Filed: 1986-09-19
Abstract: PURPOSE:To surely protect a heater by stopping the supply of heating current to the heater by a comparing/controlling means when when the value of a difference signal is smaller than that of a signal corresponding to the heating current. CONSTITUTION:A temperature control circuit 21 compares a voltage signal obtained from a thermocouple 18 with a signal corresponding to a required set temperature in a sample room 11 and outputs a pulse train having a ratio of a high level to a low level corresponding to the difference of the signals. The pulse signal is supplied to a switch circuit 20 through a gate circuit 22. The circuit 22 supplies heating current from a power source 19 to the heater 14 when the supplied pulse signal is a high level, and at the time of its low level, stops the supply. Consequently the generated heat is proportional to the time width of the high level of the pulse and the temperature in the sample room 11 is held at a required value. Thus, the heater can be surely protected.

Title: Magnetic card
Inventor: MAKINO YOSHIAKI
IPC: G06K19/00
Filed: 1987-09-07
Abstract: PURPOSE:To prevent the unfair use of a magnetic card by having by providing a bar code shape fixed pattern having almost equal coercive force at room temperature, and composing of the plural types of magnetic substances to have respectively different coercive forces at the temperature to separate the room temperature. CONSTITUTION:For example, a fixed pattern 3 is unidirectional saturation- magnetized in a direct current saturation magnetic field (>=1,000Oe) nearby at the room temperature (20 deg.C). In such a condition, when the pattern is read by a magnetic head for reading, the signal of all '1' is detected. Next, in a condition the fixed pattern part 3 is heated at 60 deg.C, the erasing magnetic field of 300Oe is impressed in the reverse direction of a saturation-magnetized direction and the magnetization of the fixed pattern of a B magnetic substance part is erased. When the reading of the part of the fixed pattern 3 is executed by the reading magnetic head, a peculiar signal is generated. Thus, a forgerforms the same fixed pattern to the magnetic card with using one type of the magnetic substance, a forgery can be immediately discriminated since the output of a peculiar code is not generated.
