Patent JP-H07261291-A (JP)
Title: Image forming device
Inventor: NISHIDA IKUO
IPC: G03B27/72
Filed: 1994-03-23
Abstract: PURPOSE:To perform exposure in accordance with the length of an original and to eliminate needless exposure by detecting reflected light from an original surface along a scanning direction by an exposure scanning means and discriminating the presence or absence of the original in the scanning direction based on the level of the detection signal. CONSTITUTION:A CPU 10 judges the presence or absence of the original in the midst of scanning based on the output level of a 1st sensor 51. In the case of judging that the original does not exist, the CPU 10 controls a lamp regulator 11 to put out a lamp 123 and turns off an electrifying transformer 12, then an erasing LED 53 is lighted to make the surface potential of a photoreceptor drop. Thus, in the case the size of the paper is A4 and the size of the original is shorter than A4, the lamp 123 is not lighted more than the size of the original, whereby a user is prevented from being dazzled. Besides, since the electrification of the non-image part of the photoreceptor is lowered by the action of the erasing LED 53, the excess consumption of toner is restrained and an excess solid black part is not formed on an image on the paper.

Abstract: PURPOSE:To treat waste water by mixing a high-b.p. hydrocarbon into waste water contg. a chlorine org. solvent, dissolving the chlorine org. solvent into the high-b.p. hydrocarbon and then separating the layer of the high-b.p. hydrocarbon by an appropriate method. CONSTITUTION:A high-b.p. hydrocarbon such as liq. paraffin is mixed into waste water contg. chlorine org. solvents such as dichloroethane, trichloroethylene, etc., to dissolve the chlorine org. solvents into the high-b.p. hydrocarbon. The liq. is introduced into a separation vessel and separated into the upper layer of the high-b.p. hydrocarbon having absorbed the chlorine org. solvents and the lower water layer by utilizing the difference in sp.gr. The water layer separated by the operation can be discharged as safe water, however the same treatment, if necessary, is repeated several times to obtain water which can be more safely discharged. Meanwhile, the high-b.p. hydrocarbon layer is distilled in a distillation tower and fractionated into the chlorine org. solvent and the high-b.p. hydrocarbon. The latter is reused. Consequently, the treatment can be carried out efficiently and safely at low cost.

Title: Heater control device for air-fuel ratio sensor
Inventor: IDE KOJI
IPC: G01N27/409
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a heater control device for an air-fuel ratio sensor, capable of performing preheating so that air-fuel ratio feedback control can be positively executed from immediately, after starting an engine. SOLUTION: When a receiver receives a radio signal from a transmitter held by a driver, a distance R between a vehicle and the driver is detected (step 100). Then, whether or not preheating is to be performed is discriminated. When preheating is performed, a target temperature Tc is set in response to the distance R between the vehicle and the driver, and the current carrying quantity to a heater is controlled so that the sensor temperature T reaches a target temperature Tc. For example, when the distance R between the vehicle and the driver is such that R2<=R<R1 (step 108), the target temperature Tc is set to the lowest temperature T1. When the distance R between the vehicle and the driver is such that R3<=R<R2 (step 112), the target temperature Tc is set to T2(>T1).
