Title: Partial ignition detecting method in solvent recovery apparatus
Inventor: KAMETAKA ATSUSHI
IPC: B01D53/02
Filed: 1980-02-05
Abstract: PURPOSE: To detect partial ignition and effectively run an adsorption tank and prevent its explosion by measuring the change in the concn. of the specific gas in the exhaust gas emitting from the adsorption tank in recovering solvents including ketones from the exhaust gas by means of activated carbon.  
     CONSTITUTION: An exhaust gas contg. solvents such as ketones (e.g.; MEK) is supplied 14 to an adsorption tank 10, and after it is adsorbed off of the solvents by activated carbon 12, it is exhausted 16. In this case, a CO detector or CO 2  detector is connected to a desorbed gas exhaust pipe 16, and the change in the concn. of CO or CO 2  in the exhaust gas is continuously measured. If it detects the point where the concn. of, for example, CO, changes sharply, that is, the state likely to cause partial ignition, it emits a detection alarm. This detection signal is used for the operation of an alarm device or for the operation of a submerging device 46. As a result, the accuracy of detecting the occurrence of partial ignition is improved and the outbreak of disasters is prevented; moreover, the operating efficiency of the recovery apparatus is improved.

Title: Obstruction warning device for level crossing
Inventor: KUMADA YOSHIYUKI
IPC: B61L29/30
Filed: 1989-01-21
Abstract: PURPOSE:To obtain the title device of high in reliability as well as compact and lightweight by providing a main circuit checkout means for outputting check signals into a main circuit periodically to detect the abnormality of the main circuit. CONSTITUTION:A core breakdown detecting means 4 normally feeds core breakdown detecting signals into a flame tube 3, for instance, minute current to the extent of not igniting the flame tube 3. When the current becomes zero, the detecting means 4 judges the flame tube 3 to be ignited or in core breakdown, and that information is indicated on a display means 5. In addition, a main circuit checkout means 6 outputs check signals, for instance, pulse current every fixed time. In this case, the ignition circuit of the main circuit 2 is in action, but the output to the flame tube 3 becomes zero instantaneously, and thus the flame tube 3 is prevented from igniting. In case circuit abnormality such as the breaking of circuit forming components exists in a main circuit 2 itself, the abnormality is detected by the checkout means 6 and that effect is indicated on the display mans 5.

Title: Thermal printer
Inventor: ASAKURA OSAMU
IPC: G06K15/10
Filed: 1982-01-29
Abstract: PURPOSE:To reduce irregularity in printed density, by a method wherein heating elements provided at a thermal head of a thermal printer are preheated to maintain the  temperature of the element at a fixed value. CONSTITUTION:When a carriage 200 starts moving and the movement becomes substantially stable, a preheating current-passing pulse 202b having less power than that  of printing current-passing pulse 202a is impressed on the thermal head at the moment  a several-dot period before the start of the first printing 203 (printing of a part of letter H). Since the impressing of the pulse 202b results in heating only to a temperature of not higher than the melting point of a heat-fusible ink provided on a heat  transfer ribbon, printing is not conducted. when the passing of an electric current for  preheating is continued, a printing starting temperature 204c becomes constant. Once  the thermal head reaches an equilibrium, the maximum temperature 204d of the heating element at the time of passing an electric current for printing becomes constant,  so that no irregularity is generated in the printed density. In addition, when a continuous dot printing operation is conducted, the current-passing duration of the second  and later current-passing pulses 202c for continuous printing is set to be 80% of that  of the first printing current-passing pulse 202a, so that accumulation of heat in the heating element at the time of continuously passing an electric current is prevented.
