Abstract: PURPOSE:To securely hold a photosensitive body and obtain an image of high picture quality and to facilitate maintenance such as the replacement of a photosensitive body by tapering either or both of the engagement parts of the end parts of a photosensitive drum and flanges which hold the photosensitive drum. CONSTITUTION:This device has the flanges 122 and 123 which hold the photosensitive drum 121 by engaging the end parts of the photosensitive drum 121 and a photosensitive drum guide 138 which guides the photosensitive drum 121 when the photosensitive drum 121 is inserted or extracted and normally form a gap with the photosensitive drum.

Abstract: PURPOSE:To make it possible to detect the fine thinning-down of a pattern and the like as well by a method wherein a comparison of a light field and a dark field is performed, the dark-field image part is removed from the light- field comparison part by being binarized. CONSTITUTION:An image formed using dark-field illumination sources 5 and 6 is inspected using a dark-field comparator 14 by the instruction of a light and dark-field controller 9. At this time, a dark-field inspected region is retained as a binary image by a binary circuit 13. An image formed using light-field illumination sources 7 and 8 is inspected using a light-field comparator 12 by the instruction of the controller 9. An inspected part in a dark field is removed from the result of the comparator 12 by an XOR circuit 15 and an inspected result unitizing the respective characteristics of a light field and the dark, field is outputted from a result output device 16.

Title: Load controller
Inventor: SHIMOZAWA MASAKI
IPC: H02J1/00
Filed: 1993-12-07
Abstract: PURPOSE:To prevent a load current over a rated level, by reducing a voltage for a controller to a given level through a short circuit of its power supply, and resetting a microcomputer when a plurality of relays are improperly turned on at the same time. CONSTITUTION:A plurality of relays 2 and 3 should not be turned on concurrently, but if the relays 2 and 3 are improperly turned on concurrently and a plurality of loads are operated at the same time, a short circuit in a power supply 8 for the control unit is caused by a short-circuit transistor 6. Then, the voltage of the power supply 8 is reduced. The voltage of the power supply 8 is lowered to a given level (for example -15V) so that a microcomputer 1 is reset by a reset circuit 7. Consequently, concurrent driving control, i.e., concurrent plural continuity control, for the loads is stopped, and a load current over a rated level can be prevented.

IPC: H04N9/64
Filed: 1994-12-09
Abstract: PURPOSE: To perform appropriate luminance correction at any luminance by adding and subtracting digital RGB signals attenuated beforehand and the digital RGB signals attenuated corresponding to luminance correction signals. CONSTITUTION: ROMs 61-63 are a kind of conversion tables for constantly attenuating the respective digital RGB signals after A/D conversion.

Inventor: ASANUMA SHINKICHI
IPC: B60G7/02
Filed: 1986-12-24
Abstract: PURPOSE:To aim at enhancing the running performance, in a suspension device for a wheel mounting type vehicle, by using a drive force and a brake force exerted to wheels so as to change the geometry of suspension. CONSTITUTION:In such a condition that a spool valve in a flow control means 10 disposed in a piston 10 between two chambers 7, 8 in a cylinder welded to the bifurcated front end part of an upper arm AU, is actuated so as to open a communication passage 9, when a drive or brake force FUT or FUB acts upon a king pin pivot point AUO on the upper arm AU, the arm in its entirety is pressed toward the front side RR. Thereby, the pressure differential is effected between the chambers 7, 8. In this phase, when the flow control valve 10 opens and closes the communication passage 9, the power relationship between the force and the reaction force of a spring S causes the upper arm AU to move in the direction of the arrow FR or the direction reverse to the latter so as to increase or decrease the caster angle. Thus, the suspension geometry may be changed to enhance the running performance.
