Title: Micro and nanoporous metal structure
Inventor: KAARU SHIAAZUKI
IPC: B01D71/02
Filed: 1990-04-12
Abstract: PURPOSE: To obtain a uniform and open cellular micro- and nano-porous metallic structure by bringing an alloy of metals varying in electrochemical activity as an anode into contact with an electrolyte and eluting the electrochemically active metals from the alloy.  
     CONSTITUTION: The prescribed ratio of the alloy of the at least two metals varying in the electrochemical activity is brought into contact with the electrolyte. The alloy is used as, for example, a binary alloy, etc., contg. 60 to 80% base metal and 40 to 20% noble metal. In the case of the binary alloy of silver and gold, 74% silver and 26% gold are adequate. Perchloric acid or nitric acid is used as the electrolyte at this time. Electrochemical potential is then imparted as the anode to the alloy in contact with the electrolyte. As a result, the electrochemically active metals are completely or partly eluted from the alloy to allow the porous metal to remain. The porous metal is heat treated for a prescribed time at need by which strength is imparted thereto. As a result, the metallic structure having uniform and internally communicated pores of about 3nm to 10μm size in pore size is obtd.

Title: Electronically controlled fuel injection device
Inventor: YUZURIHA YOSHIKI
IPC: F02D41/14
Filed: 1982-06-09
Abstract: PURPOSE:To effectively prevent chattering, by providing such an arrangement that a range of increase in fuel amount is judged in accordance with the open degree of the throttle valve, hysterisis is given to the initial and complete points of the increase, and the rate of the increase is determined in accordance with the rotational speed of an engine. CONSTITUTION:A first comparator circuit 15 issues an H-level signal when the open degree of throttle valve is larger than a first predetermined open degree alpha1. Further, a second comparator circuit 16 issues an H-level signal when the open degree of the throttle valve is less than a second predetermined open degree alpha2. A flip-flop circuit 17 is reset by the first and second comparator circuits. Thereby, the characteristics of increase in fuel amount may have hysterisis. A fuel amount increase compensating circuit 12 converts a fuel injection amount signal S2 which is computed by an arithmetic circuit 6, into a pulse width (1+K). Pw, where K is the rate of the increase which varies in accordance with the rotational speed of the engine. Thereby, chattering may be prevented.

Abstract: PURPOSE:To accelerate the returning action of handle by feeding a reverse assist current to an electric motor to apply a brake to the electric motor from the completion position of the cutting action of the handle to the steering neutral position, and applying the return assisting force to a steering system. CONSTITUTION:When a handle is cut to the left direction, for example, the rotation of the handle is detected by a handle action detecting sensor 9, and an assist current based on the preset characteristic is fed to an electric motor 1 by a CPU 10. The steering assisting force is applied to a rack 4 by the electric motor 1 via a pinion gear 3. When the cutting action of the handle is stopped and the CPU 10 judges the completion of the cutting action, the assist current is fed in the opposite direction to the above for the period corresponding to the rotating speed of the motor 1, and a brake is applied in the direction to negate the rotary inertia force of the motor 1. When the handle starts to be returned in the opposite direction, the CPU 10 feeds the reverse assist current to the electric motor 1 to apply the return assisting force to the rack 4.

Abstract: PURPOSE:To enable prevention of lowering of detecting precision, by a method wherein conversion characteristics, serving to provide an intake air flow rate from an output signal from an air flow rate sensor, is changed depending upon the opening of a bypass passage running around a throttle valve. CONSTITUTION:In a microcomputer 2 in an engine control device 1, the table value of an actual intake air flow rate responding to an output signal from an air flow rate sensor formed with a hot wire 20 is previously set as first characteristics when the opening of bypass passage 12 is fully opened and as second characteristics when fully closed. Based on first and second intake air flow rate data referred from a table and control signal duty ratio data of a bypass valve 31, computing processing is effected to compute an intake air flow rate responding to an air flow rate sensor output signal. This constitution, even if the opening of the bypass passage 12 running around a throttle valve 34 is changed, corrects a change in characteristics of an intake air flow rate due to a change in opening.

Abstract: PURPOSE:A control circuit with no misoperation at keyless lock time. CONSTITUTION:When all doors are detected locked and closed, a room lamp 20 is immediately put off. Consequently, signals of a door detecting switch 10 and a door lock detecting switch 12 are input to an OR gate 34, but a delay circuit 50 is inserted into an input route from the door open/close detecting switch 10. Thus, timing of an L output from the OR gate 34 can be delayed. Then, off-timing of a transistor 40, putting off the room lamp 20 by the output L of this OR gate 34, can be delayed. In this way, generation of the L output from the OR gate 34, in the case of releasing a door lock at door closing time, can be prevented.

Filed: 1979-08-06
Abstract: PURPOSE:To obtain a uniform and preferable epitaxial layer by easily controlling and operating an etching gas on Ga1-xAlxAs surface by employing HCl instead of GaCl. CONSTITUTION:A conventional method of producing GaCl from the reaction of AsCl2 with Ga melt difficult to control the temperature of the AsCl3 with high toxicity and difficult operation. When a furnace is uniformly heated in temperature distribution using HCl and a Ga1-xAlxAs substrate is etched by bringing it directly into contact with the substrate, the HCl can be fed into the furnace as retained at room temperature. When Ga1-xAlxAs or GaAs is epitaxially grown in vapor phase on the etched substrate, it improves the crystallinity. In this case, the substrate is retained at 750-850 deg.C with HCl density of 0.01-1%. It may be retained at 830- 850 deg.C with 0.01% of HC for approx. 3min, and with 1% of HCl for approx. 0.06min. If the temperatue is raised higher than 850 deg.C, the surface of the substrate is roughed, while if the temperature is lowered lower than 750 deg.C, it is irregularly etched. If the HCl is contained higher than 1%, the surface of the substrate is roughed, while if it is contained lower than 0.01%, it is difficult to control the HCl. This configuration can obtain uniform epitaxial layer with preferable crystallinity.
