLUTION: A reference voltage of a comparator of a first signal conversion circuit 4 connected to a first amplifier circuit 2 is imparted by a micro-computer. A signal is outputted when a signal of a voltage higher than the reference voltage is inputted to the comparator. If the reference voltage is set to a voltage corresponding to a degree of the acceleration to be distinguished, it can be easily detected that an acceleration larger than the acceleration set is applied. An output signal of a second amplifier circuit 3 is inputted to a second signal conversion circuit 5 and is A/D converted. The acceleration degree is converted to a digital value and is inputted to a micro-computer of a control circuit 6. In the micro-computer, a command of a corresponding indication is given according to the digital value of the acceleration. Since all acceleration signal wave forms can be taken in the A/D converter, not only the acceleration degree but also a frequency can be measured and a high accurate measurement can be carried out.

摘要： PROBLEM TO BE SOLVED: To obtain a junction wafer which easily discriminates a junction boundary by joining without a sticking layer, and as a result to produce a wafer for a piezo-electric element which does not have so many errors at the time of working and has high manufacturing yield by utilizing the junction wafer and to obtain a high frequency piezo-electric resonator, for instance, by producing a thin, but high precision junction wafer that has a polarized inverted structure. SOLUTION: A 1st single crystal piezo-electric substrate (colored wafer) 2 that is colored and a 2nd single crystal piezo-electric substrate (non-colored wafer) 1 with a different color tone are directly connected, and the surface and rear or the boundary are easily discriminated as a polarized inverted structure junction wafer (junction wafer) 3. Also, by detecting a different color boundary with an optical method, it is possible to measure layer thickness by utilizing laser beams before and after working or during working.
