  • Patent number: 6153822
    Abstract: A musical apparatus which controls a variety of parameters of musical tones by detecting motion of an object in a space adjacent to the musical apparatus. More specifically, the musical apparatus may comprise a musical tone signal generator which generates a musical tone signal, at least one light source which radiates light beams into a space adjacent to the musical apparatus, at least one light detector which detects at least two light beams reflected from an object in the space and generates a detection value for each of said at least two light beams, a computing element which receives the detection values and generates a synthesized value; and a controller which controls parameters of musical tones based on the synthesized value. For example, the synthesized value may be the sum of the detection values, the difference between the detection values, the ratio between the detection values, or some other relationship between the detection values.

  • Patent number: 6111182
    Abstract: A system for editing and reproducing sounds according to pre-stored waveform data and recorded waveform data is disclosed. Pre-stored waveform data including timing information and musical tones are stored in memory. Musical tone waveform data including timing information from external sources such as electronic musical instruments, non-electronic musical instruments, and voices can also be stored in memory. The waveform data stored in memory can be edited before it is sequentially read out and a musical tone signal is reproduced.

  • Patent number: 6076242
    Abstract: A cut pile fabric with substantially vertically standing tufts made of a synthetic multifilament yarn which is an intermingled yarn comprised of (a) a crimped multifilament yarn and (b) a non-crimped highly heat-shrinkable multifilament yarn having a heat shrinkage larger than that of the crimped multifilament yarn (a), and having thick portions and thin portions, alternately occurring along the length of each constituting filament of the yarn (b), said thick portions having a heat shrinkage larger than that of said thin portions. When heat-treated, the cut pile fabric provides a high-and-low cut pile fabric having a unique appearance. Especially when tip portions of cut piles of the crimped multifilament yarn (a) are entangled with each other, a cut pile fabric having a rugged surface with lumps of snarled piles is obtained.

  • Patent number: 6022797
    Abstract: First through holes of a relatively small diameter and second through holes of a relatively great diameter are formed in proper shapes by separate processes, respectively, in a first layer insulating film. The second through holes are tapered toward a layer underlying the first layer insulating film. First, the first through holes are formed in the first layer insulating film, the first through holes are filled up with plug electrodes, and the second through holes are formed in the first layer insulating film. When filling up the first and the second through holes formed in the first layer insulating film with plug electrodes, a first conductive film deposited over the first layer insulating film is etched back to fill up the first through holes with the plug electrodes, and then etch back residues remaining on the side walls of the second through holes are removed.

  • Patent number: 5700704
    Abstract: A method is provided for manufacturing a semiconductor integrated circuit device which includes a capacitor element having a first electrode, a second electrode, and a dielectric film formed between said first electrode and said second electrode. In particular, the method includes the step of forming at least one of the first electrode and second electrode with a polycrystalline silicon film which is deposited over a semiconductor substrate by a CVD method and which is doped with an impurity during said deposition to decrease the resistance of the polycrystalline silicon film. The capacitor element formed by this method is particularly useful for memory cells of static random access memory devices.

  • Patent number: 5636275
    Abstract: A hinge mechanism for use in a portable telephone in which a foldable lid is rotatably supported by the hinge mechanism to rotate the foldable lid between an opened position and a closed position, includes a rotary shaft on which the lid is rotatably supported. A first spring, fitted to the shaft, generates a biasing force to rotate the lid on the shaft in a first direction from the closed position to the opened position. A second spring, fitted to the shaft, generates a biasing force to rotate the lid on the shaft in a second direction opposite to the first direction after the lid is further rotated from the opened position in the first direction. A first stopper restricts a rotation of the shaft in the first direction to cancel the biasing force of the first spring when the lid is further rotated on the shaft in the first direction from the opened position.
