Title: Production of fluorinated pyridines
Inventor: KUMAI SEISAKU
IPC: C07D213/61
Filed: 1993-04-16
Abstract: PURPOSE:To efficiently and safely obtain fluorinated pyridines under industrially advantageous conditions at a high rate of reaction by fluorinating halogenated pyridines with a fluorinating agent in the presence of a tertiary amine. CONSTITUTION:Halogenated pyridines expressed by formula l {X is Cl, Br or I; R is alkyl or fluorinated alkyl; k is 1-5; m is 1-5; n is 0 or 1; k is >=m; [k+m+n] is <=5} are fluorinated with a fluorinating agent (especially an alkali metallic fluoride such as KF) in the presence of a tertiary amine such as triethylamine or tri-n-propylamine to afford fluorinated pyridines expressed by formula II (e.g. 2-fluoropyridine). A fluorinating catalyst such as tetramethylammonium chloride is preferably further used in this reaction. It is important to carry out the fluorinating reaction in the presence of the tertiary amine for the reaction. Thereby, the production of fluorine can be suppressed and this method is a safe one for the working environment. The resultant compounds are useful as an intermediate for medicines, agrichemicals and functional substances such as a liquid crystal.

Title: Receiving channel scanning method
Inventor: KINOSHITA KATSUMI
IPC: H04B1/16
Filed: 1993-04-19
Abstract: PURPOSE:To decrease the number of times of setting of a received frequency even when a receiver is not provided with a receiving part of two system or a first local oscillator by sweeping the frequency of a pair of selected receiving channels, and selecting the pertinent receiving channels. CONSTITUTION:Two adjacent receiving channels are combined, and divided into pairs G1, G2,... Gm so that there is no overlapped receiving channel between each pair. At the time of starting the scanning of the received frequency, a CPU 42 outputs channel setting data through an output circuit 44 to a phase comparator 32 of a first local oscillator 3 so that a first local oscillation signal for allowing a receiving part 1 to receive a frequency fG1 between two receiving channels (f)1 and (f)2 of the pair G1 can be generated, receives data obtained by digitalizing by an A/D converter 41 a received electric field strength signal outputted from a demodulator 17 of the receiving part 1 and stores the data in a memory 43. This processing is repeated until the end of the processing of the final pair Gm is detected. When it is detected, the CPU 42 refers to the data stored in the memory 43, and selects two data whose received electric field strength value is larger as the pair pertinent to a condition.

Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To obtain a high-quality image record with a simple constitution, less number of parts and a high precision in positioning of a thermal head to a platen roller. SOLUTION: A conventional bracket includes three parts: left and right side plates with positioning parts 9 and a bracket central part with a fulcrum 10, and a new bracket 13 has those three parts integrally formed into one piece. In addition, a thermal head 1 is fixed at a point in the middle of the bracket 13 by a set screw 14. Thereby, such a trouble that the thermal head 1 is distorted due to the difference in thermal expansivity between an aluminum heat sink of the thermal head 1 and the sheet metal of the bracket 13 (galvanized steel plate) and comes unevenly in contact with a platen roller is avoided. As the bracket 13 is one-piece part, the mounting precision of the thermal head 1 to the positioning parts 9 of the left and right side plates of the bracket 13 is improved. Therefore, a high-quality image record can be obtained with a simple constitution and less number of parts.

Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain an Al alloy conductor stably having good electrical connectivity even in an environment at high temp. and high humidity by forming a Zn coating in a specified thickness by a zinc displacement method on at least the electrical connection surface of an Al alloy substrate and further forming a chemical coating on the Zn coating. SOLUTION: The thickness of the Zn coating is 10-20 mg/m<2> . The Zn coating has low contact resistance and the adhesion between the Zn coating and the Al alloy substrate is improved because the oxidized coating of the substrate is removed by the zinc displacement method. The zinc displacement method is a method by which the Al alloy substrate is immersed in a highly alkaline sodium zincate bath and plated with zinc by displacement. The chemical coating formed on the Zn coating inhibits the surface oxidation of the Zn coating and ensures good electrical connectivity. The chemical coating is preferably a chromate, phosphochromate or zirconate coating. The Zn coating 2 is formed on the entire top of the Al allay substrate 1 or both the entire top and under surface and the chemical coating 3 is further formed on the Zn coating 2.

Title: Laser device, its operation method and application
Inventor: NAGAISHI RYUKI
IPC: H01S3/10
Filed: 1993-04-19
Abstract: PURPOSE:To maintain the laser light output and a laser beam shape fixed by providing an attenuator arranged on an optical path of laser light while allowing optional attenuation of laser light strength. CONSTITUTION:Laser light generated by an eximer laser is attenuated by an attenuator 2 for being reflected by a half mirror 7 while partly transmitting it to be incident on a sensor 3. Laser light reflected by the half mirror is focused by a focusing lens 9 for being irradiated on a target 16 inside a chamber 10. The sensor 3 detects strength of laser light transmitted the half mirror. When the strength of the laser light detected by the sensor 3 is changed, a microcomputor 4 outputts a control signal controlling an attenuating factor of the attenuator into the direction for negating the change. Thereby, a laser device causing no change of the strength of the laser light and the beam shape and its operation method, even if a long, continuous or intermittent operation is performed, can be obtained.
