Abstract: PURPOSE:To decrease measuring errors which are larger than the true value of pressure when ambient temperature rises up in a piezoelectric type pressure sensor. CONSTITUTION:One edge of a piezoelectric element 14 is fixed to a frame 11 with an upper fixing screw 15. One edge of a pressure transfer member 13 is in contact with a pressure receiving surface 12, and the other edge is in contact with the other edge of the piezoelectric element 14. The pressure transfer member 14 transfers pressure which is applied on the pressure receiving surface 12 to the piezoelectric element 14. One edge of a temperature compensating spacer 16 made of a material, whose thermal expansion coefficient is larger than that of the frame 11, is fixed to the frame 11 with an overhang 17, and the other edge is in contact with the pressure receiving surface 12. The pressure which is applied on the pressure receiving surface by the increase in ambient temperature is pushed back by thermal expansion. Thus, temperature compensation is performed.

Abstract: PURPOSE:To make it possible to perform high temperature annealing and to improve an activating rate, by forming an AlAs layer characterized by excellent heat resistance on the surface of a GaAs substrate, and performing activating annealing with said layer as a protecting layer. CONSTITUTION:On the surface of a GaAs substrate 1, an AlAs layer 10 and a GaAs layer 11a are deposited and formed. After a specified resist pattern 12 is formed, impurity ions are implanted. After the resist pattern 12 is removed, activating annealing is performed, and an n-type semiconductor region 2a is formed. Since the AlAS layer characterized by excellent heat resistance is used as a protecting film, said anneal ing can be carried out at a high temperature. Therefore, the sufficient activation can be performed without imparting stress to the GaAs substrate 1. Thereafter, the GaAs layer 11, which is sublimated by said annealing, is formed again. Then, a gate electrode 5, a channel region 2, a source reion 3, a drain region 4 and the like are sequentially formed.

Filed: 1981-09-04
Abstract: PURPOSE:To evaluate the quality of a photo-electric sensor by timely measuring the amount of electric current related to the output change of the photo-electric conversion element. CONSTITUTION:Closing a checking switch 12, the variable resistor 17 of a measuring instrument 15 is adjusted to control the amount of electric current to be supplied to a test light source 3. Specifically, with the illumination of the light source increased, a detection circuit 8 reads out the D.C. current value when a common terminal COM and a normally open terminal NO are short-circuited, marking the intersection between the days elapsed and the D.C. current value with a circle. Then, reducing the illumination of the test light source 3, the D.C. current value is read out when the circuit connecting the terminals COM and NO is closed, marking the intersection with the days elapsed with a cross. Like measurement of D.C. current is carried out on the 10th day counting from tis marking, again marking the intersections with the days elapsed with a circle and a cross. By tying the circles and crosses timely change of the photo-electric sensor is estimated enabling evaluation if the sensor properly works or not.

Abstract: PROBLEM TO BE SOLVED: To achieve a more detailed and handy evaluation of an interactive force between particles in a suspension by a method wherein a sample is rotated for a fixed time length to make the particles centrifugally settle and a relationship is determined between the number of revolutions of a centrifugal machine and a filling rate. SOLUTION: When evaluating, for example, a difference in interactive force between particles due to a difference in the pH of the slurry of ceramic particles, easy-to-sinter alumina is used as a material powder. Nitric acid is used as a dispersant to be set by the mol. concentration. Then, firstly, after the adjustment of the slurry, the slurry is made to centrifugally settle using a centrifugal machine. In the measurement of the height 6 of a cake layer 7 after the centrifugal settlement, a test tube 2 having the slurry centrifugally settled therein is put upright to measure the height 6 to the interface of the cake layer 7 and the supernatant layer 8 from the bottom part of the test tube. Then, the height of the cake layer measured after the centrifugal settlement is converted to a filling rate to evaluate.  When a difference is noted in the filling rate depending on changes in the number of revolutions, the structural changes of the particles are presumed to affect the filling rate.
