IPC: F02D41/04
Filed: 1991-04-26
Abstract: PURPOSE:To economize fuel consumption and increase travel distance by computing the fuel injection quantity in such a way as to make an air-fuel ratio at the idling time larger than an air-fuel ratio at the time of the fuel residual quantity being more than the specified value when the fuel residual quantity in a tank becomes less than the specified value. CONSTITUTION:When an internal combustion engine 7 during operation is judged by a control unit 15 to be in the idling state on the basis of the output of a crank angle sensor, a throttle sensor 18 and a neutral SW, the control unit 15 further judges whether the engine is in the air-fuel ratio feedback controllable state from the output of a water temperature sensor 20. In the case of judging affirmative, the fuel residual quantity based on the output of a fuel quantity sensor 21 is compared with the specified limit value, and when the fuel is sufficient, normal operation is continued. When the fuel residual quantity is less than the limit value, an air-fuel ratio feedback control factor is changed, and the fuel injection quantity is computed in such a way as to make the air-fuel ratio at the idling time larger than that at the time of fuel being sufficient to economize fuel consumption.

Filed: 1989-04-19
Abstract: PURPOSE:To obtain the optical component which is reducible in size and uniforms luminous flux with high efficiency by setting specific orthogonal coordinate axes and specifying both surfaces forming each prism unit and the array directions of respective prism units. CONSTITUTION:A body formed by laminating both saw-tooth transparent bodies which have prism units formed on a couple of opposite surfaces or a transparent body in a similar shape is used; and one of the couple of surfaces is used as an incidence surface, and the other is used as a projection surface. When an X axis is set at right angles to both those surfaces and a Y axis is set in parallel to a Z axis, the ridges of both surfaces constituting the respective prism units are parallel to the Z axis, the array direction of the respective prism units coincides with the direction of a Y axis, and both surfaces constituting each prism unit are at an angle theta or -theta shown by an X group and expressions I and II. Here, delta is a smaller angle between the divergence angle of incident luminous flux and the divergence angle (+ or -delta) that a device which utilizes projection luminous flux can utilize and less than theta0 and (n) is the refractive index of the transparent body. This constitution can uniform the light intensity of even irregular luminous flux and a light source like this can easily be manufactured.

Title: Psa type adsorption utilizing heats of adsorption and desorption
Inventor: MORI HIDEJI
IPC: B01D53/02
Filed: 1980-07-18
Abstract: PURPOSE: To eliminate the need for a cooler for an adsorption tower and also a heater for a desorption tower by using a system in which adsorption and desorption are performed in adjacent two layers, the desorption side is heated by the heat of adsorption, and the adsorption side is cooled by the heat of adsorption.  
     CONSTITUTION: Adsorption is performed in the layer A of an adsorption tower 1 divided into two layers by a partition plate C, and desorption is performed in the layer B. Pressurized air is sent through a duct 11 and a valve 21 into the layer A, adsorbates, e.g., moisture, etc., are removed, and then the air is sent as a product air to the outside through a valve 23 and a duct 12. On the other hand, clean gas is sent through a duct 13 and a valve 26 into the layer B under reduced pressure, and adsorbates are removed from an adsorbent and then discharged through a valve 28 and a duct 14. The heat of adsorption generated in the layer A is utilized as the heat of desorption for the layer B through the partition plate C in such a way as to neutralize a change in temperature between the layers A and B. Thus, the temperature rise of the layer A is smaller, its adsorption capacity is greater, and the falling of temperature in the layer B is smaller, thereby raising its desorption capability.
