Title: Measurement of distance to sea bottom from transponder
Inventor: MINOHARA KIYOMI
IPC: G01S15/96
Filed: 1980-11-07
Abstract: PURPOSE:To inspect easily how a fishing net sinks by measuring the distance to the sea bottom from a transponder utilizing a plurality of response signals from the transponder provided on the net. CONSTITUTION:An ultrasonic signal is transmitted to a transponder T underwater from a transmitter/receiver S1 equipped on a ship to obtain a discrete value 2n1 corresponding to the incoming and outgoing distance based on the time covered until a response signal wave from T reaches S1. A discrete value (n1+ n2) is obtained corresponding to the sum of the distance from S1 to T and the distance from T1 to S1 via the sea bottom surface 7 based on the time covered until the reflected response signal wave reaches S1 when the angle theta of incidence from T to the sea bottom surface 7 equals the angle theta' of incidence from the surface 7 to S1. A discrete value n3 is obtained corresponding to the water depth Df from S2 and the equation d=(n2<2>-n1<2>)/4n3 is computed to find the distance d from T to the sea bottom.

Title: Controlling method for change-over of combustion air quantity
Inventor: UDAGAWA KATSUNOBU
IPC: F23N3/00
Filed: 1980-11-07
Abstract: PURPOSE: To eliminate the excess blast at the start of change-over by a method wherein the blast due to the pre-established program is performed for the period of time, during which control response is unstable, just after the change-over and after the elapse of said time the normal blast turns to be performed.  
     CONSTITUTION: When the combustion state of a single hot blast stove is changed that of double hot blast stoves in parallel, the signal from a double stove combustion program setting unit 15 is added to the input signal of a single stove combustion program setting unit 14 for the period of time, during which the combustion air quantity is increased from the quantity necessary for a single stove combustion to the quantity targeted for a double stove combustion. The resultant signal is inputted as the primary signal through an adder 17 to a switching unit 19. Said primary signal is outputted through the switching unit 19 to a rotational frequency controlling device 9 so as to gradually and slowly increase the blast quantity from a blower 7 to the targeted combustion air quantity. After that, the secondary signal to require the combustion air quantity for targeted number of stoves in outputted from the adder 18 through the switching unit 19 to the rotational frequency controlling device 9 so as to blow the air quantity necessary for combustion of two hot blast stoves in parallel through the blower 7.

Filed: 1992-05-25
Abstract: PURPOSE:To eliminate interference under communication by permitting a change- over switch to be an open state, then, checking whether under usage or under incoming and separating a facsimile equipment from a subscriber line when local communication is executed. CONSTITUTION:When a soft facsimile equipment 14 is under local communication with the existing facsimile equipment 13 and there is an incoming call from an outside, the subscriber line 12 is open in the terminal of the change-over switch inside a terminal BOX15. Therefore, a incoming call from the outside is not connected so that local communication is not disturbed till completion. When an opposite party is a telephone set at the time of the incoming call, a ring-back tone is given from a receiver and the state becomes the same one as that where there is no response due to absence according to viewing from a caller side. When the opposite party is the facsimile equipment, transmission procedure for facsimile communication so that there is no problem in a communication processing since the facsimile equipment is automatically restored after the waiting time of a response signal from the opposite party passes.

IPC: F16D43/284
Filed: 1989-06-21
Abstract: PURPOSE:To reduce a transmission driving force, when a differential rotation is caused at the time of low-speed rotation of input and output shafts, by providing a guide means which is integrally rotated with a blade on the rotational central side of the blade, and also which has surfaces to which viscous fluid can be attached. CONSTITUTION:When a differential rotation is caused between an input shaft 15 and an output shaft 16, a housing 21 and a rotating body 23b rotate relatively, and viscous fluid 23c is forcibly moved by the rotating body 23b, so that a pressure is caused. At the time of low-speed rotation of the input and output shafts 15, 16, since the adhesion of a fluid 23c itself is greater than the centrifugal force due to rotation, the fluid 23c adheres to a guide means 31 and turns with it. Therefore, the forced movement distance of the fluid 23c becomes longer, and since the fluid 23c to be distributed on the inner circumferential side 40 of the housing 21 for effectively pressing an operating piston 24 is reduced as a whole, the pressure to be produced in a pressure generating means 23 is restrained, and the transmission driving force is reduced. Thus, a tight corner braking effect liable to be caused at a low-speed, large-turning traveling can be avoided.
