Title: Method for controlling color balance for multicolor image forming device
Inventor: SUZUKI HIROHARU
IPC: H04N1/46
Filed: 1988-05-09
Abstract: PURPOSE:To obtain excellent color balance by correcting the adherent amount of toner when the toner of at least one color fluctuates to be out of a toner concentration allowable range previously set in a developing device by setting the adherent amount of the toner of said color as a reference and correcting that of the toner of other color according to its reference. CONSTITUTION:As to the adherent amount of the toner such as yellow, magenta and cyanogen, when that of the toner of one or more colors becomes out of the toner concentration allowable range and fluctuates to such an extent that correction must be performed, the correction is performed so that the color balance can be obtained by setting the color which is deviated most within the toner concentration allowable range as the reference. For example, when the adherent amount of yellow toner fluctuates to be like a curve J and those of magenta and cyanogen are still like a curve H, the set value of a toner concentration sensor is corrected so that the toner concentration of a developing device 10 becomes larger according to a signal showing that the concentration is low, outputted from a photoelectric sensor 18 for a yellow image. Thus, the color balance can be stabilized under all the conditions.

Filed: 1984-05-31
Abstract: PURPOSE:To prevent the charging of static electricity, which is generated when a semiconductor substrate is transferred from the previous process to the succeeding process, and to prevent the occurrence of defects in a semiconductor device due to the breakdown of a gate, by forming a conducting film on the semiconductor substrate, whose previous process is finished, and shorting the part between mutual outer lead terminals. CONSTITUTION:On a semiconductor substrate 11, a semiconductor device including an MESFET12 is formed in the previous process. When the semiconductor substrate 11 is transferred to the succeeding process, a conducting film 24, e.g., Ti, is formed on the semiconductor substrate 11 by an evaporation method to a thickness of 400Angstrom . A conducting film 23 is removed. In this way, the rate of defects, which are yielded during the transfer from the previous process to the succeeding process, is decreased. This effect is very conspicuous in the semiconductor device having a gate, which is electrostatically damaged easily, such as GaAs MESFETs or Si MOSFETs.

Title: Forming method for resistance region
Inventor: SUDOU TAKEYUKI
IPC: H01L27/04
Filed: 1979-08-31
Abstract: PURPOSE:To improve the accuracy of the value of resistance by a method wherein a resistance region is geometrically limited by V-grooves in which a heat resisting insulating material is filled when forming the resistance region of an integrated circuit device. CONSTITUTION:V-grooves 5 are made up on a semiconductor substrate 1 so as to limit an element region 2'. The difference of the speed of etching due to the difference of a surface direction of a substrate crystal is utilized for the formation of the V-grooves. A heat resisting insulating material 6, such as Si3N4, SiO2, Al2O3, etc. is filled in the V-grooves 5 by means of a CVD method. When forming resistance to the element region, ions are successively implanted to the element region, necessary impurities are introduced, and necessary resistance value is obtained. Thus, the element region is limited by the V-grooves, the element region do not vary in a process of heat treatment, and consequently resistance having high accuracy is acquired. Not only resistance but also other elements may similarly be made up in the element region. The V-grooves may be exchanged for U-grooves.

Title: Storage conveyor device of truck
Inventor: MATSUSHITA TOSHIHIRO
IPC: B65G17/24
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To stop a central position of a truck in the longitudinal direction at a desired work position accurately and easily by making a rotation resistance value of a conveyance roller of a truck conveyance chain arranged on one side higher than a rolling resistance value of a running wheel which rolls on a running track arranged on the other side. SOLUTION: When a truck conveyance chain 3 is conveyed and driven, a conveyance roller 4A having high rotational friction resistance due to a slide bearing is mixed in a row of conveyance rollers 5A having low rotational friction due to an rolling bearing in the truck conveyance chain 3. For this reason, it is possible to make rotational friction resistance of conveyance rollers 4A, 5A for a truck higher than rolling friction resistance of a truck running wheel having the rolling bearing. The truck moves together with the truck conveyance chain 3, and speed of the truck is increased more than a travel speed of the chain 3 when a double speed conveyance roller is used for conveyance. When the truck is stopped due to external force, the conveyance rollers 4A, 5A rotate in idling and pass a support face of a shoe member to allow the travel of the truck conveyance chain 3.

Title: Magnetic disk device
Inventor: MIYASAKA HITOSHI
IPC: H02P29/00
Filed: 1986-05-15
Abstract: PURPOSE:To attain a speed control with high accuracy, by reproducing the seek speed of a magnetic head at a speed signal reproduction circuit, taking a difference between a reference signal after passing a reproduced speed signal through a notch filter, or a low-pass filter, and inputting it to the driver circuit of a magnetic head seek mechanism. CONSTITUTION:The notch filter, or the low-pass filter for suppressing the vibration of a mechanical resonance point is placed at the front stage of a subtraction circuit. Since an error signal after the subtraction circuit is not passed the filter, the lowering of the gain, or the phase delay of the error signal is not generated, and a superior traceability for the speed reference signal of a seek speed signal in the magnetic head can be obtained. In this way, the error signal between a signal which is the seek speed signal passed through the notch filter, or the low-pass filter, and the speed reference signal, can be inputted to the driver circuit without lowering the gain, or delaying the phase.
