Title: Method for analyzing three-dimensional structure of foamed body of synthetic resin
Inventor: WASHIMI YASUHIRO
IPC: G01B21/32
Filed: 1992-02-14
Abstract: PURPOSE:To accurately analyze the dynamic characteristic of the foamed body of a synthetic resin when the foamed body is deformed by impact under an actual condition by applying a honeycomb construction pair model to the finite element method as a structure provided with an isotropic dynamic characteristic. CONSTITUTION:At the time of making arithmetic operation on the normal stresses of a core material model composed of the foamed body of a synthetic resin at every three-dimensional component based on each volumetric strain corresponding to the stresses, the same maximum stress curve found by static compression stored in a dynamic characteristic data memory 4a is used in accordance with the kind and expansion ratio of the synthetic resin. Therefore, the dynamic characteristic of a honeycomb model expressed by a metallic honeycomb structure model program 3b can be handled as the same characteristic, namely, an isotropic dynamic characteristic against all three-dimensional directions. As a result, the actual behavior of a core material composed of the foamed body of a synthetic resin having an isotropic dynamic characteristic can be expressed and accurate analysis can be performed.

Title: Data transmission controlling system
Inventor: ISHIMATSU HIDEAKI
Filed: 1985-02-15
Abstract: PURPOSE:To reduce a collision of a signal, and to raise the transmission efficiency by resetting a value of a clock adder, when a signal is detected, and executing a data transmission, only when the value of the clock adder is equal to a value of an intrinsic number setting part. CONSTITUTION:A clock adder 6 adds a value by one each at every two times of the maximum propagation delay time of a transmission line 8, and resets the value, when it becomes a larger number than the number of signal transmission devices connected to the transmission line 8. Only in case when a receiving part 3 has detected a signal through a signal detecting part 9, a signal is sent to a transmission and reception control part 4. When the signal is received, the transmission and reception control part 4 resets the value of the clock adder 6, and checks again whether the signal exists on the transmission line 8 or not. Said operation is repeated until it becomes impossible to detect the signal on the transmission line 8, and when it becomes impossible to detect the signal, the transmission and reception control part 4 reads out and compares values of the clock adder 6 and an intrinsic number setting part 7. When the values are equal, the transmission and reception control part 4 makes a transmitting part 2 start a data transmission to the transmission line 8 through a signal detecting and sending-out part 9.

Abstract: PURPOSE:To selectively and variably extract a light signal with optional wavelength from a light signal and vary the wavelength fast by using chiral smectic liquid crystal. CONSTITUTION:This filter is constituted by sandwiching chiral smectic A liquid crystal 17 which is close to a temperature of transition to a smectic C phase by using an orientation film 16 for liquid crystal, a mirror 15, a transparent electrode 14, and a glass substrate 12; and only optional light is selected among light pulses having many wavelengths and the wavelength of the filter is varied fast.

For the parallel orientation, a reversed parallel rubbing processing is only performed similarly to the orientation of normal nematic liquid crystal and for the vertical orientation, a temperature gradient method is only employed. Consequently, the sweep speed of the wavelength of the liquid crystal variable wavelength filter can be made faster by three digits than before.
