Patent JP-S60231323-A (JP)
Title: Electron beam drawing apparatus
Inventor: YOSHIOKA NOBUYUKI
IPC: H01J37/305
Filed: 1984-04-27
Abstract: PURPOSE:To enable a small-sized apparatus to effect drawing on a wafer which is placed in the atmosphere, by partitioning a vacuum vessel and the atmosphere from each other by means of a thin-film window made of a material which transmits an electron beam, and applying an electron beam to a wafer placed near this window from the vacuum vessel side. CONSTITUTION:An organic thin film 5 made of, e.g., polyimide, and having a diameter of about 1mm. and a thickness of 2-3mum is stretched at the lower end of a vacuum vessel 4. The inside E of the vessel 4 is evacuated to a high vacuum. The distance (h) betwen the thin film 5 and a wafer 3 is held at about 10mum. Since the area of the thin film 5 is small, there is no fear of the film 5 being broken even when placed between a vacuum and the atmosphere and thereby subjected to a pressure. An electron beam 1 with an accelerating voltage of 50-100kV is applied toward the wafer 3 from the vacuum vessel 4 side of the apparatus held in this state. The electron beam 1 passes through the thin film 5 and the atmosphere with a thickness (h) without substantially scattering and is incident on the wafer 3. As a result, electron beam drawing can be effected on the wafer 3 which is placed in the atmosphere.

Title: Refuge guiding system at time of disaster for building utilizing heliotropism
Inventor: KUBOTA KATSUAKI
IPC: G08B5/00
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To improve reliability at the time of refuge guidance, to reduce installation costs and to provide a system, which can be easily installed at an existing building as well, by arranging the door of see-through glass and a fire prevention door and increasing the wall surface luminance of a refuge route to be watched by a refugee, in the order of a living room, passageway and stairs. SOLUTION: An exit 3 from a living room 1 has no door for recognizing lightness or is composed of a glass door or a glass fire prevention door on a fire prevention zone. Besides, at the time of disaster occurrence caused by a fire, the wall surface luminance of the refuge route watched by refugees is increased in the order of the living room 1, passageway 2 and stairs 4. This wall surface luminance is controlled through a controller interlocked with a smoke sensor installed indoors. Thus, when the refugee takes refuge, since the luminance of an opening part to a much safer space is increased rather than luminance around the opening part of a current space where the refugee stays, while utilizing the heliotropism as a human activity at the time of refuge, the refuge guidance is performed in order.

Title: Remaining quantity detector of toner for electrophotographic copier
Inventor: KOBAYASHI KUNJIYOU
IPC: G03G15/08
Filed: 1978-07-24
Abstract: PURPOSE:To detect the remaining quantity of toner when it becomes lower than reference by providing ultrasonic wave transmitting and receiving elements in a supply vessel, detecting the output of the ultrasonic wave receiving element and deteting the level. CONSTITUTION:Ultrasonic wave tansmitting and receiving elements 10, 13 are repectively constituted by both-end-open sound conducting pipes 8, 11 and transmitting and receiving microphones 9, 12, which are disposed in V-form in a supply vessel. Now, when the openings of the ends of the sound conducting pipes are buried in toner 17, the sound wave signal emitted from the transmitting microphone 9 is attenuated in the toner and the signal entering the microphone 12 is extremely weak. In contrast with this, when the openings of the sound conducting pipe ends expose from the toner surface, the sound wave signal reflects on the toner surface and becomes strong signal. Hence it is possible to detect that the remaining quantity of the toner has become lower than the reference quantity depending upon whether the sound wave signal is strong or weak and emit the signal urging its replenishment.
