Patent JP-H01161629-A (JP)
Title: Gold-plated contact
Inventor: KOTAKI FUMIHIRO
IPC: H01H1/023
Filed: 1987-12-18
Abstract: PURPOSE:To stably hold the contact resistance in the corrosion atmosphere by precipitating thallium on gold plating. CONSTITUTION:Thallium 100ppm or more is added to a gold plating liquid, and thallium 0.15% or more is precipitated. When the precipitation characteristic of thallium is as low as 0.01%, it has no effect on the contact resistance. The precipitated thallium may be 0.15% or more, but when it is excessive, oxidation of thallium occurs on the surface of gold plating, and it has no effect on the contact resistance. The contact resistance in the corrosion atmosphere, particularly in the SO2-NO2-NH3 mixed gas atmosphere, can be thereby held remarkably stably.

IPC: G06F9/46
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To improve the throughput of the whole system by efficantle allocating a CPU to a task of low priority even when a task of high priority continuously occupies the CPU. SOLUTION: Initial priority, timer initial values and time-out priority are registered in respective task control blocks 130a to 130c as parameters. The time-out priority is higher priority than the initial priority. A timer value control means 103 counts down a timer value, and when the time is up, the priority of tasks is changed from initial priority to the time-out priority. A task scheduling means 102 sorts executable queues 141 in accordance with the changed priority and a task control means 101 switches a task to be executed in the sorting order.

Title: Apparatus for detecting and discharging binding inferior saddle stitching book
Inventor: OTAKI SUSUMU
IPC: B07C5/36
Filed: 1988-12-20
Abstract: PURPOSE:To detect a binding inferior saddle stitching book to discharge the same by providing a binding inferiority detection circuit for detecting the binding inferior saddle stitching book on the basis of the signals from both of a saddle stitching book detection sensor and a metal detection sensor and operating a rejection device corresponding to the inferiority signal of said detection circuit. CONSTITUTION:A saddle stitching book 2B after bound by a binding wire passes the position of a saddle stitching book detection sensor 11 and that of a metal detection sensor 12. At this time, the saddle stitching book detection sensor 11 outputs a signal showing the presence of the saddle stitching book 2B continuously during passage while the metal detection sensor 12 outputs a wire detection signal at each time when the wire passes. Whereupon, the binding inferiority detection circuit built in an operating panel 9 counts the number of wire detection signals during the continuation of the signal showing the presence of the saddle binding book 2B from the saddle binding book detection sensor 11 to compare the count value with a set numerical value and, when both values are different, said detection circuit judges that the number of wires binding a predetermined position are inferior to output a binding inferiority signal. A control apparatus receives this signal to operate a rejection device 6 when the saddle stitching book 2B reaches said device 6 and discharges the same to the outside of a fed route.

Title: Circuit for fixing signal in reference value
Inventor: DABUIDO SHIEZUNOO
IPC: H04N5/18
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To fix an analog signal to a reference value and to reduce the sensitivity to noise by receiving a reference digital value and continuous values as the output of an A/D converter by a digital comparator and controlling the charging/discharging current of a capacitor dependently upon whether these continuous values are in a prescribed stable or divergent state. SOLUTION: After a signal Vc is amplified by an amplifier 10m an A/D converter 12 performs A/D conversion to output an output N, and the output N is inputted to an input A of a digital comparator 14' and a reference digital value Nref is inputted to an input B of this comparator. A control circuit 16 analyzes continuous values of output A>=B or A=B of the comparator 14' to detect the stable or divergent state and uses A=B+1 and A=B+1 for correction. The circuit 16 outputs UP and DN signals in accordance with these results to precisely control charging and discharging current sources Ic and Id of a capacitor C. Thus, the signal Vc is fixed to a reference value to reduce the sensitivity to noise, and further, oscillation due to the reaction time of the converter 12 is prevented.

Title: Evaluation method for software processing capacity
Inventor: SAITO HIROYUKI
IPC: G06F11/22
Filed: 1989-12-12
Abstract: PURPOSE:To improve the reliability of an evaluation test by giving an interruption from an interruption generation circuit to a processor while a pseudo load input is given at the time of a test. CONSTITUTION:At the time of the evaluation test, the pseudo load input is given from a pseudo device to the processor (CPU) 51 and the interruption is given from the interruption generation circuit 52 periodically or at random. Since CPU 51 interrupts a processing for the pseudo load input periodically or non-periodically and it has to execute the interruption processing, the load of CPU 51 increases, the processing capacity of software is relatively deteriorated, the generation intervals of the pseudo load input apparently become short, and environment similar to the increased load of software can be realized. Even if a personal computer whose processing speed is slow is used as the pseudo device, test environment equivalent to real environment for an overload test can be realized while the processing capacity of software can be evaluated. Thus, the reliability of the evaluation test improves.
