Inventor: TAGATA GENICHI
IPC: H01B7/00
Filed: 1990-08-31
Abstract: PURPOSE:To provide the lead line of a pickup for an electric musical instrument which can generate various timbres by providing plural pencils of lines that are made by stranding an insulated signal line which transmits an original timbre signal and an earth line unidirectionally, and stranding these plural pencils of lines in the direction opposite to the above-mentioned stranding direction. CONSTITUTION:An earth line 12 and a signal line (hot line) 13 are stranded, for example, into a right hand wind to become a unit of strand lines of a lead line 11. These strand lines 14 in plural units are stranded in the direction opposite to the above-mentioned direction, or into a left hand wind. When a subtle original timbre signal is transmitted in the signal line 13, a deflection on its signal waveform can be generated under the influence of a magnetic field and electrostatic induction generated mutually by respective lines. Thus, a constitution under which desired timbres can be obtained by means of the lead line 11 that transmits them from a pickup close to a sounding body to a first-step amplifier, can be provided.

Abstract: PURPOSE:To obtain an oily suspension herbicide for paddy field capable of quickly diffusing by swelling of a water absorbing resin in applying to paddy field filled with water by adding a specific amount of water-absorbing resin to a system containing a herbicidal component for paddy field, a surfactant and oil. CONSTITUTION:This oily suspension herbicide for paddy field is obtained by adding a water absorbing resin (e.g. a starch/acrylic acid salt graft polymer or a carboxymethyl cellulose cross-linking system) to a system containing a herbicide for paddy field, a surfactant (e.g. nonionic surfactant) and oil (e.g. soybean oil) in a resin concentration of 0.5-50wt.%, especially 0.5-10wt.% based on the total weight.

Title: Impurity removing method for semiconductor substrate
Inventor: OKUI YOSHIKO
IPC: G01N21/88
Filed: 1993-09-17
Abstract: PURPOSE:To remove impurities efficiently from the surface of a semiconductor substrate by bringing a clean semiconductor substrate having internal strain into tight contact with the surface of a semiconductor substrate to be cleaned and then subjecting them to thermal annealing. CONSTITUTION:Clean silicon substrates 3a, 3b, each deposited with SiN, are prepared independently from a silicon substrate 1 to be cleaned where metallic impurities are present on the surfaces thereof. Since silicon has a coefficient of thermal expansion different from that of SiN, stress is generated on the interface upon cooling down to the room temperature thus causing strain. The silicon substrate 1 to be cleaned is then sandwiched by the clean silicon substrates 3a, 3b and subjected to annealing at 600 deg.C or above, e.g. at 1000 deg.C, in a nitrogen atmosphere for one hour. The impurity metal elements 4 present on the surface of the silicon substrate 1 migrate through solid phase diffusion and absorbed into the clean silicon substrates 3a, 3b around the strain present on the interface.

Title: Cordless telephone system
Inventor: TANAKA MASAYUKI
IPC: H04W4/00
Filed: 1986-09-30
Abstract: PURPOSE:To switch an off-hook state to an on-hook state at the side of a mobile equipment by detecting a howler signal at the side of a master equipment and transmitting this detection output to the mobile equipment from the master equipment via a radio line. CONSTITUTION:When a howler signal is received from a converter, a call signal detecting circuit 4 regards the howler signals as a call signal to produce the DC voltage and sends this call signal to a control circuit 5. Thus the circuit 5 decides that it received the howler signal since it is impossible to receive an incoming call in an off-hook state. Then a transmission low frequency control switch 7 is turned off and simultaneously a signal showing the reception of the howler signal is transmitted from a transmitter 12. This signal is received by a receiver 15 of the mobile equipment 3 and the receiver 15 transmits this signal to a control circuit 24. Thus the circuit 24 decides reception of the howler signal and turns off a hook switch 9 to secure an on-hook state.

Title: Formation of wiring of semiconductor device
Inventor: YAGI HARUYOSHI
IPC: H01L21/3205
Filed: 1987-09-18
Abstract: PURPOSE:To remove a natural oxide film formed on the silicon surface doing no damage to the surface preventing the natural oxide film from being formed again while a conductor film is being formed by a method wherein, before forming a wiring conductor film on a silicon surface under vacuum condition, the silicon surface is exposed to boron radical while maintaining the vacuum condition further to be heat-treated. CONSTITUTION:A processing chamber 7 wherein a silicon substrate 9 is arranged is vacuumized by a vacuum pump 5 while boronic compound gas is fed to a plasma producing chamber 4 from a flow pipe 3 and simultaneously microwave fed from a microwave producer 1 is applied to the boronic compound to produce plasma. The boronic radical produced at this time is fed to the processing chamber 7 through a feed pipe 8 and diffused in the trumpet type part of the feed pipe 8 to be applied to the silicon substrate 9 almost evenly. Consequently, the boron radical reacts to a natural oxide film to expose the surface of a silicon contact region. Furthermore, the silicon substrate 8 is vaccum-anneald to remove any residual boron absorbed to the silicon substrate 9. Later, a conductor film can be formed under the vacuum conditions such as vacuum evaporation, sputtering etc.
