Title: Absolute-position detecting apparatus
Inventor: OKA YASUO
IPC: G01D5/36
Filed: 1991-01-11
Abstract: PURPOSE:To make it possible to perform highly accurate position detection by reducing the fluctuation of the absolute position data obtained by additive averaging. CONSTITUTION:Quantized values q  and q  which have entered into a quantizing range from the upper limit side and the lower limit side are used, and absolute position data Z  and Z  are obtained, respectively. The additive averaged value (Z +Z )/2 is made to be the absolute position data ZA. The widths of a stripe pattern (a) and a matrix pattern (b) are set so that photodetectors PE wherein the quantized values q  and q  are obtained are separated by one picture element in the vertical direction and located at the same position in the horizontal direction. Since both picture elements are close, the characteristics of both picture elements become approximately equal. The difference in fluctuation of sensitivity due to temperature fluctuation becomes small. Thus, the difference in amounts of fluctuation of Z  and Z  in the reverse direction to each other is eliminated. The absolute position data ZA become the stabilized values, and the highly accurate position detection can be performed.

Title: Fuel element
Inventor: KOIZUMI SHIGEMI
IPC: G21C3/16
Filed: 1978-01-17
Abstract: PURPOSE: To reduce fuel damage rate by increasing the He gas pressure in a fuel element.  
     CONSTITUTION: The Hi conventionally sealed at atmospheric pressure is enclosed in a fuel element at a pressure of 1.5kg/cm 2 a to 3.5kg/cm 2  a (at 20°C). The temperature distribution in the fuel element is shown in the figure. When combustion  advances, the fussion products (Xe, Kr, etc.) of which thermal conductivity is smaller by one digit than that of the He to fill the gap between the pellet and coated  pipe increases and remarkably decreases thermal conductivity. Accordingly, pellet  temperature increases. On the contrary, when the He sealing pressure increases like  this invention, the bad effect of fussion products can be reduced. This is because  thermal conductivity is controlled by He the molar fraction of He and the fussion  products. As a result, the higher the initial he pressure is, the less the F. D. effect  is. The pellet temperature can be kept low and stress corrosion crack be prevented.

Title: Controlling method of inner stress of film
Inventor: KURATANI NAOTO
IPC: C23C14/54
Filed: 1994-01-17
Abstract: PURPOSE:To control the inner stress generating in a film when various kinds of films are to be formed, by controlling the grain size in the film formed. CONSTITUTION:After a substrate 1 is supported on a holder 2, a vacuum chamber 7 is evacuated in a specific vacuum degree. Vaporized material 3a from a vapor source 3 is vacuum deposited on the substrate 1. Simultaneously, alternately, or after the vacuum deposition, the vapor deposited surface is irradiated with ions 4a from an ion source 4. The size of grains which constitute the film and the inner stress correlate with each other, so that the compressive stress increases as the grain size becomes larger. With the smaller grain size, the higher tensile stress is obtd. The grain size of the film varies depending on the energy of ion radiation. With the larger energy of ion radiation, the smaller grain size is obtd, while with the smaller energy of ion radiation, the larger grain size is obtd. Thereby, the accelerating energy of ion irradiation is controlled to form the film having a grain size to give a desired inner stress.
