Title: Controller of dot matrix type printer
Inventor: KAWAURA MASAAKI
IPC: B41J2/30
Filed: 1988-02-05
Abstract: PURPOSE:To perform an optimum heat radiating operation to all dot data without impairing a heat radiation effect after detecting heat generation of a printing head, by a method wherein the title controller of a dot matrix type printer is so constructed as to select either printing operation by judgement of a judgement means or printing operation of only a carriage per each one line travel motion. CONSTITUTION:In a CPU1, an addition means B successively adds the number of dots to be printed following to printing operation of a printing head 10, and a subtraction means 15 subtracts a constant value from a sum every time a time measuring means 14 measuring always time measures a constant time. Then, after completion of printing operation of one line content by a printing control means 17, a judgement means 16 judges whether the sum is not more than a fixed value. When the fixed value is exceeded, only a carriage is travelled without making a printing head 10 perform printing operation. Every time the travel motion of one line content ends, the judgement means 16 judges whether a count is not more than a reference value. When it becomes not more than the reference value, ordinary printing operation is started again.

Title: Printer
Inventor: TOKUHAMA NOBUTAKA
IPC: B41J33/14
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To protect an ink ribbon against breakage or damage. SOLUTION: When the moving direction of a carriage 5 mounting a print head 4 coincides with the feeding direction of an ink ribbon 8, a clutch 23 is connected to transmit power to an ink ribbon driving section 14 thus traveling the ink ribbon 8. When the moving direction of the carriage 5 is different from the feeding direction of the ink ribbon 8, the clutch 23 is disconnected to interrupt transmission of power to the ink ribbon driving section 14 thus stopping the ink ribbon 8. Since relative speed between the print head 4 mounted on the carriage 5 and the ink ribbon 8 does not increase, the ink ribbon 8 is protected against breakage or damage.

The material under analysis is contained into a cell, which sufficiently transmits the light and made to be a sensor part 41. The sensor part 41 is inserted between the half mirror 10 and the selector 15. The emitted light 17 from the spectroscope 16 is received with a photodetector 18 and converted into an electric signal 19. The signal is amplified with an electric amplifier 20 and the electric output is obtained. The spectrum data of the sample light and the contrast light are obtained and processed.

Filed: 1983-02-21
Abstract: PURPOSE:To shift accurately a spot by an amount equivalent to one track without receiving the effect due to the eccentricity of a disk, the variance of the track pitch, etc. CONSTITUTION:The tracking error control signal and the envelope signal receive waveform shapings (f) and (g) through comparators 23 and 21 on the basis of the OV level and are supplied to an objective position detecting circuit 22. The leading edge of a signal shown in the figure (h) corresponds to a fact that a spot reaches approximately at the center between a track N and a track (N+1) which is adjacent to the outer circumference side of the track N. Then a controller 18 delivers a command to a 1-track jump signal generating circuit 19 by the signal (h) to stop the generation of the 1-track jump signal. Thus the generation of a switch signal is also discontinued.
