Title: Rotary brush for suction port of vacuum cleaner
Inventor: IGUCHI AKIO
IPC: A47L9/04
Filed: 1990-09-21
Abstract: PURPOSE:To enhance the nerve of free edges of blades and increase the mass of the free edges for improving the dusting effect by a method wherein flexible blades are projected outward from the: outer face of a brush head drum and extended in the axial direction of the brush head drum, and thick protruding parts are provided along the free edges of the blades. CONSTITUTION:Blades 17 are helically extended in the axial direction of a brush head drum 16, and thick protruding parts 20 are provided along the free edges of the blades 17. Thereby, the nerve (stiffness) of the blades 17 of a rotary brush 14 is increased and the scraping force generated by the rotation of the brush head drum 16 is enhanced. In addition, the dusting effect on a floor, a carpet, etc., is improved due to the inertia effect of the thick protruding parts 20 caused by the rotation of the brush head drum 16. Further, as the protruding part 20 has an arc-like cross section, the air flow along the free edge of the blade 17 is relatively smooth when the blade 17 is revolved at a high speed. As a result, unlike conventional rotary brushes, the rotary brush does not generate large air swishing noise resulting from a high rotating speed of the blades 17 and a silent suction attachment can be obtained.

Title: Signal interpolation circuit
Inventor: ISHII SATORU
IPC: H03M1/64
Filed: 1988-10-12
Abstract: PURPOSE:To improve the interpolation accuracy by constituting a means converting an optional phase angle signal being the result of mixing biphase signals with different phase angle or their inverting signals in a prescribed ratio into a rectangular wave signal with a comparator having a hysteresis and making the width of hysteresis proportional to the amplitude of the mixed signal. CONSTITUTION:Signals with phase angles of 0 deg., 90 deg. obtained from input terminals 1, 2 through buffers 3-5 are mixed by a mixing means 16, resulting in producing signals with phase angles of 0 deg., 45 deg., 90 deg., 135 deg.. The phase angle signals are converted into a rectangular wave signal by a conversion means 17 and inputted to a pulse generating means 18. Since the hysteresis width of a comparator 19 is set to a value proportional to the amplitude of the mixed signals, even if the amplitude of the mixed signal differs, the operating position of the comparator 19 is deviated by the same phase angle and the interpolated pulse strings are arranged at an equal interval.

Title: Power supply for device to be implanted inside body
Inventor: SHINOHARA TATSUMI
IPC: A61N1/378
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To transmit power efficiently by letting a power carrier frequency control circuit change the power carrier frequency and by controlling it so that the output voltage inside the body can be maximized, when a power transmitting circuit for transmitting the power carrier is provided outside the body and it is linked to a power receiving circuit. SOLUTION: In a power carrier frequency control circuit 8, a CPU 23 stores a received output voltage value into a memory 24 and controls the power carrier frequency in such a way as to increase it, for example, a bit higher than the current frequency. When the output voltage value becomes equal to the voltage value stored in the memory, the control is ended. Conversely, when the output voltage value based on the received voltage is lower than the previously stored voltage value, the power carrier frequency is a bit lowered below the current frequency to perform the control of comparing the received output voltage value with the stored one. This way, the power carrier frequency is controlled so that the received voltage of the power receiving circuit 1 can always be maximized.
