Title: Thermal transfer recording medium
Inventor: SOGABE ATSUSHI
IPC: B41M5/30
Filed: 1992-10-26
Abstract: PURPOSE:To ensure the transfer properties of a hot-melt colored ink layer and to prevent the generation of trouble such as powder falling or planar release, in a thermal transfer recording medium wherein a hot-melt release layer and the hot-melt colored ink layer are laminated on a base material, by adding porous particles to the hot-melt release layer. CONSTITUTION:In a thermal transfer recording medium wherein a hot-melt release layer and a hot-melt colored ink layer are laminated on a base material in this order, porous particles are added to the hot-melt release layer. As a result, porous particles whose micropores are filled with air much remain in the release layer and, when the release layer is heated and melted at the time of printing, air in micropores expand to be discharged out of the particles and air bubbles are generated not only in the molten release layer but also in the interface with the base material. The contact area of the release layer and the base material in the heated part is reduced by the air bubbles and releasability is enhanced even when the melt viscosity of the release layer is high. The contact area is also reduced by the addition of particles to contribute to the enhancement of releasability.

IPC: H02M3/155
Filed: 1986-12-03
Abstract: PURPOSE:To prevent lowering of efficiency by detecting shortcircuiting of load from lowering of output voltage of a power source. CONSTITUTION:A switching power supply switches an input power Vi with a main transistor (hereinafter referred to as TR) TR0, smoothes a switching output voltage of said input power via reactor L0 and capacitor C0, and thereafter supplies said voltage as a given output voltage V0 to a load Z. A detector for short-circuiting of load is composed of resistor R01-R02 for dividing said output voltage V0, a comparator CP, a capacitor C1, a diode D1, a Zener diode ZD1 and auxiliary TR1-TR2. Further, the comparator CP forms a by-pass discharging path against a charging path for said capacitor C1 when its output voltage Vco is 'L', and the TR1 by-passes a baseemitter circuit for the main TR0 and turns OFF said main TR0 Thus, a given time passes after short circuiting of a load until the main TR0 will be turned OFF. Therefore, any malfunction of the detector can be prevented before establishment of the output voltage.

IPC: H04B1/59
Filed: 1991-11-05
Abstract: PURPOSE:To reduce the occurrence of radio countermeasures to external equipment and radio wave interference between adjacent systems by providing a transmitting power control means to an interrogator. CONSTITUTION:When a transmitting power controller 18 reads out the storing content of the memory of a responder, the read-out data are modulated by means of a reflection type modulator of the responder against a carrier transmitted from an interrogator 1 and reflected as response signals. The interrogator 1 receives the response signals through an antenna 13 and detects the signals by means of a detector 14, but the detecting level becomes higher as the response signals become larger and inversely proportional to the communication distance. Therefore, when the bias state of an oscillator or oscillating power amplifier circuit is controlled, the occurrence of radio countermeasures to external equipment and radio wave interference between adjacent systems can be minimized while required transmitting power is secured.
