Title: Projection type display device
Inventor: FUJIMORI MOTOYUKI
IPC: H04N5/64
Filed: 1994-12-27
Abstract: PURPOSE: To realize the projection type display device convenience in carrying provided with a structure of high impact resistance performance in which possibility of position deviation or damage or the like of each part is precluded even when the display device receives a shock due to falling off or the like. CONSTITUTION: An upper case 3 and a lower case 4 being components of an outer package case 2 of the projection type display device 1 are fixed to a power supply unit 7 and a head plate 903 with especially high stiffness to enhance the integration and stiffness of the entire case thereby improving the falling off resistance characteristic or the like. A prism unit 910 and a projection lens unit 6 of an optical lens unit 9 are fixed to the head plate 903 while being arranged in the optical axis direction. Since both the components are strongly fixed, the occurrence of position deviation or the like due to a shock at falling off or the like is less caused.  The power supply 7 and the projection lens unit 6 whose weight are heavy are arranged to the front and the rear side of the display device opposite to each other so that the gravity center of the display device is almost matched with the geometrical center of the display device and the power supply unit is fixed at a midposition of its height. Even when the display device is fallen off in mistake, the display device is fallen off without changing its posture, then a damage or the like is hardly caused. Moreover, lateral shake of the power supply unit is not caused.

Abstract: PURPOSE:To promote removal of a deleterious ingredient and improvement in combustion efficiency by decreasing an intake air quantity so as to make an air-fuel mixture at the neighborhood of an ignition means turn into high concentration as far as the neighborhood of rich limitation in a low load driving area, but increasing it so as to become the low concentration as far as the lean limitation in a medium load driving area, respectively. CONSTITUTION:At a low load driving area, a control unit 30 controls the opening of a throttle valve 8 so as to make air-fuel mixture concentration in the neighborhood of a spark plug 13 at the leading side turn into rich limitation in relation to an intake air quantity. Then, according to engine load, fuel is sprayed from only a fuel injection nozzle 12, igniting it by another spark plug 11. In consequence, exhaust ga temperature goes up so sufficiently, a catalyzer in an exhaust gas emission control device 21 is heated and thereby a deleterious ingredient in the exhaust gas is fully removed. Likewise, at a medium load driving area, the opening of the valve 8 is controlled so as to make air-fuel mixture concentration in and around these spark plugs 11 and 13 turn into a lean side limitation in relation to the intake air quantity, and according to the engine load, fuel is ignited by both these spark plugs 11, 13. Therefore the extent of combustion efficiency is improved.

Also, an insulating material 20 contributes as the heat-insulating material for the low temperature part located in the vicinity of the cold head 11. In the susceptor 6 which is constituted as above, the cold head 11 is cooled when the cool-air accumulating substance 13 intrudes into the expansion chamber 12 through a small gap. Accordingly, the low temperature part of this device is limited to the neighborhood of the expansion chamber, and the heat insulation of the part entering into the etching chamber other than the cold head 11 can be obtained easily. Also, both of the He pipings 7 and 8 are normal temperature piping, and the use of low temperature piping, in which intrusion heat is strictly limited, is unnecessitated.
