Patent JP-S54118167-A (JP)
Title: Semiconductor device
Inventor: TOUGEI YOSHIIKU
IPC: H01L29/04
Filed: 1978-03-07
Abstract: PURPOSE: To secure the uniform impurity distribution by selecting properly the surface of the semiconductor substrate without performing particularly the adjustment of the ion injection angle.  
     CONSTITUTION: When the ion is injected to the surface which is tilted toward the (111)-face centering on the <0-11> axis and based on the (100)-face of the Si substrate, the dispersion of the sheet resistance value is reduced with increment of the tilt angle. With tilt angle of 21° or more, the surface level density is increased gradually and inconveniently. Thus, the angle is reduced less than 20° for the practical use. The dispersion of the sheet resistance decreases gradually with 4° or more, and thus the tilt angle is preferably set to 8W20°. Particularly, an impurity atom layer can be obtained with a uniform sheet resistance value and a low surface level density by injecting the ion vertically to the semiconductor substrate.

Filed: 1988-02-08
Abstract: PURPOSE:To make best use of a display area by shifting an initial part to a work area and scrawling a remainder to a left side when character data exceeding the number of digits in the display area are inputted. CONSTITUTION:When two words of ABCD and EFGHIJ are inputted from an input means 11 to the display area which can display ten characters with a blank putting between, and there comes to be eleven words, a decision means 13 decides that the number of digits is larger than that in the display area of a display means 12, and outputs a command to a processing means 14. The processing means 14 shifts from the display area to the work area the word ABCD, in which the number of digits of inputted character data lies from the leading word in the display area to one word before the word that exceeds the number of digits in the display area, scrawls the word EFGHIJ exceeding the display area in a left direction, and displays it in the display area.

Abstract: PURPOSE: To increase the measuring accuracy and to make suitable for a variety of applications, by changing the number of turns of (n-m) sets of coils among n sets of yoke coils and receiving the signal different in the level.  
     CONSTITUTION: The yoke 8 magnetized with the magnet 9 consists of 8a, 8b and 8c. When the 7a part of impeller 5 having the magnetic substance interlinks this magnetic flux, induced electromagnetic voltage is produced in the coil 10 and output signal is received with the circuit 12. Thus, three times dense signal can be obtained with one pick-up. Further, when the number of turns of the coil 10a is more than that of 10b, 10c, the signal level of 10a is the highest among the induced electromagnetic voltages. Then, the low level signal Y is used for the calibration requiring measurement accuracy and high level signal X can count to the unit with slow response such as electromagnetic counter as the receiver.

Title: Semiconductor device
Inventor: NAKAMURA MASARU
IPC: H01L21/306
Filed: 1978-03-06
Abstract: PURPOSE: To obtain a protective film which features a high adhesive performance with the metal wiring and is also hard to receive the mechanical damage because of its hard utmost surface.  
     CONSTITUTION: The good adhesion is ensured with coating of the resin film of the polyimide or the like over the metal wiring surface on the Si substrate. Then the oxide of Cr, Ni and the like plus SiO 2 , Si 3 N 4 , etc. are laminated on the resin film, thus obtaining a soft resin protective film. As the utmost surface of the protective film is of the inorganic material, the resin is not fused when the organic agent is processed. Thus, the film can well attain the purpose of protection, enhancing the reliability of the semiconductor device.

Abstract: PURPOSE:To collate a point pattern at high speed by providing two point patterns into two-dimensional blocks, collating them respectively, finding the positions of similar blocks, and retrieving a coincident point limiting a point to the point belonging to the block corresponding to the position. CONSTITUTION:A dictionary point Q1 and an object point P1 are overlapped, and degree of coincidence between an object point II and a dictionary point XSIis found. First of all, a distance of each pair of points {P1, Q2}, {P2, Q2}, and {P3, Q2} against a dictionary point Q2 is calculated, and epsilon{1, 1; P1, Q2} is set as the minimum.

At such a time, the sum of the minimum distances is as follows; S1, 1=epsilon{1, 1; P1, Q2}+epsilon{1, 1; P3, Q3}. Such a sequence of process is applied on i=2 and 3, and j=2 and 3, and in a registration position between Pi and Qj that becomes minimum out of the sum of the minimum distances (s) (i, j), but both of (i) and (j) are 1-3, the set of object points in the pair of points which become the minimum distance coincides with the dictionary pattern XSI most similarly.

Inventor: NIITANI TOSHIMITSU
IPC: H04L5/14
Filed: 1989-02-03
Abstract: PURPOSE:To attain communication of ultra broad band and high amplification factor by utilizing a base current of a transistor(TR) whose collector is provided with a switch circuit closed with respect to a transmission signal and opened with respect to a reception signal and whose emitter receives both voltages of the transmission signal and the reception signal as the signal discrimination action.

Abstract: PURPOSE:To provide an inexpensive measuring apparatus which achieves a dialysis treatment at a proper rate of removal of body fluid by enabling relative changes in the amount of circulation blood to be measured and known bit by bit simply and in a short time with no loss of blood to be sampled from a patient. CONSTITUTION:A part of blood of a patient is taken into a conduit 5 within a container body 4 from a blood circuit 1 for measurement during a dialysis treatment to detect the blood pressure and g filtration pressure with a pressure transducer 6. A colloid osmotic pressure P is determined with a colloid osmotic pressure detecting section 8 from an input data of the pressure transducer 6 and the results are inputted into an arithmetic processing section 9. The value is substituted into an applied formula to determine the concentration C of total protein of plasma while relative changing rate of the amount of circulation blood is determined. Thus, in this structure and measuring method, the value of the arithmetic processing section 9 is shown on a display section 10 and the blood measured is returned to the blood circuit 1 to be measured bit by bit.
