Patent JP-H07322549-A (JP)
Title: Liquid pressure source
Inventor: HASEGAWA KISAKU
IPC: H02K5/12
Filed: 1992-05-07
Abstract: PURPOSE:To reduce the turbidity of liquid in a tank and the mixing of foreign matters from a pump into a supply liquid by passing the liquid smoothly through a cooling hole made through the casing of a submersible motor thereby preventing the turbulence. CONSTITUTION:A motor 4 coupled directly with a pump 3 is immersed into the liquid in a tank 2. A liquid suction port, i.e., an opening 21, in the bracket 6 for passing the liquid to the interior of a motor is made only in the vicinity of the bearing housings 6a, 6b of the bracket 6 and not made in the peripheral part. Since a smooth and slow flow of fluid is ensured without causing any turbulence, sufficient cooling effect can be achieved with the liquid flowing through the interior of the motor while preventing the liquid in the tank from becoming turbid or a foreign matter from being mixed over an allowable range into the liquid being fed to the outside through the pump.

Title: Input-output system
Inventor: NARITA TOKIO
IPC: G06F3/00
Filed: 1979-09-04
Abstract: PURPOSE: To make it possible to continue processing as much as possible by collecting state information on an input-output control mechanism in an operation incomplete state.  
     CONSTITUTION: The system controller, when a time supervisory timer detects an input-output control mechanism in an incomplete state, generates the reset instruction. As a result, input-output control mechanism 2-i sends a reset RST signal of "1" to set RQ 2 FF9 while resetting FFs 6, 7 and 8 forcibly. However, the contents of the state information memory part remain without being cleared. Once FF9 is set, OR circuit 14 is turned on to generate interruption request RQ as well as at the normal end. When interruption permitting signal ANS is sent back from system controller 1, AND circuit 12 is turned on and ANSFF10 is set. Thus, input-output control mechanism 2-i makes an abnormal end for the system controller.

Title: Method and apparatus for measuring refractive index
Inventor: MINAMI KOJI
IPC: G01N21/41
Filed: 1995-04-15
Abstract: PURPOSE: To measure the refractive index of a substance having unflat surface, e.g. skin, as it is by determining the reflectance of a sample based on the reflective intensity of the micro facet of the sample at a specified azimuth and the shape distribution function. CONSTITUTION: Light is projected to a sample at a different projection angle αand the reflected light for each projection angle α is received at a plurality of different light receiving angles β. The angle θ=(α+β) 12 is then determined along with the reflective intensity R (θ, ϕ) of a microfacet at an azimuth ϕ. Furthermore, shape distribution function G (ϕ) of the microfacet is determined and then a reflectance F (θ) is determined from the intensity R (θ, ϕ) and the function G (ϕ) according to Fresnel's formula. The reflectance F (θ) thus determined is fitted to Fresnel's formula thus determining the reflectance (n) of the sample. With such arrangement, the refractive index can be measured, as it is, even for an unflat sample, e.g. skin.

CONSTITUTION:A cathode 2 is fixed on the surface of a copper tube 5, and a conductive resistor 6 obtained by hydrogen-plasma spraying TiO2, for example, and a dielectric 7 (glass, ceramic and the like) are alternately fixed to the surface of the copper tube 5. When a laser beam is going to be oscillated, a DC high tension voltage power source 3 and an AC high tension power source 4 are operated, and power is applied between an anode 1 and a cathode 2. As a result, a DC glow discharge 12 is formed between the conductive resistor 6 and the anode 1, and an AC glow discharge 13 is formed between the dielectric 7 and the anode 1. As the ionization of the laser medium located in the vicinity of the conductive resistor 6 is accelerated by the AC glow discharge 13, the concentration of the glow on the surface of the conductive resistor 6 can be prevented, thereby enabling to accomplish a stabilized DC glow discharge even when the pressure of the laser medium is increased.

Abstract: PURPOSE: To enable stable operating by keeping the resonant state of a non- linear Fabry-Perot interferometer in the hysteresis relationship of 'optic/optic' characteristics of the interferometer. CONSTITUTION: Two elements p<+> -ν-n<+> , for which the n<+> area of one element and the p<+> area of the other element are defined as transparent electrodes, are connected to two power sources ε1 and ε2 while inverting polarities and an intermediate point electrically connecting a p<+> area 7 of one element and an n<+> area 6 of the other element is connected through a resistor R to the power sources ε1 and ε2 .
