Title: Video signal multiplexing system
Inventor: SAITO MITSUMASA
IPC: H04N7/08
Filed: 1989-03-24
Abstract: PURPOSE:To transmit the control signals without using any transmission line exclusive for the control signals by multiplexing the control signals to send them to a synchronizing signal section of a picture information signal containing no information and transmitting the control signals together with the video signals via a transmission line for video signals. CONSTITUTION:The R(red), G(green) and B(blue) signals, i.e., the outputs of a signal processing circuit 1 have no picture information in a synchronizing signal section. Then the control signals are superposed on the R, G and B signals in a picture information signal section and outputted to a monitor B. The monitor B extracts the control signals out of the R, G and B signals respectively. Then the monitor B is controlled by these extracted control signals. Thus the control signals are transmitted together with the video signals via the transmission lines L1-L3 for video signals. As a result, the control signals can be transmitted without providing any exclusive transmission line.

Title: Ultrasonic wave transmitter-receiver for flowmeter
Inventor: MOGI RYOHEI
IPC: G01F1/66
Filed: 1987-03-27
Abstract: PURPOSE:To make the directivity of an ultrasonic wave which leaks and is propagated in piping sharp, to prevent the mode wave of a harmful component from being generated, and to obtain an ultrasonic wave transmitter-receiver with improved measurement accuracy by specifying the opening length of a wedge member for fitting an ultrasonic vibrator. CONSTITUTION:When ultrasonic wave transmitter-receivers 1 and 2 send out ultrasonic waves from an upstream side to a downstream side, the received wave of an arrival ultrasonic wave is sent to a timer means 13 through a receiving circuit part 12 and the propagation time is stored in a 1st memory 14. Then when a transmission/reception switching part 10 outputs an ultrasonic wave in the opposite direction, the propagation time of the received signal is stored in the memory 14 and respective data are sent to an arithmetic means 17 to compute a flow rate which is displayed on a display means 18. At this time, when the radiation opening length of wedge members 1A and 2A is set to b=18lambda, the angle beta of the direction of a 1st zero radiation angle is nearly 3.2 deg. and the directivity is + or -1.6 deg.. In this case, a propagated wave in a 52 deg. direction is received unless the angle is 38 deg. on the reception side when the angle PHI0 of incidence is 47 deg.. In this case, almost no S0 mode is generated and a harmful wave which differs in angle of refraction is hardly generated, so the ultrasonic wave from the transmission side is received effectively at an angle theta0 of refraction as it is which is expected initially.

Title: Method for controlling pipe end in reducing mill
Inventor: KASAHARA HIROJI
IPC: B21B17/14
Filed: 1984-04-14
Abstract: PURPOSE:To increase quickly and surely the tension between stands and to eliminate thickness increase at the pipe end by controlling the roll peripheral speed of the stand on the upstream of the stand at the front end part of a blank pipe in a reducing mill so as to decelerate said speed when the bite of the front end of the blank pipe into said stand is detected. CONSTITUTION:A controller 103 controls the roll peripheral speed of the (i)-th stand so as to decelerate the same to a prescribed value when the bite of the front end of the blank pipe 101 into the (i+1)-th stand is detected by a detector 102. Said controller controls also the roll peripheral speed of the (i-1)-th stand on the upstream of the (i)-th stand so as to decelerate the same to a prescribed value, thereby applying the tension based on the speed difference larger than the speed difference in a stationary state to the pipe. The controller controls the roll peripheral speed of the (i)-th stand and the roll peripheral speed of the (i-1)-th stand so as to decelerate the respective speeds and accelerates the roll peripheral speed of the (i-1)-th stand to restore the original state when the rear end of the pipe 101 passes through the (i-1)-th stand. The thickness increase at the front end and rear end of the pipe 101 is thus effectively eliminated.

Title: Storage battery pole post material made of copper-iron alloy, having high strength
Inventor: HIGASHIYAMA KEIZO
IPC: C22C9/00
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To improve strength by specifying the composition of an alloy. SOLUTION: The pole post material, constituted by using an alloy having a composition consisting of, by weight, 30-50% Fe and the balance Cu with inevitable impurities, has higher strength while maintaining high electric conductivity equal to that of the conventional metallic Ni material, thus thickness reduction is made possible. The desired high strength cannot be secured when Fe content is less than 30%, and, on the other hand, electric conductivity is abruptly deteriorated when it exceeds 50%. Moreover, strength can be improved to a greater extent in the case where one or >=2 elements among Ni, Co, and Cr are further incorporated by 0.1-15%.
