Title: Fluorescent lamp lighting device
Inventor: NIINAI KATSUHIKO
IPC: H05B41/24
Filed: 1988-06-10
Abstract: PURPOSE:To enable the stabilized lighting of two fluorescent lamps even at a low temperature by providing a timer circuit operating concurrently with the oscillation of an oscillation circuit and closing the first and second relay contacts for the predetermined time of initial lamp lighting. CONSTITUTION:When an oscillation circuit 8 is actuated and a timer circuit 19 is operated for closing the first relay contact 17 between the primary and secondary windings of the first oscillation transformer 9, the electrode of the first fluorescent lamp 1 is applied with high voltage to the ground equivalent to the sum of voltage of the first and second windins induced with the positive half-cycle of an AC current flowing to the primary winding only for a short time. As a result, the first fluorescent lamp 1 lights and then the first relay contact 17 opens, thereby enabling keeping the lighting of the first fluorescent lamp 1 on the low secondary voltage of the first oscillation transformer 9. The same process as aforementioned takes place between the second oscillation transformer 10 and the second fluorescent lamp 2. According to the aforesaid construction, two fluorescent lamps can stably light even at a low temperature with a simple low-voltage circuit comprising a small number of parts.

Title: Directly buried type transformer
Inventor: AKAIKE MASAHIRO
IPC: H01F27/18
Filed: 1986-06-20
Abstract: PURPOSE:To make it possible to bury a transformer directly in the ground for employment, by using a heat pipe to carry heat generated from a coil member to a heat-radiating member and by using a corrugated tube as a container for the heat pipe. CONSTITUTION:An insulating oil 5 fills a closed vessel 2, and a spiraled heat pipe 6 surrounding a coil member 1 on one end side is immersed in said insulating oil 5. On the other hand, the other end of the pipe 6 is led outside the vessel 2 and disposed in a heat-radiating member 7. The pipe 6 has a construction wherein a condensable fluid is injected as an operating fluid inside a closed corrugated tube 8 after a noncondensable gas is exhausted therefrom to make the inside of the tube vacuum and wherein a wick 10 having a porous structure to cause a capillary pressure inside the tube 8 is arranged. Thereby heat emitted from the coil 1 is released into the air by the pipe 6, and consequently a rise in the temperature of a transformer as a whole is prevented. The transformer having this construction can be buried directly in the ground for employment without providing a handhole.

Abstract: NEW MATERIAL:A DNA capable of coding a protein which inactivates the function of tabtoxin. USE:For creating plants resistant to Pseudomonas syringae pv. tabaci. PREPARATION:For example, Pseudomonas syringae pv. tabaci is cultured and collected and a chromosomic DNA is then separated by a conventional method and treated with a restriction enzyme to prepare a chromosomic DNA fragment. On the other hand, a plasmid pUC 13 of Escherichia coil is treated with a restriction enzyme and subsequently linked to the chromosomic DNA fragment of the Pseudomonas syringae pv. tabaci and then inserted into Escherichia coli to carry out transformation. The resultant transformant is subsequently cultured in an agar culture medium containing ampicillin to culture the grown colony in a culture medium containing tabtoxin and thiamine.

Title: Variable voltage variable frequency induction motor controller
Inventor: IMAZEKI TAKASHI
IPC: B60L9/18
Filed: 1985-07-02
Abstract: PURPOSE:To effectively operate an electric motor vehicle while avoiding the hunting vibration of the vehicle due to a motor torque pulsation of a fork lift truck by increasing a slip frequency and a motor applying voltage at light- load and extremely low-speed operation time. CONSTITUTION:When an induction motor 10 is operated at an extremely low speed, a slip frequency command fS is increased by the characteristic 100 of a slip frequency command generator 14 and the characteristic 102 of a modulation ratio calculator 16, a modulation ratio gamma is increased to increase each voltage command V. Thus, since the slip of the motor 10 is controlled to be increased at extremely low-speed operation time, the torque pulsation of the motor 10 is separated from the natural vibration frequency band of a fork lift truck. As a result, the hunting vibration of the truck due to the torque pulsation can be largely reduced.

Abstract: PURPOSE:To obtain the title production device capable of obtaining a spring material having high durability and high strength by providing a means for heating a carbon steel wire or an alloy steel wire to the austenitizing temp., a means for cooling the wire to the supercooled austenite temp., a means for reduction-drawing the wire by plastic working, and a means for quenching the wire. CONSTITUTION:A carbon steel wire or an alloy steel wire A is heated by the heating means 1 to the austenitizing temp., passed through the cooling medium 3 in a cooling bath 2, and cooled to the supercooled austenite temp. The steel wire A is passed through a drawing tool 7, and reduced. Since the tool 7 is kept at the same temp. as the cooling medium 3, the steel wire A is not cooled even when the steel wire A is brought into contact with the tool 7. Consequently, accurate isothermal transformation can be caused in the steel wire A while keeping the supercooled austenite state. The drawn steel wire A is quenched by the cooling means 8 provided in the vicinity of the outlet of the tool 7 to a temp. below the Ms point, and the structure is frozen in a short time.
