Title: Channel selection device
Inventor: SUZUKI TOMOHIRO
IPC: H03J7/28
Filed: 1985-07-22
Abstract: PURPOSE:To stabilize a local oscillating frequency by providing the 1st reference frequency setting means, an operating means and the 2nd reference frequency setting means. CONSTITUTION:The 1st reference frequency setting means A sets the reference frequency to a frequency of a minimum step width of frequency fine adjustment before the frequency fine adjustment. An operation means B between the tuning frequency after the frequency fine adjustment and the center frequency of a desired channel and the 2nd reference frequency setting means C sets the reference frequency to n/m multiple of the frequency of the minimum step width in response to the difference frequency. The reference frequency is selected as the minimum step width frequency at the frequency fine adjustment, the fluctuation of an error voltage passes easily through a filter circuit, the response time is shortened, and the reference frequency is selected to n/m multiple of the minimum step width after the frequency fine adjustment and the fluctuation of the error voltage is limited by the filter circuit. Thus, the local oscillating frequency, that is, the tuning frequency is made stable.

Title: Air cleaner
Inventor: YOSHIKAWA TATSUO
IPC: B03C3/68
Filed: 1988-06-29
Abstract: PURPOSE:To ensure that maintenance services are easy and high dust collection performance is maintained constantly by connecting an input signal to a control circuit through a switch and wiping off dirt sticking to an electric discharge device using a high voltage. CONSTITUTION:Dirt such as grease contaminates an electric discharge element 18 and its accumulation deteriorates electric discharge performance, resulting in a decrease in the capability of dust collection. In such a case, the input to a high voltage generation circuit 14 is increased by actuating a control circuit 21 to double a high voltage output compared to the normal output. Subsequently, a discharge current is increased so that it becomes close to the form of a spark current. Thus dirt such as grease on the surface of the electric discharge element 18 is burnt down to recover a clean condition and also high dust collection performance is obtained.

Filed: 1979-12-13
Abstract: PURPOSE:To lower the winding temperature effectively with limited manhours by reducing a rise in the temperature through cooling from four or three directions of a cylindrical coil wound in multiple which undergoes alternative right and left winding repeated by in shifting thereof. CONSTITUTION:Two each of six (A-F) conductors 1 are laid one upon another radially to form conductor trains which are so arranged axially as to form a cooling path each between the conductor trains. A layer 43 is spirally wound along a cylindrical surface of each conductor train axially spaced and then, a similar layer is wound on the layer 43 separated from the cooling path 44 to make three parallel double-layer cylindrical windings. In this case, these cylindrical windings undergo alternative right and left twistings repeatedly in shifting between the layers 43 and 45. In addition, three conductor trains 41 are changed in the axial order at a point where a passing is made across the end of the cylindrical winding on the layer 43 and the end of the cylindrical winding on the adjacent layer 45. Thus, the temperature of the windings can be lowered effectively with limited man-hours.

Abstract: PURPOSE:To increase the detecting signal, by using at least one stage of pattern just before a detector larger than other patterns among plural stage of patterns formed in the progressing direction of bubbles in a bubble expander. CONSTITUTION:As one bit 9 just before a bubble detector 5, a pattern 10 having the shape of modified double chevron patterns and a large pitch is used in comparison with other patterns having a simple chevron pattern of the said bubble expander 6.

Since the state of bubbles just before the detector passes through the expander, the bubble is expanded fully and not effected largely with the pattern of several bits just before the detector. Thus, the detection signal is increased without blocking the expansion of the bubble.
