Title: Image recording method
Inventor: SHINADA HIDETOSHI
IPC: H04N1/04
Filed: 1985-10-12
Abstract: PURPOSE:To record document information in a prescribed area in appropriate size by previously setting up a main scanning area and a sub-scanning area whose size are larger than document size to be recorded. CONSTITUTION:The main scanning area based upon a rotary polygon mirror 7 and the sub-scanning area based upon a galvanomirror 12 are set up to an area 51 slightly larger than a proposed recording area 50 having the maximum size. The setting of the area 51 can be attained by increasing the effective vibration angle of the polygon mirror 7 and also increasing the inclined range of the galvanomirror 12. To record an image on a film, a recording area is analysed on the basis of document size MS and resolution RD and an ON/OFF signal LM corresponding to the recording area is applied to an optical modulator 2 in the main scanning. Consequently, the area of main scanning can be specified on the film F.

Filed: 1987-09-10
Abstract: PURPOSE:To improve safety in a combustion type heating device having electric control by prohibiting the restarting of the operation of a combustor even when the rotation of a combustion air blast motor is temporarily stopped. CONSTITUTION:The operating condition of a combustion air blast motor 13 is inputted into a microcomputer 17 as the output of a housing pulse generator 14 while being monitored one by one to enable a fuel pump 11 to be driven only when the output of the pulse generator 14 is normal. Even if a driving output is given to the blast motor 13, when pulses less than a reference period are not detected in an input 47, the fuel pump 11 is stopped while stopping an operation. By this structure, abnormal combustion, etc., can be prevented, improving safety.
