Title: Image forming device
Inventor: NISHIZAWA KATSUHIKO
IPC: G03G21/14
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To positively prevent a latent image ghost without necessarily prolonging FCOT (time spent until an image is output since the issuance of a print-out command) to the maximum allowable extent by a preexposure. SOLUTION: When a preexposure before the formation of an image is performed, the quantity of light of a laser beam to be emitted from a laser diode is increased over monitoring after rotating a polygon mirror (a). If the quantity of light of a laser beam is increased to such an extent that a minimum quantity of light which is detectable through a synchronous detector is reached, T1 of (C) and a horizontal synchronous signal from a synchronous detector are generated (b). The preexposure is initiated at the point of time when this first horizontal synchronous signal is generated. During the preexposure, an image forming area is subjected to a light exposure by controlling the quantity of light of a laser beam independently for the image forming area on a photosensor and another area.  Thus it is possible to surely prevent a latent image ghost from being generated without prolonging a process time.

Abstract: PROBLEM TO BE SOLVED: To distribute received signals to plural pieces of connected equipment and to control one reception terminal through plural pieces of control equipment by discriminating control signals to be inputted, deciding priority and outputting the control signals according to this priority. SOLUTION: In order to avoid the collision of control signals from plural simplified control terminals 300, the priority of the simplified control terminals 300 is stored in a non-volatile RAM inside a control microcomputer 160.

Abstract: PURPOSE:To make it possible to maintain food under a good condition by emitting warning, for example, when a difference in temperature between the upstream side of cool air and the downstream side thereof is larger than a predetermined value so as to control the difference in both temperatures to have a value smaller than a predetermined value. CONSTITUTION:The temperature within a freezing chamber 21 cooled by cool air from a cooling part 23, which is forcibly blasted, is controlled so that the temperature within the freezing chamber 21 maintains a set temperature range under the control of a control circuit 5. In a case where a large quantity of foods are accommodated in the freezing chamber 21, the difference in temperature detected by an upstream side temperature sensor 1 and a downstream side temperature sensor 17 becomes larger than a predetermined temperature difference. This extraordinary temperature difference is judged by a calculation made by a control circuit 5, whereby the control circuit 5 drives an alarm 15 and a warning display is carried out from the alarm 15. When the temperature difference detected by the upstream side temperature sensor 1 and the downstream side temperature sensor 17 is more than the predetermined temperature, the temperature difference is controlled to decrease within the predetermined temperature.
