A data compression system is provided having a fixed length coding unit provided before a universal coding unit. The fixed length coding unit detects mode classifications and mode conditions of changing picture elements in a mode detecting unit. Then, the mode classifications and mode conditions are converted to fixed length code words in a code transforming unit representative of, e.g., MH, MR or MMR-type codes. Thereafter, the fixed length code words are predictively coded by the universal coding unit to output compressed data. The present invention is applicable to both character data and picture data. Preferably, the picture data is preprocessed by the fixed length coding unit before both of the character data and picture data are predictively coded by the universal coding unit.

A method for winding a continuous fabric on a cylinder together with a wrapping cloth in which, as a preparatory step for carrying out the decatizing treatment of fabric, a press roller always urges the surface layer of the rolled fabric toward the axis of the cylinder, during the winding operation. The contact pressure of the press roller is gradually increased under a controlled condition so that the binding force created by an outer layer of fabric toward an adjacently inner layer of fabric can be maintained in a substantially uniform condition. To increase the contact pressure of the press roller, a pressure control device is applied to the winding apparatus.

Disclosed is an intake air volume measuring device for an internal combustion engine. The device includes an air flow meter located in an intake air path of the internal combustion engine, to measure the volume of intake air into the combustion chamber of the internal combustion engine based on an output signal of the air flow meter. The output signal of the air flow meter (AFM signal) is sampled in synchronism with the crank angle of the internal combustion engine. With this angle-synchronous processing, the device is capable of obtaining AFM data at equal intervals within a cycle of intake air pulsation, thereby eliminating adverse effects of the intake air pulsation. The device is hence capable of reducing variations in AFM data averages and calculating average flow rates of the intake air with high precision.

An electrolyte membrane for solid polymer fuel cell includes a reinforce membrane made of nonwoven fibers and an electrolyte provided in a space among the nonwoven fibers. The nonwoven fibers have a non-uniform mass distribution in a plane of the electrolyte membrane. A mass of the nonwoven fibers per unit area in a region corresponding to at least part of a peripheral portion of a fuel cell-use gasket frame is greater than a mass of the nonwoven fibers per unit area in a region corresponding to a center portion of the gasket frame. The electrolyte membrane for solid polymer fuel cell is attached to the fuel cell-use gasket frame.

By irradiating laser light 20 obliquely onto a substrate 6, the laser soldering apparatus reduces the laser light passing through an insertion hole 61a in the substrate 6 and prevents damage to low-heat-resistance portions of a component 62 disposed on the rear surface side of the substrate 6. Moreover, the substrate 6 can be observed from a normal direction with a camera 23. Therefore, even if the insertion hole 61 for inserting a component lead or the like is provided in the substrate 6, the laser light does not leak out to the side of a component mounting surface 17 of the substrate 6.

The invention is a method for pulling a silicon single crystal, which is a Czochralski method for growing the silicon single crystal by contacting a seed crystal with a melt and by pulling up, including the steps of: contacting the seed crystal with the melt; forming a necking portion under the seed crystal; and forming the silicon single crystal under the necking portion by increasing a diameter, wherein a pulling rate during forming the necking portion is 2 mm/min or less, and the silicon single crystal with the increased diameter is a boron-doped silicon single crystal having a resistivity of 1.5 mΩ·cm or less at a shoulder portion. Therefore, there can be provided a method of pulling a silicon single crystal without generating defects such as scratches at a wafer surface in the case of processing a boron-doped silicon single crystal ingot with a low resistivity produced by CZ method into a wafer.
