Abstract: PURPOSE:To execute a stable process control by providing a temperature detecting means so as to contact or to be adjacent to a photosensitive body, and calculating the light quantity of a laser beam at the time of forming an electrostatic image for detecting an image density, in accordance with a detected temperature. CONSTITUTION:A timing control circuit 8 selects an image signal supplying circuit 9 and forms an electrostatic latent image on the surface of a photosensitive body 5. When the circuit 8 selects an image signal generating circuit 10, an electrostatic latent image for detecting an image density is formed on the surface of the photosensitive body 5, based on a signal from the circuit 10, developed and becomes a reference toner image 17. In this case, a laser beam quantity calculating circuit 13 calculates a laser beam quantity in accordance with a detected temperature from a temperature detecting circuit 12 and output is to the circuit 10. Accordingly, the surface potential of the electrostatic latent image for detecting the image density is kept constant irrespective of a temperature variation. The toner image 17 is irradiated by a light source 10, and a signal corresponding to the image density of the toner image 17 is supplied to a toner replenishment control circuit 23 by an image density detecting circuit 20. In this way, a stable process control can be executed.

Title: Mos transistor
Inventor: SUMI TATSUMI
IPC: H01L29/78
Filed: 1989-04-06
Abstract: PURPOSE:To control avalanche breakdown of both high impurities concentration region and to enable high power supply voltage to be applied to by forming high impurities concentration region of source/drain so that it may not contact the isolation region of high impurities concentration. CONSTITUTION:A MOS type transistor is configured so that a high impurities concentration region 3 of source/drain may not contact an isolation region 2 of high impurities concentration. Thus, the source/drain region 3 is formed being away from the isolation region 2. Therefore, since both high concentration impurities region do not contact each other, a depletion layer is formed at a region between the high concentration regions to relax electric field even if a high voltage is applied to the drain region, thus controlling occurrence of avalanche breakdown.

Title: Stabilizer for discharge lamp
Inventor: YOSHIMURA SHIYUUHOU
IPC: H01F37/00
Filed: 1978-07-18
Abstract: PURPOSE: To raise an safety of a stabilizer by providing a leakage core between the coils connected in series with the other in a predetermined distance to a radial direction of a main core.  
     CONSTITUTION: A coil constituting a stabilizer is diveded into coils 3a to 3d wound around a main core l in a predetermined distanceand a plurality of leakage cores 4a to 4c for bypassing the intermediate pathbetween the main core 1 and the outer core 2 is interposed between the coils. Therefore, because the heat generated in the coils and main core 1 during operation is radiated to the exterior through the leakage cores 4a to 4d, the elevation of the temperature in the stabilizer is restricted. Because the coil is divided into several pieces the insulation resistance to voltage can be low. Whereby the safety for the stabilizer can be improved and the abnormal current generated by occurrence of the interlayer short-circuit in the coils can be reduced as well.

IPC: G07F9/10
Filed: 1994-04-26
Abstract: PURPOSE:To shorten the commodity cooling time in a commodity container shelf by opening fully a movable opening when the entire of the commodity container shelf and the commodity storage shelf are cooled. CONSTITUTION:When movable openings 17a, 17b are fully open, a part of cooling air returns to an evaporator 9 through a duct 16 and a commodity storage shelf 5 is cooled through the moving opening 17b and returns to the evaporator 9 through a lower movable opening 17a to cool the entire commodity container shelf 4 and commodity storage shelf 5. When the movable openings 17a, 17b are made narrow, the cooling air passes through mainly the duct 16 having less resistance and the amount of air passing through the movable openings 17a, 17b and entering the commodity storage shelf 5 is decreased to pre-heat the commodity storage shelf 5. When the movable openings 17a, 17b are closed, the cooling air passes through the duct 16 entirely to cool only the commodity container shelf 4. The energy is effectively saved by adjusting the movable openings 17a, 17b.
