Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To obtain a tactile sensor which prevents a mechanical quality factor from being reduced excessively, which prevents an inessential vibration from being generated and which can detect the hardness of an object precisely, by a method wherein a pressure-receiving part which is composed of a plurality of elastic layers is installed on the surface of a piezoelectric vibrator so as to come into stable contact with the object. SOLUTION: A tactile sensor is composed of a piezoelectric vibrator plate 1 (a piezoelectric ceramic) and of a piezoelectric vibrator which comprises a plurality of elastic layers 4, 5 which are bonded to the plate. On the basis of a change in the resonance frequency and the resonance resistance of the vibrator at a time when the vibrator is bought into contact with an object, the viscoelasticity of the object is detected.  The vibrator is constituted in such a way that an energy-confinement-electrode counter electrode 2a of a specific material in a specific size and a wiring part 3a of a specific material in a specific size are applied to the surface side of the piezoelectric vibrator plate 1 of a specific material in a specific size, that an electrode part 2b and a wiring part 3b are applied to the rear side of the vibrator plate 1, that an elastic body layer 4 made of a low-loss epoxy resin is bonded onto the electrode part 2a, and that an elastic body layer 5 is bonded further onto it. As a result, it is possible to prevent a quality factor from being reduced excessively and to prevent an inessential vibration, and the hardness of the object can be detected precisely.

Title: Multi cast method and exchange switch
Inventor: NAKAMURA MASAAKI
IPC: H04L12/18
Filed: 1995-04-28
Abstract: PURPOSE: To attain a multi cast in a multistage network consisting of plural exchange switches that perform the packet exchanges by preparing a buffer for the multi cast and also applying a special control system in a multi cast mode. CONSTITUTION: A multi cast buffer is added to an exchange switch of a conventional system to newly store a packet of the largest length. Then the multi cast buffer is used in such a case where the packets cannot be outputted to one or more ports via a switch when a multi cast is carried out in a multistage network using the Wormhole routing as shown in a diagram. As a result, the packets are sent to the output enable ports and at the same time the packt data are stored in the multi cast buffer. Then the data are taken out of the multi cast buffer and transferred when the output unable ports are turned into the output enable states.
