Title: Memory control device
Inventor: AIZAWA KAZUYUKI
IPC: G06F13/38
Filed: 1989-12-14
Abstract: PURPOSE:To improve the efficiency of data transfer by attaining direct data transfer in the case of executing data transfer between a peripheral device and a memory under the control of a CPU. CONSTITUTION:Data transfer between the CPU 10 and the memory 11 is inhibited by validating a transfer switching control signal A15 to execute data transfer between the memory 11 and the peripheral device 12 without using the CPU 10. When the signal A15 is invalidated, normal data transfer between the CPU 10 and the memory 11 can be normally executed. Since it is unnecessary to temporarily storing data in the internal memory of the CPU 10 at the time of executing data transfer between the memory 11 and the peripheral device 12, data transfer can be rapidly executed. In addition, the use of complex constitution such as a DMA type DMA controller is unnecessary.

Filed: 1994-12-26
Abstract: PURPOSE: To prevent the deformation of a shim and the tilt of a piston due to the entering of the piston into the slits of the shim, by providing the shim, having the slits radially arranged, between a disk pad and the piston. CONSTITUTION: An outer side shim 7 is locked to the back plate 4b of an inner side disk pad 4 by folding the upper and lower claws 7a and 7b of the shim 7 to be engaged with the back plate 4b, and consequently abuts on a piston 3. First radial slits 7c are provided on the outer side shim 7, and grease is enclosed in the first slits 7c for preventing the noise sounding of the disk pad at the time of braking. Since the first slits 7c are radially arranged, the end part peripheral part of the piston 3 and the first slits 7c are orthogonal each other, even when the piston 3 abuts on the outer side shime 7, consequently, the peripheral part of the piston 3 is inhibited to overlap with the first slits 7c over a long distance. As a result, the sinking of the peripheral part of the piston 3 into the slits 7c can be eliminated.
