Title: Fluorescent display tube
Inventor: KASAI ISAO
IPC: H05K1/18
Filed: 1982-07-06
Abstract: PURPOSE:To eliminate the living place of cockroaches by arranging so that infrared lights and visible lights do not leak to the print substrate side from the transparent body of a fluorescent display unit. CONSTITUTION:When a heater provided in a fluorescent display unit 1 for emitting electrons generates heat, infrared lights and visible lights are radiated, but by providing a reflector film 2 on the surface of a transparent body facing a print substrate 3, infrared lights and visible lights do not leak to the print substrate side 3 through the transparent body, thereby the temperature between the fluorescent display unit 1 and print substrate 3 can be made nearly the same as the outside temperature. Accordingly, cockroaches or the like can be prevented from living, breeding, or hibernating between the print substrate 3 and fluorescent display unit 1, thus the fluorescent display unit and electronic parts can be normally operated.

Filed: 1980-08-26
Abstract: PURPOSE:To form the magnet, which functions efficiently and is cheap, for a wire dot printer, etc. by forming a hole similar to a section of a core to a yoke member and pressing in and fixing the core to the hole. CONSTITUTION:A wire guide 11 and the holes 12, which are similar to the section of the core 10 and are slightly smaller than the core, are shaped to the bottom of the hollow cylindrical yoke 13.

Title: Interface device for communication terminal
Inventor: TAKEBAYASHI TOMOYOSHI
IPC: G06F13/00
Filed: 1992-05-11
Abstract: PURPOSE:To surely start data communication even when the preparation for communication takes much time by starting data communication terminals according to the reception commands in the form of voice signals and performing the voice notification of the operating state. CONSTITUTION:An incoming confirming means 20 extracts incoming commands from voice signals outputted from a voice communication interface 14. A data communication terminal starting means 22 starts a data communication terminal 16 by applying power when the reception of the power supply command is confirmed in case the incoming from a line 10 is confirmed. Then, a data communication terminal state detecting means 24 detects the operational state of the terminal 16, and a data communication terminal state notifying means 26 notifies the operational state of the terminal 16 to the incoming source when the reception of a state inquiring command is confirmed. Thus, the data communication can be started after confirming the communication reference by the terminal 16 is completed, resulting in starting the data communication without fail even when the access destination takes much time to prepare communication.
