Title: Mask purifier
Inventor: FURUKAWA TAKAO
IPC: G03F1/00
Filed: 1979-04-09
Abstract: PURPOSE:To perform perfect purification and enhance the quality of a photomask by removing dust attached to a dry plate or a blank plate for forming a pattern at a state where the plate is isolated from the outside. CONSTITUTION:The space formed with dry plate holders 2 and the inner wall of lid-shape structure 6 of the mask purifier is evacuated through exhaust ports 11 made in the wall. While slowly rotating nozzle group section 8 at this state in a fixed direction, nitrogen gas mixed with ozone by ionizer 9 is sprayed from nozzles 10 at a right angle to dry plate 1 under predetermined pressure to blow away dust on plate 1, and the sut-containing gas is exhausted from ports 11 of the purifier. Section 8 is then evacuated to a vacuum through rotary shaft 7 to allow dust adhered to plate 1 to float by suction through nozzles 10. By alternately repeating the nitrogen spraying and the evacuation several times for about 10 sec plate 1 is purified perfectly.

Title: Magnetic recording medium
Inventor: AOYAMA SHIGEO
IPC: C09D7/12
Filed: 1986-02-28
Abstract: PURPOSE:To obtain a magnetic recording medium having an excellent electromagnetic conversion characteristic and excellent durability of a magnetic layer by using specific silane coupling agents in combination of two kinds into the magnetic layer. CONSTITUTION:The silane coupling agent having a polyalkylene oxide group in the molecule and the silane coupling agent having an amino group in the molecule are incorporated into the magnetic layer. The silanol group formed by the hydrolysis of the former silane coupling agent makes coupling reaction with the hydroxyl group on the surface of magnetic powder and adsorbs the polyalkylene oxide group toward the outside of the magnetic powder particles and therefore the dispersibility of the magnetic powder is highly improved by the stereoscopic protection effect of the adsorption layer. The latter silane coupling agent makes coupling reaction with the hydroxyl group on the surface of the magnetic powder and adsorbs the amino group toward the outside of the magnetic powder particles. The amino group reacts with the functional group contained in the binder resin or a polyisocyanate compd. as a crosslinking agent and since the secure chemical bond is formed among the same, the durability of the magnetic layer is improved.

Filed: 1984-03-07
Abstract: PURPOSE:To relieve an intra-office call in busy even when a master station side is faulty, by setting the intra-office call connection of a concentrating station by both a master station switchboard and the line concentrating station. CONSTITUTION:When calling information from a subscriber is transmitted to a master station switchboard H through a concentrating station R and a circuit 3, a call connection of an intra-office subscriber is executed by a face that the master station switchboard H switches a changeover switch SW under a control of a CPU47 and a channel control device SPC.

Filed: 1994-03-15
Abstract: PURPOSE:To provide a high-quality image by correcting a gradation for which the relation between the gradation of a recording pattern defining a prescribed area as one picture element and optical density is discontinuously changed. CONSTITUTION:Concerning a digital ink jet recorder, since a dot contour is made digital in the case of dedicated paper, the discontinuity of gradations is clearly actualized. Therefore, when the pattern of respective dots is regularly repeated at a certain density gradation in the case of executing digital recording while using a simple density pattern, the number of dots in the pattern of the gradation is not changed but dot positions are irregularly arranged and corrected. Otherwise, the pattern provided with the almost middle number of dots as many as the number of dots in the pattern of a gradation lower than this gradation value just for one gradation is replaced with the non-corrected gradation value and corrected. Thus, the image of the gradation provided with linear optical density can be provided.
