Patent JP-H0485723-A (JP)
Title: Magnetic recording medium
Inventor: NISHIKAWA YASURO
IPC: C09D127/12
Filed: 1990-07-27
Abstract: PURPOSE:To improve peeling resistance by providing a specific fluororesin consisting of a polar unit having a polar group and a general unit having a hydrophobic property as a prospective layer on the surface of a magnetic layer. CONSTITUTION:The protective film essentially consisting of the fluororesin expressed by formula I is provided on a ferromagnetic metallic film. In the formula I, (m) is >= 1 integer and (n) is >= 10 integer. Since the polar group exists in the polar unit, the affinity of the polar group and the feromagnetic metallic film and eventually the affinity of the resin to the ferromagnetic metallic film are improved by the anchor effect of the polar group to the ferromagnetic metallic film and, therefore, the protective layer hardly peels from the ferromagnetic metallic film.

Title: Crystallization of silicon thin film
Inventor: SHIMOTORI YUTAKA
IPC: H01L29/786
Filed: 1989-07-31
Abstract: PURPOSE:To obtain an excellently crystallized silicon thin film even if a substrate which does not have any crystal nucleus such as an amorphous glass substrate at all especially as a substrate comprising a silicon thin film is adopted by using a ZnS as the ground of the silicon thin film beforehand. CONSTITUTION:As an insulating substrate, a glass substrate 1 is used. The substrate is cleaned and dried, and a ground layer 2 comprising ZnS is formed on the surface of said glass substrate 1. As a means for forming the ground layer 2, ZnS is deposited by evaporation on the glass substrate by an electron beam, and heat treatment is performed at a substrate temperature of 400 deg.C for one hour. Thus the crystalline property of ZnS is improved. An amorphous silicon layer 3 is formed on the upper surface of the ground layer 2. The silicon thin film is formed by an arbitrary means such as sputtering. Then, a laser beam 4 is projected in order to anneal the amorphous silicon layer 3, and the amorphous silicon layer 3 is crystallized. Thus, a silicon crystal thin film 3' is formed. Since the silicon crystal thin film 3' is crystallized along the orientation of the ZnS layer which is the ground layer 2, the sizes of the crystals are aligned, and the crystal film having excellent quality is obtained.

Title: Vapor growth apparatus for organic metal
Inventor: TAKAHASHI YASUHITO
IPC: H01L21/205
Filed: 1989-07-31
Abstract: PURPOSE:To prevent contamination of a carrier gas introducing pipe and to form a high-purity thin film on a large area uniformly by providing three preliminary chambers, making carrier gas flow into a reactor, mechanically scraping attached material in the reactor, and moving a susceptor into the first preliminary chamber. CONSTITUTION:Carrier gas is introduced into a preliminary chamber 7. With a differential pressure gage 11 being observed, only a supporting rod 19 is moved so that the differential pressure becomes zero. A susceptor 3 is moved into the preliminary chamber 3. A gate valve 5 is moved downward, and a reactor 1 and the preliminary chamber 7 are separated. Thereafter, the introduction of the carrier gas into the preliminary chamber 7 is stopped. The pressure in the chamber 7 is made equal to the pressure in a preliminary chamber 9. A double pipes 20 are moved, and the susceptor 3 is moved into the preliminary chamber 9. After a substrate 4 is mounted on the susceptor 3, it is moved into the reactor 1 in the reverse procedure. Since the substrates are replaced without stopping the carrier gas in the reactor, contamination of the carrier- gas introducing pipe due to the stop of the introduction of the carrier gas never occurs after the crystal growth. Therefore, the high purity crystal is readily obtained after the high concentration doping.

Abstract: PROBLEM TO BE SOLVED: To fast perform tuning in an automatic preset function in a method which detects FM multiplex broadcasting for performing an automatic preset memory for the FM multiplex broadcasting, by successively scanning received radio waves with preliminarily defined frequency step width. SOLUTION: When detecting FM multiplex broadcasting, the electric field strength detecting means 3 of an FM receiving part 1 detects the electric field strength level of a received radio wave, and a control part 2 inhibits the detection of the FM multiplex broadcasting in the part 1, when the electric field strength level is less than a fixed value.
