Title: Back light and display device
Inventor: OGAWA KOZO
IPC: G02F1/13357
Filed: 2001-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a back light and a display device which easily obtain desired luminance symmetry in a hollow system and obtain a desired luminance without being made large-sized. SOLUTION: A back light 20 of a display device 10 is constituted of a light distributing means 1, a light emitting diode 1 provided in the vicinity of one end side 1c of the means 1, a reflection means which has a slope like a plane plate formed, and a hollow area 4 formed between the distributing means 1 and the reflection means 3. In this embodiment, the luminance symmetry of the back light 20 using the hollow system is easily improved because the reflection means 3 is so formed that its one end side 32 facing the light emitting diode 2 may be smaller than the part on the side of the light emitting diode 2. Since the loss of light emitted from the light emitting diode 2 is small, a desired luminance is obtained without increasing the size of the back light 20 using the hollow system.

Title: Vehicular driving torque control device
Inventor: HASEGAWA SATORU
IPC: F02D29/00
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To secure safety to nonconformance of accelerator operation and shift operation by erroneous operation of a driver. SOLUTION: After the initial setting, whether a shift position is an N range or a P range is investigated (S1 to S6), and in a non-travel range of the N and P ranges, an output torque command value is set to 0 (S9), and whether or not accelerator opening is larger than 0% is investigated by inputting an accelerator signal (S10, and S11). In accelerator opening > 0%, whether or not the shift position is shifted to R and D ranges is determined by inputting a shit position signal again (S12, and S13). As a result, when shifted to the R and D ranges from the N and P ranges, the output torque command value is set to 0 or creep torque (S14), a READY lamp 22 is flashed or turned on (S15).  Thus, even if the erroneous operation is performed to a travel range from the non-travel range while stepping an accelerator, driving torque of a vehicle is restricted to the creep torque or less to secure the safety.
