Patent number: 5654789Abstract: The present invention relates to an optical camera having a zoom function in which a focal length can be varied or the variation is actuated by a focal length changing member, and in particular to a camera in which a focal length is varied through a motor.The optical camera has a zoom lens operable by a rotatable zoom ring for changing the focal length thereof. An automatic focusing operation is effected by a control means when the focal length is changed so that an image of an object viewed through a viewfinder remains in focus. The zoom lens can include a motor and an in-exposure zoom control means can be provided for controlling zooming movement of the lens during an exposure operation.Type: GrantFiled: March 30, 1995Date of Patent: August 5, 1997Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Tadayuki Kirigaya, Hiroyuki Takahashi, Masahiro Nakata, Hideaki Tsuji, Tetsuo Hosokawa

Patent number: 4835546Abstract: An improved electronic data recorder for use in a vehicle includes a housing having a pair of connectors. The housing encloses a modular converter, a printer module, a continuous roll of paper, a modular paper advance mechanism, conversion electronics, and memory and computation electronics. Also included in the housing are a driver code input keypad, a clock and date display, and keys for selecting a variety of functions. The data recorder connects to a free end of a rotatable odometer-speedometer cable between a rotating part of a vehicle to which the cable is attached and the vehicle odometer-speedometer. The data recorder also connects to the vehicle battery and ignition switch. The rotational motion of the cable is communicated into the housing of the data recorder by one of the connectors and from there into the modular converter. The converter converts the rotational motion into a plurality of unique electrical signals representative of mileage.Type: GrantFiled: July 1, 1987Date of Patent: May 30, 1989Inventor: Walter L. Keller

Patent number: 4547780Abstract: A hand-fed printer for sheet material is described which includes an electronic print head, e.g., a dot matrix wire print head, a channel for cut sheets such as a slot that is open along one edge to receive and print the sheets. Sensors are provided for placing the print head in operation when the leading edge of the paper is sensed and for regulating the printing speed. An electronic data processor is connected to the print head to print letters and numbers on the sheet.Type: GrantFiled: September 17, 1984Date of Patent: October 15, 1985Assignee: Fargo Electronic Services Inc.Inventor: Robert P. Cummins

Patent number: 4205323Abstract: The resolution of an image that is produced by a graphic recorder is related to the rate that recording paper passes through a recording zone and the sweep rate is related to the rate at which a scanning electrode contacts the recording paper. According to the present invention, both the sweep rate and the resolution are simultaneously coordinated through the use of a ratchet wheel and pawl that are interconnected between the scanning electrode and feed rolls. The ratchet wheel is indexed through the movement of the scanning electrode and as the scanning electrode makes a sweep, the feed rolls are indexed by successive or multiply successive teeth in the ratchet wheel. An anti-backlash device is associated with the ratchet wheel to prevent the ratchet wheel and the feed rolls from reversing themselves during operation of the recorder.Type: GrantFiled: July 31, 1978Date of Patent: May 27, 1980Assignee: Alden Research FoundationInventors: George C. Williams, Edward W. Fay

Patent number: 4160255Abstract: Battery-operated, dot type recording apparatus which is so constructed that the recording paper feed and the recording operation are alternately executed in short times and that a measuring instrument is actuated only during a period of time covering time intervals before and after each recording operation, the actuation of the measuring instrument and the recording paper feed as well as the recording operation being carried out at good timing in a short period of time, whereby the consumption of the battery is low, no high power is required at a time, and the recovery time of the battery suffices, so that the battery is of long life.Type: GrantFiled: September 19, 1977Date of Patent: July 3, 1979Assignee: Mitogiken, Ltd.Inventor: Keigo Kobayashi

Patent number: 4150385Abstract: A point recorder has a clock that periodically generates an electrical impulse that is operative through a speaker-type electromagnet to displace a printing element from a holding position wherein an indicator moveable in an indicating direction is spaced from a recording strip to an imprinting position wherein the indicator is pressed against the recording strip. A pawl carried on the printing element is engageable in teeth on a drive roll over which the recording strip is spanned so that each time the printing element moves between its two positions the recording strip is incrementally advanced. The printing element has a bar which presses a needle constituting the indicator against the paper strip where it is spanned over the drive roller so as to record as a point or dot the position of the indicator therealong.Type: GrantFiled: March 15, 1977Date of Patent: April 17, 1979Assignee: Metrawatt A.G.Inventor: Alfred Ahles, deceased

Patent number: 4032926Abstract: A data recording instrument having a recording sheet supply roll and a recording sheet take-up roll used for continuously recording a sensor. The instrument utilizes an axially movable rod activated by pulsing means. Movement of the rod advances the take-up roll through lever means connected to the axially movable rod. The lever means adjusts the degree of turning of the take-up roll in proportion to the amount of recording sheet accumulated on the take-up roll. The axial movement of the rod also activates marking means for charting the resultant output of at least one continuous sensor.Type: GrantFiled: May 12, 1976Date of Patent: June 28, 1977Inventor: George Robert Hale

Patent number: 3987667Abstract: The deflection of a subterranean tunnel is measured with a rod-like, self-contained instrument that is adapted to be inserted into a radially extending bore of the tunnel adjacent an end of the tunnel where the tunnel is being dug. One end of the instrument is anchored at the end of the bore remote from the tunnel wall, while the other end of the instrument is anchored adjacent the end of the wall in proximity to the tunnel wall. The two ends of the instrument are linearly displaceable relative to each other; the displacement is measured by a transducer means mounted on the instrument. Included in the instrument is a data storage means including a paper tape recorder periodically responsive to a parallel binary signal indicative of the measured displacement. In response to an operator command, a visual indicator including a pair of different colored light emitting diodes, at a face of the rod adjacent the tunnel wall, is responsive to a serial binary signal indicative of the measured displacement.Type: GrantFiled: June 9, 1975Date of Patent: October 26, 1976Assignee: The United States of America as represented by the Secretary of the InteriorInventors: Donald Edgar Rasmussen, Peter John Hof, Jr.

Patent number: 3949402Abstract: A thermal recorder having an analog recording stylus and a digital recording head uses a stepping drive means for intermittently driving a thermally responsive recording medium past the analog recording stylus and digital recording head. The analog recording stylus is maintained in contact with the intermittently driven recording medium which the digital recording head is mounted on one end of a pivoted support arm. A solenoid is connected to the other end of the support arm and is selectively energized to bring the digital recording head into contact with the recording medium during the interval between the stepped movements of the recording medium when the recording medium is at rest.Type: GrantFiled: February 3, 1975Date of Patent: April 6, 1976Assignee: Honeywell Inc.Inventors: Thomas P. Kelley, Charles E. Lane, III
