Abstract: PURPOSE:To obtain a medium excellent in S/N, MOL and sensitivity, by containing ferromagnetic metallic powder A having >=37m<2>/g of specific surface area and ferromagnetic metallic powder B having <=32m<2>/g in a magnetic layer. CONSTITUTION:It is preferable that the specific surface area of the ferromagnetic metallic powder A is <=45m<2>/g and the specific surface area of the B is >=20m<2>/g.

Title: Wear resistant laminated material and its production
Inventor: KOSUGE SHIGECHIKA
IPC: C23C4/18
Filed: 1990-04-19
Abstract: PURPOSE:To provide a laminated material having large film thickness and superior wear resistance by forming a laminated material by combining an Fe-base base material with a coating material of high speed steel in a method for exerting thermal spraying and then hot isostatic pressing treatment. CONSTITUTION:An Fe-base base material is preheated to >=600 deg.C, and a material composed essentially of high speed steel is thermally sprayed on the surface of this base material by a low-pressure plasma spraying method to form a film of >=3mm thickness. At this time, thermal spraying is carried out under the condition of reduced-pressure atmosphere of <=2Torr partial pressure of oxygen and 20-300Torr total pressure. Then, in order to make the film layer dense, hot isostatic pressing treatment or quench-and-temper or both of them are carried out. The characteristics of wear resistance and hot hardness can sufficiently be produced by using high speed material as thermal spraying material, and further, thermal stress at the time of cooling from the preheating temp. down to room temp. after the completion of thermal spraying can be inhibited because the thermal expansion coefficient of the film is close to that of the base material, and as a result, the adhesive strength between the film and the base material can be increased.

Abstract: PURPOSE:To prevent the malfunction of a phase control loop of a VCO by outputting a detection pulse as a sampling pulse from a unique word detector in a synchronizing clock generator only in case of coincidence of all of (m) bits. CONSTITUTION:Though a timing signal 13 supplied to a terminal station device is outputted in case of coincidence of (m-n) bits or more out of (m) bits of a unique word, a sampling pulse signal 7a is outputted only in case of coincidence of all of (m) bits. Consequently, when a reference burst is lost to input random bit patterns as a receiving burst signal 6, the sampling pulse signal is not outputted. The hold time constant of a sample holding circuit 2 is set to a sufficiently large value to prevent the influence of the code error for a correct unique word input due to noise upon the operation of a phase synchronizing loop.
