Patent JP-H095270-A (JP)
Title: Gas sensor
Inventor: NAKAHARA TAKESHI
IPC: G01N27/12
Filed: 1995-06-19
Abstract: PURPOSE: To enhance the operability of welding and to improve the resistance to heat/corrosion of a sensor by welding a metal cap to a metal base at the projecting parts of the base. CONSTITUTION: A disk-shaped metal base 4 having a flange-shaped periphery has a plurality of stems 6 fixed in the through holes of the base with glass 8. Steel, a Kovar alloy or the like is used for the base 4 and an iron/nickel alloy or the like for the stems 6, while glass having a softening point of about 500-1000 deg.C is used as the glass 8. A gas sensor main body 10 is fitted to the stem 6 and electrode pads of the main body 10 and the stems 6 are connected by lead wires 18. A metal cap 20 having an opening 22 is so disposed as to surround the main body 10 and fitted to the base 4. On the occasion, the lower end of the cap 20 is welded to the flange part in the periphery of the base 4 at projections 26 provided on the base 4. Since a welding area is small, accordingly, the operability of the welding is enhanced.  Since metals are used for both of the cap 20 and the base 4, besides, the resistance to heat/corrosion is improved.

Filed: 1988-07-18
Abstract: PURPOSE:To obtain a frequency conversion circuit having a minute frequency step with low phase noise by providing a voltage controlled oscillator at a high frequency band, a phase locked loop without any distributer and a synthesizer at a low frequency band. CONSTITUTION:A voltage controlled oscillator 11 at a high frequency band, a mixer 12 converting a 2nd intermediate frequency signal into an output frequency band, and a mixer 14 converting an input signal into the 2nd intermediate frequency band are provided. Then a mixer 16 converting an output of the voltage controlled oscillator 11 into a low frequency band, a phase comparator 17 and a synthesizer oscillator 18 for low frequency band having a minute frequency step are provided. Thus, since no frequency divider is provided to a phase locked loop I of the voltage controlled oscillator 11, the loop band is made broader and phase noise of the voltage controlled oscillator 11 is compressed at a broader band. Moreover, since the synthesizer 18 is at a low frequency band, minute step with low phase noise is attained.

Title: Manufacture of field effect transistor
Inventor: KOMINAMI MASANORI
IPC: H01L29/812
Filed: 1990-07-03
Abstract: PURPOSE:To heighten the barrier of a gate electrode and decrease the dependency of a channel layer on sheet resistance by forming a pair of high- concentration carrier layers in the channel layer by heat treatment and thermally diffusing acceptor metals in the surface region of the channel layer. CONSTITUTION:Ions are implanted into a channel layer 11 in a semiconductor substrate 10 and a pair of high-concentration carrier layers 15 are formed by heat treatment. In this heat treatment, acceptor metals 12 and 13 contained in a Schottky gate electrode 14 are thermally diffused in the surface region of the channel layer 11 to form a deep acceptor level. Therefore, the concentration of the carriers in the surface of the channel layer 11 is locally lowered and the field strength not only of the channel layer 11 but also of the interface between the Schottky gate electrode 14 and the channel layer 11 is decreased. Thereby the barrier of the Schottky gate electrode is heightened and the dependency of the channel layer on sheet resistance is decreased.

IPC: H03K3/02
Filed: 1981-11-04
Abstract: PURPOSE:To obtain a stable automatic clear circuit, by controlling a source resistance of a source follower circuit with an output of a latch circuit. CONSTITUTION:At the change of a clock phi from ''1'' to ''0'', when a latch circuit 10 reads an output of an inverter 9 as ''0'', a P-MIST19 is set off, a source follower resistance of a P-MIST6 is a resistor 7 only and the resistance value is increased, then a voltage across the resistor 7, i.e., an input voltage of the inverter 9 is increased. In taking the resistance value of the resistor 7 sufficiently larger than the ON-resistance of the P-MIST19, the input voltage of the inverter 9 after the latch circuit 10 reads ''0'' is increased in excess of a transition voltage range alpha and the output is made stable to ''0''. Even if the clock phi is ''1'' and a transfer gate 11 is opened, since the output of the inverter 9 is stable at ''0'', the output of the latch circuit 10 reamins ''0''.

Title: Manufacture of facing material
Inventor: MATSUOKA AKIRA
IPC: B32B33/00
Filed: 1982-10-08
Abstract: PURPOSE:To manufacture a facing material having a pattern whose dent part is colored, by coating a substrate, to which organic solvent-type colored synthetic resin paint has been applied, with liquid matter compatible with said resin but not having the ability to dissolve resin in it, when said substrate after being coated is not dried yet. CONSTITUTION:After a substrate is optionally undercoated, organic solvent-type colored synthetic resin paint is applied onto it. While said coating layer is still in an undried state, volatile liquid matter having compatibility with an organic solvent in said paint but not the ability to dissolve synthetic resin in said paint is immediately applied thereto. Hence, the liquid matter forms an interface between it and the paint-applied layer, and most of the synthetic resin is concentrated together with a coloring agent in the dent part of the substrate. Consequently, the facing plate excellent in decorative design is obtained.
