Title: Dehumidifying dryer
Inventor: YAMADE KOICHI
IPC: F26B17/14
Filed: 1990-11-30
Abstract: PURPOSE:To enhance the drying efficiency of grain while eliminating the problem from the aspect of the quality of grain by adjusting the quantity of humidifying air to the first air passage on the basis of the detection data of a means for detecting the moisture of grain in a drying part. CONSTITUTION:The detection data obtained by a moisture detecting means 13 detecting the moisture of grain in a drying part A is inputted to a control means E which in turn controls the operation of dampers 24, 25 and the adjustment of the amount of dehumidifying air to the first air passage 17 on the basis of said data. When the state of stored grain is in a stage evading high temp. drying, the amount of the dehumidifying air flowing to the first air passage 17 is increased and the temp. of the dehumidifying air supplied to the drying part A can be lowered to a degree not bringing about the deterioration of grain. When the state of the stored grain becomes such a stage that the grain may be dried at high temp., the amount of the dehumidifying air flowing to the first air passage is suppressed and humidifying air is supplied to the drying part A to make it possible to enhance the drying efficiency or grain.

Filed: 1989-12-26
Abstract: PURPOSE:To sufficiently relieve stress in a silicon oxide film and the interface between the silicon oxide film and a silicon substrate, stabilize element characteristics like transistor characteristics, and form an element of high reliability, by annealing an impurity-introduced layer. CONSTITUTION:When stress generated in a silicon oxide film 2 and the interface between the film 2 and a silicon substrate 1 is relieved, the film 2 is firstly formed on the substrate 1 by, e.g. thermal oxidation, and a polysilicon layer 3 is formed on the film 2. Next, when an impurity-introduced layer 4 is formed on the layer 3, the layer 4 composed of WSi in which fluorine is introduced as impurity is formed, and then annealing is performed in an N2 gas atmosphere (an inert gas atmosphere is also applicable) at 1050 deg.C, for 30 minutes. A silicon oxide film 5 is formed on the layer 4 by, e.g. CVD method, and the film 5, the layer 4, and the layer 3 are patterned, thereby forming a gate electrode composed of the layer 4 and the layer 3. Hence the stress in the film 2 and the interface between the film 2 and the silicon substrate can be sufficiently relieved, so that element characteristics such as transistor characteristics are stabilized, and an element of high reliability can be formed.

Filed: 1994-12-29
Abstract: PURPOSE: To provide the hysteresis characteristic in an overvoltage detecting circuit, which detects whether each battery constituting a combined battery becomes the overvoltage state or not. CONSTITUTION: When the terminal voltage of any battery constituting a combined battery 1 exceeds the first voltage, an overvoltage detecting circuit 104 outputs the overvoltage detected-signal, and the entire charging currents supplied into the battery flow into bypass circuits 105. When the terminal voltage of the battery is decreased lower than the second voltage, which is lower than the first voltage, the overvoltage detecting circuit 104 stops the output of the overvoltage detected-signal, and the battery is charged again. The logic OR of the overvoltage detected-signal outputted from the respective overvoltage detecting circuits 104 is operated under the electrically insulated state to each other. A counting circuit 111 counts the number of times when the overvoltage detected-signals are outputted based on the result.  Then, a constant-current charging circuit 103 changes the amount of the charging current to be supplied into each battery in correspondence with the number of times so as to prevent the overcharge of each battery.
