Title: Platen drive mechanism
Inventor: TOYAMA TETSUYA
IPC: B41J13/076
Filed: 1989-06-01
Abstract: PURPOSE:To make paper of an arbitrary width available as paper to be fed by a platen by a method wherein platen holder holding the platen freely rotatably and a driver for rollers arranged nearly in contact with the platen are mounted, and the peripheral surfaces of the platen and the rollers are alternately magnetized to N poles and S poles respectively. CONSTITUTION:A cylindrical platen 21 made of a magnetic material, such as iron, is rotatably held by a platen holder 22. Three rollers 23 are arranged nearly in contact with a peripheral surface 21a of the platen 21 through three openings 23a. The peripheral surface 21a of the platen 21 and peripheral surfaces 23b of the rollers 23 are alternately magnetized to N poles and S poles respectively. When a motor 23 is driven, the force is transmitted to the rollers 23. When the rollers 23 rotate, e.g., in a direction of an arrow P, the attracting force of the N poles on the surface of the rollers 23 to the S poles on the surface of the platen 21 rotates the platen 21 in a direction of an arrow Q. The absence of a frame for supporting the platen 21 and a roller driver in the longitudinal direction of the platen 21 eliminates the need for restricting the width of the paper to be fed by the platen 21.

Title: Magnetic recording and reproducing device
Inventor: OOYAMA TSUTOMU
IPC: G11B23/28
Filed: 1984-07-06
Abstract: PURPOSE:To prevent easy duplication of a magnetic tape with a commercially available recording and reproducing device such as tape recorder by obliquely arranging the gap direction of a head which records and reproduces signals on and from a magnetic recording medium in the running direction of the recording medium. CONSTITUTION:When a tape, on which recording is made by using a recording and reproducing head 5 whose gap is inclined by an angle theta, is reproduced with an ordinary reproducing device, the frequency component at the high band of signals is damped and the data recorded on the magnetic tape cannot be fetched properly, since the direction of the head gap does not coincide. Moreover, when the tape is duplicated with an ordinary sound recording and reproducing device, the data recorded on the tape cannot be reproduced properly, since the data are recorded with the high band of the original signals being largely dampled. When a magnetic tape thus duplicated is reproduced by means of the device shown in the figure, the high band is further damped and the data cannot by reproduced properly, since the head gap direction is further deviated. A magnetic tape is used to explain this preventive measure, but the measure can also be applied to a magnetic disk.

Abstract: PURPOSE:To omit a special image pick-up pedestal by fitting a black-and-white TV camera to the titled device and picking-up a color original image by using a film deck in a photographing image exposing system. CONSTITUTION:In the case of picking-up images by the black-and-white TV camera 28, three primary color filters 15-17 arranged between a light source part 11 and the film deck 13 are successively inserted into an optical path, the image of a color original picture 14 set up on the deck 13 is picked-up by the camera 28 and red, green and blue image signals are successively outputted. These signals are sent to a video image exposing system, and after executing image processing such as color correction, gradation correction and synthesis, the processed signals are inputted to a black-and-while CRT 27. The CRT 27 prints out a color image on color paper 4 by three-color face successive exposure. Consequently, a special image pick-up pedestal can be omitted and a color original image can be picked-up by the black-and-white TV camera.

Filed: 1993-05-19
Abstract: PURPOSE:To provide single-crystal silicon carbide of good crystallinity when the single-crystal silicon carbide is generated on the surface of a seed crystal by sublimating the material for a silicon carbide, by assigning a metal silicon near the seed crystal. CONSTITUTION:A graphite pot 1 is filled with the material for a silicon carbide 4, and a graphite lid 2 is attached with a seed crystal 3, and further, a metal silicon 5 is assigned near the seed crystal 3, not in the material for a silicon carbide 4. In short, the metal silicon 5 is so assigned that the distance between the seed crystal 3 and metal silicon 5 is shorter than that between the seed crystal 3 and the material for a silicon carbide 4. Here, in such inactive atmosphere as argon, the temperature of seed crystal 3 is set lower than the material for a silicon carbide 4, and the seed crystal 3 and the material for a silicon carbide 4 are heated, so that the material for a silicon carbide 4 is sublimated for a single-crystal silicon carbide to be generated on the surface of seed crystal 3. Thus, a single-crystal silicon carbide monocrystal of good crystallinity is obtained.

Title: Printer
Inventor: INOTA YASUYUKI
IPC: G06F3/12
Filed: 1993-06-14
Abstract: PURPOSE:To make it possible to reset a printer by allowing a host to optionally turn its DTR signal or RTS signal (a DSR signal or a CTS signal for a printer) from a space state to a mark state. CONSTITUTION:When a DSR or CTS signal, from an RS-232C interface connector 3 is a space state and a power supply circuit part 2 is started, a reset circuit part 5 outputs a signal after the lapse of a prescribed time, a control circuit part 4 is reset and a program memory 13 is turned to a printable state. When a DTR or RTS signal from a connected host is a mark state, a signal from a driver/receiver 9 in a NAND 15 is 'L', so that the reset circuit part 5 does not output an 'H' signal even when the circuit part 2 is raised and the circuit part 4 is held at the reset state. When the software of the host turns the DTR or RTS signal of the host to the space state, the reset circuit part 5 outputs an 'H' signal.

Electrodes 28 are formed on the top and bottom surfaces and thereafter the layers are removed by selective etching to a circular shape up to and down to the GaAs layers on the top and bottom surfaces. The high quenching ratio is thus obtd. with the low voltage and intensity modulation of several tens GHz is made possible in principle.

Abstract: PURPOSE:To allow the peeling of a pellicle from a mask while decreasing the residues of a tacky adhesive material on the mask by immersing the mask and the pellicle into a solvent mixture having a specific volumetric ratio of water and alcohol soluble or partially soluble in water. CONSTITUTION:An optical thin-film body 1 is fixed by an adhesive layer 3 onto a supporting frame 2. This frame 2 has the tacky adhesive body 4 on the other end face as well and a protective film 5 is disposed thereon. The protective film 5 is peeled and is used by being mounted on the mask via the tacky adhesive body 4. There is a need for exchanging the pellicle with a fresh pellicle if the optical thin film body 1 is damaged or ruptured at the time of mounting or during the operation after the mounting or when the adhesion of foreign matter on the mask surface is found. The pellicle is, therefore, immersed together with the mask into the solvent mixture consisting of the alcohol having 2 to 5 carbon atoms soluble or partially soluble in water and the water and having 1/5 to 5/1 volumetric ratio. The pellicle is peeled by holding the supporting frame 2 after the proper time.
