Abstract: PROBLEM TO BE SOLVED: To reduce the size of a frequency conversion module by constructing a high frequency signal transformer and a local oscillation signal transformer on the same substrate and then integrating them. SOLUTION: A 1st transformer circuit 3 inputs a high frequency signal 101 and a local oscillation signal 109 and converts these signals into the high frequency balanced signals 102 and 103 and the local oscillation balanced signals 104 and 105 respectively with their inverted phases.

Title: Pneumatic tire
Inventor: HAMADA YASUHIRO
IPC: B60C11/03
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire which can secure rigidity of the land section in a pattern and can improve water discharge performance. SOLUTION: In the center section of a block 14, a hole 16 is formed. This hole 16 has a spiral side wall face 16A whose diameter becomes smaller as the side wall approaches the hole bottom. When a tire roles on the wet road face, the block 14 contacts the road face, the water in the tread is quickly taken in the hole 16 while turning along the spiral side wall face 16A. When the block 14 leaves the road face, discharging the water from the hole 16, the water in the hole 16 is quickly discharged along the spiral side wall face 16A. Since the water in the tread quickly comes in and out, hydroplaning performance improves.

Abstract: PURPOSE:To prevent the plugging of a rain gutter or the like by lowering a filter when the weight of the filter part exceeds the tension of a return spring, and automatically eliminating falling leaves or the like on the upper face of the filter by the repulsion of magnets. CONSTITUTION:A fitting stay 4 to be jointed to the lower part of a hinge 3 is fixed to the eaves from the lower part of a rain gutter 9. A stay 6 having a magnet 5 on the upper face is disposed on the roof side of the upper part of the rain gutter 9 and fixed to the eaves, with the position adjusted to the magnet 5 on the tip back side of a bottom part filter 1a. When falling leaves or the like are blocked by the filter 1a part and the weight of the falling leaves and the like exceeds the tension of a return spring 2, the filter 1a starts descending around the hinge 3 as the center. Upon descending to a specified place, the magnets 5, 6 installed with same poles repel each other so as to push up the filter 1a. The filter la then describes a circular arc around the hinge 3 and discharges falling leaves or the like staying on the upper f face of the filter la.

Title: Comparator circuit
Inventor: KIMURA KATSUHARU
IPC: H03K5/08
Filed: 1989-04-05
Abstract: PURPOSE:To arrange the duty ratio of an output waveform by inputting or outputting to a signal to/from an SCF LPF at a 1st clock, inputting and outputting a reference voltage at a 2nd clock so as to use the LPF in time division multiple and inputting each output to a post-stage of operational amplifier. CONSTITUTION:A signal is inputted from a 1st input terminal 1A at a clock phi1 and outputted via a 1st sample and hold circuit 3, while a reference voltage is inputted from a 2nd input terminal 1B at a clock phi2 and outputted via a 2nd sample and hold circuit 4. Time division multiplex is realized in the inside of the SCF LPF 2 by driving the LPF with clocks phi3, phi4 having the frequency twice the frequency of the clocks phi1, phi2. Thus, the signal path for the inputs 1A, 1B is the same as that of an operational amplifier being in the inside of the SCF LPF 2. That is, the same DC offset voltage is generated to both the input terminals 1A, 1B. That is, the input signal at the clock phi1 is compared with the input reference voltage at the clock phi2, then the effect by the offset voltage of the operational amplifier being the component of the pre-stage SCF LPF 2 is eliminated.
