IPC: H01L29/80
Filed: 1985-10-11
Abstract: PURPOSE:To elevate the barrier of a gate electrode part by a method wherein a thin film of impurity which provides a conductivity type different from that of the 1st semiconductor layer is formed on the 1st semiconductor layer by performing an evaporation and a heat treatment for impurity diffusion. CONSTITUTION:A nondoped gallium arsenite layer 2, a nondoped gallium-aluminum arsenite layer 3, an N-type gallium-aluminum arsenite layer 4 and an N-type gallium arsenite layer 5 are successively formed and laminated on a semi-insulating gallium arsenite substrate 1 by a vapor phase deposition method and further a film 6 of zinc, which is P-type impurity, is evaporated. If this semiconductor device is subjected to a heat treatment at 250-350 deg.C, the zinc is diffused into the semiconductor layer 5 to form a P-type conductive layer 6' near the surface. Further, after a gate electrode 7, a source electrode 8 and a drain electrode 9 are formed, the P-type semiconductor layer 6' is removed by etching except the part directly under the gate electrode. Therefore, as the P-type semiconductor layer 6' is provided under the gate electrode only, the height of the barrier of the gate electrode part can be made to be higher than the surface potential between the source and the gate. With this constitution, even in a normally-OFF type FET, increase of source resistance can be suppressed.

Title: Foil wound transformer
Inventor: TODA KATSUTOSHI
IPC: H01F27/28
Filed: 1984-10-30
Abstract: PURPOSE:To improve workability by providing an arrangement in which a metal plate to which a lead wire is soldered or welded and a metal sheet are layed one upon another so that the pressure-welded portions of the two becomes an outer edge, thereby eliminating the necessity of a large-sized pressure welding apparatus having deep bosom. CONSTITUTION:A metal plate 3 and a lead wire 2 are previously soldered or pressure- welded at a plane A. The metal plate 3 to which the lead wire 2 is fixed and a metal sheet 1 are arranged so that the outer end of the side of the metal plate 3 to which the lead wire 2 is not fixed overlaps the outer edge in the peripheral direction of the metal sheet 1, and the outer end and edge of these metal sheet 1 and metal plate 3 are fixed to each other by low temperature pressure welding. Since the lead wire 2 is soldered or welded to the metal plate 3, it becomes unnecessary to directly fix the lead wire 2 to the metal sheet 1 through soldering or welding, eliminating deforma tion or melting of the metal sheet 1. Moreover, since the pressure-welding faces of the metal plate 3 and metal sheet 1 are positioned at the outer edges of the metal sheet 1 and metal plate 3, a large-sized pressure welding apparatus having deep bosom becomes unnecessary, and pressure welding can be performed by a small-sized pressure welding apparatus.

Filed: 1993-09-13
Abstract: PURPOSE:To provide a comparison amplifier circuit for which the duty of output signals when input signals are present is not degraded even though it is provided with a function for turning a signal output terminal to a non-signal state when the input signals are not present by providing a signal interruption detection circuit and a current absorbing circuit for absorbing the current of a control current source by the detection signals of the detection circuit. CONSTITUTION:When the input signals 11 are present, since the signal interruption detection circuit 8 does not output the detection signals, the current absorbing circuit 26 does not absorb a control current 14, a reference current 13 is a prescribed value and the multiplication factor of a comparison amplifier 1 is the prescribed value as well. In the meantime, both negative phase input terminal and positive phase input terminal of the comparison amplifier 1 are accurately the potential of a reference power supply 3. Thus, the output signals 12 with no degradation of the duty are obtained. On the other hand, when the input signals 11 are not present, since the signal interruption detection circuit 8 outputs the detection signals, the current absorbing circuit 26 generates an absorbing current 27, absorbs the control current 14 and interrupts the reference current 13 and the signal output terminal 10 is turned to the non-signal state.

Title: Manufacture of semiconductor device having redundant circuit
Inventor: SASAKI NOBUO
IPC: H01L27/092
Filed: 1983-11-30
Abstract: PURPOSE:To enable the increase in integration without the need of fuse element by a method wherein lines are separated and/or connected by varying the threshold value on laser irradiation of a MOS transistor. CONSTITUTION:In an inverter circuit comprising of a P-channel MOS transistor (Tp) and an N-channel transistor (Tn), the threshold value of Tp, Vth=0.7 and that of Tn, Vth=+0.7V should hold. When a signal of 0-5V comes into the input 3 with the power source voltage Vcc=5V, an inversion signal appears at the output 4. Here, variation of the Vth of Tp to -6V on irradiation of Tp and Tp with laser powers of the same strength causes Tn to vary in Vth to about -5V. In such a manner, the input is 0-+5V, Tn is always ON, Tp is always OFF, and the output is 0V; that is, the signal line can be cut. Next, in the case of connecting the signal line, Tn always turns OFF and Tp always ON; therefore the ouput is always 5V. On laser power irradiation, the Vth of Tp can be varied to -0.7V, and the Vth of Tn to +0.7; accordingly, the output comes to vary on the basis of the signal of input 0-5V.

IPC: G01B11/00
Filed: 1985-10-15
Abstract: PURPOSE:To enable the measurement of the distance up to a multidirectional matter, by allowing luminous flux to be incident on a rotary flat reflective mirror and scanning matter to be measured while the reflected luminous flux thereof is projected to said matter to be measured and reflecting the reflected luminous flux from the matter to be measured by the flat reflective mirror to form an image. CONSTITUTION:The parallel luminous flux emitted from a light source 1 is converged to the focal position of a convex lens 5 by a convex lens 2 are reflected by a flat reflective mirror 3 and a rotary flat reflective mirror 4 and the reflected luminous flux passes through the lens 5 to be converted to parallel luminous flux which is, in turn, incident on matter to be measured to be reflected therefrom. A part of the reflected luminous flux from said matter passes through the lens 5 and reflected by the mirror 4 to form an image on a photoelectric converter element 6. The image forming positions A, B are determined by the distance up to the matter. Therefore, if the relation between the image forming position on the element 6 and the distance up to the matter is preliminarily calculated, the distance up to the matter can be immediately detected from the output of the element 6. The mirror 4 has six flat reflective surfaces and, by succeedingly rotating the mirror 4 around a rotary shaft, the distance up to the matter present in a predetermined angular range can be repeatedly and continuously measured at a high speed successively using adjacent reflective surfaces.
