A manufacturing method of a negative electrode for a non-aqueous electrolyte rechargeable battery has a primary kneading step and a secondary kneading step. In the primary kneading step, conductive material, polymer, and a dispersion medium are mixed and primarily kneaded. The conductive material contains at least fibrous carbon of which aspect ratio is at least 10 and at most 10000. In the secondary kneading step after the primary kneading step, active material capable of storing and emitting a lithium ion and another portion of the dispersion medium are added, and secondary kneading is performed. The active material contains at least silicon.

An electromagnetic flow meter for industries includes a transducer and a signal processor provided separately from the transducer. The transducer having an exciting circuit, an amplifying and calculating part and a transmitting part outputs an analog flow rate signal and digital signals which are superimposed to the an analog flow rate signal to the signal processor. The analog signal sent to the signal processor is passed through the signal processor without receiving any signal processing and the digital signals are sent into the transducer or taken into the signal processor through alternating current coupling means. The data transmission is diagnosed by checking the conformity between the data stored in the signal sending part and the received data. Data set in a data setting part provided in the signal processor are sent to the transducer through a transmitting cable in which the flow rate data are also transmitted.

An electromagnetic flow meter comprises a ceramic measuring pipe formed into a straight cylinder through which fluid to be measured flows, electromagnetic field generating device disposed adjacent to a central portion of an outer surface of the central portion of the ceramic measuring pipe for generating an electromagnetic field into a radial direction of the ceramic measuring pipe, electrodes for detecting an electric potential generated in the fluid, a case which accommodates the ceramic measuring pipe, the electromagnetic field generating device and the electrodes, and sealing members which are disposed between inner surfaces of the flanges of the case and ends of outer circumference of the ceramic measuring pipe. The case has a length longer than that of the ceramic measuring pipe and flanges at both ends thereof. Inner diameters of the flanges are slightly larger than an outer diameter of the ceramic measuring pipe. Portions of the sealing members outwardly project over the end surfaces of the flanges of the case.

摘要:
An air cleaning machine to be used in houses, offices and so on utilizes an ultraviolet-ray sensor and a gas sensor jointly to combine the characteristics, so that the operation of the appliance becomes extremely smooth. The appliance operates almost immediately especially when a signal from a light is received. If a cigarette is lighted, for example, indoors, the air cleaning machine operates immediately to clean the air, so that the user may actually feel it. When the gas occurs even under the circumstance where the ultraviolet ray does not reach the light sensor, the normal operation is performed, thus allowing the automatic operation to be effected. Accordingly, clean air is normally provided under the optimum circumstance.
摘要:
A foam bathing apparatus comprising a main body including a blower, a container mounted on the main body for containing a bath and a porous body disposed at an inner bottom portion of the container. Air from the blower is passed through the porous body to produce numerous air bubbles in the bath for the user to immerse the face or the like in the bath for cleansing or massaging. The apparatus includes a pressure chamber provided within the main body and positioned downstream from the blower in proximity thereto, the pressure chamber being provided with a pressure adjusting assembly comprising, for example, a pressure adjusting aperture and a shutter for opening or closing the aperture for smooth and fine adjustment of the amount of air bubbles to be produced. The apparatus is usable also for cleansing or massaging other part of the human body, such as the hand, elbow or foot.
