Ultrathin membranes for separating substances are obtained by exposing shaped articles comprising a water-soluble polymer or a mixture of a water-soluble polymer and water-insoluble polymer to a plasma of a gas selected from helium, argon, nitrogen, hydrogen, oxygen, carbon monoxide, carbon dioxide, ammonia, a hydrocarbon having 1 to 10 carbon atoms, an epoxide having 2 to 10 carbon atoms, or an alkylamine, or a mixture of these substances to crosslink the surface layer, and then washing the exposed articles with water to remove the unreacted portions. The membrane exhibits outstanding performance characteristics when used in the processes for separating or concentrating substances, such as reverse osmosis, ultrafiltration, and the like.

Paper feed mechanism of a printer is disclosed for exactly transmitting rotative force of a drive shaft which interlocks a drive mechanism to a sprocket wheel which is provided for feeding a printing paper without play, and for locating and detaining the sprocket wheel at a desired position by an easy operation.The above-said mechanism comprises a disc which is fixed to the sprocket wheel, a detaining knob which has a shaft hole for inserting the drive shaft and fitted rotatably to the disc via a pair of snap shafts, a C-shaped spring, one end of which is fixed to the disc, the other end to the detaining knob, for turning each of them conversely.By these provisions, the inner circumference of the shaft hole which is provided at the center of the detaining knob comes into close contact with the drive shaft by the spreading force of the above-said C-shaped spring, therefore, the play between the shaft hole and the drive shaft is excluded to feed the printing paper exactly by the sprocket wheel and an improved printing quality can be obtained. Further to that, the sprocket wheel can easily be detained at desired position by turning the detaining knob against the force of the C-shaped spring.

The present technique relates to an image processing device and method capable of performing an encoding process or a decoding process on an image at high speed. Similarly, arithmetic coding parameters arranged together in the syntax are subjected to a variable length (fixed length) decoding process together. Similarly, arithmetic coding parameters arranged together in the syntax are subjected to an arithmetic decoding process together. Accordingly, since the alternations of firmware and hardware are performed together, it is possible to improve the processing efficiency of decoding. As a result, it is possible to perform the process at high speed. The present disclosure can be applied to image processing devices, for example.
摘要:
In a frictional drive vehicle, a load acting on the vehicle such as the weight of a rider is converted into a force that urges two frictionally engaging parts (3L, 3R, 25) toward each other. Thereby, the contact pressure between the two frictionally engaging parts is maintained at an optimum level under all conditions. A weight of a rider may be transmitted to a drive member that frictionally engages a main wheel via a four-link parallel link mechanism (40, 50).

Development efficiency and mass production efficiency of a semiconductor chip (LSI) is improved, whereby the LSI on which an integrated circuit is formed has plural pad parts connecting the integrated circuit with an external circuit. The pad part is provided with a first junction consisting of a window formed in the protective film and the pad exposed from the window, and a second junction consisting of a window formed in the protective film and a bump deposited on the pad exposed from the window. When it is required that the LSI is to be connected with an external circuit by wire bonding, the first junction is connected with the external circuit using a wire. When it is required to connect the LSI with an external circuit by the TAB method or the COG method, the second junction is directly connected to the external circuit.

In an editing apparatus, the work efficiency can be improved comparing to a conventional apparatus. Storage means (14) having a plurality of input ports and at least one output port; and control means (16) for controlling the recording areas of the storage means, in which the different recording area is respectively assigned to each of a plurality of encoding means (11 to 13) as a recording area in which the encoded data is stored, the recording area in which the encoded data has been stored is assigned to the multiplexing unit (15), and the recording area which is different from that of the encoded data is assigned as the recording area in which the multiplexed data is stored are provided, so that the storage means can be commonly used both in the encoding means and the multiplexing means. Thereby, the data transfer between encoding means and the multiplexing means does not performed. Therefore, the editing apparatus (10) which improves the work efficiency comparing to the convention apparatus can be realized.
