Title: Method of controlling learning of air-fuel ratio of internal-combustion engine
Inventor: ITOU TOSHIMITSU
IPC: F02D41/14
Filed: 1983-05-09
Abstract: PURPOSE:To prevent a value for the idling of an engine from being improperly learnt, by allowing the learning of the value when a throttle valve is entirely closed, the load upon the engine is larger than a prescribed level and the rotational frequency of the engine and the speed of a vehicle are lower than prescribed levels. CONSTITUTION:A basic fuel injection period TP determined in terms of the load (intake pipe pressure PM or sucked air quantity Q/NE per rotation of an engine) upon the engine and its rotational frequency is compensated by an air-fuel ratio feedback compensation coefficient FAF obtained on the basis of the output signal of an O2 sensor for detecting the residual oxygen concentration of exhaust gas, so that the air-fuel ratio of a mixture is controlled to be equal to an aimed value. It is judged whether a throttle switch is on. If it is judged that the switch is on, it is judged whether the rotational frequency NE of the engine is lower than a prescribed level, the load upon the engine is larger than a prescribed level and the speed of a vehicle is lower than a prescribed level. Only when it is judged that the rotational frequency is lower than the prescribed level, the load is larger than the prescribed level and the vehicle speed is lower than the prescribed level, learning is controlled so that the air-fuel ratio feedback compensation coefficient FAF approaches a predetermined value.

Title: Optical recording medium and write protect method therefor
Inventor: AIHARA KENICHI
IPC: G11B7/24012
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To execute write protect and its release for many times with a single optical recording medium. SOLUTION: This phase transition optical recording medium 101 is provided with a reversible display layer 103 at a position covering a program memory area(PMA) 102. The reversible display layer 103 is formed of a thermal reversible material to reversibly change light transmissivity into two kinds at least at the time of recovery at ordinary temperature corresponding to a heating temperature. Thus, by turning the reversible display layer 103 into low light transmissivity, the write protect of the optical recording medium 101 is executed and by turning the reversible display layer 103 into high transmissivity, that write protect is canceled. In this case, since the reversible display layer 103 reversibly changes its state, the write protect and its cancel can be executed over and over.

Title: Drawing furnace for optical fiber
Inventor: SAKAGUCHI SHIGEKI
IPC: C03B37/029
Filed: 1981-05-29
Abstract: PURPOSE:To prevent impurity particles in a furnace for softening a glass base material for an optical fiber by heating and for drawing it into a fiber, from sticking to the surface of a base material, and to obtain an optical fiber with uniform and high strength, by applying a voltage to a grid between a heating element and the base material in the furnace. CONSTITUTION:A base material 1 is gradually fed into a furnace 6 and softened by heating with a heating element 3. In the temp. region over the softening point of quartz glass, that is, the heating region, the diameter of the material 1 is made smaller, and the material 1 is continuously drawn into an optical fiber 2. At this time, a high temp. is necessary for the material 1, and the temp. of the element 3 is made higher than that of the material 1, so the element 3 is dissipated to produce carbon particles. Impurity particles are also produced from a heat insulator 5 such as carbon wool. Since these particles are positively charged and the base material 1 is negatively charged, the particles stick to the surface of the material 1. By putting a slit-contg. cylindrical grid 4 made of carbon between the element 3 and the material 1 and applying a voltage to it from a voltage generator 8, the particles are repelled or attracted to the grid 4 in accordance with the positive or negative and the degree of the voltage.

Filed: 1986-04-09
Abstract: PURPOSE:To feed a group of paper sheets placed one by one from the uppermost one, by providing a drawing belt for drawing upward the edge of the group of the paper sheets at the side of a paper feed direction. CONSTITUTION:A drawing belt 12 rotates at a speed higher than the motion in a moving direction of a paper sheet placing unit 17 for drawing the group of paper sheets. Since the area of a paper sheet contacting the drawing belt 12 is very small, the group of the paper sheets 18 has its end surface at the side of a paper feed direction lifted slightly. A fine dislocation is caused among the respective paper sheets in the group of the paper sheets 18 and a larger dislocation is caused at the upper portion by the same force as compared with the lower portion due to the effect of the weight of the respective paper sheets as far as the entire group of the paper sheets 18 is concerned. As a result, the group of the paper sheets placed on the paper sheet placing unit 17 can be bed one by one from the uppermost one with ease, whereby they can be fed into a feed roller 14.
