Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To obtain the subject high-purity compound without requiring a high temperature by halogenating a phthalic acid derivative in the presence of a catalyst. SOLUTION: A (substituted) phthalic acid or its derivative is halogenated by using an iodine-containing compound (e.g. potassium iodide) as a catalyst in fuming sulfonic acid at 100-160 deg.C to give a halogenated phthalic acid or its derivative. The phthalic acid or its derivative is nonsubstituted or substituted with I, Br, COOH, etc., and the derivative is preferably an anhydrous substance. Fuming sulfuric acid contains 5-65wt.% of SO3 and Br<2> or Cl<2> is used as a halogenating agent. The amount of the catalyst is 1-10wt.% based on the phthalic acid or its derivative. The objective halogenated phthalic acid is useful as an intermediate for dye, pigment, germicidal and fungicidal agent, flame- retardant polyester resin and epoxy resin and a flame-retardant additive for coating material.

Filed: 1986-06-19
Abstract: PURPOSE:To contrive to easily make uniform the composition and thickness of grown layers by arranging solution tanks of first and second solution reservoirs in a manner that each tank enters into another solution reservoir alternately so the growing solutions filling the solution reservoir communicate with each other. CONSTITUTION:This device is composed of a substrate holder 4 in which an InP substrate 1 is attached to a containing recess, a solution holder 5 provided with InP growing solution reservoirs 9 and InGaAsP growing solution reservoirs 10 which are separated from one anther, and a boat 6 for mounting the substrate holder 4 and the solution holder 5. The InP growing solution reservoir 9 and the InGaAsP growing solution reservoir 10 comprise plural solution tanks 9a-9d and 10a-10d respectively and the solution tanks 9a-9d and 10a-10d extend under a central partition 5a of the solution holder 5 and penetrate through the adjacent growing solution reservoirs 10 and 9. Because a capacity of the growing solution reservoirs 9 and 10 is large, the change of composition due to the exhaustion of a solute becomes small. Accordingly, the modulation of the growing conditions is not neccessary when forming multiple growth layers and the composition and thickness of the layers become uniform.

CONSTITUTION:After making to adhere a nitrate solution containing Bi, Si, and Cu as well as at least a kind of ingredients selected out of a group consisting of Cd, Zn, Mg, and Hg to the surface of a heat resisting insulating substrate, its substrate is dried. Then it is fried at a temperature 800-870 deg.C in an atmosphere of oxidation to form an oxide layer consisting of Bi-Sr-M (although M is Cd, Zn, Mg, and/or Hg)-Cu-O and the patterning of its oxide layer is performed. For example, a powder in which combined quantities of 1/2 mol Bi2O3, 1mol SrO, 1mol CdO, 2mol CuO are dissolved into nitric acid. An alumina substrate is immersed in a diluted nitric acid solution and its treatment makes its nitric acid solution stick to the alumina substrate. After drying its solution, its substrate is fired at a temperature 850 deg.C and then a resister shown in Fig. is obtained by patterning the formed thin film.

Filed: 1981-09-09
Abstract: PURPOSE:To enable accurate measurement of a relative distance and velocity by a method wherein the rapid lowering of a reception level below the prescribed level is detected without delay in time and thereby the compensation of a measured value is conducted. CONSTITUTION:A transmission unit 1 sends a beat signal obtained from a transmission wave to a detecting circuit 2, and a detection output is given to a low- pass filter 4 and a comparison circuit 6. The low-pass filter 4, which delivers a signal corresponding to the average of the level of the beat signal, can not follow a rapid change of the level. When the level of the beat signal changes rapidly, therefore, the output of the comparison circuit 6 turns ''1'', and when the level of the detection output lowers belows a reference voltage, the output of a comparison circuit 7 turns ''1'' as well. When the outputs of the comparison circuits 6 and 7 turn ''1'' simultaneously, the output of an AND circuit 9 turns ''1'', and compensation is performed by a relative distance measuring unit 10 and a relative velocity measuring unit 11.

Filed: 1995-05-18
Abstract: PURPOSE: To reproduce the content recorded arbitrarily in user's own voice at a predetermined selected time by providing a set knob and an operating switch capable of controlling the time and recording or reproducing. CONSTITUTION: A notice time set knob 7a is operated, and the hand position of a notice time indicating hand 6b is matched, for example, to a selected time designated to wake up. At the time of recording in an arbitrary voice, a mother records, for example, 'it is time' toward a microphone 2 in the state that a recording switch 8a is pressed, and when the switch 8a is released, the recording is finished. When it becomes the selected time, a reproduced state is started, and the recorded content is sounded from a speaker 4 together with the time notice. That is, the mother's voice is continued 'it is time, it is time' repeatedly reproduced without pause time. When the top of a reproduction release/stop switch 8c is pressed down, the reproducing is stopped. The volume at the time of reproducing can be altered by operating a volume set control 7b.
