Title: Image forming device
Inventor: TANIMOTO KOJI
IPC: B41J2/44
Filed: 1989-01-31
Abstract: PURPOSE:To obtain the image of good quality by controlling the light emitting time of a light beam. CONSTITUTION:The density of the image obtained by developing a latent image formed on an image carrier (photosensitive drum) 30 is detected. In response to the density range of the detected image, the light emitting time of the light beam 64 for forming the latent image on the image carrier is made shorter, for example, when the detected density is high. Meanwhile, when the detected density is low, the light emitting time of the light beam 64 is made longer. Namely, the density of the developer of the latent image formed on the image carrier 30 is detected and the light emitting time of laser light 64 is controlled in accordance with the density. Thus, the image of good quality is formed without receiving the effect of the change of environment such as temperature and humidity.

Title: Manufacturing equipment for stem
Inventor: MATSUMOTO MITSUNOBU
IPC: H01J9/32
Filed: 1985-02-06
Abstract: PURPOSE:To enable the ignition of a head gas burner immediately before the start of production, by using a sheathed heater to perform automatic preheating for about 30min-1hr to obtain a temperature almost equal to that of no-object heating by a stem head gas burner. CONSTITUTION:An air cylinder 5 is put into operation through the action of a timer so that electricity supply electrodes 4 are placed into contact with two electrically supply rails 3 facing the electrodes 4. After that, preset electric power is applied to the electrodes 4 through the action of a timer signal so that the power is supplied to sheathed heaters 2 connected to the rails. Immediately before the start of production, the timer finishes acting, the electric power is cutoff, and electricity applied to the air cylinder 5 is also cutoff. After that, a stem machine head gas burner is ignited to start the operation of a stem machine. No-object heating is thus abolished. Since automatic preheating is performed as the stem machine remains stopped, energy is conserved.
