IPC: G03G15/26
Filed: 1988-11-22
Abstract: PURPOSE: To hold the tension of an associated belt loop by attaching each floating roller to each of two pairs of first arms and connecting respective ends of the second arms of one pair of levers to corresponding ends of the second ams of the other pair of levers by a tension spring system. CONSTITUTION: When a belt 1 located in a pressure area position bears the slightly low speed of a belt 26. Since the belt 1 is driven by a driving roller 2 at a constant and slightly high speed, a loop on which a floating roller 9 is wound is increased. However, the roller 9 is rotated and lowered together with an arm 19a under a force applied by a spring 24 through a lever 19 so that the tension of the loop is held. The belt 1 slides on a guide roller 4 and travels at invariable speed, so that a loop on which a floating roller 10 is wound is decreased. The roller 10 is rotated together with an arm 21a and raised. The roller 10 holds the tension of members in the loop under a force applied by the spring 24 through a lever 21.

Title: Light transmission circuit
Inventor: MAJIMA MASAO
IPC: H04B10/293
Filed: 1989-11-16
Abstract: PURPOSE:To efficiently transmit a burst signal by setting the bias current of the driving current of a light emitting means so that light output can go to a prescribed value. CONSTITUTION:A semiconductor laser 9 is driven as applying modulation with a rectangular wave at the same transmission speed as that of a signal to be transmitted in advance, and the bias current is increased gradually under digital control. Then, the preset value of the digital control at the bias current by which prescribed light output can be obtained is stored in a memory 3 under the control of a digital APC(Auto Power Control) control part 2. Furthermore, when the transmission of the burst signal is performed, the bias current of a semiconductor laser driving circuit 7 is set by using the preset value stored in the memory 3, and the modulation is applied with the burst signal. In such a way, it is not required to perform the stabilization of the APC to keep the light output of the semiconductor laser 9 constant at every transmission of the burst signal, which enables the transmission of the burst signal to be efficiently performed.

Title: Digital information processor
Inventor: KIMURA KOZO
IPC: G06F9/42
Filed: 1985-12-27
Abstract: PURPOSE:To attain execution of the digital information processing despite the mixture of different bit lengths by using a data access circuit that can transfer data between a main memory and a program counter and a data length designating circuit which controls the data access circuit. CONSTITUTION:When a data access circuit 6 stores data in a main memory 1 from a program counter 2, a data length designating circuit 7 produces the information showing the length of the data to be stored to store it in the memory 1 together with data. When the circuit 6 stores data in the counter 2 from the memory 1, the circuit 7 designates the length of the data to be stored according to the information on the memory 1 and stores data with the designated data length. Therefore it is possible to execute both a certain routine and another routine written by an object code that handles the different bit length from the first routine despite the mixture of both routines when these routines are called out.
