In order that data indicating the allocation of ports for controlling light-emitting devices or the start year and the end year of a calendar can be arbitrarily rewritten, an imprinting control unit includes a calendar control unit for calculating the time and date, an imprinting output control unit for outputting imprinting patterns to an imprinting unit in order to perform data recording, and a memory. The calendar start year and end year data and the imprinting output patterns stored in the memory can be rewritten into arbitrary data through a communication line. This allows easy changes in the wiring to the imprinting unit and in the calendar specifications.

A circuit breaker-includes: a casing having a base and a main cover secured to the base, the casing accommodating a circuit breaking mechanism; a recesses formed in one surface of the main cover, the opposite surface of which is on the side of the base, the recess being adapted to receive an auxiliary device of the circuit breaking mechanism; and an auxiliary cover mounted on the main cover in such a manner as to close the recess. The circuit breaker is automatically tripped when the auxiliary cover is opened, thus permitting installation of the auxiliary device thereon with high security.

A color image forming method by superimposing plural kinds of toner with different colors on a surface of a photoreceptor body is disclosed. The surface of the photoreceptor is uniformly pre-charged with electricity. A kind of toner is selected according to a predetermined order. A latent image corresponding to the selected toner, and consequently corresponding to a selected color, is formed on the surface by a photo-electric exposure. A toner image is formed by developing the latent image with the selected toner. A multiple color image is formed by repeating the above two steps with regard to succeeding colors and kinds of toners until all kinds of toner having been developed. In repeating the development, the following formulas are satisfied under the supposition that (Q/M)n is an amount of electrification of toner used in the n-th development.1.1=

In a circuit breaker of double break type, a first moving contact arm and a second moving contact arm are pivoted on a common pin shaft in a manner to move mechanically independent from each other and are electrically connected at the parts near the pivoted ends by a flexible conductor, such as a braided wires, and thereby stable and reliable contacts of the moving contacts on the stationary contacts are assured.

A compact cash register comprises a first member for freely adjusting the visual angle of the same. The first member is connected to a second member of a casing of the compact cash register so as to provide in order to adjust the visual angle of the cash register. The first member comprises a ball biased continuously by a spring. The second member includes a cavity formed on the surface of a cover of the casing. The connection between the first member and the second member allows the compact cash register to be supported obliquely. The connection may be formed as a ratchet mechanism, a pivotal mechanism and the like. The casing comprises at least two compartments each containing the compact cash register and cash, the two compartments being adjacent to each other.

A water jet propulsion system for use with boats having an impeller duct which discharges a stream of liquid through a nozzle to propel the vessel in a forward direction. A reversal plate is provided which occludes the rearward jet opening and causes the stream to exit through a pair of reverse movement ports, one disposed on each side of the nozzle to direct the water jet from the impeller duct forwardly and preferably also slanted downwardly when the boat is to be reversed.
