摘要： PURPOSE:To provide a clean transport system for the manufacture of semiconductor bodies. CONSTITUTION:An air curtain 4 is formed in an aslantly inside direction on a ceiling part by a high faculty filter 1 for clean air, blow-out port 2, and a guide 3, and air is allowed to circulate from a number of small diameter holes 5 for suction on a floor surface through a filter 6 and a duct 7. A ball conveyor is constituted so that metal balls 10 are installed on a table 8 and the ball conveyor 9, and the noise suppressing effect in shift is provided by lining-treating the inside of the metal plate 11 on the contact surface with resin 12, and a number of small diameter holes 13 for suction are formed also on the body itself, and the dispersion and flying-away of the generated foreign materials are prevented. Accordingly, since the metal spheres are arranged vertically and the inside is lining-treated with resin, the effect for suppressing noise and permitting the light shift is provided. Further, since partitioning by an air curtain is performed and a number of holes for suction are formed on the conveyor body, the flying-away and dispersion of fine foreign materials can be prevented.

摘要： PURPOSE:To provide a new image processing semiconductor integrated circuit device attaining a high function by a simple constitution. CONSTITUTION:A semiconductor integrated circuit is constituted of a luminance signal reproducing processing circuit 1 for receiving a recorded image signal, a chroma signal reproducing processing circuit 2 for similarly receiving the recorded image signal and a television system converting circuit 3 for selectively converting a chroma signal reproduced by the circuit 2 to a recorded TV system or a system different from the former TV system, or a luminance signal recording processing circuit for receiving a TV image signal, a TV system converting circuit for selectively converting a signal into an inputted TV system or a system different from the former TV system and a chroma signal recording processing circuit for receiving an output signal from the TV system converting circuit. Since image signal reproducing or recording processing and system coversion are constituted on the same semiconductor integrated circuit, a synchronizing signal necessary for the reproducing processing and a chrominance subcarrier generating circuit necessary for the system conversion can be shared and highly accurate signal processing can be attained by the simple constitution.

CONSTITUTION:Plant data passed through a plant input/output device 33 are inputted to a plant data table 35 by a plant input/output processing 34. A specification input passed through an input device 21 and an input control means 5 is transmitted to a display plant information editing processing 30 by a display screen request processing 20. As to specification of the sort of a language, a switch 7 for selection display output data bases 81 to 8n for discrete languages is made to operate by a switch position changeover processing 6. Based on the data from the display screen request processing 20 and a table group 10, the display plant information editing processing 30 prepares the content to be displayed in a display device 11, and it is subjected to screen display by a screen display control means 2 and the display device 11 via a display output processing 4.

摘要： PURPOSE:To obtain a plant operation guidance display device capable of easily displaying the operation guidance of each apparatus in an industrial plant by defining and storing the contents of guidance in a memory of a data input device, and when necessary extracting and displaying the stored contents. CONSTITUTION:Process data sent from each process control station through a data way 3 and a transmission controller 9 are edited by a data receiving processor 13 and transferred to a process data storing area 14. Data inputted from an input device 6 are fetched into an input control device 12 and individually processed by an input data receiving processor 15 in each processing request. For instance, an attribute 63 discriminated by an apparatus and an intra-attribute table number 64 are inputted, a picture information defining file 17 is retrieved and an optional guidance number 66 to be the detailed element of a coincident display element 60 is extracted. Guidance for the number 66 is extracted from an optional guidance definition file 20, its display is requested to a picture display processor 16 and the guidance is displayed on a graphic display device 5.

摘要： PURPOSE:To execute a continuous parallel/serial converting operation by simple constitution by bringing the most significant bit to save on a storage means, and subsequently, setting input data in parallel after the previous bit by one of the most significant bit is outputted from a shift register, and outputting the most significant bit outputted in the end from the storage means. CONSTITUTION:A latch circuit 1 for saving the most significant bit is provided, and when parallel data is located to a shift register 2 from a parallel data latch, the most significant bit is transferred to the saving latch 1, and the annihilation of the most significant bit caused by loading input data is prevented. Subsequently, after the previous bit by one of the most significant bit is outputted from the shift register 2, the next input data is set in parallel, and the most significant bit outputted in the end is outputted from the latch circuit 1. In such a way, a continuous parallel/serial converting operation can be realized by a simple circuit.

摘要： PURPOSE:To obtain a small which is excellent in resistance to environment and reliability and capable of executing an ultra-high speed processing by a method wherein photoelectric integrated circuits and/or photoelements which are coupled with each other through light rays are arranged on the inner wall of a case which is closed and shielded from external light. CONSTITUTION:Light emitting sections 40 such as light emitting diodes or lasers and photodetective sections 42 such as optical switches, which are used for coupling elements 32 with each other, are provided to the element 32. The elements 32 are mounted on the inner wall face of a dark box 30, and a mirror is provided to each corner of the dark box 30 to guide light rays between the elements 32 three-dimensionally arranged. The result processed by operation though the inner circuit of the elements 32 is converted into light rays 34 through the light emitting section 40 and successively processed by operation via the photodetective section 42 of the other element 32. By this setup, the space between the elements 32 can be made narrow, and the light emitting section 40 and the photodetective section 42 are directly connected with other, so that a small device, which is excellent in environmental resistance and reliability and capable of executing an ultra-high speed processing, can be obtained.

摘要： PURPOSE:To execute a high S/N, and simultaneously, to prevent the leak of a control signal to a signal by separate-converting a signal voltage into a positive side waveform current signal and a negative side waveform current. CONSTITUTION:An input signal Vi is separated into a positive side waveform current signal (+is) and a negative side waveform current signal (-is) by means of a positive and negative current separating circuit 1, the current signals (+is) and (-is) are supplied to gain variable circuits 2 and 3, respectively, and a gain is controlled in an equal rate according to a control signal VC. Both signals are synthesized by a signal synthesizing circuit 4, and an output signal Vo to be gain-controlled is obtained. Since the signal current Vi is separated into the positive side waveform current signal (+is) and negative side waveform current signal (-is), a circuit is made into a B class operating circuit, and a bias current is not superimposed on the signal current. Thus, since the generation of a current noise due to the bias current can be prevented, the high S/N can be obtained.
