Inventor: YAMAMOTO KAZUHISA
IPC: H04L7/00
Filed: 1982-06-02
Abstract: PURPOSE:To correct accurately a data error, by detecting a bit error by an error check bit and inverting a bit where an increase of an error is forecasted. CONSTITUTION:An encoder COD generates and adds the check bit to input data bits and a scrambler circuit SCR performs scrambling to output the resulting data to a transmission line. The output of the descrambler circuit DSCR of a reception side is outputted and stored in a memory circuit 102 and an error is detected on the basis of the data bits and check bit outputted to an connected error detector and decoder 100. Detected information is outputted to a code inversion indicating circuit 101 and if some bit has an error, which bit in the data in the memory circuit 102 is to be rewritten is judged according to the condition of the descrambler circuit to correct the error on the basis of the judgement result.

Filed: 1988-04-15
Abstract: PURPOSE:To discriminate a user by collating fingerprints with comparatively simple structure by previously storing fingerprint information and sending the fingerprint information together with a fingerprint number. CONSTITUTION:In fingerprint input processing, the fingerprint is stored in an IC card 2 using an exclusive-use input device 1, and after that, the fingerprint code signal of the stored fingerprint is stored in a memory 11 in the IC card 2 together with the fingerprint number.

Filed: 1987-04-17
Abstract: PURPOSE:To increase the working speed of an I<2>L (an integrated injection logic circuit) even at large currents without lowering the breakdown strength of a normal NPN transistor by forming structure in which a second epitaxial layer in low concentration is laminated onto a first epitaxial layer in high concentration. CONSTITUTION:Two-layer epitaxial-layer structure in which a first layer is formed by a first epitaxial layer 30 in high concentration and a second layer by a second epitaxial layer 300 in low concentration is shaped. When one conductivity type is represented by a P-type and the other conductivity type by an N-type, a P-type first base region 6a (a fifth region) as all internal base region in an I<2>L section A is formed so as to reach the first epitaxial layer 30 in high concentration. On the other hand, a P<+>-type base region 7c (a first region) is shaped so as to be stopped in the second epitaxial layer 300 in low concentration in a normal NPN transistor section B. Accordingly, working speed at large currents and low currents of the I<2>L can be increased without lowering the breakdown strength of the normal NPN transistor.

Title: Ingotting method of high grade steel
Inventor: NARITA KIICHI
IPC: B22D27/04
Filed: 1979-07-24
Abstract: PURPOSE: To prevent the decrease in the yield of high grade steel in forging process by removing the heat insulating material in the state that cooling and freezing have progressed by leaving the lower part of the insulating material on the surface of the molten cast metal in a mold and additionally pouring relatively low grade molten steel on the unfrozen molten steel thereby forming a gripping part.  
     CONSTITUTION: High grade molten metal 2 is poured into a mold 1 and its surface is insulated by heat insulating material 3. It is preferable to stop pouring at about 50W60mm below the top of the mold 1. If the molten metal 2 is left standing in this state, it freezes succssively from the lower or peripheral wall part, but the freezing in the lower part of the heat retaining material 3 is slowest. In the state that the cooling and freezing of the molten metal 2 have progressed by leaving the lower part of the heat insulating material 3, the heat insulating material 3 is removed and a heat resistant frame body 14 is disposed in the upper part of the mold 1, thence molten metal 5 of relatively low grade steel is poured. As a result, the molten metal 2 which has not frozen or has insufficiently frozen in the surface part fuses to the molten metal 5 integrally and the cooling and freezing of the molten metal 5 complete. This yields the cast ingot of which the body comprises the high grade steel 2' and the gripping part comprises the low-grade steel 5'.
