Title: Instantaneous reactive power compensating device
Inventor: YAMAMOTO MANABU
IPC: H02J3/18
Filed: 1991-05-29
Abstract: PURPOSE:To obtain an instantaneous reactive power compensating device capable of removing an unnecessary ripple current due to the swiching of a power converter when a compensating current value is small. CONSTITUTION:Reactive power and a higher harmonic current out of a load current are computed by an instantaneous current computing element and a compensating current for canceling the reactive power and the higher harmonic current are found out. The obtained compensating current value is compared with a certain reference value by an output controller 15, and when the compensating current is small, a voltage command from the controller 15 is outputted to a power conversion controller 14 to control the power converter 3 so as to stop it. When the compensating current is small and compensation is unneccessary, the flowing of an unnecesary ripple current due to the swiching of the power converter 3 into a system line can be suppressed.

Title: Working shape command device
Inventor: OBA SHUSUKE
IPC: G05B19/4093
Filed: 1989-05-22
Abstract: PURPOSE:To eliminate the execution of a rounding error correction command in a non-correction range by providing a non-correction range holding part in which the previously set non-correction range is stored, and comparison means. CONSTITUTION:A correction range holding part 7 holds a correction range instructed by a correction range command 12 as the range of a working locus which executes a rounding error correction, and the non-correction range holding part 1 holds the non-correction part which is set as the range of the working locus, which does not execute the rounding error correction of working shape data. The comparison means 2 compares the correction range with the non- correction range. When there is no coincident part, a correction allowable signal 14 is outputted. When at least a part of it is coincident, a correction range unjust signal 15 is outputted. When the correction range unjust signal 15 is outputted, CRT of a keyboard with CRT 4 displays the effect that the instructed correction range is unsuitable for executing the rounding error correction. Thus, working shape data can be corrected by avoiding the range of the working locus, in which the correction of a rounding error is prohibited.

Abstract: PURPOSE:To aim at making improvements in productivity and dimensional accuracy by setting up plural guide pipes having through holes up and down each at cutting intervals in alignment, inserting a long pipe thereinto, and drilling and cutting it from the upside of the guide pipe via these through holes and each interval. CONSTITUTION:Plural guide pipes 22 are aligned in line at cutting intervals, and through holes 22a and 23a are formed up and down each. When a long size plastic pipe 12 is inserted into these guide pipes 22, a hollow drill bit 28 and a rodlike electric heater 32, passing through this hollow grill bit, both are pressed down whereby the long pipe 12 is drilled via these through holes 22a and 23a, and the electric heater 32 is further depressed, thus chips come down. And, the drill bit 28 and the heater both go up while a cutter is displaced and thereby the long pipe 12 is cut off by this cutter from a clearance between these guide pipes 22. Consequently, since the long pipe 12 is drilled and cut in a state of being guided by there guide pipes 22, drilling and cutting for plural short pipes can be done in a highly accurate manner, this productivity is also improved.

Filed: 1991-05-30
Abstract: PURPOSE:To improve safety by setting an authentification key in a mobile equipment and a home memory station beforehand and providing an equal ciphered algorithm executing function. CONSTITUTION:A mobile equipment 1 and a home memory station 2 are respectively set an authentification key 3 and respectively equipped with an equal ciphered algorithm executing function 4, and an authentification request number containing a random number generated by a random number generation part 5 is transmitted from the memory station 2 to mobile equipment 1. Based on this received random number and the authentification key 3, the mobile equipment 1 executes cipher algorithm by the function 4 and transmits an authentification response signal containing the executed result to the memory station 2. A comparison part 6 compares this executed result with the certification key 3 of the memory station 2 and the executed result through the executing function 4 and judges either coincidence or non-coincidence. Therefore, since it is not necessary to hold the secret of the ciphered algorithm and further it is not necessary to execute transmission/reception while directly inserting the secret key to the signal, the safety is improved.
