Title: Rotating hook of sewing machine
Inventor: SHIMIZU HIROMITSU
IPC: D05B57/14
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To improve durability by enabling high speed rotation of a rotating hook without feeding lubricating oil. SOLUTION: The inner circumferential surface of the groove 2 of the rotating hook 1 is formed with a coated layer 10 constituted of the porous first layer by the electroless plating of Ni-P and the second layer made of a fluoro-resin. The rail 4 for the rotating hook bobbin case holder 3 is made of a synthetic resin such as a liquid crystal polymer. As a result, the inner circumferential surface of the groove 2 is full of wear resistance, with the wear factor set extremely small, reducing torque required for the rotary driving of the rotating hook 1, minimizing wear of the outer circumferential surface of the rail 4, enabling high speed rotation of the rotating hook 1 without feeding of lubricating oil, and thereby improving the durability of the rotating hook 1 and its bobbin case holder 3.

Abstract: PURPOSE:To easily replace only an orifice plate without removing a barrel section out of a pipeline as well as to quickly restore a device to a condition of water-run by detachably mounting the orifice plate onto the open section of a valve body rotating within the barrel section of the pipe line. CONSTITUTION:A valve body 16 is maintained in a state that respective open sections 18a and 18b are faced to an upper and a lower discharge flow path. Under this condition, respective orifice plates 19a and 19b are positioned in discharge water, so that they can be used for decompression and measurement. And when the respective orifice plates 19 are replaced as flow rate is changed, the respective open sections 18 are faced to the working port 13 of a barrel section 12 with the valve body 16 rotated, and the distribution flow path of the barrel section 12 is concurrently blocked by the side wall section of the valve body 16. Under this condition, the cover 14 of the working port 13 is removed, water standing in the respective insides of the valve body 16 and the working port 13 is bled, and the respective orifice plates 19 are replaced thereafter. By this constitution, only the orifice plates 19 can therefore be replaced with ease without removing the barrel section 12 out of a pipeline 11.

IPC: H04L25/52
Filed: 1990-11-13
Abstract: PURPOSE:To repeat inputted data in a complete form by using a demodulation clock signal which is always generated, demodulating an input signal and modulating a demodulated data signal based on a gate signal which terminates after prescribed time from the termination of data. CONSTITUTION:A demodulation clock circuit 2 always outputs the demodulation clock signal and a demodulation circuit 3 demodulates the data signal into a demodulation data signal based on the demodulation clock signal. A time limit circuit 4 outputs the gate signal corresponding to an extraction clock signal which is generated with the generation of the demodulation data signal until prescribed time elapses after the termination of the extraction clock signal from the start. A modulation clock circuit 5 outputs a modulation clock signal for modulating the demodulated signal in the demodulation circuit 3 and a modulation circuit 6 modulates the demodulation data signal into a modulation data signal only in the existing period of the gate signal by using the modulation clock signal. Thus, the lack of data when the reception of the data signal starts can be eliminated and the lack of a data trailing end part accompanied by the delay of a modulation processing can be eliminated.
