Title: Long time pressing prevention unit in press-to-talk radio communication
Inventor: KAWAI TSUTOMU
IPC: H04B1/04
Filed: 1979-01-08
Abstract: PURPOSE:To automatically stop the radiation of electromagnetic waves from the radio unit for the long time pressing, by judgement whether the press operation with the press-to-talk switch is a transient long time pressing required or other long time pressing. CONSTITUTION:The capacitor C of the detection circuit 1 is charged to the power supply voltage at all times. If the press-to-talk switch SW is closed in a short time, the discharge voltage of the capacitor C is not decreased to the start voltage of the first timer circuit 3. Accordingly, the transistor TR is ON. When the switch SW is long closed, the terminal voltage across the capacitor C is lowered to the voltage starting the timer circuit 3. After the start of the timer circuit 3, FF circuit 6 is set after the delay time of the delay circuit 4 and the transistor TR is not turned on.

Title: Thermal transfer ink film
Inventor: HATTORI SHINTARO
IPC: B41J31/00
Filed: 1987-01-09
Abstract: PURPOSE:To enable repeated use of film without degradation of printed image quality by providing a microcapsule containing dye in an ink layer on a base, and setting the glass transition point of a coating material within the range of ink layer temperatures at the time of thermal transfer printing. CONSTITUTION:During nonthermal transfer printing, the coat temperature of a microcapsule 3 is below a glass transition point (Tg) of a polymer material which constitutes a coat. Therefore, dye does not spread in the coat and subsequently, it is not supplied to an ink layer 4. In the meantime, during thermal transfer printing, the amount of dye corresponding to an increase in the temperature of the ink layer evaporates, moving to an image receiving paper. This results in a decrease in the amount of dye contained in the ink layer 4. At that time, if a material constituting the coat of the microcapsule 3 is so selected that the Tg of the material may stay within the range of temperatures of the ink layer 4 during thermal transfer printing, the dye spreads easily in the coat, permitting the dye to be supplied to the ink layer 4. Subsequently, the amount of dye contained in the ink layer 4 becomes constant regardless of shading of a thermal transfer image. For this reason, an image with a gradation can be repeatedly printed by means of thermal transfer.
