Title: Infrared-ray thermometer
Inventor: AMANO SHIRO
IPC: G01J5/10
Filed: 1985-11-07
Abstract: PURPOSE:To surely measure the temperature distribution of plural objects to be measured,by not using an expensive lens but using infrared-ray sensors having wide angles of field. CONSTITUTION:Objects to be measured N1 and N2 are in the measuring visual field of an infrared-ray sensor S1 and the object N2 and an object to be mea sured N3 are in the measuring visual field of another infrared-ray sensor S2, and then, the object N3 is in the measuring visual field of the 3rd infrared-ray sensor N3. The infrared-ray sensors N1, N2, and N3 can make detection by making distinction among three states, no exothermic object, one exothermic object, and two exothermic objects. Various kinds of combination exist in the relation between the temperature states of the objects N1, N2, and N3 and output states of the infrared sensor S1, S2, and S3 when outputs of each sensors are '1', '2', and '3', but a temperature distribution discriminating means T can distinguish each of the combination from the combination of the outputs of the sensors S1-S3. Therefore, the temperature distribution of plural objects to be measured can be discriminated even when infrared sensors having wide angles of field are used without using any expensive lens.

Filed: 1993-10-05
Abstract: PURPOSE:To enhance accuracy in the measurement of moisture by drying the carrier gas using an electrolytically regenerative phosphorus pentoxide dehydrator thereby dehydrating the carrier gas reliably for a long term. CONSTITUTION:Phosphorus pentoxide(P2O5) absorbs water(H2O) to produce metaphosphoric acid(2HPO3) which returns back to phosphorus pentoxide through electrolysis upon application of voltage (2HPO3 H2+1/202+P2O5). When a flow rate of gas in the range of 100-500ml/min is required, two platinum wires and two copper wires having diameter in the range of 0.1-1mm are wound alternately around a copper pipe of 1.2-2.0mm. It is then inserted into a glass pipe and secured to the inner wall thereof by heating and then copper is dissolved into a nitric acid solution thus leaving only platinum. Two platinum wires, spaced apart from each other, are employed as anode 32 and cathode 33 which are fed with P2O2 solution and dried. A voltage of 5-90V is then applied to cause electrolysis for forming a thin film of P2O5 between the electrodes 32, 33 thus providing a regenerative dehydrator. This constitution allows easy removal of moisture from carrier gas for a long term.

Title: Printing device
Inventor: KISHINO YASUKAZU
IPC: B41J2/355
Filed: 1991-09-30
Abstract: PURPOSE:To prevent white lines fro being generated by doubly printing previous line data provided as long as prescribed conditions are satisfied when the data by one line are not present on a data buffer at the time of the generation of a synchronous signal. CONSTITUTION:At the time of the actuation of a printing operation, the synchronous signal is generated by the occurrence of the interruption of a synchronism timer. A line data detecting means detects whether or not the printing data by one line are present on the data buffer provided within a RAM 10. When the printing data by one line is not present on the buffer within the period of the synchronous signal, one hit of a rotation instruction pulse is generated only at timing corresponding to a first synchronous signal. Then the identical double printing means of a thermal head is actuated to transfer the previous line data to the thermal head 2 and perform double printing. This is performed based on the prescribed conditions at the time of the generation of the synchronous signal and thus, the generation of the white lines can apparently by prevented.
