Title: Reading method for crossed square-shaped code
Inventor: TAKAHASHI MAKOTO
IPC: G06K7/10
Filed: 1987-09-16
Abstract: PURPOSE:To accurately read a crossed square-shaped code by setting a reading start line in a first direction parallel to the crossed square-shaped code together with a reference line set in parallel with the reading start line and against allowing the inference line to respond to mesh set in the first direction and leading a scan line toward the crossed square-shaped code and the reference line from the reading start line. CONSTITUTION:When a reading start line 2 is scanned, the line 2 is surely extracted since this line has the longest picture element and the coordinates of both ends of the line 2 are read. The scan proceeds to a second direction and a scan line reaches a reference line 3. This line 3 is decided as long as the error is set at the value less than 1mm from a code 1 along the upper direction of the line 2 where the coordinates of its lower end are already obtained. The coordinates of said lower end is updated as a reference point for decision when a reference line 3b is extracted. When the line 3a is extracted, mesh information on the line 3a is set at 1. Hereafter the mesh information 0, 4, 0, 5... are decided based on the reference lines 3b and so on. By such as constitution, the position of a crossed square-shaped code is accurately obtained and at the same time the information on this code is accurately read.

Abstract: PURPOSE:To quicken a reading speed without changing a light storage time by summing picture element outputs of n-sets of solid-state image pickup elements adjacent to each other and outputting the sum when a picture is read with a resolution being 1/n of a highest resolution. CONSTITUTION:Coding picture data stored on a magneto-optical disk device 17 are read by a SCSI bus transfer control circuit 13 via a SCSI bus 14 and stored tentatively in a picture data buffer RAM 12 by a picture data transfer control circuit 15. Then coded picture data are read from the RAM 12 by the circuit 15, fed to a picture data expansion circuit 11, in which the data are subjected to decoding expansion processing. At reproduction output, since an input changeover circuit 9 is thrown to the position of the circuit 11, decoded original binary picture data are fed to a picture display device 16 via the circuit 9, on which the reproduced picture is displayed. Thus, read speed is quickened more without changing the light storage time.

Title: Separator roll for storage battery
Inventor: MUTOU JIYUNSUKE
IPC: H01M50/469
Filed: 1988-09-14
Abstract: PURPOSE:To make a battery assembly job efficient even after long term storage by rolling a separator with the thickness under a pressure of about 20kg/dm<2> retained. CONSTITUTION:A separator roll 3 for a storage battery is formed by rolling a belt-shaped separator 1 practically made of glass fibers alone. If the area of the side 1a in the direction of length when the pressure A of 20kg/dm<2> is applied to the separator 1 before it is rolled is S1 and the area of the side of the separator 1 after rolled is S2, the relation of S2 to S1 is 95-120%. Since the separator unrolled from the roll 3 is made somewhat hard, even if a pressure of 20kg/dm2 is applied to the direction of thickness, the thickness of the separator is almost equal to that of a new separator to which a pressure of 20kg/dm<2> is applied. The separator retains almost the same thickness as a new separator even after long term storage.

Title: Voting circuit for fault masking
Inventor: KOBAYASHI TOYOHIKO
IPC: H03K19/003
Filed: 1986-09-30
Abstract: PURPOSE:To automatically and exactly correct an output error of a voting circuit itself, by sending out a voting signal as data, comparing a feedback signal and the voting signal, and outputting the data which becomes a value obtained by adding a logical value '1' to a value of the feedback signal, only when both signals do not coincide with each other. CONSTITUTION:When a signal of a level '0' of faulty modules B, D and G is inputted to each of the corresponding input bits 2<1>, 2<3> and 2<6> of a processor 1, as a result of voting of modules A-H, '1' is outputted to a 2<0> bit of data. In this state, when it is supposed that the level '0' has been discriminated by mistake as a feedback signal 4a from the processor 1, a 2<8> bit of the address becomes the level '0'. subsequently, to 2<1>-2<7> bits of the data, a value which has added '1' to a value of 2<9>-2<15> bits of the address is outputted. Accordingly, a voting signal 30 is corrected to the level '1' as a result of correct voting, even if the level '0' is outputted by mistake.
