Title: Output buffer circuit
Inventor: FUJIWARA HISASHI
IPC: H03K19/0948
Filed: 1989-11-28
Abstract: PURPOSE:To prevent malfunction of the circuit by preventing both a PMOS transistor(TR) and an NMOS TR at an output stage from being energized simultaneously at the time of changing over an input data. CONSTITUTION:A time difference is caused in the output change in a NAND gate circuit 1 fed to the gate of a PMOS TR 3 and the output change in a NOR gate circuit 2 fed to the gate of an NMOS TR 5, both the TRs fall into a nonenergized state and the output reaches a high impedance for the period. When the output of a 2-input NAND gate circuit 1 reaches '0', the PMOS TR 3 is energized to raise the level of a data output terminal OUT to logical '1'. Since the power level and ground level of other circuit on a same integrated circuit board are not fluctuated due to a large current flowing from a power supply to ground at the time of changing over the input data, the malfunction of the circuit due to the level fluctuation is evaded.

Title: Semiconductor substrate and its manufacture
Inventor: SAKAMOTO MASARU
IPC: H01L27/12
Filed: 1993-12-10
Abstract: PURPOSE:To manufacture a semiconductor device of a high yield by preventing the film peeling at an outer part of a semiconductor substrate and then by providing a very reliable semiconductor substrate. CONSTITUTION:In a semiconductor substrate wherein an insulating film 102 and a semiconductor layer 103 are deposited in this order on a supporting substrate 101, an outer part of at least the insulating film 102 is coated with a protective film 104 which is constituted of an insulating film or a semiconductor layer. The protective film 104 is a semiconductor film made of polycrystalline silicon. Since the outer part of the insulating film 102 is protected with the protective film 104, the outer part of the insulating film 102 is never etched when the substrate is etched in a post-process and therefore the lift-off or exfoliation of the semiconductor layer 103 can be avoided.

Title: Gas sensor
Inventor: MATSUO YASUSHI
IPC: G01N27/416
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To effectively prevent a lead wire from being short-circuited by a break of a separator and prevent water or the like from invading due to a decrease in sealing performance of a grommet. SOLUTION: An outer cylinder 16 is divided to a plurality of front and rear members in an axis direction. Predetermined front outer cylindrical member 161 and rear outer cylindrical member 162 among the plurality of outer cylindrical members are coupled nearly coaxially, and a coupled part buffers heat conduction. In other words, the coupled part obstructs heat conduction, so that a high temperature state at the side of a detecting element (front side) because of heating of an engine or the like is hard to transmit to the grommet (rear side). A quantity of heat to be transmitted to the grommet 17 is reduced by the presence of the coupled part and a decrease in sealing performance of the grommet can be prevented. Moreover, the outer cylinder is coupled to a body metal fitting 9 in a state while an inner peripheral face of a front end opening part of the outer cylinder is joined directly or indirectly via the other member to an outer peripheral face of the body metal fitting. Since the outer cylinder is coupled to the body metal fitting in a manner to cover the metal fitting from outside, the outer cylinder can be easily set to the outside in a diametrical direction.

Title: Field-effect transistor
Inventor: FUJISHIRO HIRONORI
IPC: H01L29/778
Filed: 1989-11-29
Abstract: PURPOSE:To prevent a modulation in a drain current from causing even if a drain voltage becomes high by a method wherein a field-effect transistor is provided with a quantum well formation layer for accumulating holes provided in a buffer layer and an electrode for hole lead-out use, which is electrically connected with the quantum well formation layer. CONSTITUTION:A field-effect transistor is provided with a buffer layer 12 and a channel layer 16, which are provided in order on a substrate 10, and is provided with a quantum well formation layer 1 for accumulating holes provided in the layer 12 and an electrode 16 for hole lead-out use, which is electrically connected with this layer 14. When such a high drain voltage that collision ionization is caused in a channel is applied, the holes injected in a buffer layer 14b are led to an InGaAs layer 12b and are discharged to an external circuit through an electrode 18, whose potential connected with the external circuit is held in 0V or a negative potential. As the hole mobility in the layer 12b is high, a reduction in the time of a hole conduction ranging from the channel to the electrode 18 can be made small. Accordingly, a reduction in an electron potential due to the hole conduction can sufficiently be lessened.

Filed: 1989-12-01
Abstract: PURPOSE:To enable transfer high in resolution and precision irrespective of the shapes of pattern to be transferred by anisotropically etching a transparent film formed on a transparent substrate including a light-shielding member. CONSTITUTION:After the light-shielding member 2 has been formed on the surface of the transparent substrate 1, the transparent film 4 is formed on the whole surface of the substrate 1 including the member 2. At that time, the film 4 is formed in a thickness of thicker than the other places by the thickness of the member 2 near the circumferential part 2a of the member 2. Then, all the film 4 is anisotropically etched until one of the member 2 or the substrate 1 is disclosed. Since the film 4 near the circumference 2a of the member 2 is thicker, the film 4 remains along the circumference 2a of the member 2 in a thickness of almost the same as the member 2, and the phase member 3 is selectively and self-matchingly formed, thus permitting the light transmitted through only the substrate 1 and turning round into the regions of the members 3 and 2 by diffraction to interfere with the light transmitted through the member 3 and both to cancel each other, and accordingly, the light intensity distribution of the projected image of the photomask to be sharpened and high resolution to be obtained.
