A perovskite type manganese oxide thin film capable of working at temperatures within an electron cooling range and a high sensitivity infrared sensing element using the same thin film are disclosed. The thin film of perovskite type manganese oxide containing an element Ca or Sr and elements La, Mn and O is characterized in that a metal-insulation phase transition point of the thin film lies within a range of temperatures obtainable by a thermoelectric cooling method. The perovskite type manganese oxide is a thin film produced by a sol-gel method and the film is used for manufacturing an infrared sensing element.

Yogurt containing lactic acid bacteria and Bifidobacteria, to which one or more kinds of sweet substances selected from a group consisting of palatinose, palatinite, maltose, maltitol, starch syrup, reducing starch syrup and trehalose as well as a refined fish oil containing highly unsaturated fatty acids such as DHA and EPA are added, is packed in an oxygen blocking hermetic package. The yogurt contains highly unsaturated fatty acids and has good flavor and taste, as well as excellent product quality stability, and does not generate a fishy odor during normal storage periods.

In a brushless motor, the number of coreless armature coils is set to 3n when the number of magnetic poles of a magnet for a magnetic field is set to 2n where n is a positive integer. An opening angle of each of the armature coils is set to 360/3n degrees. A notch portion is formed in an outer circumferential portion of the magnet for a magnetic field. A recessed portion is formed by this notch portion and an inner circumferential portion of a yoke. The recessed portion constitutes a groove for correcting a balance of each of the magnet for a magnetic field and a rotating body when this magnet and the rotating body are rotated. A motor housing and a harness are electrically connected to a printed board. The housing is connected to the ground through this harness and a harness for power. In this brushless motor, a magnetizing frequency is reduced and driving efficiency of a control circuit can improved when the brushless motor is rotated at a high speed. Further, it is possible to prevent an iron or copper loss from being caused so that an increase in temperature of the brushless motor can be restrained.

A face opposing type motor has a rotor yoke fixed to a hollow rotating shaft disposed in a non-contact bearing device; the non-contact bearing device having a fixed shaft inserted into the hollow rotating shaft; a rotor magnet held by the rotor yoke; and a driving coil substrate having a face opposed to the rotor magnet. The rotor yoke has a rotor magnet fitting portion fitted to an outer circumferential face of the rotor magnet so as to hold the rotor magnet by this rotor magnet fitting portion. In accordance with such a structure, it is possible to provide a reliable face opposing type motor having an excellent quality and cheaply manufactured by improving a system for holding a rotor magnet.

An optical rotary encoder is formed by a control pulse generator portion and a selector switch portion which are of the unitary construction. The control pulse generator portion is formed by a code plate having a plurality of alternately formed reflecting and non-reflecting areas, a plurality of light emitting and receiving elements facing the code plate and an inner shaft for rotating the code plate. The selector switch portion is formed by a second code plate having a plurality of light transmitting apertures, a plurality of light emitting elements facing the second code plate, a plurality of light receiving elements provided on the opposite side of the second code plate from those light emitting elements and an outer shaft for rotating the second code plate. The inner and outer shafts are connected to each other and have a common axis of rotation.

A code wheel for use in a reflective optical rotary encoder includes a code wheel body formed of a light-reflective material, and a photosensitive layer directly coated on a flat surface of the code wheel body and exposed to light to produce angularly spaced non-reflecting surfaces, thereby providing alternate reflecting and non-reflecting surfaces on the code wheel body. The speed and direction of rotation of the code wheel can be detected by radiating light onto the reflecting and non-reflecting surfaces and detecting light reflected by the reflecting surfaces.

An apparatus for determining total carbon in each one of a plurality of discrete liquid samples comprises a reactor (13), and a pump (12) and flowline (11) for maintaining a continuous flow of a liquid containing an oxidizing agent into the reactor (13). The liquid samples are introduced in succession into the reactor (13), either by means of a syringe injection port (19) in the flowline (11), or by means of a rotary valve (203) and sample loop (204) in a recirculation line (202) through which carbon-free liquid is withdrawn from and circulated back to the reactor (13). A mercury vapor lamp (17) is immersed in the liquid in the reactor (13) for irradiating the liquid sample and the oxidizing agent in the reactor (13) with ultraviolet energy in order to oxidize to carbon dioxide any carbonaceous matter in the liquid sample. A sparger (20) is provided to remove the carbon dioxide so produced from the reactor (13); and a carbon dioxide detector (24) is provided to measure the carbon dioxide produced as a result of the oxidation of carbonaceous matter in the reactor (13). Electronic integrator circuitry (25) provides a measure of total carbon present in the carbon dioxide produced in the time interval during which carbonaceous matter in each liquid sample is being oxidized.
