Title: Frequency sweep type radar beacon device
Inventor: SUNAKAWA MITSURU
IPC: G01S13/75
Filed: 1982-04-14
Abstract: PURPOSE:To exactly execute a response operaton of a beacon, and also to make PPI display uniform and easily visible, by constituting a titled device so that it is reset to main and sub-sweep frequency schedules when sweep of receiving frequency is stopped, and a pulse is received for a specified period. CONSTITUTION:When sub-sweep crosses beacon receiving band width and the first radar pulse is received, a sweep level holding part 11 detects it through a continuous wave detecting part 12, temporarily cuts the connection with a sweep generating part 10, and holds a sweep level. Oscillation frequency of a local oscillator 8 is held. When the continuous wave detecting part 12 detects that the radar pulse is received continuously at prescribed intervals, the sweep level holding part 11 releases its holding and is connected with the sweep generating part 10.

Abstract: PURPOSE:To provide the liquid crystal display element which is easy to see and is improved in contrast by bringing a reflection plate into direct contact with one side of a macromolecule-liquid crystal composite. CONSTITUTION:This liquid crystal electrooptical element consists of the macromolecule-liquid crystal composite formed by dispersing and mixing of macromolecules 1-7 and liquid crystals 1-6, electrodes 1-4 arranged on both sides thereof and substrates 1-3. A reflection plate 1-9 comes into direct contact with one side of the macromolecule-liquid crystal composite. This reflection plate 1-9 is a metallic thin film or metallic compd. thin film formed on the substrate 1-3 ad is in common use as the electrode 1-4. The liquid crystal molecules orient in the direction of an electric field and dichromatic dye orients in the direction of the electric field as well when the electrode field is impressed to the pixel electrodes. The display state of the pixels is, therefore, changed from the coloring state by the absorption of the dichromatic dye when the electric field is not impressed to the clouding state that the liquid crystals 1-6 and the macromolecules 1-7 are scattered by the noncoincidence of the refractive indices thereof.

Title: Cool and hot environment tester
Inventor: SHINOHARA HIROMICHI
IPC: G01R31/26
Filed: 1988-03-18
Abstract: PURPOSE:To enable the extension of a time for a high-temperature test and an ordinary-temperature test and to lessen the capacity of a heater, by reducing the quantity of frost sticking to a cooler in a low-temperature bath and thereby to extend an interval of a defrosting time. CONSTITUTION:In the case of execution of a low-temperature test, a temperature in a low-temperature bath 2 is kept invariably to be lower by -10 deg.C than a test temperature. Since temperature is kept for a long time, water in the bath 2 congeals and sticks to a cooler 8 in the bath 2. With a time passing on, the outside air flows in through gaps of switching dampers 6 and 7 and the frost sticking to the cooler 8 increases. After some time, therefore, the cooler 8 must be stopped to remove the frost by a temperature-adjusting heater 9, and then the water is drained outside by opening a solenoid valve 24 on the occasion. Simultaneously with the end of defrosting, the valve 24 is closed and the cooler 8 is operated so that a prescribed temperature be obtained. This operation is repeated when some time passes further, and thereby a time for which the cooler 8 is not frosted can be made longer than in the case when a drain pipe is not provided with the valve 24.
