Title: Traveling device for sheet body
Inventor: TERAKAWA MASATSUGU
IPC: B65H18/10
Filed: 1986-03-07
Abstract: PURPOSE:To reduce the noise of a traveling device by installing sheet guide rollers on both end parts of a board-like body which is provided at the back of a sheet body, resiliently displaceably to approach and separate from said board like-body. CONSTITUTION:Both end parts of a sheet body 24 which is slidingly in contact with a front face 23 which is the smooth surface of a board-like body 22, are put around a pair of wind-up rollers 25, 26. And, guide rollers 29, 30 for guiding the sheet body 24 are installed on both end parts of the board-like body 22 resiliently displaceably to approach and separate from the board-like body 22. These guide rollers are energized in the parting direction from the board-like body 22 by means of springs 31, 32 provided on brackets 27, 28. Further, rotary- body locking means 54, 55 consisting of a brake shoe 53, a driving lever 47, and a brake drum, etc. are provided to prevent the wind-up rollers 25, 26 from rotating in the rewinding direction when the travel of the sheet body 24 is stopped, while releasing the rotation preventing force when the sheet body is traveling. As a result, the noise of the traveling device can be reduced.

IPC: H03F3/30
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To secure an output voltage as high as possible even from a low voltage power supply and to reduce the current consumption. SOLUTION: An input signal to a 3rd npn transistor(TR) 5 being an input stage of an output amplifier circuit 80 is increased, a current is supplied to a load resistor 8 from the TR 5 via a resistor 3, and a maximum output current (-I0max ) is expressed as -I0max =Ib5 ×hfe, where Ib5 is a base current of the TR 5 and hfe is a current amplification factor so that the current consumption in the TR 5 is set to 1/hfe of the output current. On the other hand, when an input signal to the TR 5 is small and the TR 5 is turned off, a positive maximum current is supplied to the load resistor 8 via a TR 2, and resistors 3, 4, resulting that the maximum output amplitude is adjusted different from a conventional output circuit by properly selecting the resistance of the resistor 3.

Abstract: PURPOSE:To obtain a drive circuit for optical semiconductor in which the response speed of an optical output is quickened, by decreasing the trailing time of the optical output of the optical semiconductor. CONSTITUTION:In a transistor (TR)1 for high speed switching, its input and output terminals 2, 4 are connected with a diode 8 with the inverted polarity as a light emitting diode 5 to be driven viewed from the input terminal 2. When the TR1 is switched from off to on and the TR1 of sufficiently high speed type is driven with a sufficient base current, the leading time of optical output is reduced. When the TR1 is set on from off, even if the TR1 is turend off in high speed, since the diode 5 is subjected to reduce the voltage to 0V via the diode 8 and an internal resistor 9, charges stored in the diode 5 are picked up via the diode 8 and the internal resistor 9 and the trailing time of the optical output of the diode 5 is decreased.
