Title: Frequency conversion circuit
Inventor: MORI SHINSAKU
IPC: H03L7/183
Filed: 1992-10-02
Abstract: PURPOSE:To extremely accelerate pull-in speed by defining a signal, which frequency divides the input or output signal of a pulse removal circuit or a pulse addition circuit, as the control input of this circuit and providing an output signal at a frequency corresponding to the non-interger multiple of the frequency of the input signal. CONSTITUTION:At a device connecting the pulse removal circuit and the frequency divider of a frequency dividing ratio M, the output at the frequency corresponding to the (1-1/M) multiple of the input signal frequency can be provided. When the pulse addition circuit is used in place of the pulse removal circuit and the frequency dividing ratio of the frequency divider is L, the output signal at the frequency corresponding to the (1+1/L) multiple of the input frequency can be provided. The output frequency of a voltage controlled oscillator can be changed by changing the combination of respective frequency dividing ratios M1, M2... Mn, L1, L2,... Li. In this case, time from the change of each frequency dividing ratio to the fixing of the output frequency of the voltage controlled oscillator is inversely proportional to a reference frequency fr. Therefore, pull-in time can be shortened by increasing the reference frequency fr.

Title: Vibration reducing structure of turbo compound engine
Inventor: KAWATANI SEI
IPC: F16F15/12
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of an exhaust turbine output shaft by transmitting power generated in an exhaust turbine to one of a supercharger and a crankshaft with a transmitting mechanism, and reducing twist vibration facing from the supercharger to the exhaust turbine with a vibration reducing member arranged in the transmitting mechanism. SOLUTION: A capacity type supercharger 7 is driven in the operating range after starting an engine 1a, at this time, twist vibration by shock poer of high pressure gas which is received by a pair of rotors is absorbed by a rubber damper 27, and twist vibration transmitted to an exhaust turbine 11 is eliminated by a first transmission 10. Twist vibration generated by torque fluctuation of a crankshaft 2 is also transmitted from an output gear 3 to the output shaft of the exhaust turbine 11 passing a second transmission 4, a fluid joint, a continuously variable transmission 6, and the first transmission 10, the fluid joint 5 functions as a vibration reducing member, and twist vibration from the crankshaft 2 is eliminated. It is thus possible to prevent secular change of the exhaust turbine output shaft by twist vibration from the supercharger 7 and the crankshaft 2.

Title: Cylinder device
Inventor: KASHIMA MITSUHIRO
IPC: B63H20/08
Filed: 1988-10-21
Abstract: PURPOSE:To obtain a state in which contraction movement of a piston rod is locked as well as a state in which both expansion and contraction of the piston rod are locked by providing a valve, which is usually closed and which connects oil chambers on both sides of the piston to a well-chamber, and a push rod which opens these valves in turn. CONSTITUTION:When an operation lever 18 is rotated to position-'b', a push rod 16 goes into a connection part 15. As a result, a tapered part 20 of the push rod 16 pushes a valve 11 to open it, while the tip of the push rod 16 opens 12, and at the same time a bypass passage 28 connects the connection part 15 to a well-chamber 9. A piston 4 slides freely, circulating the working oil via the valves 11 and 12, while the compressed gas above the oil surface in the well-chamber 9 energizes the piston 4. Therefore, an outboard motor can smoothly be rotated by small power. After this, when the lever 18 is shifted to position-'a', the valve 12 is closed, and the outboard motor is locked. With this contrivance, the outboard motor can be supported at any rotative position with the aid of operation of the operation lever 18, and consequently no trouble will occur even in the voyage of a shoal.

CONSTITUTION:The top blowing lance which is suspended on the bath surface of the molten iron contained in the converter is constituted of a lance body 1 which conducts the oxidizing gas and is made coolable and a lance tip 2 having plural pieces of nozzle holes 4 and a notched rotary plate 3 covering part of said holes 4 is rotated by a motor 7 via a revolving shaft 5 to change periodically the flow rate of the oxidizing gas ejected from the holes 4 in the stage of supplying the oxidizing gas by the bottom blown tuyere opening under the above-mentiond bath surface and the above-mentioend top blowing lance and decarburizing and refining the molten iron. The gaseous CO generated from the molten iron is thus efficiently burned, by which the heat of combustion is absorbed into the molten iron and the blowing effect is maintained. The efficient decarburizing and refining of the molten steel are executed.
