IPC: B65H3/08
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To feed certainly recording paper (sheets) of any size without bringing about cost increase or an increase in the number of part items. SOLUTION: A plurality of sucking means 2A, 2B, 2C to attract a sheet P by the suction force given to the inside of a recess are held at moving means 3 and 3A and abutted on the sheet P by moving the means 3 and 3A when the sheet is to be attracted. The sheet sucking means 2C abutting on the sheet selectively in accordance with the sheet size is given a suction force from a suction force generating means 11 by a suction force giving means only at the time of abutting, and no suction force should be given at the time out of abutting. This precludes air from flowing into the suction force generating means 11 from the sheet sucking means 2C at the time of unabutting, and an attracting force required to make suction attachment is given to the other sheet sucking means 2A and 2B abutting on the sheet.

Title: Forming method of bump electrode
Inventor: KAWANOBE TOORU
IPC: H01L21/60
Filed: 1979-05-25
Abstract: PURPOSE:To obtain a bump electrode with reduced size and high density by a method wherein solder plating process for forming a solder electrode on a semiconductor substrate is divided into two steps and the applied solder layer is swollen to a shape of a semisphere under the action of surface tension by melting it after each plating. CONSTITUTION:An SiO2 film 17 is coated on the surface of an Si substrate 1, a passivation film 16 is provided on its periphery and then a metal film 8 is coated thereon overall. On this metal film 8, polyimide resin 11 is covered except for the region where a solder bump electrode is to be provided, and the first solder layer 12 is formed on the exposed portion of the film 8 by using the film 8 as a plating electrode. Then, the first solder layer 12 is swollen to a shape of a semisphere by wet-backing so as to form the first solder bump electrode 13. To compensate the less height of this electrode 13, plating process is repeated again to form the second solder layer 14 on the electrode 13, and thereafter the second solder bump electrode 15 with increased height is obtained under the action of surface tension by melting the electrode 13 and the layer 14. In such a manner, the solder electrode increases its height under action of the surface tension by melting it after coating the solder as a thin layer, thereby reducing the coating surface area and increasing the density thereof.

Title: Low-temperature-sintered ceramic dielectric and low-temperature sintered ceramic multilayer circuit board
Inventor: ADACHI SATOSHI
IPC: H05K1/09
Filed: 1995-03-23
Abstract: PURPOSE: To improve dielectric constant by mixing a specific amount of metallic powder into low-temperature-sintered ceramic. CONSTITUTION: A kind or a plurality of kinds of metallic materials such as Ag, Pd, Au, Pt, Cu and Ag-Pd alloy are mixed to low-temperature-sintered ceramic material sintered at approximately 1000 deg.C or lower and crushed. Solvent, binder and plasticizer are added to the mixed powder and kneaded to fabricate slurry having a low viscosity, so that a green sheet 14 with high dielectric constant is fabricated. At this time an amount of the metallic powder mixed to the low-temperature-sintered ceramic material is approximately 5 to 3wt.%. This increases the dielectric constant to approximately 20. Thus dielectric can be extremely easily sintered, while a manufacturing process is simplified and a cost is reduced.

IPC: H01M4/04
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To increase oxygen gas absorption while increasing the capacity of a battery so as to improve a heavy current charging-discharging characteristic by arranging a groove with a specific depth on an electrode surface of a cadmium negative electrode and forming a projecting part and a recessed part on the electrode surface. SOLUTION: In a sintered cadmium negative electrode for an alkaline storage battery, a porous nickel sintered base plate is impregnated with an active material principally consisting of cadmium hydroxide, and the depth of a groove in this negative electrode is set to be 0.1-20 μm. As the surface area of the electrode is increased, chemical oxygen gas absorbing reaction and electrical oxygen gas absorbing reaction are promoted without any deterioration of the battery capacity. In addition, if a PTFE layer is formed in a recessed part and a projecting part on the electrode surface, a binding property of PTFE is improved and a tri-layer interface is easily formed on the electrode surface, so that oxygen gas absorption can be improved further. Desirably, a PVP layer and/or PVA layer are/is formed on the projecting part on the electrode surface.  After electrical charging/discharging is repeated, coagulation of cadmium is prevented for prolonging a battery cycle life.

Title: Electronic wristwatch with solar batteries
Inventor: KOSHIBA SHIYOUHEI
IPC: G04C10/02
Filed: 1978-05-30
Abstract: PURPOSE:To lower the cost of an electronic wristwatch with solar batteries and improve its fashionability by constituting an overcharging preventing device with a multiplex liquid crystal display device and a switch thereby reducing the number  of solar batteries. CONSTITUTION:When, e.g, silver oxide cell is used as a secondary battery 2, the silver oxide cell is of about 1.6V in ordinary potential and is overcharged at above 1.8V causing battery deterioration. Thereupon, when a multiplex liquid crystal display device 8 whose threshold voltage is kept between 1.6V to 1.8V, there is no abnormality in display when the silver oxide cell is at a normal potential of about 1.6V and crosstalk occurs and the display decreases transmittance at the potentials between 1.6V to 1.8, at which the display becomes overall display and therefore the overcharging potential may be readily detected. Hence, the use of the overcharging preventing device constituted by the multiplex liquid crystal display device 8 and switch enables the electronic wristwatch of low cost and superior fashionability to be obtained.
