Title: Force balance type pressure transducer
Inventor: KOBAYASHI KAZUSHIGE
IPC: G01L9/14
Filed: 1990-09-29
Abstract: PURPOSE:To make it possible to realize the highly sensitive, highly accurate response by balancing in a noncontact manner the pressure to be measured which is applied on magnetic fluid and the magnetic force of an electromagnet which is applied on the magnetic fluid. CONSTITUTION:When pressure PM of fluid to be measured is applied on a thin film 2, the pressure is transferred to magnetic fluid 5 and displaced into pressure PL. The pressure PL acts on the thin film 3, and force FL is generated. An electromagnet formed of a magnetic core 6 and a coil 7 attracts the fluid 5 upward. Therefore, force FF is generated. The force FF depends on a current IF. The force FF is proportional to the square of IF. Since the strain generated in the thin film 3 is proportional to the difference between two forces FL - FF, the strain is detected with a strain detector 9. The current IF is controlled so that the difference between two forces FL - FF becomes 0 with the detector 9 and a current controlling amplifier 10. Since the force FL is proportional to the pressure PM and the force FF is proportional to the square of the current IF, the current IF is proportional to the square root of the pressure PM when a closed loop is balanced. Namely, the pressure PM is converted into the current IF.

Title: Catalyst type combustion appliance
Inventor: MATSUMOTO IKUO
IPC: F23D14/18
Filed: 1984-12-12
Abstract: PURPOSE:To provide a Schwank burner in which a sufficient complete combustion can be carried out even if a burning volume is metered by a method wherein white catalysts are carried on the surface of the burner. CONSTITUTION:A spark is generated near the surface of a flame port plate 1 when a burning unit is ignited or a small flame is formed at an outlets of small holes 2 with an igniter of pilot flame. Catalysts 3 carried on the surface of the flame port plate 1 having a radiation heat received from small flames are approached to such a temperature as its value corresponds to that of oxidation and activation gradually and a part of the flame combustion is transferred to a catalyst combustion. Under a combustion system where combustion volume is normally increased, this effect may not be expected so much. However, in case that the burning amount is metered, an excessive effect may be provided and a superior combustion can be maintained without performing an incomplete combustion under a catalyst combustion. If the color of the catalyst 3 is white, the radiation amount can be restricted, the temperature of the flame port plate 1 is also increased and the active catalyst can be maintained. This becomes a cause to provide a wide range of combustion.

Title: Light wave interference device preventing reverse surface reflected light
Inventor: NAKAZAWA KOJI
IPC: G02B5/00
Filed: 1984-12-14
Abstract: PURPOSE:To remove interference fringes formed by reverse-surface reflected light from an optical component such as an objective and to improve precision by setting a beam splitter so that its incidence surface and projection surfaces do not cross the optical axis of irradiation light at right angles. CONSTITUTION:This device guides the irradiation light 3 to a sample-side objective 7 and a reference-mirror side objective 8 by the beam splitter 20, whose incidence surface and projection surfaces 20-1 and 20-2 are not at right angles to the optical axis of the irradiation light 3. For the purpose, the beam splitter is formed in the sectional shape of, for example, a rectangle, parallelogram, or diamond. Consequently, reverse-surface reflected light beams 5 and 6 from the projection surfaces 20-1 and 20-2 and reverse-surface reflected light from the objectives deviate greatly from regular reflected light 13 and do not strike a photodetection part, so no interference fringe is formed.
