Filed: 1978-11-27
Abstract: PURPOSE:To improve the transmissibility of an optical fiber in a long wavelength zone and the productivity thereof by specifying the refractive indexes and compsns. of the core, clad and support layer of the fiber. CONSTITUTION:P2O5-SiO2, GeO2-SiO2 or P2O5-GeO2-SiO2 type vapor phase raw material for clad 2 is deposited in the form of soot on the inside of a quartz glass tube for support layer 3, and the same kind of vapor phase raw material for core 1 is further deposited in the form of soot. This tube is heat treated to vitrify the soots, and the hollow portion of the tube is eliminated to form a preform rod, which is then drawn into an optical fiber of a desired diameter while being heated at a high temp. The refractive index distribution of core 1 of the fiber is of a convergent type having max. refractive index n0, and equation n0>n1>n2 is satisfied with respect to refractive index n1 of clad 2 and refractive index n2 of layer 3, thereby resulting in an optical fiber of a sufficiently wide zone.

IPC: B01J29/40
Filed: 1994-06-07
Abstract: PURPOSE:To efficiently remove a malodorous component from malodorous gas at room temp. regardless of the kind thereof by arranging a catalyst bed converting mercaptan to alkyl disulfide on the upstream side in a malodorous gas flow direction and arranging a catalyst bed removing alkyl disulfide, alkyl sulfide and alkylamine on the downstream side. CONSTITUTION:A catalyst obtained by supporting Ag on Y-type zeolite or the like can remove alkyl disulfide. This Ag catalyst is deteriorated within a short period with respect to mercaptan being an acidic component but does not come into contact with mercaptan directly by arranging a catalyst bed 2 converting mercaptan to alkyl disulfide on the upstream side and the capacity thereof is not deteriorated over a long period of time. Further, the Ag catalyst has excellent removing capacity even with respect to other neutral and basic malodorous components, for example, methyl sulfide. Therefore, by arranging the catalyst bed 2 converting mercaptan to alkyl disulfide on the upstream side and a catalyst 3 removing alkyl disulfide or the like on the downstream side, all of malodorous components are removed from malodorous gas.

Title: Instruction identification processing system using more than two types of codes of executing state routine
Inventor: FUJIMAKI MIDORI
IPC: G06F9/30
Filed: 1987-06-12
Abstract: PURPOSE:To simplify a program by converting an instruction under the procedure of an executing state routine into an adaptive code instruction in case the conversion is needed for an instruction code as the pre-processing of the executing state routine. CONSTITUTION:A code identification means 1 inputs the code identification information (not shown in a diagram) to decide whether the code identification information is equal to a JIS character code or an EBSDIC KATAKANA (square form of Japanese syllabary). Then the control is shifted to a code-based instruction conversion means 2 after said identification information is decided as a JIS character code or the KATAKANA code. While it is decided to perform no conversion of an instruction code and the control is shifted to an executing state routine procedure main body 3 when it is confirmed that the identification information in not equal to the JIS character code nor KATAKANA code. The means 2 selects the instructions adaptive to each code out of a code-based instruction code group 4 and converts an area which requires the different instructions according to codes within the main body 3. Thus it is possible to avoid the application of a branch instruction with the main body 3.

Title: Space heater
Inventor: YOKOYAMA MASASHI
IPC: F24D7/00
Filed: 1988-06-14
Abstract: PURPOSE:To perform defrosting without switching an operating state and to improve space heating capacity in the case of low atmospheric temperature by generating hot water by utilizing waste heat of a heat engine, and feeding it to a hot water tube provided before a refrigerant tube with respect to the flowing direction of the atmospheric air of a heat exchanger. CONSTITUTION:When an air conditioner is operated as room heating with power supplied from a generator 10 driven by a heat engine 11, hot water fed in a hot water tube 32 of hot water fed from a hot water generator 20 for generating hot water by the waste heat of the engine 11 dissipates heat of the atmospheric air introduced into a heat exchanger 3 to lower its temperature, and is circulated to the generator 20 through a tube 19. Since a refrigerant tube 30 of the exchanger 3 is disposed at the rear of the tube 32 with respect to the atmospheric air flowing direction, it is fed through refrigerant and the tube 32 even in winter to generate sufficient temperature difference from the atmosphere in contact therewith, thereby maintaining high space heating capacity. Further, if the tube 30 is frosted, a flow rate regulating valve 18 is fully opened, a large quantity of hot water is fed to the tube 32 to sufficiently heat the air introduced to the exchanger 3 in contact with the tube 30, thereby removing its frost.

Title: Flip-flop circuit
Inventor: NAITO MITSUGI
IPC: G06F11/267
Filed: 1990-06-06
Abstract: PURPOSE:To detect the fault of an asynchronous system input circuit by composing the circuit of a combining circuit and plural flip-flop circuits serially connected to constitute a scan circuit for scanning a relevant combining circuit connected to this combining circuit. CONSTITUTION:When testing a scan operation, by supplying a signal at an 'H' level, for example, to supply terminals 25-1 and 25-2 of a test control signal, the operation as a shift register is attained by the operation of an OR circuit regardless of a signal supplied to a preset terminal 23 or a clear terminal 24. Next, when a signal at an 'L' level is supplied to the terminal of the test control signal, the signal is fetched only to a master latch part 21. Afterwards, the 'H' level is applied again and shifted to the rear step of the flip-flop. When a data fetched in advance is shifted, it can be decided that the flip-flop is fetched and that there is no abnormality in the shift operation at all, namely, that there is no fault in the asynchronous system signal circuit.
