Title: Production of 5-norbornene oxetane compound
Inventor: NAKAMURA HITOSHI
IPC: C07D305/14
Filed: 1990-03-03
Abstract: PURPOSE:To obtain in a high yield under mild conditions the title compound useful as an intermediate in the organic chemical industry by reaction of a 5-norbornene-2,2-dimethanol compound with a sulfonyl chloride followed by ring closure with a base. CONSTITUTION:Firstly, a 5-norbornene-2,2-dimethanol compound of the formula (R is H, alkyl or aryl) is allowed to react with a sulfonyl chloride in a solvent such as ethyl ether at 0-50 deg.C into a monosulfonyl ester. In this case, hydrogen chloride is produced, which is eliminated by such means that a base as dehydrochlorinating agent is made to exist in the reaction system. Thence, the above ester is made to react with a base (e.g. sodium hydride) in a solvent such as THF at 0-50 deg.C to obtain the objective compound. The polymers derived from the present compound are useful as e.g. engineering plastics.

Title: Stirring method in refining molten iron in vessel
Inventor: TAGUCHI KIYOMI
IPC: C21C1/02
Filed: 1980-04-19
Abstract: PURPOSE: To enhance the effect of stirring the melt by specifying the ratio of the inside diameter of a gas injection hole to that of a lance, when refining molten iron or steel by placing it in the vessel and stirring it with an inert gas blown into it through an immersed lance.  
     CONSTITUTION: When refining the molten pig iron or steel in a closed vessel 4 by stirring and contacting it with molten slag 8, the stirring of the melt is conducted by blowing Ar gas into the melt through the lance 1. A T-shaped two-hole type lance or an L-shaped single-hole type lance is used as the lance 1, the ratio d/D of the inside diameter d(d 1 , d 2 ) of the gas injection hole to that D(D 1 , D 2 ) of the lance being specified in the range of 0.1≤d/D≤0.5. Since the gas blown in is injected horizontally into the molten steel and is dispersed uniformly before migrating vertically upwards, the stirring of the melt and that of the melt with the molten slag are conducted efficiently, resulting in an enhanced refining effect.

Filed: 1991-03-18
Abstract: PURPOSE:To enable use of a short arc Xe tube by utilizing the relation between a tube current of an internal light discharge tube (Xe tube) and a collector voltage of gate insulation type bypolar transistor(IGBT). CONSTITUTION:An emission start signal is applied to a trigger circuit 25 so as to trigger an Xe tube 11 by operating the trigger circuit 25. At the same time, a signal is sent to a gate control circuit 19 so as to operate the control circuit 19 to turn on an IGBT 18. Thus, light emission of the Xe tube 11 starts. When a tube current starts to flow, voltage of (IGBT on-resistance X tube current) is generated in the collector 18c of IGBT 18. This voltage is detected by a collector voltage detection circuit 20, and the signal is sent from the detection circuit 20 to the control circuit 19 before it exceeds the withstand current of the IGBT 18, to turn off the IGBT 18. Then, light is emitted while the inside of the Xe tube 11 is still ionized. When an optimum quantity of light is obtained by the above repetition, emission is stopped.

IPC: G11B7/135
Filed: 1983-03-30
Abstract: PURPOSE:To eliminate difficulty of substrate production and complicatedness of a servo system to improve S/N and extend functions by alloting functions to two laser beams different in focus position. CONSTITUTION:A row of dots which are written already are detected with a beam A, and the focus position and the center position of the beam A are so set that they are matched to this row of dots, and write and read are performed with a beam B. In case of read, servo is applied to a row of dots on the inside the row of dots by the beam A to read the row of dots by the beam B, and the interval between beams is fixed by a head to output a signal while tracing the row of dots accurately, and the noise is small because groove information is not included. Since a medium without grooves can be used as a substrate, its formation is simplified to improve the error rate. Parallel read is possible with two beams, and a high-speed data processing is possible.

Abstract: PURPOSE: To prevent reduction in insulation by forming a partition layer comprising metal components on a gate electrode from just above, and by forming a conical electric field emission cathode chip after narrowing an opening of a cavity. CONSTITUTION: A plurality of negative electrodes 12 are formed on a lower part base 10 in a column direction, and the electrode 12 is formed with an electron emission negative electrode 16 and an insulation layer 14. A plurality of gate electrodes 18 are formed on the insulation layer 14 in a row direction, and a cavity 15 or a hole are formed at a position opposite to the electrode 18 and to the negative electrode 16. At this time, the negative electrode 16 does not form a single layer constituting a single component, and has a multilayer structure where a component of a lower end part is different from that of an upper end part. In this manner, a conical electric field emission cathode chip is formed having an extremely fine leading end.

Filed: 1989-03-07
Abstract: PURPOSE:To not wastefully control ignition timing by installing a signal processing circuit, having voltage higher than the working supply voltage of a microcomputer as an operating circuit voltage, and a controlled variable changing circuit, respectively. CONSTITUTION:A knock detecting mode detector 22d uses voltage of a battery 24 presently inputted into a computer unit 22A as a detecting signal, and monitors the voltage value. When the voltage of the battery 24 is more than 8.5V, a fuel control part 22a, an ignition timing control part 22b and a knock detecting part 22c are all secured with each regular control operation, so that the detector 22d will not generate its output. Next, when the battery voltage becomes lower than 8.5V, the detecting part 22c comes into an unstable operating state due to size and speed of a ripple of the battery voltage, so that this detector 22d generates its output. When a knock signal has been transmitted form the detecting part 22c, the control part 22b judged it as an erroneous knock signal and it is made so as not to be directly used.
