摘要:
A leaf-type clock driven by a intermittent and segmental rotation by using so called Geneva-gear mechanism to cause turning-over of the time- and minute-indicating leaves is disclosed. This leaf-type clock has the advantages that number of the leaves may be reduced, and that the time accuracy is improved, and further that small-sized clock can be designed.
摘要:
A digital display clock including a one-minute indicating wheel, a ten-minute indicating wheel and an hour indicating wheel which are driven by intermittent and segmental rotations through separately provided Geneva-gear mechanisms for each individual indicating section, a driving system arranged in the back of digital clock, so that the clock is able to provide a wide and effective display area in front of the clock and an excellent design for a 24 hour display digital clock with diversity.
摘要:

摘要:
A vacuum evaporator is characterized in that hot-cathode filaments (7) are provided as the electron source around a tip of a rod evaporation material (4); the peripheries of the rod evaporation material (4) and the hot-cathode filaments (7) are disposed in parallel to a conductive cooling member (1) of a good heat conductive metal which is partly contacted with the atmosphere to decrease the dissipation of radiation heat produced from the hot-cathode filaments (7) and a tip (41) of the rod evaporation material (4) into a vacuum vessel a; heat absorbed by the conductive cooling member (1) is quickly conducted through the conductive cooling member and discharged to the atmosphere to prevent the temperature of the electron impact heating part from increasing and to prevent the increase of the gas discharge due to the heat dissipation from the electron impact heating part.

A composition consisting essentially of a diaryl carbonate and contains a furan ring-containing compound in an amount of not more than 1 ppm is favorably employable for producing less colored polycarbonate.
摘要:
A laser marking resin composition excellent in appearance of molded article and impact resistance which comprises: (A) 100 parts by weight of a rubber-reinforced vinyl resin consisting of: (A-1) 1 to 100% by weight of a rubber-reinforced resin having a grafting degree of 5 to 150% by weight obtained by polymerizing, in the presence of (a) 5 to 70% by weight of a rubbery polymer, (b) 95 to 30% by weight of at least one monomer selected from the group consisting of an aromatic vinyl compound, a vinyl cyanide compound, a (meth)acrylic acid ester, maleic anhydride and a maleimide compound, provided that (a)+(b)=100% by weight, and (A-2) 99 to 0% by weight of a polymer obtained by polymerizing at least one monomer selected from the group consisting of an aromatic vinyl compound, a vinyl cyanide compound, a (meth)acrylic acid ester, maleic anhydride and a maleimide compound, provided that (A-1)+(A-2)=100% by weight, the matrix resin in the component (A) having an intrinsic viscosity �.eta.! of 0.1 to 1.5 dl/g as measured in methyl ethyl ketone at 30.degree. C., and (B) 0.01 to 30 parts by weight of at least one compound selected from the group consisting of (B-1) titanium black, (B-2) black iron oxide, (B-3) yellow iron oxide and (B-4) carbon black.
摘要:
Disclosed is a vacuum container for transporting one or more articles in the vacuum atomsphere. To this end, the vacuum container comprises a container body which can be maintained in the air-tight state and which is formed with a hole through which one or more articles are inserted into or removed out of said container body, a gate valve for opening or closing the opening of the container body, vacuum maintaining pump means communicated with the container body in order to maintain the interior thereof at an extremely high degree of vacuum and retaining means disposed within the container body for releasably retaining at least one article. With the vacuum container with the above-described construction, one or more articles which cannot be exposed to the surrounding atmosphere because of various reasons can be transported in the vacuum state in a stable manner.
