Title: Temperature distribution measuring instrument
Inventor: WAKAMI TOSHINORI
IPC: G01K3/00
Filed: 1992-06-08
Abstract: PURPOSE:To obtain a temperature distribution measuring instrument having high measurement accuracy. CONSTITUTION:Exciting light from a pulsed light source 14 is split into two parts having equal power through a coupler 12 and the split parts are respectively supplied to fibers 18 and 28 extended in parallel in an area to be measured for temperature. When the intensity ratio between Stokes light and anti-Stokes light returning from the fibers 18 and 28 is found at every time-domain as a signal intensity ratio from which the background component is eliminated, the temperature distribution in the area to be measured for temperature can be found. Since not only the Raman back scattered light returning from the fiber 18 but also the Raman scattered light returning from the fiber 28 can be measured, a sufficient light quantity can be secured for the detection of a detector 16 and the temperature measurement accuracy of this temperature distribution measuring instrument can be improved.

Title: Semiconductor gas sensor
Inventor: SUZUKI TOSHIHARU
IPC: G01N27/414
Filed: 1977-12-08
Abstract: PURPOSE: To obtain small-sized, high-reliability sensor at low cost, by using dielectric film having high dielectric constant between the gate and substrate of a gas sensor using MOS transistor.  
     CONSTITUTION: Various oxides having dielectric constant of at least 10 times are provided between silicon substrate 1 and gate to compose the gate construction. For instance, titanium oxide and magnesium oxide of 18 to 25 and titanium oxide film of 70 to 85 are used as the gate oxide film 4. Therefore, in the presence of hydrogen gas, when hydrogen enters a palladium electrode 5, a polarization layer is formed on the gate oxide film boundary surface, and the work function between the palladium and silicon substrate varies, which causes the threshold value to be deviated. Thus, the change in the threshold value may be detected. In this way, a gas sensor having extemely excellent gas detecting sensitivity and response may be obtained.

IPC: G01B9/02
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to adapt the use of an optical fiber beam to a remote measurement with a high sensitivity and under a high temperature environment by measuring a change in a physical value given to the sensor part by a change in an interference state of the light reciprocating propagating in the optical fiber.

An optical fiber 3 guides the emitted light and reflected light. The sensor part 4 generates reflected returning light having two light paths to an incident light to the optical fiber 3, and returns them to the optical fiber 3. A detection means 5 receives the reflected returning light having two light paths and returning in the optical fiber 3, and detects optical interference which is propagated in the optical fiber 3. Thus, a change in a physical value applied to the sensor part 4 is measured by means of a change in the interference state.

Abstract: A process for growing plants by means of water culture or hydroponics and apparatus therefor are disclosed. The process is particularly well suited for growing relatively bulky plants and includes floating the plants on a nutrient solution by rafts or the like. The rafts are positioned in close proximity to maximize the plant density per unit area of the solution and accordingly the space productivity of the process. As the plants grow on the rafts, the buoyancy of the rafts is increased and the rafts may be laterally displaced proportionally to plant growth to maintain high plant density per unit area of solution. Buoyancy of the rafts is preferably increased by a transrafting step in which a small raft is placed on a larger raft formed to receive the same. In another aspect of the present invention the nutrient solution is used as a transport medium, with the raft supported plants being urged across the nutrient solution as part of plant and/or raft processing steps.
