Semiconductor elements as an N-type MOS transistor 18 and a P-type transistor 20 are formed so as to be separated by an element isolation film 16. On the other hand, an N-type MOS transistor 22 and a P-type MOS transistor 24 are formed on the P-type semiconductor substrate 10 other than a region for the elements, and a protection element is constituted. Then, an interconnection layer 38 is formed on them via an interlayer insulating film 36, and drain diffused layers for the N-type MOS transistor 22 and the P-type MOS transistor are connected to an input end. Consequently, an overvoltage can be made to escape to the substrate 10.

IPC: G01N21/64
Filed: 1979-01-24
Abstract: PURPOSE:To accomplish a surface fluorescence measurement with limited loss of the quantity of light while effectively removing effect of scattered light on the surface of the test piece by holding it in such a manner that the surface of the test piece is inclined by a fixed angle against the vertical line. CONSTITUTION:An excitation side diffraction grid 14 is so set as to be vertical in the scattering while the entrance slit 15 and the discharge slit 16 are set horizontally. The fluorescence side spectroscope 22 is arranged likewise vertical in the scattering with the slits horizontal. Therefore, the image of the slit 16 with the lens 18 and the image of the entrance slit 20 on the fluorescence side with the lens 19 are horizontal between each other. If the test piece 3 is tilted with the respect to the vertical way, effect of scattered light on the surface of the test piece can be removed effectively.

Title: Slab structure
Inventor: SATO TSUYOSHI
IPC: E04B5/02
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To increase strength and rigidity against a shearing force by applying the constitution that the lengthwise end of a precast lightweight concrete panel is fitted with reinforcements along the short side at two stages of upper and lower levels at the same positions measured from the lengthwise end, and the panel is secured to a cross member with fasteners. SOLUTION: Reinforcemnts 4 are arranged at two stages of upper and lower levels inside the lengthwise end of an ALC panel 1 along the short side at the same positions measured from the lengthwise end. In addition, the ALC panel 1 is secured to a cross member 2 with screws 3 as fasteners at the lengthwise end of the ALC panel 1 inside the reinforcements 4.

Filed: 1995-01-20
Abstract: PURPOSE: To lessen or prevent the formation of fringe patterns by interference of light even if a multilayered org. photoconductor sheet is used and a photoconductor is sensitized by coherent monochromatic light by forming the multilayered org. photoconductor sheet by using a transparent sheet, then blackening the surface of a substrate pipe stock for supporting the multilayered org. photoconductor sheet, thereby producing the conductive substrate.

Title: Liquid fuel burner
Inventor: OMUKAE YOSHIZO
IPC: F23D3/18
Filed: 1985-01-18
Abstract: PURPOSE:To eliminate almost completely the odor in flame quenching and make the burner usable without anxiety by lowering the wick into the combus tion chamber in flame quenching and at the same time communicating the wick hole with the outside air. CONSTITUTION:There is no section which retains the fuel in liquid state at sections above a flame quenching chamber 18 during flame quenching, and at the same time a shutter 9 is slid to close the flame quenching chamber 18. Since, when the wick B descends, a wick hole 4 is wide open for outside air through air inlet hole 7, a large amount of air flows into a combustion chamber 3, which reduces a great deal the suction force of the combustion chamber and lowers its temperature rapidly. Consequently the force to suck into the combustion chamber the fuel and air which later vaporize from the wick B lowered to the flame quenching chamber 18 becomes very weak. Even in the case in which they accidentally flow into the combustion chamber, they are diluted to a low fuel concentration by the large amount of air which flows in from outside through an air chamber 6.

Title: O-ring
Inventor: OHASHI KEIICHI
IPC: F16J15/10
Filed: 1987-01-14
Abstract: PURPOSE:To prevent an O-ring adapted to be used as a seal ring from being twisted and to enhanced the sealing ability thereof by forming the cross-section of the O-ring in a rectangular shape and by forming fine concave and convex parts in the outer peripheral surface of the O-ring. CONSTITUTION:An O-ring is formed in a rectangular cross-sectioned shape so as to avoid having inner and outer peripheral surfaces approximated to curved surfaces, and fine concave and convex parts 3 such that corrugated grooves of zig-zag grooves are formed on the outer peripheral surface of the O-ring. if such as O-ring is attached between, for example, members A, B and a moving member C, it is subjected to several forces in association with the movement of the member C. However, the twist of the O-ring due to these forces may be inhibited by the resistance of the corner parts S of the rectangular cross-sectioned shape. Further, an auxiliary material 4 filled on the outside of the outer peripheral surface of the O-ring is satisfactorily fixed and therefore is prevented from flowing out since the outer peripheral surface 1 is flat and is formed therein with the concave and convex parts 3. Thus, it is possible to enhance the sealing ability and to make the structure of the O-ring simple so that the cost thereof may be reduced.

Abstract: PURPOSE: To improve the properties such as temperature resistance, pressure resistance, abrasion resistance, corrosion resistance and the like by forming diamond films on the reflecting surfaces of an ATR(Attenuated Total Reflectance measurement) prism in contact with a sample. CONSTITUTION: In an ATR prism, an ATR-prism main body 10 comprising a material, whose infrared transmittance is high, is used. The main body 10 has parallel upper surface 11 and lower surface 12 as the reflecting surfaces. A side surface 13, which is to become the incident surface, and a side surface 14, which is to become the outgoing surface, are cut out so as to form 45 degrees with respect to those surfaces. Diamond thin films 20 are formed on the upper surface 11 and the lower surface 12. The cutting angle of the incident surface is changed in correspondence with the refractive index of a sample to be measured and the refractive index of the main body 10, and the incident angle is changed into the adequate value. Thus, the condition of almost total reflection can be provided as long as the refractive index of the sample to be measured is smaller than the refractive index of the diamond film 20.

Title: Tuning voltage generating circuit
Inventor: TAZAKI SATORU
IPC: H03J3/18
Filed: 1987-01-16
Abstract: PURPOSE:To prevent the deterioration in the suppressing degree of AM due to the deviation of a tuning frequency by a strong input broadcast radio wave by using a power voltage line and an output line connected to a cathode of a varactor diode including a negative stabilizing power circuit connected to the anode of the varactor diode. CONSTITUTION:Since the voltage of a Vcc line is applied to the cathode of the varactor diode directly via a high resistance, the voltage of the cathode is higher than that of the anode without fail. The output line of the negative stabilizing power supply circuit 6 for a microprocessor 42A or the like is connected to the anode of the varactor diode at the intermediate tap of a tuning coil L3 via a high resistance R2. The high resistance R2 is employed because the decrease in the Q of the tuning circuit 1 is prevented by the resistance. As a result, since the power voltage Vcc is applied to the cathode, so long as the broadcast radio wave over the Vcc does not arrive a forward current flows to the varactor diode, production of a rectified voltage due to rectification is prevented.
