摘要:
A superior lithium secondary battery having high total discharge capacity, high effective discharge capacity, high total discharge efficiency, and high effective discharge rate can be obtained by using, as a carbon electrode for a lithium secondary battery, a carbon for a lithium secondary battery obtained by successively conducting a halogenation treatment, a dehalogenation treatment, and a pore adjustment treatment on a dry-distilled charcoal, or by successively conducting a crushing treatment, a molding treatment, and a carbonization treatment on a dry-distilled charcoal.
摘要:
A halogen treatment is conducted comprising: a halogenation step wherein a halogenation heat treatment for preparing a halogenated carbonized charcoal is conducted in which the carbonized charcoal is brought into contact with halogen; and a dehalogenation step wherein a dehalogenation treatment is conducted in which a part of or all halogen atoms in the halogenated carbonized charcoal are eliminated. A porous carbonaceous material is obtained at a high yield, and the amounts of nitrogen, oxygen, carbon dioxide, and methane adsorbed by this porous carbonaceous material are large. When this porous carbonaceous material is used as an electrical double layer capacitor carbon, the electrostatic capacity is increased compared to conventional carbonaceous materials. Consequently, a carbonaceous material is obtained which has micopores and/or sub-micropores which are suitable for the adsorption of small molecules such as nitrogen, and for storage of electrochemical energy.
摘要:
It is possible to increase the amount of nitrogen generated per unit of adsorbent, raise the nitrogen yield, and reduce the manufacturing cost for nitrogen by using, as an adsorbent for the separation of nitrogen, molecular sieving carbon obtained by successively conducting a halogenation treatment, a dehalogenation treatment, and a pore adjustment treatment on a carbonized charcoal. By using activated carbon obtained by successively conducting a halogenation treatment, a dehalogenation treatment, and an activation treatment on a carbonized charcoal, as an adsorbent for carbon dioxide and methane, it is possible to improve the amount adsorbed.
摘要:
A carbonaceous material for an electrical double layer capacitor is produced by performing a halogenation treatment step wherein a halogenated dry-distilled charcoal is obtained by bringing a dry-distilled charcoal into contact with a halogen gas; a molding treatment step of adding a binding agent to the halogenated dry-distilled charcoal to form a molded article; and a dehalogenation treatment step wherein a part or all of the halogen in the molded article is eliminated. The carbonaceous material for an electrical double layer capacitor obtained by this method is impregnated with sulfuric acid to form a carbon electrode for an electrical double layer capacitor. This electrode is used to form an electrical double layer capacitor.

摘要:
An information processing apparatus driven by an AC power supply or a rechargeable battery has a charge directing unit which initiates charging of the battery from the AC power supply, provided that the remaining amount of power of the battery is lower than a predetermined charge-start-criteria level and that the information processing apparatus is driven by the AC power supply. Also included is a drive history storage which stores a drive history including information indicating which of the AC power supply and the battery was driving the information processing apparatus in each time period in the past. A recharge-start-criteria-level-setting unit sets the charge-start-criteria level on the basis of the drive history.
摘要:
A semiconductor memory device characterized by the fact that the disturb test time of the semiconductor memory device can be shortened, and the power consumption can be cut.In the disturb test for the semiconductor memory device in this invention, multiple word lines are selected at the same time with a prescribed interval corresponding to the element isolation layout. As the word lines are selected corresponding to the element isolating layout, the interference caused by the element isolation state can be excluded. Since multiple word lines are selected at the same time, the time of operation can be shortened. Since the word lines are maintained in the selected state while the sense amplifiers are not reset, there is no increase in the power consumption although multiple word lines are selected at the same time.

摘要:
Data selector circuit including a plurality of data registers connected in parallel via corresponding output buffers to a plurality of output drivers, wherein a decoder and selector portion is interposed between the output buffers and the output drivers for selectively providing one of a plurality of serial data output sequences from the data registers to the output drivers rather than a parallel data output format from the plurality of data registers which would otherwise occur. The decoder and selector portion is controlled by a partial address buffer which is provided with serial sequence selection data. Upon decoding the serial sequence selection data of the partial address buffer, a plurality of MOS transistors included in the selector portion are rendered conductive in sequence in response to respective control signals applied to the gates thereof to connect the plurality of data registers via their output buffers to respective output drivers in a sequence determined by the decoded selection data of the partial address buffer for serial data output in the selected serial data output sequence.
