Abstract: Disclosed is a paper feeder for sequentially feeding laminated cutform paper to a record/write portion or the like. Proper sagging of the cutform paper is produced on this side of a paper feeding roller during rotations of the paper feeding roller in an anti-feeding direction, thus adjusting the direction thereof. Subsequently, with rotations of the paper feeding roller in a paper feeding direction, a feed roller is temporarily rotated. The paper feeding roller is caused to exactly pull in the cutform paper without exerting abrupt fluctuations in load on the paper feeding roller and the cutform paper.

Abstract: A paper feeding apparatus for feeding fanfold paper to a printer is provided. A cylindrical platen is rotatably mounted in the printer. A paper feeding tractor is provided upstream from the platen in a paper feeding direction. A power mechanism drives the platen and the paper feeding tractor. A pair of rollers is located above the platen downstream from the platen in the paper feeding direction. One of the rollers is coupled to the power mechanism causing it to rotate with a circumferential speed which is greater than or equal to the circumferential speed of the platen. A pressing member presses the fanfold paper which is fed out from the platen towards the rollers.

Abstract: A type printer has at least two colors of ink applied alternately in a column direction and is shifted in the column direction for each rotation of the type drum. The type drum is automatically halted once the drum has completed two revolutions. A selection and stop release mechanism control rotation of the type drum, perform type selection and release an automatic stop state of the type drum at the beginning of each print line. A trigger mechanism is synchronized with a pulse generated by a detection mechanism and corresponds to the type position on the type drum. A damper mechanism substantially avoids vibration or rotational fluctuations in the type drum.

Abstract: A dot pattern data generating device including a character generator constructed to be readable by character code data for storing data representing a character pattern in the form of a matrix according to existence or non-existence of dots in the matrix. The device includes a region readout circuit for reading a local pattern of the matrix with one dot location from the matrix read from the character generator being centered in the matrix portion. An arithmetic circuit is also included for computing horizontal and vertical values from the local pattern. A pattern generating circuit generates a plurality of dots with respect to one dot of the original pattern on the basis of the horizontal and vertical values to generate an enlarged pattern. The enlarged character pattern is generated at a high speed without enlarging stepped portions of the oblique lines simulating smooth portions by generating enlargement dots corresponding thereto.

Abstract: A holster formed of a fabric material suitable for weapon with a laser light having internal retention. The holster is formed from a piece of synthetic material which is folded on itself and secured to a barrel stop at the bottom to form a cavity for receiving the weapon. An elastic strap along the back opposite the fold line secures the weapon in the holster and urges the weapon towards retention elements secured to the inside of the fabric at the ejection port and trigger of the weapon.

Abstract: A liquid crystal display device wherein scanning voltages are applied to a plurality of scanning electrodes and signal waveforms are applied to a plurality of signal electrodes. The polarity of the voltages applied to the signal and scanning electrodes is inverted during predetermined periods. As the effective voltage of the display element is changed, correcting voltages are applied to the signal electrodes in order to reduce the contrast problem associated with changes in the effective voltage of adjacent display elements.

The base and sides of the reusable bag are formed of a semi-rigid form maintaining material which maintains its form while allowing each side and base to collapse upon itself.

Abstract: A portable audio apparatus allows a user to sing along with the recorded song, the user's voice and recorded song being outputted through a speaker. The apparatus permits the recorded lyrics or recorded tune of the song to be substantially eliminated prior to being reproduced by the speaker. The apparatus can operate in a fast forward or reverse mode and will stop between adjacent songs. A power savings circuit interrupts the supply of power to a motor to stop the latter from continuing to operate on a fast forward or reverse mode.

C. or above which refines the crystal grains and make them magnetically anisotropic. A process for producing a rare earth-iron permanent magnet by subjecting the ingot of said alloy to hot working at 500.degree. C. or above. The permanent magnet is equal or superior in magnetic performance to conventional permanent magnets produced by sintering method. The process is simple and able to provides permanent magnets of low price and high performance. In addition, an isotropic rare earth-iron permanent magnet is obtained if said ingot undergoes heat treatment at 250.degree. C. or above.

The apparatus includes a longitudinal heat-conducting element of a length generally corresponding to the length of the page edges to be bound. The apparatus further includes an actuator or starting signal to activate an electrical switch when the edges to be bound are contacted with the heating element, indicating that the heating process has started and continues to heat depending on the thickness of the leaves to be bound. The electrical switch is then disconnected, thereby generating a signal indicating the completion of the heating and binding process.
