Title: Vibration preventing member
Inventor: ITOI TOSHIKI
IPC: G11B33/08
Filed: 1992-10-14
Abstract: PURPOSE:To obtain the excellent vibration preventing member in which the manufacturing cost is reduced more than that of a conventional vibration preventing rubber, excellent elasticity recovery performance is obtained and a temperature characteristic is not almost in existence. CONSTITUTION:The vibration preventing member 2 of a sponge shape is manufactured by injection molding of a thermosetting elastomer inserted between a reception part 1a of a chassis of an optical deck and bosses 3,4 provided to a case of a reproduction device added with a foaming material, and adopts two-layer structure in which a skin layer 2a has a small foaming rate and a core part 2b has a large forming rate. Thus, the spring constant is decreased by reducing the density and the internal loss is increased by the convection of air between foamed air chambers, excellent interruption and absorption of the vibration are attained. Furthermore, the deficient strength of thin thickness is compensated by selecting the foaming rate of the skin layer 2a to be small.

IPC: G11B27/10
Filed: 1994-11-10
Abstract: PURPOSE: To enhance retrieval accuracy and to shorten the retrieval time to a target position. CONSTITUTION: The falling phase (r) of the square wave SMc of a sector mark SM is subjected to phase modulation according to information on disk diameters. This pseudo sector mark signal SM' subjected to the phase modulation is substd. with the original square wave SMc. The sector mark signal SMm after the substitution is recorded in a master disk by using a recorder. A replica optical disk is produced from this master disk. The sector mark signal is read when a focus servo is clocked at the time of reproducing the disk. In which track the sector mark signal exists is known by a difference between the integrated value of the section ab of the square wave SMc subjected to the phase modulation and the integrated value of the section bc. The assigned position is retrieved by utilizing the difference in the detected output value corresponding to this phase difference.

Abstract: PURPOSE:To shorten the CPU cycle by using a differential ECL (emitter coupled logic) bus for the memory access from a CPU and transferring read data of the memory to the CPU through a differential ECL bus which is not subjected to wired OR connection. CONSTITUTION:Since the CPU accesses a memory 46 with a differential address bus 78 independent of an input/output device and takes in read data with the differential data bus 78 independent of the input/output device, the CPU can quickly read out data from the memory 46. Write data to the memory 46 is transferred to the memory 46 through a data bus 34 subjected to wired OR connection but the CPU has a margin of transfer at the time of writing in comparison with read, and therefore, there are no problems. The input/output device accesses the memory 46 through an address bus 47 subjected to wired or connection and a data bus 34 to transfer read data and write data but its operation speed is lower than that of the CPU, therefore, there are no problems. Thus, the CPU can access the memory 46 at high speed.
