Abstract:
A nonaqueous electrolyte battery is disclosed which is capable of improving impact resistance while airtightness of a laminate film is being maintained. When a battery element is accommodated in a casing constituted by a laminate film and the case is welded to enclose the battery element, a resin layer is provided for at least one surface of a battery element. The resin layer may be a resin plate which has previously been molded or the resin layer may be formed by enclosing resin. The resin layer is provided for two sides of all of the sides of the battery element which have smallest areas. In a case of a wound-type battery element, the resin layer is provided for the two end surfaces of the wound battery element. The resin layer has a shock buffering function to protect the battery element from impact.
Abstract:
A nonaqueous electrolyte battery is disclosed which has an improved volume energy density and satisfactory impact resistance, a heat radiating characteristic and producibility. A battery element is accommodated in a casing constituted by a laminate film so as to be sealed by welding. Electrode-terminal leads electrically conducted to electrodes which constitute the battery element are sandwiched by welded portions so as to be exposed to the outside portion of the casing. A control circuit of the battery is mounted on a welded portion of the casing. Since the control circuit of the battery is mounted on the welded portion of the casing, the space in the battery in which the battery element is not present can effectively be used. Therefore, the volume efficiency can considerably be improved.

PROBLEM TO BE SOLVED: To carry out a mask defect inspection in a short period of time with high accuracy. SOLUTION: The apparatus is equipped with: an inspection area operation section 51 to operate the inspection area around a segment functioning to seam drawn images from the drawing data of a mask; a pixel setting section 52 to divide the inspection area operated by the inspection area operation section 51 into a plurality of pixels; a reflected image deciding section 53 to take in the reflected image on the mask surface in the inspection area and to decide whether possibility of failure is present or not in the segment; and a segment deciding section 54 to take in the translucent image of the mask in the inspection area when possibility of failure is decided to be present in the segment by the reflective image deciding section 53 and to compare the taken-in image with a preliminarily taken in reference image by each pixel unit to decide whether failure in the segment is present or not.

PROBLEM TO BE SOLVED: To dissolve generation of the encapsulation failure which was caused by a gap remaining between a lead electrode side face in encapsulation part in a drawing position of a lead electrode and sheathing material, and make a well sealing of a battery encapsuled by the sheathing material to yield high productivity. SOLUTION: In a process to seal ends of sheathing materials 3a, 3b and lead electrodes 1a, 1b with fused sealants 2a, 2b, or in a process to make sealants 2a, 2b fuse and adhere to the lead electrode 1a, 1b, abrasive sheets 4a, 4b of material to which fused sealants 2a, 2b do not fusibly adhere are interveningly inserted between sheathing materials 3a, 3b or sealants 2a, 2b, and heaters 6a, 6b. Accordingly, even if the fused sealants 2a, 2b, come outside or leak from the ends of sheathing materials 3a, 3b, sealants 2a, 2b do not fusibly adhere to a surface of a heater or do not lose their shape.

PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte battery, in which reduction in discharge capacity with a sudden temperature change is remarkably reduced and which has excellent productivity, by unifying any one of a positive electrode active material and a negative electrode active material with a binder agent formed of the mixture of polyimide, of which imidation is completed and which can be dissolved in an organic solvent, and a fluorinated polymer. SOLUTION: A positive electrode having a positive electrode active material formed of a chalcogen compound, in which lithium ion can be freely inserted and drawn, and a composite chalcogen compound, which includes lithium, and a negative electrode having a negative electrode active material formed of a material, in which lithium ion can be freely inserted and drawn, such as carbon are provided so as to obtain a non-aqueous electrolyte battery. In this battery, an active material of any one of the positive electrode and the negative electrode is unified by the binder agent. As this binder agent, a mixture of polyimide, of which imidation is completed and which can be dissolved in an organic solvent and which is expressed with the formula, and a fluorinated polymer such as polyvinylidene fluoride is used. In the formula, Ar1 , Ar2 are aryls and (n) is an integer of 1 or more.

Abstract:
PURPOSE:To attenuate a digital input signal without deteriorating resolution or a dynamic range by pulse-width-modulating the signal by using the high-speed clock of the N-fold frequency of a reference clock at the time that the digital input signal is attenuated by 1/N unit and is taken out through a pulse width modulation circuit. CONSTITUTION:The data value DQ of the digital signal supplied to an input terminal 12 is increased by M-times by a multiplier 17, and is turned into a count number CN, which is supplied to the count number input terminal of the pulse width modulation circuit 11 constituted mainly of a counter. The reference clock pulse PCK of the frequency f0 is supplied to the input terminal 13, and by being sent to a frequency multiplier 18, it is multiplied by times of the reciprocal of 1/N of the unit of attenuation, that is, N-times, and is supplied to the modulation clock input terminal of the pulse width modulation circuit 11. A count start pulse St is supplied to the count start pulse input terminal 14 of the pulse width modulation circuit 11. Thus, the signal can be attenuated without deteriorating the resolution and without deterioating the dynamic range.
