Title: Printing control device for serial printer
Inventor: HIBINO MASAAKI
IPC: B41J19/18
Filed: 1990-10-12
Abstract: PURPOSE:To improve serviceability by a method wherein a printer, when shifted to compulsory reciprocating printing mode by operation of a printing mode-switching means, executes preferentially reciprocating printing regardless of commands for printing modes emitted from an upper device of the printer. CONSTITUTION:In the case where a command is sent coat from a host computer 12 for one-way printing for printing of such data as rulings, chinese characters or figures, a judgement is made that the given is one-way printing mode, and operation for one-way printing automatically continues until a next command for reciprocating printing comes in. When a switch 47 for giving of a command for compulsory reciprocating printing is turned on while the printer is still in the above-mentioned operation mode, an LED 48 lights up, and thereby the printer is put in the compulsory printing mode. When the printer is put in such mode, the compulsory reciprocating printing continues, disregarding the command for one-way printing even though said command is given by the host computer 12. When the switch 47 for giving of the command for the compulsory reciprocating printing is pushed down again while the printer is in the above-mentioned mode, the LED 48 is put out and the operation in the reciprocating printing mode under the normal command for the reciprocating printing from the host computer is restored.

Title: Production of magnetic recording medium
Inventor: SUGITA RYUJI
IPC: G11B5/85
Filed: 1985-12-06
Abstract: PURPOSE:To obtain a thin metallic film type magnetic recording medium which hardly curls by continuously forming a thin magnetic metallic film directly or via an underlying layer on a high-polymer substrate which curls during traveling. CONSTITUTION:The medium which hardly curls is obd. by using a polyimide film which curls outward on the side to be provided with a magnetic surface, heating the peripheral face of a cylindrical can to 240 deg.C and depositing a vertically magnetically anisotropic Co-Cr film 9 having 300-1,000Oe coercive force HCL in the perpendicular direction by evaporation on said film. The magnetic characteristics are improved when an underlying layer consisting of Ti, Ge, etc., is deposited by evaporation on the high-polymer film to about 100-500Angstrom  thickness and the film thickness with said extent hardly affects curling. A reversely curled film is used if the non-curling high-polymer film curls reverse when deposited by evaporation with the magnetic layer. The use of a polyamide or polyethylene terephthalate film or thin film consisting of materials besides Co-Cr for the substrate is equally effective.

Abstract: PURPOSE:To demultiplex optical signals with a uniform level to plural waveguides, by connecting optical switches arrayed in a matrix-like condition with each other by means of waveguides and adjusting the ratio of the optical signal level of both waveguides by adjusting DC voltages applied across the electrodes of the optical switches. CONSTITUTION:Optical switches 30-38 are arrayed in a matrix-like condition and each switch is connected with each other by means of waveguides. Under a condition where no branching connection is performed, each optical switch is controlled to a state where incident lights are not branched nor straightly advanced. Then a DC voltage is adjusted so that the ratio of the optical levels of both waveguides 11 and 14 can be set to a value of '3' or more, by making optical signals incident from a waveguide 10, changing the DC voltage across the electrodes provided in the optical switch 30, and branching the incident lights to the waveguides 11 and 14. Thereafter, the incident lights are branched to waveguides 12 and 15 by controlling the switch 31 in the same manner. Similar operations are successively repeated and the optical levels of the waveguides 14, 15 and 16 are made the same. As a result, the optical signals can be branched to waveguides 25, 26 and 27 with a uniform level.

Filed: 1990-10-15
Abstract: PURPOSE:To allow the high speed rotation and extension in length of a bobbin holder by disposing an open-sided bobbin holder for holding a number of bobbins and a touch roller rollingly making contact with the bobbin holder vertically upward to a base. CONSTITUTION:As bobbin holders 5, 6 are vertically upward, the weight of a full package P held thereby vertically works downward and does not work as a bending stress, and only the contact pressure works as the bending stress. Namely, the full package P held by the bobbin holders 5, 6 has a considerable weight, but its weight works vertically downward. Thus, it is only the contact pressure of a contact pressing cylinder 23 that acts on the horizontal direction of the bobbin holders 5, 6, and this force is not so much large. Thus, the bobbin holders 5, 6 can be rotated at high speed and extended in length.
