Title: Ion sensor
Inventor: ITO YOSHITAKA
IPC: G01N27/414
Filed: 1990-07-24
Abstract: PURPOSE:To reduce the drift of output voltage and to measure an ion stably and accurately against a temp. change by providing differential constitution using two ISFETs. CONSTITUTION:An ISFET 1 and a dummy metal electrode are sealed in an aqueous potassium chloride solution and this aqueous potassium chloride solution and a sample solution are brought to a contact state through a porous partition wall to set the FET 1 to a reference FET. An ISFET 2 is directly inserted in the sample solution to become an ion responsive FET and the differential output of two source potentials is read by source/follower circuit constitution of the FETs 1, 2. Since the gate membrane potential of the FET 1 is always constant and the gate membrane potential of the FET 2 changes corresponding to the ion activity of the sample solution, the difference between the gate membrane potentials of two FETs is taken out using the dummy electrode as a reference one. By this differential constitution, the drift of output voltage is lowered to a large extent and the output fluctuation due to the temp. change of the ISFETs can be eliminated and an ion can be stably and accurately measured.

Title: Manufacture of cathode-ray tube
Inventor: IKEBE KOICHI
IPC: H01J9/44
Filed: 1989-07-27
Abstract: PURPOSE:To avoid stray-emission and grid emission and obtain a good withstand voltage property by applying a positive voltage to an anode or grid electrode during an activating process, and stopping application of voltages to one part of the electrode. CONSTITUTION:A switch 7 is closed and an electric potential of about 300V is applied also to a second grid electrode 2 and an electron current 10 reaches the second grid electrode 2 as well as a third grid electrode 3 and starts to decompose barium oxide provided on the second grid electrode 2. Then, when the switch 7 is opened, the second grid electrode 2 maintains an electric potential of about 300V, the electrode 2 forming a condensor within a vacuum in cooperation with another electrode. Thus, without varying the flow of electrons, the electron current 10 is obtained only within the third grid electrode 2 and the action of decomposing barium oxide existing on the second grid electrode 2 is eliminated. This effect is continued unless the electric potential of another electrode is varied, and the electric potential of the second grid electrode 2 is not varied. A stable electron current 10 is thus obtained.

Title: Detection of cooling fan abnormality of thermal printer
Inventor: KATO ICHIRO
IPC: B41J2/32
Filed: 1988-08-05
Abstract: PURPOSE:To enable a stop of a cooling fan to be easily detected without establishing a specified stop detection sensor by a method wherein a control part measures on occasion initial temperature of a thermal had and temperature during printing from a temperature detection part, and compares increasing temperature calculated from the initial temperature and detection temperature with a specific value. CONSTITUTION:An MPU 4a reads initial temperature Ts and temperature Ti of a thermal head 1 from a temperature sensor 3 via an ADC 3a at a start of printing and stores respectively in a RAM 4c. Then, the MPU 4a compares the detected tempera ture Ti with established maximum temperature T max. Thereafter, when Ti> Tmax, printing interruption treatment is performed. When Ti<= Tmax contorary thereto, increasing temperature  To=Ti-Ts is calculated. Then, the increasing temperature Ti is compared with limit increasing temperature  Tmax. Then, when Ti > Tmax, printing is interrupted, and a fan alarm treatment is performed. When reversely  Ti<= Tmax, the MPU 4a a judges whether printing of one page ends or not. When printing does not end, the temperature Ti is measured again. Thus abnormality of a cooling state of a fan is detected, and erroneous operation caused by failure of the sensor can be also prevented.
