IPC: C07C205/48
Filed: 1994-09-01
Abstract: PURPOSE: To highly selectively obtain a 1-nitroanthraquinone in high yield by carrying out reaction with increasing the ratio of sulfuric acid in the reaction system in nitrating an anthraquinone with sulfuric acid and nitric acid. CONSTITUTION: An anthraquinone of formula I (X is a halogen, a 1-4C alkyl, a 1-4C alkoxy, OH, carboxyl or sulfonic group substituted at the 1-, 2-, 3- or 4-position; (m) and (n) are each 0-3; Y is the same group as that of X which is substituted at the 5-, 6-, 7- or 8-position) is nitrated with sulfuric acid and nitric acid to give a 1-nitroanthraquinone of formula II. In the reaction, the ratio of sulfuric acid is increased by stages and the reaction is carried out by raising the ratio of sulfuric acid in the mixed acid with time or dropping the mixed acid and then adding sulfuric acid to attain high yield and high selectivity. Anthraquinone and 1-bromo-3-anthraquinonesulfonic acid are especially preferable as the anthraquinone.

Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To produce a kovar sintered compact having a coefficient of thermal expansion equal to those of hard glass and ceramics and also having mechanical properties equal to those of a refined material. SOLUTION: Carbon powder is added to a powdered raw material which has a composition consisting of, by weight, 28-32% Ni, 15-18% Co, and the balance essentially Fe and containing >=0.3% oxygen as an inevitable impurity. The resultant powder mixture is compacted, or, a binder is added to the powder mixture to form a kneaded material and further this kneaded material is injection-molded. Then sintering is carried out in a nonoxidizing atmosphere. By this method, the sintered compact containing <=0.05wt.% C and <=0.3wt.% oxygen and having >=94% relative density can be obtained.

Title: Control of automatic transmission for vehicle
Inventor: ASADA TOSHIYUKI
IPC: F16H59/58
Filed: 1990-08-07
Abstract: PURPOSE:To prevent deterioration of fuel consumption by unnecessary high speed rotation of an engine by comparing a yawing state at the time of revolution and a standard state with each other and changing a speed change step selected on the basis of a travelling condition on the basis of this compared result. CONSTITUTION:A yaw angle speed at an ideal state gradually grows larger as time passes or gradually becomes smaller so that the yaw angle speed comes to be almost a constant value, and a yaw angle speed in a high car weight state increases a little in its rate of increase at first and gradually more, and at one time it comes to be higher than the yaw angle speed in the ideal state, and thereafter gradually decreases and comes to be lower than the yaw angle speed in the ideal state and finally it is converged upon the yaw angle speed in the ideal state. Accordingly, in the case of a high car weight, the phase of the yaw angle speed comes to be different against the ideal state. Consequently, when the difference between an actual yaw angle speed and the ideal yaw angle speed is gained and its value exceeds a standard value previously specified, a speed change step train for the high car weight is selected, and when it is less than the standard value, a speed change step train for ordinary car weight is selected, and the yaw angle speed is set to either of them on the basis of a travelling condition.

Filed: 1989-08-12
Abstract: PURPOSE:To obtain a stabilized output signal by regulating an intermittent analog signal from a receiving part so that it becomes an analog signal that ranges over one intermittence time again after converted to a digital signal with the receiving part, and converting to an analog signal. CONSTITUTION:An intermittent signal outputted from a transmitting part (a) is converted to a digital signal by an A/D converter 3 and converted again to an analog signal by a D/A converter 8, and on this occasion, an adjustment is made so that the time of that analog signal becomes one intermittence time, therefore, it becomes possible to make the waveform outputted from the D/A converter 8 successive to the adjusted output signal of next intermittent signal. Accordingly, when a transmission part (b) short-circuits at a train axle and the input level to the A/D converter 3 is changed, the output waveform of the D/A converter 8 also accurately changes in response to the change, therefore, the action of a track relay TR by judging the level of this output waveform can be accurately performed.

Abstract: PURPOSE:To promote efficiency and to improve accuracy by packing an air permeable reducing catalyzer of titanium or platinum series, etc. in a reducing reaction furnace and passing a sample gas of 700-1,050 deg.C therethrough to reduce phosphor or sulfur to hydride. CONSTITUTION:The sample gas from a reducing reaction furnace 2 is passed through a cooler 4 to remove the moisture, and is circulated to the furnace 2 through dryers 6, 7 by a changing-over cock 5. In this case, gaseous hydrogen is introduced to a circulation passage 3 from a cylinder 9 to maintain the condition unber reducing atmosphere. Next, if phosphor or sulfur in the gaseous sample of 700-1,050 deg.C is changed to uniform hydride, a fixed quantity of the gaseous sample is taken out from the passage 3 and sent to a measuring system 10 such as a flame photometric detector. Whole phosphor or surfur component in the gaseous sample is changed to uniform hydride such as PH3 or H2S, and is fed to a column to separate and detect it. Thereby, the analysis is made efficient and the accuracy can be improved.

Abstract: PURPOSE:To increase an allowance degree from a structural planning aspect and to specify an arbitrary absolute origin, by providing separate optical lattices different in a pitch and making it possible to generate a reference pulse signal on the basis of the phase difference between sets from the relation of both optical lattices. CONSTITUTION:A main scale 10 having a measuring optical lattice 13 and an origin detecting optical lattice 15 different from said lattice 13 in a pitch provided thereto and an index scale 20 provided with measuring and origin detecting reference optical lattices 23(23A, 23B), 25(25A, 25B) opposed to each other are moved relatively. Whereupon, by the irradiation of the non-parallel beam from a non-parallel illumination system 40, electric signals having phase differences theta1, theta2 are respectively outputted to the optical lattices 23, 25 from the corresponding photoelectric converter 30. A reference signal generating circuit 70 inputs the electric signals having the phase differences theta1, theta2 and generates a reference signal when the phase difference (theta1-theta2) between sets becomes a specific value. Therefore, by utilizing this signal, the absolute origins of both scales 10, 20 can be arbitrarily specified. The relative moving displacement quantity of both scales 10, 20 is detected by the processing of the signal from the converter 30.

According to this method, the pressure fluctuation of the combustion chamber 10 can be reduced. Further, sound attenuating effect can be retained whereby the generation of abnormal combustion noise or vibration combustion noise can be prevented.

Title: Refrigerating machine
Inventor: OSHIMA MASAKAZU
IPC: F25B41/04
Filed: 1991-08-22
Abstract: PURPOSE:To free the operation, even where a general-purpose temperature controller having no limiter is in use, from the problem that the suction pressure of the compressor may decrease excessively by providing in parallel with a flow-rate control valve a bypass equipped with a means of resistance to refriger ant. CONSTITUTION:In parallel with a flow-rate control valve 5, which is placed between an evaporator 4 and the inlet of a compressor 1 for the control of the flow-rate of the refrigerant 1a, a bypass 10 equipped with a capillary tube 9 as a means of resistance to the refrigerant 1a is provided. Even when, for example, the heat load has considerably fallen owing to some cause and a signal from a temperature controller 7 brings the flow-rate control valve 5 to a complete closure in valve opening or to a throttled state close to a complete closure, the refrigerant 1a keeps flowing into the compressor 1 in small amounts so that there is no possibility of the suction pressure being reversed to a negative pressure at the compressor 1. Thus, this method enables the refrigerating machine to continue to operate normally.
