Title: Measuring instrument equipped with function of automatically adjusting offset
Inventor: INAGAKI AKIRA
IPC: G01B21/30
Filed: 1991-07-02
Abstract: PURPOSE:To shorten the time for arrangement before actual measurement by automatically adjusting an offset value by means of calculation of the value from data at one part of a pre-area preceeding a measuring area or of the measuring area, the offset value being added to display, or printing, outputs. CONSTITUTION:In a measuring instrument which measures the surface configuration of a subject to be measured and displays or prints it, a pre-area preceeding a measuring area is set in order to avoid the transient response of a driving system. Because the properties of the pre-area for flat subjects to be measured resemble those of the measuring area, the average value of the pre-area approximates that of the measuring area. Therefore the average value of the pre-area is used as an output offset value so that offset adjustment is automatically carried out in such a way that a zero point on the display screen serves as a starting value of measurement. When the surface area of a subject to be measured is too small to provide a wide pre-area, data at some part of the measuring area may be averaged to compute an output offset value which is utilized to provide similar displaying or printing methods.

Filed: 1988-07-29
Abstract: PURPOSE:To reduce the tiredness that a driver's foot may feel during driving, by forming the face on which the foot is to be rest as a projecting curved face so that slippage may not arise no matter from what direction the foot is put thereon and that the foot may be naturally put thereon. CONSTITUTION:A foot rest 5 disposed in parallel with an axle pedal 2, a brake pedal 3 and a clutch pedal 5 has a surface 6 which is formed as a projecting curved face. Horizontal components may thus not arise when a driver puts his foot 7 thereon, so that the foot 7 is prevented from slipping sidewards. Also, this makes it unnecessary for the reverse face 8 of the foot 7 to be put on the projectingly curved surface 6 forcibly in parallel thereto so that the foot 7 can be naturally put thereon, for reducing the tiredness that the foot may feel.
