Abstract: A computer mouse is provided which includes an elastic cover detachably secured upon a main body of the mouse, to enhance ease of operation and reduce muscle strain and soreness by repeatedly operating the computer mouse. The main body has left and right click knobs and optionally a scrolling wheel, pivotally mounted thereon. The cover and main body can be complementary coupled together through respective mating convex and concave portions. A display surface is explicitly provided on the main body and/or cover to allow for labeling of instructional information and/or advertising. Additionally, the computer mouse, notably the detachably mounted cover member, can be provided in an attractive shape to encourage use by a child.

Abstract: A clock with an insertion part is provided to facilitate presenting various illustrations such as photographs, advertising copy, logos, etc., upon the front surface thereof after purchase by a customer. The insertion part is separately provided apart from the clock and then inserted into and coupled to the main clock frame from the rear after assembly of the clock. In a preferred embodiment, the clock includes the main body frame, an hour plate, a transparent case and a backside case, with the part being inserted into the insertion opening provided in the backside case.

Abstract: A device for magnetically adhering to an external surface includes one or more magnets placed in a storage chamber. The magnet(s) always remain oriented to adhere to the external surface in any position of the device.

Abstract: Conventionally, a dual cup is known which provides an air thermal insulating layer between a metal inner container and outer container. Since the dual cup totally comprises double layers, it can not be heated with an electric heater. In addition, manufacturing of the dual cup is costly. Therefore, a dual cup of the present invention is provided which comprises a bottom portion being one layer to improve heat absorption even with an electric heater by a weak power from a dry battery or a USB hub of personal computer, and which comprises a side portion being in two layer structure for defining an air thermal insulating layer by hermetically sealing air to improve heat retaining effect.

Abstract: An improved magnetic device is provided for adhering to an outer magnetic or magnetizable surface in a secure, reliable manner, by ensuring proper orientation of a magnet contained therein at all times.

Abstract: The present invention is directed to a portable electric light such as a flashlight having a main stem or shaft for containing at least one battery or dry cell for operating an electric light bulb mounted upon one end of the stem or shaft, and a cover removably secured to the main stem or shaft cover and protect the electric light bulb. A separate outer concentric member at least partially formed of transparent material is removably inserted about the main stem or shaft such that labeling, indicia or images upon an outer surface of the main stem or shaft are clearly visible through the outer concentric member.

Abstract: The present invention discloses an improved paper holder for holding paper or the like in a bundle in operating a word processor, a typewriter or a computer.

Abstract: The present invention discloses a timer capable of sounding a prescribed time and further capable of functioning as a calendar, a watch or a thermometer frequently used every day life by a simple method.A hollow main body (1) is constituted by a plurality of square or rectangular side plates (3) with the same pattern connected to each other so as to form a polygonal cube frame and lids (4, 4a, 4b) having a configuration corresponding to that of the upper and lower openings of the polygonal cube frame. A pair of ON-contacts (5, 5) each in the shape of a stick are mounted at each inner surface of a time setting device (2) containing a spherical conductor (6) displaced within the frame with a reduced and almost the same pattern a that of the frame along with a connecting portion of a side plate (7). Thus, the timer is constituted in a manner such that the side plate (7) of the frame and time setting device are parallel each other.

Abstract: A hollow main body(1) is constituted by a plurality of square or rectangular side plates(3) with the same pattern connected to each other so as to form a polygonal cube frame and lids(4,4a,4b) having a configuration corresponding to that of the upper and lower openings of said polygonal cube frame. Two ON-contacts(5,5) in the shape of a stick are mounted at each inner surface of a time setting device(2) containing a spherical conductor(6) displaced within the frame with the reduced and almost the same pattern with that of said frame along with a connecting portion (8). Thus, the timer is constituted in a manner that the side plates of said frame and time setting device are parallel each other. A preliminarily prescribed setting time(9) is indicated on the outer surface of said hollow main body(1).
