Title: Fuel control device
Inventor: MORITA KIYOMI
IPC: F02D41/24
Filed: 1986-04-09
Abstract: PURPOSE:To prevent the fluctuation of a control value near a boundary by outwardly spreading the boundary of an area to bring about hysteresis only when said control value has moved from the specified area to the adjacent area, of a matrix type map. CONSTITUTION:A learning area map has an N-axis lattice point housing areas N1-N4 on an engine speed table. It also has a Tp-axis lattice point housing areas Tp1-Tp4 on a basic injection pulse axis table. In this case, even if a control value has deviated from the solid line part indicating an area number (a, b) to the adjacent part by an amount DELTA, it does not mean that the control value is changed to the area adjacent to the area numbers (a, b). In other words, the boundaries of an area are spread out in all sides by DELTAN, DELTATp, and the control value is not changed in the case of change by amounts DELTAN or DELTATp. A what is called two sensitive band is formed, thereby, preventing the fluctuation of the control value near the boundary of an area.

Title: Cooking heater
Inventor: OGAKI MASAYOSHI
IPC: F24C15/16
Filed: 1985-04-17
Abstract: PURPOSE:To enable to automatically and safely take a cooking dish out of a heating chamber by forming a constitution wherein a means to push the cooking dish out of the front opening of the heating chamber by means of an energizing means and a damper interlocking with the energizing means and a locking means to hold the cooking dish in the heating chamber are provided. CONSTITUTION:During the pushing out of a dish 2, a driving arm 5 is pivoted in the direction indicated with the arrow 11 by means of a spring 7. The pivoting motion of the driving arm 5 is transmitted through a pin 13, a transfer rod 8 and a pin 15 to the rotating arm 14 of a damper 9. Because the damper 9 is so constructed as to produce the resistance proportional to the rotary speed of the driving arm 5 with respect to the rotation in the direction indicated with the arrow 16 (and to produce no resistance with respect to the rotation in the direction indicated with the arrow 17), the rotary speed of the driving arm 5 becomes nearly constant and consequently the dish 2 is pushed out at slow speed. Next, when the dish 2 is inserted in the heating chamber, the one end 20 of a releasing lever 19 abuts on the rear side slope (a) of a projection 18 and finally climbs said slope completely and is caught by the steep front side slop (b) so as to be locked in a heating chamber 1. The locking is released by sliding an operating knob 24 in the direction indicated with the arrow 28 by a user and the dish is pushed out at slow speed by means of a pushing-out means.

IPC: G02B6/24
Filed: 1980-06-17
Abstract: PURPOSE:To perform melt-sticking of aligned axial lines with simple and inexpensive constitution by providing a mirror which projects the joint part of optical fibers insertably between the optical fibers and electrodes. CONSTITUTION:Optical fibers A1, A2 are set to support tables 4, 5, and exposed parts B1, B2 are opposed in the position between electrodes 10, 11. When a mirror solenoid 25 is energized, a movable iron core 26 is lifted, and a mirror supporting table 20 is turned in an arrow (a) direction around a pin 21, by which a mirror 23 is inserted into between the joint part of the parts B1, B2 and an electrode 16 at a 45 deg. angle of inclination. The operator observes the top surface of the joint prt of the parts B1, B2, and the side face projected on the mirror 23, and aligns the axial lines. When the solenoid 25 is deenergized, the mirror 23 is reset by a spring 28. Discharge is caused between the electrodes 10 and 11, thereby melt- sticking the parts B1, B2. Thus, the melt-sticking of aligned axial lines is accomplished with the simple and inexpensive constitution.

Filed: 1993-04-08
Abstract: PURPOSE:To obtain the metallic lustrous face presenting fine appearance by providing a cast aluminium alloy wheel, a chrome plated layer formed on the design face, and a transparent clear finished layer formed on the surface of the chrome plated layer. CONSTITUTION:An aluminium wheel 1 is manufactured by applying alkaline cleaning and chemical conversion treatment to cast raw material manufactured of an aluminium alloy. Chromate treatment, for instance, can be applied as the chemical conversion treatment. Chrome plating is applied to the design face of the pretreated cast raw material 2 to form a chrome plated layer 3. The chrome plated layer 3has the metallic lustrous face because of Cr plating obtained by substrate-plating metal such as Cu or Ni into appropriate thickness (50-60mum) and then applying thin chrome plating (1-2mum) to the surface. For clear finishing, water soluble or solvent type resin coating material such as acrylic resin, polyester resin or melamine resin can be used to form a film of 10-30mum in thickness.
