Title: Time signal detector
Inventor: TOYODA MITSURU
IPC: G04R20/20
Filed: 1981-08-13
Abstract: PURPOSE:To detect a time signal with high accuracy and with use of a digital filter of high accuracy, by controlling a counter with an OR signal of the binary digit output corresponding to the signal of time signal and the rectangular wave signal having a prescribed frequency and duty. CONSTITUTION:The signal (d) obtained by binary digit coding the time forecasting signal of a sine signal of 440Hz, etc. and the signal (e) having a frequency 512Hz, etc. approximate to the frequency of the signal (d) and a prescribed duty having the width of the zero-level part smaller than the value approximate to the width of the signal (d) are applied to an OR circuit 21 of a counter circuit 11 which forms a digital filter. With an OR process of the signals (d) and (e), the prescribed seven pulses are produced during a prescribed period of 0.1sec, etc. among period to generate pulses having a wide width. During this period, the resetting is released and a counter 22 counts the clocks. Then the output of a counter 23 is inverted to a high level by the output of a prescribed count time constant. The outputs of the counter 23 are counted by a time signal sound counter circuit 12. Thus the time signal sound is detected with high accuracy through a digital filter of high accuracy that can clearly discriminate the unstable noises having approximate levels of frequency.

Title: Fuel tank of service machine
Inventor: MIZUSHIMA SADAO
IPC: B60K15/03
Filed: 1983-07-12
Abstract: PURPOSE:To surely prevent fuel leakage by forming a fuel supply opening on the upper face of a fuel tank at the end part thereof which comes uppermost when a service machine falls down in a certain direction and upwards swelling the upper face part of the tank except the fuel supply opening. CONSTITUTION:In a service machine such as a lawn mower or the like, the upper wall 11 of an engine unit cover, the partition wall 13 formed downwards from said wall and a box 15 define a fuel tank 20. A recess 12 is formed on the cover's upper wall 11 and has a fuel supply pipe 21 opened thereat. A tank's top part 22 other than the part around the pipe 21 is swelled upwards. The tank 20 is filled with fuel up to the level L flush with the bottom of the recess 12 and a cap is then tightly screwed on the supply pipe 21. In such condition, if the service machine falls approximately 90 deg. sideways to the left, fuel is flooded into the space S1 which comes to the position below the supply pipe 21 at that time. Since the fuel level is beneath the line extending from the left-side inwall of the supply pipe 21, no fuel leaks from the breather hole of the cap.

Abstract: PURPOSE:To make it possible to exactly execute the channel selecting operation, by controlling the switching means by a muting output signal, short-circuiting the resistance connected between the reference voltage terminal and the AFC terminal, by turning on the switching means, and widening the S curve band. CONSTITUTION:In case of stationay receiving and manual receiving after the search channel selection, an FM detective output is received from the FM detector 1, and it is provided to the S curve terminal of LSI5 for channel selection control through the operational amplifier 15 from the AFC terminal 2. In this case, in case the local oscillation frequency has been varied due to a variation of ambient temperature, or mechanical vibration, the muting output terminal 17 of LSI5 for channel selection becomes a high level by turning on the preset switch (not shown in the figure), and FET10 becomes on. Accordingly, as a result, the resistor between drain and source of FET10 is inserted in parallel into the resistance 18 connected between the terminal 2, 4 of the FM detecting circuit 1, and therefore the band width of the S curve is widened and the channel selection can be executed exactly.
