A hollow box-shaped mover or a needle is moved, without using a power transmission mechanism midway, to a portion according to a measured value of a graduation portion, by housing the mover between a dial and a surrounding facing and in a guide groove portion formed along a graduation portion, in a manner to move along the guide groove portion, by attaching a needle to the mover, and by moving the mover along the guide groove portion by a linear motor unit, which is constituted to have a multipo...

The present invention relates to a meter, especially a meter for metering aerosol devices, basically consisting of four disk units that are arranged in a parallel position and located on the same axis.

A meter for use in a multi-speed vehicle for indicating both the rotating speed of the engine and the running speed of the vehicle by a single pointer. The meter comprises a character drum of polygonal cross section, and speed scales corresponding to individual gear positions of the multi-speed vehicle are provided on the different side faces of this character drum. This character drum is suitably rotated to expose the desired one only of the speed scales in a display window formed in the dial o...

A device for delivering anhydrous ammonia to the soil so as to provide substantially uniform treatment of the soil which comprises a conduit or delivery pipe connected to a supply of anhydrous liquid ammonia through a valve which is opened for a set pre-determined period of time by a time switch. Means are provided for actuating the time switch at times spaced in proportion to the rate of movement of the apparatus over the soil.

A lens meter having a projection system (5) provided with a projection light source (7) adapted to project a measuring beam onto a lens (14) to be examined, and a light receiving system (6) provided with a light receiving element (15) adapted to receive the measuring beam which has passed through the test lens (14), the optical characteristics of the test lens (14) being determined on the basis of a position in which the light receiving element (15) receives the measuring beam which has passed t...

A multiple pipeline orientation water meter that includes a water meter arrangement having a water meter and a pipe connector. The water meter body coacts with the pipe connector to permit proper installation of the water meter in various piping orientations.

Accordingly, the object of the present invention is to provide a pulse meter comprising a pen body installed with a counting microprocessor, and a liquid crystal display (LCD) and a counter are installed on the proper position of the pen body. The counting microprocessor is connected with the LCD and the counting key. One hand may press a tested person or a patient for sensing the beat of the pulse thereof, and the other hand serves to press a counting key to count the times of the pulse, and th...

The present invention is to provide a combination meter having a close arrangement of a plurality of drive axles of pointers so as to save a space thereof and provide a good design thereof. The combination meter includes a speedometer and a tachometer. A speedometer dial and a tachometer dial are disposed on the circumference of one circle. The pointers each include a deadweight holder to hold a deadweight. The deadweight holders are separately overlapped each other in directions of the drive ax...

Potential leakage points are avoided, mishandling or loss of loose, unattached parts minimized and installation in tight places facilitated by a meter bar of elongated cast metal structure having a central bar, an outlet conduit section and an inlet conduit section, both integral with the meter bar. The inlet and outlet sections may include integral tail pieces and an upstream end of the inlet section includes an elongated, downwardly curved conduit to eliminate the need for the use of elbows, p...

A lens meter for measuring optical characteristics of a lens to be measured includes a measurement optical system including a light source which projects a measurement light beam to the lens and a light receiving sensor which receives the measurement light beam having passed through the lens; an arithmetic part which obtains optical characteristic distribution of a predetermined measurement region of the lens based on a light reception result of the light receiving sensor; near-vision-portion de...
