Title: Rotor position detecting method for commutatorless motor
Inventor: FUKADA AKIYOSHI
IPC: H02P6/182
Filed: 1992-02-20
Abstract: PURPOSE:To make it possible to detect the position of rotor with no phase lag and to eliminate the influence of multiplex pulse by employing a comparator having no hysteresis characteristics. CONSTITUTION:Armature terminal voltages are passed through filter sections 2, 3 to produce three-phase AC signals which are then compared with zero voltage at comparator sections (CP) 10-12 having no hysteresis characteristics. For example, a multiplex pulse generated at the rising of output from a CPU 10 is employed in the detection of the edge of signal Al at an edge detecting section 15 and an interruption takes place at a processing section 18. Signal levels of CPUs 11, 12 are then determined. If signals B1, C1 from the CPUs 11, 12 have L and H levels, i.e., normal levels, respectively, a decision is made than the interruption is valid. Consequently, rotor position of a commutatorless motor(MT) is detected, and a driving signal and an inverted signal thereof for switching the armature current flow of the MT are outputted. If the outputs from the CPUs 11, 12 are abnormal, a decision is made than the interruption is invalid.

Title: Sequence controlling method
Inventor: KASAHARA IKUO
IPC: G05B19/05
Filed: 1980-05-29
Abstract: PURPOSE:To eliminate variations caused by a scan time, by setting a value which has been counted by an input time counter in advance, to an execution output time counter. CONSTITUTION:When time between incoming of an input signal and its output  from an operation part after executing the program concerned is referred to as t1,  the execution output timing is delayed by a scanning time t-t1 behind an output time point of the operation part. According to this method, as for the execution output timing, it becomes the same execution output timing as the fact that an interruption signal has been inputted at the time shifted by 1 scan portion. That is to say, the shift of the input timing of an input signal from a sensor is counted by a time counter 11, and a value which has been counted in this way is set to an execution output time counter 12 in advance. In this state, if an input signal comes in from the sensor, an output signal is always outputted to an apparatus to be controlled 13 from a sequence control device 20 after the lapse of a constant time.

Title: Packet video conference communication system
Inventor: INMAKI NAOFUMI
IPC: H04L12/801
Filed: 1990-03-20
Abstract: PURPOSE:To prevent the quality of pictures or sounds from degradation caused by increasing the delay between end-to-end by decreasing the amount of traffic to be sent from a self-terminal when the amount of traffic to be sent from the self-terminal is more than a fixed value and simultaneously the amount of traffic on LAN is more than a fixed value. CONSTITUTION:A traffic measuring means 11 always measures the amount of traffic sent from the self-terminal and the amount of traffic on the LAN and announces measured results to a traffic control means 12. The traffic control means 12 analyzes the results of measuring the traffic and when the amount of traffic sent from the self-terminal is more than the threshold value and the amount of traffic on the LAN is more than the threshold value, the means 12 judges it is necessary to decrease the amount of information to be sent from the self-terminal. Then, it is instructed to a picture codec part 7 and a sound codec part 8 to decrease the amount of information to be sent. The picture codec part 7 decreases the upper limit value of the information amount to be sent and the sound codec part 8 decreases the information amount of be sent. Thus, the quality of pictures and sounds can be prevented from degradation caused by increasing the delay between end-to-end.

Title: Method for measuring thickness of aluminum or aluminum alloy plate
Inventor: KURODA MASAYUKI
IPC: G01B15/02
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To reduce the error between the thickness of an aluminum or aluminum alloy plate calculated from the absorption coefficient found by roentgenization and the actually obtained thickness of the plate by calculating the thickness by using a corrected absorption coefficient found by giving consideration to the temperature correction value for thermal expansion. SOLUTION: The temperature correction value (r) which is a variation is found from the absorption coefficient (u) only thinking over the alloy component of an aluminum plate by taking the variations of the thickness and specific gravity of the plate caused by thermal expansion into consideration. Since the temperature correction value (r) can be expressed by a function which only relies upon the temperature, a corrected absorption coefficient W is found from a formula, W=u+r. Therefore, the actually obtained thickness (t) of the aluminum plate can be found by calculating such a thickness (t) that meets a formula, I=I0e-Wt (where, I and I0 respectively represent the outgoing and incoming intensities of X rays).  Thus the corrected absorption coefficient W can be obtained by taking the temperature correction value (r) into consideration in addition to the absorption coefficient (u) thinking over the alloy component.

Abstract: PURPOSE: To reduce the increase of back pressure within an exhaust passage caused by the installation of the supercharger by a constitution wherein the internal combustion engine with the supercharger is so constituted as not to be subjected to the back pressure by passing the exhaust gas through a bypass passage when the pressure within a suction passage becomes negative.  
     CONSTITUTION: At first the engine 1 with the supercharger is driven in the range in which the pressure within the suction passage 6 shows negative by adjusting the opening of a throttle valve 8. Under these operating condition, the suction passage pressure receiving chamber 174 in a valve driving means 17 is applied by the negative pressure in the suction passage 6 by means of the release action of a check valve 20 and the standard pressure receiving chamber 173 is applied by the positive pressure in a compressor 101. Due to the constitution described above, a exhaust gate valve 16 is actuated to be opened to let the exhaust gas pass through the bypass passage 15, goint a turbine 13 round. When the engine 1 with the supercharger is driven in the range in which the pressure within the suction passage 6 shows positive by shifting the opening of the throttle valve 8 to a larger opening position, the bypass passage 15 is closed.

Abstract: PURPOSE:To improve the measurement precision of a work position and a tool position and to perform the automatic measurement processing free from destruction of a tool or the like by detecting a stop position in a position detecting block executed with the skip signal from a detecting means. CONSTITUTION:A detecting means like a position detecting sensor is arranged in a movement route where the tool is moved, and the skip signal is inputted from the detecting means to an input circuit 8 when a work or the tool is brought into contact with this detecting means. Current limitation of the servo motor of a moving axis is commanded from an output circuit 5. At this time, a program command block is advanced to the next by the skip signal to command abortion of movement. Error data of each shaft stored in a servo control part as an extent of movement which is not executed out of the movement extent command value commanded from the output circuit 5 is subtracted from this movement extent command value to operate the stop position of the axis, which is actually stopped by current limitation, by the operation commanded by the next command block in a CPU 1. Thus, a numerical controller is obtained which improves the measurement precision and is free from destruction of the tool or the like.
