Abstract: PURPOSE:To deposit a thin film material consisting of an easily ionizable compsn. as a thin film as it is by providing a means for setting a potential difference which generates a prescribed potential difference between a vacuum vessel and a vapor source of the thin film material. CONSTITUTION:The vapor source 5 of the thin film material is provided in the vacuum vessel 2. The source 5 is connected to the minus side of a DC variable voltage power source 8 so that about 1-1,000V potential difference is generated between the vessel 2 and the source 5. The inside of the vessel 2 is maintained under about 10<-4>-10<-7>Torr and an electron beam is irradiated from an electron gun 6 to the vapor source 5 consisting of Zn1-xMnxS (0<x<1). The Zn1-xMnxS is decomposed by heating to generate the compd. ZnS, MnS but there is the potential difference between the vessel 2 and the source 5 and therefore the chemically active S ions generated by the decomposition and ionization of ZnS detach quickly from the source 5 and are hardly formed on the surface of the thin film material. The Mn effectively reaches the adhering surface and the thin film of the desired Zn1-xMnxS is obtd.

Abstract: PURPOSE:To prevent the decrease of beta of a transistor not requiring LDD structure by making transistors differently at the time of LDD structure formation so that a fine transistor has an LDD(lightly doped drain) structure and that other transistors not requiring LDD structure has approximately conventional source/drain structures. CONSTITUTION:An oxide film 8 is formed on the gate material 7 on a semiconductor substrate 6, and then a gate resist pattern 9 is formed. Next, with this gate resist pattern as a mask, the gate material 8 and the oxide film 7 are etched, and the resist is removed, and the patterns of a conductor layer 10 and an oxide film 11 are formed. Next, a resist pattern 12 is formed only in the transistor at the part not requiring LDD structure, and the canopy 11a of an oxide film is formed in the transistor requiring LDD structure by performing isotropic etching, and then the resist 12 is removed. Next, to form LDD structure, an impurity diffusion layer 13 is formed by implanting impurities of opposite type into the substrate. Next, after formation of an interlayer insulating film 14 on the whole face, the whole face is etched by RIE so as to form a sidewall 15. Next, after formation of a resist pattern where only the source and drain regions are opened, with the polysilicon and the sidewall as masks, the impurities of opposite type to the substrate are implanted in high concentration so as to form a diffusion layer 16.

Abstract: PURPOSE:To prevent the oscillation stop of the circuit due to noise in the initial state at application of power or in operation by providing a monitor circuit monitoring a voltage across a capacitor and controlling an output signal of a monostable multivibrator circuit based on an output signal of the monitor circuit. CONSTITUTION:When a capacitor 11 repeats charging/discharging, a voltage across a capacitor 11 is larger than a reference voltage VR2 of a monitor comparator 20 and the monitor comparator 20 is inactive.

Filed: 1983-12-16
Abstract: PURPOSE:To abolish an operation for breaking a runner by providing a plate- shaped body having a circular through-hole and a spherical body having the diameter larger than the diameter of said through-hole into the runner cavity. CONSTITUTION:A lower casting mold 6 is formed and a heat resistant spherical body 5 is loaded in the bottom of a runner cavity 2.

Title: Apparatus for detecting current of induction heating load
Inventor: NAGAFUNE TADAYOSHI
IPC: G01R15/18
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To detect a high frequency current with a small current transformer and obtain different outputs easily with the same current transformer, by arranging an air-core coil in proximity to a bus bar forming a power line. SOLUTION: An apparatus for detecting a current of an induction heating load is constituted by mounting an air-core coil 30 to an air-core coil-holding mechanism 31 set at a bus bar 20a. The coil 30 is, for instance, a quadrilateral of one side of (a) wound by several hundreds turns over a length lC. When a high frequency large current flows in the bus bar 20a, a magnetic field is generated in the periphery and a current corresponding to the current of the bus bar 20a is induced to the coil 30. The current is used for a signal to control outputs of a power source part, whereby the supply of power to the induction heating load can be surely conducted. When the coil 30 is mounted to the bus bar 20a in a manner to be rotatable, a count of interlinkage magnetic fluxes can be varied, thereby making a detection current variable.  Accordingly the same air-core coil can be used to control a wide range of power.

Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray fluorescent image multiplier tube device capable of easily measuring the brightness drop of an X-ray fluorescent image multiplier tube by providing a luminous element having emitted light irradiated to an input part. SOLUTION: Voltage is applied to a luminous element 21 laid at a position faced to the photoelectric surface of an input part 14, thereby generating light 22. As a result, the light 22 passes a gap between an annular grid electrode 17 and a positive electrode 18 for irradiating a part of the photoelectric surface, thereby generating photoelectrons 23. The photoelectrons 23 so generated are incident on an output phosphor 20, converted to a visible ray image and introduced outside via an output window 19. In this case, the extent of the brightness deterioration of an X-ray fluorescent image multiplier tube can be determined by measuring the degree of a drop in the brightness level of the outputted visible ray image, provided that the light quantity of the luminous element 21 is constant. Also, the luminous element 21 preferably has such a characteristic as capable of emitting the prescribed quantity of light under the application of the preset voltage.

Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To let a driver easily recognize information by providing a screen direction control means controlling the direction of a display screen, or a display means changeable the direction toward a driver's seat side, when image information is a driving support information necessary for supporting the driving of a vehicle. SOLUTION: Present direction of a display screen is judged either in a driver' s seat side or a front passenger seat side. The display screen is judged to be faced in either direction manually. The judgment is performed based on the detection results of screen direction detection parts 55a, 55b. For example in a case of a right-hand-drive vehicle, when the screen direction detection part 55a is turned on and the screen direction detection part 55b is off, it is judged to be the driver's seat side. A moving image is a television broadcasting receiving screen. When the display screen is faced to the driver side, the moving information of the display screen on a liquid crystal display part 21 is eliminated so that the driver can concentrate in driving. The driver directly recognizes the driving support information such as VICS information and navigation information.
