Abstract: PURPOSE:To enable a semiconductor to be irradiated with light and then taken out with a simple modification of an apparatus by providing a Dewar flask in which two superconducting magnets arranged with a space where a sample semiconductor can be placed and irradiated with light admitted in the Dewar flask along its center axis. CONSTITUTION:A Dewar flask 21 or 22 is provided so that it can permit light to pass through it along its center axis. The Dewar flask includes two superconducting magnets 11A and 11B, in the space between which a semiconductor sample can be placed and irradiated with the light. When the magnets are arranged vertically with their magnetic fields in the same direction, the resultant field is parallel to the center axis in the middle of the space between them. A sample semiconductor is inserted into the middle of the space in the direction of A, and light is admitted in the direction of B. In this arrangement, desired measurements can be carried out; that is, the absorption spectrum of light can be measured. Such a simple modification makes it possible to irradiate a semiconductor with light and take it out.

At this time, a repetitive pulse voltage is applied to an electrode 15 for particle deflection use. When the voltage is not applied to the electrode 15, the voltage is applied to the substrate 12 and when the voltage is not applied to the electrode 15, a pulse voltage is applied to the substrate 12 in a timing of not applying the voltage to the substrate 12.

Filed: 1989-03-20
Abstract: PURPOSE:To accurately measure a strain distribution, etc., in a short time by providing a 1st robot, a 2nd robot, a difference arithmetic means, an expression determining means, a degree determining means, and a distortion arithmetic means. CONSTITUTION:The 1st robot 40 places a load on a body 50 to be measured, the shapes before and after placing a load are measured by the 2nd robot 30, and the difference arithmetic means 61 finds the difference between the shapes before and after the load is placed to obtain discrete displacement data. The expression determining means 62 finds the approximate expression of a displace ment distribution by a spline function from the discrete displacement data. In this case, the degree determining means 63 determines the degree of the spline function by a displacement expression obtained from a model of the body to be measured which is formed by simple load addition. The obtained approximate expression is differentiated twice to find the distortion distribution by the distortion arithmetic means 64 from found curvature. The displacement distribution can accurately be approximated by the approximate expression, so not so many measurement points are required. The measurement time is therefore shortened and the curvature is accurately calculated.

Abstract: PURPOSE:To realize not only a stabilized operation even in a heavy load but a self- starting in case when a battery is applied, by driving both the normal and heavy through a voltage reducing circuit and a constant voltage circuit, respectively, and increasing the level of constant voltage when the clock stops. CONSTITUTION:The on-off of n transistors 26 and 27 of a voltage reducing circuit 10 as well as p transistors 35 and 36 is controlled via a power source control circuit 9. Then capacitors 12 and 13 having the same capacity are connected in series to a power source circuit to reduce the battery voltage down to 1/2, etc. Thus the normal load of an elapsed time circuit or the like is driven. On the other hand, the outputs of AND gates 67 and 68 of the circuit 9 are set at a low level during a heavy load, and thus the capacitors 12 and 13 of the circuit 10 are connected in parallel to be backed up for a prescribed time. After this, a heavy load of a lamp or the like is driven stably via a constant voltage circuit 8. A gate 47 of the circuit 8 is opened by a clock stoppage detecting circuit 84, and the resistance value varies by a partial pressure resistance 86 or the like to increase the level of output voltage of the circuit 8. As a result, a quartz oscillator starts with no malfunction by a high voltage even in case when a battery is applied. Thus an electronic timepiece executes a self- starting.
