Filed: 1990-06-01
Abstract: PURPOSE:To control the oscillating frequency of an oscillation circuit electrically with simple circuit constitution by providing a means controlling the output amplitude voltage of a 2nd NOT circuit and controlling the frequency with a voltage. CONSTITUTION:The output of a NOT circuit 1 is connected with the input of a NOT circuit 2, a resistor is connected between the input of the NOT circuit 1 and the output of the NOT circuit 1, an amplitude control circuit 3 is connected to the output of the NOT circuit 2, its output 9 is connected to the input of the NOT circuit 1 through a capacitor 5, and the amplitude of the amplitude control circuit 3 is controlled by an amplitude control voltage 10. Thus, when the output 9 of the amplitude control circuit 3 is large by the amplitude control voltage 10, the oscillating frequency is decreased and when the output 9 is conversely decreased, the oscillating frequency is decreased. Thus, the oscillating frequency of the oscillation circuit realized with simple circuit constitution employing a logic circuit is controlled by a voltage.

Filed: 1993-05-19
Abstract: PURPOSE:To provide a lead-acid battery capable of safely lowering function before the battery is suddenly laid in an abnormal state and notifying it with a feeling of deterioration by setting the intersection in a part of an expand grid body to an intersection area smaller than those of other intersections. CONSTITUTION:After the long-term use of an expand network grid 1, the corrosion of the intersection parts 3 of the network skeleton is rapidly accelerated in a highly concentrated diluted sulfuric acid, and its superiority depends on the intersection area of the section part 4 seen from the direction vertical to the grid body plane of the part in which the skeletons of the crossing intersection parts 3 where adjacent meshes are mutually crossed in the grid body 1 are continued and duplicated. Thus, a part of intersections of a plurality of intersections of the grid body 1 is set to an intersection area smaller than other intersections, whereby this intersection is broken prior to other intersections so that a feeling of deterioration can be given to a user. This period can be controlled by properly selecting the intersection area.

Abstract: PURPOSE: To improve the capacity of ignition in a magneto electric ignition device by providing a generating coil to switch on and off a discharge semiconductor element separately from a generating coil for sparking for increasing the energy of igntion.  
     CONSTITUTION: At first, a condenser 11 is charged in the illustrated direction by a voltage V 2  in (c) direction of a generating coil 7. As the charging of this condenser 11 proceeds, a transistor 6 is on. When a generating coil 1 outputs a voltage V 1  in the direction of an arrow (a) during "on" of the transistor 6, a current I 1  begins to run in the transistor 6, and increases according as the voltage V 1  is increased. Meanwhile, when the voltage V 2  in the generating coil 7 is directed as an arrow (d) shows, a gate signal is sent to an SCR12. When the gate signal reaches to the trigger voltage of the SCR12 is closed, and consequently, the transistor 6 is off. Accordingly, a current I 2  suddenly begins to run in a primary coil 3 of an ignition coil 2, and a high voltage is induced in a secondary coil 4 for generating a spark in an ignition plug 5.

Title: Organic electrolyte cell
Inventor: SUGIMOTO TOYOJI
IPC: H01M4/66
Filed: 1986-06-18
Abstract: PURPOSE:To make a preparatory discharge process unnecessary and to prevent the loss of an extensive cell capacity, by furnishing a graphite layer with a water-soluble high polymer having a reducing radical, such as methylcellulose or carboxy methylcellulose, as a binder in the moleclues, to the surface of a positive electrode collector. CONSTITUTION:Carboxy methylcellulose of 10 wt% is solved in a water or a warm water to make an adhesive solution, to which graphite powder of 20 to 30 wt% to the carboxy methylcellulose solution is added and dispersed to make a graphite paste. The paste is spread on an expanding metal of lithium and a dried thin graphite layer is formed over the surface of a positive electrode collector 2. When a paste of a positive electrode agent 1 with carbon fluoride as the active substance is spread and dried over the positive electrode collector 2 formed in such a way, the carboxy methylcellulose over the positive electrode collector 2 reacts with the separated fluorine existing over the carbon fluoride to reduce the carbon fluoride surface. Therefore, no preparatory discharge process is necessary and the loss of the extensive cell capacity can be prevented.

Title: Eaves member
Inventor: KATO TOSHIRO
IPC: E04D3/40
Filed: 1991-06-13
Abstract: PURPOSE:To obtain an eaves member with a good appearance which is not broken by fallen snow or the like. CONSTITUTION:The front of eaves is fitted to the edge of the eaves and protruded to bend toward the roof and a groove 1a extending in the direction along the eaves front is provided on the face diagonally directing upward of the protruded bent outer surface. And a vertical groove 1b separated from the groove 1a is provided for dropping water. Since thawed water flows down through the groove and vertical groove, the shawed water drops from a specified position. And thawed water flows down along these grooves and hence, dusts or the like do not stick to the fascia board and it keeps a good appearance. And since the sectional shape of the eaves member has a nearly C-form bent and protruded toward the outside direction and further the groove and the vertical groove are provided in the direction of the eaves front at the curved face, a high rigidity can be obtained and hence, damages resulting from thawed water do not occur.

Filed: 1983-08-03
Abstract: PURPOSE:To attain sure protection of an output transistor (TR) by operating a differential amplifier with a detected current and controlling the output TR in response to the output of the differential amplifier. CONSTITUTION:When an output terminal 12 and a ground point GND are short- circuited, a base potential of a TRQ14 is decreased less than the base potential of a TRQ15 so as to turn the TRQ14 on. A current fed to a common emitter of the TRs Q14, Q15 flows to the ground point GND via the TRQ14, and a resistor R8. Thus, a TRQ16 is turned on, a base current of driving TRQ7 of an output TRQ1 is led to the ground point GND and the TRQ7 is turned off. The turning- off state of the TRQ7 turns off the output TRQ1, which is thus protected.

IPC: F04B15/02
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an impact and pulsation by conveying ready-mixed concrete by alternately operating a pair of cylinders. SOLUTION: The solenoids (a) and (b) of an electromagnetic switch valve 9 are excited by switching signals for lead switches LS1 and LS2 and a discharge amount of working oil of a variable displacement hydraulic pump 20 is decreased. Thereby, hydraulic cylinders 2 and 3 for drive start discharge operation at a low speed by a small amount of working oil fed with a pressure from the hydraulic pump 20. When, since a discharge amount of working oil of the hydraulic pump 20, which is decreased once, is gradually increased, hydraulic cylinders 2 and 3 for drive gradually increase a working speed along with the increase of a discharge amount of working oil and a discharge amount of working oil reaches a given amount, a current speed forms a normal given speed, and discharge operation is continued as it is. Hydraulic cylinders 2 and 3 for drive start discharge operation at a low speed and the speed is gradually increased, whereby the occurrence of an impact and pulsation is effectively reduced.
