Title: Printer
Inventor: ATSUMI YOSHIJI
IPC: B41J15/04
Filed: 1981-04-09
Abstract: PURPOSE:To prevent the damage of a continuous paper sheet and simultaneously to reduce a load on a tractor driving motor by adjusting a gap between paper feeding rollers when the sheet is fed back in a printer for which the continuous paper sheet is used. CONSTITUTION:When a continous paper sheet 2 is fed back in a prescribed amount to return the sheet to an initial state after completion of printing of a final line, an electromagnet 16 is excited to attract a supporting lever 13 made of a magnetic material against a spring 15. By this attraction, the continuous paper sheet 2 is fed back by a tractor 5 under the condition that a follower roller 12 is separated from a driving roller 11 and thus no tensile force is applied between the driving roller 11 and the tractor 5. Therefore, the damage of a perforation and the like are prevented and no excessive load is applied to a tractor driving motor.

Title: Impeder for tube manufacture welding
Inventor: HAYASHI TOMOTAKA
IPC: B23K13/08
Filed: 1990-03-05
Abstract: PURPOSE:To use the impeder for tube manufacture welding as an impeder core having the high service life by using a foil body made of amorphous metallic material or the whole surface of an extra fine wire subjected to insulation coating as a core. CONSTITUTION:Since a filmy amorphous alloy 10 or a wire-shaped amorphous alloy is subjected to insulation coating 11 on the whole surface for each simple substance thereof, its rustproofing performance is excellent. Accordingly, it is not necessary to add Cr to the amorphous alloy material 10 and a material design considering only magnetic characteristics is also made possible. Since the impeder for tube manufacture welding has high cooling power, even when load of high frequency is high, it can be used as the impeder core having the high service life without burning the amorphous alloy having satisfactory magnetic characteristics.

Title: Production of reaction-sintered ceramic
IPC: C04B35/58
Filed: 1992-03-13
Abstract: PURPOSE:To obtain a reaction-sintered ceramic with the shape of pore reduced by heating and sintering an amorphous metal oxide powder compact in the reactive gas reducing atmosphere contg. an oxide reducing gas. CONSTITUTION:A compact of an amorphous metal oxide powder is heated and sintered in the reactive gas atmosphere contg. an oxide reducing gas to obtain the object ceramic. Although the average diameter of the globular grains of the amorphous metal oxide is controlled to <=0.5mum or preferably to <=0.2mum, the oxide of <=20nm superfine grains is also used. The shape of pore in the reaction-sintered compact is reduced as the grain is decreased in size, the pores of the submicron or subnanometer order between the grains are uniformly distributed, and the mechanical strength is remarkably increased. The pore shape is reduced to <=0.1mum by using the superfine-grain amorphous metal oxide, and the strength is efficiently increased.

CONSTITUTION:Second heat generating resistors 5 are so arranged on the surface 2a of an insulating substrate 2 as to be superposed on a first heat generating resistor 4 over a glass glazed layer 3, and a common electrode 6 and individual electrodes 7 are formed. The electrode 6 is provided in contact with the edge 2b, the end 6a is superposed on the end 5a of the resistor 5, and the ends 7b of the electrodes 7 are superposed on the other ends 5b of the resistor 5.

In this case, since the center 8a of the area 8 is superposed with the resistors 4, 5, its area resistance is reduced from the end 8b of the area. Accordingly, the voltage drop of the end 8b is increased, and the quantity of heat generated in this part is increased, thereby obtaining substantially uniform temperature distribution in the area 8.

Filed: 1982-04-01
Abstract: PURPOSE:To improve the position and speed detecting accuracy of a vehicle by measuring the pulse interval of pulses from a position detector and removing as a noise the pulse having no normal pulse interval. CONSTITUTION:A filter 21 removes a pulse which has a pulse interval Tmax corresponding to the maximum speed of a vehicle at the position pulse interval.

Title: Concentration analysis method
Inventor: MABE SUGIO
IPC: G01N31/16
Filed: 1995-03-15
Abstract: PURPOSE: To enable highly accurate analysis of the concentration of a specified substance addressing emergency analysis quickly by performing a photometry of a reaction liquid at a plurality of specified reaction times separately to determine concentration values based on a plurality of photometric data and a corresponding calibration curve generated previously and further a true concentration value based on the plurality of concentration values. CONSTITUTION: Absorbance of a sample to be measured at reaction times TA and TB is analyzed in terms of reaction component and error component to determine a concentration value. The error component of the absorbance is determined based on the concentration value on condition that the absorbance of the reaction component is constant in ratio in terms of reaction time and the error component is uniform regardless of the reaction time. Then, the error component is corrected from any one of the absorbances measured to determine an absorbance attributed to reaction and a true concentration value is determined based on a calibration curve corresponding to the absorbance.  Thus, the error attributed to the fouling of a reaction container is corrected thereby always enabling analyzing of the concentration of a specified substance at a high accuracy and also addressing of a demand for emergency analysis quickly, eventually achieving higher processing efficiency.
