  • Publication number: 20220024717
    Abstract: In the present invention, a process of receiving an image obtained by capturing a measurement target place with a camera, calculating a number of people in the measurement target place based on the image received, and allocating a car according to the calculated number of people is performed. Here, when an abnormality that an image from the camera cannot be received is determined, a process of referring to a detection value of a sensor or the like installed in a car or in the measurement target place to calculate the number of people in the car or the measurement target place is performed.

  • Publication number: 20180015246
    Abstract: A speaking valve which is applied to a respiration opening of a tracheostomy tube comprises: a main body portion which has a passage portion communicating with the respiration opening; a balloon which makes a motion between an opened state for opening the passage portion of the main body portion and a closed state for closing the passage portion; a syringe which is provided away from the main body portion and accepts a pushing operation to a plunger by a patient; and a coupling tube which couples the syringe and the balloon with each other and makes the balloon in a shrink state transform to a bloat state by the operation to the syringe, so that the motion from the opened state to the closed state is made.

  • Patent number: 7906732
    Abstract: Provided is a process for producing a glass plate with a conductive printed wire, which does not require a screen plate for each model, facilitates adjustments for desired heat generation performance or antenna performance, has an excellent adhesion to a glass plate surface, and minimizes surface roughness. The process for producing a glass plate with a conductive printed wire is characterized in that a laminate comprising a layer obtained by electro printing a first conductive toner having a number standard average particle size (D50) of 10 ?m<D50?50 ?m and a layer obtained by electro printing a second conductive toner having a particle size (D50) of 5 ?m?D50?10 ?m is formed on a surface of a glass plate and the glass plate is heated to fire the toners to thereby form a conductive printed wire having a predetermined pattern on the surface of the glass plate.

  • Publication number: 20090169279
    Abstract: An electrographic printing apparatus and an electrographic printing method that prevent base fogging and maintain high quality are provided. The provided electrographic printing apparatus includes a OPC photoreceptor to which a developing device adheres charged toner to an image region of an electrostatic latent image formed on a moving surface; and a non-image-region toner removing device disposed downstream of the developing device in a moving direction of the surface of the OPC photoreceptor and at a position opposing the OPC photoreceptor, wherein the non-image-region toner removing device includes a removing roller that moves close to the OPC photoreceptor and attracts and delivers a carrier by a magnetic force, and a predetermined electric potential is applied to generate an electric field from a non-image region of the electrostatic latent image to the removing roller.

  • Patent number: 5943536
    Abstract: An electric field applying device is disposed in a position opposite to a surface of rotary developing device within an area defined between the surface of the developing means and a position of scratching device after the surface of the developing device passes through a developing area so as to apply an electric field in a direction in which ions having the polarity opposite to that of toner particles are separated from the surface of the developing device.

  • Patent number: 5835826
    Abstract: An image forming apparatus and method in which the flow of a toner image formed on an image carrier is prevented at the time of removing a surplus liquid developer and at the time of transfer of the image onto a transfer material. The apparatus includes an image carrier, a device for forming an electrostatic latent image on a surface of the image carrier, and a developing section for supplying a liquid developer onto the electrostatic latent image so as to form a toner image. The apparatus also includes a device for removing a surplus liquid developer remaining on the surface of the image carrier after the toner image is formed. A transfer device transfers the toner image onto a surface of a transfer material. An electric charge giving device, which is disposed between the developing section and the device for removing the surplus liquid developer, applies an electric charge to the toner image in a same polarity as that of the toner image.
