Title: Optical splitter
Inventor: TOKOEDA HIROYUKI
IPC: G02B6/28
Filed: 1995-04-06
Abstract: PURPOSE: To save space by integrally executing a non-reflection treatment of the unused terminals of an optical splitter composed of 2x2 optical fiber couplers. CONSTITUTION: Respective optical fibers 40 are connected to the non-used terminals 112, 211,...331, 342 of the respective optical fiber couplers 11, 21,...33, 34. Their front ends are lined up on a substrate 68 having V-grooves 64, etc., and are fixed by adhesive to form an optical fiber group 42. A slit 72 (inclining at >=8 deg. with a plane 50 perpendicular to the optical fibers) which crosses all the optical fibers of the group 42 and bites into the substrate 68 is formed and total reflection films 60 are inserted therein and are fixed by adhesives.

Title: Character recognizing device
Inventor: TATE YOSHIHIRO
IPC: G06K9/46
Filed: 1992-04-24
Abstract: PURPOSE:To provide a character recognizing device which can recognize the characters at a high speed and with a high recognizing rate despite the fine projecting/recessing part emerging at the contour of a character stroke. CONSTITUTION:A section where the black picture elements are continuous every (ni+1) times is secured in a character pattern 403 included in a binary image data area 401 with the scanning carried out in the direction of the Z-th scanning line Si (Z). If this desired section is not secured, the extraction of an observing point is complete. Meanwhile the middle point of the relevant section if secured is calculated. If the middle point is identical with the next observing point in the directional scanning, the extraction of the observing point is complete and the observing point is set at a point P41. Then the pattern 403 is scanned in the direction Si+4 (Z) in order to secure a section where the black picture elements are continuous every (ni+4+1) times and also the middle point of this section. If this middle point is identical with the observing point obtained just before the directional scanning, the extraction of the observing point is complete and the observing point is set at a point P43. If a variable (ni) showing the number of observing points extracted by the scanning in the direction Si (Z) reaches the prescribed value, the extraction of the observing point is complete. If not, the processing proceeds to the next step.

Title: Emergency information notification system
Inventor: OSAWA KATSUAKI
IPC: H04M11/00
Filed: 1993-05-07
Abstract: PURPOSE:To obtain a system notifying emergency information to an information adressee by a simple operation promptly and surely. CONSTITUTION:When a master station M performs a transmission information operation to a slave station S and detects the response of the slave station S, the master station transmits a message with emergency information to the slave station S, and when the salve station S listens to the message and performs a mode switching operation, the slave station transmits a mode switching signal and transforms its own station to a data mode. When the master station M receives the mode switching signal, transforms its own station to a data mode and transmits emergency information, and the slave station S receives the emergency information and performs a reception confirmation operation, reception confirmation data is transmitted to the master station M and the reception confirmation of the emergency information by the slave station S is taken at the master station M. When the slave station S is busy or performs no response and when the reception confirmation data can not be received at the master station M, the master station M repeats the transmission information to the slave station S. Thus, the transmission information operation is easy and the prompt transmission information is enabled because the transmission information is performed for all the slave stations S by the transmission information operation of one time at the master station M and information is surely transmitted because the transmission information is repeated till the reception at the slave station S is confirmed.

Abstract: PROBLEM TO BE SOLVED: To reduce drive power of data signal lines by dividing a signal side drive circuit into the same number of circuit blocks as the number of divisions of a data, or dividing the drive circuit into circuit blocks as many as a half of the number of divisions of the data. SOLUTION: When the number of divisions of a data and the number of divisions of a signal side drive circuit are expressed as A, and horizontal resolution of a panel is expressed by M, since the number B of latches 03 in each circuit block is B=3.n.M/A, a maximum value Ck of cross capacitance C to be connected with a data signal line (k) as a load is expressed as Ck=B.C =3.n.M.C/A. Moreover, the total cross capacitance of all the data signal lines Cd becomes Cd=A.B.C.(k+1)/2=3.n.M.C.(3.n+1)/2. Here, the signal drive circuit is divided into the number of divisions A of the data, and the number of the data signal lines to be arranged for each circuit block is made to (3.n) lines. This method can reduce round waveform of the data signal lines to 1/A and reduce the drive power of the data signal lines to about 1/A compared with a conventional method.
