Title: Pulse generator
Inventor: YASUI MASAAKI
IPC: H03K23/86
Filed: 1984-12-21
Abstract: PURPOSE:To obtain a forecast gate pulse with high accuracy by providing a means correcting the period of an up-down counter in order to synchronize the period of the up-down counter with the period of an input pulse train. CONSTITUTION:A coincidence detector 5 compares a setting value of a limit value setting device 4 with an output of the up-down periodic counter 2 and outputs a coincidence signal when the both are coincident. An up-down switch 6 receiving it command down-count to the counter 2. Then a divider 7, for example, halves an output of the counter 2, subtracts (8) the value from the setting value of the setting device 4 to revise the setting value. Thus, the period of the counter 2 is synchronized with the period of the input pulse train. Thus, a forecast gate pulse with high accuracy is obtained from the comparator 3.

Title: Manufacture of zro2 solid electrolyte film with sc2o3 and al2o3 added by sol-gel method
Inventor: CHIBA REIICHI
IPC: H01M8/02
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To manufacture a solid electrolyte film at low processing cost by adopting a sol-gel liquid containing Sc2 O3 , Al2 O3 and ZrO2 as a thin film forming material. SOLUTION: A manufacturing method of a solid electrolyte film of ZrO2 with Sc2 O3 and Al2 O3 added by a sol-gel method uses a sol-gel liquid containing Sc2 O3 , Al2 O3 and ZrO2 as a thin film forming material. Preferably, the solid electrolyte film contains 1-x-y parts of ZrO2 , x parts of Sc2 O3 and y parts of Al2 O3 (0.070<x+y<0.160, 0.005<y<0.050) because the thin film is so formed as to stabilize the cubic system and has a highly ion conductive composition. In addition, this cubic system is constructed three-dimensionally and the amount of Al2 O3 additives is small, hence a thin film manufacturing method such as an EVD method encounters difficulties in manufacturing the film.

Title: Processor system
Inventor: SHIDARA TATSUYA
IPC: G06F12/16
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To improve the performance of a system by backing up data independently of a main processor. SOLUTION: A timer 17 built-in a data transfer controller 5 sends a transfer request 22 to a memory controller 18 in constant cycles after a main processor 1 performs initial setting. The controller 18 sends a data transfer request 20 which is sent from a memory cell part 7 to a data register 8 to a dual port RAM 2. The RAM 2 transfers data from the part 7 to the register 8. After that, when the controller 18 activates a DMA(direct memory access) controller 19, data is transferred from the RAM 2 to a disk device 4 via a disk controller 3. In this way, the data of the RAM 2 can be periodically backed up to the device 4 independently of the processor 1 accessing the RAM 2 via a random port 9.

Title: Automatic paper feeder
Inventor: FUKUI KAZUYUKI
IPC: B65H3/68
Filed: 1987-10-28
Abstract: PURPOSE:To press a first paper feed roller onto a paper topmost surface at almost constant pressing force with its own weight as well as to miniaturize an automatic paper feeder by unitizing three rollers; a first paper feed roller contacting the paper topmost surface under pressure, a second paper feed roller constituting a handling mechanism and a separate roller in one, and pivotally supporting this paper feeding unit free of vertical rocking motion. CONSTITUTION:Paper P is fed from one on a topmost layer on the basis of rotation of a first paper feed roller 15 being in pressure-contact with a paper topmost surface. Then, it gets into a nip part between a second paper feed roller 16 and a separate roller 25 as being guided by a guide member 20a, and the paper other than one sheet on the topmost layer is put back by reverse rotation of the separate roller 25, so that only the one sheet on the topmost layer is going to be fed to the downstream side. At this time, a paper feed unit 10 consisting of these rollers will go down with a fulcrum shaft 12 as the supporting point in proportion as residual quantity of the paper P decreases. The first paper feed roller 15 comes into contact with the paper topmost surface on a paper mount 1 with constant pressure-contact force according to the level. In consequence, such a mechanism as pushing the paper mount up becomes unnecessary, and thus a paper feeder is made compact in size as a whole.
