Title: Manufacture of optical information recording medium
Inventor: KAMEZAKI HISAMITSU
IPC: G11B7/26
Filed: 1988-11-10
Abstract: PURPOSE:To decrease recording/reproducing errors by dropping water soluble polymers whose concentration is adjusted at a specific value on the signal pattern forming surface of a substrate, rotating it at a specific revolution, eliminating the residual polymers, and forming a indissoluble film for an organic solvent. CONSTITUTION:The concentration of the water soluble polymers is adjusted at 0.5-5.0wt.%, and they are dropped on the signal pattern forming surface of a substrate 1. Next, the substrate 1 is rotated at 300-5,000rpm, and the residual water soluble polymers on the substrate 1 are shaken off and eliminated. Thus, an even dissoluble film 2 having the mean film width 0.035-0.15mum and at the ratio of the maximum film width and the minimum film width <=1.1 can be formed. Next, an organic pigment base recording film 3 is formed on it. Consequently, since a dissoluble processing is executed for the substrate 1 with respect to the organic solvent, the organic pigment base medium causing small tracking errors and recording/reproducing errors can be obtained.

Title: Scanning angle offsetting compensation circuit for scanning-type infrared image pickup device
Inventor: NAKAZATO HIDEAKI
IPC: H04N5/33
Filed: 1990-10-20
Abstract: PURPOSE:To attain the high performance and the miniturization of a device by symmetrically keeping the straight line part of a scanning waveform back and forth as against a scanning center, setting an image pickup period to all the scanning waveform straight line part and maximizing a scanning efficiency rate. CONSTITUTION:A period from rising to falling in the output signal of a photointerrupter 20 increases and decreases in accordance with the offsetting of an angle detector. Thus, the width of the output signal of the photointerrupter 20 increases and decreases in accordance with offsetting. That is, the width of the output signal of the photointerrupter 20 is corresponds to the value of offsetting. The offsetting of an angle sensor 12 is automatically corrected and there is no deviation of an actual scanning angle as against a command signal by correcting a command angle signal with a value obtained by subtracting a reference value from the output signal of the photointerrupter 10 and integrating it as an error voltage. Thus, the all range where the straight linearity of the scanning angle is kept is set as an efficient scanning angle. That is, all the image pickup period is set to all the scanning wave form straight line part.

Title: Method for analysing chemical state
Inventor: IIHARA JUNJI
IPC: G01N23/223
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To detect a chemical state of an element on a surface more deeply even in the atmosphere by irradiating a sample with X-rays high in energy to excite inner-shell electrons and transiting outer-shell electrons to generate holes to use characteristic X-rays generated corresponding to a level difference as a probe detecting the chemical state of the sample. SOLUTION: The effect of a change of a chemical state on characteristic X-rays becomes large by the transition of electrons participated in a chemical bond. In the case of Ga and As, bonded electrons become 4p electrons. A 4p electron orbit is N2.3 and the lagest intensity change is observed in K-N2.3 (Kβ2 ) rays. The electron transition of an outer-shell orbit is set to Σ12 to employ K-N2.3 . Since levels of N are contracted and overlapped, the area of the peak formed by both levels is measured to be set to intensity. This intensity is set to a numerator and characteristic X-ray intensity Σ34 is set to a denominator. An intensity ratio becomes an order of 10<-2> because the peak of Kα rays is high. Detection can be performed in the vicinity of a surface and in several ten layers.
