Title: Step for escalator
Inventor: GERUHARUTO RUNARUDEI
IPC: B66B23/12
Filed: 1985-08-21
Abstract: In escalators or moving stairways there exists, between the moving step and the fixedly positioned skirt guard, a latent risk of entrapment or catching of the shoe of the passenger, especially when wearing light footwear. The inventive warning devices are arranged at the side uprights or plates of the step of the escalator and induce the user or passenger, by means of a physically and, possibly additionally, by means of an acoustically perceptible signal, to leave the stepped-on danger zone. Each of the warning devices comprising, for example, two swivelingly or pivotably mounted segments is held in a projecting readiness position, through the force of a spring, in relation to the tread surface and the front surface of the step. When the warning device is stepped upon by the passenger, this warning device is pressed into a flush position with respect to the tread surface of the step and in which position a pin, positioned on one of the segments, is pressed against a profiled guide edge of the related skirt guard. The pin thus glides over the profiled guide edge, during the movement of the step, and causes the step to vibrate. Depending upon the shape of the profiling of the guide edge, an additional acoustically perceptible sound or clatter can be generated.

Title: Thin film of single/crystal epitaxial diamond pure as isotope and method of production thereof
Inventor: UIRIAMU FURANKU BANHORUZAA
IPC: C30B29/04
Filed: 1991-06-28
Abstract: The present invention is directed to the production of single-crystal diamond consisting of isotopically pure carbon-12 or carbon-13. The product is believed to be like that diamond product in application Serial No. 448,469, but is made by a different method. In the present invention, isotopically pure single-crystal diamond is grown on a single crystal substrate directly from isotopically pure carbon-12 or carbon-13. One method for forming isotopically pure single-crystal diamond comprises the steps of placing in a reaction chamber a single crystal substrate heated to an elevated CVD diamond-forming temperature. A gaseous mixture of hydrogen and a hydrocarbon of isotopically pure carbon-12 or carbon-13 is provided in the chamber. The gaseous mixture then is at least partially decomposed in the chamber to form an isotopically-pure single crystal diamond layer on the single crystal substrate disposed therein. The thus-formed isotopically-pure single crystal diamond layer optionally may be removed from the single crystal substrate. Another method for forming isotopically-pure single-crystal diamond comprises diffusing isotopically-pure carbon-12 or carbon-13 through a metallic catalyst/solvent under high pressure to a region containing a single crystal substrate to form an isotopically-pure single-crystal diamond layer on said single crystal substrate. The single crystal substrate is stable under the high pressure and elevated temperatures used during the diffusion process. The single crystal substrates optionally may be diamond, including the isotopically-pure single-crystal diamond films formed by the inventive method disclosed herein, thus forming multi-layered diamond structures.

Title: Liquid crystal projector
Inventor: HAYASHI TOSHIHIKO
IPC: G02F1/13357
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To decrease the frequency of filter replacement by reducing dust sticking on the filter of a cooling fan. SOLUTION: The liquid crystal projector 1 serves as both a flatbed type and a ceiling suspension type and the figure shows that the projector is used as the ceiling suspension type. The flatbed type has the cooling fan 2, which protects a liquid crystal panel from the heat of a lamp below a housing and dust hardly enters the filter 3 installed in its air vent. Further, the replacement of the dirty filter is easy. When, however, this is used as the ceiling suspension type, the filter is positioned above the housing and dust easily enters it. Further, the filter replacement is not easy since the projector is installed at a high place. For the purpose, a lid 4 is provided which covers the top of the filter 3 and when the projector is used, the lid is drawn sideward with a plunger 6 to open the air vent where the filter 3 is installed.  When the projector is not in operation, the lid 3 moves onto the filter automatically with a spring 5 once the plunger is powered off, thereby closing the air vent.
