  • Patent number: 10317202
    Abstract: A parameter setting method of a measuring instrument includes: reading model information, measurement-related setting items, and parameters corresponding to the setting items, which are stored in the measuring instrument, and temporarily storing the read data in a storage unit of a computer; displaying an appearance image of the measuring instrument corresponding to the model information on the screen and displaying icons for selecting an operation on the screen at predetermined positions of the appearance image on the screen in correlation with each other; displaying the setting item, which is able to be selected by an operation in the measuring instrument relevant to the predetermined position corresponding to the selected icon, on the screen when selection of the icon is received; receiving changing of the parameter corresponding to the setting item using the computer; and transmitting the changed parameter from the computer to the measuring instrument.

  • Patent number: 9798445
    Abstract: A measuring instrument includes a main body casing, a detector on the main body casing and detecting an amount of stylus head displacement, a display on an outer surface of the casing; a plurality of key switches on the outer surface, a menu proximate the display on the outer surface, and a display controller controlling the display. The display includes a main display and a cursor display, which is arranged in a location alongside the menu and displays a cursor pointing to the menu, and performs control such that a measured value based on an amount of displacement is displayed, but the cursor is not displayed when in a measurement mode where the detector detects the amount of displacement, and such that a cursor is displayed so as to point to the menu corresponding to a selected menu when in a settings mode where measurement conditions are set.

  • Patent number: 9121682
    Abstract: A measuring instrument includes a display that displays measurements. The display is provided by an organic electroluminescent display device or an electronic paper including an assembly of organic EL (Electro-Luminescence) devices. Since the display is provided by the organic electroluminescent display device or an electronic paper including an assembly of organic electroluminescence devices, visibility of the display can be enhanced. Further, since the display can be used for various measuring instruments in common and the display design can be easily changed, production cost can be reduced.

  • Patent number: 7578072
    Abstract: A digital indicator (1) includes: a main body (10); a spindle (11) being axially slidable and having a contact portion (12) on one end, the contact portion abutting a to-be-measured portion; a detector (13) that detects an absolute displacement amount of the spindle (11) relative to the main body (10); and a display (14) that digitally displays the displacement amount of the spindle (11) relative to the main body (10) detected by the detector 13. The spindle (11) is slidable in a direction away from the contact portion (12) beyond the detectable range of the detector (13).

  • Patent number: 7100298
    Abstract: A contact block (31) is provided with a flat face portion (311A) parallel with the axis of a spindle (12) and a conical face portion (311B) that comes closer to the flat face portion (311A) along the axial direction of the spindle (12) in the direction of going away from the spindle (12). Even in the case of a shape formed by integrating a step and a gap inseparably, since the flat face portion (311A) is parallel with the axis of the spindle (12), it is possible to insert the contact block (31) into the gap while the axis of the spindle (12) is kept perpendicular to the direction of the gap, hence it is possible to measure the gap W accordingly.

  • Patent number: 5175695
    Abstract: An ultrasonic measuring apparatus comprising a master unit and a slave unit each having a respective transmitter circuit for transmitting towards the other unit a burst of ultrasound and each having a respective receiver circuit to detect the burst of ultrasound transmitted by the other unit. The slave unit is responsive to the detection of a burst transmitted by the master unit to transmit a return burst back to the master unit. The master unit includes control means for disabling its receiver circuit during transmission of the said burst to the slave unit and thereafter until the end of a first period of time which is sufficiently long to permit all echoes from the said burst to decay to a level where the master unit receiver circuit is not sensitive enough to detect them.
