Title: Abnormality detecting device in grain drying machine
Inventor: KOBAYASHI SHIGEO
IPC: F26B25/00
Filed: 1988-01-12
Abstract: PURPOSE:To detect not only an abnormal high temperature, generated by an airflow generating mechanism, but also an abnormal high temperature condition, generated by combustion in a burner itself, by a method wherein a duct for sending hot-air is provided so as to enter into the hot-air chamber of the frame of a grain drying machine while a temperature detector is provided above the duct through a communicating port. CONSTITUTION:When an induction fan 9 is stopped abnormally during drying operation, the flow of induced atmosphere is stagnated in a duct 44 without flowing through it and combustion flame rises upward; therefore, a temperature detector 48 detects it through a communicating port 49. When a predetermined range of safety has been exceeded, an abnormality information is delivered to a control unit, not shown in diagrams, the operations of the fuel pump 28 of a burner 6 and the fuel valve 29 for the same are stopped and grains in a drying machine are only circulated. When a hot-air temperature has risen abnormally or the burner 6 itself becomes abnormal and the burner 6 continues combustion under high-temperature condition, the temperature detector 48 detects it in the same manner; when the temperature of the hot-air chamber 8 shows abnormal condition, because of being positioned in the hot-air chamber 8, the temperature detector 48 outputs the abnormality information when the predetermined range of safety has been exceeded.

Title: Amplifier circuit
Inventor: KAMIMURA TAKUZOU
IPC: H03F3/20
Filed: 1984-01-14
Abstract: PURPOSE:To reduce the heating value at the time of no-signal and to set a proper current amplification factor by adding a constant current source to supply the minimum action current to a differential amplifier. CONSTITUTION:The base-emitter voltages of transistors TRs 48, 56 and 58 are set at V48, V56 and V58 respectively. While the forward voltage of a diode 44 is set at V44. Thus an output potential V0 which increases a drive current ID of a TR50 is equal to (V48-V44+V56-V58). Then a DC potential VCC/2 of an output point is equal to (V72+V44-V62-V56), where V62 is the base-emitter voltage of a TRs 62 and V72 and V74 are forward descending voltages of diodes 72 and 74respectively. Therefore the current ID is decided by (VCC/2-VX)/R64, where VX is the base potential of the TRs 56 and R64 is the value of a resistance 64. Then the potential VX is minimized to set the current ID at a minimum level at the time of no-signal. While the current ID is increased to reduce the current amplification factor of the TR50. In this way, the breakdown strength of an amplifier circuit is improved.
