Title: Tundish injection pipe
Inventor: SAITO KOJI
IPC: B22D11/10
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent an injection pipe body from breakage and detachment during using the pipe so as to use the injection pipe many times by forming a light-weight castable layer on the inner surface of the injection pipe composed of a refractory. SOLUTION: In this tundish injection pipe, a light-weight castable layer 2 is formed on an inner surface of an injection pipe body 1 composed of refractory. While the tundish injection pipe is being used, a base metal adhered at more than a specific thickness (weight) is peeled off together with a light-weight castable of required thickness. Also, during usage, the adhered base metal can be easily removed together with the light weight castable of required thickness. Furthermore, the inner face of the injection pipe body is formed into a taper in a way that the diameter is gradually expanded from the upper part to the lower part, so as to facilitate peeling-off of the adhered base metal during usage and removal of the adhered base metal after usage. In this case, it is preferable that an angle θ of the taper is 1-7 deg..

Title: Magnetic head and its production
Inventor: INO KAZUO
IPC: G11B5/187
Filed: 1989-07-12
Abstract: PURPOSE:To maintain the life of a head and to reduce damage on the sliding surface of the head being in contact with a medium to prevent deterioration of traveling property of the medium by finishing the head surface on which a medium enters in sliding contact to have two curved areas in a manner that the first area surrounds the second area and the first area has larger radii of curvature in the traveling direction of the medium and the perpendicular direction than those of the second area. CONSTITUTION:The contact surface of the head on which a recording medium slides consists of two areas, the first area surrounds the second area 12 which includes the magnetic gap and is finished to have a curved surface with radii of curvature in the traveling direction and the perpendicular direction to it. The first contact surface area 11 is also finished in a curved surface with larger radii both in the traveling direction and the perpendicular direction than those of the second contact surface area 12. When the magnetic gap 5 decreases its depth, the contacting area of the surface which contacts to the medium increases while maintaining the traveling property of the medium, and becomes almost constant at a certain area. Thereby, the traveling property of the medium can be maintained in good state without decreaseing the life of a head.

Title: Method and device for testing storage medium by using dynamic threshold margin
Inventor: DAARIRU EMU SHIRAKII
IPC: G11B21/21
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a storage medium testing device using a dynamic threshold margin. SOLUTION: An output signal is generated by a glide head 202 to be transmitted to an amplifier 204. The output terminal of the amplifier 204 is coupled to a DC converter 206, which subjects the amplified output from the amplifier 204 to a DC conversion. This signal subjected to the DC conversion is supplied to a differential amplifier 208 together with a reference signal from a reference voltage source 210. The signal generated by the amplifier 208 is used in order to dynamically control the gain and/or offset of the amplifier 204. Consequently, the amplifier 204 generates a dynamically amplified output signal.  A comparator 214 compares the dynamically amplified signal from the amplifier 204 with the threshold level signal from a threshold level generator 216 to generate a proper logical signal indicating whether the dynamically amplified output signal exceeds the threshold level or not.

Filed: 1990-07-09
Abstract: PURPOSE:To prevent operation of parasitic bipolar transistor and improve avalanche resistance by forming, on a semiconductor layer, a fifth region of a second conductivity type which is deeper than a third region and has high impurity concentration and connecting this fifth region to a main electrode. CONSTITUTION:On the occasion of forming a P<+> well diffused region 4 of a low resistance of an ordinary cell, a P<+> type diffused region 10 having an area wider than four times that of the ultra-miniaturized ordinary cell is formed and it is arranged in the external circumference of the ordinary cell having the P<-> type diffused region 3 or in the vicinity of a pad of a source electrode 8, in order to reduce invalid area of a silicon substrate. Since the area is wide, the P<+> type diffused region 10 is diffused deeper than the P<+> type diffused region 4, with a large volume of impurity used as a diffusion source. Therefore, an avalanche current generated at the transition time flows into a diode formed by an N<-> type drain region 1 and the P<+> type diffused region 10 but no not flow easily into the P+ type diffused region 4 or into a P-type region 3. Accordingly, operation of a parasitic transistor consisting of an N<+> type source region 5, the P<-> type channel diffused region 3 and the N<-> type drain region 1 is suppressed and breakdown does not occur. A source electrode 8 is in contact with the P<+> type region 10 and an avalanche current flows into this region.
