Title: Method for appreciation of refractive index difference
Inventor: OIZUMI TAKUYA
IPC: H01S5/00
Filed: 1990-05-18
Abstract: PURPOSE:To appreciate readily and surely whether or not a desired refractive index difference is produced in an active layer by determining refractive index difference between an active layer and an impurity diffusion region on the basis of an impurity concentration in a known active layer and an impurity concentration in an impurity diffusion region which is found in advance. CONSTITUTION:Laser light is projected selectively to an action layer 2 part as it is and a P-type impurity diffusion region 4. PL wavelength is measured separately, and impurity concentration in a P-type impurity diffusion region 4 is obtained from the result. That is, since hole concentration po and PL wavelength are in positive correlation, hole concentration po can be known when the difference lambdaPL of PL wavelength values of the active layer 2 and the P-type impurity diffusion region 4 is obtained. Furthermore, since impurity concentration is known, the refractive index difference  n between the P-type impurity diffusion region 4 and the active layer 2 can be obtained only by determining hole concentration po. Thereby, it is possible to appreciate readily and surely whether or not refraction factor difference is a proper value.

Abstract: PURPOSE:To lower friction coefft. and to enhance durability, by using a magnetic coating film contg. as binder components a specified polyurethane resin and an OH-contg. cellulosic resin in a specified proportion, and further polyisocyanate. CONSTITUTION:The binder components of the magnetic coating film contains a polyurethane resin having >=170kg/cm<2> 100% modulus and a hydroxyl group- contg. cellulosic resin in 90:10-70:30 ratio and further, 20-80pts.wt. isocyanate for accelerating cross-linking reaction per 100pts.wt. binder.

Abstract: PURPOSE:To reduce the capacitance variation caused by printing position deviation of electrodes by providing a gap wherein electrodes do not generate overlap on both end edge sides in the width direction, when the direction where end- portion electrodes are formed is set as the length direction and the direction perpendicular to the length direction is set as the width direction. CONSTITUTION:A plurality of layer electrodes 201-208 face each other via dielectric porcelain layers 101-107. The direction where end-portion electrodes 3, 4 are formed is set as the length direction, and the direction perpendicular to the length direction is set as the width direction. Odd number electrodes 201, 203,... and even number electrodes 202, 204,... are so laminated that each position is shifted in the width direction so as to keep gaps G1 and G2 for preventing the overlap of end edge sides in the width direction. Since the width W1 of the electrodes 201-208 are effectively equal, the gaps G1 and G2 become nearly equal. Thereby the overlapping area of the electrodes 201-208 and the electrostatic capacitance can be easily and precisely adjusted.
