Title: Heat exchanger
Inventor: KISHIMOTO TAKASHI
IPC: F28F1/30
Filed: 1994-03-07
Abstract: PURPOSE:To efficiently supply the air to a blower fan by setting directions of a surface of fins to two types or more as a whole fin, altering an air ventilating direction to two or more types, and feeding it forward to a rotating direction of the fan. CONSTITUTION:When a blower fan 2 is driven, the air is introduced into an air conditioner body 3 through a suction grill 3a as indicated by arrows of numerals 42, 43, and diffused to a heat exchanger 1. This air is heat exchanged with refrigerant flowing in a channel of a flat tube 21, then altered in its flowing direction by fins 22u, 22d to arrows of numerals 42a, 43a, and diffused from a diffusing grill 3b to an exterior by the fan 2. Accordingly, a flow of the air fed to an upper part of the fan 2 becomes forward to a rotating direction 2a of the fan 2, and hence the air efficiently flows, thereby improving its performance.

Title: Phase comparing circuit
Inventor: OKABE YUKIO
IPC: G01R25/00
Filed: 1981-03-13
Abstract: PURPOSE:To exercise stable phase comparison control even during a period when a phase difference between two input signals is extremely large, by performing switching to an output voltage similar to that during phase coincidence if the input signals are extremely out of phase. CONSTITUTION:A horizontal synchronizing pulse, which contains a jitter, extracted by a synchronizing signal separating circuit 5 on the basis of a signal reproduced from a disk 2 with a reproducing stylus 1 is compared with a phase comparator with a horizontal synchronizing signal, which contains no jitter, outputted by a synchronizing signal generator 8 according to a reproduced tracking signal. On the basis of the resulting comparison voltage, the tracking of the stylus 1 is controlled through an arm stretcher 10. Once this generator 8 generates a vertical blanking pulse, a switch 11 is changed over to apply the stretcher 10 with a cntrol voltage similar to that during phase coincidence from a power source 12. Therefore, even during a vertical flyback period when two comparison inputs are greatly out of a phase, a failure in control, etc., never occurs and stable control is exercised.

Title: Thin-film magnetic head
Inventor: NAKAMURA KAZUO
IPC: G11B5/11
Filed: 1990-02-16
Abstract: PURPOSE:To obtain the shielded MR head of a narrow gap and to allow the reproduction of high-density signals by providing a means for impressing DC currents, the directions of which are in the transverse direction of a track and are opposite from each other between a pair of shielding layers to these shielding layers and disposing only the MR element thin film and the necessary insulating film in the gap part between the shields. CONSTITUTION:The shielding layers 2 electrically insulate and crimp the MR element thin film 1 and one end of the MR element thin film 1 and the shielding layer 2 is exposed to the head sliding surface. The current impressing means impresses the currents, the directions of which are in the transverse direction of the track and are opposite from each other between the shielding layers 2 to the shielding layers 2. The DC magnetic field of the direction where the MR element is required to be biased is generated in the gap 5 by the currents impressed to the shielding layers 2, by which the MR element is adequately biased. Since there is no need for disposing a bias impressing means in the gap 5, the narrowing of the gap is possible. The MR element is effectively biased in this way and the improvement in the reproducing efficiency of the head is made.

Title: Gas insulated transformer
Inventor: INOUE TAMOTSU
IPC: H01F27/18
Filed: 1985-02-27
Abstract: PURPOSE:To increase the reliability of a cooling system, to prolong the life of the title transformer as well as to reduce the suspension of operation of the transformer by a method wherein an air pump. That works as a refrigerant circulating pump as well as compressed air in the circulating system of a cooling system. CONSTITUTION:An air pump 20 having compressed air as the source of power, an air pipe 21 wherein compressed air which is the source of power of a refrigerant circulating pump is passed through, and a compressor 22 which produces compressed air are provided, and the power sources of the compressor 22 and a condenser are formed independently. Consequently, as an auxiliary pump is provided on the compressor, the air pump 20 does not stop immediately even when the pump of the compressor 22 stops by the suspension of electric power of the auxiliary power source. As a transformer can be stopped while its load value and heating power are being reduced without stopping the transformer immediately, the thermal deterioration of the insulator can be prevented. Also, as the compressor 22 and the condenser are formed on separate system, thermal breakdown is not generated on the transformer immediately even when either of the power source is in trouble, and as the condenser and the refrigerant circulating pump have the independent source of power for electricity and air, the reliability of the title transformer can be enhanced.

Title: Deflection yoke
Inventor: KUWABARA YASUNAGA
IPC: H01J29/76
Filed: 1988-02-18
Abstract: PURPOSE:To make the distribution of magnetic field produced by a deflection yoke be coincident with a given distribution by defining two coil segments produced through division of a coil in least two halves and connected in parallel to each other, to be one side coil and forming a pair of horizontal or vertical deflection coil with those coil segments. CONSTITUTION:An inner coil 1 and an outer coil 2 produced by dividing one side coil of a saddle type coil into two halves are wired in a parallel connection. Deflecting currents flowing through the inner coil 1 and the outer coil 2 are inversely proportional to the inductance of the inner coil 1 and the outer coil 2. Thus, if it is desired, for example, that the inner coil produces an extreme barrel-type magnetic field and the outer coil produces an extreme pin cushion- type magnetic field, the spacing 3 between the inner coil 1 and the outer coil 2 is increased and the inductance of the outer coil 2 is made larger than that of the inner coil 1, thereby the coil distribution can be made to be nearly conventional cos theta distribution. Thus, taking the stability of production of deflection coils into account, a given magnetic field distribution can be freely produced.

Title: Magnetic head suspension
Inventor: FUJINO NAOHIKO
IPC: G11B21/21
Filed: 1991-03-04
Abstract: PURPOSE:To suppress deterioration of a lubricating effect attending upon contact sliding and to prevent a head part from flawing by providing a prescribed expansion part to an intermediate part of the magnetic head suspension. CONSTITUTION:The expansion part 15 bent in a waveform is provided to a load beam 11 in the intermediate part of the magnetic head suspension 10, so as to enable the displacement of the magnetic head suspension 10 in the lengthwise direction against a load received by the magnetic head due to contact sliding with a magnetic disk. By this method, with regard to a sliding track on the magnetic disk by the magnetic head, the magnetic head is displaced in the sliding direction by expanding and contracting the expansion part 15 by an amt. proportionate to friction force owing to the friction force to be generated at the time of sliding. Consequently, an apparent sliding track becomes wider than the conventional pattern, and damage per unit track to be given to the magnetic disk is small, and hence the deterioration of the lubricating effect is suppressed.
