Title: Oxygen sensor
Inventor: IPPONMATSU MASAMICHI
IPC: G01N27/12
Filed: 1993-08-25
Abstract: PURPOSE:To obtain an oxygen sensor which excels in anti-temperature characteristic and responsiveness with a simple structure by forming an oxygen concentration detecting section from a compound in which a specified perovskite type oxide is doped with alkaline earth metal. CONSTITUTION:An oxygen concentration detecting section (thin film) is formed on a substrate 10 by a laser abrasion method or the like. The detecting section 12 is formed from a compound in which a perovskite type oxide of an ABO3 type comprising ittrium or lanthanoid at an A site and chromium or manganese at a B site is doped with alkali earth metal. To measure electric conductivity of the thin film 12 by a DC 4 terminal method, an ammeter 18 is connected in series to a power source 16 through a terminal 14. A voltmeter 22 is connected through a terminal 20. As the electric conductivity of the thin film 12 varies with the concentration of oxygen in the atmosphere, the electric conductivity of the thin film 12 is measured in various atmospheres with the concentration of oxygen known is measured beforehand. This clarifies a correspoding relationship between the concentration of oxygen and the electric conductivity.

Title: Refrigerating cycling apparatus
Inventor: TANABE YOSHIHIRO
IPC: F25B1/00
Filed: 1993-08-25
Abstract: PURPOSE:To protect a compressor by making a start-up pattern at the start-up of a refrigerating cycling apparatus into a low-speed start-up. CONSTITUTION:For example, in the case of a cooling operation, a refrigerant of high pressure and high temperature is conducted to an outdoor heat exchanger 3 where a refrigerant gas is liquefied to discharge heat of condensation outdoor. The gas further liquefied is made into a gas-liquid two-phase refrigerant of low pressure and low temperature by a decompression device 4 to be conducted to an indoor heat exchanger 7 where the refrigerant absorbs heat from an indoor air to evaporate to be made into a gas refrigerant of low temperature and low pressure. Thus a cooling operation is performed. Then a refrigerating cycling operation is performed, in which the refrigerant is fed into a suction port 1a of a compressor 1 through a four-way valve 2. In this case, a low-speed start-up operation is performed to start up the compressor 1 while putting hours therein. Accordingly, it is possible to protect the compressor 1 against abnormal heating due to ill installation or the like.

Title: Chromatography apparatus
Inventor: MORITA HIROSHI
IPC: B01D61/22
Filed: 1986-09-09
Abstract: PURPOSE:To eliminate labor and time for filtering a sample liquid with a semi-permeable membrane beforehand, by employing a laminate of semi-permeable membranes with a division molecular weight larger than the max. molecular weight of objective material to be separated as the filler for a column. CONSTITUTION:The periphery of semi-permeable membranes similar to the internal shape of a cylinder 1 adheres to one another with an adhesive to form a laminate 2 of scores to more than one hundred sheets of semi-permeable membranes, which is placed on end caps 3 and 4. Then, the end cap 4 is loaded at other end of a cylinder 1 and the laminate 2 is fixed with both end caps 3 and 4. A fluid 5 such as adhesive is injected into the cylinder 1 laid sideways through a hole 1' to fill spaces on the circumference of the laminate 2 and on the internal circumference of the cylinder 1 and solidified to make a column. With such an arrangement, solutes in the material to be separated can be eluted and separated from the laminate 2 of semi-permeable membranes sequentially starting from smaller molecular weight. This enables the removal of solutes and suspension components larger than the division molecular weight of the semi-permeable membranes by filtering as contained in the sample liquid, thereby eliminating labor and time for filtering the sample liquid with a semi-permeable membrane beforehand.
