Abstract: PURPOSE:To inexpensively produce a halofluoro compound useful as a precursor of fluoroalkene in good position selectivity by treating an alkene with a dihydrogenated trifluorinated quaternary ammonium together with a halonium ion generating agent. CONSTITUTION:A compound shown by formula II (R<1> to R<4> are H, alkyl or aryl) is treated with a compound (e.g. dihydrotrifluorotetramethylammonium) shown by formula I (R<a> to R<d> are alkyl) together with a halonium ion generating agent (e.g. N-bromosuccinimide) to produce a compound shown by formula III (X is I or Br). The amount of the compound shown by formula I and that of the halonium ion generating agent used are preferably 1-3 equivalent and the reaction temperature is suitably 0-25 deg.C. The reaction may be carried out in a solvent such as hexane, benzene, THF, etc. Haloflurinattion of an alkene having a functional group weak to an acid is also advanced without problems.

Title: Electromagnetic measuring device
Inventor: SUZUKI YOSHINORI
IPC: G01S3/22
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To accurately measure the strength and arrival direction of a received electromagnetic wave at high speed by separately amplifying and detecting each output of two loop antennas being orthogonally crossed for arranging, and synthetic output of both the antennas. SOLUTION: The output of a north and south antenna 1ns of a loop antenna system 1 being orthogonally crossed is divided into two by a distributor 22ns, and one output is supplied to a receiver 3ns. Similarly, the output of an east and west antenna 1ew is divided by a distributor 22ew, and one output is supplied to a receiver 3ew. The other output being divided by the distributors 22ns and 22ew is synthesized by a synthesizer 22t for supplying to a receiver 3t. Although the receivers 3ns, 3ew, and 3t amplify and detect each output, an automatic gain control voltage at this time is changed according to a reception level. A/D converters 4ns, 4ew, and 4t convert the AGC voltage into a digital value. A computer 5 calculates the strength and arrival direction of an electromagnetic wave according to the square sum of the digital value or the like.

IPC: G11B15/467
Filed: 1988-08-09
Abstract: PURPOSE:To realize the optimum tracking condition even in the case of existence of programs recorded by plural equipments on the same cassette tape by storing a set value relating to the max. value of an envelope, detecting the envelope even after completing a tracking adjustment and comparing it with the set value. CONSTITUTION:Outputs of rotary heads 1 and 2 are turned into one system signal by a head switching circuit 4 to be inputted in an envelope detecting circuit 5. The envelope of a reproducing output is extracted by the detecting circuit 5. In this case, a tracking delay amt. is decided in order to make the envelope of a regenerative signal max., and at this time, a K-fold (K<1) value as much as the max. value is stored. When the envelope once becomes mas., the tracking adjustment operation is completed, but a comparison is made between the envelope and the set value, and when the envelope becomes smaller than the set value, the tracking adjustment operation is then resumed. In such a manner, even when plural programs are recorded on the same cassette tape, the optimum tracking condition can always be realized.

Title: Manufacture of chip resistor
Inventor: SASAKI YUKITOSHI
IPC: H01C17/24
Filed: 1987-08-07
Abstract: PURPOSE:To make a path of an electric current in a resistor long and to reduce a noise of the resistor by a method wherein a part between electrodes divided by a slit is formed in such a way that the part is interconnected in a zigzag manner. CONSTITUTION:A nearly square or rectangular thick-film resistor 11 is formed on a substrate; then, one pair of electrodes 12, 13 are formed at both ends of the resistor 11. Slits 11a-11c are formed in the resistor 11 by a trimming operation by using a laser machining process; after that, the surface of the resistor 11 is covered with a protective film. At this stage, because no electric current flows to the slits 11a-11c, a path of an electric current in the resistor 11 is made long due to the slits 11a-11c and the path where the electric current flows in the resistor 11 between the electrodes 12, 13 is made long. By this setup, it is possible to remarkably improve a noise characteristic of a chip resistor.
