  • Patent number: 11044838
    Abstract: Effectively control the temperature of a control unit of a railway equipment inspecting and measuring apparatus, and install the control unit of the railway equipment inspecting and measuring on the roof of the passenger car. The first space is formed between the control unit and the heat insulating case. The second space is formed between the heat insulating case and the cover. In the first space, heat is conducted between the air in the first space and the heat exchange element by the first heat conducting member, and the first fan causes circulation of the air in the first space. In the second space, heat is conducted between the air in the second space and the heat exchange element by the second heat conducting member, and the air inside the second space is diffused by blowing the air from a suction port into the second space with the second fan.

  • Publication number: 20210032372
    Abstract: Provided is a method for producing cellulose particles or cellulose acetate particles. By a production method including: (a) dissolving cellulose acetate in an organic solvent and preparing a cellulose acetate solution; (b) obtaining an emulsion by passing the cellulose acetate solution and an aqueous medium through a gap between an outer cylinder and an inner cylinder arranged coaxially inside the outer cylinder and rotating at least one of the outer cylinder and the inner cylinder; and (c) precipitating cellulose acetate particles from the emulsion, cellulose acetate particles are produced. By further saponifying the cellulose acetate obtained by the production method, cellulose particles are produced.

  • Patent number: 8659387
    Abstract: A function for authenticating an operator to control whether to permit them to operate a vehicle (20) can be added to the vehicle by simple modification. An operation permission control device (22) is installed on the vehicle (20). The operation permission control device (22) incorporates a relay inserted in the middle of a start signal line (47) connecting a key switch (46) and vehicle start circuit (48) (starter relay of an engine-powered vehicle or main controller of a battery-powered vehicle) and can open and close the start signal line (47). The operation permission control device (22) reads data of a authentication card (34) carried by the operator, collates the read data with preprogrammed data in a removable set memory a (32). If the data match, the device connects the start signal line (47) to enable start of the vehicle.

  • Patent number: 5887088
    Abstract: A novel input device and for an information processing system for carrying out a process on the basis of input data, the input device is disclosed. In the input device, the output unit develops instructive-document form information and outputs an instructive document to which an entry is not yet made by a user. The extracting unit extracts analysis information for analyzing an instructive document to which an entry has been made by the user from the instructive-document form information. The storing unit stores the extracted analysis information. The analyzing unit analyzes the information on the received instructive document after a user makes an entry to thereto while referring to the analysis information. With such an arrangement, the input device receives the information on the instructive document having entries made thereto, and inputs information obtained by the process of analyzing the received information to the information processing system.
