Title: Ink jet recording device
Inventor: HOSAKA YASUO
IPC: B41J2/14
Filed: 1985-06-13
Abstract: PURPOSE:To eliminate clogging at an ink discharge outlet and to enable a satisfactory printing, by heating the ink of high viscosity around the tip of an ink jet nozzle and by reducing the viscosity. CONSTITUTION:A heating element 11 is provided in the vicinity of the tip of a nozzle 12. The heating element 11 is for heating an ink of a larger viscosity to reduce it; and the element is used for heating for about one second, and by raising the temperature of a wetting agent within the nozzle the ink with a high viscosity is changed to the ink with a reduced viscosity. If a pressure is applied in the direction of the arrow A, the ink is easily made to discharge from the nozzle and a clogging is eliminated. The viscosity reducing process is performed at the home position before the commencement of recording. The discharged ink not used is recovered for reuse.

Title: Exhaust method for electron tube
Inventor: TAKADA MICHIO
IPC: H01J9/385
Filed: 1980-09-16
Abstract: PURPOSE:To prevent perforation from being generated and improve workability and reliability by covering the circumference of a section where an exhaust tube is chipped off with a glass tube and chipping off the exhaust tube together with this glass tube. CONSTITUTION:When the exhaust tube for an electron tube, such as a cathode-ray tube, etc. is chipped off, a glass tube 14 is fit only to the circumference of a section 13 which is heated while an exhaust tube 12 formed on a glass stem 11 is being chipped off. When the exhaust tube 12 is heated and chipped off together with the glass tube 14, no suction is generated due to insufficiency of glass since the glass of the section 13 which is heated is thick. Thus even an exhaust tube with a thin glass can be prevented from being perforated. As a result, workability and reliability can be improved.

Title: Method for controlling printer apparatus
Inventor: YOSHIDA KINSUKE
IPC: B41J29/38
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To temporarily hold a paper during printing in a paper transfer path of a printer apparatus, by stopping the printer apparatus in a state as it is without ejecting the paper being printed if the printing operation is interrupted because of an error. SOLUTION: When transfer data are interrupted during printing, the printing is stopped and a paper transfer is stopped. Thereafter an alarm display is made at a liquid crystal display part B32, and also a buzzer B31 is sounded. In this state, the printer apparatus jams with the paper and an operator is required to remove the jamming paper. A data abnormality as a cause for the paper jam can thus be recognized and a cable, etc., is checked at this time when the paper in an abnormal state is to be printed again. The operator removes the jamming paper and executes a recovery operation such as a repair to a connection cable, confirmation, etc. A print command is resumed in the case of re-printing, or a printing work termination is instructed in the case where the printing is to be terminated.

Title: Dynamic viscoelasticity measuring instrument
Inventor: TAKEDA HARUO
IPC: G01N19/00
Filed: 1988-05-25
Abstract: PURPOSE:To execute an exact measurement by correcting a phase difference of a sample by a phase difference computing element from output signals of t1 and t2 measuring instruments, even if a zero crossing point output signal of a zero crossing detector is shifted due to a thermal expansion deformation of the sample. CONSTITUTION:When a distortion of a sine wave is given to a sample 1 from a distortion generator 2, stress having a phase difference of the same frequency as that of the distortion is generated in the sample 1. The stress of this sample 1is converted to an electric signal by a stress measuring instrument 4, and sent out to a zero crossing detector 5. When a signal from the measuring instrument 4 is brought to positive- negative inversion, this detector 5 outputs a zero crossing point signal to t1 and t2 measuring instruments 6, 7. Subsequently, the measuring instrument 6 measures the time t1 when the zero crossing point signal from the detector 5 is inputted, from the time point when a reference point signal of the distortion of the sine wave which has been given to the sample 1 by the generator 2 has been inputted from a timing circuit 3. Also, the measuring instrument 7 measures the time t2 to the next zero crossing point signal, from the zero crossing point signal of an output of the detector 5. In this state, in a phase difference computing element 8, an operation is executed by a signal from the measuring instruments 6, 7.
