Whether or not quantization data in a reference area in an original read area at original reading reach a full scale output of an A/D converter 28 is compared by a comparator 33, increment or decrement of a multiplier coefficient is commanded depending whether or not the data reach the full scale, a prescribed increasing decreasing rate is added to a multiplier coefficient in a preceding scanning by an adder 33 and the result of sum is outputted to a multiplier coefficient register 36 as a multiplier coefficient of a succeeding scanning. Dark correction data are subtracted from bright correction data at a subtractor 41 and the said multiplier coefficient is multiplied with the result of subtraction. Furthermore, the result of sum of the dark correction data is outputted to a D/A converter 26 as a white reference level. The quantization of an analog image signal is performed from the white and black reference levels.

Title: Steering device
Inventor: SUZUKI TADAYUKI
IPC: B62D6/00
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption of a motor by setting a gear ratio when an actuator is not operated between the median of a prescribed range and a lower limit value of the prescribed range. SOLUTION: A gear ratio (basic gear ratio GB) when a variable gear ratio actuator is not operated is set between a median GCNT of the prescribed range and a lower limit value GMIN of the prescribed range and GMIN<=GB<=GCNT is determined. The setting of this basic gear ratio GB is transmitted to an output side by amplifying the rotation of an input side as a fixed gear ratio mechanism. At the time of a low speed traveling, a distance B from the basic gear ratio GB (initial value) to a target gear ratio (target value) is small. Therefore, the number of revolution of a motor transferring the gear ratio G from the basic gear ratio GB to the target gear ratio may be reduced. Thus, a motor output at the time of the low speed traveling is reduced and power consumption is reduced.  Because a steering frequency of a steering wheel at the time of the low speed traveling is larger than that at the time of a high speed traveling, the reduction of power consumption becomes effective.

Title: Low pass filter for digital circuit
Inventor: NOBUE TETSUAKI
IPC: H03H17/02
Filed: 1983-09-02
Abstract: PURPOSE:To obtain a flat frequency characteristic by setting a constant of elements constituting a filter circuit so as to cancel a high frequency attenuating characteristic due to the aperture effect. CONSTITUTION:The frequency gain is decreased at a higher frequency because of the relation between a sampling frequency and a signal frequency due to the aperture effect in converting a digital signal into an analog signal in a digital audio circuit or the like. To correct the attenuation of the signal, the constant of elements constituting the low pass filter is set properly so as to constitute the frequency characteristic that the gain is increased up to 20kHz being the audible band and the gain is attenuated steeply at a frequency over 20kHz. Thus, a flat characteristic is obtained as the overall frequency characteristic and a high frequency boosting circuit or the like is not required.

Title: Dry etching of silicon using bromine gas
Inventor: MIHARA SATOSHI
IPC: H01L21/302
Filed: 1987-07-01
Abstract: PURPOSE:To etch without hole bottom roughness and hole depth irregularity with good reproducibility by removing a natural oxide film on the surface of a silicon before the reactive ion etching of the silicon is conducted with bromine gas. CONSTITUTION:An SiO2 film 12 is formed on the whole surface of a silicon single crystalline substrate 1. A resist film 13 is formed thereon, exposed in a predetermined pattern, and developed to form a window 14. With the film 13 as a mask the film 12 is selectively removed by reactive ion etching with fluorine gas (CF4, CHF3, etc.) to form an opening 15. The film 13 is removed with a solvent or the like. When a silicon substrate 11 is handled while the resist film is removed or after the resist film is removed, a natural oxide film 16 is generated on the exposed surface of the substrate 11. The oxide film is removed by dry etching with fluorine gas or chlorine gas. Then, a hole 17 having no roughness at the bottom is obtained by reactive ion etching for silicon trench etching with bromine gas substantially vertically on the sidewall.
