Title: Hinge mechanism
Inventor: SALTER TONY
IPC: E05D11/10
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain reliability from the viewpoint of the number of times of opening and closing operations and smooth movement with little resistance by constituting a mechanism by a hinge shaft having a cam surface and an elastic means adjusted so as to cooperate with the cam surface and loading an elastic device according to different directions of the cam surface due to relative rotation. SOLUTION: In a hinge mechanism, each of an elastic means and a cam surface rotates so as to change torque between the elastic means and the cam surface. When a first housing and a second housing are located at open locations, the first housing and the second housing are biased each other to open direction locations, and when the first and second housings are located at close locations, the first housing and the second housing are biased each other to close direction locations. Thus detent torque is generated in the housings at open locations and close locations. A plane opposed to the can surface is oblique to a vertical shaft of a hinge shaft 42 and thereby detent torque is generated.  The hinge shaft 42 is provided with a projection part 70, the projection part 70 is joined to a corresponding projection part of the second housing, and thereby a joint point of the projection part supports the first housing and the second housing at open locations.

Title: Paging system
Inventor: SUGINAGA SUSUMU
IPC: H04W4/00
Filed: 1987-06-12
Abstract: PURPOSE:To prevent a called pager call number from being resent out by a CPU and from be rung two times, at the time of switching an area controller, by forming a part between a control circuit and a storage circuit of the area controller by a duplex constitution by a cross call. CONSTITUTION:When a fault is generated in an existing '0' system area controller G while a called pager call number is being sent out to a transmitter I, an existing order is sent out to an input/output interface circuit 1' of a stand-by '1' system area controller H from a CPUE. Subsequently, the circuit 1' outputs a read request of the existing order to a control circuit 2', and the circuit 2' outputs a stop instruction through the other system control line 5 to a control circuit 2 of the controller G. Next, the controller H sends out the called pager call number continuously from a fault generation time point to the controller G through transmission counters of a storage circuit 3 and 3'. In this case, the circuit 2 and the circuit 3', and the circuit 2' and the circuit 3 are brought to a duplex constitution by a cross call 6, therefore, at the time of switching of the controllers G, H, it becomes unnecessary to resend out the called pager call number from the CPUE, and also, it can be prevented that the called pager is rung two times.

Filed: 1985-07-04
Abstract: PURPOSE:To detect toner residual by discriminating the reduction of toner in a toner feeding means for detecting the toner density of a two-component developer stored in a developing unit and feeding toner less the a prescribed volume when the number of times of feeding by the toner feeding means exceeds a reference value. CONSTITUTION:The developing unit 7 executes development by using the two- component developer consisting of toner and carrier and the developer is carried to a sliding part with a photosensitive body 2 by a magnetic roller 21. A magnetic sensor 23 is fitted to the side wall of the developing unit 7 so that its detecting head 24 is exposed into the developing unit 7. The detected toner density is supplied to a microcomputer through an A/D conversion circuit. The computer compares the toner density with a set-up reference level and drives a solenoid in accordance with the compared result to feed the constant quantity of toner to the developing unit 7. The number of times of toner feeding is calculated, and when the calculated value exceeds a reference value, the reduction of toner in a hopper 25 less than the prescribed volume is discriminated. Thus, the toner residual can be precisely detected.
