Title: Developing device
Inventor: HOSOI ATSUSHI
IPC: G03G15/09
Filed: 1985-12-10
Abstract: PURPOSE:To prevent a developer from being scattered and to obtain excellent copy images by providing a developer scatter preventing member which applies a voltage having the same polarity as the electrostatic charging polarity of a nonmagnetic developer to a container opening part opposite an electrostatic latent image holder. CONSTITUTION:The toner 8 in a toner storage container is sent to a developing container 11 through the rotary driving of a toner conveyance member 10. At this time, the conveyed toner is stacked in a mountain shape nearby the toner storage container opening and the skirt part of the mountain-shaped toner is collapsed by a toner supply member 9 to supply toner to a magnetic particle layer. The toner conveying member 10 differ in optimum value according to the consumption of toner, but preferably has conveying force so that the conveying speed is an about 1-5rpm low speed and the mountain of toner is maintained at the corridor part of the toner storage container opening part at any time. Toner scattered from a development part, on the other hand, moves in the rotating direction of a photosensitive body to make the instruments in a copying machine below a developing device dirt, so the developer is prevented from being scattered by rectifying the developing bias and applying the voltage having the same polarity with the toner to the scatter preventing electrode plate 15. Consequently, extremely stable image formation is possible.

Title: Control device for elevator
Inventor: KANEKO HIRONORI
IPC: B66B3/00
Filed: 1993-11-08
Abstract: PURPOSE:To make no registration process and efficiently operate an elevator when an instantaneous power stoppage or the like occurs and an erroneous input signal is received from a call input device by nullifying call registration when a prescribed number or above of call input signals are concurrently operated. CONSTITUTION:When hall call buttons S1-S8 are pushed, a hall call input device H transmits the hall call data of the relevant floors to a microcomputer M and turns on the corresponding response lamps L1-L8. The hall call input device H outputs a high potential when no hall call button is pushed and outputs a low potential when a hall call button is pushed. When an instantaneous power stoppage or the like occurs, the output data become a low potential, the microcomputer M might judge that hall calls of all floors are inputted and make the hall call registration process. To resolve this trouble, the call registration process in the microcomputer M is nullified when the input signals from the call input device H exceed the prescribed number of calls.

Title: Inverter driving device
Inventor: OGAWA MASANORI
IPC: H02M7/48
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent the useless current protecting operations of an inverter device by making the current detecting time constant of an overcurrent detecting circuit for an upper-arm transistor larger than that of an overcurrent detecting circuit for a lower-arm transistor. SOLUTION: A transistor 1 which drives a motor, etc., is provided with a sense current element to which a sense current which is proportional to a main current flows and makes an electric current to flow to a current sensing resistor 2. A drive circuit 3 drives the transistor 1. When the electric current flowing to the transistor 1 is not an overcurrent, signals from an input terminal drive the transistor 1 in a PWM state as they are through the drive circuit 3. When the current flowing to the transistor 1 becomes an overcurrent, however, the voltage detected by the sense resistor 2 rises and the transmission of the signals from the input terminal to the drive circuit 3 is stopped. When an overcurrent occurs, therefore, the output transistor 1 is disconnected so that the transistor 1 can be protected.
