Title: Fixing roller
Inventor: MACHIDA HIDENORI
IPC: H05B3/00
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To decrease the rising of the temp. of end parts with self-control and to make the temperature distribution of the surface of a roller uniform by making a heat generating layer made of a material having a positive resistance temperature coefficient, electrically dividing the heat generating layer into at least three to more add-number heat generating parts in the axial direction of the roller and electrically connecting the heating generating parts in parallel. SOLUTION: The heat generating layer 14 is made of the material having the positive resistance temperature coefficient and electrically divided into three heat generating parts 14a-14c in the axial direction of the roller. When electrodes 15a and 15c are connected and electrodes 15d and 15d are connected as well, these three heat generating parts 14a-14c are connected in parallel. Therefore, the heat generating layer 14 is made of the material having the positive resistance temperature coefficient, so that when the rising of the temp. in the end parts occurs, the resistivity of the heat generating parts which are located in the end parts and raised in the temp. is made higher than that of the heat generating part 14b in the central part.  Therefore, when the rising of the temp. in the end parts occurs, calorific values in the end parts become lower than those when the temp. of the roller is uniform. In other words, the self-control is executed to make the temp. of the roller uniform.

Title: Lens barrel
Inventor: MITO HIROSHI
IPC: G02B7/02
Filed: 1978-08-23
Abstract: PURPOSE: To achieve simpler construction and easier production without using double helicoids by restricting the rotation of an aperture device by the use of the lens-barrel moving in the axial direction when rotated.  
     CONSTITUTION: An aperture device 9 is provided turnably with restriction of its axial movement behind the moving lens frame 5 on the inner side of a stationary barrel 1 having a cam groove 2, relief groove 3 and straight groove 4. As a operating ring 7 is rotated, the lens barrel turns the cam guide piece 6 which is held fitted in the groove 8 and the frame 5 moves in the axial direction while rotating along the groove 2, thus performing the same operation as that of rotary helicoids. In this case, the device 9 will not rotate because of the engagement between the pin 10 and groove 4 and only the movement in the axial direction is accomplished together with the frame 5 thus the aperture operation system operates in the manner similar to that of rectilineal helicoid system. In addition, the rear lens frame 11 moves axially together with the frame 5, whereby distance control is accomplished.

IPC: H05K3/46
Filed: 1995-04-27
Abstract: PURPOSE: To provide a resin composition which can give a non-flow prepreg without using any modified resin by adding 2,4-diamino-s-triazine to a mixture comprising a thermosetting polyimide resin and an epoxy resin. CONSTITUTION: 2,4-Diamino-s-triazine is added to a mixture comprising a thermosetting polyimide resin and an epoxy resin to obtain a thermosetting polyimide resin composition. This composition is dissolved in an organic solvent to form a varnish, a fibrous base is impregnated with the varnish, and the resin is cured by heating to stage B to obtain a prepreg. Although a resin composition of this kind (e.g. a resin composition formed by mixing a thermosetting polyimide resin with an epoxy resin, dicyandiamide and a modified resin) has controlled resin flow, it has drawbacks that the heat resistance is lowered, and the modified resin is eluted or swollen by chemical treatment. this composition can give a uniform prrepreg having low resin flow without using any modified resin.
