Title: Runaway detection circuit
Inventor: SUENAGA FUMIHIRO
IPC: H04Q1/22
Filed: 1989-03-16
Abstract: PURPOSE:To detect malfunction and runaway of a pushbutton signal/multi- frequency signal receiver by providing a signal presence identification detection circuit, a signal absence identification detection circuit and an OR circuit sending the OR of outputs of the identification detection circuits. CONSTITUTION:A counter transmission circuit 11 receives a bus control signal sent from an interface circuit to a receiver and an output by a tetral counter is inputted to a signal presence identification detection circuit 12 and a signal absence identification detection circuit 13. The signal presence identification detection circuit 12 and the signal absence identification detection circuit 13 compares and detects the signal from the counter transmission circuit 11 with the identification output signal sent to the interface circuit from the receiver and the signal presence identification detection circuit 12 detects it that the period of the identification output signal from the receiver does not exist. The signal absence identification detection circuit 13 detects it that the identification output signal from the receiver exists even when the signal should not exist and a runaway detection output is sent to the CPU from the OR circuit 14. Thus, malfunction and runaway of the pushbutton signal/multi-frequency signal receiver are completely detected.

Title: Dimmer control apparatus
Inventor: NAMIKOSHI YASUMASA
IPC: H05B37/02
Filed: 1978-05-31
Abstract: PURPOSE: To prevent breakdown of thyristor due to surge voltage and also prevent production of arc at contacts by associating the switching of the power source switch and the control of thyristor.  
     CONSTITUTION: When a control terminal a is input with control signals, a transistor 17 is powered for operating a relay 18 so as to close a contact 5. Then signals delayed by a delay circuit 14 reach a point b and thereby a transistor 19 is powered for operating a relay 20 so as to close a contact 6. A thyristor 3 is continued with a necessary phase for supplying electric power which is phase controlled by a load 4. If the control signals are removed from the control terminal a, the contact 6 opens for discontinuing the thyristor 3. Therefore, the contact 5 also opens and thereby the circuit is broken off completely.

Title: Lead-acid battery
Inventor: AKITA HISAYOSHI
IPC: H01M50/541
Filed: 1986-03-24
Abstract: PURPOSE:To improve workability and make it possible to enlarge the plate dimension by connecting lugs of plates by soldering. CONSTITUTION:Anode plate lugs 4 are allowed to approach inward in the upper part of a separator 3 and connected with solder 5 to connect anode plates 1 each other within the same cell. When cells are connected via a partition 7, the anode plate lug 4 and a cathode plate lug 6 are connected with solder 5 in the upper part of the partition 7 to connect a cathode plate 2 and the anode plate 1. The lugs 4, 6 are formed in an L shape so that the width at the upper end is widened. That prevents increase in electric resistance caused by decrease in the cross section as the result of melting of the lugs in soldering. Thereby, in a small size battery, the installation of a strap and a post can be eliminated and the dimension of a plate is increased to ensure the capacity.
