Inventor: DENISU GUREN UERIIGAN
IPC: B29C48/05
Filed: 1984-11-09
Abstract: An article is provided comprising a plurality of straight spaced parallel extruded elements separated by a regularly undulated extruded element having an aspect ratio of at least about two, with undulations having opposed apexes on either side thereof, with apexes on one side of the undulated element being bonded to one of the parallel extruded elements and the apexes on the other side of the undulated element being bonded to the other of said parallel extruded elements.

Title: Semiconductor device and its manufacture
Inventor: SHIGETA JUNJI
IPC: H01L21/331
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To accurately arrange a front electrode and a back electrode in the positions which face each other, by making the sectional shape of a back electrode formed on the back of a semiconductor be in a reverse T shape. SOLUTION: In this manufacturing method, an electric field transistor having gate electrodes which are position-aligned on the surface and the back of a channel layer 3 with high precision, respectively, can be manufactured with high yield, and the formation of an integrated circuit is also enabled.

Title: Protection circuit
Inventor: FUJITA MASAYA
IPC: H02H3/24
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To protect a horizontal deflection output circuit, in the case of reaching the unexpected state of power interruption, such as service interruption in a television receiver. SOLUTION: A detector 3 for detecting the voltage of a power line 2 for a pulse generating means 1A for horizontal deflection is installed. The detector 3 detects the voltage drop at a level slightly higher than the voltage, where the oscillation of horizontal deflection pulses stop, at the voltage of the power line 2. When the voltage drop is detected, power supply from a power supply 6 to a horizontal-deflection output circuit 4 is interrupted by a power interruption means 5. By doing so, operation under unstable oscillation state can be avoided, and the horizontal-deflection output circuit can be protected surely.

Abstract: PROBLEM TO BE SOLVED: To suppress a noise generated from the front edge part of each blade, by arranging a boundary layer stabilizing blade on the negative pressure surface of a plurality of blades, so that the peripheral side surface of the boss of the boundary layer stabilizing blade is directed to the upstream side of a relative inflow flow against the relative inflow flow, and the peripheral side surface of each blade is directed to the downstream side of the relative inflow flow. SOLUTION: A boundary layer stabilizing blade 26 is arranged on the negative pressure surface of a plurality of blades 21, so that a side surface on the peripheral side of a boss 22 is directed to the upstream side of a relative inflow flow 23W and the side surface on the peripheral side of each blade 21 is directed to the downstream side of the relative inflow flow 23, respectively by the boundary layer stabilizing blade 26 having a steering angle β against the relative inflow flow 23W.  Thus, in the part of the boundary layer stabilizing blade 26, static pressure on an outside surface 26 side is lowered in comparison with an inside surface 26f side, and draft is collided with the boundary layer stabilizing blade 26 so as to get over the boundary layer stabilizing blade 26, thereby the drift is turned into a flow to roll in a direction blowing to the negative pressure surface 21n of each of the blade 21. Hereby, the increase of a noise generated from the front edge part of the blade 21 can be suppressed.

IPC: G11B5/66
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To obtain a recording magnetic film which has good high-density recording characteristics by thermal magnetic recording method and large saturation magnetization at room temp., and therefore, which enables reproduction with high resolution and high output by a magnetic sensor such as an MR head. SOLUTION: At least two layers of magnetic layers including a first magnetic layer 21 having optimized recording characteristics for thermal magnetic recording method and a second magnetic layer 22 having optimized reproducing characteristics by increasing the saturation magnetization at room temp. are used in the medium.

The magnetic layers are formed such that at the recording temp., the magnetic layer adjacent to the first magnetic layer 21 loses its magnetization and that the recording characteristics of the first magnetic layer are not influenced by the second magnetic layer 22.  Thereby, in this magnetic recording medium in which the magnetic layer relating to the recording characteristics and the magnetic layer relating to the reproducing characteristics are separately designed, both of thermal magnetic recording method and reproducing method with a magnetic sensor are possible and a storage system which enables a high-density recording and reproducing by using the advantages of the both methods can be realized.
