Title: Earthquake predicting method via optical fiber
Inventor: HORIMA HIROAKI
IPC: G01V1/00
Filed: 1978-10-27
Abstract: PURPOSE:To predict the earthquake by making use of the suddeh increment of the transmission loss of the optical fiber caused by the microbending. CONSTITUTION:A hole is drilled to the rocks R of the sands M at seashore S, and optical fiber core F, which features the refractive index error of under 1% and is liable to receive the microbending with no microbending preventing buffer layer coated, is inserted into the hole. Then thermosetting resin D is filled into the gap part of the hole. Thus when rocks R protrudes to show a premonitory symptom of the earthquake, core F has the microbending due to the side pressure to give a sudden increment of the propagation loss. In this connection, the optical power propagating fiber F via both ends A and B of fiber F is measured, and thus the earthquake can be predicted easily by checking the fluctuation of the optical power.

Title: Automatic original feeder
Inventor: HAYAKAWA KIMIAKI
IPC: G03G15/00
Filed: 1985-06-18
Abstract: PURPOSE:To deliver a stack of originals piece by piece in an accurate manner even to such one that is curled upward, by setting up a separation belt to be tilted with an angle of less than the specified one with a delivery belt. CONSTITUTION:Adding pressure of W due to a weight plate, stacked originals 21 are delivered to the left by a paper feed roller 22, and an original at a lowermost position is conveyed to the left by a delivery belt 25, while the original situated more upper than the original at the lowermost position works so as to be put back to a right upper part by a separation belt 28. Hereat, force F for restoring the original by the separation belt 28 works rather in a horizontal direction than to be a right angle with the separation belt 28 by frictional force between the separation belt and each original 22. Therefore, component force F1 keeping the original is small but another component force F2 for pushing back the original grows larger. That is to say, when a tilt angle theta' is in a range of more than 60 deg. and an original tip end comes into contact with a rectilinear running part 28a of the separation belt 28, these stacked originals are delivered piece by piece in an accurate manner.

Title: Frame synchronizing system for loop-type communication network
Inventor: TAKEUCHI TAKAO
IPC: H04L7/00
Filed: 1986-06-10
Abstract: PURPOSE:To prevent out-of-frame synchronization from occurring continuously and to shorten a time required for pull-in by always inserting the prescribed frame synchronizing pattern in a frame synchronizing bit in a loop at each communication node. CONSTITUTION:An exchange control circuit 13 at each node controls a switch 16 in the frame synchronizing bit position to insert the synchronizing pattern that a synchronizing pattern generator circuit 17 generates unconditionally. The circuit 17 generates the synchronizing pattern according to a frame phase at the node, and supplies it to the switch 16. Since the frame phase at the node is constant, the signal with the frame synchronizing bit in a fixed position without fail is transmitted regardless of the frame synchronization state in a frame synchronizing circuit 10, and out-of-frame synchronization never occurs unless otherwise the erroneous transmission happenes.

Title: Titer plate reader
Inventor: KIRIE SUZUKO
IPC: G01N21/03
Filed: 1993-05-11
Abstract: PURPOSE:To automatically and highly accurately measure many kinds of titer plates optically by identifying the number of wells of each titer plate before the optical measurement. CONSTITUTION:The light for optical measurement from a light source 1 is changed to a light of a specific wavelength by an interference filter 5 and separated to 8 by an optical fiber 2. The light vertical to a titer plate 3 passes through the wells, and the transmitting light is optically analyzed by a detecting part 4. Before the optical measurement for each well, a specific part of the titer plate 3 is optically measured, so that the number and form of the wells are analyzed from the difference of the optical properties. Simultaneously when the number of wells is recognized, a position proper for the optical measurement of tone well is calculated on the basis of the data. The optical measurement is conducted only at the position. Accordingly, it becomes possible to eliminate the optical incorrectness resulting from the measurement at an incorrect position and to achieve accurate analyses to measure the sample in the well optically.
