To provide a data imprinting device for a camera which has a simple construction and does not make the main body of the camera large in size, a data imprinting device for a camera includes: an LED for optically generating data to be imprinted on a film surface; a prism for allowing data light generated by the LED to form an image on the film surface; a holder for holding the LED and the prism and disposed in such a manner as to be movable in a direction perpendicular to an optical axis for photographing of the camera; and data-imprinting-position changing means for moving the holder in interlocked relation with a changeover of a photographing image size on the film surface, and for changing a position of imprinting data on the film surface.

A pole device for a skiing contest comprises a cylindrical member to be embedded in a snow ground, a pole base member to be fitted into the cylindrical member and a pole portion fitted into the pole base member. The pole base member is formed with grooves extending in an axial direction thereof on an outer peripheral surface thereof and the cylindrical member is formed with projections at an inner peripheral surface thereof. Each of the projections has an outer shape to be fitted in the groove. The groove is composed of a first guide groove having an end portion through which the projection enters the groove, a second guide groove formed to be continuous to the first guide groove through a circumferintially shifted groove portion and a circumferential fitting groove formed at a portion near upper end of the pole base member to be continuous to the second guide groove. A pair of grooves are formed on the outer peripheral surface of the pole base member in an axial symmetrical arrangement and a pair of projections are formed on the inner peripheral surface of the cylindrical member in an axial symmetrical arrangement. A triangular guide piece is formed to an edge portion of each of the circumferentially shifted groove portions so as to project inward thereof.

A ceramic-metal joined composite body including a ceramic member having a projection formed thereon, and a metallic member having a recess formed therein. The projection of the ceramic member is fitted into the recess of the metallic member, and a corner of a bottom of the recess has a rounded dimension such that R/D.gtoreq.0.04, in which R and D are the rounded dimension of the corner of the bottom of the recess and an outer diameter of the projection, respectively. The ceramic-metal joined composite body particularly is useful in a rotary shaft for a turbocharger rotor or a gas turbine rotor.

An automatic transmission shift control device which prevents shifting from the "Park" position to any other position unless the ignition key is at the "on" position and the brake pedal is fully depressed. A safety feature is incorporated so as to insure against accidental gear shifting. To shift the control from the "Park" position a control button located on the shift handle is manually pressed. The control button mechanically depresses a linkage rod which in turn moves the shift position pin out of its "Park" locking position. However, the linkage rod cannot move downward unless a bushing which has clearance slots for the position pin is rotated by a solenoid, which is acuated only when the ignition is "on" and the brake pedal is pressed. Also, the bushing surface in proximity to the bushing slots is shaped so as to prevent accidental engagement of the positioning pins.

The present invention provides a cyanoguanidine derivtive which is a precursor for the synthesis of N-cyano-N'-methyl-N"-[2-{(5-methyl-1H-imidazol-4-yl)methylothio}ethyl]-guanidine (Cimetidine) or its relted compound, which has an action of controlling secretion of acid in the stomach based on the histamine H.sub.2 receptor antagonism and is valuable as a drug for treating gastric ulcer. This cyanoguanidine derivative is prepared by reacting a haloketone derivative with an ammonium salt and a lower fatty acid salt or by reacting other cyanoguanidine derivative with an ammonium salt.

In order to provide a phosphor for a low-voltage electron beam and a vacuum fluorescent display apparatus in which the phosphor is used, a deposition layer is formed on a surface of a main body of a phosphor shown by the following chemical formula (1), the deposition layer being a plurality of oxide layers sequentially deposited on the surface of the phosphor main body. The phosphor for a low-voltage electron beam contains no cadmium, but has exceptional high-temperature exposure characteristics, as well as prolonged service life and higher brightness.
