Title: Preparation of alpha-allyl substituted deltaepsilon-unsaturated aldehyde
Inventor: NAKAI TAKESHI
IPC: C07C45/51
Filed: 1979-08-28
Abstract: PURPOSE: To obtain the titled compound useful as an intermediate for a perfume or medicine readily, by rearranging an easily manufacturable allyl type ether under heating to suppress the retro-ene type decomposition and increase the reaction yield of the Cope rearrangement.  
     CONSTITUTION: An allyl type ether of formula II (R 1 WR 8  are H's or hydrocarbons, however, any two of them may form a ring with the carbon atom if the desired rearrangement is not affected) is rearranged under heating in an inert gas atmosphere, e.g. N 2  or He, and at 150W250°C in the liquid phase or at 300W400°C in the vapor phase to give the titled compound of formula I. The allyl type group in the compound of formula II shows the protecting action on the proton of the hydroxyl group and suppresses the retro-ene type decomposition reaction to become the allyl substituent at the α-position of the compound of formula I. The Cope and Claisen rearrangements are believed to occur continuously in the same reaction system.

Title: Liquid crystal display device
Inventor: HASHIZUME KYOICHI
IPC: G02F1/13357
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent generation of uneven brightness in a liquid crystal display panel caused by heat generation of a fluorescent tube in the case of having an edge back light. SOLUTION: A radiating sheet 22 is stored in a groove 21 formed on a surface of a resin case 1 in a pressure contact state to a inner surface of a shield case 2. Accordingly, heat conducted from a fluorescent tube 8 to a bottom part of the groove 21 of the resin case 1 is rapidly conducted through the radiating sheet 22 to the shield case 2 so as to be difficult to conduct to an end surface 4a of a liquid crystal display panel 4. Furthermore, because the tube center of the fluorescent tube 8 is disposed in an opposite side of the liquid crystal panel 4 on a basis of a central normal line 5b of an end surface 5a of a light guide plate 5 in its thickness direction, heat from the fluorescent tube 8 is more difficult to conduct to the liquid crystal display panel 4.  A reflective surface of a reflecting sheet 6 facing to the light guide plane 5 has a light- absorbing pattern corresponding to uneven brightness caused by heat generation of the fluorescent tube 8.

Title: Regulating device for exposure
Inventor: SUZUKI KAZUHIRO
IPC: G03G21/00
Filed: 1981-07-16
Abstract: PURPOSE:To obtain correct exposure on a photoreceptor with respect to a change in macro-magnifications over a wide range by combining the control of the quantity of the light emitted by an exposure lamp and the control of the quantity of the light by a slit. CONSTITUTION:A microfilm 2 is projected onto a photosensitive drum 5 by a projecting lens 3. If only the quantity of light of a lamp 1 is regulated to control the exposure in accordance with a change in macro-magnifications in this case, there is the possibility of an unstable change in the sensitivity of the photosensitive naterial on the emitted light. Thereupon, a magnification setting instructiob signal is applied from a setting means 10 to a microcomputer 9, then a control signal is emitted to a slit driving means 7 and the lamp, by which both of the slit width and the quantity of light of the lamp are changed. Since the wavelength of the light emitted by the lamp does not change largely, unstability with the sensitivity of the photosensitive material on the drum is reduced.

Title: Directional coupler device and electric power measuring method in it
Inventor: ARI SARUMINEN
IPC: H04B3/46
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To improve the measurement precision and reliability of this device on a low power level at the time of measuring a radio frequency power through directional couplers. SOLUTION: This device has directional couplers 1 and 2, a detector 4, a termination impedance 12 and a control circuit 11, and the impedance value of the impedance 12 is changed through a control signal.

Title: Method for judging proper function of car-carrying-type speed meter
Inventor: KATOU TETSUO
IPC: G01P21/02
Filed: 1981-07-17
Abstract: PURPOSE:To reduce measuring errors in a vehicle speed tester by comparing a displayed locked value of a speed meter with a predetermined value, so that the needle of the car-carrying speed meter falls upon a standard value. CONSTITUTION:A car 11 is placed on the vehicle speed tester 1 whose rear drum 3 is turned by a command device 10. Its revolution is then transmitted to a vehicle speed calculator 4 so that the vehicle speed of the car 11 is displayed on a digital speed meter 6-9 of a speed display device. When the car-carrying speed meter displays a predetermined value by controlling the accelerator pedal, whereupon a lock switch 12 is pressed, the vehicle speeds given by the calculator 4 are lock-displayed on the corresponding indicators 7-0. Proper function of the car-carrying speed meter is evaluated by judging if the difference between the locked display value and the value displayed on the car-carrying speed meter exists within a standard value.
