Abstract: PURPOSE:To facilitate highly accurate mask alignment by a method wherein markers are provided at positions inner than the circumference part of a semiconductor substrate so as to be within the range of vision of a microscope and the markers are formed as protrusions whose height is the same as the height of cathode regions. CONSTITUTION:Markers 6 are provided at positions inner than the circumference part of a silicon substrate and about the middle of the radius and are formed as cross-shape protrusions whose top surfaces are in the same plane as the surfaces of cathode regions 2. The markers 6 are formed at the same time and by the same method, a so-called grooving etching method, as the formation of steps for separating the cathode regions 2 and the gate region 3 of the silicon substrate 1 with a PNPN four-layer structure. In other words, after an oxide film is formed on the substrate surface, parts of the oxide film with a cross shape are left in addition to the pattern of the cathode regions 2 and the markers 6 are formed by grooving etching with a mixed acid etchant consisting of hydrofluoric acid and nitric acid to the depth of about 30mum from the silicon substrate 1 surface. Therefore, these makers adhere tightly to the surface of a mask which is to adhere tightly to the substrate 1.

Filed: 1988-05-12
Abstract: PURPOSE:To realize the execution of a sequence controller only for the scan time required for the number of input/output points used for a program with no dependence on the program step by securing such a constitution where plural unit circuits decide the conditions at one time with a single reading action even in case these unit circuits are processed in parallel and used plural times by the program at reading of the contact input of a sequence executing part. CONSTITUTION:A unit circuit production means 8 is prepared together with the unit circuit storage means 3a-3c, an input scan sequence production means 10, an input sequence memory 16, and a sequence executing part 4. In such a constitution, the programs of plural unit circuits are run at one time. Thus it is possible to process the input scan just with a single access given to a single contact regardless of the using frequencies of programs. Then an output means of an OR address code 14 is added together with the OR memories 9 and 9a-9e set for each OR address, and an OR instruction processing circuit. Thus it is possible to eliminate the processing sequence of the unit circuits. Furthermore the constitution is simplified for both means 8 and 10.

Abstract: PURPOSE: To enable the accurate detection of vehicles and constant knowing of road condition to be performed by providing a microprocessor and always knowing the time until the reflected waves from road surface are received.  
     CONSTITUTION: If it is assumed that the ultrasonic pulses transmitted at t' 0  are received at t' 4 , then said time t' 4  varies within the predetermined range of ±α. A vehicle judgement threshold value is assumed to be β. The time when the reflected waves from the road surface are received, e.g., t' 4  is stored in a specified area by a microprocessor, and the difference (a) between the time of the reflected waves of this time and t' 4  is next computed. If the difference (a) is below α, the reflected waves are judged to be the reflected waves from the road surface and the previously stored data t' 4  is renewed. If (a) is larger than β, the waves are judged to be the reflected waves from a vehicle and a vihicle detection signal is outputted. In this way, the data hiving been stored in the required areas at every period of projecting ultrasonic waves are sent as outputs to a central control room. Hence, the condition of the road may be known without requiring a multiplicity of level detectors
