Title: Epitaxial wafer and manufacture thereof
Inventor: MIKI KATSUHIKO
IPC: H01L21/316
Filed: 1989-01-26
Abstract: PURPOSE:To enable the removal of a protective film to be performed simultaneously with the mirror processing of a substrate by a method wherein a protective film for autodoping prevention is provided on the side and the rear surface of a semiconductor substrate and when an epitaxial layer is directly deposited on the surface in such a state, an OH radical exceeding specific weight % is contained in the protective film. CONSTITUTION:For example, e.g. a P-type epitaxial layer 3 is deposited on the surface of e.g. a P-type substrate after coating the side and rear surface of the Si substrate 1 with an SiO2 protective film 2 for autodoping prevention. At this time, an OH radical exceeding 3weight% is contained in the protective film 2. Furthermore, the thickness of the preventive film 2 is specified to exceed 0.3mum while the protective film 2 is removed simultaneously with the later processing of the substrate 1. That is, the hardness of the film 2 is made lower than that of normally applied CVD oxide film so that any special process for removing the film may be eliminated to augment the throughput in the semiconductor manufacturing process.

Filed: 1986-01-31
Abstract: PURPOSE:To most suitably encode all pictures with respect to picture quality and transmission efficiency by selecting one of two processing means and one of two encoding means in accordance with the deciding result of a picture quality deciding circuit to encode pictures. CONSTITUTION:An input signal is binarized by a binarizing circuit 102 and is sent to an encoding part MR 105.

The switch 104 selects the signal, which does not pass the reducer 103, if a high resolution is decided by a picture quality deciding part 108, but the switch 104 selects the signal, which passes the reducer 103, if a low resolution is discriminated. The output of the switch 104 is sent to a cosine conversion operating part 106, and each block is subjected to cosine conversion. Converted data is quantized and is sent to a converter 107, and the converter 107 selects and outputs the code due to binary encoding if the picture is binary, but the converter 107 selects and outputs the code due to cosine conversion encoding if the picture has a variable contrast.

Title: Exhaust emission control device for engine
Inventor: TANAKA KAZUAKI
IPC: F02M25/07
Filed: 1993-01-07
Abstract: PURPOSE:To maintain purifying performance and prevent a device from becoming large-sized by providing a recirculation executing means for receiving the output of an NOx catalyst temperature detecting means and operating an exhaust gas recirculation system on the high temperature side out of a predetermined temperature range so as to recirculate exhaust gas. CONSTITUTION:An engine 1 is provided with a control unit 13 for controlling an air-fuel ratio by the control of a fuel injection valve 7. The area of lean-burn control for controlling the air-fuel ratio to the leaner side set air-fuel ratio than a stoichiometric air-fuel ratio is preset by the rotating speed and load of the engine 1, and the range of catalyst inlet gas temperature corresponding to the range of catalyst temperature enabling the attainment of a required purifying factor by an NOx catalyst 8 in the lean-burn state is press. In the case of the catalyst temperature being shifted onto the high temperature side, the air-fuel ratio control is changed over to lambda=1 control along with EGR (exhaust gas recirculation). The purifying performance can be thereby maintained by the exhaust gas recirculation in the area where the temperature of the NOx catalyst 8 is high to cause the fall of the purifying factor, and a device is prevented from becoming large-sized.
