Title: Tape driver
Inventor: MIZUGUCHI NOBUAKI
IPC: B65H23/185
Filed: 1982-12-03
Abstract: PURPOSE:To prevent the damage at the end of a tape and to perform a random access at a high speed by providing a revolution detector which produces a signal in response to the number of revolutions of a supply reel, and a control voltage generator which varies the terminal voltage of a reel motor by comparing the signal of the revolution detector with a reference signal set previously. CONSTITUTION:A control voltage generator 3 applies a fixed level of voltage V0 to a reel motor 4 until it receives a command signal of a comparator 2. Then the motor 4 runs with constant revolutions, and a revolution detector 1 produces the voltage proportional to the number of revolutions of a supply reel. The reference voltage of the comparator 2 is set at the level of the voltage which is delivered from the detector 1 at a place near the end of a tape. Therefore, the comparator 2 works when the number of revolutions of the supply reel reaches the set value. A control voltage generator 3 applies the voltage V half of the V0, for example, that is previously set to the motor 4 after receiving once a command signal from the comparator 2. As a result, the number of take-up revolutions of a reel motor 4 is decreased, and accordingly the number of revolutions of the supply reel is decreased, thus the damage produced at the end of a tape is suppressed.

Abstract: PURPOSE:To enable formation of a coated film having an optional thickness on the inside wall surface of a pipe by reducing the pressure in the pipe to suck the high-viscosity lining material into the pipe, inserting a pig made of an elastic material into the pipe and pressing and moving the lining material forward via the pig. CONSTITUTION:The pressure in the pipe 1 to be treated is reduced to suck the high-viscosity lining material 5 into the pipe so that the lining material 5 is accumulated at the inlet end of the pipe 1. The pig 6 made of the elastic material is inserted behind the lining material 5 to generate a pressure difference between the space behind the pig 6 and the space before the lining material 5, by which the lining material 5 and the pig 6 are integrally moved toward the outlet end side of the pipe 1. The need for cleaning the lining material supplying system at every end of the supply of the lining material is eliminated and the efficiency of the lining operation is extremely improved. The coated film of an arbitrary thickness between 0.5-4mm is formable on the inside wall surface of the pipe by changing the moving speed of the pig.

Title: Optical transmitter
Inventor: KATAYAMA HIROSHI
IPC: H04B10/07
Filed: 1986-09-09
Abstract: PURPOSE:To obtain an high-speed, stable optical transmitter of simple constitution by providing the optical transmitter with negative feedback by a temperature-electricity transducing means coupled thermally with a light emitting element and an amplifier. CONSTITUTION:A signal inputted to a main amplifier A1 is amplified and part of its output current is supplied to the light emitting element LED through a resistor R2 while the remainder is inputted to an error amplifier A2 through a resistor R1. A temperature compensating amplifier A3 is applied with a voltage having a proper value from a variable voltage source. When the temperature of the light emitting element LED rises, a current flowing through the temperature-electricity converting element lo coupled thermally therewith increases, so a voltage applied to the inverted input terminal of the temperature compensating amplifier A3 rises and the output voltage falls. A voltage applied to the uninverted input terminal of an error amplifier A2, therefore, falls and the output of the controlled main amplifier A1 is reduced to decrease the output of the light emitting element LED. Consequently, the optical transmitter is stabilized on the whole.
