Filed: 1998-12-30
Abstract: PURPOSE: A device for preventing a push of a semi automatic vehicle in an inclined road is provided to preventing a pushing when the vehicle is started after stopping in the inclined road. CONSTITUTION: A driver turns on a switch of brake stop light(16) by pushing a brake pedal during driving a vehicle and by checking if the switch of brake stop light(16) is turned on. A signal of angle sensor is received from a measuring sensor of inclined angle. And it is checked if the inclined angle corresponding to the inputted signal of angle sensor is over a previously set certain angle. When the appropriate inclined angle is over the certain angle, a ECU(electronic control unit)(60) is checks if the driver removes a foot from the brake pedal for starting the vehicle, that is the switch of brake stop light(16) is converted to be turned off. When the switch of brake light(16) is converted to be turned off, a clutch is partially connected by operating a solenoid valve(68). Therefore, the vehicle is started without pushing though the driver removes the foot form a brake.

Abstract: The present invention relates generally to broadband, reflective circular polarizers and, more particularly, to single layer super broadband, reflective circular polarizers. The polarizers of the present invention are made from a film of material, like a polymer having a cholesteric order, in which a second liquid crystal material, like a nematic liquid crystal, is distributed in a non-linear fashion across the thickness of the film in a plurality of liquid crystal-rich and liquid crystal-depleted sites in the polymer. The resulting polarizers have band passes approaching 2000 nm and reflect circularly polarized light which is either left-handed or right-handed depending on the final spiral structure of the materials utilized. The material of the present invention is fabricated by mixing commercially available polymers having a cholesteric order, a second liquid crystal material and a photoinitiator at a temperature which maintains the mixture in a liquid state. The polymer and the liquid crystal are present in a ratio by weight of 1:2, for example, and the photoinitiator is present in an amount of 0.6% by weight, for example, in the mixture. The heated mixture is then subjected to actinic radiation for a time and at an intensity sufficient to polymerize the polymer or the liquid crystal material or both. Under all polymerizing conditions the segregation rate of the liquid crystal material has to be greater than the polymerization rate of the material being polymerized. The liquid crystal segregates and diffuses, during polymerization, to sites of enlarged pitch in the polymer material from sites of shrunken pitch in the polymer material. Because the actinic light has an exponential intensity distribution due to light attenuation by, for example, light absorption, polymerization occurs in a non-linear fashion resulting in a non-linear distribution of the polymer and the liquid crystal material across the film.

Abstract: PURPOSE: A semiconductor memory device having a current address counter is provided to reduce the write test procedure and time by enabling to check write operation only with an input of continuous data after designating a first address. CONSTITUTION: In a module device of a DRAM having an EEPROM, a semiconductor memory device having a current address counter(20) performs the write operation of the whole chip by a continuous address signal being output through the current address counter. The current address counter(20) generates a series of continuous address signals by performing the counting with n bits in response to an input address signal during the current address write operation. Therefore, the device enables the sequential write only with data, without inputting the address by a clock synchronization, and therefore the number of clocks and the whole write time can be reduced. The circuit comprises a normal address counter(10) outputting a signal whose address is increased by +1 by m bit counting the input address signal and the current address counter(20).
