Title: Production of substituted olefin
Inventor: TOKUNAGA YUKO
IPC: B01J31/24
Filed: 1989-03-08
Abstract: PURPOSE:To directly obtain the title substance by reacting a raw material compound having C-H bond with acetylenes in the presence of a transition metal complex such as Rh, Ir or Co in mild conditions while irradiating light. CONSTITUTION:(A) A compound (e.g. benzene, furan, methane, cyclohexane, propylene or ethyl acetate) having C-H bond (sigma bond) is reacted with (B) acetylenes in a molar ratio of 30-600 in the presence of a transition metal complex (of <=1/200 molar ratio based on the ingredient B) at 0-150 deg.C while irradiating light to provide the title substance. As the transition metal ingredient, Ir or Co or especially Rh is preferably used. Specific example of ligand includes trimethylphosphine. Though a solvent is not especially required by using a large excess of the ingredient A, as necessary perfluoroalkane, etc., can be used.

Patent JP-S63221471-A (JP)
Title: Japanese word processor
Inventor: TANBARA MASAO
IPC: G06F17/22
Filed: 1987-03-11
Abstract: PURPOSE:To eliminate input troublesomeness by registering a word having one head KANA (Japanese syllabary) character of the highest using frequency in a memory and displaying and selecting the registered word via a key input. CONSTITUTION:When a conversion key is pushed after a conversion start key and then a key corresponding to the reading of a word, a controller 2 accesses a registering memory 5 to check the presence or absence of registered words. If the registered words are confirmed, a word having the highest using frequency is displayed on a display. If no registered word is confirmed, the controller 2 accesses a word memory 4 containing a frequency learning function to display a word having the highest using frequency on the display 3 among those reading types. If no word desired by a user is offered, the next candidate is selected via a keyboard 1 and the display 3. The controller 2 compares the using frequencies with each other for the words registered in one desired head KANA character stored in an automatically registered word memory 6 for single head KANA character reading. Then the controller 2 replaces the contents of the memory 6 with the word having the highest using frequency and outputs a list. The relevant word is displayed with operation of a key.

Title: Deflection yoke
Inventor: HOSOI YUICHI
IPC: H01J29/76
Filed: 1991-01-31
Abstract: PURPOSE:To prevent generation of vertical striation due to difference in the brightness produced locally on the screen, even though the horizontally deflecting frequency is turned into high frequency, by connecting the wind start part of each coil fragment located on one side of the vertical axis with the wind end part of another coil fragment which is located at the other end of the vertical axis. CONSTITUTION:A pair of troidal type vertically deflecting coils 21V are wound on a ferrite core 22 and diverge parallelly to one terminal 23a positioned in the vertical axis direction. The coil 21V is composed of upper coils 24U, 25U wound in the same direction and lower coils 24D, 25D wound oppositely to the coils 24U, 25 with time horizontal axis as the boundary and arranged parallelly while the other terminal 23b side positioned in the vertical axis direction is used as wind end part. Because the mutual inductance of the coils 24U, 25U and the ones 24D, 25D is negative according to this constitution, the vertical striation due to difference in the brightness to be generated locally on the screen can be reduced to a degree not distinguishable visually.

IPC: C25B1/00
Filed: 1987-03-13
Abstract: PURPOSE:To produce a Ce(NO3)4 soln. having comparatively high concn. at high current efficiency, by using a nitric acid soln. contg. Ce(NO3)3 as an anolyte and an electrolyte uncontaining NO3<-> as a catholyte and a cation exchange membrane as a diaphragm, and performing electrolytic oxidation. CONSTITUTION:In the case of obtaining a soln. contg. Ce(NO3)4 by subjecting the soln. contg. Ce(NO3)3 to electrolytic oxidation, a nitric acid soln. contg. Ce(NO3)3 is used as an anolyte. On the other hand, an electrolyte such as sulfuric acid uncontaining NO3<-> is used as a catholyte and thereby formation and accumulation of NH4<+> resulting from reduction are prevented. Further a cation exchange membrane is used as a diaphragm and diffusion of a ion is prevented. As this exchange membrane, a fluorine-base ion exchange membrane good in durability is more preferable. Furthermore as an electrode, an anode such as titanium coated with iridium oxide and a cathode such as stainless steel are used and electrolysis is performed at about 1-70A/dm<2> current density at the temp. not more than about 150 deg.C. Thereby the nitric acid soln. of Ce(NO3)4 uncontaining NH4<-> is obtained with high efficiency.

Title: Scanning type electron microscope
Inventor: NAKASUJI MAMORU
IPC: H01J37/244
Filed: 1989-03-09
Abstract: PURPOSE:To make it possible to observe a good image of a sample with resolution faithful to an electron beam spot by installing a secondary electron detector in a gas sealing chamber distant from a position to be irradiated with an electron beam more than the operational distance of an objective lens, and surrounding the secondary electron detector by a secondary electron reflection member. CONSTITUTION:An electron beam locus 4 is deflected by deflectors 10 and 11, and passes through an opening of a pressure restriction member 9 so as to scans a sample target 12. Secondary electrons emitted out of the target 12 repulsively move to a secondary electron detector 6 due to a negative voltage applied to the pressure restriction member 9. The secondary electron collide with gas on their way to increase their number. The secondary electrons are therefore incident to the positively charge electrode of the 6 without being trapped by a secondary electron reflection electrode 7 and a reflected electron shielding electrode 8 having negative potential 8. The electrode of the detector 6 is made of Be and is formed in wedge-shaped on its surface so that distributed noise due to re-reflected electrons, etc., is rarely produced when the secondary electrons are incident thereto.

Filed: 1983-04-01
Abstract: PURPOSE:To attain ease of control by adding separate simple hardware as a means disconnecting a talking path to a 4-wire exchange exchanging a highway for transmission signal and a highway for receiving signal by means of a highway switch. CONSTITUTION:A transmission signal is digitized by an A/D converting circuit and a digitized receiving signal is converted into an analog signal by a D/A converting circuit. AND gate circuits 9, 10 gate an input signal to the D/A converting circuit by a command of a scan processor 3. The talking of received voice is blocked by adding the receiving gates 9, 10 under the control of a scan processor 3, without expecting the disconnection of the dial tone (e.g., DT) required for high speed control by the switching of a highway switch 8 in the operating process of telephone exchange. Thus, a CPU 4 controls the switch 8 according to the substantial operating method so as to eliminate the DT tone.
