Title: Oblique incident interferometer
Inventor: KANETANI MOTONORI
IPC: G01B11/30
Filed: 1994-03-24
Abstract: PURPOSE:To provide a compact oblique incident interferometer arranging a plane reflector for reflecting the object light perpendicularly to a flat plane to be inspected so that the the object light reenters a reference plane in parallel with the incident light to the plane to be inspected regardless of variation in the incident angle of a coherent light to the plane to be inspected thereby simplifying the structure. CONSTITUTION:A reference plane 26a is a half mirror having high planarity and a part of projected parallel luminous flux 31 passes the half mirror as it is while the remaining parallel luminous flux 31 is reflected as a reference light. The parallel luminous flux 31 is projected onto a plane 27a to be inspected having micro irregularities and reflected regularly thereon as an object light 32. Since the object light 32 is reflected regularly on a plane reflector 28 arranged perpendicularly to the plane 27a to be inspected, the object light 32 reenters the reference plane 26a in parallel with the parallel luminous flux 31. Fringes are formed on the light receiving plane 30 of a CCD through interference of the reference light 33 and the object light 32.

Title: Polarized light selecting element and image display device
Inventor: MIZUGUCHI YOSHIHIRO
IPC: G02B27/28
Filed: 1993-03-15
Abstract: PURPOSE:To provide the polarized light selecting element which is small in size and lightweight and easily obtain linear polarized light in a necessary direction from a white light source for natural polarized light. CONSTITUTION:This polarized light selecting element 3 has plural polarized light separating surfaces 3b whose normals are at 45 deg. to the travel direction of incident light, so 50% of the incident light is transmitted as P-polarized light through the polarized light selecting element 3. Adjacent polarized light separating surfaces 3b cross each other at right angles, so S-polarized light is reflected by a polarized light separating surface 3b on which the light is made incident and then reflected again by a polarized light separating surface 3b on which its reflected light is made incident. Consequently, the S-polarized light is reflected to the light incidence side. Thus, a polarized light component in a necessary direction can be extracted from natural polarized light (unpolarized light).

Title: Lower tie plate with graded opening for controlling pressure drop and flow distribution
Inventor: ERITSUKU BAATEIRU JIYOHANSON
IPC: G21C3/322
Filed: 1990-03-08
Abstract: PURPOSE: To generate an even and uniform coolant flow by supporting a fuel rod in an upright state and introducing a moderator-coolant to the position of the fuel rod supported above a lower tie plate from the bottom of the tie plate. CONSTITUTION: A rectangular corner section 78 exists between a lower opening 72 and an upper opening 76 and the corner section 78 generates the maximum quantity of a predictable turbulence in the flow of a coolant 50. Such a turbulence and the energy diffusion associated with the turbulence increase a pressure drop when the turbulence passes through a lower tie plate and the increased pressure drop results in the distribution of a uniform flow. In other words, when the flow flowing to the position of the tie plate through a nose piece meets a large resistance, the flow is diffused to the outer edge of the tie plate and causes a uniform flow over the entire area below a fuel bundle.
