  • Patent number: 8706367
    Abstract: A control apparatus for an internal combustion engine stores priorities preset for a plurality of external loads on the internal combustion engine and actuates the plurality of external loads in order of priority at time intervals when requests for actuation of the external loads are simultaneously made during idling of the internal combustion engine. The plurality of external loads are properly actuated, thus preventing possible engine stall.

  • Patent number: 8667834
    Abstract: An abnormality detection apparatus for a Rankine cycle system includes: a main body that vaporizes a cooling medium that circulates in an internal combustion engine by giving waste heat to the cooling medium; a gas-liquid separator that separates the cooling medium into a gas-phase and a liquid-phase; a superheater that gives waste heat of the engine to the cooling medium; a condensate header tank that stores the liquid-phase cooling medium; a vane pump that pumps the liquid-phase cooling medium. If abnormality of a cooling medium supply portion that supplies the cooling medium to the engine is not detected, the abnormality detection apparatus determines whether a vane pump has abnormality on the basis of the amount of the liquid-phase cooling medium in the gas-liquid separator, the temperature of the gas-phase cooling medium in the superheater and the amount of the liquid-phase cooling medium in the condensate header tank.

  • Patent number: 6816312
    Abstract: A lenticular lens sheet having (1) a light-transmitting lens sheet body with a lenticular lens group formed of multiple lenticular lenses placed on a surface of the body and a silver salt emulsion light-shielding layer laminated to the other surface of the light-transmitting lens sheet body. Light-transmitting areas in the light-shielding layer correspond to light-converging parts of the lenticular lenses on the body. The positions of the light-shielding areas correspond to non-light-converging parts of the lenticular lenses. The light-shielding characteristics result from the darkened silver dispersed in the silver salt emulsion. A method for making the lenticular lens sheet is disclosed also.

  • Publication number: 20040133587
    Abstract: When implementing a customer portal sit in a CRM system, fine service meeting respective customers can be provided, and labor required for creation and operation of the portal site is saved. Contents are managed in three classes: common contents for unspecific customers, default contents serving as defaults, and personal contents for specific customers. When creating default contents from the common contents, the default contents are created on the basis of a customer profile, a profile of a sales task member, and related information of other customers. The default contents are further processed with due regard to data of an individual customer to obtain personal contents. And the personal contents are used as data for display in the portal site of the customer.

  • Publication number: 20040070837
    Abstract: A lens sheet body 2 is prepared by laminating, to a transparent film 6, a lenticular lens layer 7 having a plurality of lenticular lenses arranged, and a silver salt emulsion layer 10 is laminated to this lens sheet body 2 on its light-emerging surface side. For example, lamination of the silver salt emulsion layer 10 to the lens sheet body 2 is conducted by backing a silver salt emulsion layer 10 with a transparent film 8 to obtain a silver salt photosensitive film 5 and adhering this silver salt photosensitive film 5 to the lens sheet body 2 with the use of an adhesive agent layer 9, with the transparent film 8 of the silver salt photosensitive film 5 facing the lens sheet body 2. Next, parallel rays 40 are applied to the lens sheet body 2 from the lenticular lens layer 7 side to expose those parts of the silver salt emulsion layer 10 that correspond to the light-converging parts of the lenticular lenses 3a. Thereafter, the silver salt emulsion layer 10 exposed is developed.

  • Patent number: 6371076
    Abstract: An engine performs a combustion mode selected from a plurality of combustion modes. The combustion modes include stratified-charge combustion and homogeneous-charge combustion. A electronic control unit switches the combustion mode in accordance with the current running conditions of the engine. The electronic control unit limits a running area in which stratified-charge combustion is performed in accordance with the frequency of engine knocking occurrences. This properly executes knocking control without adversely affecting the execution of is stratified-charge combustion.
