摘要： PURPOSE:To enable efficient heating of a glass mask in a short time in prebaking and postbaking steps and deformation of a resist film pattern by irradiating IR rays from the reverse side to heat the glass mask. CONSTITUTION:The reverse side of a glass mask 1, that is, the reverse side of the glass base 2 on which a metallic film 3 is not attached is irradiated with near IR rays from a light source 5. The base 2, especially made of quartz, has high transmittance of said rays, and absorbs them not too much. The rays irradiated from the reverse side are transmitted through the base 2 and absorbed with the film 3 to selectively heat it. As a result, in prebaking and postbaking, efficient heating can be attained in a short time, resulting in sufficient baking only in 5-10min, thus permitting prevention of deformation of the pattern of the resist film 4 in the postbaking.

摘要： PURPOSE:To switch and use a linear polarized wave or a circular polarized wave in a state that a circular polarizer remains fixed to the radiation surface of a radar antenna device, by winding a tape which has joined a metallic tape and a low dielectric tape together in one tape by tape winders alternately. CONSTITUTION:A tape which has joined a metallic tape 3 and a low dielectric tape 4 in one tape at every its prescribed length is inserted into a groove part slotting part 8 of a low permittivity substance 1 which has been slotted like a lattice, through a roll 5 installed to the end, and both ends of the tape are connected to the side of tape winders 6, 7, respectively. When half of the tape is constituted of the metallic tape, the remaining half is constituted of the low dielectric tape, and the low dielectric tape is wound by the tape winder 6 so that the metallic tape 3 is stretched on the whole lattice sloting part 8, a transducer for a circular polarized wave is obtained, and on the contrary, when the metallic tape is wound by the winder 7, and the low dielectric tape 4 is stretched on the whole lattice slotting part 8, a linear polarized wave can be used.

摘要： PURPOSE:To reduce transmission lines by using one common transmission line and one transmission line for a power-on control signal and a power-on completion response signal, and another one transmission line for a power-off control signal and power-off completion response signal. CONSTITUTION:The power-on snap switch 32 of a high priority power source controller 31 is opened in power-on operation and the relay operating power source 34 on the side of a low priority deive 33 is connected to a power-on completion relay 43 through a power-on indication/completion line 35 and the common line 36. The power-off snap switch 44 is opened in power-off operation and a relay operation power source 34 is connected to a power-off relay 46 through a power-off indication/completion line 45 and a common line 36. When a power- source disconnection is made, the relay operating power source 42 is connected to a power-off completion relay 49 through the power-off indication/completion line 45 and common line 36.

摘要： PURPOSE:To prevent a switching element such as a thyristor from malfunctioning even a large noise is applied, by charging a capacitor with a constant current and operating the switching element by the voltage across the capacitor. CONSTITUTION:Once the voltage between +V and -V exceeds a rated voltage value, a constant voltage diode ZE conducts, and then a constant current diode 3 also conducts to output a constant current I0. Consequently, the capacitor C3 is charged with the constant current and the thyristor CR turns on a specific time t0 later to detect an overvoltage. Thus, the time until the thyristor CR turns on is made invariably constant by the constant current diode 3, so no malfunction caused by a noise occurs regardless of the level of the noise.
摘要翻译：目的：为了防止诸如晶闸管之类的开关元件发生故障，即使施加大的噪声，通过对恒流电容器充电，并通过电容器两端的电压来操作开关元件。构成：一旦+ V和-V之间的电压超过额定电压值，恒压二极管ZE导通，然后恒流二极管3也导通以输出恒定电流I0。因此，电容器C3以恒定电流充电，并且晶闸管CR稍后导通特定时间t0以检测过电压。因此，直到晶闸管CR接通的时间由恒定电流二极管3变得不变，所以不管噪声的水平如何，都不会产生由噪声引起的故障。
