Title: Magnetic head
Inventor: YOSHIOKA NOBUAKI
IPC: G11B21/21
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic head by which the starting torque of a magnetic disk medium is increased by a method wherein a lubricant which is stuck to the rear end face of the magnetic head creeps between the floating face of the magnetic head and the surface of the magnetic disk medium so as to bring both into close contact. SOLUTION: From a floating face which is formed on the face of a magnetic head 1 facing to a magnetic disk medium, a groove 18 is formed in the floating face in a wide width part 17 to the rear end part of a center rail 11 so formed as to be continuous with the rear end face of the magnetic head 1. The floating face of the center rail 11 is divided by the groove 18. A lubricant which is stuck to the rear end face 1a of the magnetic head 1 creeps between the floating face and the face of the magnetic disk medium, and it is spread along the floating face due to a capillary phenomenon.  However, since the floating face is divided by the groove 18, the lubricant is not spread so as to go over the grove 18, Thereby, an area in which the lubricant is interposed between the magnetic head 1 and the magnetic disk medium is small, and it is possible to restrain an increase in a close contact force between the magnetic head 1 and the magnetic disk medium.

Title: Method and device for diminishing nasty smell
Inventor: KURAMOCHI SHIRO
IPC: A61L9/03
Filed: 1991-12-12
Abstract: PURPOSE:To diminish a nasty smell by dropping down oils and fats by a few drops onto a heated metallic plate, decomposing a part or the whole of the oils and fats, and floating fumes generated by the decomposition in the air in which the nasty smell is contained. CONSTITUTION:When a heating implement 10 is heated, a metallic plate 20 placed thereon is heated to >=250 deg.C. In such a state, by opening an outlet 31, oil contained in a vessel 30 is dropped down intermittently onto the metallic plate 20 as liquid drops from the lower end of a tube 32. The dropped liquid drops of oil are heated immediately on the metallic plate 20, decomposed and become smoke, and volatilize. When this method is executed in a cowshed, a nasty smell is diminished. In such a way, since the nasty smell is diminished, milking from a milking cow is facilitated in the cowshed. Also, since the nasty smell is eliminated, a fly and a mosquito come not to exist in the cowshed. Accordingly, the living environment of a milking cow is improved, and improvement of the production quantity of milk is expected.

Title: Solenoid valve and brake control device provided with solenoid valve
Inventor: KAMIYA MASAHIKO
IPC: F16K31/06
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a solenoid valve and a brake control device that can prevent the generation of vibration and noise of a brake pedal and improve a braking feeling. SOLUTION: Main seat cross-sectional area in a main communicating passage 57 is set larger than auxiliary seat cross-sectional area A2 in a restriction communicating passage 57. An auxiliary valve element 56 is energized by a return spring 62 in a direction of being spaced from a stopper 42, but the energizing force (Fsp 1) of the return spring 62 is set larger than the energizing force (Fsp 2) of an auxiliary spring 59. Attracting force is generated to a main valve element 54 and the auxiliary valve element 56 by electromagnetic force generated in the case of applying a current to a solenoid 40, but this attracting force is so set that attracting force (Fcoil 1) of the auxiliary valve element 56 is 75% of the whole attracting force and that the attracting force (Focil 2) of the main valve element 54 is 25% of the whole attracting force.  The half opened state of a solenoid valve can therefore be realized in the case of performing pressure control at the time of depressing a brake pedal 1.
