摘要:
A feeding device for feeding a recording medium having a predetermined printing area on one of its opposite surfaces. The printing area extends in a printing direction. The feeding device includes a pair of feed rollers which holds the medium therebetween in rolling contact with the opposite surfaces of the medium. At least one of the pair of feed rollers is driven so as to rotate about an axis perpendicular to the printing direction, to feed the medium in the printing direction. One of the feed rollers which contacts the above-indicated one surface of the medium has an outer circumferential surface which includes a small-diameter portion whose diameter is smaller than that of the other portions. The small-diameter portion is aligned with the printing area in a direction of width of the medium perpendicular to the printing direction, so that the small-diameter portion is prevented from contacting the printed image. The feed rollers may be replaced by a platen roller of a printer. The platen roller is rotated about an axis perpendicular to the printing direction, and cooperates with a print head of the printer to hold and feed the recording medium such that the platen roller and the print head contact the opposite surfaces of the medium. This arrangement also protects the printed image from an adverse influence by a feeding action of the feeding device.
摘要:
The present invention concerns a safety device for a radiator cap detachably mounted on a fluid supply opening for closing the radiator opening. The safety device comprises a lock means for preventing the opening of the radiator cap when the temperature of the coolant in the radiator is higher than a predetermined value. The lock means is provided between the radiator cap and an inner surface of the fluid supply opening. The lock means comprises a lock portion provided on an inner surface of the fluid supply opening and a lock member fixedly secured to the radiator cap. The lock member is formed of a shape memory alloy.
摘要:
A printing apparatus comprising a keyboard which inputs characters, symbols, etc., to the apparatus and a display which displays the input characters, symbols, etc. A CPU supplies to a printing head dot pattern information in accordance with the information on the input character, symbols, etc., stored in a main memory. It also inverts the dot pattern information upside down, as needed. The printing head may print onto a lettering tape.

The present invention is directed to a metal/hydrogen alkaline storage battery, which comprises a positive electrode of a metal oxide, a negative electrode of a hydrogen-storage alloy, and a separator impregnated with an alkaline electrolyte and placed between the positive and negative electrodes. The electrodes and separator are housed within a sealed type battery casing. The casing has a device for maintaining the pressure in the battery in a selected range of from an equilibrium pressure required for absorbing hydrogen by the negative electrode to about 20 kg/cm.sup.2.

摘要:
A tobacco smoke filter includes a corrugated tape-like wrapping which, together with an outer perforated or otherwise air-permeable paper, defines a set of longitudinal grooves. Each of the grooves includes a blocking member, so as to inhibit direct smoke flow through the grooves and promote a ventilation effect. The blocking members in each groove are longitudinally staggered from one groove to the next to simplify the production of the device.
摘要:
A filter plug having a dual structure comprising filter element A made from a crimped long filter tow in a form of a plug, filter element B, joined to said A, prepared by wrapping a core material consisting of a long fiber tow in a sheet-formed product having grooves which is formed from a material having an air permeability of 8 liters/minute or less and an air permeable wrapping paper and/or a wrapping paper with perforated openings on its periphery which is wrapping therein said filter elements A and B so that the outer grooves parts of the sheet-formed product pass through in the longer direction of the filter plug.
摘要:
Provided are novel ligands for transition metal complexes which exhibit high coordination power with respect to metals by being free of substituents at the positions ortho to phosphorus or arsenic and which have electron-withdrawing power comparable to the highest level known in conventional ligands. One ligand includes a compound represented by General Formula (1): R1R2R3A or General Formula (2): R1R2A-Y-AR3R4 and having a total of 15 to 110 carbon atoms. In the formulae, A is phosphorus or arsenic; R1, R2, R3 and R4 are each independently a substituted pyridyl group having optionally different electron-withdrawing groups bonded to the positions meta to the atom A as well as hydrogen atoms bonded to the positions ortho to the atom A; and Y is a divalent group derived from a C2-20, optionally substituted and optionally heteroatom-containing, aliphatic, alicyclic or aromatic compound or from ferrocene.

摘要:
This invention is directed to correcting a smear by a line-sequential reading scanner. To accomplish this, in a line-sequential reading type image reading apparatus (scanner), the first memory stores reference smear amount data of a smear occurred for each color component. The correction amount for the brightness value of each color component obtained by reading an original by an image sensor is calculated based on the reference smear amount data stored in the first memory and the brightness value level of a pixel on a preceding line. The brightness value is corrected based on the correction amount.
