Title: Detecting device board thin
Inventor: UNNO SHIGENOBU
IPC: H01L21/68
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To accurately discriminate whether a slot is charged with a board or not by respectively forming a light projector and a light receiver of an light sensor with a light path obliquely crossing a surface of the board which is normally charged, at symmetrical positrons in relation surface of the board so as to detect the arrangement of the board. SOLUTION: In the case where boards 1 are charged in a fifth slot and a sixth slot at a different stage from each other, each output signal S1 and S2 of light sensors 4, 5 to each slot 3 are different from each other in the fifth slot and the sixth slot. A comparing and discriminating circuit 14 discriminates whether a difference between the signal S1, S2 exists within a set value of a tolerance setting circuit 15 or not in the fifth slot and the sixth slot. In the case where the difference between the signal S1, S2 exceeds the tolerance set value, inappropriate charge of the board 1 is discriminated.

Title: Timing regenerating circuit
Inventor: NAKAMURA MICHIHARU
IPC: H04L7/02
Filed: 1991-08-09
Abstract: PURPOSE:To predict and correct the phase deviation between a receiving signal and regenerating clock that occur when signal receiving is in stop, to reduce the phase deviation of regenerating clock for starting the intermittent receiving to shorten lead-in time. CONSTITUTION:Phase comparator 11, filter section 12, and regenerating clock means 13 are used to constitute a phase synchronizing loop to generate a regenerating clock that is synchronous with a receiving signal in terms of phase. Further, an error predicting means 14 monitors the output signal of filter section 12 that is in intermittent receiving operation, and predicts a phase error between the receiving signal and regenerating clock that occur when signal receiving is in stop on the basis of the monitoring result. Next, an error correcting means 15 corrects the phase of the regenerating clock generated by a regenerating clock generating means 13 when signal receiving is in stop or prior to the next intermittent receiving action so that the phase error predicted by an error predicting disappears in the next intermittent receiving action. since a phase error is reduced when the intermittent receiving action is executed, the lead in time is shortened.

Title: Degenerate action system of plural processor systems
Inventor: KAKIMOTO MASANORI
IPC: G06F15/16
Filed: 1984-10-26
Abstract: PURPOSE:To keep falsely a geometrical linking condition and to minimize the reduction of the whole peformance by changing over a communication bus fat and acting for the processing with a load share by an adjoining processor even when the processor partially breaks down. CONSTITUTION:When the processor (a) breaks down, a bus changeover signal (g) is outputted from a placed trouble detecting circuit (f). Next, due to the signal (g) set to a low level by an inverting terminal of a transmitter (m), a data transceiver (e) becomes invalid, a usual bus (d) is separated, and while the signal (g) is a high level, a data transceiver (j) becomes valid. Thus, processors (b) and (c) are linked by a trouble relaying bus (k). Next, the signal (g) is inputted to the processor (b) and the processor (b) executed the data processing in place of the processor (a). Thus, even when the processor (a) breaks down, by changing over the bus, the adjoining processor acts for the troubled processor, therefore, the whole performance reduction can be minimized.
