Title: Small-sized dust collector
Inventor: YOSHIDA ISAMU
IPC: B01D46/00
Filed: 1978-08-01
Abstract: PURPOSE: To enhance the dust collection effect by permitting the suction air to easily ascend from below into the dust collector, by exhausting the air sucked, filtered and purified by the fan through special filter downward in the form of an umbrella.  
     CONSTITUTION: A dust collector consists of a cage type windmill 8 rotated by a motor 6, and a special filter 12 which is effectively and continuously adsorbing and capturing dust and harmful substance in the air, and the air is sucked from a suction port 14, and is filtered and cleaned by a filter 12. Wind force is applied by the effect of vane 9 opened in the body of the windmill 8 and stationary vane 5, and the air is exhausted from an exhaust port 4 formed with umbrella-shaped upper outer shell 1 and lower outer shell 2. Since the lower outer shell 2 is made slightly shorter than the upper outer shell 1, the exhaust air is injected downward in inclined direction in the form of an umbrella, acting like an air curtain, so that the suction air may easily ascend from below up into the dust collector.

Title: Sampling frequency converter
Inventor: ONISHI MAKOTO
IPC: H03H17/02
Filed: 1987-04-20
Abstract: PURPOSE:To simplify the circuit constitution and to make the interpolation highly accurate by using a time changing coefficient noncyclic filter and using a phase locked loop so as to convert the sampling frequency. CONSTITUTION:The input sampling signal having a frequency fS1 is inputted to a phase comparator 1, where it is subject to phase comparison with an output being the result of 1/M frequency division of the oscillating frequency of a VCO 2 by a frequency divider 4 and the output is inputted to the VCO 2. Thus, the center frequency fC of the VCO 2 is locked to the least common multiple of the frequency fS1 and the output sampling frequency fS2. The output of the VCO 2 is subject to 1/N frequency division by a frequency divider 3 and the frequency becomes the frequency fS2 to apply phase locking of the input/output sampling frequencies. Then the count of the frequency divider 4 is latched and the frequency fS2 is used as the latching clock to read out a time changing coefficient. On the other hand, the input data f<(n>T<)> is inputted to memories 9-12 via delay elements 6-8 to write the product of the time changing coefficient. The result is summed by adders 13-15 and the result is outputted. Thus, high- order interpolation is applied while using digital signals and highly accurate processing is attained and the circuit constitution is simplified.

Filed: 1982-06-03
Abstract: PURPOSE:To enable to enhance a heat-collecting efficiency and to protect a heat collector, by a method wherein a slidable shutter is provided which can shieldingly cover a heat-receiving surface of a heat collector, and an upper surface of the shutter is formed as a hight-reflecting surface so that reflected light can be projected to the heat collector when the latter is not shielded. CONSTITUTION:When collecting heat to the most, the entire body of the slidable shutter is fixedly maintained by guiding by skewly upwardly extended sides 10b of guide rails 10, whereby heat is collected at the entire surface of the heat collector 8. In this case, the shutter 11 functions as a reflecting plate for the heat collector 8, that is, the solar heat is projected onto the collector 8 by the shutter 11. Therefore, heat is collected efficiently. When reducing heat-collecting power, for example, a half of the shutter 11 is slidden to cover the surface of the heat collector 8. Further, when heat collection is not required, the entire body of the shutter 11 is moved to the side of the collector 8 to shield light, thereby stopping the collection of heat and protecting a glass plate or the like constituting the heat-receiving surface.
