摘要:
A ceramic heater comprising a ceramic substrate is described which has formed thereon a layer of a silicide of an element selected from groups IVa, Va and VIa of the periodic table. The heater has stable temperature vs. resistance characteristics, has high mechanical strength and produces the desired temperature in a very short period of time.

摘要:
It is an object of the invention to provide a video projector which can be driven by a battery and can be reduced in both size and weight. A packing case for a video projector is composed of a cabinet, which is divided into two upper and lower parts, and a cover disposed behind the cabinet. The cover is disposed removably with respect to the cabinet. By opening the cover situated behind the projector light source, a lamp forming the projector light source can be replaced easily. Also, the cover includes on the back surface thereof a battery mounting portion for mounting a battery used to drive the projector, so that the battery can be mounted to the outer back surface of the cover.
摘要:
A firing underlying board having a long use life free from thermal expansion and which does not cause twisting of ribs, deformation of an end face, color change or cracking in a honeycomb structural body fired on the underlying board. The firing underlying board is composed mainly of 55-85 wt % of cordierite and 15-45 wt % of mullite. The firing underlying board is used to fire green ceramic honeycomb structural bodies placed thereon.

By increasing, in a plant, expression of a gene or the like encoding a novel CONSTANS-LIKE protein, it is possible to promote root elongation of the plant and/or increase biomass of the plant.
摘要:
Isolated polynucleotides and polypeptides and recombinant DNA constructs useful for conferring drought tolerance, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a DTP21 polypeptide.
摘要:
In order to remove particulate matter from the exhaust gases which flow into the turbine impeller scroll of a internal combustion engine turbocharger, a separator which settles or centrifugally separates the solids from the gases is disposed between the engine manifold and the turbocharger. The separator is arranged to communicate with the turbocharger waste gate so that collected particulate matter is carried out of the device when the valve is opened to vent excessive back pressure.
