摘要:
A thermal recording system is used as a recorder in a facsimile equipment or the like, and usually has a first operational mode in which picture data being read out at a pitch of M lines/mm is recorded at a pitch of M lines/mm and a second operational mode in which picture data being read out at a pitch of (M/n) lines/mm are repetitively recorded for every n lines at a pitch of M lines/mm. In particular, in the second operational mode of the system, activation time periods of a thermal head in the repetitive recording of every n lines are controlled to be sequentially shorter as the lines advance, whereby a recording time in the second operational mode can be reduced and the deterioration of the recorded picture quality can be prevented.

A portable miter saw for cross-cutting and mitering elongated workpiece has a mechanism interlocked with the turntable for shutting the saw blade clearance gap in the guide fence. The mechanism is provided with a pair of shutter plates slidable on the guide fence and an interlocking piece connected to the shutter plates and movable in operative association with the turntable so as to linearly displace the shutter plates upon rotation of the turntable to selectively change the cutting angle of the saw blade.

A lithium ion secondary battery includes a positive electrode, a negative electrode, and an electrolyte provided between the positive electrode and the negative electrode. The positive electrode includes a positive electrode current collector and a positive electrode active material layer over the positive electrode current collector. The positive electrode active material layer includes a plurality of lithium-containing composite oxides each of which is expressed by LiMPO4 (M is one or more of Fe (II), Mn (II), Co (II), and Ni (II)) that is a general formula. The lithium-containing composite oxide is a flat single crystal particle in which the length in the b-axis direction is shorter than each of the lengths in the a-axis direction and the c-axis direction. The lithium-containing composite oxide is provided over the positive electrode current collector so that the b-axis of the single crystal particle intersects with the surface of the positive electrode current collector.

A disc reproducing apparatus includes: program readout means for playing back a disc loaded therein to read a program recorded thereon; disc-content readout means for executing the read program to read a content recorded on the disc; network-content acquisition means for executing the read program to acquire a content stored in a device connected over a network; and display control means for executing the read program to control display of the content read from the disc, and the content acquired from the device connected over the network.

A paper transportation control method for an apparatus enables conveying paper with appropriate tension on the paper by appropriately controlling a paper delivery operation of a delivery roller. When paper is conveyed by a paper feed roller pair of a roll paper printer, and tension on the paper is detected to exceed an upper tension limit based on displacement of a damping mechanism (a first time), a paper delivery operation of a delivery roller pair starts at a second time after a start operation delay time corresponding to a feed rate passes after the first time. When the tension returns to or below the upper tension limit, the paper delivery operation stops at a third time after a stop operation delay time similarly corresponding to the feed rate passes.

At least one of an aqueous solution A containing lithium, an aqueous solution B containing iron, manganese, cobalt, or nickel, and an aqueous solution C containing a phosphoric acid includes graphene oxide. The aqueous solution A is dripped into the aqueous solution C, so that a mixed solution E including a precipitate D is prepared. The mixed solution E is dripped into the aqueous solution B, so that a mixed solution G including a precipitate F is prepared. The mixed solution G is subjected to heat treatment in a pressurized atmosphere, so that a mixed solution H is prepared, and the mixed solution H is then filtered. Thus, particles of a compound containing lithium and oxygen which have a small size are obtained.

To increase the conductivity and electric capacity of an electrode which includes active material particles and the like and is used in a battery, a graphene net including 1 to 100 graphene sheets is used instead of a conventionally used conduction auxiliary agent add binder. The graphene net which has a two-dimensional expansion and a three-dimensional structure is more likely to touch active material particles or another conduction auxiliary agent, thereby increasing the conductivity and the bonding strength between active material particles. This graphene net is obtained by mixing graphene oxide and active material particles and then heating the mixture in a vacuum or a reducing atmosphere.

Texts including required message are entered with a small number of keys such as those of a cellular telephone. In this case, a conversion table is unnecessary and the number of key operations is reduced. The number of input characters or input character strings composed by sequentially selecting one from a plurality of alphabets distributed to sequentially entered keys is relevant to the number of operation keys (N) raised to the number of distributed character (M) power (=NM) including meaningless characters or character strings and, with respect to these, character conversion is executed by referring to a dictionary means, through the operation of the conversion next candidate key. The dictionary means stores numeric strings and words of meaningful characters or character strings among the said characters and character strings.
摘要:
In a thermal printing apparatus, three consecutive image data items in the main scanning direction is sequentially extracted. When all the three image data items are at level 0 (indicating that no dot is printed) and at level 1 (indicating that a dot is printed), a printing density is determined to be 0 (indicating that no dot is printed) and 3 (indicating that a dot of the highest printing density is printed), respectively. When one of the three image data items is at level 1, the printing density is determined to be 1 (indicating that a dot of the lowest printing density is printed) when the printing density of the preceding printed pixel is any value other than 0. When one or two of the three image data items is or are at level 1, the printing density is determined to be 1 or 2 (indicating that a dot of an intermediate printing density is printed) according to the printing density of the preceding printed pixel. Thus, the printing apparatus is capable of printing image data without the degradation of the image quality, even when the image data whose resolution in the main scanning direction is higher than (e.g., three times as high as) that inherent to the apparatus is supplied.
