Title: Magnetic head slider and magnetic disk loading the same
Inventor: TOKUYAMA MIKIO
IPC: G11B21/21
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a slider which does not damage a disk with the front edge thereof even during CSS or when a magnetic slider in the floating condition is in contact with a rotating magnetic disk and also results in drop of floating due to reduction of air pressure. SOLUTION: A floating pad 10 of a magnetic head slider 11 is formed of a stepped surface 12 having a small stepped area and a flat surface 13 and a very small projected area is formed at the stepped surface 12. Height of projected area is higher than or identical to the height of stepped area. Because of a very small projected area, the slider does not easily rotate with inclination to the front side and the front edge of stepped surface does not damage the disk surface. Moreover, variation of floating amount can be reduced by a negative pressure generated in the backward direction of the very small projected area. Thereby, highly reliable large capacity magnetic disk recording apparatus can be provided.

Title: Water feed heater drain controller
Inventor: HAYASHIDA KOICHI
IPC: F22D1/32
Filed: 1989-05-11
Abstract: PURPOSE:To stabilize drain water level control by providing a control valve failure detector in each water feed heater and allowing the controller to enforcedly control a drain water level control valve of the other system of the water feed heater at the time of failure detection of the drain water level control valve in the above device in a steam turbine plant. CONSTITUTION:For example, in the case where a control valve 11a, fails to open wholly, the wholly opened signal is detected by a control valve failure detector 13a to input in a controller 10a2. The control valve 11a2 is wholly closed on the basis of this signal. At this time, water feed heaters 3b, 3c and four control valves 11a1-11c2 are allowed to perform normal control to cope with the failure of the control valve 11a1 with the aid of only operation of the control valve 11a2. By this constitution, drain water level control can be stabilized and damage caused by flow elasticity movement of heat exchanger tubes can be prevented.

Title: Method for formatting reload-type compact disk
Inventor: SIMS ROBERT J III
IPC: G11B7/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To speed up partial formatting and incremental recording of a reload- type compact disk. SOLUTION: In an incremental format process for formatting a physical data track of a disk, a drive partially formats the disk to include a lead-in area 300, a limited program area 302 and a lead-out area 304. Then, the drive formats an additional frame exceeding the lead-out area in an off-line process. With the utilization of a gap 305 between the existing lead-out area 304 and a newly formatted frame 306, the drive aligns a succeeding fixed length packet with a fixed length packet written before. When the whole track is filled with formatted frames, a host computer overwrites the old lead-out area 304 and fills the gap 305 with a new null data frame, thereby forming a fresh program area 310.

Abstract: PURPOSE: To improve the connecting workability of circuit boards to each other and to improve the reliability of connection. CONSTITUTION: Anisotropic conductive adhesives 6 consisting of insulatable adhesive layers 8 and conductive particulates 7 have a sheet shape prior to curing and are held in this state between circuits 5 for connection and copper foil patterns 2. The circuit boards are then subjected to heating and pressurizing by a heater tool from the upper of the circuit board, by which the anisotropic conductive adhesives 6 are cured and the conductive particulates 7 are brought into contact with both of the circuits 5 for connection and the copper foil patterns 2 and are further strongly pressed to the circuits 5 for connection until finally depressive holes corresponding to the shapes of the conductive particulates are formed on the circuits 5 for connection.  The parallelism of the heater tool on the circuit parts to be pressed is merely necessitated to be relatively gentle and since the surface flatness of the heater tool itself is merely necessitated to be relatively gentle, the working difficulty is low and, therefore, the reduction of a manufacturing cost is made possible.

Abstract: PURPOSE:To exactly derive the embedded position and its depth by measuring a rotation angle of the direction of a coil shaft of a transmitting or receiving coil when a measured value of an inducted current generated in a metallic long-size object. CONSTITUTION:A pulse current is allowed to flow to a transmitting coil 13A through a switch SW1 from a transmitter 17, and a metallic long-size object 1 is allowed to generate an induced current I. As for such a current I, a pulse current is induced therein, amplified by a detection amplifier 23 and received by a radio receiver 19 by a pulse wave from a radio transmitter 24. Subsequently, when a motor 15A is rotated through an SW2 from a power source 18 and a coil shaft of the coil 13A is turned to the long-size object 1, the current I generated therein comes to '0'. In the same way, when the switch SW1 is switched to a transmitting coil 13B side, the SW2 of the power source 18 is switched to a motor 15B side thereby, the coil 13B is rotated and the current I is displayed as '0'. In such a way, length between the coils 13A, 13B and angles of both its ends are derived, and an embedded position and depth of the long-size object 1 can be derived.
