Filed: 1991-07-09
Abstract: PURPOSE:To obtain the process for production of the patterned and coated steel products formed with varicolored patterns having depth and softness by respectively dropping coating materials of different colors having high viscosities randomly or at specified intervals onto the coating steel products, and applying a clear coating material wet on wet over the entire surface before the coating materials do not cure yet and allowing the coating films to cure as the varicolored patterns. CONSTITUTION:Solvent type colored coating materials or water-base colored coating materials, from which pigments are removed, are used for the finish clear coating material. The primer colored coating material and the finish clear coating material having affinity and compatibility with each other are preferred in order to form the varicolored patterns by bleeding. The primer colored coating material A having the high viscosity is dropped onto the smooth coating steel products 1 and in succession, the primer colored coating material of the different color having the high viscosity is dropped thereto, respectively from the nozzle 2. The finish clear coating material C which easily dissolves the primer colored coating material is then applied wet on wet over the entire surface by a spray 3 before the primer colored coating material cures to form the varicolored patterns 4. The coating films are then allowed to cure. The patterned and coated steel products having the varicolored patterns which are not distinct in the boundaries are thus produced.

Title: Image forming apparatus
Inventor: KUZUMI TOORU
IPC: G03G15/01
Filed: 1994-06-28
Abstract: PURPOSE:To provide multicolor images with high quality in which the occurrence of transfer failure and uneven transfer is prevented by changing the transfer current or the transfer voltage optimum for each toner image of each color in cyclically and carrying out the transfer by a transferring means in the case respective toner images of two or more colors formed on an image carrier are transferred to a transfer material at one time. CONSTITUTION:A toner image with a second color is formed on a photoconductive drum 1, which is an image carrier, independently of a toner image with a first color. The transfer current to be applied to a transfer corona charging apparatus 8 is switched to be I1 and I2 cyclically and the switching frequency is set to be high frequency, for example, 2kHz. Voltage switching necessary to apply the transfer current I1 and I2 is done by using overlaying electric power sources of AC power source 10a and D.C. power source 10b as a power source for the transfer corona charging apparatus 8. The sign 9 shows a rated-current circuit to control the transfer current to be the prescribed values mentioned above. As a result, both toner images with the first color and the second color can be transferred simultaneously at 90-99% transfer efficiency, which may be practically the maximum transfer efficiency. In that case, the toner images of these two colors are formed independently on a transfer paper.

Title: Rotor of dynamo-electric machine
Inventor: FUJI TAKAKUNI
IPC: H02K1/22
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To reduce torque ripple without dropping the total torque of a dynamo-electric machine including a rotor having a salient pole, and reduce the vibration and the beat of the rotor. SOLUTION: Salient poles 24a and 24b, are divided and the magnetic path formed by the salient poles 24a and 24b is narrowed to lessen the maximum value of torque generated by being drawn by a rotating magnetic field, and also the average torque at the position of an optional rotor 14 is raised or maintained by generating torque in order in the salient poles 24a and 24b. Moreover, the plus torque by which the salient poles 24a and 24b are drawn closer to the magnetic field and minus torque by which they are drawn apart are made to work on it in order so as to cancel each other thereby preventing sudden torque drop. As a result, the maximum torque of the rotor 14 at optional timing is dropped, and the minimum torque is raised, and torque ripple is made small while raising or maintaining the average torque at maximum, whereby vibration or a beat decreases.

Filed: 1989-07-03
Abstract: PURPOSE:To uniformize a copying density by detecting the light transmissivity of an original and controlling an amount of irradiation used for exposing a photosensitive material. CONSTITUTION:A detecting means 31 detects the light transmissivity of the original 2; a light emitting diode 32 is positioned so that light emitted from it is transmitted through the original paper 2 to be made incident on a light receiving diode 33; the amount of light made incident on the light receiving diode 33 corresponds with the light transmissivity of the original 2; a detecting signal V1 whose level varies with light transmissivity is supplied to a control circuit 35.
