Title: Liquid crystal display
Inventor: MATSUO SHOJIRO
IPC: G09F9/00
Filed: 1993-05-28
Abstract: PURPOSE:To reduce electric power consumption by emitting an ultrasonic wave, measuring positions of a display and an operator by receiving a reflected wave from the operator by an ultrasonic sensor, and adjusting brightness of back light according to this distance. CONSTITUTION:An ultrasonic wave emitted from an ultrasonic wave emitting device is reflected by an operator, and reaches an ultrasonic sensor 4. A CPU3 calculates a distance between the operator and a liquid crystal display 1 from information of the ultrasonic sensor 4, and adjusts brightness of back light 2 according to this distance. For example, when the operator approaches his face to the liquid crystal display 1, the brightness of the back light 2 is reduced, and when the operator leaves a little from the liquid crystal display 1, the brightness of the back light 2 is increased. When the CPU3 detects that a distance from the operator is not less than a prescribed value (about 1m), it judges that the operator leaves a seat, and stops an electric power supply to the liquid crystal display 1. Thereby display can be performed always in an easy-to-see form, and electric power consumption can be also reduced.

Title: Developing device
Inventor: DEGUCHI HIROYUKI
IPC: G03G15/08
Filed: 1986-05-30
Abstract: PURPOSE:To exactly and quickly detect the quantity of the density of a developer by attaching a developer detector to a prescribed position of the wall surface being adjacent to a stirring member, and attaching the stirring member to only a part excepting roughly a part opposed exactly to the developer detector. CONSTITUTION:A developer which has been scraped down by a tuft cutting member 11 is led toward the first stirring member 5 by a partition plate 12, stirred again, and also, a toner density in a stirring state is detected by a toner density sensor, 7 and when the toner density is an allowable density, a developing operation is executed as it is. While a toner density detecting operation is being executed, the first stirring member 5 is driven to rotate, but a part opposed exactly to the detecting surface of the toner density sensor 7 does not work a centrifugal force to the developer in this part, since the stirring member is omitted. In this way, a state that the developer is put against the detecting surface by following a rotation of the first stirring member 5 is always held in a prescribed state, and the toner density can be detected stably.

When an upper-limit change-over switch 17 is switched to an operation position B and a switch 19 is pushed, a lifting signal having a strength to prevent the return of the valve V to the neutral state even by the transmission of a feed back signal is transmitted to the control device 10 in place of a target level signal transmitted from a tilling depth setting device 15. The valve V is surely reset by again pushing the switch 19.
