Abstract: PURPOSE:To provide a surface treatment method of a substrate by a glow discharge plasma method under an atm. pressure with which gases for reaction and an inert gas are uniformly diffused and supplied to a plasma area, the use efficiency thereof is high and the amt. of the gases for reaction and inert gas is little. CONSTITUTION:On surface of a metallic electrode 4 is provided with a first solid dielectric substrate 6; a perforated metallic electrode 3 is disposed opposite to the firsts solid dielectric substance 6; the perforated metallic electrode 3 is formed to enable the supply of the gases for reaction and the inert gas and the space between the first solid dielectric substrate 6 and the perforated metallic electrode 3 is formed as the space, the side faces of which are covered with the second solid dielectric substance 8, by which a plasma generator is constituted. The substrate 7 is installed to the space of such plasma generator. The gases for reaction and the inert gas are supplied to the substrate 7 via the perforated metallic electrode 3. While the gases for reaction and the inert gas are made to flow to the peripheral part of the space described above from the inside of the space, glow discharge plasma is generated under the pressure near the atm. pressure and the excited active species are brought into contact with the surface of the substrate. As a result, the cost is reduced and handling is facilitated.

Title: Ice making method and apparatus in ice utilization equipment
Inventor: UDA MOTOHISA
IPC: F25C3/02
Filed: 1992-10-30
Abstract: PURPOSE:To make ice and capture the same properly and rapidly by cooling water to 0 deg.C or lower with low temperature air upon ice making in ice utilization equipment disposed inside or outside a house. CONSTITUTION:Air is converted to high temperature one by compressing the same into high pressure air (e.g. 2 atom), and the high temperature air is easily cooled to about ordinary temperature utilizing tap water temperature and fresh air temperature. Low temperature high pressure air is yielded by further cooling the ordinary temperature high pressure air with use of the low temperature air after passage thereof through an ice making cold air fan 4. Low temperature air at about -5 deg.C-about -45 deg.C is yielded by expanding the low temperature high pressure air using an expander 3. Ice making is achieved without causing any harmful environmental pollution by bringing the air at 0 deg.C or lower into direct contact with water droplets and a water screen flow. Further, an ice link and an ice course are constructed inside or outside a house by ventilating a cold air pipe buried in the ice link or the ice course with the cold air. Return air after passage through the cold air pipe can be recycled for compression, cooling, and expansion. Hereby, ice making and ice capture are properly and rapidly achieved.

Title: Signal transmitting system
Inventor: KIMURA KATSUHIKO
IPC: H04L25/49
Filed: 1992-11-25
Abstract: PURPOSE:To prevent a transmission error by applying a specific voltage in the off-duty period of a mark pulse. CONSTITUTION:The presence or the absence of the mark pulse in the first half part of one bit indicates a mark or a space. The off-duty period is provided on the latter half part of one bit. At the time of marking, the mark pulse has the polarity alternately switched and is transmitted. A certain voltage which has the same polarity as the mark pulse and is lower than the threshold on the reception side which identifies the mark pulse is applied in the off-duty period at the time of marking. The voltage variation for the fall of the mark pulse is reduced as much as possible, and an overshoot phenomenon to the opposite polarity due to a remaining DC component is made difficult to occur. Thus, the waveform distortion is reduced even in the case of a complicated transmission network to prevent the transmission error.
