Abstract: PURPOSE:To get a proper air-fuel ratio at all times by calculating a fundamental increment factor when car speed is reached to the setting car speed at vehicle starting, adding a constant starting increment factor to this fundamental factor for calculating a starting increment, and adjusting the starting increment as gradually reducing the starting increment factor. CONSTITUTION:At the time of driving an internal combustion engine, in a control means 16 which inputs each output signal of a throttle sensor 10, a car speed sensor 12, a water temperature sensor 14, an intake air quantity sensor and an engine speed sensor 18, first of all, when a vehicle is starting and car speed is reached to the setting one, a fundamental increment factor is calculated according to cooling water temperature. In addition, a starting increment factor is set to a constant value, while a timer of the control means 6 is started, a constant starting increment factor is added to the fundamental increment factor, thereby calculating the starting increment quantity. Then, the starting increment is added to the fundamental fuel quantity being calculated from the intake air quantity, calculating the total injection quantity, and a fuel injection valve 8 is driven and controlled. In this connection the starting increment is regulated in a way of reducing the starting increment factor by degrees in proportion as time elapsing.

IPC: G01D5/16
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To achieve a miniaturization and a saving of power by a method wherein an inverting amplifier comprising a CMOS inverter is connected in series in odd stages to guarantee the linearity of an input/output relationship as expressed by a specified formula and an impedance as sensor is connected between the input and the output or to the input. SOLUTION: For example, a sensor circuit is formed using two capacitance type sensors Cap31 and Cap32 and the input and the output of an inverting amplifier comprising three stages of CMOS inverters I131-I133 is connected by the Cap32 and the Cap31 is connected to the input of the inverting amplifier. When an input voltage to the Cap31 is represented by Vin and an output voltage from the inverting amplifier by Vout, an input/output relationship is as given by a formula [I]. Thus, the output voltage is proportional to the ratio of the Cap31 and the Cap32 and when changes opposite to each other are caused in the Cap31 and Cap32, the changes are amplified and outputted.

Filed: 1991-06-29
Abstract: PURPOSE:To save a labor of a measurement for use and reduce cracking after a cement is cured by a method wherein a cement mixing material and/or mixing agent is packaged by a packaging material made of high-strength paper containing a sizing agent or a paper strength increasing agent, and the obtained package is put into a cement mixture and agitated for beating the packaging material. CONSTITUTION:A packaging material is obtained by adding a sizing agent or a paper strength increasing agent to a raw material for paper or a pulp sheet containing a cellulose fiber, or alternatively by adding a sizing agent or a paper strength increasing agent to prepared paper. As another preferable alternative, a polymer substance dissolving or disintegrating in an alkaline solution is applied or laminated on the paper. Every generally-known cement mixing material (agent) can be used to be packaged by the packaging material. The package is agitated together with a raw concrete or the like, e.g. in a drug agitator, thereby being dissolved or beat to be uniformly mixed. The fiber substance forming the packaging material functions to reduce a cracking amount on the cured cement surface.

The second FET is a dual gate FET or a single gate FET having >=2mum gate length. The GaAs FET having a single gate 8 whose gate length 11 is made longer or dual gates 8 and 8' shown in a figure C is used as an active load. Then, the high frequency impedance of the active load itself is increased to reduce the noise. Thus, the active load is used instead of the chock coil without degrading the noise characteristic, and monolithic integration of a high frequency circuit is possible.
