Abstract: PROBLEM TO BE SOLVED: To make possible an easy formation of an ohmic junction and a low-density P-type layer which exhibit a good adhesion strength as a back side electrode. SOLUTION: In a sectional view of an IGBT(insulated gate bipolar transistor), a P<+> type well area in which a high-density P-type is introduced, gate electrodes 2 on gate insulating films, a P-type base area 3, N<+> type emitter areas 4, insulating films 5 and an emitter electrode 6 are formed on the surface of an N-type silicon substrate 1. A collector electrode 7 on the underside is made of aluminum doped with boron or an alloy of aluminum as electrode material. A low-density P-type layer 8 (P-layer) is formed adjacent to the collector electrode 7. The collector electrode 7 forms a good low-resistance ohmic contact with the aid of difference in diffusion efficiency between aluminum and boron by easier melt anneal method.

Title: Error correcting device for digital picture signal
Inventor: YANAGIHARA HISAFUMI
IPC: H04N19/86
Filed: 1992-10-23
Abstract: PURPOSE:To make the error coefficient data 0, and to decode the coefficient data which are not erroneous with respect to a valid block resulting from deciding the validity/invalidity of the block including the error coefficient data. CONSTITUTION:The coefficient data and an error flag are outputted from a variable-length code decoder 47 in order of a zigzag scanning. A counter 52 counts the number of pieces of the coefficient data which are not erroneous by each block. The count value is compared with a threshold value by a comparator circuit 54. A threshold value generating circuit 53 receives an activity code AT to indicate the precision of the picture of the block, and generates a threshold value corresponding to the precision. When the number of pieces of the coefficient data which are not erroneous is more than the threshold value, the valid block is decided. Then, the coefficient data which are erroneous are forcedly turned to 0 in the valid block by a control signal CONT from the comparator circuit 54. Afterwards, the coefficient data are inverse- transformed by an inverse DCT circuit 50.

Title: Pulse signal input circuit
Inventor: KANO SHUNSUKE
IPC: H03K5/08
Filed: 1987-12-08
Abstract: PURPOSE:To obtain square wave output distortionless in pulse width by adding a prescribed voltage on a pulse input signal whose rise and fall are sluggish at the time of rising, and subtracting the prescribed voltage from it at the time of falling. CONSTITUTION:A signal voltage control circuit 10 which controls the prescribed voltage is provided on the input terminal of a comparator 2, and a capacitor 11 connected in parallel with an input resistor 3 via two diodes 12 and 13 being connected in antiparallel between the signal input terminal of the comparator 2 and a reference voltage input terminal is charged by the reference voltage of the comparator 2. Therefore, a charging voltage functions so that it can be added on the input signal at the time of rising when the input signal is lower than the reference voltage of the comparator 2, and can be subtracted from the input signal at the time of falling when it is higher than the reference voltage. Thereby, the voltage exceeds the reference voltage in early stages at the time of rise of the input signal, and it goes less than the reference voltage comparatively slowly at the time of falling. In such a way, it is possible to obtain the square wave output with a few amount of distortion in the pulse width.
