Abstract: PURPOSE:To induce photomultiplier function effectively by using the simple substance or the compound of Zn or Cd as a diffusing source, forming a staircase type junction by thermal diffusion, covering the upper surface of an InP window layer with SiNX, performing heat treatment again, and changing the junction into a slant type junction. CONSTITUTION:An N<->-InP buffer layer 2, an N<->-InGaAs light receiving layer 3, an N-InGaAs intermediate layer 4, an N-InP multiplying layer 5, and an N<->-InP window layer 6 are sequentially grown as crystals on an N-type InP substrate 1. The entire surface of the InP window layer 6 is covered with SiNX 7. Thereafter, a doughnut pattern is formed by using photolithography. This element is put into a sealed ampule together with powder of CdP2. Thermal diffusion is performed for one hour at 550 deg.C. Then, the entire surface of the upper part of the N<->-InP window layer 6 is covered 7 again with SiNX. Thereafter, heat treatment is performed for 10 hours at 450 deg.C in vacuum. Then, the SiNX layer 7 is formed again on the upper part of the window layer 6. A main junction forming pattern is formed at the central part of the layer 7, as a diffusion mask. The specimen is put into a sealed ampule together with powder of ZnP2, and heat treatment is performed for 15 minutes at 550 deg.C.

Title: Pattern recognizing device
Inventor: KATO YUZO
IPC: G06K9/62
Filed: 1985-07-30
Abstract: PURPOSE:To have a learning function at the time of recognition by obtaining the sum of the number of times to pass through respective states in an order logic and the number of times to pass through a common state and extracting a characteristic. CONSTITUTION:In a device made by the correcting method of the order logic, when the number of skipping between states is one or below and the states to transit by the same code exist, the probability is high in which the number of times to pass through these states comes to be the characteristic having the linear sum rather than the individually stable characteristic. For example, in the condition transition diagram of the pattern '7,' the skipping number between states of a condition A1 and a condition a1 is 1, the condition is the one to transit by a code 3, and in the discrimination of the pattern '7' and the pattern 'WA' in KATAKANA (square form of Japanese syllabary), -7.6(X1+x1) can be obtained as the discrimination function. Here, X1 and x1 are the number of times to pass through the condition A1 and the condition a1 respectively. Thus they comes to be the characteristic of the discrimination.

Title: Decoding system for error correction block code
Inventor: URABE KENZO
IPC: G06F11/10
Filed: 1987-07-09
Abstract: PURPOSE:To increase the degree of freedom for setting the distribution rate of a mis-reception rate and a critical rate by deciding the acceptance/rejection of a decoded word output corresponding to the combination between an erroneous pattern and quality information. CONSTITUTION:An error pattern E consists of sets of error component ei of each component ri of a received word R and a quality information register 3 receives the quality information qi corresponding to each component ri of the received word, stores it and outputs the quality information Q. Then a critical region circuit 5 outputs A=1 (rejection) when the logical state of ei=0 (no error) and qi=1 (quality deterioration) takes place at least one symbol position (i) so as to detect the rejection condition due to the production of the quality deterioration information not included in the symbol location representing an error. Thus, either the rejection rate of the code or the mis- acceptance rate is set continuously in a prescribed range, and the degree of the freedom of the distribution rate setting of the both is improved.

Title: Variable length code decoder
Inventor: SAITO SATORU
IPC: H03M7/42
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a variable length code decoder which can decode the variable length codes at high speed. SOLUTION: A variable length code decoding part decodes the variable length codes out of a code bit string of the compressed image data and includes a code length detection part and a variable length code detection part. The code length detection part detects the code length by considering a code length table with respect to a variable length code bit string, and a variable length code detection part compares the variable length code corresponding to the code length detected by the code length detection part with all prescribed variable length codes and specifies a variable length code, to obtain the corresponding run level output (decoding data). The code length table of the code length detection part contains the correspondence between the code lengths' and the minimum bit strings (code length detection entries) which are common among variable length codes of the same length.  The number of common minimum bit strings necessary for specification of the code length is much smaller than the number of prescribed variable length codes. As a result, the code length can be detected in an extremely short period, and the circuit scale is also reduced for detection of the code length.

Title: Formation of transfer image
Inventor: AOKI SUSUMU
IPC: G03G15/00
Filed: 1988-07-08
Abstract: PURPOSE:To attain a high density transfer image free from ground stain and to repeatedly obtain transfer images of the same density with high reproducibility by permitting a photopolymerization initiator used for a photopolymerizable component containing layer to contain at least one specific compound. CONSTITUTION:The photopolymerizable component containing layer contains the photopolymerization initiator shown by expression I, a photopolymerizable or photo-crosslinkable compd. having unsaturated bond, a binder, and a sensitizer, if necessary. In the expression, R1 and R2 represent hydrogen atom, alkyl group, alkoxyl group, dialkylamino group, or halogen atom, and may be the same or different. Through the use of the photopolymerization initiator, an electric resistance in an exposed area is great, and retains sufficiently high initial electric charges, whose attenuation rate is low. On the other hand, electric charges in an unexposed area speedily attenuate substantially to zero. Consequently, a high density transfer image free from ground stain can be obtained, and moreover transfer images of the same density can be repeatedly attained with high reproducibility, and can be used as color proof.
