Abstract: PURPOSE:To feed air hotter than the outside air in a tank to increase the drying efficiency, by providing a recycled blow-through means making use of a part of the exhaust air from the tank or the whole thereof as the recycling air into the tank. CONSTITUTION:In a dish washer and dryer, washing liquid or water retained in a water storage tank 4 is sucked by a washing pump 3 and jetted from a nozzle 5 to force the water to collide with dishes in order to wash and rinse the dishes. After completion of discharge of water, the dishes are dried by an air-feeding fan 8. In this drying process, the outside air sucked from an air suction opening 9 by the fan 8 is blown from a blow-through opening 11 into the tank 2 through an air suction duct 10 and heated by a heater 6. In this case, a discharge opening for mixing air is opened at the top of the tank as a recycled blow-through means 15 and connected to the air suction duct 10 through a mixing air duct provided with a valve as a variable means of the mixing ratio. In this way, the exhaust air from the tank through the discharge opening can be reused as the recycled blow-through air and hence the drying efficiency is increased.

Title: Mass flow meter
Inventor: KOIDO HIROSHI
IPC: G01F1/84
Filed: 1990-11-30
Abstract: PURPOSE:To judge the breakage of sensor tubes or the residence of bubbles in the tubes by detecting the abnormal vibration of the sensor tubes with an amplitude monitoring circuit and detecting the flexible condition of a case with distortional gauges. CONSTITUTION:When bubbles are mixed into sensor tubes 5, 6 or cracks occur in the tubes 5, 6, a resonant condition is disturbed and abnormal vibration occurs likewise. So, an amplitude monitoring circuit 31 inputs a signal from an integrating circuit 30 where velocity voltage is converted into amplitude voltage to monitor the abnormality of amplitude, and outputs an amplitude abnormal signal (a) when input amplitude voltage V is not higher than reference voltage Vret. A control circuit 23 inputs a signal (a) from the circuit 31 via a V-F conversion circuit 21 and inputs a signal from distortional gauges 14, 15 which are adhered to the inner wall of a cover 1A because judgement can not be made whether bubbles reside or the tubes 5, 6 are broken only through the signal (a), and displays abnormal items after selected in combination of change in the vibration frequencies of the tubes 5, 6 and change in the resistance value of the gauges 14, 15.

Filed: 1994-12-29
Abstract: PURPOSE: To provide a LAN system capable of detecting and recognizing the faults of an inter-LAN repeater by providing an inter-LAN frame monitoring device which displays a frame which is to be relayed but not relayed. CONSTITUTION: All frames on lines 1, 2 are stored in the buffers 81, 51 of the inter-LAN frame monitoring device 80 connected to LAN lines 1, 2 in parallel with the inter-LAN repeater. The frame judged as a relayed frame is deleted from the buffers 81, 85 by comparing an opposite address and a transmission origin address with address tables 82, 86. In this way, the frame not being relayed due to the fault of the repeater is left as being held with the buffers 81, 85 on a transmitting line side. Such frame information is displayed on display parts 84, 88, and the fault of the repeater is detected. Therefore, it is possible to recognize the fact that the frame to be relayed from the repeater has been relayed correctly, which enables a quick countermeasure to be taken.
