IPC: G06T1/00
Filed: 1994-09-20
Abstract: PURPOSE: To attain the detection of trace information at a level stable at all times by adding trace information having been stored in a memory to an original after trace information having been described onto the original before is deleted. CONSTITUTION: The major parts of a digital color copying machine are made up of an image reader section 100 for reading an original image and a copying section 200 for reproducing read image data of an original onto copy paper. The configuration of the reader section 100 is similar to that of a conventional device and an image of an original surface irradiated by a scanner section 10 being a component of the reader section 100 is photoelectric-converted. The copying section 200 applies gamma correction corresponding to the gradation characteristic of a photoreceptor to gradation data by a print head section 31 to emit a semiconductor laser beam. The emitted light intensity is revised and the photoreceptor drum 41 is exposed by the reflected light 39 to use a charger 43 for uniform charging, thereby causing an electrostatic latent image of the original on the drum 41. Then the latent image is developed and the obtained toner image is transferred to copy paper on the transfer drum 51 by using a transfer charger 46.

Title: Braking force control device
Inventor: KITAZAWA KEIICHI
IPC: B60T8/26
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To automatically limit the operational input of braking caused by driving, so that an actually applied braking pressure does not cause a vehicle to spin or drift out. SOLUTION: The friction coefficient (μ) of a road surface is estimated through operations from operational control input data and vehicle behavior data, and when the output value of the friction coefficient (μ) is small, the braking pressure (pneumatic or hydraulic) applied to wheels in response to an operational input applied to a brake pedal is limited to a smaller one. Thus during travel on a slippery road surface, the braking pressure can be controlled automatically without making the driver conscious of it.

Abstract: PURPOSE: To simplify whole constitution and to inexpensively prevent the toner image on a transfer sheet from position-shifting by starting transferring the toner image on the transfer sheet after completion of holding the transfer sheet on the transfer drum by the transfer means. CONSTITUTION: The transfer of the first toner image is started after completion of attracting-holding the transfer sheet S on the transfer drum 2. Accordingly, the transfer drum 2 is rotated for one turn as the transfer sheet attract-holding process, so as to attain the attraction of the transfer sheet S from the beginning to the completion of attract-holding preceding to the toner image transfer, the first toner image transfer is started after the one turn, and moreover the respective toner image subsequent to the second color is successively multi- transferred. Thus, the transfer sheet S is completely held on the transfer drum 2, and passes through the transferring position of the transfer part at the same speed as the surface moving speed of the transfer drum 2 and the photoreceptor drum 1.  Therefore, the toner image is transferred to the transfer sheet S without any transfer irregularity, consequently the excellent image is formed.
