Title: Preparation of anthraquinone intermediate
Inventor: TAKESHITA AKIRA
IPC: C07C225/36
Filed: 1980-05-29
Abstract: PURPOSE: To obtain 1-amino-2-bromohydroxyanthraquinone, useful for the dye industry, in high yield, by the dibromination and the hydrolysis of 1-aminoanthraquinone in the presence of an aliphatic monocarboxylic acid in a specific amount.  
     CONSTITUTION: 1-Aminoanthraquinone is dibrominated in sulfuric acid in an amount ≥50wt% or fuming sulfuric acid in an amount ≤10wt% in the presence of an aliphatic monocarboxylic acid (e.g. acetic acid, propionic acid, etc.) at a molar ratio of 0.05W1.5, preferably 0.1W1.4, to give 1-amino-2,4-dibromoanthraquinone. After increasing the concentration of the sulfuric acid to ≥95% if necessary, the product is, without isolation, hydrolyzed preferably at 100W140°C in the presence of boric acid (preferably 1W3 molar ratio) to give the aimed intermediate.  
     EFFECT: The formation of blue impurities and tarry component as by-products can be inhibited in the bromination, and the resultant disperse dye provides clearly dyed articles.

Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To enable an output of a long warning signal even after a forced warming signal is stopped by an erroneous judgment, and use conveniently. SOLUTION: A human body is detected only by a heat wire sensor part 1 before first confirmation period elapses just after power-on, and a warning signal is stopped unless the heat wire sensor part 1 outputs a human body detection signal within the first confirmation period, and a second confirmation period starts from stop of this warning signal, and it is confirmed whether or not the heat wire sensor part 1 outputs a human body detection signal before the second confirmation period elapses.  Unless the heat wire sensor part 1 outputs the human body detection signal within the second confirmation period, environmental wave receiving data are acquires and updated, and if the heat wire sensor part 1 outputs the human body detection signal within the second confirmation period, an off-delay period is set to a first off-delay period to output immediately a warning signal, and then if it can be confirmed that the heat wire sensor part 1 does not output the human body detection signal within the first off-delay period, the environmental wave receiving data is acquired and updated, and also an off-delay period is set to a second off-delay period.

Inventor: ABE MITSUO
IPC: G11B5/31
Filed: 1983-04-27
Abstract: PURPOSE:To obtain a thin film magnetic head with ease of processing and gap bonding of a center core and high yield at the manufacture process by using a glass member for bonding having respectively a different melting point temperature so as to form the 1st gap and the 2nd gap. CONSTITUTION:The strength at processing is improved remarkably, because the processng of a center core block 10c in a process (d) is conducted in the state of a core block 10b' bonded and held by a side core block 10a. Further, the forming of two gaps is conducted twice in processes (c) and (e). Then, in comparison with a conventional method conducting the forming at a time, the track matching job is performed easily thereby improving the accuracy of a track width and a track position. Moreover, in order to execute it, the bonding glass member for forming the 1st gap 2a and the 2nd gap 2b is used differently and the working temperature is used as, e.g., 600 deg.C and 500 deg.C respectively so as to provide a temperature difference of 100 deg.C.

IPC: H01M4/52
Filed: 1981-05-14
Abstract: PURPOSE:To improve the discharging property of an alkaline battery employing nickel as the active material of the anode, by adding titanium and/or a titanium compound to the nickel electrode of the battery and providing an alkaline electrolyte containing lithium ions, to heighten the coefficient of utilization of the nickel electrode. CONSTITUTION:80wt% of pre nickel hydroxide powder as an active material, 5wt% of metallic nickel powder as an electroconductive agent, 5wt% of polyester as a binder and 5wt% of titanium oxide as an additive are mixed together well. The mixed powder is preparatorily molded as pellets. Each molded pellet is coated with a wire net of 50-200mesh and then finally molded, thereby providing an anode. Since the titanium compound and lithium ions are present together, the lithium ions act to the titanium compound so that the lithium ions come into the titanium compound. The resultant lithium-titanium compound exerts a desirable influence upon the electricity charging efficiency of the nickel to heighten the coefficient of utilization of the nickel electrode.

IPC: G06F13/42
Filed: 1995-03-30
Abstract: PURPOSE: To provide a communication control equipment and its method in which optimum transmission speed is set automatically while maintaining normal communication. CONSTITUTION: A recognizing part 111 detects the change of a PtrClk signal to show the transmission of data, and reads a status signal after the lapse of delay time set in a delaying part 110. A delay time adjusting part 112 judges whether the communication of the status signal by the recognizing part 11 was executed normally or not. On the basis of this judged result of the propriety of the communication, a delay time setting part 112 changes the delay time set in the delaying part 110. The delay time setting part 112 sets the minimum delay time within a range in which the normal communication is executed in the delaying part 110 by trying the communication plural times.

Filed: 1980-06-03
Abstract: PURPOSE:To accomplish an excellent demodulating characteristic against variance in input frequency and temperature, by inserting a SAW filter having the same delay time and temperature characteristics to a Nyquist filter side and a limiter  circuit side respectively. CONSTITUTION:An input signal from an input terminal IN is amplified to a specified level at an intermediate frequency amplifier AMP and distributed at a hybrid HYB. One signal distributed is fed to a video detection circuit DET via a Nyquist filter SAW1 by a SAW filter. Further, another signal is picked up for a video carrier at a limiter LIM through a video carrying filter FvBPF, and this is fed to the circuit DET via a band pass filter SAW2 consisting of SAW filters. In this case, by manufacturing the filters SAW1 and SAW2 on the same board, the temperature characteristics are entirely the same and negligible. Further, the filters SAW1 and SAW2  are designed to have the same delay time easily.
