Title: Equipment and method for making snowflake
Inventor: SUZUKI TOSHIYASU
IPC: F25C3/04
Filed: 1994-12-27
Abstract: PURPOSE: To make snowflakes artificially by providing a liquefied gas-blowing means which blows a liquefied gas into a snow making chamber, freezes atomized water blown in by a two-fluid blowing means, so that it be made snow, and disperses the snow thus made into the air from an opening. CONSTITUTION: When water to be an element of snow is blown, together with compressed air, into a snow making chamber 1 from a two-fluid spray nozzle 2, the water blown in is atomized when it comes out from the two-fluid spray nozzle 2, and floats in a space inside the snow making chamber 1, forming a swirling flow 6. When a liquefied gas is blown against this atomized water by a liquefied gas blowing nozzle 3, the atomized water is frozen in a moment and becomes snowflakes (flake-shaped ice pieces). Accordingly, these can be used for an attraction or others.

Title: Cartridge loading device, and recording and reproducing device
Inventor: NAKAJIMA YOSHINOBU
IPC: G11B15/675
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To suppress the increase in the number of components and the complexity of the structure and to eject a tape cartridge from a device through manual operation. SOLUTION: When an ejecting depression member 230 is moved back with a tool 264, a depressing force acts on an ejecting drive member 248 through the ejecting depression member 230. This depressing force generates a driving force for moving the ejecting drive member 248 backward and moment for swinging the ejecting drive member 248 counterclockwise. Consequently, the ejecting drive member 248 swings from a disengagement position to an engagement position to engage a rack part 260 with the tooth part 95 of a cam gear 94 and when the swing is limited by the cam gear 94, the member moves along the pitch line of the rack part 260. Consequently, the cam gear 94 rotates counterclockwise and a carrier loaded with a tape cartridge 12 is moved to a loading/unloading position side.
