Abstract: PURPOSE:To connect a plating on a printing surface part to a plain gauze body, by a method wherein a plain gauze surface of a plain gauze body on the side for constituting a printing surface is coated with an adhesive, a metal of plated substrate surface or the like is brought into contact with a metal of a printing surface part, and both them are subjected to plating to grow the printing surface part. CONSTITUTION:An epoxy resin adhesive 6 is applied to the surface of a soft rubber roller 7 in a thin film form, and the roller 7 is rolled several times on the plain gauze surface 3 to produce a uniform coated film. A coat layer 5 is determined by printing conditions, and the size thereof is preferably about 1/3 of the circumference of a plain gauze varn on the printing surface side. A wetted part is provided, a metallic powder 12 such as a copper powder or a silver powder is scattered or applied onto the wetted part, an excess of the powder 12 is removed, and the remainder is brought into contact with the surface of the substrate 1. While maintaining this contact condition, the assembly is subjected to plating by immersing it into a plating solution contained in a plating tank. The metallic powder 12 adhered to the surface of the adhesive 6 applied to the plain gauze yarn 15 conducts electricity to grow the plating, which becomes integral with the metal 2 of the printing surface part.

Abstract: PURPOSE:To select a difference from output frequencies of digital modulation signals optionally and to keep the difference constant with no adjustment by connecting electrically plural piezoelectric resonators and plural oscillation circuits one by one respectively. CONSTITUTION:The 1st and 2nd surface acoustic wave resonators 2, 3 comprising lots of electrode fingers are formed on a piezoelectric substrate 1, plural oscillation circuits 5, 6 are oscillated in a different frequency respectively in response to the resonance frequency of the resonators 2, 3 connected to the circuits 5, 6 and one of plural oscillated outputs is selected in response to the digital modulation signal at a changeover circuit 7 and the result is outputted. That is, a signal subject to FSK(frequency shift keying) modulation is outputted by the digital modulation signal. Since the change over circuit 7 follows the change in the digital input signal very fast because of a simple switching operation. Thus, plural frequencies of the outputted signal are set optionally and the interval of the frequencies is kept constant with no adjustment.

SOLUTION: When a ventilating and air supply means 2 passing through a partition structure 1 of a building for partitioning an indoor side A and an outdoor side B is driven by a motor 11 to rotate a propeller type impeller 12, air in the ceiling in the indoor side A is sucked to a wind channel 3 from the inlet port 5 of a grill 4, its direction is radially changed by a centrifugal diffuser air duct 8 and the air is radially exhausted from a discharge port 10. This exhaust air flow flows in a layer along the rear surface of the partition structure 1 and is exhausted outside via a ventilating port formed on the eaves part of the end side of the partition structure 1. When this exhaust air flow is formed, it cools the partition structure 1 and effectively suppresses heat radiation to the insdoor side,. even if the partition structure 1 undergoes the influence of insolation or hot air.

IPC: A47K3/02
Filed: 1990-03-13
Abstract: PURPOSE:To inform a user before undressing that a bath is not ready yet by a method wherein in a power failure, a sound generator is kept in action until a power source is energized again and a new bathing time is set. CONSTITUTION:When a power source 44 is turned on after power supply is restored, an initial setting is carried out and the bathing time set value is cleared. It is judged whether or not a new set bathing time value is set. In the case of NO, a buzzer driver 43 makes a buzzer 31 generate sound. This action is continued until a new set bathing time value is inputted. When the new bathing time is set, normal operation takes place and the buzzer 31 is stopped. Then, it is judged whether or not the present time is one hour before the set bathing time, and in the case of YES, the present water temperature Tw is detected and compared with the set water temperature Ts. When Tw>=Ts, a signal is outputted to turn on a circulation pump 12 and turn off an electric heater 3, and when Tw<=Ts, a signal is out put to turn on the circulation pump 12 and the electric heater 3 so that the water is heated up until the water temperature Tw reaches Ts.

Abstract: PURPOSE:To relieve a demand precision of a working pressure detector and to increase a combustion range TDR (rated maximum combustion flow rate/minimum combustion flow rate) under a condition that a detecting range output ratio is high, by controlling a gas pressure control valve with the aid of a pressure detector for detecting a difference in pressure between the upstream and the downstream of a variable throttle mechanism. CONSTITUTION:In case a combustion quantity is gradually choked from a rated maximum combustion condition, or, for example, when a hot water feed amount is reduced or if temperature of hot water is set to a low value, an electric signal from a temperature detector 7 or an electric signal from a temperature setting part 14 is compared for decision by a control operating part 15 to output it as a temperature deviation signal 16 to a variable throttle mechanism 4A. Thereafter, an operation is conducted so that the size of the flow path equivalent sectional area of the variable throttle mechanism 4A is gradually changed into a value opposing to the temperature deviation signal 16. Meanwhile, a value of a pressure detector 10 varies with a change in the value of the flow path equivalent sectional area to output an electric signal 17 which is processed as a control signal of a gas pressure control valve 3 by means of an electric control circuit 13.

Abstract: PURPOSE:To perform optimum controlling of immersion time in coloring liquid and uniformly color the surface of stainless steel by differentiating the secular change of the potential difference between the reference electrode and stainless steel in the coloring liquid by time, and controlling the slope of the differentiation curve thereof at the time of coloring the surface of the stainless steel. CONSTITUTION:Stainless steel 3 to be colored and a reference electrode 2 made of platinum are immersed in coloring liquid 1 consisting of a mixed aqueous soln. of chromic acid and sulfuric acid, whereby the surface of the stainless steel is subjected to coloring treatment. In this case, the potential difference generating across both electrodes 2 and 3 is measured at every 30-100sec with an mV meter 4, and the change of the potential difference with time is determined. With the slope alpha of the curve formed by differentiating said value by time as a change rate per unit time of a potential difference-time curve, arithmetic processing is performed rapidly. The point of time when the slope alpha switches from a decreasing tendency to an increasing tendency is made the coloring start point, and the potential difference change after this is correspondended to the change in coloring tone of the stainless steel. When it attains the preset value, the stainless steel is pulled from the coloring liquid, whereby it is uniformly colored.
