Title: Device for restricting operation of generator
Inventor: SEI SHINJI
IPC: H02P9/14
Filed: 1995-04-18
Abstract: PURPOSE: To restrict the leading and delaying reactive powers of a generator, by computing based on its effective power its reactive powers from its generator capacity curve. CONSTITUTION: The voltage of a voltage sensing portion 2 is compared in a comparing portion 4 with the set voltage value of a voltage setting portion 3 for their difference to be sent to a voltage compensating portion 5 as a voltage deviation. The effective power of an effective power sensing portion 6 is sent to an operation setting portion 8 to output delaying and leading reactive power set values (Qrs), (Qcs) opposed to the sensed effective power. A reactive power Q from a reactive power sensing portion 7 is compared with the Qcs in a comparing portion 9 for their difference to be sent to a leading-reactive-power compensating portion 11 as a leading reactive power deviation. Also, the reactive power Q is compared with the Qrs in a comparing portion 10 for their difference to be sent to a delaying-reactive-power compensating portion 12 as a delaying reactive power deviation.  In a high-value preferring portion 24, the output of the leading-reactive-power compensating portion 11 is compared with zero signal, and when it has a high value it is sent to an adding portion 27. In a low-value preferring portion 26, the output of the delaying-reactive-power compensating portion 12 is compared with zero signal, and when it has a low value it is sent to the adding portion 27.

Title: Sorter
Inventor: IWAMOTO MINORU
IPC: G03B27/00
Filed: 1981-06-19
Abstract: PURPOSE:To prevent occurrence of a sorter jam in a bin of reset motion, in an off-line type sorter, by inhibiting copy sheet counting motion and bin step motion for a prescribed time after resetting to normal from removal of jammed paper. CONSTITUTION:During operation of a sorter 2, if a copy from a copying machine main unit 1 is jammed at a side of the sorter 2, a signal S7 of a bin insetion completion sensor 23 is left as in H, and an H signal S16 by a time limit of a timer T3 turns on a jam display unit 8 through OR circuits O11, O8. If the jam is removed, the sensor signal S7 is changed to L, and the timer T3 is cleared, then a monomultivibrator M1 is triggered to change its output S8 to H. However, output of a timer T4 is held to L only for a period of pulse generation of this H outut and changed to H after the output S8 becomes L, thus misoperation, deriving from immediately setting a flip flop FF5, can be prevented. Accordingly, when the jam is removed, misoperations of a counter CNT and bin step mechanism are never be caused.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of weld lines on the post-stream side of a through-hole by forming a thick wall section on the periphery of the through- hole formed on a plate-shaped main body. SOLUTION: A round through-hole 2 is formed on a plate-shaped main body 1. A thick wall section 5 is formed on the peripheral edge of the main body 1 forming the periphery of the through-hole 2. At that time, the thick wall section 5 is formed into the section rectangular shape or the like. When the diameter of the through-hole 2 is set as R, the thickness of the main body 1 is set as (d), the width of the thick wall section 5 of the section rectangular shape is set as W and the thickness of the thick wall section 5 is as D, for instance, the formulas of D>=2d and W<=R/10 are applied. Then the resin flow direction branched on the section of the through-hole 2 at the time of injection molding is formed at random by the action of the thick wall section 5, and extreme joining action on the post-stream side of the through-hole 2 is not generated.  The generation of weld lines on the surface of the main body 1 on the post-stream side of the through-hole 2 at the time of injection molding can be prevented effectively by the arrangement.
