The solid electrolyte film includes a first surface and a second surface opposite side of the first surface. The anode is provided to contact with the first surface in a first surface side. The cathode is provided to be separated from the second surface in a second surface side. The flow path is provided between the second surface and the cathode. Water can flow through the anode. Electrolytic solution can flow through the flow path.

Abstract: A High Electric Field Electrolysis (HEFE) cell is provided for electrolyzing water to transform it into Free Radical Solution (FRS) water for cleaning, deodorizing, and sterilizing. The HEFE cell is comprised of a pair of flat electrodes attached (or coated) onto a flat proton ion exchange membrane enclosed in a corresponding structure that accommodates the electrodes and the proton ion exchange membrane. The structure is comprised of at least one inlet channel for receiving purified water and two outlet channels for output of electrolyzed FRS water and hydrogen rich water. The HEFE cell further provides a mechanism for recycling of hydrogen rich water for re-use or electric power generation. The quantity and the quality of FRS water production is controlled with an external control circuit that automatically monitors and maintains appropriate parameter values for the production of FRS water.

Abstract: Free Radical Solution functional (electrolyzed) water with high oxidation reduction potential of 900 mV, and with a stable Hydrogen Ion Concentration (HIC) level of 6-8 pH is provided that cleans, deodorizes, and sterilizes without any chemicals. The FRS water is pollution free, non-chemical and water based solution. The original and the resulting end material (or component) in the process of producing FRS water is simply water (H2O). Using transformation of water molecules by pretreatment and electrolysis processes, water is transformed to Free Radical Solution water wherein the free radicals in the FRS water solution add the very unique (physical) characteristics and functions that makes this water different from regular water (physically). The transformation is not chemical, but a physical change of atoms or molecules in water, i.e. the H2O molecules of water are transformed into different types of free radicals.

Abstract: A disc having a plurality of slits radially each of which have approximately the same width as a diameter of a photoreceptor of the sensor, and a rotary chopper, are arranged to coaxially rotate. When one of the slits faces a sensor, the disc and the chopper are rotated at a rotational speed so that the incident infrared radiation into the sensor is chopped 2-16 times by the chopper. At least two sets of sensors, each set of which comprises a plurality of sensors for sensing infrared radiation of different wavelength bands to one another, the sensors being arranged behind the chopper and the disc along a radial direction centered at the rotational axis of the chopper, are provided.

Abstract: A particle packing apparatus which includes a particle distributor capable of forming a concave-conical packed surface upon scattering of particles in a steady state and having a parameter with which to control the size of the cone and a packing monitor capable of continuously detecting the entire packed surface condition is provided. A concave-conical packed surface of the particles scattered in a steady state is formed by the distributor while the packing monitor is continuously detecting the formation of the packed surface and intermittently or continuously the parameter of the particle distributor is controlled to reduce the cone size gradually and form and deposit, on the inner side of the concave-conical packed surface, successively smaller packed surfaces at predetermined intervals or uninterruptedly, whereby a flat, smooth packed surface is formed. When scanning the deposit surface with laser light, detecting the reflected light, and measuring the deposit height by trigonometry, it is image-processed.

Abstract: A refractive index sensor of a total-reflection type comprises a waveguiding layer of a cladding/core/cladding waveguide structure formed on a substrate. The waveguiding layer has an input face connected to either a single optical fiber or a plurality of optical fibers for injecting a light(s) into the layer, a detection face which, obeying Snell's law, totally reflects/transmits the light beam or beams that have arrived there with an expansion angle from the optical fiber or fibers and which constitutes a surface with which a material whose refractive index is to be measured comes in contact, and an output face which outputs the light reflected from the detection face and is connected to an optical detector. The refractive index of the material of interest is detected from a bright-dark boundary of the presence of the corresponding total reflected light from the detection face. With no need of a bulk prism or lamp-type light source, the sensor is small in size and high in sensitivity.

Abstract: A fire sensing system, a process for sensing a fire and an environment monitor are disclosed. The system includes infrared sensors with sensing wavelength bands sensing an infrared radiation from an infrared source. One of the sensing wavelength bands is a CO.sub.2 -molecular resonance radiation wavelength band. The system determines whether a disastrous fire occurs or not on the basis of outputs of the sensors and a change in a ratio of the outputs. The process computes the temperature of the infrared source from a ratio of outputs of infrared sensors with at least two sensing wavelength bands of an infrared radiation from a monitored area, produces the intensity of infrared radiation of either of the bands from the computed temperature and computes a heating area from the intensity and the output of a corresponding infrared sensor. The process determines the progress of a fire.

Abstract: Infrared rays radiated from a moving object is converged into a plurality of infrared ray detectors by optical system. Detecting area is instituted by the optical system so as to put the infrared rays into a plurality of the infrared ray detectors with time difference therebetween. Signal processing unit produces a detecting signal when there is a predetermined time difference between signals produced by a plurality of the infrared ray detectors. It is possible to avoid wrong operation which is caused by popcorn noise and a differential noise having a bit of time difference caused by temperature gradient in space. Forming a curved imaginary boundary line, a plurality of detecting zones are disposed at out side and inside of the curved imaginary boundary line to detect the object invading from any direction.
