Title: Lead storage battery
Inventor: ISHIKURA YOSHIKAZU
IPC: H01M4/73
Filed: 1982-05-17
Abstract: PURPOSE:To increase the performance of a lead storage battery by preventing any separation of grains by forming a pure lead layer over the surface of a self- supporting current-collecting body made of a lead alloy by casting so that the entire surface of the current-collecting body is coated with the pure lead layer. CONSTITUTION:A current-collecting body 1 is formed by subjecting a lead-calcium alloy to casting or punching. Next the current-collecting body 1 is immersed in pure lead molten at 327 deg.C, thereafter being lifted and cooled so as to provide a pure lead layer 2 over the entire surface of the current-collecting body 1, thereby making a current-collecting member for a lead storage battery by taking advantage of the difference between the melting point (327 deg.C) of pure lead and that (more than 327 deg.C) of the calcium alloy. As a result, since separation of grains which may be caused due to the difference between the corroding mechanisms of charging and discharging is hardly caused, decrease in the characteristic of the battery which might be caused by long-period charge-and- discharge cycles can be prevented by preventing any cutting or the like of the current-collecting member.

Title: Laser beam machine
Inventor: OKAZAKI AKIYASU
IPC: B23K26/064
Filed: 1984-04-27
Abstract: PURPOSE:To improve work efficiency by arranging a working head for cutting between a working head for welding and a working head for heat treatment. CONSTITUTION:When a working head 6 for cutting is arranged between a working head 5 for cutting and a working head 7 for heat treatment, for instance, in case of cutting a long-sized steel plate in the middle and forming a short-sized steel plate of the same dimension, the middle of a steel plate fixed on a moving table 16 is placed under the working head 6 for cutting. As the steel plate is extended by equidistance from the corresponding place of a bed 6 in the direction of the working head 5 for welding and the working head 7 for heat treatment, many places for steel plate arrangement are not necessitated. As the working head for cutting 6 is arranged to a beam waist 1B, also, the cutting width can be lessened when an article to be worked 15 is cut according to the beam mode.

Abstract: PURPOSE:To provide the intrusion monitor picture device which detects an intrusion and reduced erroneous reports and can monitor the intrusion in a wide range. CONSTITUTION:Feature data of the area, the movement direction, and the movement speed of an object acquired in a taken-in monitor area is extracted by a detection object feature extracting part 8.

Title: Constant voltage power source
Inventor: ISOBE MASANORI
IPC: G05F1/10
Filed: 1989-04-03
Abstract: PURPOSE:To prevent breakdown by passing an OFF command signal fed from the input terminal of a primary power source through a constant current circuit, upon detection of overcurrent, and feeding an OFF command signal having constant level against fluctuation of primary source voltage to a command circuit thereby interrupting output to a load. CONSTITUTION:When pulse signals are applied onto an OFF command terminal 4 and constant voltage is provided through an output terminal 2 to a load, an H level signal is fed from a current judging circuit 9 to a switch 11 if load current exceeds over an allowable level due to abnormality, such as short circuit fault, of the load and the switch 11 is turned ON to conduct a Tr 13. But since the voltage across a constant current setting resistor 14 is maintained constant by the voltage of a reference voltage source 12 and the bias voltage between the base and emitter of the Tr 13, current flowing through the Tr 13 to the OFF command input terminal of a command circuit 6 is maintained constant regardless of the primary source voltage. Consequently, the command circuit 6 produces an L level signal and a voltage stabilizing circuit 7 interrupts provision of output thus protecting the constant voltage power source.

Title: Signal switching circuit
Inventor: TAKEDA TADASHI
IPC: H03K17/00
Filed: 1986-04-11
Abstract: PURPOSE:To switch output signals by a receiver without using any changeover switch by using an opposite-polarity transistor(TR) which is applied with a proper fixed bias as a load on the TR of one signal output circuit. CONSTITUTION:An amplifier on an optional signal side is selected between amplifiers 1 and 2 by a switch 3. When the amplifier 2 is selected with a signal input B, a signal is supplied to a buffer amplifier composed of a bias resistance 6, an amplification degree setting resistance 8, and a TR 7 through a capacitor 5. The amplifier 1, on the other hand, is selected with a signal input A and its output appears at a terminal OUTPUT through a capacitor 4. At this time, collectors of TRs 7 and 10 are connected as the load on the amplifier 1, but base sides of the TRs 7 and 10 are fixed in terms of AC, so extremely high impedance is obtained and its influence is therefore a little. Consequently, the signals A and B having optional output levels can be switched with the switch 3 and the need for output signal switching is eliminated.

Filed: 1979-07-04
Abstract: PURPOSE: To permit plate cutting operation by only one prime piler without having effect on line speed of previous process by automatically detecting the number of piled plates to carry out automatic speed reduction and stoppage.  
     CONSTITUTION: Length of cut plate and unit number of piled plates are set in a digital switch 19. The plates piled on a piler 5 are counted at point B to enter a counter 24. Plate length signal 11 and speed signal 13 produce speed reduction signal 15 for commanding the speed reduction of plate cut before a predetermined number of plates are cut and stoppage signal 16 for commanding the number of plates to be left on a conveyor at the time of the stoppage. Digital switch signal 20 and count signal 25 are operated to supply signals 26, 27, 28 which command the number of plates to be piled momentarily. Coincidence of the signal 15 with the signal 26 reduces the speed of plate cut and coincidence of the signal 16 with the signal 27 stops the plates.
