Title: Cornea shape measuring instrument
Inventor: KAWAI NORIJI
IPC: A61B3/10
Filed: 1993-04-30
Abstract: PURPOSE:To easily derive an imperfect shere's radius of curvature being orthogonal to a principal meridian by allowing a reflected light obtained by projecting light from source of two sets or more provided with an optical axis in the center to transmit through a lens and a telecentric diaphragm, dividing it into two by a beam splitter and detecting it by a one-dimensional detecting element. CONSTITUTION:From one set of light sources 1a, 1b consisting of plural symmetrical light emission diodes set centering around an optical axis consisting of a chain line, the cornea 3 of an eye to be examined is irradiated obliquely with light beams made parallel by lenses 2a, 2b, and point light source images 1a', 1b' are formed. The reflected light from the light source images 1a,' 1b' is allowed to form an image on a telecentric diaphragm 6 by a lens 4. The light beam which passes through the diaphragm 6 is divided into two by a beam splitter 7, allowed to transmit through convex lenses 8a, 8b, and the light beam is detected by one-dimensional detecting elements 5a, 5b at a position being conjugate to the diaphragm 6. Subsequently, the similar measurement is executed by the light source from a direction different from the sources 1a, 1b. In such a way, an imperfect shere's radius of curvature being orthogonal to a principal meridian is derived easily.

Title: Lighting surface protective circuit for subscriber circuit
Inventor: SATO MASAFUSA
IPC: H02H9/04
Filed: 1995-05-26
Abstract: PURPOSE: To protect a lightning surge protective varistor in a subsrciber circuit against breakdown when a subscriber line touches a commercial power supply by grounding the subscriber line through a varistor and connecting a capacitive element, which exhibits a low impedance for lightning surge but exhibits a high impedance for a commercial frequency power supply, in series. CONSTITUTION: Upon intrusion of a lightning surge voltage into a subscriber line 11, a varistor 12 is conducted instantaneously and a current flows through a capacitive element 13 to the ground. Since the lightning surge is a steep pulse (high frequency), the capacitive element 13 exhibits a low impedance for the lightning surge and does not impede the ground fault current. When the subscriber line 11 touches a commercial power supply, the varistor 12 is conducted intermittently and a ground fault current. But since the capacitive element 13 exhibits a high impedance for commercial frequency (50 or 60Hz), the varistor 12 limits the current flow.

Abstract: PURPOSE:To improve adhesive properties between a polycrystalline silicon film and an oxide film remarkably, and to inhibit the abnormal diffusion of an impurity by directly oxidizing the polycrystalline silicon film and using the polycrystalline silicon film as a mask for diffusing the impurity. CONSTITUTION:A field oxide film 2, gate electrodes 3 and an inter-layer insulating film 4 are formed to the surface of an silicon substrate, and a polycrystalline silicon film 5 is applied and shaped onto the surface of the film 4. The surface of the polycrystalline silicon film 5 is patterned, and oxidized through heat treatment, and a thermal oxide film 11 is formed. One part is removed, and an impurity 7 is diffused, thus lowering the resistance of a section to which the impurity 7 is diffused, then shaping power supply lines 12. The impurity 7 is not diffused to sections coated with the thermal oxide films 11 because the thermal oxide films function as masks at that time. Accordingly, load resistance sections 13 left under the state of high resistance are formed, and the thermal oxide films 11 are shaped by directly oxidizing the polycrystalline silicon film 5, thus extremely improving adhesive properties.

Title: Operation control of nuclear reactor
Inventor: TAMURA AKIO
IPC: G21C7/08
Filed: 1988-05-27
Abstract: PURPOSE:To keep a load following capability with a rather small number of control rods, by providing both low absorption control rods and high absorption control rods and by selecting one of both kinds of the rods according to a received signal of an averaged temperature deviation of a nuclear reactor coolant with a consideration of a deviation signal of an axial output distribution. CONSTITUTION:By this particular method, a low absorption control rod GR is selected by a deviation signal from a standard value of an averaged temperature of a primary coolant, otherwise, a high absorption control rod D is selected according to a deviation DELTAI of an axial output distribution shown as an equation I. In case that a deviation from a standard value of an averaged primary coolant temperature, that is, a temperature deviation DELTAT, is negative, which means a case of a withdrawal demand, the deviation DELTAI of an axial output distribution moves towards a positive side. With this reason, in case that the DELTAI is more negative than a certain value compared to a control target, the high absorption control rod D is selected and otherwise the low absorption control rod GR is selected, alternatively. With this sort of procedure, the reactor can be controlled, neglecting a meaningless movement of control rods and a mutual interfere of both kinds of the control rods.
