Title: Projection display device
Inventor: KONISHI TAKAYA
IPC: G03B21/00
Filed: 2001-10-10
Abstract: PROBLEM TO BE SOLVED: To prevent a light source of a projection display device from not being cooled sufficiently. SOLUTION: When a fan F is actuated, cold air outside the device is sucked into the device as shown by the arrow to cool the light source 1. The air which cools the light source 1 to become warm passes by the fan F and through an air vent 52 to enter a 2nd passage 50 of a screen frame 5 and is discharged from an outlet 51. The air is made flow upward from the light source 1 to the 2nd passage 50 and the outlet 51 is formed above the 2nd passage 50, so the air which is made warm is discharged to the outer side without staying in the 1st passage 41 nor the 2nd passage 50. The cooling efficiency is therefore improved and the light source 1 can be cooled sufficiently.

Title: Governor for in-line injection pump
Inventor: MAKITA YOSHIKAZU
IPC: F02D1/08
Filed: 2001-10-12
Abstract: PROBLEM TO BE SOLVED: To solve the problem that size, cost and adjustment man-hour are increased to obtain reverse Angleich characteristics with a mechanical mechanism in a conventional RSV governor and that productivity is low since design is done with matching engine characteristics. SOLUTION: A linear drive type stepping motor 12 is loaded on a boost controller installation position and drives a control rack 4 to a side reducing fuel. Reverse Angleich characteristics are thereby easily provided without a trouble such as body enlargement. Since start up characteristics and full characteristics are freely controlled by settings of an ECU 16, the control rack 4 is set at an optimum position according to start up temperature to improve startability. Since the governor is applied to many types of engines by changing setting of the ECU 16, productivity is not deteriorated.
