A process for preparing .alpha.-ketobutyric acid comprising contacting 1,2-butanediol with molecular oxygen in the presence of a platinum catalyst is disclosed. The process produces .alpha.-ketobutyric acid in high yield at low cost.
摘要:
A microwave plasma film deposition system comprises a waveguide for feeding microwaves through a microwave feeding window provided at one end of the waveguide, and a plasma cavity in communication with the other end of the waveguide and having a discharge gas inlet which is not in communication with the waveguide. The system further includes a specimen chamber which is in communication with the plasma cavity and which has a substrate setting rest therein and a material gas inlet, and a magnetic field applying device provided near the plasma cavity. Stable film deposition occurs because the plasma cavity is at the end of the waveguide which is remote from the microwave feeding window, whereby deposition on the microwave feeding window is prevented. Deposition on the microwave feeding window is further prevented by a ferromagnetic material which is placed around the waveguide and which reduces the strength of the magnetic field in the waveguide.
摘要:
The present invention resides in a control apparatus for an internal combustion engine in which selective use is made of a case where a first fuel, being easy to be ignited, is caused to combust by itself, and a case where a second fuel, being hard to be ignited, is also caused to combust by igniting said first fuel, and which is provided with an acquisition unit configured to acquire a combustion state of said second fuel in the case where said second fuel is also caused to combust by igniting said first fuel, and a decision unit configured to decide amounts of supply of said first fuel and said second fuel to be supplied to said internal combustion engine on and after next time, based on the combustion state of said second fuel determined by said acquisition unit.

An image processing apparatus includes: an image information input unit which receives input of first image information; and a sharpness adjustment unit which divides a screen image corresponding to the first image information into a plurality of areas and performs a sharpness adjustment for each of the divided areas to output second image information.
摘要:
To realize high performance and low power consumption of a semiconductor device by controlling electric characteristics of a transistor in accordance with a required function. Further, to manufacture such a semiconductor device with high yield and high productivity without complicating a manufacturing process. An impurity element imparting one conductivity type is added to a semiconductor substrate in order to control the threshold voltage of a transistor included in the semiconductor device, before separating a semiconductor layer of the transistor from the semiconductor substrate and transferring the semiconductor layer to a supporting substrate that is a substrate having an insulating surface.

To provide a stacked mounting structure in which the number of semiconductor chips that can be stacked is greater than conventionally, as well as a method for fabricating the same, each semiconductor chip has electrodes provided at least at one end in the stacked mounting structure, and a board holding the semiconductor chips at the one end is folded with at least two of the semiconductor chips being stacked so as to at least partially overlap with each other.
摘要:
A method for manufacturing a head-gimbal assembly. The head-gimbal assembly includes a head-slider bonded to a suspension. The method includes placing the head-slider and the suspension in a superposed manner with a photo-thermosetting adhesive applied between the head-slider and the suspension. The method also includes heating the suspension from a side of the suspension opposite to a side of the suspension in contact with the photo-thermosetting adhesive with a heated gas-stream. In addition, the method includes irradiating the photo-thermosetting adhesive with light at least partly in a time period during which the suspension is heated by the gas-stream.
