Title: Front and rear wheel transmission in four-wheel drive vehicle
Inventor: TANAKA HIROHISA
IPC: F16H61/02
Filed: 2000-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a front and rear wheel transmission in a four wheel drive vehicle which can effectively employ the change gear ratio range by determining a target change gear ratio of the variable speed for the rear wheels obtained in response to the width of the steering angle on the basis of the target change gear ratio of the variable speed for the front wheels. SOLUTION: So as to avoid tight corner brake phenomena caused by steering, a controller 30 is adapted to additionally correct a target tilted and rotating angle ϕcr for rear wheels in variable speed for the rear wheels which is calculated according to the driving situation of a vehicle on the basis of the steering angle ζdetected by a steering angle detection sensor 18, so that the target tilted and rotating angle ϕcf for the front wheels is calculated and set in the variable speed for the front wheels. When the vehicle is driven at a slow speed in a wide steering angle, an additional margin for shift toward speed reduction side is not required for the target tilted and rotating angle ϕcr for the rear wheels which has been shifted to the speed reduction side, so that the range of the change gear ratio can be effectively utilized.

Title: Fluorescent character display tube
Inventor: MIZOHATA TADASHI
IPC: H01J29/88
Filed: 2000-05-29
Abstract: PROBLEM TO BE SOLVED: To realize a fluorescent character display tube that has a face plate of half-mirror state on the entire surface, makes the bonded part invisible from the outside in the form of a frame, and a higher level of electrostatic shielding, electron diffusion and heat radiation effect. SOLUTION: The half-mirror state is obtained by forming an aluminum film 52 on the entire back side of a face plate 51. Since other aluminum films 641 and 642 are formed separately between the aluminum film 52 and the face plate 51, change in color of the aluminum film 52 caused by sealing adhesive glass 63 cannot be seen through the face plate 51. Since the sealing adhesive glass 63 is filled in a hole 643 of the aluminum films 642 and 52, the face plate 51 adheres to a side plate 62 surely. A contact lead 71 is brought into pressure contact with the aluminum film 52 at a position of the aluminum film 642.
