Title: Magnetic recording medium
Inventor: KITAGAMI OSAMU
IPC: G11B5/66
Filed: 1987-04-06
Abstract: PURPOSE:To improve the coercive force of a magnetic film by constituting a nonmagnetic underlying layer of a material having a specific heat conductivity and constituting the ferromagnetic layer of a ferromagnetic metal contg. Cr. CONSTITUTION:The nonmagnetic underlying layer 2 is constituted of the material of which the heat conductivity exhibits <=30W/m.k in a 20-300 deg.C range and the ferromagnetic layer 3 is formed of the ferromagnetic metal contg. Cr. The grain size of the particles constituting the underlying layer 2 is not particularly limited and is preferably relatively larger than in the case of using other materials. The grain size of the particles constituting the underlying layer 2, stated as a mere guide line, is generally preferably in an about 100-500Angstrom  range. The size of the ferromagnetic metal particles grown and formed thereon is relatively larger as the grain size of the particles constituting the ferromagnetic metal 2 is large. The remarkable improvement in the coercive force of the recording magnetic layer is thereby attained.

Title: Solenoid valve control circuit
Inventor: KANEKO YOSHIYUKI
IPC: F16K31/06
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the failure in operation of a solenoid by comprising an accumulation amount detecting means for detecting an accumulation amount of an accumulator, and forbidding the energization of the solenoid when the output of this accumulation amount detecting means is below a predetermined value. SOLUTION: The voltage necessary for the close energization without recharging after the termination of the open energization is determined on the basis of the capacity of a capacitor 4 and the resistance value of a solenoid 10. The open energization is forbidden until the predetermined voltage is obtained. Whereby the voltage of the capacitor 4 is sufficient in the open energization, and the close energization can be executed with the remained charge of the capacitor 4 even when the close energization is required immediately after the open energization. That is, an open state is not continued regardless of a time when a battery is demounted.  In a case when the accumulation amount is not satisfied, the solenoid is not energized, so that the lowering of the accumulation amount caused by the frequent energization of solenoid can be prevented, which prevents the failure in operation of the solenoid 10.
