Title: Automatic constant speed traveling device
Inventor: YOSHIMURA HIROSHI
IPC: F02D41/00
Filed: 1985-06-10
Abstract: PURPOSE:To obtain the optimum fuel injection in accordance with either 'power' traveling or 'economy' traveling by providing a power/economy changeover switch, detecting the operation of this switch at the time of resuming operation, and controlling the flow rate of fuel to be the optimum value. CONSTITUTION:When a main switch 20 is pressed to start a constant-speed control while a car is traveling, and as a resume switch 21 is set to a set side, then the car speed which is detected by a car speed sensor 10 is read as a set car speed by an ECU 13, to obtain a car speed deviation DELTAV. Then, a power/ economy changeover switch 22 is checked for its switched direction and, when positioned on the economy side, a proportionality factor used for calculating the flow rate of fuel is defined as KP and an integral factor as KI, whereas, on the power side, the factors are defined as KPalpha, KIbeta respectively. And, the flow rate of fuel is operated using above mentioned factors and the deviation DELTAV, etc. to inject fuel with a flow rate corresponding to either 'economy' traveling or 'power' traveling, to an engine 1.

Abstract: PURPOSE:To increase the active-material holding ability of a plate used for a lead storage battery by sticking two pieces of expanded metals together with pressure so as to make a grid, and packing the grid with an active material so as to make the said plate. CONSTITUTION:After expanded metals are prepared from two pieces of metal sheets, the expanded metals are fixed together by pressure with their pitches shifted by about 1/2. Following that, a lug 6 and the like are formed by punching work so as to make a grid, and an active material 10 is packed into the grid. After that, the grid packed with the material 10 is dried and cut so as to make a unit plate 13.

Abstract: PURPOSE:To make identical the resistance values of two polycrystalline silicon resistance films by a method wherein hydrogen ion blocking films are respectively provided between insulating oxide films and the resistance films. CONSTITUTION:Hydrogen blocking films 21, which do not make hydrogen ions pass through, are respectively provided between a first insulating oxide film 5 and a first polycrystalline silicon resistance film 8a and between a second insulating oxide film 4 having a thick film thickness and a second polycrystalline silicon resistance film 8a.
