  • Patent number: 11961429
    Abstract: A head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

  • Patent number: 6485642
    Abstract: A sample solution is sent into a concentration column through a three-way joint and a three-way switching valve to trap and concentrate the sample components on the concentration column, followed by injecting the sample solution into an injector by operating a first dilution solvent pump. When a large volume of the sample solution is to be sent or when the sample solution has a high solvent strength, trapping and concentration on the concentration column may be facilitated by replacing the sample solvent with a second dilution solvent by allowing the second dilution solvent to flow into the three-way joint after setting the flow rate of the second dilution solvent from a second dilution solvent vessel to a prescribed flow rate using a second dilution solvent pump.

  • Patent number: 5377326
    Abstract: A small electronic apparatus such as an electronic organizer, electronic memo, etc. is disclosed which has a memory for storing data, and a communication unit for transmitting data stored in the memory to another electronic apparatus, and for receiving data from the other electronic apparatus. The apparatus selects, before transmitting at least one portion of said data, either of an add mode (transmitted data is added to data stored in the other electronic apparatus) and a update mode (data stored in the other electronic apparatus is replaced with the transmitted data). The apparatus has a signal unit for, when the add mode is selected, transmitting a first signal indicative that the add mode is selected to the other electronic apparatus, and for, when the update mode is selected, transmitting a second signal indicative that the update mode is selected to the other electronic apparatus. The apparatus displays data which has been transmitted when a data transmission error has occurred.

  • Patent number: 5150293
    Abstract: An improved electronic apparatus such as a so-called electronic memo or data book is disclosed. In the apparatus, a numeric string such as a telephone number can be stored together with two kinds of character strings such as a person name and a company name. The apparatus has a memory for storing a portion of data displayed on a display, and the portion of data can used as a search key in the subsequent search operation. The apparatus allows a user to easily utilize the called results of either a sequential search or a direct search in a subsequent direct search and to change the mode to a sequential search at any desired point during execution of a direct search.
