Title: Electronic control fuel injection device for internal-combustion engine
Inventor: KASATSUGU MITSURU
IPC: F02D41/00
Filed: 1985-10-28
Abstract: PURPOSE:To make an air-fuel ratio preventable from going to overrichness at the time of reacceleration, by compensating a fuel increment for reduction at a time when the reacceleration takes place within the specified time after acceleration. CONSTITUTION:In case of an internal-combustion engine 1 fitted with a fuel injection valve 4 proximate to a throttle valve 3, when a variation in throttle valve opening to be detected by a throttle sensor 16 is positive, an accelerating fuel compensation increment is calculated by a control unit 8. Here, when a fact that acceleration elapses as long as the specified time and reacceleration is carried out within the specified time after acceleration are detected, the accelerating fuel compensation increment is multiplied by a reaccelerating increment compensation factor of less than 1, and the reaccelerating fuel compensation increment set by reduction is added to a fundamental fuel quantity. With this constitution, undue supply due to fuel being increased in quantity at the time of acceleration before reacceleration and sticking to the wall of a suction passage 2 is restrainable.

Title: Electrode plate for separating harmful metals in sludge and separator using the electrode plate
Inventor: KAJIWARA YASUNOBU
IPC: C02F1/461
Filed: 1994-09-06
Abstract: PURPOSE: To produce an electrode plate capable of easily separating the harmful metals in sludge by covering the outer face of a magnet as a core with an iron material. CONSTITUTION: A magnet 1a is used as a core plate, and an iron electrode 1b is provided on the front and rear to constitute an electrode plate 1. Many electrode plates 1 are arranged in an electrolytic cell 2, a current is applied to the electrode plate 1 from a power source 3, and sludge is supplied into the cell 2 from an inlet 5 and discharged from an outlet 6. Consequently, the generated ferrite is collected on an electrode (positive electrode), the contact frequency with the heavy metal ions in the sludge is increased, and the ferrite is grown on the electrode surface. Although the substances other than ferrite are also simultaneously deposited as scales, the scales are released by changing the polarity of the electrode plate 1 with a polarity changing device 4. The harmful metals such as heavy metals contained in the sludge are separated and removed in this way.

Title: Method for automatically controlling electroless nickel plating solution
Inventor: TSUGE YOSHIO
IPC: C23C18/32
Filed: 1988-09-26
Abstract: PURPOSE:To prevent the unexpected plating and deposition of Ni and to automatically control an electroless Ni plating soln. by changing the pH, Ni concn., and temp. as the number of turns increase, and appropriately interlocking the supply of the pH regulator and Ni component. CONSTITUTION:The pH, Ni concn., temp., etc., are changed with the changes in the components of the electroless Ni plating soln. as the number of turns increase to fix the deposition rate and composition. In this method for automatically controlling the plating soln., the pH regulator is not supplied while the Ni component is supplied. When the temp. is rapidly elevated and a base heater is operated, the Ni component is not supplied. The supply of the components is interlocked in this way, hence unexpected plating due to a partial increase in pH and the deposition of Ni on a heater, etc., are prevented, and the plating soln. is controlled as the number of turns increase.

Title: Automobile constant speed running device
Inventor: MUROTA KAZUAKI
IPC: F02D41/14
Filed: 1984-11-14
Abstract: PURPOSE:To prevent an erroneous control where a car speed changes rapidly after an acceleration pedal has been returned by allowing the accumulation of set deviations to be integrated when an acceleration pedal is operated for a system where a deviation between a set duty and an actual duty is correctly integrated. CONSTITUTION:In a device as referred to the title, after F/V conversion 19 of a speed signal from a lead switch 13 is effected, it is inputted into a memory 21 through a switch 20 where an average voltage (set up car speed) for the stated period of time is stored by means of an averaging function in the memory 21. Then, a deviation between an actual car speed and the set up car speed is determined by a comparator 22, the output from which is applied to a solenoid coil 17 by way of a timing compensation circuit 23 which compensates the delay in mechanical operations of an actuator 16, and of a prohibiting gate 24 which is opened only when a car is running at a constant speed. Thus, a duty control on a control valve which controls the throttle opening, is allowed to be effected. In this case, when an acceleration pedal is pressed, its detected output E allows the operation of an integration circuit 40 to be discontinued once permitting its accumulation of set deviations to be interrupted.

Title: Dry etching method
Inventor: SATO JUNICHI
IPC: H01L29/812
Filed: 1992-09-09
Abstract: PURPOSE:To provide a dry etching method for GaAs/AlGaAs laminate in which particle contamination due to AlFx is prevented. CONSTITUTION:When a gate recess is made in a HEMT, an n<+>-GaAs layer 5 on an n<+>-AlGaAs layer 4 is etched using mixture gas of S2F2/S2Cl2. Consequently, Ga and As are removed in the form of fluoride and chloride, respectively, while S produced in vapor phase deposits to form a side wall protective film 7 and thereby a recess having anisotropic shape is formed. Etching is stopped when an AlFx layer 8 is formed on the exposed surface of the n<+>-A GaAs layer 4 under low vapor pressure. The AlFx layer 8 is removed, together with the side wall protective film 7, by heating a wafer at about 400 deg.C or it is removed after being converted into AlClx, A Brx, or the like under low vapor pressure using halogen radicals such as Cl* or Br*.
