Title: Analog-to-digital converting circuit
Inventor: AOKI MASAHIRO
IPC: G01R19/32
Filed: 1981-03-28
Abstract: PURPOSE:To perform high-precision A/D conversion by optionally setting the upper limit  and lower limit of an analog reference voltage for converting photoelectric signals  from photoelecdric converting circuits from analog to digital, and then correcting them according to the drift of the photoelectric converting circuits. CONSTITUTION:A photodetector 1 having many photoelectric converting circuits is controlled by a control circuit 2 and a photoelectric signal read out successively by a  decoder 3 is inputted to the comparators CP5 of an A/D  converting circuit 4. An oscillator 6 is controlled by the output of the CP5 and the count value of a counter 7 which  counts a clock signal from the oscillator 6 is inputted to a D/A converting circuit 8,  which applies the CP5 with an analog reference voltage which corresponds to the count value. The CP5 stops the oscillator 6 when a level relation between the photoelectric signal and analog reference voltage is inverted, and the count value of the counter 7  at that time is outputted as the A/D-converted signal of the photoelectric signal. In  this case, the photodetector 1 generates and applies the lower-limit value and upper- limit value of the analog reference voltage through a lower-limit voltage setter 41 and an upper-limit voltage setter 42 to correct the reference voltage according to the drift of the photoelectric converting circuits.

Title: Three-phase gang breaking fuse element and gang fuse
Inventor: IKEDA KAZUTO
IPC: H01H85/36
Filed: 1990-02-26
Abstract: PURPOSE:To prevent the phase missing operation and generation of abnormal voltage by fixing shaft bearing parts of electroconductive arms to a resistance by the use of a low melting point metal, and giving each arm a resilient force to prompt the arm end into rotating in the direction of connecting with another phase adjoining. CONSTITUTION:Electroconductive arms 4a, 4b, 4c are supported by a resistor at shaft bearing parts 5a, 5b, 5c and secured to the resistor with low melting point alloy 6a, 6b, 6c. Therein a resilient force is given which prompts the arm end into rotation in such a direction as connecting with another phase adjoining when this alloy melts. When therefore an overcurrent in the small and middle amperage ranges flow for ex. through resistance 3a, the alloy piece 6a is melted by the heat emanated by the resistor 3a, and the arm 4a having received spring force rotates and its end contacts another phase adjoining, to cause generation of inter-phase short-circuiting. This eliminates impedance on the secondary side of fuse and increases the short-circuiting current, and a three-phase arc short-circuit is generated in the weld-cut parts 2a, 2b, 2c. Thus the three phases are weld-cut approx. simultaneously, and breaking is obtained simultaneously.

Title: Exhaust device for outside engine of boat
Inventor: YUKISHIMA KANA
IPC: B63H20/24
Filed: 1979-04-17
Abstract: PURPOSE: To prevent the suction of cooling water through a simple construction, by providing small holes which extend through the lower wall of an exhaust pipe for discharging exhaust gas into an expansion chamber.  
     CONSTITUTION: Three small holes 12 are opened at axial intervals through the lower wall of an exhaust pipe 10. When the pressure in the exhaust pipe is negative, exhaust gas in an expansion chamber 9 is sucked into the exhaust pipe 10 through  the small holes 12. Since the diameter of the small holes is much smaller than that  of the bottom opening of the exhaust pipe 10, the exhaust gas flows very rapidly  across the interior of the exhaust pipe almost perpendicularly to the axis of the  pipe. As a result, the rapid flow of the exhaust gas sucked through the small holes  12 in a direction B acts as a kind of air curtain to block water drops from being  sucked together with the exhaust gas into the exhaust pipe 10 in another direction  A. The water drops are thus prevented from rising further.

Title: Variable dlgital frequency oscillator
Inventor: TAKAHASHI YASUFUMI
IPC: H03L7/06
Filed: 1987-03-04
Abstract: PURPOSE:To obtain an oscillator capable of using a delay device with the fluctuation of a delay time as the oscillator, by always monitoring the number of delay stages M in which the delay time is set at one cycle T of oscillation cycles, and varying the number of the delay stages M corresponding to the delay time of the delay device even when it is fluctuated. CONSTITUTION:In a case where the number of delay stages M is fixed, when the delay time of the delay device changes to tau', it goes to a total delay time T'=(M-1)tau', and a difference   T=T'-T is generated between the one cycle T of the output of a fixed frequency oscillator, and the phase change of an oscillation output does not go to integer times the tau', and the phase jump of the  T is generated. However, by changing the number of delay stages M to M' corresponding to the fluctuation of the delay time of the delay device, only a time difference equal to the one cycle T of the output of the fixed frequency oscillator or smaller than the tau' is generated in the total delay time T' of a delay apparatus, therefore, the phase change of the oscillation output always becomes the integer times the tau', and no phase jump is generated. Consequently, the jitter of the output of the oscillator always goes less than the tau'. In such a way, it is possible to use the oscillator even in which the delay time is fluctuated as a variable digital frequency oscillator.
