Filed: 1989-03-27
Abstract: PURPOSE:To obtain an activation rate and a sharp carrier profile using annealing within normal Ar, N2, and H2 gas atmosphere without using a toxic AsH3 gas by performing annealing after forming a second film containing a high melting-point metal on an SiO2 insulating film. CONSTITUTION:The title item consists of a semi-insulation GaAs substrate 1 containing an ion-implantation region 11 on one main surface, an SiO2 insulation film 2 formed on the substrate 1 by the thermal CVD method, and a high melting-point metal silicide film 3 formed by the sputtering method. This GaAs substrate 1 is placed on a crystal glass tool 5 by sandwiching it with an Si wafer 4 and is subjected to annealing by an electrical furnace 7 within a crystal furnace center tube 6 within an Ar gas atmosphere. In this case, diffusion of Ga and As from the GaAs substrate 1 is restricted by a second film containing a high melting-point metal on the SiO2 film. Thus, activation rate and a sharp carrier profile can be obtained with improved reproduction properties within a normal atmosphere to Ar, N2, H2, etc., without using a toxic AsH3 gas.

Abstract: PURPOSE:To isolate a load capacity and accelerate the operation of a MOS type semiconductor integrated circuit by inserting two or more MOS transistors T between any circuits connected to a power supply and a grounding wire and applying reference voltage in the order or array of respective gates thereto. CONSTITUTION:When an input signal V5 becomes zero at a time t1, a parasitic capacity starts charging, a node N2 is raised to a potential VR2 at a time T6, a node N1N is abruptly raised to a potential VR1 up to a time T7, and a node N1a is further accelerated to reach a power supply voltage VDD up to a time T8. In this operation, a MOSTQ2b is turned from on to off at a time T6, and a MOSTQ2a is turned from on to off at a time T7 to isolate the parasitic capacities C2, C1b. When an input V5 is altered to VH at a time t4, the Q3 is turned on to discharge the respective parasitic capacities through the Q2a, Q2b to thus cause the respective nodes to become zero potential. When the Q2a, Q2b are thus inserted between the Q1 and the Q3 to isolate the parasitic capacity impossible to be ignored due to the Q2b via the Q1a from the output terminal 2, the rise of the potential can be remarkably accelerated.

Title: Method for judging speed
Inventor: SHIBAZAKI SOHEI
IPC: G01P3/38
Filed: 1989-03-30
Abstract: PURPOSE:To easily and accurately judge and specify the speed of a traveling object by continuously photographing the traveling object in a short period of time by a photographing means which follows up the traveling object at a specified speed and judging the magnitude of the moving speeds of the traveling object and the photographing means from the images obtd. in such a manner. CONSTITUTION:A measuring vehicle travels in follow up to an objective vehicle and photographs the objective vehicle traveling in front thereof continuously twice to obtain photographs 14, 16. The inter-vehicle distance is constant and the vehicle widths (a), (b) of the photographs 14, 16 are equal if the traveling speeds of the measuring vehicle and the objective vehicle are the same at this time. If the image of the photograph 16 is smaller than the image of the photograph 14, these images indicate that the inter-vehicle distance at the time of the 2nd photographing is longer than the inter-vehicle distance at the time of the 1st photographing and that the objective vehicle is accelerated after the 1st photographing. Judgment is then made that the objective vehicles travels at the speed higher than the measuring vehicle. The image of the objective vehicle is recorded together with the judged speed. The speeds of the objective vehicle are thus judged and specified easily with the high accuracy.

Title: Analog-to-digital converter
Inventor: UENO TAKAHIDE
IPC: H03M1/56
Filed: 1981-05-21
Abstract: PURPOSE:To reduce the converting time, by executing the change of an up/down counter from the high-order bit. CONSTITUTION:m Sets of up/down counters 8-11 of n bits per one counter are used and the conversion of N bits (N=m.n) is made by splitting the conversion into m sets. m Sets of the 1st- the m-th counters 8-11 correspond respectively from the minimum bit to the maximum bit. First, a controller 6 operates only the counter 11 at the most significant bit and converges counted values coarsely to an analog input value inputted from a terminal 21. Next, the controller 6 converges with the fineness set upward by one step by operating the (m-1)th counter 10. This operation is repeated similarly and convergence is made in the accuracy of 1/2N to complete the conversion. The content of the counters 8-11 is picked up as an output. Thus, the converting time can be improved to 2<n->N m times.
