Title: Molecular beam crystal growth method
Inventor: SAITO JUNJI
IPC: H01L21/203
Filed: 1987-09-16
Abstract: PURPOSE:To flatten the surface layer by a method wherein hydrogen gas and the group V elements are forcibly exhausted while an ultra thin film crystal of a compound semiconductor is grown. CONSTITUTION:High purity hydrogen gas led in from a hydrogen gas leading-in port 2 of a molecular beam crystal growing device is further led in an MBE growing chamber 14 through a hydrogen leading-in nozzle 4. Hydrogen from this nozzle 4 is jetted over the surface of a GaAs substrate 6 while a natural oxide film on the substrate 6 is removed by As beam irradiation and then the substrate 6 is adjusted to the specified growing temperature. First, the shutter 10 of an As molecular beam source 8 is closed while the other shutter 11 of a Ga molecular beam source 9 is opened to start the growing process. Second, after irradiating the substrate 6 with Ga molecular beam for one molecular beam, the shutter 11 is closed and the shutter 10 of the As molecular beam source 8 is opened to irradiate the substrate 6 with As molecular beam successively the shutter 10 is closed and the substrate 6 is jetted with the gas from the nozzle 4. After repeating said growing processes, the hydrogen gas and residual molecules are forcibly exhausted by a turbo-moleculer pump 12.

Title: Connecting structure of pipes and pipe coupling
Inventor: MORITA KAZUO
IPC: F16L17/02
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To reduce the labor and the time to pull out a pipe, by providing a stopper to stop the displacement of an engaging ring to the shallow part of a taper wall, in a housing of the engaging ring. SOLUTION: When a winding pipe is connected to a pipe coupling, a taper part at the connecting tip of the winding pipe is set at the inside of a C-ring 4, and it is inserted as it is. As a result, the C-ring 4 is opened so as to pass the winding pipe, the inner diameter of a water-proof packing 7 is expanded, and the winding pipe can be inserted to the pipe stopper 3 of a coupling at a stroke. When it is made necessary to pull out the winding pipe some day, a small screw is screwed in a screw hole 13 provided at the connection 1 of the coupling, and displacement of the C-ring 4 to the shallow part of a taper surface from the innermost side of a triangular groove 5 is prevented.  By pulling out the winding pipe under such a condition, the C-ring 4 is at the deep side of the triangular groove 5 where the inner diameter is the largest, and as a result, the C-ring 4 is pushed out from the groove of the connection of the winding pipe, so as to expand the diameter, and the winding pipe can be pulled out easily.

Title: Substrate for alkaline battery and its manufacture
Inventor: ITO TAKASHI
IPC: H01M4/66
Filed: 1985-10-16
Abstract: PURPOSE:To aim at combining metal fibres firmly among each other, so as to obtain increased strength, by distributing a metal with low melting point at the concentration lower than 30wt% to alkaline resistive metal fibres made of Ni or steel etc. and then heating and cooling them in non-oxidizing or reducing atmosphere at the treatment over melting point of metal alloy with lower melting point and at the same time, below melting point of alkaline resistive metal. CONSTITUTION:Metal fibres with wire diameter of 5-100mum are made from an alloy consisting of Ni in 89% and P in 11%. The melting point of this alloy is 875 deg.C. these fibers are distributed uniformly in the ratio of less than 30wt% to the fibers of which wire diameter is 5-100mum, being made of material such as Ni or steel, thus forming felt like substance. When these fibres are heated at the temperature of 900 deg.C in a nn-oxidizing or reducing atmosphere, the alloy melts instantly and spreads over the surface of the main alkaline resistive fibers, thus sttaching a large amount of alloy to contact points among main fibres. Then, by cooling, the alloy is solidified instantly, thus combining firmly main fibres among each other, resulting in the dramatically increased strength as a felt.

Title: Music selecting method
Inventor: SAITOU KAZUMIKI
IPC: G11B27/22
Filed: 1982-12-22
Abstract: PURPOSE:To make a present music selection number coincide with a display by a simple operation without requiring a rewinding operation by putting an intrinsic discriminating number (name) to a cassette tape to discriminate it, and storing the present music selection number of the cassette tape concerned in a memory to read out the present music selection number concerned from the memory when loading to a deck, and display said number. CONSTITUTION:A cassette tape on the market sound recording plural pieces of music is loaded to a deck, also the discriminating number (for instance ''15'') of the cassette tape concerned is inputted from a ten-key, and therefore, an entry key 109b is depressed. The discriminating number ''15'' is read by a processing device 107a immediately. Thus, the processing device 107a sets a present music program number Ma under music selection to a reversible counter 112 from the storage area of an RAM 107c corresponding to the tape discriminating number ''15'', and displays it on a display part 116. Also, for instance, when the fifth music program from the head is reproduced until its middle part previously, and thereafter, the cassette tape is removed from the deck, Ma (=5) is set to the reversible counter 112 by inputting the tape discriminating number ''15'', and displayed on the display part 116.

IPC: A47C7/54
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To define a border between adjacent seats while preventing the elbows and arms of both adjacent sitters from getting into contact with each other by using an armrest member shared between adjacent seats in a plurality of chair bodies connected left and right and providing a partition wall for partitioning into left and right parts the upper surface of the armrest member. SOLUTION: Interconnected chairs have a plurality of chair bodies 1 interconnected left and right, and an armrest member 2 of the same armrest device is shared by adjacent sitters by providing a partition wall 3 for partitioning into left and right parts the arm mounting surface 2a of the upper surface of the armrest member 2. The partition wall 3 is formed high such that the sitters at both sides mounting their elbows on the armrest member 2 have their arms and elbows not in contact with each other. Thus, the chair can be used without any constraint to the adjacent sitter. Also, an uncomfortable feeling caused by getting into contact with the arms and elbows of the adjacent sitter is avoided to obtain a comfortable sitting feeling.

IPC: H04N9/28
Filed: 1987-09-18
Abstract: PURPOSE:To improve the convergence property of a color image tube by making the barrel component of the deflecting magnetic field generated by a deflecting coil at the electron gun side larger than the barrel component of the deflecting magnetic field generated by a deflecting coil at the screen side which has a larger weight function. CONSTITUTION:In the neck 9 of a vacuum envelope, an electron gun 10 is sealed up, and the electron gun 10 radiates electron beams to a fluorescent screen in the vacuum envelope. The deflecting device is composed in a saddle-saddle type, and the vertical deflecting coil is composed of two sets of saddle type coils 16 and 17. A magnetic field generated by the coil at the electron gun side has a stronger barrel magnetic field than that generated by the coil at the screen side. In such a way, two vertical deflecting coils with different magnetic field distributions are provided in the tube axis direction, and the deflecting coil at the electron gun side through which a larger deflecting current flows when the deflecting current is large has a larger barrel component than the other side deflecting coil, and so, cross patterns at the intermediate part and at the outermost part which used to be generated in the conventional device can be corrected without producing lateral discrepancy of focusing of electron beams.
