IPC: G06F13/38
Filed: 1986-11-28
Abstract: PURPOSE:To improve the efficiency of a buffer and to reduce overhead accompanied with data transfer by properly selecting an initialized buffer capacity. CONSTITUTION:A master processor 1 is connected to a slave processor 2 through a data transfer line 3 to transfer data from the slave processor 2 to the master processor 1. A buffer control part 4 is formed in the master processor 1 and a buffer control part 5 is formed in the slave processor 2. The buffer control part 4 secures the prescribed capacity of the buffer at the time of starting the operation of the system, informs the secured capacity to the slave processor 2 as the initial buffer capacity and then informs a returned buffer capacity to the slave processor 2 every return of the used buffer. The buffer control part 5 stores the informed initial buffer capacity, subtracts the stored buffer capacity every use of the buffer and adds the returned buffer capacity every reception of the returned information to update the buffer capacity. The slave processor 2 transfers data within the stored buffer capacity based on an instruction from the buffer control part 5.

IPC: B65H23/192
Filed: 1988-11-11
Abstract: PURPOSE:To enhance the running stability of both of thick and thin papers by adding necessary tension to paper corresponding to the difference in the thickness of paper. CONSTITUTION:When thin continuous form paper is used, a change-over switch 5 is set to an OFF-state to perform conventional control. When the change-over switch 5 is set to an ON-state in a case using thick paper, an objective value (second objective value) different from that in the case using the thin paper, that is, an objective value capable of applying tension larger than that in the casing using the thin paper is set as the control objective value of the buffer arm 43 of a buffer arm control system 1. In this case, a signal passes through a signal gain increase means 6 and the gain of the angle signal detected by an angle sensor 2 is increased to be sent to a driving control part 3. In this driving control part 3, a signal for controlling the motor speed corresponding to the angle signal increased in its gain is sent to a motor driving means 4. As a result, the speed of a motor 46 is controlled to become the second objective value.

Filed: 1985-12-20
Abstract: PURPOSE:To facilitate highly accurate alignment by employing a light polarized linearly in the direction parallel to be longitudinal direction of slits of LFZP as an irradiating light. CONSTITUTION:A polarization means 10, by which a laser beam which is emitted by a laser 1 and consists of various polarized light components such as circularly polarized lights and linearly polarized lights is polarized linearly to a predetermined direction, is provided.

Abstract: PURPOSE:To obtain a box with no lid which has good strength with respect to the box itself as well as the part with the opening by forming grooves, each cut in a rectangular hollow, in parallel with the sides forming the end and near the opening and by fitting on the end a frame, which has holding pieces capable of being bent inward, with the holding pieces bent inward and setting the holding pieces in the grooves. CONSTITUTION:A frame B is fitted on a box A at its opening. A groove 22 cut in a rectangular hollow is formed in each of the side walls 21 of the box A near the opening. On each side of the frame B a holding piece 33 capable of being bent inward is extended from one end of the main body of the frame 31 with the interposition of a hinge 32. By fitting the frame B on the box A after bending the holding pieces 33 inward the holding pieces 33 can be set in the rectangular grooves 22 formed in the side walls 21 of the box. Therefore, only by fitting the frame on the opening of the box with the holding pieces bent inward the frame which reinforces the opening can be fixed. After the fixation the setting of the holding pieces in the rectangular grooves keeps the frame from coming off.
