Title: Revolution sensor
Inventor: HARADA YASUHIRO
IPC: G01D5/245
Filed: 1995-04-28
Abstract: PURPOSE: To enhance the detection sensitivity of an electromagnetic pickup-type revolution sensor using a windowed rotor. CONSTITUTION: A residual thickness part 93 as the end part of a window part 91 at a windowed rotor 9 is arranged away from a magnetic gap 14 in a core 13 for an electromagnetic pickup 5. As a result, when the window part 91 is overlapped with the magnetic gap 14, a magnetic flux which is passed through one pair of cores becomes small, and a reluctance is increased. Consequently, the amplitude of a magnetic-flux change due at the rotation of the windowed rotor 9 becomes large, and the detection sensitivity of a revolution sensor is enhanced. In addition, without expanding the dimensions of the revolutions, the effective overlap length of tooth-pillar parts at the windowed rotor 9 with tooth poles of the cores is made long.  As a result, when the tooth-pillar parts are overlapped with the tooth poles of the cores, the magnetic flux which is passed through the pair of cores becomes large. The amplitude of the magnetic- flux change thereby becomes large, and the detection sensitivity of the revolution sensor is enhanced.

Title: Optical information reader
Inventor: MATSUSHIMA TAKESHI
IPC: G06K7/00
Filed: 1993-06-01
Abstract: PURPOSE:To enable high-speed reading by shortening a time required for analyzing data. CONSTITUTION:Although a minimum time required for one time of decode is 3T similar to the conventional case, as for a time required for attaining the coincident of data (n) times, the time required for analyzing the data is shortened by the time of decode in comparison with the conventional decoding results since fetched bar width data are successively compared. Therefore, the minimum data analyzing time is T (n+2) and can be shortened by T (n-1) in comparison with conventional analyzing time of T (2n+1). When the decode is failed (m) times in the middle of processing, a time required for attaining the coincidence of decode data (n) times is finally turned to T (n+2) +Tm. The analyzing time prolonged by failing the decode once is T, and the time can be shortened by half in comparison with the conventional time of 2T.
