Title: Device for measuring stability of vehicle and method for adjusting stability
Inventor: KAWABE HIROSHI
IPC: G01M17/007
Filed: 1993-12-21
Abstract: PURPOSE:To measure and adjust stability without being affected by distortion, etc., of a vehicle. CONSTITUTION:The wheel of a vehicle 14 is placed on a placement stand 12 with a sensor for detecting a plurality of rollers where the rotary shafts are parallel and they are laid out so that they are directed in the horizontal directions and the force in the direction of the rotary shaft of the roller, and the force crossing the rotary shaft. While the roller of a rear wheel side is rotated, the attitude angle of the rear wheel is adjusted to minimize the force applied in the direction of the rotary shaft of the roller at the rear-wheel side. In this state, the attitude angle of the rear wheel is adjusted to minimize the sum of forces in the left and right direction of a front wheel and the difference in forces in the forward and rearward direction. Finally, the roller at the front wheel side is rotated and then the attitude angle of the front wheel is adjusted so that the force in the direction of the roller shaft of the front wheel can be minimized by rotating the rollers at the front wheel side. Also, wheels may be rotated one by one for adjustment so that the force in the direction of rotary shaft of the roller and the force in the direction crossing the rotary shaft may be minimized.

Filed: 1989-12-13
Abstract: PURPOSE:To hold accuracy high and stabilize frequency characteristics even when clamp amplifiers are decreased in gain by connecting the output sides of reverse current stopping diodes and the output sides of the negative feedback resistors of the clamp amplifiers directly to the input side of a main amplifier. CONSTITUTION:In the positive and negative clamp amplifiers 24 and 31, the output sides of the reverse current stopping diodes 26 and 33 and negative feedback resistors 42 and 43 are connected directly to the inverted input terminal of the main amplifier 13. Then the outputs of the amplifiers 24 and 31 are voltage-added by the amplifier 13 to omit a resistor for current conversion, and the diodes 26 and 33 are interposed in the negative feedback loops in the amplifiers 24 and 31 to eliminate the influence of their conduction voltage dops, thereby obtaining a voltage corresponding to the difference between a detected voltage and a set limit-value voltage. Therefore, even when the amplifiers 24 and 31 are decreased in gain, the accuracy can be made high and the gains are decreased to stabilize the gain-frequency characteristics of the whole system. Further, the band of the gain-frequency characteristic of the amplifier 13 is made wide and the response speed of variation to the set voltage or current is increased.

IPC: B41J2/525
Filed: 1987-12-23
Abstract: PURPOSE:To obtain an image processor in which economization of memory area is accomplished by obtaining a copy image in which a desired color image is regenerated by storing a correcting function for use in producing a look-up table, calling the correcting function as required, and referring to the look-up table. CONSTITUTION:When a print switch is switched on, a control device executes a command and allows original image information transferred in the form a RGB signals to be sent to a frame memory 10 from a CG device via a connection cable 6 so as to be stored in predetermined addresses in order. The control device then reads out the correcting function stored in a coefficient queue 16 and the original image information stored in the frame memory 10, and allows a computer 18 to produce a look-up table in which the original image information functions as an address. Thus, every time the print switch is switched on, look-up tables are produced, and this serves to economize the necessary memory area in a case where a plurality of look-up tables must be stored.

Abstract: PURPOSE:To connect a cabinet to a cover by means of an impedance by a structure wherein a contact tongue piece for a conductive elastic sheet which comes into close contact with the cover is brought into pressure-contact with a front frame at the cabinet. CONSTITUTION:In a state that a close-contact sheet member 21 has been brought into close contact with the surface of a cover inner-frame sheet 12, a conductive elastic sheet 20 is arranged and installed on a cover 10.
