摘要:
A liquid crystal display panel (LCD) including a plurality of pixels. A plurality of drivers are provided and switched between a driving state and a non-driving state in response to an ON/OFF signal that is fed. The plurality of drivers drive the plurality of pixels of the liquid crystal display panel on the basis of a display data signal and a synchronizing signal, including a vertical synchronizing signal VSYNC, so that an image responsive to the display data signal is shown on the liquid crystal display panel. A signal generating section is provided to generate, on the basis of the vertical synchronizing signal VSYNC and the ON/OFF signal that is fed, a new ON/OFF signal synchronized with the vertical synchronizing signal VSYNC, and feeds the new ON/OFF signal into the drivers.

That is, a reflector for lighting includes: a reflective material made of a polymer membrane of which an average reflectance of 400 to 700 nm wavelength of at least one surface side is 85% or more and having a ridge-shaped uneven shape; and a reinforcing material having flexibility, and the reinforcing material connects the bottom parts of concave parts with each other from the back side of the one surface side of the reflective material to reinforce the uneven shape.
摘要:
A circuit board is connected to a connector including a connection port and contact portions located at upper and lower positions of the connection port. The contact portions face each other in the vertical direction, and each contact portion is connected electrically to the opposite contact portion. The circuit board includes a base substrate, a first wiring layer, and a second wiring layer. First terminals connected to the first wiring layer are provided on one principal surface of the base substrate, and second terminals connected to the second wiring layer are provided on the other principal surface. The first terminals and the second terminals come into contact with the contact portions and are arranged so as not to overlap each other in the vertical direction.
摘要:
An apparatus for estimating the origin time, the hypocentral distance, and the scale from time-series measured data of the electric field intensity which is observed accompanying a seismic ground motion, comprising a measuring means 21, 22 for measuring the electric field intensity, a data storing means 24, 25 for collecting and storing measured data from the measuring means, and a data analyzing means 26 for analyzing measured data stored in the storing means to detect origin time from the starting time of electric field increase, and to predict the hypocentral distance and the magnitude from the elapsed time from said origin time and said measured data, is provided.
摘要:
A casing pipe is inserted into a drilled hole reaching the inside of a confined aquifer in which groundwater is stored and flows or a position near the confined aquifer. A measuring device measures an electromagnetic field at the distal end of the casing pipe. An analyzing device analyzes data concerning the electromagnetic field measured by the measuring device to sense motion of ground pore water, thereby predicting rapid motion in the earth's crust, such as a volcanic eruption, an earthquake, a landslide and ground collapse. The casing pipe is an electrically conductive pipe having a non-magnetic screen portion formed at the distal end thereof so that recycling groundwater passes through the screen portion. The measuring device includes an electromagnetic field sensor placed in the screen portion and the conductive casing pipe as an electrode for measuring an electric potential relative to an electric potential at the earth's surface detected with a reference electrode.
