  • Publication number: 20020124563
    Abstract: A master cylinder of the invention supplies a brake fluid from a large diameter pressurizing chamber 56 to a small diameter hydraulic chamber 49 by opening a reverse flow checking opening and closing portion 61 by sliding movement of a stepped piston 16 forwardly, that is, fast fill and when the hydraulic pressure of the large diameter pressurizing chamber 56 rises, a control valve 86 escapes the hydraulic pressure of the large diameter pressurizing chamber 56 to a reservoir 12 to gradually lower in accordance with rise of the hydraulic pressure of the small diameter hydraulic chamber 49, thereby capable of reducing a strange feeling in a pedal feeling caused by sudden pressure release of the large diameter pressuring chamber 56.

  • Patent number: 6438471
    Abstract: The present invention provides a system for performing procedures to request repair, without troubling the driver, when a car breaks down, as well as various onboard peripheral apparatuses and cellular phone used for this system. This system comprises an onboard peripheral apparatus having a failure detector, an onboard main controller for managing car information, a cellular phone which can make wireless connection to the onboard main controller, and a response center for receiving requests for car repairs and maintenance and making arrangements therefor. When a failure is detected, repair request is transmitted to the response center through wireless communication together with the user ID of the driver. Based on this request, the response center acquires remedy information from a car manufacturer and makes arrangements for repair and provides this remedy information to a repair shop.

  • Patent number: 6373799
    Abstract: An optical recording disk intended only for the reproduction of a main information and used by a information management system has the attachment of a memory in which data for the management of the main information is written and read out easily and reliably. The memory has associated electromagnetic coupling means for transacting the record management data with and receiving power from a recording/reproduction apparatus. The electromagnetic coupling means is built in the memory or disposed in an annular or spiral form on the disk. The transmission frequency band for data transaction and power supply is set outside the main information reproduction frequency band. The memory is disposed in or on an appropriate plastic layer of the disk depending on the usage of the disk, and located in the inner or outer section of the recording medium forming area on the disk depending on the transmission band. This low-cost optical disk can be manufactured at a high reliability and high yield.

  • Publication number: 20010020677
    Abstract: An invisible symbol reading apparatus includes a heating unit for heating an invisible symbol formed on a sample and containing a material which emits infrared light when heated, a detecting unit for detecting infrared light emitted from the invisible symbol, and an arithmetic operation unit for binarizing a detection signal from the detecting unit. The arithmetic operation unit calculates a differential coefficient of the detection signal, that corresponds to a position on the sample. On the basis of upper and lower threshold values set for the differential coefficient, the arithmetic operation unit determines a maximum value of the differential coefficient in a region exceeding the upper threshold value and a minimum value of the differential coefficient in a region smaller than the lower threshold value. The arithmetic operation unit binarizes the detection signal by using the maximum or minimum value as a leading or trailing edge of a binary function.
