Title: Thermal shock test device
Inventor: HAYASHIDA TATSUO
IPC: G01N3/60
Filed: 1990-11-28
Abstract: PURPOSE:To enable reduction in refrigerating capacity due to return of oil to be avoided when the refrigerating capacity should be fully maximized by providing a pipe for returning oil for refluxing oil which is collected in an oil separator to a pipe at a suction side of a compressor. CONSTITUTION:When performing cooling operation in a low-temperature bath, cooling continues until a temperature sensor which is provided at a test chamber 1 detects a specified temperature after low-temperature switching dampers 6 and 7 are opened. Then, when it is detected that the test chamber 1 reaches a specified temperature by a temperature sensor, a heater 13 is started by that signal and air temperature is adjusted. An oil returning electromagnetic valve 55 is closed from a starting time of a low-temperature test (exposure) until a low-temperature exposure temperature is reached. Further, it is closed from a low-temperature exposure end point until a pre-cooling temperature is reached. These periods are the periods for fully utilizing the maximum refrigerating capacity for cooling the test chamber 1 or a low-temperature bath 2. By closing the oil-returning electromagnetic valve 55, refluxing of oil from an oil separator 26 to a suction side of a compressor 25 is stopped and reduction in performance of the compressor is avoided.

IPC: G09G1/14
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To obtain a horizontal drive signal whose tracking is matched at frequencies of all ranges by only adjusting once a deviation of frequency for one frequency. SOLUTION: In order to correct a frequency deviation of a horizontal drive signal 70 due to dispersion in components of a horizontal oscillation circuit 2, a level of a control voltage VFV outputted from an F/V conversion circuit 1 is changed when the horizontal drive signal 70 has a frequency, then a conversion characteristic changing means 11 changes a relation of a frequency fi of an input signal 50 converted into the control voltage VFV by the F/V conversion circuit 1 in matching with a relation between the control voltage VFV of the horizontal oscillation circuit 2 and the frequency fo of the horizontal drive signal 70.  Thus, the frequency deviation of the horizontal drive signal 70 is corrected without causing any tracking error over the entire frequency range by only correcting the frequency deviation of the horizontal drive signal 70 for one frequency of the horizontal drive signal 70.

Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To attain high speed level conversion without malfunction even at a low power supply voltage by connecting gates, drains and sources of P and N-channel FETs A-C and D-H to an input terminal and points of high and low level power supplies as specified. SOLUTION: P1-P3 and N1-N4 of P and N-channel FETs and a depletion TR ND 1 are connected to an input terminal 1 and points of high and low level power supplies as shown in figure, then the TRs N1, P3 act like normally on TRs. With the input terminal 1 set to 0V the N1 is conductive, then the P2, P1, ND1 are conductive, the N2 is nonconductive by the conductive P3, a level of a connecting point DOUT goes to 2.5V, the N3 is conductive and a level of an output terminal DOUT goes to 0V. With the terminal 1 set to 3.3V, the conductive N1 causes the P2 to be conductive because the level of the gate reaches nearly 1.2V, the P1 is nonconductive, the ND1 is conductive, the P3 is conductive because the source reaches 2.5V, and then the N2 is conductive. The output terminal DOUT goes to a level of 2.5V.  Thus, the circuit is not malfunctioned even at a low power supply voltage but operated stably and the level conversion time is reduced.
