Title: Reactor for producing ethylene oxide
Inventor: KAKIMOTO YUKIHIKO
IPC: C07D301/10
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To obtain the subject reactor capable of improving the selectivity when carrying out a vapor-phase oxidation of ethylene by treating a part of the surface of the reactor contacting with a reactant gas with a solution of a nitrite. SOLUTION: This reactor is a carbon-steel shell-and-tube type reactor for producing ethylene oxide by oxidizing ethylene in the presence of a silver- carrying catalyst, and has at least a part of the surface of the reactor, contacting with the reactant gas (e.g. the inner surface of each reaction tube and the inner surface of a tube plate face), and treated with a solution of a nitrite. The solution of the nitrite is preferably an aqueous solution of 0.1-10 wt.% sodium nitrite. The formation of an aldehyde or the like is thought to be suppressed because an iron oxide coating membrane is formed by the surface treatment.

Title: Analysis method with high-sensitivity liquid chromatography
Inventor: FUSHIMI KATSUO
IPC: G01N30/62
Filed: 1983-11-24
Abstract: PURPOSE:To enable reduction of the noise appearing in synchronization with the reciprocating motion of a plunger by providing a pressure-voltage transducer which detects the pressure fluctuation of the plunger. CONSTITUTION:A pressure fluctuation arises in flowing liquid by the reciprocating motion of a plunger pump 3 which supplies the eluate from an eluate tank 2 to a sepn. column 1. The pressure fluctuation is converted to a voltage fluctation B by a pressure-voltage converting sensor 6 provided in the flow passage after the outlet of the pump 3. The signal B is supplied to a control circuit 7 for noise suppression constituted of an amplifier 71 and a semiconductor devider 72. On the other hand, the eluate receives the injection of a sample from a sample injecting part 4 and is conducted to the column 1 and a detector 5. The pressure fluctuation by the reciprocating movement of the plunger is detected as a superposed chromatography C from the detector 5 and is supplied via the amplifier 71 to the divider 71. The output C is added so as to be a numerator of the devider 72 and the output B from the sensor 7 is added so as to be a denominator, by which the noise occuring in the pressure fluctuation is suppressed.

Filed: 1990-08-27
Abstract: PURPOSE:To reduce errors of decision and to automate by a simple device by providing different identifications at respective connection sets, connecting components to corresponding sets, and identifying an identification mark not covered with the component, thereby reversely identifying a terminal connected to the component. CONSTITUTION:A position in a board of a component connecting part for setting a code value of a printed board 4a in which a component is mounted is decided in response to the board 4a. The board 4a is so moved that the part falls within a reading range of a bar code reader 5a. The reader 5a reads a bar code 3a. In this case, since the code 3a corresponding to the set of a terminal connected with the component 2a is covered with the connected component 2a, it cannot be identified, and all the code 3a not covered are read. The information is sent to a bar code analyzer 6a. The analyzer 6a analyzes the signal, reversely identifies the set of the terminal connected to the component 2a, and identifies the corresponding type.

IPC: H02K17/30
Filed: 1994-08-24
Abstract: PURPOSE: To provide an induction motor provided with a detector for the axial displacement of its rotor that will produce no error due to the influence of load current, by devising the structure of skewed slots of the induction motor. CONSTITUTION: In a detector, a pair of magnetoelectric transducers 11, 12 are placed on either side of a stator core 22 and outside the main magnetic field produced in the stator. The output of the pair of the magnetoelectric transducers is wired so that unbalanced leakage magnetic flux on either side of the stator core will be output as differential output. Thus the axial displacement of a rotor 21 is detected on the basis of the degree of unbalance of leakage magnetic flux. An induction motor is provided with such a detector. The skewed slots 25 in the rotor 21 and the stator core 22 of the induction motor are so adjusted that variations in the differential output of the pair of the magnetoelectric transducers 11, 12 will be less than those in leakage magnetic flux due to variations in the load of the induction motor.
