Title: Control device for traveling of vehicle
Inventor: YASUKAWA TAKESHI
IPC: B60T7/12
Filed: 1987-04-22
Abstract: PURPOSE:To automatically select a constant speed traveling controllable area even on an ascent in addition to the constant speed traveling for a flat road traveling by judging a slope by means of a G sensor and enabling a normal constant speed traveling mode on a straight road or a gentle road. CONSTITUTION:Signals from a vehicle speed sensor 23 and a G sensor 24 are inputted into a microcomputer control unit 31. And, when an inputted deceleration is judged to be above a previously set first reference value, an ascent is detected. And, by checking whether an ascent was detected in an interruption processing one cycle before and when it was not detected, judgment is formed to be immediately after entering an ascent. And, when the deceleration of a vehicle is above the first reference value and below a second reference value, the vehicle speed V at the time of operating a resume switch is stored in a RAM 39 as a target vehicle speed Vc for constant speed traveling on an ascent. Further, when the deceleration becomes above the second reference value, a brake pressure is comparatively controlled with respect to the deviation in vehicle speed to deceleratingly control the target vehicle speed for constant speed traveling.

Title: Speed controller of motor driven vehicle
Inventor: SAITOU YOUICHI
IPC: H02P7/298
Filed: 1984-05-21
Abstract: PURPOSE:To improve the acceleration in a high speed range by flowing the prescribed field current to other field winding when the field current flowed to either one of forward and reverse field windings becomes the prescribed value or higher, thereby efficiently controlling the speed finely. CONSTITUTION:When a forward/reverse changeover switch 16 is shifted to a forward side F, a differential amplifier 12a applies a deviation signal between a signal in response to the depression of an accelerator pedal output from a variable resistor 11 and a field current from a current transformer 8a to a phase shifter 13a for controlling a chopper 9a connected with the forward field widing 3a. When the vehicle speed increases and the output value of the amplifier 12a increases, the output of a comparator 14a becomes ''1'' to close an analog switch 19a. Thus, the output of the resistor 11 is applied through a level converter 18a to the amplifier 12b to flow a field current to a reverse field winding 3b.

Abstract: PURPOSE:To vary optionally the gradation of an image according to an original or operator's choice by a simple operation of switches, by varying the electrostatic charge potential of a photoreceptor through at least either of a changeover switch and a variable resistor. CONSTITUTION:When the electrostatic charge potential of a photosensitive drum 1 is at 900 and 600V, saturated image density is about 1.4 and does not vary, but when original density is 0.5-1.0, a gamma value is different, i.e. high at 900V and low at 600V. Therefore, 900V is suitable for character images and 600V is suitable for photographic images. The electrostatic charge potential of the photosensitive drum 1 is varied by varying the voltage of a high-voltage power source 7 connected to a charged corotron 6 through the operation of the switch 8 on a control panel. At this time, the amount of exposure may be adjusted manually or automatically associatively with the switching of the high voltage.
