摘要:
A tear secretion quantity examination system for evaluating simply and non-invasively the tear secretion quantity has: a moisture evaporation quantity detection unit for detecting the moisture evaporation quantity from a subject's eye with a humidity sensor; and an operation unit for computing evaluation parameters of the tear secretion quantity based on a detection signal of the moisture evaporation quantity detection unit. The operation means approximates an attenuation portion of saw-tooth responses appearing for each blink in a tear evaporation profile in which the detection value obtained with the humidity sensor is plotted against the time.

The bridged metallocene compound or the olefin polymerization catalyst which comprises the compound, enables high polymerization activity in polymerizing one or more monomers selected from ethylene and α-olefins. The bridged metallocene compound contains specific substituted cyclopentadienyl and fluorenyl groups which are linked via carbon or silicon atoms. In the method for the preparation of polyolefins, one or more monomers, preferably ethylene as an essential monomer, selected from ethylene and α-olefins are copolymerized in the presence of the olefin polymerization catalyst comprising the bridged metallocene compound, so that an ethylene based polymer with an ethylene content of more than 50 mol % is obtained.

The voice-based manipulation method includes storing voice information for specifying manipulation targets in a storage section; manipulating the manipulation target which is associated with the voice information stored in the storage section; and searching the voice information stored in the storage section in association with the manipulation target.
摘要:
A switching system comprises a time division switch for forming a fixed path through which a line circuit and a trunk circuit are connected to each other. Both the line circuit and the trunk circuit have a discrimination function and a transfer function. For example, when the trunk circuit receives system data packets including predetermined system data packets from a call processor, the trunk circuit discriminates the predetermined system data packets from the system data packets using an identifier of each packet. The predetermined system data packets are transferred to the line circuit through the fixed path of the time division switch. Receiving the predetermined system data packets from the trunk circuit, the line circuit stores the predetermined system data as well as system data for the trunk circuit received from the call processor into a memory thereof. Using the predetermined system data and the system data for the trunk circuit stored in the memory, the line circuit processes communication information packets received from the terminal or the network.
