摘要： PURPOSE:To enable to assemble the A/D conversion circuit in an intergrated circuit, by selecting the bias voltage fed to one end of the storage means to groud voltage. CONSTITUTION:After the switches S1 and S3 are turned on and the capacitance voltage V1 is charged up, the point A is lifted up by VB with S4 turned on and discharge is made by turning on S2. Although this operation is the same as conventional methods, afrer the end of detection, the short circuit S5 is first turned on. As the result, the point a is equal to the bias voltage VB as the point B. After that, when S3 is turned on, the point A is not at a negative potential. Accordingly, in an integrated circuit constitution, the occurence of negative voltage can be avoided as conventionally. Thus, the condidtion is satisfied with the A/D conversion circuit not allowing to generate the negative voltage in the circuit, and if the input voltage V1 is smaller than the detected voltage VT, the A/D conversion circuit measurable can be offered, and concretely, the A/D conversion circuit using monolythic MOS process can be assembled in an integrated circuit.

摘要： PURPOSE:To enable to perform the positonal adjustment of a light-emitting or light-receiving element and an optical fiber by a method wherein said optical fiber is supported by a rigid supporting member, and then it is supported by a plastic deformation member. CONSTITUTION:A semiconductor laser 11 is mounted on a sheath 10 together with a laser mount 12 and the positioning of the optical fiber is performed in advance in such a manner that an output beam will be coupled in a certain degree with the point part 13 of the optical fiber. The supporting cylinder 14 connected to the circumference of a cylinder 7 is formed using a rigid type of material with which the curve of the center axis of a stainless cylinder 7 and an optical fiber 4 will be elastically connected without generating a steep curved part. Displacements (x) and (y) are given to the plastic deformation member and then they are removed on the inner surface of the (x) and (y) which are intersecting at right angle with the laser beam emitting direction Z using a fine adjustment device while monitoring the fiber output obtained by passing an output laser beam through the optical fiber 4, and the amounts of displacement DELTAx and DELTAy are found out. At the same time, the maximum value is obtained by balancing the increased portion of output while reducing the amount of adjustment successively so as to obtain the maximum value which is in excess of the value estabilished in advance under the state wherein the value of output beam is being monitored.

摘要： PURPOSE:To plan to simplify a manufacturing process by a method wherein double field ions of a P type impurity and double enhancement ions of the P type and N type impurities are injected. CONSTITUTION:An N-well 302 is formed in the P type substrate 301 in low concentration. Then, the P type impurity layer 306 is formed in the substrate 301 in the use of a mask for controlling the impurity concentration. Then again, an impurity having selectively a concentration sloping in the direction of depth is added to a region on which an N type and P type active transistors are formed to form an N type impurity layer 308 lower in concentration than that of the layer 304 and a P type impurity layer 310 lower in concentration than that of the layer 306. By forming the layer 308 and the layer 310 in such a manner, the two masks for controlling the impurity concentration are disused and the manufacturing process can be simplified.
