Title: Production of carrier for electrophotography
Inventor: NAKAMURA YASUSHIGE
IPC: G03G9/113
Filed: 1991-03-13
Abstract: PURPOSE:To obtain the carrier for electrophotography which is stable in electric resistance and electrostatic charge characteristics over a long period of time and has good printing quality by coating the surface of magnetic powder with an epoxy resin and UV functional Lewis acid salt and irradiating the coating with UV rays to cure the coating liquid. CONSTITUTION:The surface of the magnetic powder as a core material is coated with the epoxy resin and the UV functional Lewis acid salt. The coating liquid is thereafter irradiated with the UV rays and is thereby cured. The core material may be magnetite and ferrite. Epoxy groups of a glycidyl ether type and alicyclic type are used as the epoxy resin. The Lewis acid salt includes the diazonium salt of Lewis acid and sulfonium salt of Lewis acid as the Lewis acid salt. Sensitizers of a carbonyl system and nitrogenous system may be used in order to improve UV functionability. The generation of the peeling or wear of the resin film on the carrier is substantially prevented in this way.

A resist 17 for protecting the so-called CdSe thin-film for protecting a section required for manufacturing the thin-film transistor is deposited and formed onto the upper surface of the CdSe thin-film 16. The whole sample is introduced into a sputtering device, and an unnecessary section in the CdSe thin-film 16 is removed through a dry etching process under a plasma-changed argon gas atmosphere at 1X10<-2>Torr. The CdSe thin-film 16 coating the side surface of a resist 14 for lifting off the gate insulating film and one part of the gate insulating film 15 are gotten rid of at the same time, and the side surface of the resist 14 for the lift-off is exposed.

Filed: 1994-03-18
Abstract: PURPOSE:To transfer a yarn being taken up on a full bobbin to an empty bobbin in contact with a drive roller, and perform stably the yarn replacement in a surface drive type winding machine by restituting the rotating speed of a retarded godet roller to the steady speed. CONSTITUTION:When a bobbin 4 under the takeup motion becomes full, a yarn replacing motion is commenced. Thereby a godet roller 12 is retarded, and an empty bobbin is put in an approach run by an approach run roller 6 so that the surface velocity becomes the steady takeup speed or a speed some higher that it. Then a turret arm 2 is rotated so that a spiral bobbin is separated from a drive roller 5 and also the empty bobbin in approach run is directed to it 5, and thereby transfer to the empty bobbin is conducted. The rotating speed of the retarded godet roller 12 is restituted to the steady speed. Thereby the relative speed of the godet roller 12 with the full bobbin can be maintained constant, and stable yarn replacement can be performed.

Filed: 1978-04-25
Abstract: PURPOSE:To inform the speed reduction of a vehicle to the succeeding one not only when the former vehicle is decelerated by its brake but also when the vehicle is decelerated by its engine brake, by lighting on a lamp. CONSTITUTION:A diaphragm 3 is airtightly supported by a cover 1 and a housing 2 so that two chambers A, B are defined. A throttle member 8 is fitted in a rod 6 provided at the central part of the diaphragm 3 and is connected to the chambers A, B through a hole 7 of the rod 6.

Title: Temperature control apparatus of heating furnace for analysis
Inventor: HARIGAI TETSUZO
IPC: G01N25/00
Filed: 1990-02-27
Abstract: PURPOSE:To prevent the rapid increase of the temperature of a heating furnace by comparing the changing speed of a current which is supplied to the heating furnace with a reference value, and stopping the current supply to the heating furnace when the current increasing speed exceeds the reference value. CONSTITUTION:A sample is contained in a sample cell 2, and a standard material is contained in a standard-material cell 3. Then an apparatus is operated. A current which realizes a temperature increasing speed that is set in a temperature-increasing-speed setting device 13 is made to flow into a heater 4 through a current adjusting device 9 with a PID control circuit 12. In this way, endothermic or exothermic reaction occurs in the cell 2 based on the composition. The temperature difference between the cells 2 and 3 is detected with thermocouples 5 and 6. When the temperature of the heating furnace 1 cannot be detected because of the wire breakdown of the thermocouples 5 and 6 and the like, the current is rapidly increased with the adjusting device 9 with the circuit 12 so that the difference in temperature signals from the setting device 13 and the thermocouple 16 becomes zero. Therefore, the changing speed of the current detected with a differentiating circuit 14 becomes large and exceeds the value of a maximum-current-increasing-speed memory circuit 15. A breaker 11 is turned OFF with comparator circuit 16, and the current to the heater 4 is cut OFF.

Title: Heat transfer-type printer
Inventor: YANAGIDA TOMOHIKO
IPC: B41J33/38
Filed: 1984-03-16
Abstract: PURPOSE:To enable heat sensitive transfer printing at high speed through reciprocal printing by driving an ink ribbon with a thermal head in an interlocking manner in both forward path and return path at the time of a shift of the thermal head to carry out printing action in both directions. CONSTITUTION:A ribbon cassette 10, 11 and a thermal head 1 are mounted on a carriage 9 arranged on an axis 8 in a freely movable manner. The driving force of a timing belt 13 is transmitted by a pulley 36 to a drive gear for a ribbon- winding shaft 33 on both sides and then to a stopper-engaging gear 34 and a ribbon winding shaft 32 through a slide board 40. Therefore, a counterclockwise force is applied to the stopper engaging gear 34 on both sides. However, because of the intermeshing of a stopper 35 to the right-side stopper-engaging gear 34, the right-side stopper-engaging gear 34 is forced to stop its rotary motion. The drive gear for a ribbon-winding shaft 33 is prevented from transmitting its rotary force by a slip between the slide board 40 and the stopper-engaging gear 34. That is, when the carriage 9 moves to the right, only the left-side ribbon- winding shaft 32 turns counterclockwise to perform ribbon winding.
