Title: Optical output device
Inventor: OGURA WATARU
IPC: F21Y101/02
Filed: 2003-02-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a compact high-output flashlight capable of being safely grasped.  <P>SOLUTION: The flashlight 1 includes a housing 10 made of resin, and a heat dissipation plate 30 extending rearward along the inner wall of the housing 10 from an LED 20 located near the front end of the flashlight. The housing 10 of resin prevents its surface from getting hot, and a sufficient heat controlling capability is acquired due to the dissipation plate 30 provided inside and extending rearward. Therefore, even when the LED 20 is driven at high output above the rated output, the surface of the housing 10 is prevented from reaching such a high temperature that users would feel it abnormal. A temperature rise of the LED itself is also suppressed because heat dissipation is facilitated by the plate 30. This allows the white LED 20 to be continuously driven at high output with stability, and allows the flashlight 1 to be high-output, highly durable and compact.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Index structure for similarity search of numerical series data, and similarity search method using it
Inventor: MORINAKA TAKESHI
IPC: G06F17/30
Filed: 2003-02-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide: algorithm for significantly improving a degree of accuracy in refining an approximate solution for the correct solution for an L-index and compensating an error of an approximate line segment for this; an index mechanism to be used for this; a similarity search method using it; and a medium for storing a program for implementing the method.  <P>SOLUTION: The errors regarding all the possible cases are measured in advance and this maximal value is held as metadata. Degree of compensation is prevented from being excessive by compensating the error using this metadata. This enables the error to be compensated so that an approximate distance, or the distance of an approximate segments with each other, can be close to the real distance in the L-index. A problem of inefficiency, due to an excessive degree of this compensation, is solved and the approximate distance can be compensated closer to the real distance.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

A syndrome decoder 33 estimates the transmission data based on the received data with the error correction information and the probability information. Further, an error correction process is repeatedly performed while the number of rows of the parity check matrix is increased under a predetermined restricting condition until the error of the received data can be completely corrected.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
