IPC: G02F1/13
Filed: 1995-03-02
Abstract: PURPOSE: To prepare a liq. crystal compsn. for an active matrix liq. crystal display device, which has a reduced threshold drive voltage while maintaining a high percentage voltage retention by incorporating two particular liquid crystalline materials. CONSTITUTION: A compd. represented by the formula I (wherein R<1> represents a 1-10 C alkyl; X<1> represents F, CF3 , or OCF3 ; and L<0> and L<1> represent H or F) is used as a first component, and at least one compd. of the formula II (wherein R<2> represents a 1-10 C alkyl; Z<1> is a single bond or -CH2CH2-; X<2> represents F, CF3 , OCHF2 , OCF3 , OCF2 CHF2 , or OCF2 CHFCF3 ; and L<2> to L<5> represent H or F) is used as a second component. The mixing proportions of the first component and the second component are respectively 3 to 50% and 30 to 97% based on the total weight of the liq. compsn. The first component is a liq. crystalline material which has a large Δε value and high chemical stability and can reduce the threshold voltage while maintaining high voltage retention under service temp.  The second component is a compd. having positive anisotropy in dielectric constant and possesses excellent thermal stability and chemical stability.

Title: Load sensor of electrostatic capacity type electronic scale
Inventor: HARUYAMA TADAYUKI
IPC: G01G3/00
Filed: 1984-04-05
Abstract: PURPOSE:To obtain variation in electrostatic capacity between both electrode plates accurately by arranging a ball between an upper-state and an upper-stage Roberval mechanism. CONSTITUTION:The upper-state Roberval mechanism 11 and lower-stage Roberval mechanism 16 are associated operatively with each other by providing the ball 21 between a lower leaf spring 15 and an upper leaf spring 19. When an unbalanced load (a) is placed on an upper counter pan 23 at a breadthwise end part, the upper-stage Roberval mechanism 11 slants, but the unbalanced load is not applied to the lower-stage mechanism 16 because of the presence of the ball 21 and the lower-stage mechanism 15 is therefore held parallel without slanting, so the parallelism between the fixed electrode plate 22 and movable electrode plate 24 is maintained even in the unloaded load state, and consequently variation in the electrostatic capacity between both electrode plates 22 and 24 is obtained accurately all the time.

Title: Semiconductor light-emitting element and manufacture thereof
Inventor: IDEI YASUO
IPC: H01L21/208
Filed: 1987-03-25
Abstract: PURPOSE:To effect control properly for the realization of a stable low impurity concentration by a method wherein Si is used as an donor impurity, the reaction temperature and carrier gas flow are regulated to control the quantity of Si, the reaction of Si and NH3 is used to keep Si as an impurity at low concentration, and growth is accomplished in an argon gas atmosphere wherein the Si impurity level is lowered. CONSTITUTION:A GaP substrate, Ga, and polycrystalline GaP are separately set on a quartz board, and hydrogen gas is purged into a reaction tube. Temperature is caused to rise under the ambient pressure. The board is kept at 1000 deg.C for a prescribed period, whereby the polycrystalline GaP melts into the Ga solution and, owing to the reducing reaction of H2 gas, Si melts out of the quartz board into the Ga solution. The Ga solution is placed on the GaP substrate, after which temperatures is lowered to 950 deg.C, when an n-type GaP layer 11 (carrier concentration: 2X10<17>cm<-3> or lower) grows. The carrier H2 is replaced with a gas mixture Ar+NH3 and, after a prescribed period of time, the carrier gas is replaced with Ar. A process follows wherein the temperature is lowered to 900 deg.C, when an n<->-type GaP layer 12 (carrier concentration: approximately 1X10<16>cm<-3>) grows. Next, with the temperature kept at 900 deg.C, Zn is heated and vaporized, and the acceptor impurity is introduced into the main furnace. After a prescribed length of time, the temperature is allowed to lower to 750 deg.C, where a P-type GaP grown layer 13 materializes.

After that, the oxide-based coating film of 1-15mum mainly containing Cr2O3 is formed on the inside surface of the radiant tube by heating at >=500 deg.C. As a result, frequency in working for replacing the radiant tube is extremely reduced.

IPC: G11B7/12
Filed: 1978-06-09
Abstract: PURPOSE: To achieve the higher efficiency of a plurality of laser luminous fluxes from a semiconductor laser array by using an optical system composed of 3 lenses.  
     CONSTITUTION: Laser luminous fluxes out from the emission points 1a, 1b on a semiconductor laser array 1 are separated to two laser luminous fluxes 3a, 3b after passing through a coupling lens 2 of, e.g., 20 times, and 1a, 1b are magnified and imaged on an image plane P. A lens 5 having a suitable focal length is placed on this image plane P to let the images on the lens 2 be formed on a stopping-down lens 4. This results in that the luminous fluxes 3a, 3b overlap just on the lens 4, thus the vignetting of the lens 4 is completely eliminated and a micro-spot is formed on the final imaging plane (disc face) 7. The utilization efficiency of the laser luminous fluxes may be enhanced by such optical head for information processing.
