IPC: H03K3/2885
Filed: 1980-04-02
Abstract: PURPOSE:To realize not only a high speed but the low power consumption for a comparator circuit, by supplying alternately the working currents by the synchronous pulse for both the 1st circuit system that processes the input and output signals of a latch holding circuit and the 2nd circuit system that processes the input and output signals of a differential amplifying circuit. CONSTITUTION:The current switches 7-A, 19-A and 22-A are turned on and the current switches 8-L, 20-L and 23-L are turned off respectively when the clock pulse phi is at the H level and the clock pulse -phi is at the L level. Thus the current source 9 makes active the differential amplifying circuit consisting of the transistors 1-A and 2-A. Then an output is produced at the load resistances 3 and 4. When the clock pulses becomes contrary to each other, the switches 8-L, 20-L and 23-L are turned on. Thus the source 9 makes active the latch holding part comprising the transistors 5-L and 6-L to give a latch holding to the outputs of the resistances 3 and 4.

Abstract: PURPOSE: To stack materials regularly by a mechanism wherein an auxiliary con veyor is continuously mounted in front of a movable frame, and a horizontally holding lever, which horizontally holds the auxiliary conveyor regardless of the undulations of a conveyor frame in interlocking with an operation lever, is connected to a  front end of the auxiliary conveyor.  
     CONSTITUTION: A front conveyor roller 11 advances with a rise at a location upper than a horizontal location, draws out a movable frame 10 and decreases the amount of a belt delivered by means of an adjusting roller 13. Since the length of a conveyor 15 is extended and a nose of the conveyor 15 is given a rise-and-fall function passing on a perpendicular, an auxiliary conveyor 38 continuously mounted to the conveyor 15 also conducts rise-and-fall action in which the nose passes on a perpendicular. At the same time, since a conveyor frame 39 is pushed up when the frame 39 is horizontal or lower and it is pulled up when it is horizontal or upper by means of a horizontal holding lever 41 interlocking forming a pantograph together with an operation lever 23 in a nose of the conveyor 38, the auxiliary conveyor  38 holds horizontality, and forwards materials. Thus, the materials can be stacked regularly.

Filed: 1991-02-15
Abstract: PURPOSE:To prolong the life of seal and reduce the accumulated quantity of dust and sediment by fitting a conical cover to a position right above the column of a shaft, in the non-contact state with other members but with its joined part to the shaft in the watertight state. CONSTITUTION:A conical cover 12 formed of metal or resin molding material is fitted to a shaft 5 to be joined together. A joined part 13 is formed to be watertight by means of close-fitting, closing/fixing a gap part with adhesive, or the like. The cover 12 larger in the outer diameter than a column 4 is fitted in the non-contact state with the column 4 and also with a dust seal 14 provided between the column 4 and the shaft 5. Dust A, rainwater, and the like fall or flow down along the upper inclined face of the cover 12, and the dust A falls further effectively since the cover 12 is rotated together with the shaft 5 by the operation of a steering wheel. As a result, the sliding contact part, with the shaft 5, of the lip 14a of the dust seal 14 is kept clean, and the life of seal can be prolonged.

Title: Controlling circuit for offensive odor alleviator of kerosene stove
Inventor: AIGA JUNJI
IPC: F23D3/18
Filed: 1985-03-05
Abstract: PURPOSE:To prevent a main transistor from returning to an OFF condition again by erroneous action of an arithmetic amplifier, by cutting off the circuit between the main transistor and the arithmetic amplifier while the action of an arithmetic amplifier is unstable, by providing a delay transistor between the base terminal of a main transistor and the output terminal of an arithmetic amplifier. CONSTITUTION:The output terminal of an arithmetic amplifier 4 is cut off from the base terminal of a main transistor Tr1, since a delay transistor Tr5 is in an OFF condition for a while after a main transistor Tr1 is turned ON. Accordingly an odor alleviator can be actuated without fail because the main transistor Tr1 is not turned OFF if the output of an arithmetic amplifier 4 is inverted as its behavior is unstable soon after power voltage is impressed on it. The terminal voltage of a back-up capacitor C2 is raised to a predetermined value and the delay transistor Tr5 is turned ON when the behavior of an arithmetic amplifier 4 is stabilized. After that, the main transistor Tr1 is turned OFF when the arithmetic amplifier 4 is inverted by the terminal voltage of a capacitor C3 of a time-constant circuit when its voltage is heightened. The action of an odor alleviator can be stopped without fail after a predetermined time has passed after an extinguishing operation.
