摘要:
A liquid crystal display device comprises an optically diffusively reflecting layer arranged to maximize utilization of incident light. The reflecting layer contains a thin metallic film with projections (14a) each having an unsymmetrical cross section to centralise reflected light in a specific azimuth direction (y). The range of viewing angles (θx-z, θy-z) into which a substantial portion of the incident light is reflected is broader in the specific azimuth direction (y) than in another direction (x). The director (5d) of liquid crystal molecules initiallly lies in a plane (y-z) parallel to the specific azimuth direction (y) to achieve retardation self-compensation.

A method for analysis of solvent evaporation patterns includes: continuously evacuating the gas of a single-component or multicomponent solvent evaporated under desired evaporation conditions from an object containing the single-component or multicomponent solvent housed in an airtight container, with evacuation means from the airtight container to an exhaust path connected to an exhaust port of the evacuation means; sampling a gas at predetermined time intervals from a desired point between the airtight container and the outlet of the exhaust path with the continuous evacuation maintained; measuring the solvent gas contained in the sampled gas; and determining an evaporation pattern of the solvent from the object under the desired evaporation conditions, from results of the measurement.
摘要:
A computer executes a monitoring control by receiving a first notification which has been transmitted from another communication apparatus to a network, and acquiring first identification information which is identification information of the communication apparatus at a predetermined first layer, from the first notification. The computer acquires second identification information which is identification information of the communication apparatus at a second layer being lower in hierarchy than the first layer. The computer associates the first identification information and the second identification information, and acquires a connection state between the network and the communication apparatus at the second layer.

摘要:
Overload protecting operation is performed by controlling the current peak value of a switching device 1 through the use of a comparator 8, a NAND circuit 5, and so on according to variations in feedback current being input to a feedback signal control circuit 11, internally setting the overcurrent protection of switching device 1 through the use of a clamp circuit 12, charging a capacitor 34 when having fallen below a specified current smaller than current required for the overcurrent protection for a fixed time period, and detecting rise in voltage VOL at the capacitor 34 to a constant voltage to stop switching operation.By achieving the overload protection under normal load and the overcurrent protection against peak load in a single switching power supply unit, problems such as the complexity of the unit and an increase in the element count of the control circuit are solved.
