Title: Field-effect semiconductor device and manufacture thereof
Inventor: OSADA YOSHIHIRO
IPC: H01L29/78
Filed: 1987-07-24
Abstract: PURPOSE:To obtain a field effect semiconductor device in which the minimizing of its gate width has little effect on a threshold voltage, by forming a high-concentration impurity region so as to interpose an inversion region which is inverted when a prescribed voltage is applied to a gate electrode and next preventing the high- concentration impurity region from invading the inversion region. CONSTITUTION:A resist pattern 11 is used as a mask to perform arsenic implantation 12 on the whole surface of a substrate under conditions of 30KeV in acceleration voltage and 5X10<11>cm<-2> in dosage. After the arsenic implantation, a gate oxide film 7 of 500Angstrom  in thickness is formed on an emposed P type semiconductor substrate 4 under oxidation conditions that it is held at 1000 deg.C for 10min. Then an effective impurity concentration of a P<+> impurity region 6 extending on the substrate under the gate oxide film 7 is made identical with an impurity concentration of the P type semiconductor substrate 4 by arsenic implanting diffusion of an inverted conductivity type. Namely the P<+> impurity region 6 for upgrading an effect of element isolation is limited effectively to a region under an isolation oxide film 5, not including a region under the gate oxide film 7.

IPC: C25B3/25
Filed: 1983-10-05
Abstract: PURPOSE:To manufacture efficiently potassium gold cyanide without controlling conditions of electric current during electrolysis by dispersing gold dust or grains on a horizontal electrode on the bottom of an electrolytic cell to form an anode, placing an electrode as a cathode at a distance from the anode with a diaphragm in-between, and carrying out electrolysis. CONSTITUTION:When potassium gold cyanide is manufactured by electrolysis, gold dust, grains, lumps, rods or chips are dispersed on a horizontal electrode of Ti or the like on the bottom of an electrolytic cell to form an anode, and an electrode of stainless steel or the like put in a basket of a semipermeable membrane is placed as a cathode at the center of the cell at a prescribed distance from the anode. Electrolysis is carried out by applying DC to the electrodes in a KCN soln. as an electrolytic soln. The surface area of the gold dust or the like is hardly changed only by supplying a prescribed amount of gold dust or the like in accordance with the progress of the electrolysis, and the available area of the anode can be kept almost uniform, so the control of conditions of electric current during electrolysis is not required to improve the work efficiency and productivity.

Title: Humidifier
Inventor: AKAHORI KATSUYUKI
IPC: F24F6/02
Filed: 1993-07-28
Abstract: PURPOSE:To achieve higher durability accompanied by the extension of the machine frame by providing the machine frame surrounding both of a heating for evaporating water by heating and a control means with a partition wall for diving the heating body and the control means and the partition wall with a detour to absorb the expansion of the machine frame. CONSTITUTION:When water is supplied into an evaporation tray 4 being heated with a heater 5 through a rubber hose 3 from a water tank, the water is heated and evaporated and the steam is mixed into a cooling air being carried from an air path to be scattered outside from a steam blowoff port. Inside the machine frame 1, temperature is rising with the heater 5 but the transmission of heat to the side of a control substrate 8 is blocked as the heat is shielded with the partition wall 9. Then, the partition wall 9 is provided with a relatively thin U-shaped detour part 11 to absorb the extension such as shrinkage after a molding. This enables the absorption of the most of the extension generated in the partition wall 9 effectively thereby preventing the generation of distortion, cracking and a gap of the partition wall 9.

Title: Recording medium controller
Inventor: DAIGAKU MASAAKI
IPC: G11B17/34
Filed: 1986-08-08
Abstract: PURPOSE:To hold a uniform head electromagnetic conversion characteristic in all head moving areas by making the control force of a control face, which brings a flexible rotation type magnetic recording medium into contact with a magnetic head, to the inner peripheral side stronger than that to the outer peripheral side. CONSTITUTION:A recessed part 12b formed into an approximately regular triangle is provided on the center of a sheet control face 12a of the bottom face of a pad 12, and a through-hole 12c similar to the recessed part 12b is provided in the recessed part 12b. Respective apexes of the triangle of the through-hole 12c are placed on the outer peripheral side of a sheet 2, and its center line L0 faces the moving passage of the chip part of a head 4. Since the slide control face 12a of the pad 12 is changed between the inner peripheral side and the outer peripheral side of the sheet 2 with respect to a plane, the control force in the outer peripheral side is stronger than that in the inner peripheral side of the magnetic head 4 in accordance with the angle of deformation of the sheet 2, and as the result, relations between the angle of slide of the head and the track position are sufficiently flat.

Patent JP-S5987263-A (JP)
Title: Method and device for controlling recirculation of exhaust gas from diesel engine
Inventor: JIYON AASAA KINBARII
IPC: F02D21/08
Filed: 1983-10-04
Abstract: A method and apparatus for controlling the recirculation of exhaust gas in a diesel engine includes an EGR valve responsive to an EGR control signal for relatively opening and closing a recirculation duct to the passage of exhaust gas therethrough. A sensor provides a signal indicative of the level of particulates in the exhaust gas stream. Control circuitry responsive to various signals indicative of engine operating conditions, including the signal indicative of exhaust gas particulate level, provides an EGR control signal for regulating the EGR valve at least partly as a function of the sensed level of particulates in the exhaust gas stream. The engine operating condition signals typically are indicative of the speed of the engine or fuel injection pump, the engine load, and engine operating temperature. The particulate level signal is preferably provided by electrostatically sensing the passage of packets of charged particles by an electrically-passive, annular electrode positioned in or adjacent to the exhaust gas stream. The control circuitry includes storage of open loop EGR valve control signals as a function of speed and load, as well as particulate objective signals also as a function of speed and load. The sensed exhaust gas particulate level is compared with the appropriate particulate objective signal for the development of an error signal, which error signal is then used in an adaptive manner to adjust the open loop EGR control signal in a direction to diminish the particulate error signal. Such adaptive control of the EGR control signal as a function of the exhaust gas particulate level is further advantageous because a predeterminable relationship exists between exhaust particulate levels and NOx levels as a function of percent EGR. EGR control may be inhibited by depressed engine temperature.
