Title: Slider, transducer support and magnetic memory
Inventor: TAKEUCHI YOSHINORI
IPC: G11B21/21
Filed: 1993-05-18
Abstract: PURPOSE:To possible a slider in which the floating amount is limited stably by providing a surface having a specific level difference at the gas inlet end on the gas bearing surface of the slider. CONSTITUTION:A slider 12 is floated by the pressure of gas flowing between the gas bearing surface 13 and a rotating memory medium. The gas bearing surface 13 is formed out of a surface 14 having a level difference 16 with respect to the surface 13 and the remaining surface part (face) 15 of the surface 13 for generating positive pressure. The gas flow intrudes onto the surface 14 of the slide 12 to cause pressure rise, but the pressure decreases as the velocity of gas flow increases. Furthermore, the gas flow intruded through the level difference part 16 onto the surface 15 causes continuous pressure increase regardless of the velocity thereof. On the other hand, the gas flow applied the slider 12 with a load increasing with the velocity thus restraining the slider 12 from floating. The pressure and the load are related to the level difference at the part 16 and when the level difference between the surfaces 14, 15 is set at 700nm or less, a slider having stably limited floating amount can be obtained.

Title: Speech input device
Inventor: HIRAYAMA KENICHI
IPC: G10L15/28
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To provide a speech input device to input a speech so that it is not heard by a third party in such a situation as the third party may hear it at an automatic cash dispenser, etc. SOLUTION: A video camera 11 reads a pattern of the eyes 2a of an utterer 2. An iris code generation part 12 extracts features of an iris pattern and generates iris data. The collation part 13 collates the iris data of the registered utterer in registration data base 20 to identify the utterer 2. A musical sound signal generation part 30 retrieves the speech data of the utterer 2 from the registered data base 20 and generates a musical sound signal to counteract the speech of the utterer 2 based on the speech data, to output it to a third party 3 from an acoustic output part 40. Thus, it becomes difficult for the third party 3 to recognize the speech of the utterer 2 by hearing.  On the other hand, the speech of the utterer 2 is inputted to an acoustic input part 50 with the musical sound from the acoustic output part 40 synthesized, but the musical sound component is suppressed by a musical sound signal suppression part 60, and has no influence on the speech recognition.

IPC: H01L21/302
Filed: 1991-05-21
Abstract: PURPOSE:To enable a high-density plasma to be generated highly uniformly and a semiconductor substrate to be etched at a high speed and highly uniformly by specifying a magnetic field inclination value in the axial direction of a magnetic field which is formed within an electron cyclotron resonance region. CONSTITUTION:A wide resonance region is formed at a magnetic field which is formed by single excitation of a solenoid coil 4 lacks uniformity. However, when an excitation current value of an auxiliary coil 9 is increased for this magnetic field. a weak mirror magnetic field is formed between the solenoid 4 and the auxiliary coil 9 since there is a gap B. Therefore. as the excitation current is increased, a central portion of a reaction chamber 1 is affected and an ECR region spreads gradually. Then, a magnetic field inclination value of the magnetic field is specified to 50 Gauss/cm or less in the axial direction within an electron cyclotron resonance region and a difference between maximum and minimum values of this magnetic field inclination is formed to be 10 Gauss/cm or less by controlling the excitation current, thus enabling an etching speed to be improved and uniformity to be improved.

Title: Printed wiring board
Inventor: ITO KENICHI
IPC: H05K1/02
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To effectively lower an radiated noise from the printed wiring hoard itself basically by reducing the electromagnetic radiation noise from an electronic device without the use of an expensive noise prevention component. SOLUTION: A signal layer 12, an earth layer 13, and a power layer 14 having many power patterns, and a signal layer 15 having many earth patterns, are laminated into mutilayer structure in the order. The thickness t1 of the both side layers 17 and 18 are formed thinner than the thickness t0 of the central board layer 16, and the stray capacitance on the both side layers 17 and 18 is increased to provide double decreasing effect on the radiation noise. At the same time, the opposing rate of 10% or more between the power pattern of each signal layer 12 and 15 and the earth pattern makes it possible to secure the noise reduction effect required. This eliminates an extra component, making it possible to achieve noise suppression at a low cost.
