When a disproportionated chlorosilane is to be produced by causing a starting material chlorosilane liquid to flow through a catalyst-packed layer which is packed with a weakly basic anion exchange resin as a disproportionation reaction catalyst to carry out a disproportionation reaction, before the disproportionation reaction is carried out, the disproportionation reaction catalyst is brought into contact with a processing gas obtained by diluting a chlorosilane with an inert gas to prevent the deterioration of the disproportionation reaction catalyst at the start of the reaction so as to carry out the disproportionation of the chlorosilane efficiently.

Provided is a measuring chip, which can spot a specimen liquid of a minute quantity for an immune agglutination easily and precisely to the measuring chip and which can prevent the flow of the specimen liquid and the contamination of the specimen. The measuring chip comprises at least two substrates, a spacer arranged between the substrates, at least one passage made of the substrates and the spacer into a hollow shape and having two open ends, counter electrodes for applying an electric field, and a specimen-spotted portion to be spotted with the specimen. The specimen-spotted portion has a structure made of a square, circular, elliptical or sector shape by that spacer. Moreover, the specimen-spotted portion has two open ends, one of which is connected to one open end of that passage.

A substrate having a channel portion in which a liquid transfers, wherein, even if the channel portion has no micro-channel interconnecting chambers, a liquid can transfer stepwise from one region to the next region according to the speed of rotation of the substrate. The substrate can be rotated about a rotation axis as the center, and has the channel portion including the chambers formed therein. The inner wall of each chamber has a first area including an area intersecting with a centrifugal direction from the center; and also has a second area placed at a position farther from the center than the first area, and including a surface intersecting with the centrifugal direction from the center. Further, the first area has a region for holding a droplet of a liquid provided; and also has a region where a contact with the droplet expands when the substrate is rotated, and that communicate with the second area.

A sample liquid analytical chip that whilst being of simple structure, has a reaction region and a detection region isolated from each other and further has liquid feed control means for a sample liquid, thereby realizing speedy reliable analysis. The sample liquid analytical chip comprises a tubular sample liquid transfer channel with its both ends open, a reaction reagent layer disposed on the internal wall surface of the sample liquid transfer channel and a detection region for detecting any physical or chemical change of the sample liquid. In the sample liquid analytical chip, the sample liquid transfer channel at an area of its wall surface is provided an opening and a lid fitted to the opening. Portion of the lid forms a hinge in cooperation with the wall surface.

A catalyst carrier which includes a catalyst support layer containing an alkaline earth metal and/or an alkali metal disposed on an alumina substrate. The alkaline earth metal and/or the alkali metal is suppressed or prevented from diffusing into the substrate to react with alumina in the substrate. A catalyst support layer 3 that contains an alkaline earth metal and/or an alkali metal is formed on a surface of an alumina substrate 1 having a three-dimensional network structure. A zirconia layer 2 consisting of zirconia and/or stabilized zirconia is disposed between the substrate 1 and the catalyst support layer 3. The zirconia layer 2 has a thickness of 3 μm or more in a region of at least 65% of the substrate surface. The zirconia layer suppresses or prevents the alkaline earth metal and/or the alkali metal in the catalyst support layer from diffusing into the substrate.
摘要:
A light source device with a mercury lamp, in the case of formation of a bridging short circuit of the gap between the electrodes of the discharge lamp caused by mercury, to prevent the light source device from no longer being usable because the difference between a defective device and one with such a bridging short circuit cannot be ascertained, has a means for determining that a bridging short circuit has formed in the gap between the electrodes. Furthermore, various manners for eliminating the bridging short circuit are provided including those that make use of vibration, heat, dielectric discharge or Lorenz forces.

The present invention discloses a receiver and a receiving method for spread spectrum communication for use in the digital communication system. The receiver basically comprises a receiving circuit, a spread signal distributing circuit, a pseudo noise signal generating circuit, an activating circuit, correlation detecting circuits, an initial seizing control circuit, a synchronization sustaining control circuit, a synchronization control circuit and a demodulating circuit. If a phase lock condition is broken within a short period of time, such condition is sustained until phase lock is recovered so that communication can be started again immediately after phase lock is recovered without initialization for each asynchronization. The receiving circuit is very much simplified and particularly, the Costas Loop demodulating circuit detects the phase lock condition when the signal obtained by multiplying the signal of which phase is shifted by 90.degree. and the reversely spread signal is within the preset range without using a phase shifter or other multiplying circuit. Accordingly the circuit structure of the receiver as a whole can be simplified.

A safety device to prevent a vehicle-loaded electronic equipment from malfunctioning due to an influence of the high-level electric field. An antenna pattern for detecting the electric field is formed on the same printed board as the electronic equipment, and an electric signal level of the output from the antenna pattern is determined. When the determined level reaches a level at which the electronic equipment may malfunction, the equipment is forcibly controlled toward a safety range of operation.
