Title: Liquid crystal display element
Inventor: YAMAMOTO TOMIAKI
IPC: G02F1/139
Filed: 1988-07-08
Abstract: PURPOSE:To obtain inexpensively a liquid crystal display element having noncolored light background and a wide view field angle by disposing two optical delay plates between a second substrate and a second polarizing plate and specifying a sum or retardations of the two optical delay plates with respect to the retardation of a liquid crystal cell. CONSTITUTION:Two optical delay plates 10, 11 are disposed between a second substrate 1' and a second polarizing plate 4, and a sum of retardations of the two optical delay plates 10, 11 is regulated to R0X0.8 to R0X1.2 with respect to a retardation R0=DELTAn.d.cos<2>theta for the liquid crystal cell 5, wherein d is a distance between the first substrate 1 and the second substrate 1', theta is a tilt angle of the liquid crystal compsn., and DELTAn is the birefringence rate of the liquid crystal compsn. If the value of the sum is less than a value in the above regulated range, a difference between the spectral transmission factors for a voltage impressed stage and voltage unimpressed stage becomes too small. If the sum exceeds said range, the spectral transmission factor becomes large for only a specified wavelength. Thus, a liquid crystal display element having a noncolored light background and a wide view field angle is obtd. inexpensively.

Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a nozzle body of a vacuum cleaner which can efficiently suck dust even though its arrangement includes a drive means for driving and rotating a rotating element. SOLUTION: A rotary cleaning element 130 is journaled within the suction chamber 31 of a case body 24. The output shaft of the electric motor of a drive means 147 is approximately coaxially engaged with a pulley 133 at one end of the rotary cleaning element via an output pulley 145 and the drive means 147 is disposed on one side of the case body. Cleaning elements 43 each comprising a brush body 42 and forwardly pointed bristles set therein are provided on the front and rear parts of the lower surface of one side of the case body 24 on which the drive means 147 is situated. The efficiency of sucking dust can be enhanced by scraping dust even on the lower surface of the one side through which a suction opening 30 is not opened and on which the drive means 147 is located at a greater distance from the suction opening 30.  The space between the brush body 42 and the cleaning element 43 serves as an air passage, enabling negative pressure to be increased on the lower surface of the one side on which the drive means 147 is situated, and thus enhancing the efficiency of sucking dust.
