Granted: 1998-04-21
Abstract: A sound absorber has a column shape defined by a hollow,  substantially  cylindrical  wire  frame with  a filler of uniformly distributed fused parallel filaments having high surface area to mass ratio, such as bloomed cellulose acetate.  The sound absorber gives efficient absorption in the articulation frequency range.       A method of manufacture of the sound absorber includes determining the sound response of an acoustic environment,  determining the reciprocal of the sound response of that environment, and matching the absorption characteristics of the sound absorber to the reciprocal of the sound response.       Each  sound  absorber  has  a  linear  absorption spectrum above the center frequency so that clusters of the sound absorbers exhibit a similar spectrum.

Patent CA-2035996-C (CA)
Inventor: SAKAI KUNIHIRO
IPC: G11B9/00
Filed: 1991-02-02
Granted: 1998-01-06
Abstract: An apparatus capable of detecting a displacement of a probe from a track of a recording medium caused by track fluctuations, vibrations at recording/reproducing period.       For example, a probe 1 is maintained to vibrate at frequency f in the direction perpendicular to a data train 4 at an amplitude smaller than the width of the data train 4.  In this case, the amplitude of a reproduced signal of the data train changes with the displacement between the probe 1 and the data train.  The envelope signal i of the reproduced signal is phase detected using as a reference signal the vibration waveform (standard signal) at frequency f o of the probe 1, to obtain a signal proportional to the displacement from the data train.  Using this signal, it becomes possible to feedback control the probe 1 so as to make it trace the data train.

Title: Centrifugal blasting apparatus
Inventor: URAKAMI FUKASHI
IPC: B24C7/00
Filed: 1992-05-21
Granted: 1998-08-25
Abstract: Disclosed is an improved centrifugal blasting apparatus for for blast cleaning or shot peening treatment of a selected surface of an object to be treated by throwing pulverized abrasive material onto the surface.  Its wheel casing has an elongated slot to permit pulverized abrasive material to pass therethrough and scatter through the air with centrifugal force, which is given by the blades of the rotary blade wheel.  The inlet suction conduit extends from the blasting cabinet to the wheel casing, and the outlet suction conduit extends from the wheel casing to an associated vacuum pump.   The abrasive material storage or collector is provided in the inlet suction conduit, thus making up an abrasive material circulating loop.  The apparatus uses no force of gravity to supply pulverized abrasive material to its rotary blade wheel, and therefore, the positioning of the rotary blade wheel is not limited with regard to availableness of the force of gravity.  It requires neither air-tight ejector nor screw conveyers or bucket elevators, and accordingly its weight and size can be reduced substantially.

Title: Encoder, data detecting semiconductor integrated circuit applicable to the same and dynamic sense amplifier
Inventor: YONEDA MASATO
IPC: G11C15/04
Filed: 1993-01-08
Granted: 1999-03-02
Abstract: A encoder has a prefetch circuit or a flag data sense circuit built into the priority encoder provided for a CAM block.  While a hit signal in the first priority subblock is being encoded, a hit signal in the second priority subblock can be stored in the prefetch circuit.  Therefore, the encoding operation is performed without subblock-to-subblock switch time and this makes the encoder best suitable for a large capacity CAM which is required to operate at high speed.  Moreover, a semiconductor integrated circuit of the present invention detects the differential current between the current flowing through one signal line and the reference current flowing through the other signal line.  Moreover, it can operate as the number detection circuit to detect the number of hit signal in the subblock, and it can operate as the timing control circuit to previously notify the encode termination of the hit signal in the subblock of the encoder described above.  Therefore, this semiconductor integrated circuit can allow the encoder to encode very efficiently at high speed.  Moreover, a dynamic sense amplifier is able to operate with a great operating margin.
