Title: Magnetic recording medium
Inventor: MIYAKE AKIRA
IPC: C09D5/23
Filed: 1978-12-20
Abstract: PURPOSE: To obtain a magnetic recording medium featuring the reduced deterioration with aging for the magnetic properties and high dispersion of the magnetic powder by forming the silicone oil film on the surface of the magnetic powder composed mainly of iron and then coating the magnetic powder on the substrate along with the urethane resin.  
     CONSTITUTION: The magnetic powder is wetted with the organic solvent containing the silicone oil (such as the dimethyl polysiloxane, KF-96 manufactured by SHINETSU KAGAKU KOGYO K.K.) and then heated at about 350°C or less and in the inorganic gas or reducing gas atmosphere to be dried with volatilization of the solvent. Thus the silicone oil film is formed on the surface of the magnetic powder (preferably the film sticking amount of 0.1W10 parts by weight to the magnetic powder of 100 parts by weight). Then the film magnetic powder is coated on the substrate along with the thermoplastic polyurethane resin containing no free isocyanate group. Thus the magnetic recording medium is obtained.

Title: Pressure sensitive type valve drive mechanism and pressure control valve of refrigeration cycle using the same mechanism
Inventor: SASAKI SATOSHI
IPC: F16K31/42
Filed: 1989-06-23
Abstract: PURPOSE:To miniaturize the shape of a pressure response member and reduce production cost by a method wherein an applied voltage to an electromagnetic solenoid is changed and the push pressure (valve closing force) of a return spring against the pressure response member to a valve seat is adjusted. CONSTITUTION:When an electromagnetic solenoid 21 is in no conductive state, the spring force (push load) of a return spring 20 applied on a valve body 15 through a plunger 18 becomes the maximum and therefore, the body 15 comes in contact with the valve seat 13 of an orifice 14 with pressure to close the orifice 14. As compared with this, when a voltage is applied to the solenoid 21, a magnetic attraction force against the force of the spring 20 acts on the plunger 18 and the pushing load (valve closing force) acting on the body 15 of the plunger 18 is weakened. Accordingly, when the applied voltage to the solenoid is controlled electrically, the valve opening force necessary for the body 15, that is, the aforesaid valve opening force for a pressure response member 2 acting on the body 15 can be controlled optionally. Thereby, miniaturization and the reduction of production cost can be carried out.

The signal is then inputted together with the floating threshold signal SL past an LPF 34 to a comparator 35 via an absolute value circuit 33 and is binarized. This signal is passed through a decision circuit 37 by which the dark part of the stripe patterns is erased and only the bad is displayed; in addition, an NG signal is outputted as a defect part when the area of the bad is above the prescribed value in a defect part extracting circuit 52. The inspection is thereby exactly and automatically executed.
