Title: Method for preventing deviation in scanning line of input /output separation type scanner
Inventor: YAMAGUCHI TAKUYA
IPC: H02P5/52
Filed: 1987-11-14
Abstract: PURPOSE:To prevent deviation in a scanning line by interrupting the power supply to a synchronizing motor for driving a drum of a high rotating speed for a required period of time, then restarting the power supply upon lapse of the required time. CONSTITUTION:Respective pulses are outputted at the deviated timing for generation in the specific positions of the input drum 2 and the output drum 9 at every one rotation of said drums. Then, the pulses of the side where the rotating speed is high gradually follow up the other pulses and, therefore, the spacing between both pulses narrows increasingly. The reference periods of the specified time are, thereupon, previously determined from the time when the respective pulses on the side where the rotating speed is lower are outputted. The power supply to the motor 5 which drives the drum of the faster side is cut for the required time to lower the rotating speed of the drum on said side upon detection that the timing for generation of the pulses of the faster side enters the set reference time. Since the difference in phases is maintained by an much as the delayed component or above, the deviation in the scanning line is prevented without generating an unwanted passing.

Abstract: PURPOSE:To uniformly bond varnish to the surface of tube without permeating the varnish into braided sleeve and to obtain a braided tube to facilitate insertion operation of inserting material in the following process by carrying out varnish treatment and curing treatment while feeding a gas into the braided sleeve. CONSTITUTION:For example, a fixed amount of a gas (e.g. air) is sent from a gas inlet pipe 11 through an attached pipe 13 to a braided tube T. Further, in a state of gas fed to the braided sleeve 1, the braided sleeve 1 (braided from glass fiber, carbon fiber or polyester fiber) is introduced to a varnish treating tank 5 and the surface of the sleeve is uniformly coated with varnish to make a varnish coated braided sleeve 1A.

Abstract: PURPOSE: To efficiently heat water in a warm-water tank by heat insulating and storing generated warm water in the tank, and providing a heat transfer passage for communicating an inner space surrounded by a surrounding member with the inner space of a warm water tank casing. CONSTITUTION: Solar light emitted into a warm water tank casing 1 is emitted to the inner surface of the casing 1 and the outer surface of a surrounding member 7. The casing 1 and the member absorb the energy of the light since they are formed of a metallic material, and become in high temperature states. The interior of the casing 1 is heated, and the heated air is convected so that the entire interior of the casing 1 becomes at a high temperature. The high- temperature air at the outside of the member 7 is fed to the inside of the member 7 via a heat transfer passage 9 to heat the water in a warm water tank 4 via the wall of the tank 4. In addition, it is also heated by radiation heat from the surfaces of the casing 1 and the member 7 made of the metallic material.
