Title: Vehicle control device
Inventor: SHIRAKI TAKAHIRO
IPC: B60W10/10
Filed: 1999-12-06
Abstract: PROBLEM TO BE SOLVED: To enhance reliability of a vehicle control device equipped with a driving source control device to automatically stop and automatically start the driving source when the vehicle stops. SOLUTION: If the automatic stop condition of an engine is satisfied, a brake force holding command is supplied to a brake ECU. A parking brake 150 is actuated by the control of an electric motor 154 in a brake device. The parking brake 150 is actuated, and mechanical braking force is applied. Since a vehicle is kept in a stop condition by the mechanical braking force, reliability of this vehicle control device can be enhanced. In addition, since the condition is mechanically kept by a holding device 177, the mechanical braking force is applied even if operation of the electric motor 154 is stopped, and energy consumption under the stop condition can be reduced.

Title: Image forming device
Inventor: YOKOYAMA HIROSHI
IPC: G03G21/10
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To remove toner and paper powder adhering to the surface of a fixing roller by making the supply amount of an electric charge impressed by a charge supply means different based on whether a toner supporting body exists between a pair of fixing rollers or not. SOLUTION: The position of a transfer paper 1 is confirmed by a carrying side detection sensor 7, and a detection signal expressing that the paper 1 is carried to a fixing part is transmitted to a controller. The controller converts impressed charge supply amount outputted to a cleaning roller 5 from a voltage source 9 to the lower impressed charge supply amount in the case of receiving the signal. When the paper 1 passes through a fixing nip 10, a carrying side detection sensor 8 detects the paper 1, and transmits the detection signal to the controller. The controller changes the voltage of the source 9 to the original impressed electric charge supply amount based on the detection signal.  Consequently, while the paper 1 passes through the fixing nip part, a low impressed electric charge supply amount which does not disturb an unfixed toner image is set, and a high impressed electric charge supply amount is set in the case where the paper 1 does not exist on the fixing nip part.

Title: Laser unit and insulating block
Inventor: YAMAMOTO GOJI
IPC: G11B7/135
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To achieve low cost, simple, and accurate assembling. SOLUTION: A sub-mount to which a laser element is joined is die-bonded to the left side surface of an insulating block 30, and the lower surface of this insulating block 30 is jointed to the reference surface 18 of a package 16.
