Title: Method for forming coating layer to roll
Inventor: HANAZONO SHIGEYA
IPC: B29C65/02
Filed: 1990-06-21
Abstract: PURPOSE:To easily form a strong coating layer of uniform quality on the surface of a roll by a method wherein the roll on which a fluoroplastic cylindrical body is shrunk under heating in the atmosphere is received in a vacuum furnace and the vacuum degree in the furnace is set to a specific value to exclude the air interposed between the surface of the cylindrical body and that of the roll and, thereafter, heating is started to thermally weld the cylindrical body to the roll at temp. equal to or higher than the m.p. of the resin. CONSTITUTION:A heat-shrinkable fluoroplastic resin cylindrical body is externally fitted to a roll and the whole is heated in an atmospheric pressure furnace to thermally shrink the cylindrical body. Subsequently, the roll is arranged in a vacuum furnace and the vacuum degree in the furnace is set to 10<-3>-10<-2>Torr by a usual method and the roll is heated to weld the thermally shrunk cylindrical body to the roll. Thereafter, heating is stopped and air (room temp.) is sent in the furnace to return the vacuum degree in the furnace to atmospheric pressure and the roll is taken out. By this method, the resin cylindrical body can be perfectly welded to the surface of the roll under heating.

Title: Distillation temperature control method in dry cleaning
Inventor: KUROKI KIYONORI
IPC: D06F43/08
Filed: 1990-06-21
Abstract: PURPOSE:To prevent bumping phenomenon in distillation process and perform effective distillation without decomposition of a solvent by regulating a manual pressure reducing valve to obtain a necessary desired temperature, and controlling an automatic opening and closing valve on the basis of the detection value of a temperature detecting sensor to close at the time of detecting the desired temperature or higher, and close at the time of detecting a temperature lower than the desired temperature. CONSTITUTION:A temperature detection sensor 29 is provided in the heating jacket 24 of a distiller. Thus, the temperature detection sensor 29 is never contaminated by a soiled solvent, and can detect a precise vapor temperature. Further, as a desired vapor temperature is set by a manual pressure reducing valve 31, the vapor temperature sent to the distiller generally keeps a temperature set by the pressure reducing valve. However, when the temperature is raised to the set temperature or higher by any cause, the temperature detection sensor 29 detects it to close an opening and closing valve 26 by a control part 30. When the temperature is lower than the set temperature, the opening and closing valve 26 is similarly opened. Thus, smooth and effective distillation can be performed while keeping a temperature of 15O deg.C-147 deg.C, for example, to prevent bumping and decomposition the solvent.

Title: Printing medium discharge method in printer
Inventor: FUKUNAGA MASAMI
IPC: B41J13/00
Filed: 1988-06-29
Abstract: PURPOSE:To discharge the rear end of a printing medium to a position easy to take out by detecting the leading end and rear end of the printing medium to measure the length thereof and comparing the measured length of the printing medium with a preset standard length. CONSTITUTION:The feed of a printing medium P is started toward a feed passage R and, when the leading end FP of the printing medium P is detected by a sensor S, a stepping transfer clock 41 starts counting in a count circuit. The rear end TP of the printing medium P passes the sensor S and the length thereof Px is detected at the point of time when the sensor S becomes an OFF-state. In the count circuit part, the counting of the number of clocks by the stepping transfer clock 41 is finished and said number of clocks are measured a the length Px of the printing medium P by an operation part. The length Px of the printing medium is compared with a preset standard length (m) by the operation part. For example, when the length Px of the printing medium P is shorter than the standard length (m), the sensor S detects the rear end TP of the printing medium P to be turned ON and subsequently counts the number of clocks corresponding to the distance up to a predetermined position N2 and the printing medium is discharged until the leading end FR thereof reaches a position N2.

Title: Switching circuit
Inventor: SUZUKI TOSHIYASU
IPC: H03K17/08
Filed: 1994-06-10
Abstract: PURPOSE:To generate a large voltage against such a large current as a short circuit current, and to maintain a reverse bias action by providing with a means which does not output an ON-signal to a switch device, when a switching means is ON. CONSTITUTION:When a switch 6 is turned on, and a large power source short circuited current flows through a transistor 3 and the switch 6, a large voltage drop is generated in a current limiting means 4, and a large base reverse bias voltage is impressed to its emitter junction. Also, even if a load current flows between terminals 12, 13 during an ON-period of the switch 6, its current is smaller than the power source short circuited current, and only a small voltage drop is generated in the means 4, therefore, an energy loss by the means 4 is small. In such a way, as keeping a large reverse bias voltage maintaining, the energy loss can be decreased.

Abstract: PURPOSE:To obtain a small-sized, light developing roller at low cost and to reduce density irregularities, etc., caused by the fluctuations of a magnetic field and the thickness of a toner layer by holding a gap larger than the thickness of a developer layer between the developing roller and a latent image carrier, and obtaining the developing roller where an alternating electric field is formed on a developing region. CONSTITUTION:The latent image carrier 8 and developing roller 2 are arranged so as to have the gap larger than the thickness of magnetic toner 1. The developing roller is constituted that the developing roller itself has, at least, a magnetic field generating layer, and it has conductivity or an independent conductive layer. A device which is miniaturized, and reduced in weight and cost can be attained, with simple structure. On the other hand, the toner is held in a range where the magnetic field of the magnetic field generating layer magnetized with a fine bit is extended, so that the toner layer on the developing roller is easily thinned, and the density irregularities, etc., caused by the fluctuations of the magnetic field and the thickness of the toner layer are reduced. Further, the uniform holding and carrying of the toner in a thin layer state can be carried out by using an elastic blade, etc., and a developing gap can be made small, so that a developing electrode can be disposed very near to an electrostatic latent image. Therefore, an image having high resolution and high-definition is obtained.

IPC: C07C63/24
Filed: 1993-06-30
Abstract: PURPOSE:To provide a method for producing high-purity isophthalic acid in which a waste liquid in a step for purifying crude isophthalic acid is remarkably reduced; the cost of the waste liquid treatment is reduced and both the product yield and the energy unit requirement in the process for producing the high-purity isophthalic acid have been improved. CONSTITUTION:An m-dialkylbezene is oxidized with molecular oxygen in the liquid phase in an acetic acid solvent containing an oxidation catalyst composed of a heavy metallic compound and a bromine compound in a liquid-phase oxidation reactor 1 and the resultant liquid oxidation effluent is then cooled to separate crude isophthalic acid, which is subsequently dissolved in hot water to carry out the catalytic hydrogenating treatment in a catalytic hydrogenation reactor 12 by using a catalyst composed of a group VIII metal of the periodic table in the presence of hydrogen. The resultant reactional solution is then cooled to crystallize the high-purity isophthalic acid with crystallizers 14 and 15 and separate the crystal with a solid-liquid separator 17. In this method, the separated mother liquid obtained in separating the crystal of the high-purity isophthalic acid with the solid-liquid separator 17 is heated in the first heat exchanger 2 under pressure to evaporate the water. Thereby, the separated mother liquid is concentrated within a range so as not to crystallize the isopthalic acid and the concentrated separated mother liquid is filtered through a filter 3 having <=15mum average pore diameter and then returned to the liquid-phase oxidation reactor 1.
