Title: Axial tension sensor
Inventor: HATAMURA YOTARO
IPC: G01L5/16
Filed: 1984-08-04
Abstract: PURPOSE:To detect larger force without increasing a size of a parallel flat plate structure part by providing >=3 parallel deflection beams contiguously to a rigid body applied with force at right angles to the operation direction of the force. CONSTITUTION:Through holes 10a-10d are rectangular and formed vertically along a block 2 and they have the sample length and width and arrayed at equal intervals. Further, thin flat plates 11a-11e are formed by forming the through holes 10a-10d and are in mutually parallel relation. Then, the parallel flat plate structure 12 consists of parts centered on the flat plates 11a-11e. Strain gauges 8a-8d are installed at root parts of the flat plates 11a-11e. Then when vertical force is applied to a movable part 5, the structure 12 deforms. Namely, a distribution of stress converges on the root parts of the flat plates 11a-11e, so the structure 12 does not lose its features. Stress due to the deformation is distrisuted to the flat plates 11a-11e, so the quantity delta of displacement to the same force is small. Thus, large force is detected without any variation in size.

Title: Polling communication method
Inventor: RI SHIYOUYOU
IPC: H04L12/28
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To reduce a polling wait time by placing priority depending on kinds of each slave and data and causing contention through different delay times. SOLUTION: In the case of sending data from a slave 60 to a master 50, the master 50 sends a data packet C including information to inform start of contention to the slave 60. The slave 60 having data to be sent to the master 50 monitors its own reception port while awaiting a transmission opportunity for a prescribed delay time depending on the priority generated in itself at random. Then only a slave having no data to receive its own reception port generates at random its own preamble data D for the delay time generated in itself at random and sends the data to the master 50 and the master 50 sends the same preamble data E. The slave 60 compares the received preamble data E with the preamble data D sent by itself and sends a data packet F going to be sent when they are identical to each other.

IPC: G06F13/00
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To remove an adverse effect generated when the delivery of shared working environment information is automated and to automatically process the effective matching operation of a shared working environment. SOLUTION: Information for adding/updating a shared working environment is delivered from a delivery device 401 to a plurality of receivers 402, 403 through a network device 407 and an erasing instruction is executed. At the time of detecting a change in the working environment, the device 401 judges the changed contents, prepares environment information to be delivered, temporarily stores the prepared information in a memory, and after checking its function and a network, delivers the environment information stored in the memory to the remote receivers 402, 403.  At the time of receiving the environment information, each of the receivers 402, 403 temporarily stores the information in a memory, and after checking the function and the non-using and inhibition non-setting states of the information, defines the environment information stored in the memory as a regular environment information. Consequently, the environment can be automatically matched at real time while excluding illegal operation or the like generated due to automation.
