Filed: 1990-03-30
Abstract: PURPOSE:To control a motor correctly by a method wherein the pulse signal of an encoder is detected by the accelerating position of rotation having different ripples while the torque ripple, generating the angular speed of fluctuating rotation having reverse phase, is generated to add both torque ripples synergistically. CONSTITUTION:A frequency dividing signal is transmitted to a motor 11 through an amplifier 19 and the like to control the speed of the motor 11 but a comparing signal is transmitted to a reverse phase shifter 32 and the control signal of fluctuating rotation angular velocity omegai (two-dot chain line), reverse to another fluctuating rotation angular velocity omegao (one-dot chain line), is generated. This control signal is transmitted to the motor 11 through another amplifier 33. Accordingly, the motor 11 is added synergistically with a torque ripple, having the fluctuating rotation angular velocity omegao and another fluctuating rotation angular velocity omegai reverse to the angular velocity omegao, whereby the torque ripple is reduced and a straight line type torque T is obtained. According to this method, the motor 11 is rotated under a condition that the motor 11 has no fluctuating component.

Title: Video conference system
Inventor: NAGAO SEIJI
IPC: H04N7/15
Filed: 1993-04-12
Abstract: PURPOSE:To efficiently prepare reception by recognizing information such as paper exhaustion or conference participants of both of reception by previously transmitting the number of pages to the reception side in the case of returning documents such as conference materials. CONSTITUTION:An X side terminal performs transmission by controlling and informing (C and I) the number of pages in documents to be transmitted from now, and the responses of C and I from a Y side terminal are executed. When the response can be printed out, a normal document transfer sequence is started. Thus, the number of pages in the data of documents or the like to be transferred is previously communicated by the inform signal and when it can not be received, a message is displayed to a user. Therefore, since the number of pages in the data of documents such as conference materials can be previously transmitted to the reception side when transmitting the documents, the information such as paper exhaustion or conference participants of both of reception can be recognized. Accordingly, since the addition of printer paper or the like can be pressed to the user, the reception can be efficiently prepared.

Filed: 1995-04-10
Abstract: PURPOSE:To get a tensile member to share horizontal force by installing preliminarily a tensile member between support mother members in a stretching manner and installing an arched slab board between the support mother members. CONSTITUTION:Before an arched slab board 1' is installed, a tie bar 10 with a turnbuckle are preliminarily installed between bearing walls 9 and 9' in a stretching manner. Then, an arched slab board 1' is installed between the bearing walls 9 and 9'. Since a horizontal force, which acts on the bearing walls 9 and 9' by a vertical load, which is applied to the arched slab board 1' is shared by the tie bar 1 during the installation, substantially no force acts thereon. Then, the arched slab board 1 is installed between a beam 3 and the bearing wall 9' and slab floor concrete is placed on the top and the top of the previously installed arched slab board 1 so as to finish the slab board. Then, the tie bar 10 is removed after the slab board is finished. Since the horizontal force produced by the arched slab boards 1 and 1' acting on the bearing wall 9' cancel each other, no continuous horizontal force acts.
