Title: Optical temperature measuring instrument
Inventor: HISHIKARI ISAO
IPC: G01K11/12
Filed: 1987-03-23
Abstract: PURPOSE:To measure temperature with high sensitivity by projecting and photodetecting light on an interference film filter as a temperature sensing part through an optical fiber, detecting light by detectors as to two wavelengths from the optical fiber, and measuring the temperature from the ratio of both outputs. CONSTITUTION:Light from a light source 1 is projected on the interference film filter 3 as the temperature sensing part by the optical fiber 2 through a half-mirror 71. Light reflected by the filter 3 is passed through the optical fiber 2 again and reflected by the mirror 71. Light from the mirror 71 which is branched by a half-mirror 72 is transmitted through filters 41 and 42 and incident on detectors 51 and 52. The outputs of the detectors 51 and 52 are supplied to a measuring means 6, which performs proportion arithmetic to measure the temperature. Namely, the filter 3 shifts in reflection wavelength characteristics to the long-wavelength side from A to A' as the temperature T rises. Further, the transmission wavelength characteristics of the filters 41 and 42 vary in the degree of the overlap between depression parts A and A' of the transmission wavelength of the filter 3 as to one B and the other C does not varies. For the purpose, the ratio of the detectors 51 and 52 is calculated to remove a measurement error due to a change in the state of the optical path, etc., so that the temperature is measured with high accuracy.

Title: Production of cubic boron nitride film
IPC: C23C28/04
Filed: 1992-03-26
Abstract: PURPOSE:To prevent a film from being peeled off when the film is formed by successively forming a titanium nitride film and a silicon nitride film on an iron-based base material and then forming a cubic boron nitride(cBN) film by ion plating. CONSTITUTION:When a cBN film is formed on an iron-based base material 19 by ion plating, a titanium nitride film and a silicon nitride film are successively formed as the intermediate layers by ion plating. The titanium nitride film has an excellent affinity for the base material, the silicon nitride film has the excellent affinity for the cBN film, and the titanium nitride film has the good affinity for the silicon nitride film. The order of the thermal expansion coefficient of each film is found to be silicon nitride < cBN < substrate 19, and hence the compressive stress is relieved by using the silicon nitride film as the intermediate layer directly below the cBN film. Consequently, the cBN film is excellently formed on the silicon nitride film as the intermediate layer.

Abstract: PURPOSE: To lessen the load on a control firmware by forming only the data of echoes in this control firmware and reading out the data of an image memory written in the past as trail data. CONSTITUTION: The control firmware 2 generates only the echoes obtd. by one time of scanning of a radar antenna in one period of 0 deg. direction synchronizing pulse. A writing selection circuit 3 selects the image memory to write the output of the control firmware 2.

This luminance conversion table 6 is so connected as to impart most frequent attenuations to the oldest data by changeover by the 0 deg. direction synchronization from a timing signal generating circuit 1. The data of the image memory written in the past is read out as the trail data in such a manner.

Filed: 1986-03-27
Abstract: PURPOSE:To attain the stable drive of an inductive load by keeping the current ratio of an output circuit of current mirror coupling constant and providing a series connection transistors (TRs) to reduce an output static capacitance. CONSTITUTION:A base of a TR Q3 is connected to a collector and also to bases of n-set of TRs Q41-Q4n, they are in current mirror coupling. The base of a TR Q5 is connected to a constant voltage Vl, the emitter is connected to a common collector of TRs Q4l-Q4n, the emitters of the TRs Q41-Q4n are connected to resistors R4l-R4n whose other ends are connected to ground independently. Since the common collector of the TRs Q41-Q4n is connected to the emitter of the TR Q5, a current being n-times of the current I11 of the TR Q5 flows and the same current flows to the collector of the TR Q5. Since the static capacitance viewed externally is the combination of the capacitance of the TR Q5 and that of the TRs Q41-Q4n, that is, a capacitance below the substantial capacitance of the TR Q5, the size of the TR Q5 is decreased, then the static capacitance to the load is reduced.

Title: Oxidizing method for semiconductor device
Inventor: NAITOU MASAMI
IPC: H01L21/316
Filed: 1984-04-09
Abstract: PURPOSE:To easily obtain an oxide film of prescribed thickness under all processing conditions by a method wherein an oxide film is formed under the condition which is different from the processing condition of a model by spending the oxidizing time for the target film thickness, and the oxidizing time is corrected based on the obtained film thickness. CONSTITUTION:The curved line 1 in the diagram shows the relations between the oxidizing time (t) to be used as a standard and the oxide film thickness (Z) in a double logarithmic graph. Under normal condition, the oxiding time required to obtain the target value Z0 of the film thickness is t0, but when the film thickness for the oxidizing time t0 is actually measured as Zm, a new Z-t reaction is changed to the curved line 2. Accordingly, under the processing conditions changed as above-mentioned, the target film thickness is to be set at the oxidizing time t1 for Z0. When the film thickness is actually measured as Zn, the oxidizing time becomes t2 by having the Z-t relation as shown by the curved line 3. When the thickness of oxide film Z and the oxidizing time (t) are shown by logarithm, the growth of oxide film is shown by an approximate straight line. Also, in such a case where the primary factors of processing and the like are changed, the film growing graph can be shown by performing an approximate parallel movement in a double logarithmic graph.
