Multi-chamber MOCVD growth apparatus for high performance/high throughput

In one embodiment the present invention is a method of conducting multiple step multiple chamber chemical vapor deposition while avoiding reactant memory in the relevant reaction chambers. The method includes depositing a layer of semiconductor material on a substrate using vapor deposition in a first deposition chamber followed by evacuation of the growth chamber to reduce vapor deposition source gases remaining in the first deposition chamber after the deposition growth and prior to opening the chamber. The substrate is transferred to a second deposition chamber while isolating the first deposition chamber from the second deposition chamber to prevent reactants present in the first chamber from affecting deposition in the second chamber and while maintaining an ambient that minimizes or eliminates growth stop effects. After the transferring step, an additional layer of a different semiconductor material is deposited on the first deposited layer in the second chamber using vapor deposition.

An image recording medium for recording image information by storing electric charges generated in response to exposure to an electromagnetic wave carrying the image information. The image recording medium includes: an electrode transparent to the electromagnetic wave; a recording-side photoconductive layer which contains a-Se as a main component, and generates electric charges when exposed to the electromagnetic wave; and a suppression layer which is arranged between the electrode and the recording-side photoconductive layer, and suppresses interfacial crystallization in the recording-side photoconductive layer. The suppression layer is made of an organic material which behaves as an insulator against electric charges having the opposite polarity to electric charges which move from the recording-side photoconductive layer to the electrode at the time of recording, and as a conductor of charges having the same polarity as the electric charges which move to the electrode.

Hybrid vehicle mode-switching control device

A hybrid vehicle mode-switching control device for a hybrid vehicle controls that an output of an engine and / or motor in response to a mode-switch request. In a case of a difference between an actual transmission gear ratio and a target transmission gear ratio, a deficit with respect to the requested drive power occurs that causes discomfort to the driver. The drive power surplus or deficit caused by the transmission gear ratio deviation can eliminated by correcting of the motor torque and / or the engine torque by a correction amount necessary to eliminate the surplus or deficit of drive power. In this way, the lack of drive power due to the transmission ratio deviation and the driver's sense of discomfort can be eliminated.

Reaction tube, process for producing catalyst and process for producing unsaturated aldehyde and unsaturated carboxylic acid

In producing a catalyst used for synthesis of an unsaturated aldehyde and an unsaturated carboxylic acid by a gas-phase catalytic oxidation, there is used a step of packing an additive-containing catalyst precursor of the catalyst into a tubular reactor, passing a gas through the tubular reactor, and elevating, in this state, the temperature of the additive-containing catalyst precursor so that a temperature of the gas at an outlet of the catalyst precursor layer becomes higher than a temperature of the gas at an inlet of the catalyst precursor layer. The step makes possible easy and highly reproducible production of a high-performance catalyst which is small in the reduction in catalytic performance caused by, for example, the thermal decomposition of the additive contained in the catalyst precursor.

Method and system for radio communication with mobile units

The invention concerns a system and a method of radio communication between a plurality of mobile units (6) and a stationary system (1, 3, 12, 14) comprising one or several transmitter units (3), wherein radio communication to one or several mobile units (6) is effected by broadcasting from one of said emitter units (3) on a first, public frequency. The stationary system further comprises a plurality of stationary receiver units (12), said units being connected to a central unit (1) via a common data communication network (14), radio communication from the mobile units (6) being effected by transmitting on a second, public frequency a burst of radio messages (25) that are receivable only by a small number of receiver units (12). From the receiver units (12) the messages are forwarded via the data communication network (14) to the central unit (1), which selects one of the forwarded messages and reads the data contained in the message. The system in accordance with the invention therefore does not require that designated communication paths be established with each communicating unit, and since only a small number of receiver units (12) receive each transmitted message, all messages may be transmitted on the same frequency. Alternative frequencies could however be utilised, for example when longer messages are to be transmitted.
