IPC: B63H5/16
Filed: 1981-09-18
Abstract: PURPOSE:To raise the turning efficiency of a propeller by guiding sea water toward said propeller while inclining a propeller post in the stem direction in a small fishing boat provided with said propeller post on the rear end of a plate shaped hill piece projected on the bottom of the boat. CONSTITUTION:A propeller 12, a steeling plate 13, and a hill piece 14, etc., are provided on the stern part of a hull 11, and a propeller post 15 on the rear end of the hill piece 14. The propeller post 15 is provided while iclined by about 30 to 60, and the cross section thereof approximately forms a right triangle. Accordingly, said cross section apparently presents an acute angle to sea water flowing around said cross section, so that turbulance behind a turbulent flow is remarkably reduced compared with a case where said cross section was formed in a vertical direction against the sea water, allowing the resistance against sailing of the fishing boat is reduced furthermore. Besides, a flow (f) inducing sea water to flow toward the propeller 12 is generated.

Abstract: PURPOSE:To provide a circuit constitution capable of obtaining a sine wave free from harmonic distortion with a simple filter with in a sine wave generating circuit which generates the sine wave from a pulse signal. CONSTITUTION:A switching pulse V(1) having a duty ratio higher than 1/2 and a switching pulse V(3) obtained by the inversion of a signal which has the phase different from that of the pulse V(1) by 180 deg. are synchronously applied to two switching elements 9 and 10 of a tristate output circuit to generate a tristate signal, and the tristate signal V(4) which passes a bias circuit 2 is outputted to a low pass filter 3. The tristate signal has less harmonic components because approximating a sine wave, and especially, the third harmonic component is completely eliminated when the duty ratio is set to 2/3, and thus, the sine wave free from harmonic distortion is obtained with the simple filter.

Abstract: PURPOSE:To facilitate the selection of an optional oscillation frequency, and to improve the stability of the oscillation frequency by calculating a difference between a number of pulses obtained by a pulse counting means, and a reference number of pulses and supplying a calculated difference data to a voltage controlled oscillator after converting it into an analog voltage. CONSTITUTION:An oscillation output frequency (f) from the voltage controlled oscillator VCO1 is stepped down to 1/n by a step-down circuit 3, and the signal of a frequency f/n is generated. Then, a pulse number data fT/n during the period T of a clock signal is obtained by a pulse counter 5, and is supplied to the input terminal of one side of a digital subtraction circuit 6.

Title: Thick film resistance element
Inventor: SHIOIRI NOBUO
IPC: H01C17/24
Filed: 1987-06-16
Abstract: PURPOSE:To prevent burning due to surge by shaping the edge opposite to that of a notch into a semicircle. CONSTITUTION:A thick film resistance element 7 is fixed on conductor patterns 1 and 2 whereon a notch 4 is formed through trimming for resistance adjustment. The shape of the edge 7b opposite to an edge whereon the notch 4 is provided is semicircular. Accordingly, the gap between the edge 4a of the notch 4 and the edge 7b is not extremely narrow and thereby centralization of flows of current 8 is decreased in comparison with that for the conventional shape. Since the electric field is small in surge, discharge seldom occurs and the burning due to surge is thus prevented.

Abstract: PURPOSE:To improve the reliability of a device together with reduction in its size and weight, by constituting a wiper driving control circuit with an electronic circuit to form it into an integrated circuit (IC). CONSTITUTION:A flip flop circuit 12 controls electric power to be fed to an electric motor 1 or stopped by means of an electronic pulse input to each terminal 12a, 12b of said circuit 12.
