摘要:
An apparatus for automatically cleaning surfaces of an application apparatus is disclosed. The invention is characterized in that it includes a basement extending in parallel with the longitudinal direction of an application apparatus used to apply a magnetic dispersion liquid to a flexible carrier, a tracer movable on the basement, a traverser which can be moved from the tracer to a position over the edge surfaces of the application apparatus and be moved vertically relative to the surfaces, and a cleaning head coupled to the traverser at the end portion thereof so that the head can be placed in elastic contact with the edge surfaces.

A multichannel record disc reproducing apparatus has a pickup cartridge for picking up signals from a multichannel record disc. A multiplexed signal was recorded on the disc by first multiplexing direct wave signals and angle-modulated wave signals which are recorded on opposite groove walls. Filters separate the picked up multiplexed signal into the direct wave signal and the angle-modulated wave signal. A demodulates circuit for demodulating the angle-modulated wave signal, thus separated. A matrix circuit separates the signals to obtain a plurality of separate channels from the direct wave signals and the demodulated signals. A circuit in a stage preceding the demodulator removes substantially all components of the higher harmonics at the carrier wave center frequency, which carrier was used for angle-modulating the original signal.

A flow rate control mechanism for use in controlling the flow rate of exhaust gases in an exhaust gas re-circulating system of an internal combustion engine. This mechanism includes a swirl flow chamber having a circular cross section, a first nozzle and a second nozzle, the former of which is open through the inner wall of the swirl flow chamber therein in the direction normal thereto and the latter of which is open through inner wall of the swirl flow chamber therein in the direction tangential thereto. The latter nozzle is positioned close to the opening of the former or first nozzle. The first nozzle directed in the normal direction extracts part of exhaust gases through an exhaust manifold, while the second nozzle directed in the tangential direction is communicated with atmosphere. The opening of the first nozzle is close to the opening of the second nozzle, so that the pressure at the opening of the first nozzle approximates the atmospheric pressure. As a result, the flow rate of exhaust gases which having been extracted through the exhaust manifold and fed into the flow rate control mechanism will be proportional to the square root of the exhaust gas pressure. On the other hand, the flow rate of intake air will be proportional to the square root of the exhaust gas pressure. Thus, the exhaust gases at a flow rate proportional to that of intake air is introduced into the swirl flow chamber, so that the both gases are mixed therein and fed into an intake manifold.

An improved air flow direction control valve particularly adapted for use with an exhaust gas purifying system on an internal combustion engine to control the direction of flow of air to be mixed into exhaust gas for effecting additional combustion of the uncombusted constituents therein. The valve essentially comprises a pair of valve members selectively operable to open one of two main outlets and a diaphragm operated shaft for selectively operating the two valve members upon movement between a first and a second position. The shaft is formed with a pair of shoulders which define a reduced diameter shaft portion therebetween, and the two valve members encircle the reduced diameter shaft portion in an oppositely facing relation. The reduced diameter shaft portion is slidable relative to the two valve members and upon movement of the shaft axially into its first position, one of the shoulders thereof is engageable with the first valve member to open the first main outlet, while the other shoulder is engageable with the second valve member to open the second main outlet upon movement of the shaft into its second position. At least one coil spring is provided for urging either of the valve members not engaged by the corresponding shaft shoulder, into a position to keep the corresponding valve outlet closed. The valve further includes a third valve member which is resiliently supported to close an auxiliary valve outlet. According to one embodiment of the invention, the third valve member is operated independently of the shaft, while according to another embodiment, it is operationally associated with the shaft.

An indicator of vehicle service intervals for use in a vehicle comprising a transducer for transducing the revolution of the transmission output shaft of the vehicle into an electrical signal, an electrolytic integrating element electrolytically corroded by the output signal of the transducer, and a display unit for giving visible and audible alarms in response to the circuit cut-off action of the time limit element. In the system, successive pulses representing the distance traveled by the vehicle are integrated to cause progressive electrolytic corrosion of the electrolytic integrating element, and the alarm is displayed when the total traveled distance attains a predetermined value.

A pattern film forming method includes a step of producing a transfer sheet in which a thin film is formed on a surface of a sheet-shaped material and a step of pressing the thin film against a pattern film formation surface of the substrate with a pressing member having convex portions corresponding to the pattern film from a reverse surface of the transfer sheet opposite to the thin film or a reverse surface of the substrate opposite to the pattern film formation surface to transfer the thin film to the substrate. A pattern film forming apparatus includes a sheet supply device, a pressing device and a substrate transport device. A high-definition pattern film having a desired pattern and a sharp edge can be formed with high productivity.

A coating apparatus (10) has a coating head having a front edge surface (11) and a doctor edge surface (12). The coating head of the coating apparatus (10) is pressed onto a flexible support (100) laid and running between pass rollers (101) so that the support (100) can be coated with coating composition. The doctor edge surface (12) of the coating apparatus (10) is formed so that the variation rate, in the support width direction, of blade thickness in the support running direction of the doctor edge surface (12) does not exceed 5%.

A method and apparatus for removing dust from a base film effectively so that electrostatic charges of the base film are reduced while the cleaning effect is kept high. After a cleaning solvent is applied onto one surface of a base film by a precoater, a rod member is pressed against the base film while the cleaning solvent remains on the base film, so that deposits on the base film are separated and scraped together with the cleaning solvent from the base film by the rod member. Just after the deposits are scraped from the base member, a solvent, of the same kind as the cleaning solvent or a mixture of a solvent of the same kind as the cleaning solvent and an additive mixed thereto, is applied onto the base film while the surface of the base film coated with the cleaning solvent is not exposed to an atmospheric air space.
