Title: Image forming method
Inventor: FUJII HARUO
IPC: G03G13/09
Filed: 1983-07-18
Abstract: PURPOSE:To enable transfer to ordinary paper in an electric field, to make a corona discharge means unnecessary, and to enable polychromatic recording by using developer prepd. by mixing an electrically conductive magnetic carrier with an insulating toner. CONSTITUTION:A developing device is composed of a magnet 6' and a hollow cylindrical member 5' for transferring a toner, and a developer consisting of an insulating toner 14 and an electrically conductive magnetic carrier 13 is used. A recording medium 11 composed of a transparent electrode substrate 1 and a photoconductor 2 is set at the recording position 12. At a part C irradiated with light 9, voltage applied from a power source 10 reach a position close to the developer through the layer 2. The toner 14 is positively charged, and the carrier 13 is negatively charged, yet since the carrier 13 is electrically conductive, positive charges are injected through the member 5' to cancel the negativity of the carrier 13. The toner 14 is made easily separable from the carrier 13, and the part C attracts the toner 14 to stick it. The carrier 13 is attracted by the magnet 6', so it does not stick to the medium 11.

Title: Pressure developing device for image forming device
Inventor: AIKAWA MASARU
IPC: G03D13/00
Filed: 1990-05-21
Abstract: PURPOSE:To reduce pressurizing force, to moderate impact at the time of starting and finishing pressurizing and to miniaturize a device by using a pressurizing member in which plural globular bodies are disposed. CONSTITUTION:After image exposure is executed to a photosensitive film which is coated with a specified microcapsule, the film is superposed on a transfer paper, which are pressurized by the pressurizing member so as to form the image on the transfer paper. In such a case, plural holes are formed on a sleeve 101, and pressurizing is performed by using a member A obtained by disposing the globular bodies 102 to the holes. Since an area for pressure development becomes small by thus doing, the impact by the end of the transfer paper at the time of starting and finishing the pressure development becomes small. It is desirable that the globular body 102 does not pressurize a member to be pressurized when the member A does not rotate and a developing width by the globular body 102 is changed in accordance with the width of the transfer paper.

Title: Manufacture of glass light emanative element
Inventor: FUJII KIYOSUMI
IPC: G02B5/02
Filed: 1991-06-03
Abstract: PURPOSE:To heighten uniformity of light emanation in the case of manufacturing a light emanative element forming in such a way that incident light from the edge surface can be diverged outside from the side surface being the diffusing surface. CONSTITUTION:After mechanical roughened surface forming processing such as grinding, polishing and so on is carried out on the side surface of a glass bar, sharp recess/projection is formed in smooth recess/projection by means of heat treatment. It is preferable to give temperature gradient so as to be lowered gradually in the element length direction while keeping the light incident edge surface side at a high temperature. Since a degree of irregular reflection is still conspicuous only by means of the mechanical roughened surface forming processing, the temperature gradient shows a tendency to lower rapidly after light is diverged intensely in the side surface part close to the light incident edge surface, but according to this method, intensity of emanative light can be uniformized in the element length direction to a high degree.

IPC: C30B11/04
Filed: 1986-06-05
Abstract: PURPOSE:In upright Bridgman method, to make it possible to carry out high- precision vapor pressure control and to produce single crystal having improved stoichiometric properties and few defects, by using a device equipped with a storage chamber for vapor pressure controlling component element. CONSTITUTION:A raw material container 14 is charged with CdTe, Cd having six nine purity is fed to a storage chamber 11 for vapor pressure controlling component element, air in a reaction tube 13 is replaced with high-purity Ar, evacuated to <=10<-3>Torr and sealed. Then, T1, T2 and T3 are adjusted to given temperatures, respectively, the reaction tube 13 is lowered at a given speed to prepare CdTe single crystal. By this method, since the storage chamber 11 is set below a growing chamber 10 and they are communicated through a small hole 12, the existing area of a condensation phase (or melting phase) will not spread even if the vapor pressure controlling element is melted or boiled and temperature in a narrow zone is detected to carry out high-precision temperature control, namely vapor pressure control. Consequently, single crystal having improved stoichiometric properties and few defects can be produced.

Title: Torque transmission device
Inventor: HAYASHI KANJI
IPC: F16D7/02
Filed: 1986-06-06
Abstract: PURPOSE:To prevent the transmission of excessive torque to a roll driving system during the leveling of a sheet by installing a torque control device consisting of a screw and nut as well as a liquid pressure cylinder which can hold these two members in press contact with each other by optional pressing force to the roll driving system. CONSTITUTION:A liquid pressure is supplied from an oil feed pipe 18b to a head side of a piston 17 and the liquid pressure in a cylinder chamber 16 on a rod 11b side is released to bring the screw 11a into press contact with the nut 12a at the time of leveling a material to be leveled by means of work rolls 2a-2i installed zigzag. The max. torque of the work rolls 2a-2i necessary for leveling the material to be leveled is, at the same time, transmitted from a distribution gear 5 to a spindle 4 via the nut 12a and the screw 11a. The liquid pressure is so set as to induce a relative slip between the screw 11a and the nut 12a and to generate the pressing force there between when the excessive frictional torque occurring in the speed difference between the roll 2a, etc., and the surface of the material to be leveled acts on the set torque during the leveling. The energy generated by the excessive torque is thus absorbed by the axial displacement of the piston 17.
