Title: Buffer control method for electronic mail system
Inventor: TAKAI TOKIO
IPC: G06F13/00
Filed: 1990-03-20
Abstract: PURPOSE:To improve the processing efficiency and to resolve the complication of processing and management of chain information by storing data related to an application layer in a physically continuous transmission/reception buffer in the descending order (from the highest address toward the lower address). CONSTITUTION:At the time of transmission and reception of PDU (protocol data unit) between respective layers of an electronic mall system, PDU of UASL (user agent sublayer) and MTSL (message transfer sublayer) is stored in a transmission data storage buffer and a reception data storage buffer on a main storage device in the descending order (from the highest address toward the lower address). Therefore, it is sufficient if only the start address of PDU to be transferred is reported to PM (protocol machine) of the transfer destination layer at the time of transmission and only start and last addresses of PDU to be transferred are reported to this PM at the time of reception. Thus, it is unnecessary to physically move PDU between layers to improve the processing efficiency, and processing and management are facilitated because of the physically continuous buffer area.

Title: Light receiving device for coherent optical communication
Inventor: ONAKA HIROSHI
IPC: H04B10/61
Filed: 1989-03-20
Abstract: PURPOSE:To prevent a return light caused by the reflection on the surface of a light receiving device from reaching a local oscillation light source by interposing a 1/4 wavelength between each constant polarized wave coupler and a photoelectric element. CONSTITUTION:A 1/4 wavelength plate 4 is interposed between a radiation end of an optical fiber 14 and a photo diode 3. Thus, a linearly polarized light going from each optical fiber 14 passes through a 1/4 wavelength plate 4 where the light is converted into a circularly polarized light. Then the return light reflected in the surface of a light receiving device 15 passes again through the 1/4 wavelength plate 4 where the light is converted into a linearly polarized wave. The polarized wave face of the linearly polarized wave is intersected orthogonally with the polarized face of the original linearly polarized wave radiating from the optical fiber 14, and the return light is sent reversely in the optical fiber 14. Thus, the light passes through the constant polarized wave coupler 2 externally and the return light is not returned to the original light path.

Title: Degradation determination system for engine oil
Inventor: KOBAYASHI AKIHIRO
IPC: F01M11/10
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent a parametrical engine oil electrical resistance value from being influenced by temperature during measurement for a degradation determination of engine oil based on the change in concentration of oil undissolved parts. SOLUTION: A resistance value correction circuit 4 uses temperature-to- resistance characteristics of oil preset therein to correct measured electrical resistance values into those at specific base temperatures set for respective measurement. An arithmetic circuit 5 then obtains an initial resistance-value increment during the initial use of oil, and computes an undissolved-parts concentration corresponding to the initial use time from preset resistance-to- undissolved-parts-concentration characteristics. From the relationship between the initial use time and the corresponding undissolved-parts concentration, an estimation circuit 6 estimates a limit value of oil usable time corresponding to a preset allowable maximum value of undissolved-parts concentration.  As soon as the limit value is reached, a determination circuit 7 switches an alarm lamp 8 on to raise an alarm indicative of an oil degradation.
