Title: External character pattern management
Inventor: FUJITA TOMOKO
IPC: G06F17/21
Filed: 1992-10-16
Abstract: PURPOSE:To reduce the memory capacity required for external character pattern management by managing the frequency in use of each external character without a counter. CONSTITUTION:Each time an external character pattern in an external character pattern memory 15 is referred to, the use entry in an external character pattern management memory 16 corresponding to the external character pattern is moved to the position of the highest priority level in this memory 16, and lower entries whose priority levels are higher than that of the use entry are pushed up by one. Then, plural entries are always arranged in the order of the frequency in use. Therefore, the frequency in use of each external character is managed without a counter to reduce the memory capacity, and a user is released from evils such as restrictions on the frequency in use of external characters due to overflow of the counter and the complicated control which prevents the evils.

Abstract: PROBLEM TO BE SOLVED: To enhance follow-up performance of furnace temperature control in a gas combustion furnace by omitting prepurge, or shortening the time for performing prepurge before igniting a burner when an ignition demand signal is outputted to the burner. SOLUTION: When shut-off valves V1, V2 are controlled to close so as to extinguish a burner 3, a routine for determining whether prepurge of an interior of a furnace body 2 is omitted or is carried out for a shortened time is executed on the basis of change in internal pressure between the shut-off valves V1, V2 in a predetermined time after the internal pressure is adjusted to a predetermined pressure. By this routine, in the case that an ignition demand signal to the burner 3 is inputted to a control circuit 15, only when each routine has decided total omission of prepurge or shortening of the time for prepurge from a starting time upon extinguishment of a gas combustion furnace 1, execution of prepurge is omitted or prepurge is executed for a reduced time and the burner 3 is ignited.

Title: Image forming device
Inventor: YOSHIYAMA MASATOSHI
IPC: G03B27/73
Filed: 1989-10-26
Abstract: PURPOSE:To uniformize an amount of correction for a color picture by adjusting an amount of light with which a photosensitive recording medium is irradiated from a subexposure means, according to the type of a filter which the subexposure means selects. CONSTITUTION:The subexposure means M4 just irradiates the photosensitive recording medium M1 with color light independently of image exposure with light reflected from an original. Therefore, the latent image of an original is formed on the photosensitive recording medium M1 before or after or at the same time that the exposure carried out by the subexposure means M4. At the time of the subexposure, a means M5 for adjusting an amount of light adjusts an amount of light with which the photosensitive recording medium M1 is irradiated from the subexposure means M4, according to the type of the selected filter M3. Thus, an amount of the correction of tone for the final color picture is made uniform irrespective of a difference in tone.
