The present disclosure relates to a device for activating thermochromatic ink. The device may include a drawing tip, a heating element, which may include a positive temperature coefficient (PTC) heating element, communicably coupled to the drawing tip and configure to heat the drawing tip, and a power source configured to provide power to the heating element. The power source may be a lithium-ion battery. The battery may be rechargeable, and the device may have a charging port to recharge the battery from a power source coupled to the charging port. The device may have a regulator for regulating power from the power source to the heating element. The device may have a controller for directing power from the power source to the heating element. Further the heating element may be configured to heat the drawing tip to a temperature between 30-70 degrees Celsius.

A balloon apparatus includes a balloon having an inflation opening that can be closed for keeping the balloon inflated. The apparatus also includes a light source inside the balloon, wiring connecting a power source to the light source, and a tube through which the wiring extends. The tube may be entirely enclosed in the balloon. This balloon can be inexpensive to fabricate and can provide an attractive advertising medium.

The invention concerns an optical device for producing a visual illusion by holding a mirror under one's eyes. More particularly, it concerns a device for fixing on a user's head a horizontal support comprising a mirror and located just below his eyes. It consists of a support (1) whereon is fixed a mirror (2). Two perpendicular stop elements (3a and 3b), resting on the user's cheeks enable to maintain the horizontal support (1). Two linking branches (4a and 4b) with fixing straps (5a and 5b) are attached with the fixing straps to the branches (4a and 4b) so as to press one against the other above the user's head, thereby enabling to adjust the height of the device. Two fixing straps (6a and 6b) are attached to the branches (4a and 4b) to press one against the other behind the user's head so as to maintain the whole device pressed against his face.

A toy (564) that includes a first electrode (552) and a second electrode (554) that are coupled to an electrical circuit. The first electrode is also coupled to a consumable substance (558). The circuit is closed when an end user becomes electrically coupled to the first electrode and the consumable substance. Closing the circuit may activate one or more actuators, sound devices, etc. of the toy.

The present invention relates to luminescent playthings such as candles, table lights, pen lights, illumination, illuminating playthings for camp, illuminating playthings for night fishing, fish-gathering lamps, safety candles, neon lights, luminescent inks, luminescent pens, luminescent coatings or luminescent writing implements, in which a soft light of an indescribable tone of color not obtainable from flames of conventional candles is emitted via seawater, lake and marsh water, river water, ground water, tap water or mineral drinking water by utilizing 3 components of luciferin, luciferase and ATP or 4 components of these components plus a metal salt, out of components necessary for bioluminescence in fireflies.
摘要:
The present invention refers to a method of producing drawings, which should be observed through a technique called "virtual approximation". The developed method consists in making a drawing in two horizontally aligned parts, separated from each other by a clearance of about 5 cm, said parts being juxtaposed to each other so as to form the desired drawing, when observed with the focus of the eyes displaced "backwards" of the surface on which they are drawn.

A method for energizing an energization-operated toy element in which an electric double layer capacitor is employed as energization means for energizing a toy element which is operated upon application of low voltage, the capacitor is charged upon reception of a current from a DC power source, and the charged electric power is used to energize a toy load as a discharge current to operate the toy element. An energization-operated toy which comprises an energization heating color changing element provided with an energization resistant heating member for generating heat upon application of the DC voltage and a thermal color changing layer disposed in contact with or close to the heating member, energization means consisting of an electric double layer capacitor for generating heat by supplying the discharge current to the energization resistant heating member, and a power source for supplying the DC voltage from 0.5 V to 9.0 V to the capacitor.
摘要:
A peep show toy and a peep show toy kit which are simple in construction, suitable for individual use, and capable of exhibiting a landscape, portrait, history picture or narrative are disclosed, which include a hollow cube (10) formed by at least one planar or curved wall (11 to 16). At least one observation hole (21) through which an observer can peep into the hollow cube (10) is provided in at least one place of the hollow cube (10). In an area of the inner surface of the aforesaid at least one wall (11 to 16) which comes in sight through the aforesaid at least one observation hole (21), a picture is drawn in perspective with a visual point disposed at the observation hole (21).
