Title: Making of thin film sample
Inventor: SAKAI AKIRA
IPC: G01N1/32
Filed: 1989-02-13
Abstract: PURPOSE:To enable the observing of a defect part specifically by performing an ion grinding after a ground mark is applied on a grinding surface of a sample containing a lattice defect to be thinned down by a lattice defect selection chemical grinding. CONSTITUTION:Fig. (a) is a sectional view of a sample produced by thinning down silicon containing a grain boundary inside by a mechanical grinding and the grain boundary can be observed from a grinding surface 12 of the sample. In a chemical grinding of the sample, the grain boundary is ground selectively and a ground mark 13 is put on the surface of the sample. The ground mark normally presents a recess in shape with respect to a surrounding surface. When a thin piece with such a shape is set on a single-pore film 14 to perform an ion grinding, a grinding speed is higher at a recess part as compared with the perimeter thereof to finish a part containing the grain boundary the thinnest. This enables the part of the grain boundary to be thinned down locally, thereby observing the part specifically.

Title: Infrared analyzing apparatus
Inventor: NISHISAKA HISAKAZU
IPC: G01N21/552
Filed: 1982-03-05
Abstract: PURPOSE:To perform directly an infrared analysis of a sample in a vessel, by sealing up a window opened to the wall face of the vessel by an infrared rays transmitting plate-like crystal body. CONSTITUTION:Infrared rays L emitted from an infrared spectrometer 9 are made incident to a tip face 7 of a plate-like crystal body 3 at a right angle. Hereafter, said rays L are advanced in a direction of a tip face 8 facing each other by repeating reflection between the upper and lower faces of the crystal body as shown in the figure and are emitted from the face 8. The emitted rays are introduced to the infrared spectrometer 9 to be subjected to the infrared analysis after reflected by a mirror 10. In this manner, the rays L which advance in the plate-like crystal by repeating reflection are absorbed by a sample at the time of reflecting such a face where one side face of the plate-like crystal body is brought into contact with the sample in the vessel directly. The absorption quantity of the infrared rays is varied by the composition of the sample and accordingly, an infrared absorption spectrum in accordance with the composition of the sample is obtained by analyzing infrared rays L' in the spectrometer 9.

Title: Measurement of specific resistance
Inventor: KURODA KUNISHIGE
IPC: G01R27/02
Filed: 1982-03-08
Abstract: PURPOSE:To improve the measuring accuracy with a reduced measuring time by determining a specific resistance from an attenuation time constant of an eddy current in a sample with a sharp change in the external magnetic field after the sample is inserted into one of the two coils arranged in coils for applying the external magnetic field. CONSTITUTION:Pickup coils 6 and 7 are arranged inside a coil 5 for applying a varying magnetic field and connected in series together. A lead wire 6a is connected to a lead wire 7b in the same direction of winding through a variable resistor 8 and lead wires 7a and 6b are connected directly. Terminals 9a and 9b are formed at the connection between the mid point of the resistor 8 and the lead wires 7a and 6b and a bridge circuit is formed so as to take and output from the terminals. Here, after a sample 2 is inserted into one coil 6, the coil 6 for applying the varying magnetic field is excited and cutoff. This enables a voltage signal to be drawn from terminals 9a and 9b only due to the damping of an addy current generated in the sample 2. As long as the time constant in the damping of the eddy current is observed, a specfic resistance is measured which is intrinsic to the material forming the sample 2.

Abstract: PROBLEM TO BE SOLVED: To accurately execute an automatic warning by obtaining one or more of a failure occurrence frequency at each nearly fixed period, a failure occurrence frequency after resetting, at the time of executing the operation of removing a JAM occurrence factor and the transition tendency of the failure occurrence frequency in the past, as a warning condition. SOLUTION: A host computer H obtains the average value of several latest periodical failure occurrence frequencies or a value obtained in such a manner that the failure occurrence frequency after resetting and a periodical failure occurrence frequency are expressed as a point and the points of them are multiplied, as a warning decision factor, to prevent an error of judgment caused by the transient increase of the failure occurrence frequency. Further, when there is a tendency for the transition tendency of the failure occurrence frequency to surely drop, that a warning is not issued is decided, so that even if the failure occurrence frequency at each nearly fixed period or a failure occurrence frequency value after resetting exceeds a reference value, regardless of the fact that the failure occurrence frequency is reduced, the warning is not issued.

Filed: 1979-03-27
Abstract: PURPOSE:To obtain tracking information with one pilot signal track by providing one pilot signal information track in the video disc and by constituting this track so that adjacent parts in the recording position may have phases different from each other. CONSTITUTION:One pilot signal information track TR2 is provided along television signal information track TR1 on video disc 11, and track TR2 is so set that parts interposing track TR1 may have phases different from each other. That is, pilot signal frequency f is set to an odd multiple of the half of the rotation frequency of the video disc for the purpose of obtaining the relation above. The pit detection section duty for one cycle is set to 50% or less. Thus, in case that tracking conditions are changed, tracking information can be obtained even for only one pilot signal track because the pilot signal becomes a low-level signal mode at every other period.
