Title: Production of thermal head
Inventor: HASEBE NORIYUKI
IPC: B41J2/335
Filed: 1989-01-11
Abstract: PURPOSE:To enhance efficiency of heat transfer and contact of a head with a thermal recording paper by a method wherein a conductor pattern formed on an insulating substrate by use of a metal-organic paste is buried into the substrate through diffusion by a high-temperature heat treatment, and a heat generating resistor is formed on the conductor pattern by a thin film method. CONSTITUTION:Conductor patterns 31 are provided on an insulating substrate 11 by applying a metal-organic paste by printing and baking the applied paste. Then, a high-temperature heat treatment is conducted for interdiffusion of the materials of the substrate 11 and the conductor patterns 31, thereby burying the patterns 31 into the substrate 11. Thus, the upper surfaces of the substrate 11 and the conductor patterns 31 become substantially flush with each other, so that a heat generating resistor 2 formed thereon by a thin film method has a smooth upper surface, and a protective film 4 provided thereon has no recessed parts. Since the area of thermal contact of the resistor 2 with the conductor patterns 31 is small and the patterns 31 are small in thickness and heat capacity, the heat generated by the resistor 2 is mostly transferred to the protective film 4. The protective film 4, having no recessed parts, can transfer the heat effectively to a thermal recording paper 6. In addition, favorable contact between the protective film 4 and the paper 6 is ensured.

Title: Original reader
Inventor: ISHIKAWA KIYOTAKA
IPC: H04N1/04
Filed: 1984-01-12
Abstract: PURPOSE:To prevent deterioration of a reproduced picture by detecting a read speed at a scanning time of an original read part, deciding skip-read and overlap-read and by storing information. CONSTITUTION:An original reader causes an original read part 3 to start traveling when a travel start command is given, and at the same time the light is irradiated on a platen 1 by exposure lamps 3a and 3b. The reader makes a light- emitting element of a sensor 22 irradiate the light on a position marker 23, and outputs a p8lse signal P from the sensor 22 at a constant interval. The reader decides this signal P by its decision part 4,and when the reader outputs a read permission signal R, the reader stores the information to be read by photoelectric converter 3f in a buffer memory 9b in order. When pulse signals P4 and P5 becomes short in their periods the reader decides them to be skip-read and therefore does not output the read permission signal R corresponding to the signal P5. When a pulse signal P6 is outputted, the reader outputs the signal R4 because the periods of the signals P5 and P6 are restored to the permissible values, thus preventing the slipping off of the reproduced picture.

Title: Decoder of bch code
Inventor: INOUE TOORU
IPC: H03M13/00
Filed: 1983-01-14
Abstract: PURPOSE:To correct up to two errors on using the decoder for error correction by decoding a BCH code generated by a specifically formed polynomial to provide a detecting capability more excellent than that of a CRC. CONSTITUTION:The BCH code generated from the generator polynomial as G2(X)=1+X+X<5>+X<6>+X<8>+X<9>+X<10>+X<11>+X<13>+X<14>+X<16> where the code length (n) is in the range of <=257 bits. A signal inputted from a receiving input terminal 1 is divided by a division circuit comprising one-bit shift registers Q1-Q16. The value stored in the shift registers is inputted to an AND gate A. Thus, ''1'' is outputted from an output terminal 2 when an error is detected and ''0'' is outputted therefrom when not detected. In this case, since the decoding is in accordance with Equation G2(X), the minimum distance (d) is given as d=5 while a check bit of 16-bit is given. Thus, when the code is used as the error detecting code, optional random error up to 4-bit is detected and up to two errors are corrected.
