摘要： The object of this invention is to improve the safety of an engine by preventing fuel which might splash out of the fuel inlet on top of the fuel tank or drip onto the tank during fueling from coming in contact with the hot cylinder or any electrical components. Another object of this invention is to prevent vibration of the fuel tank and the noise which such vibration would cause. The fuel tank according to this invention has an upper and a lower portions joined by a flange, both of which are made from a resin material. The upper portion has a trapezoidal depression in its center which surrounds the fuel inlet and slopes downward toward one side of the tank. The overall surface of the upper portion is convex and also slopes downward toward the same side of the tank. A number of grooves on either side of the central depression run in the same direction and open onto the same side of the tank. The two halves of the tank are welded at the web of a ribbed flange which extends around the entire periphery.

摘要： There is provided an air guide casing for an air-cooled engine, characterized in that in an air-cooled engine, the air guide casing comprises an air guide member (11) (12) consisting of a synthetic resin molded product, which is fixed so as to connect with an inside air guide casing (30), an outside air guide casing (6) provided on the outside of the air guide member (11) (12) so as to cover the air guide member, and positioning means (13) for positioning the air guide member (11) (12) with respect to a cylinder block (2); the air guide member (11) (12) is positioned with respect to the cylinder block (2) through the positioning means (13); and the air guide member is fixed by holding and pressing at least one place of the air guide member (11) (12) between the tightening portion of the outside air guide casing (6) and the cylinder block (2). By minimizing the use of a sheet metal member, vibrations of the air guide casing including a fan cover is reduced, and noises produced by the resonance with engine vibration or other causes are prevented. Also, the number of bolts used and the working man-hour for welding etc. are decreased to achieve a cost reduction, and moreover the weight is reduced. Further, a gap developing at the attaching portion where the air guide casing is attached to a cylinder block is eliminated, by which the leakage of cooling air and the amplification of vibrations due to the gap are prevented.

摘要： A composite finite impulse response digital filter for use in an image processing apparatus or the like includes a plurality of sub-filters connected in series. In each sub-filter, a random access memory (RAM) is provided for storing an input data and a barrel shifter is provided for shifting the data to a least significant bit (LSB) or most significant bit (MSB) side over the number of shifts corresponding to a first control signal. Because of the provision of the barrel shifter in each sub-circuit, it is not necessary to shift a data input into an input terminal over a predetermined number of bits before storing into the RAM. Thus, the memory capacity of the RAM can be significantly reduced in size.

摘要： A frequency spectral distribution of sound signal has a plurality of discrete data at respective channels where sampling takes place. Such a spectral distribution, defining a parallel signal, is converted into a time series signal which is used to produce a peak-detected signal and a zero-cross signal. Then, based on the timing of the zero-cross signal, the peak-detected signal is compared with the original parallel signal to process the original parallel signal to be binary-valued. The present invention provides a simple hardware structure having the above-described function.

摘要： A fuel gauge unit for a fuel tank which, when the gauge unit is attached to the fuel tank, is fixed in its rotational angle in a simple fashion, and in which the fuel scale is simple and easy to inspect visually. An indicator is provided which moves back and forth in a horizontal plane when a bearing connected to a float rotates. The position of the indicator corresponds to a fuel scale, so that the quantity of fuel in the fuel tank can be determined by inspecting the gauge. On the top of the gauge unit is a protruding rectangular portion with a transparent window. This protruding rectangular portion engages in a hole in the cover plate attached to the fuel tank. The protruding rectangular portion and its hole may have a rectangular or oblong surface which serves as a rotational position lock for the gauge unit.

摘要： In order to supply a sufficient quantity of lubricating oil to the entire valve operating mechanism, we designed a lubrication device for an overhead valve engine. A first breather passage goes from the valve operating mechanism chamber to the crankcase, passing through the cylinder head and cylinder. The first breather passage opens in the vicinity of the spring retainer for the intake valve on the surface of the cylinder head which faces the valve operating mechanism chamber for the valve operating mechanism. The opening of the first passage and the vicinity of the exhaust valve are connected by a second breather passage. This second passage comprises a groove formed by cutting in the valve operating mechanism chamber surface of the cylinder head, and a tunnel formed between an oil guide wall which goes up from the valve operating mechanism chamber surface of the cylinder head and the peripheral wall of the head. One end of this groove connects to the opening of the first breather passage.
