Patent JP-2000243358-A (JP)
Title: Nonaqueous electrolyte secondary battery
Inventor: SUGANO YOSHIMI
IPC: H01M10/05
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a sealing property and an internal short circuit caused by the volume change of an electrode active material in the high-temperature atmosphere by forming the battery inner side edge section of the bottom section of a gasket arranged between inner and outer cans into a circular arc shape or a chamfered shape. SOLUTION: The edge section 11a of a gasket 11 to be brought into contact with a separator 12 when the separator 12 is drifted from the regular position is formed into a circular arc shape, the force applied from above a battery at the time of sealing is converted into the lateral force for pushing back the separator 12 brought into the gasket 11, and the separator 12 is moved and sealed at the regular position. Since the edge section 11a is formed into the circular arc shape, the stress occurring in the battery can be made to hardly operate as the shearing stress to the separator 12.  The ratio of the circular arc radius(r) of the battery inside edge section 11a of the bottom section of the gasket 11 against the difference L between the inner and outer radii of the bottom section of the gasket 11 is set to 0.1-0.7, thus the shearing stress of the separator 12 is suppressed, and the strength of the gasket 11 is maintained.

Abstract: PURPOSE:To manufacture a semiconductor device having a P-N junction of small reverse current and to prevent a posing time from deteriorating when applied to a DRAM by forming an insulating film having a specific thickness on a semiconductor substrate, and implanting impurity ions through the insulating film to form a P-N junction. CONSTITUTION:An insulating film 10 having 1/2 or more of thickness of mean shooting stroke is formed on a semiconductor substrate 1, desired impurity ions are implanted through the film 10 thereby to form a P-N junction. For example, a LOCOS region 2 and an oxide film 10 having 250Angstrom  of thickness are formed on a P-type Si substrate 1, and with the region 2 as a mask As<+> ions are implanted. Then, an amorphous layer 3 is formed. Energy of this case is 80keV, dose of 5X10<15>cm<-2>. Then, when it is heat treated at 800 deg.C and recrystallized, only a defect type II5 remains. Thereafter, the film 10 is removed, an oxide film 6 and a BPSG film 7 are newly laminated. Eventually, when it is heat treated at 950 deg.C, the defect type II5 is eliminated, this element becomes non defective, and the surface of the BPSG film 7 becomes flat.

Title: Tension control device for metallic strip
Inventor: CHINO TOSHIHIKO
IPC: C21D11/00
Filed: 1987-12-18
Abstract: PURPOSE:To enable the accurate control of the tension on a metallic strip to target tension by dividing plural pieces of bridle rolls to 2 groups and disposing a dancer roll between the groups to absorb the tension fluctuation on an inlet side or outlet side. CONSTITUTION:Plural pieces of the bridle rolls are divided to the two groups; 20A, 20B and 22A, 22B and the dancer roll 24 is disposed between the groups. A motor 38 of a lifting and descending device 39 is controlled to specified torque and the tension Tm of the metallic strip 12 is maintained at a specific value by lifting and descending the dancer roll 24. The dancer roll 24 moves upward or downward to absorb the fluctuation when the inlet side tension T1 fluctuates momentarily. The tension Tm is thus maintained at the specified value. The position of the dancer roll 24 is returned to the home position by increasing or decreasing the pass speed of the front-stage bridle roll group 26A according to the change rate of the vertical positions of the dancer roll 24 of this time. The fluctuation in the inlet side tension T1 is, therefore, absorbed without inducing the hunting of the dancer roll 24. The fluctuation in the outlet side tension is controllable in the same manner.

Title: Facsimile equipment
Inventor: KIMURA SADAHISA
IPC: G03G15/22
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To provide the facsimile equipment which extends the supply time of an uninterruptible power supply equipment by automatically selecting the mode of the facsimile equipment to the mode requiring a small power consumption, in the case than the facsimile equipment is connected to the uninterruptible power supply equipment. SOLUTION: Upon the receipt of a signal being a battery output resulting from an abnormal commercial power supply (S10), a facsimile equipment confirms (S11) its own current operating state, the facsimile equipment selects the energy saving mode, when the facsimile equipment is set in a preheat standby state (S13) so as to reduce the power consumption. In the case of the usual standby state (S11; N), when it becomes time to set to the preheat state, the facsimile equipment does not select the preheat standby state but selects the energy-saving mode standby state requiring small power consumption.  In this case, on the occurrence of an abnormal signal, a message is displayed with is easy to see position for the entire equipment, such as an operation section in a way of abnormality processing, and the opportunity of the use of the facsimile equipment for not urgent facsimile transmission and copy is reduced so as to extend the reception available time (S12).
