Patent JP-H08166709-A (JP)
Title: Image forming device
Inventor: NISHIO YUKITO
IPC: G03G15/34
Filed: 1994-12-14
Abstract: PURPOSE: To reduce the number of composing members required for image formation and to reduce a size and cost of the device. CONSTITUTION: This device is equipped with a doctor blade 4 for regulating an amount of toner on a toner carrier 3, which is in contact with the frictionally electrified toner 1 in a toner storage tank 2 and holds the toner 1 on it. A voltage for selectively electrifying the toner 1 is supplied to the doctor blade 4 via an electrification control unit 10. Thus, the amount of the toner 1 held on the toner carrier 3 is regulated and, at the same time, the toner 1 is electrified to a specific polarity with potential which is higher than or equal to the frictional electrification. An electrostatic latent image is formed from the selectively electrified toner 1, and the image is transferred onto properly-carried foam 5 by causing the toner 1 to fly by means of electric field generated by a voltage applied by an opposite electrode 6 arranged opposite the toner carrier 3.  Thus, the image by the toner 1 is formed on the foam 5.

Title: Manufacture of silicone rubber connector having spongy support
Inventor: AKAHA SUSUMU
IPC: B29C44/00
Filed: 1990-11-16
Abstract: PURPOSE:To prevent core material from being offset and becoming wavy and make it possible to form the connector concerned even having the thickness of 2-3mm or more by one operation by a method wherein a floating mold is used for thermoforming spongy support. CONSTITUTION:By thermoforming core material 2 pinched by support material 1' with a floating mold 3, the mold 3 is brought into close contact with the material 1 since the early heating stage, resulting in eliminating the difference between the times starting from the heating of the top side and the under side support materials 1' and the ununiform heating of the support materials and performing the thermoforming up to the necessary thickness under the condition that the material 1 is brought into close contact with the mold 3 by the expanding force of the support materiel 1' developed by heating. At this time, since the support material 1' is expanded in the form of sponge by the gas generated by the decomposition of expanding agent blended with the support material 1', the expanding force is set to be larger than the load of the floating mold 3 so as to push up the mold 3. Further, by adopting silicone rubber based material as the support material 1', the joining between the core material 2 and the support material 1' is satisfactorily performed at tire thermoforming.

IPC: H01J9/22
Filed: 1988-12-08
Abstract: PURPOSE:To obtain a satisfactory coat even by the simultaneous burning of first an second coating film layers by forming the first coating film layer by a coating solution containing a solid component of superfine particles, a binder of highly viscous cellulose nitrate of a specified ratio, and a solvent. CONSTITUTION:A glass tube inner surface is coated with a coating solution containing a solid component of superfine particles to form a film forming material, a binder of highly viscous cellulose nitrate of less than 10wt.% to the solid component, and a solvent followed by drying to form a first coating film layer. The first coating film layer is further coated with a coating solution containing a phosphor having an average particle size of 1-4mum, the binder, and the solvent followed by drying to form a second coating film layer. The first and second coating film layers are simultaneously burnt. The cellulose nitrate of the binder contained in the first coating film layer has the function of making the solid component adhere to a glass tube satisfactory even if its content is reduced, because of its high viscosity, and enables the satisfactory film formation of the first coating film layer. Further, as the amount of the binder contained in the first coating film layer is significantly reduced, the binder in the first coating film layer can be sufficiently removed in the following burning process.

Title: Variable damper
Inventor: YASUI HIDEKAZU
IPC: F16F9/12
Filed: 1993-12-13
Abstract: PURPOSE:To optionally and easily adjust a torque to be generated. CONSTITUTION:A variable damper 1 has fixed plates 9a, 9b and movable plates 8a, 8b which are rotated interlockingly with first and second rotary shafts 5a, 5b. Gaps P to U are optionally adjusted by an adjusting bis 18. When the movable plates 8a, 8b are rotated in the state that gaps P, R, T are respectively equal to gaps Q, S, U, viscous fluid existing in the gaps P to U shows small shearing resistance, generating a small torque. When the rotaion is performed in the state that the gaps P, R, T is narrower than the gaps Q, S, U, the viscous fluid existing in the gaps P, R, T shows large shearing resistance, generating a large torque. The torque generated can be varied by means of the adjusting bis 18.
