Abstract: PURPOSE:To make it possible to easily measure a peak voltage value of noise, by applying negative feedback to a plurality of amplifiers so as to bring all gains to one time and connecting said amplifiers in series while measuring the noise peak voltage value of the output terminal of the final amplifier by a peak voltmeter. CONSTITUTION:Signal source impedance elements 15, 25, 35, 45 of amplifiers 11, 21, 31, 41 use impedance values same as usual and connected to the output terminal of a preamplifier regarded to be common potential or zero impedance from the aspect of AC. Therefore, it is cleared that noise is generated in each amplifier under a fundamentally same condition. A peak voltmeter 58 is connected to the output terminal of the final stage amplifier 41. Addition is performed to all of the amplifiers at equal magnification and, by measuring and judging the noise peak voltage value Vn-p-p' of the noise output 44 of the final stage amplifier 41, the inferiority of a specimen 1 can be determined when either one of the amplifiers 11, 21, 31, 41 is inferior.

Title: Manufacture of tire antiskidding device and forming device thereof
Inventor: NAGASAWA HIDEAKI
IPC: B29L28/00
Filed: 1993-03-17
Abstract: PURPOSE:To provide a method, by which the time and labor or the work for braiding the forming stock of non-metallic antiskidding main body in the network structure can be reduced, and the forming device for the method. CONSTITUTION:The braiding of string-like stock in network structure is performed by inserting the string-like forming stock in the forming groove 15 of a rubber preforming platen 14, which is detachably wound round the drum 12 of a forming device 10, by alternately turning the platen 14 back and forth. When the forming stock is transferred to the lower semicircular portion of the rotating drum 12, the stock is pressurized by pressurizing rolls 17, which rotate in contact with the preforming platen 14, together with the preforming platen 14, resulting in forming a network-like forming body. Since the force for pushing toward the axis center of the drum 12 is worked due to the cylindrical braided formed stock, no intersecting part of the network-like forming stock gets out of the forming groove 15. Thus, a worker can concentrate all his attention to the braiding of the forming stock under the condition that one side of the drum 12 is kept as the definite checking position, resulting in making extra pressing process unnecessary.

Title: Video signal synthesis circuit
Inventor: SUZUKI YOSHIHITO
IPC: H04N5/04
Filed: 1988-03-10
Abstract: PURPOSE:To control a DC potential of a video signal reference level of an amplifier output signal automatically and accurately by using a DC feedback circuit. CONSTITUTION:When a DC potential V6 of a video signal reference level of an output signal (h) of an amplifier 25 is lower than the DC voltage set in the inside of a DC feedback circuit 26, an output signal (i) is fed back from the DC feedback circuit 26 so that the DC potential V6 of the video signal reference level of the output signal (h) of the amplifier 25 is increased. Moreover, when the DC potential V6 of the video signal reference level of the output signal (h) of the amplifier 25 is higher than the DC voltage set in the inside of the DC feedback circuit 26, the output signal (i) is outputted from the DC feedback circuit 26 so that the DC potential V6 of the video signal reference level of the output signal (h) of the amplifier 25 is decreased. Thus, the DC potential V6 of the video signal reference level of the output signal (h) of the amplifier 26 is made coincident with the DC voltage set in the inside of the DC feedback circuit 26.

Title: Emitter follower circuit
Inventor: TADEHARA KENICHI
IPC: H03F3/50
Filed: 1990-03-08
Abstract: PURPOSE:To obtain an emitter follower circuit to increase a descending speed of an output voltage without increasing the current consumption by employing a circuit comprising a 1st conduction transistor(TR) and 1st, 2nd other conduction TRs. CONSTITUTION:The circuit consists of a PNP TR 12 and NPN TRs 5, 7. Through the constitution above, when an input voltage drops rapidly, the TR 5 is cut off, In this case, a collector current of the TR 12 increases and a base current of the TR 7 increases via a capacitor 9. As a result, a pull-in current is increased and an output voltage drops rapidly, Since the flowing of a base current of the TR 7 is blocked by the capacitor 9 in the steady-state, the current consumption is not increased. Thus, through the constitution above, the descending speed of the output voltage is surely increased without increasing the current consumption.
