Patent JP-H03203244-A (JP)
Title: Method of manufacturing semiconductor device
Inventor: KONDO MASAKI
IPC: H01L29/78
Filed: 1989-12-28
Abstract: PURPOSE:To make it possible to accurately form the wall of an oxidation film formed on a side of gate silicon required for the formation of an expansion layer based on self-alignment by removing anisotropically a silicon nitriding film and a polycrystalline silicon film, and oxidizing the side of the partial residue of the polycrystalline silicon film. CONSTITUTION:A polycrystalline silicon film 104 and a nitride film 105 are anisotropically etched by RIE (Reactive Ion Etching). Then, further attempts are made to oxide and convert an exposed polycrystalline silicon film into an oxidation film 106. Pressure oxidation is applied for oxidation, which is carried out within about 5atm. This oxidation produces a differential oxidation rate between a lower concentration P-type substrate 101 and an N-type higher concentration polycrystalline silicon film 104, which makes it possible to selectively oxide only the polycrystalline silicon film 104. It is, therefore, possible to form the oxide film 106 without changing the film thickness of an oxidation film 103 to a greater extent, thereby enabling the formation of the wall of the oxidation film 106 accurately on the side of gate polycrystalline silicon required for the formation of an expansion layer by a self-alignment.

Title: Turning direction detecting device of two cycle engine
Inventor: HIROSE TOMOYUKI
IPC: F02B77/08
Filed: 1991-12-26
Abstract: PURPOSE:To improve safety by providing the turning direction detecting device of a two cycle engine in such a constitution that a time from outputting of an ignition timing signal to outputting of a cylinder judging signal is compared with the time of an intermediate point between output points of adjacent ingition timing signals so as to judge rotation of an engine in normal or reverse direction. CONSTITUTION:The output point of a cylinder judging signal is set to a point shifting from the time of an intermediate point between output points of adjacent ignition timing signals. The turning direction detecting device of a two cycle engine is constituted by comprising a means for calculating a time from outputting of the ignition timing signal to outputting of the cylinder judging signal, and an engine rotational direction judging means for judging whether an engine is rotated in normal or reverse direction by comparing a time from outputting of the calculated ignition timing signal to outputting of the cylinder judging signal with the time of the intermediate points between output points of the adjacent ignition timing signal. As a result, the engine rotation in reverse direction is detected certainly and when the engine begins its rotation in reverse direction at starting time, it is thus possible to obtain its information certainly.

Title: Method for growing at least two semiconductor layers epitaxially
Inventor: TEWS HELMUT DR
IPC: H01L21/20
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To grow a III-V semiconductor layers of different mixed crystal composition containing nitrogen epitaxially by altering the ratio of nitrogen to be fed per unit time at the time of transition from a grown layer to a layer to be grown next during a growing process. SOLUTION: A nitrogen based material satisfies the growth conditions for supplying a group III element excessively. When a plurality of elements of group III are fed simultaneously, elements being bonded most weakly are detached advantageously from all excessive elements. Consequently, elements being bonded strongly are deposited advantageously. At the time of transition from growth conditions abundant of group III elements to growth conditions abundant of nitrogen, elements being bonded more weakly are incorporated in a mixed crystal composition under growth. Consequently, the composition of a growing semiconductor layer can be influenced by simply altering a nitrogen flow.

Title: High-reliability distributed system
Inventor: NAGAURA WATARU
IPC: H04L69/40
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To guarantee that the contents of data will not be destroyed through communication software of a version by generating a transmitted message from transmitted data and then transmitted message equivalent data from the transmitted message, and deciding whether the transmitted data match the transmitted message equivalent data corresponding to the transmitted data.

The sum- processed data are written to a mailbox, and the data written to the mailbox are restored to the original data through a check sum process. Then by confirming that no abnormality is detected, it can be guaranteed that the contents of the sum process and sum-processed data have been written to the mailbox without their being destroyed. Furthermore, it is confirmed that the data to be transmitted the application program 2006 match the data after the check sum process.

Title: Electronic parts storage body
Inventor: KATSUTA SATOSHI
IPC: B65D85/86
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To enable smooth movement of coaxial lead type electronic parts contained in an electronic parts storage body one by one toward an exit in a predetermined attitude. SOLUTION: The upper edge 22 of the lead-out part 18 of an outer lead 17 delivered from a resin sealing body 16 of a coaxial lead type diode 15 supported on a support table 13 faces a guide projection 14, and the length of the folded part 19 of the outer lead 17 is longer than the height from the bottom wall 11 to the guide projection 14. The guide projection 14 projecting in parallel with the bottom wall 11 inward from each side wall 12 prevents the outer lead 17 of the diode 15 from moving upward exceeding the lead-out part 18 delivered from the resin sealing body 16.  Furthermore, because the length L4 of the folded part 19 of the outer lead 17 is longer than the height L3 from the bottom wall 11 to the guide projection 14, the rotation of the outer lead 17 in the opposite direction beyond the bottom wall 11 is also prevented, and thus the big rotation of the resin sealing body 16 can be prevented.

After the above-mentioned processes, the rotating expanding and contracting machine 6 is driven to perform the excavation together with the liquid from the pipe 3. The liquid is switched to a hardener in a prescribed depth to solidify the circumference, and sealing property is also enhanced. Thus, the excavation can be efficiently performed.
