Title: Three-axis measuring method of columnar test piece
Inventor: YOSHIKAWA HIROMICHI
IPC: G01N3/08
Filed: 1984-06-22
Abstract: PURPOSE:To easily measure the strain of a columnar test piece in three axial directions by fitting an annular arresting body onto the cylindrical part of the test piece, fitting a strain gauge to the arresting body, and applying force in the direction of the column axis. CONSTITUTION:The annular arresting body 2 is fitted onto the flank cylinder part of the columnar test piece. The annular arresting body 2 is made of a material with a high elastic modulus and the strain gauge 3 is stuck on its surface. When a load 10 is placed in the axial direction of the test piece, the body 1 expands radially by the Poisson effect to generate reaction force P in the arresting body 2. The reaction force is expressed by P=r.t.epsilonS.ES. In this case, the annular arresting body has a radius (r), thickness (t), circumferential strain epsilonS, and elastic modulus ES. At this time, (r), (t), and ES are known, so the reaction force P, i.e. radial stress is found by measuring epsilonS. Consequently, the stress in the columnar test piece in three axial directions is measured speedily from the axially applied force and measured value of the strain gauge.

Title: Positioning counter device for coordinate position
Inventor: KAJIWARA YOSHIHIRO
IPC: H03K21/02
Filed: 1985-06-13
Abstract: PURPOSE:To reduce number of components and to attain miniaturization by providing the 1st counter counting a forward rotation pulse, the 2nd counter counting a reverse rotation pulse and a pulse multiplier circuit, operating the difference between counts of the 1st and 2nd counters and the outputting the result as present position information. CONSTITUTION:When a rotary encoder RE is driven forward, only a forward rotation pulse FW is outputted from a pulse multiplier circuit 1 and inputted to the 1st counter T1 among the 1st-3rd counters T1-T3 and a data set from a central processing unit CPU is decremented proportional to the rotation quantity of the rotary encoder RE. When the rotary encoder RE is driven reverse, only a reverse rotation pulse BW is inputted to the 2nd counter T2, where the pulse is processed similarly. The present position on the coordinate is obtained by reading the data of both the counters T1, T2 and calculating the difference. In this case, one package per each control axis can constitute an up-down counter by using an existing programmable timer integrated circuit 5 where plural programmable timers are incorporated so as to attain miniaturization because of the reduction in component number.

Abstract: PURPOSE:To easily extend and disuse external input/output terminals without cutting optical fibers by providing an optical fiber bending means, which converts a part of the waveguide mode of the light in a first optical fiber to the radiation mode, and an optical waveguide. CONSTITUTION:A part of the waveguide mode of the light in the first optical fiber 1 is converted to the radiation mode in a bending part 1a of the first optical fiber 1, and the light is leaked out of the core. An optical waveguide 3 is so arranged that the light is guided in the tangent direction at the contact point to the bending part 1a, and the light leaked out from the bending part 1a is efficiently coupled to the optical waveguide 3. since a matching oil 7 for refractive index matching is provided in the contacting part between the bending part 1a and the optical waveguide 3, the leaked-out light is made incident on the optical waveguide 3 without being reflected. The incident light is propagated in the optical waveguide 3 and is emitted from an exit end 3a at a certain spread angle. Since an end part 2a of a second optical fiber 2 is directly connected to the exit end 3a, the light emitted from the exit end 3a is coupled to the second optical fiber 2, and thus, the light is efficiently coupled.

Abstract: PURPOSE:To realize a high system performance proportional to the number of processors by informing the number of the processor in a transmission destination to the processor having a communication request by a host computer and thereafter, processing the communication request from other part. CONSTITUTION:The processor P11 transmits the communication request to the host computer 1. A computer 1 detects the communication request, and when it is decided to be the request from the processor P11, the processor P23 of the transmission destination is decided. Then, the communication path between the computer 1 and the processor P11 is constituted to transmit the decided processor number. The processor P11 packets this number and transfer data and transmits this packet to the processor P12. The processor P12, when the number in the packet does not coincide with the number of its own, transmits the packet through the processor P13. Thereafter, this operation is repeated until the packet arrives at the processor P23. During this time, since the computer 1 is not participated in the transfer of the data, the communication request from other processor can be received, a parallel operation can be performed.
