Title: Study control device for fuel injection amount in internal combustion engine
Inventor: UJINO MASATO
IPC: F02D41/14
Filed: 1987-08-11
Abstract: PURPOSE:To prevent a study value (acceleration increase coefficient) from generating a misstudy to a lean side, when an air-fuel ratio control frequently performs asynchronism in the transient time, by discriminating an air-fuel ratio rich condition by an asynchronous increase in the time of acceleration from the other rich condition. CONSTITUTION:An engine 20 is controlled by a microcomputer 44. The microcomputer 44, which inputs each detection signal respectively from sensors 4, 6, 8, 10, 16, 30, 34 of every kind detecting an operative condition of the engine 20, performs predetermined calculation. While the microcomputer 44 outputs a predetermined control signal to a fuel injection valve 24 and a spark plug 38. In this case each time deviation is calculated when the concentration of residual oxygen in exhaust gas is richer or leaner than the target air-fuel ratio. When this deviation comes to be out of the predetermined range during acceleration, an acceleration increase coefficient is corrected. While correction of the acceleration increase coefficient is inhibited until after the predetermined time from injecting fuel asynchronously with a crank angle during acceleration.

Title: Software error mount evaluating method for dynamic ram
Inventor: SATO YOSHIHIRO
IPC: G11C29/56
Filed: 1989-08-02
Abstract: PURPOSE:To reduce the number of input control signals and to enable the software error mount evaluation of a high-speed area by making a read cycle into an RAS only refresh cycle. CONSTITUTION:For the software error evaluating method of a dynamic RAM, instead of the execution of the read cycle for which RAS, CMA, row address and column address are required to be controlled, the RAS only refresh cycle is used and for the cycle, it is enough to control the RAS and row address only. Namely, Data are written over the whole surface of a cell and RAS only refresh is executed to the Data. Then, even when the data are inverted by software error, the data are held as the inverted data. Accordingly, when data decision is desired, the data are read. Thus, the software error mount evaluation can be realized in the high-speed area.

Abstract: PURPOSE:To heighten the corrosion resistance and hydrogen storage capacity of a hydrogen storage alloy and at the same time to heighten the corrosion resistance and charge and discharge capacity of a hydrogen storage alloy electrode composed of mainly the hydrogen storage alloy by introducing nitrogen atoms in metal lattice space of the hydrogen storage alloy. CONSTITUTION:Regarding a hydrogen storage alloy which can absorb and release hydrogen, nitrogen atoms are introduced into the metal lattice space of the alloy. The hydrogen storage alloy is used as a main component of a hydrogen storage alloy electrode for alkaline storage battery. In the hydrogen storage alloy, nitrogen atoms exist in the metal lattice space while breaking into the space and widening the distance of the metal lattice, so that the cell volume, which is a minimum unit of the metal crystalline structure, increases and hydrogen can invade the metal lattice space easily and the hydrogen absorption capacity is increased. Further, due to the increase of the hydrogen absorption capacity, the charge capacity of a negative pole of mainly the hydrogen storage alloy increases and at the same time since heat treatment is carried out when nitrogen is introduced into the metal lattice space, corrosion resistance of the hydrogen storage alloy is improved.

Filed: 1987-08-14
Abstract: PURPOSE:To obtain a large degree of freedom in tracking control, by enabling either a variable voltage circuit, a bias voltage attaching circuit, or a connection circuit to be adjusted variably. CONSTITUTION:In case of enabling the connection circuit 8 to be adjusted variably, since a variable voltage changes in a direction to be increased according to the change of a channel selection voltage in a direction to be increased, a difference between potential at both ends of a variable cpacitive diode 2 is reduced compared with a case where the channel selection voltage is applied only on the cathode of the variable capacitive diode 2, and a capacity for the channel selection voltage can be increased by the above reduced quantity. And the capacity to be increased is increased at a higher channel selection voltage side, and as a result, a variable capacitance characteristic for the channel selection voltage of the variable capacitive diode 2 can be corrected remarkably at a higher channel selection voltage area. Furthermore, it is possible to set the quantity of a capacitance to be correct arbitrarily by enabling a variable voltage circuit 5 to be controlled variably and performing a control operation. In such a way, it is possible to correct the variable capacitance characteristic of a tuning circuit 1 effectively extending over entire area of the variable range of the channel selection voltage.
