Title: Photodiode
Inventor: KIYOHARA SHUICHI
IPC: H01L31/10
Filed: 1988-04-15
Abstract: PURPOSE:To reduce a junction capacitance and to enhance the performance by keeping a photodetecting area identical by a method wherein two or more pieces of either P-type semiconductors or N-type semiconductors are used and the two or more semiconductors are arranged in such a way that two or more corresponding depletion layers are continued individually. CONSTITUTION:P-type semiconductors 3, 4, 5, 6, 7 form a P-N junction together with an epitaxial layer 2 as an N-type semiconductor whose impurity concentration is small. A width L of a depletion layer 8 which is extended to the side of the epitaxial layer 2 is L {2epsilon(phi-V)Na/q.Nd(Na+Nd)}<1/2> when a dielectric constant of silicon is epsilon, a barrier potential difference of the P-N junction is phi, a bias voltage is V, a unit charge amount is q, an acceptor concentration in a P-region is Na and a donor concentration in an N-region is Nd. When an interval l between two of the P-type semiconductors 7 is set to l>=2L, the depletion layer 8 is continued; even a part where the P-type semiconductors do not exist can be used as an effective photodetecting face. Then, while the depletion layer 8 is kept sufficiently extended, an area of the P-type semiconductors can be reduced; accordingly, it is possible to reduce a junction capacitance without reducing a photodetecting area.

Abstract: 1378983 Digital data storage INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1972 [17 Nov 1971] 46161/72 Heading G4C Data are written on sequential tracks of a disc stack cylinder until a break point is reached, after which data are written on another disc stack or on sequential tracks of another cylinder of the same stack. In one embodiment having three disc packs each with 20 disc faces, each block of data in a string corresponds in length to one track on a disc. Assuming module 0 has a first available track at cylinder 2, face 5, the first 15 blocks of a string are recorded on faces 5-19 of cylinder 2 and the next 5 blocks of the string are recorded on cylinder 3 starting at face 0, for example. Blocks 20 are recorded in module 1, for example at first available cylinder 5 of faces 10-19 and cylinder 6 of faces 0-9. Similarly blocks 40-59 are recorded in module 2 at first available cylinder 1 of faces 4-19 and cylinder 2 of faces 0-3. This arrangement may require head movement for each group-of 20 blocks, depending on the location of the first available face in each module. In a second embodiment, blocks are recorded in succession on the first available faces in each module taken in turn and head movement only takes place if overflow from the last module occurs. Taking the same example as above, blocks 0-14 are recorded in module 0, cylinder 2, faces 5-19; blocks 15-24 in module 1, cylinder 5, faces 10-19; blocks 25-39 in module 2, cylinder 1, faces 4-18; block 40 in module 2, cylinder 1, face 19; blocks 41-59 would then be recorded in module 0, cylinder 3, faces 0-18. Algorithms for calculating the addresses of the various blocks in storage are described.

Abstract: PURPOSE: To determine an object binary signal and further to make it perfect to determine a visual field area end, by converting and correcting a binary coded signal that is not in a character area and expresses the character area, by providing a preprocessing circuit.  
     CONSTITUTION: A binary signal that corresponds to picture elements for one line is made agree with the memory capacity of shift register 5a in a preprocessing circuit and binary signals that correspond to picture elements for two lines and three lines are similarly made to agree with 5b, 5c..., thereby setting an array of (m) rows by (n) columns. To determine whether the binary signal of a block point is required, a mosaic-shaped pattern with components that correspond to picture elements of five rows by five columns centering on the binary signal corresponding to the object picture element is used. Additionally, picture elements for two columns per row, i.e. m+2 columns are electrically inserted (dymmy) and a binary signal line is so operated that there will be the picture element band of a background area of two columns. Then, a difference in pattern between the character area and background area is checked to determine picture elements at the end part accurately. Thus, it is made perfect to determine picture elements at the edge of the visual-field area.
