Title: Multi-signal amplifier
Inventor: KAJIWARA NORIO
IPC: H03F3/20
Filed: 1990-02-28
Abstract: PURPOSE:To improve the power efficiency automatically while excellent linearity is maintained even when the number of input signals or the like is fluctuated due to a change in the operating state by varying a bias voltage to a power amplifier circuit in response to the number of the input signal. CONSTITUTION:A multi-signal led from an input terminal 1 is fed to an amplifier circuit 2 via a branching circuit 5 composed of a directional coupler. On the other hand, the multi-signal partly branched by the branching circuit 5 is fed to a detection circuit 6 applying peak detection, from which a peak detection voltage corresponding to the signal number fed thereto is outputted as an output voltage. A power supply circuit 7 is driven by a peak detection voltage with a level corresponding to the number of input signals to vary its bias supply voltage to other circuits, then the bias supply voltage is changed in response to the number of input signal waves. Thus, even when the number of operating signals is changed due to a change in the operating state of a communication equipment or the like, the reduction in the power efficiency is suppressed low.

Title: Waterproofing technique
Inventor: YUUKI TAKESHI
IPC: E04D11/02
Filed: 1982-03-24
Abstract: PURPOSE:To carry out waterproofing easily without deleterious change in working circumstances, by applying a water-base adhesive consisting mainly of an ethylene/vinyl ester copolymer dispersion onto one side of a ground such as concrete or plywood and pressing a waterproof sheet against the adhesive in a highly dried state. CONSTITUTION:A water-base adhesive consisting mainly of an aq. dispersion with a glass transition temp. of -5--40 deg.C, having 5-50wt% ethylene content and 95-50wt% vinyl ester (e.g., vinyl acetate, vinyl propionate) content is applied on one side of a ground comprising concrete or plywood, and a waterproof sheet (e.g., a sheet consisting mainly of ethylene/propylene/diene terpolymer) is pressed against the adhesive in a dryness of 40-100%. There is no fear of deleterious change in working circumstances caused by evaporation of solvents. When dried, waterproofing can be carried out in application onto only one side but not both sides, which are difficult to work, and also in a highly dried state.

Title: Two-cycle engine
Inventor: ABE SEIYUKI
IPC: F02B75/02
Filed: 1979-04-19
Abstract: PURPOSE: To improve intake efficiency and reduce fuel consumption and HC emissions, by applying a pump, which supplies air or a thin mixture under pressure, and another pump, which supplies a thick mixture of theoretical concentration or more under pressure, to an engine so that the top dead centers of these pumps do not coincide with each other as to time.  
     CONSTITUTION: A mixture of theoretical concentration or a thick mixture through a bore 35 and a check valve 31 and air or a thin mixture through a bore 36 and a check valve 32 are sucked into chambers M, A in which negative pressure is caused by pistons 37, 38 moving toward the bottom dead centers. Since the phase of the piston 38 precedes that of the other piston 37, the thin mixure first opens a valve 28 and then and proceeds and raises its pressure in a scavenged gas confluence chamber 5 whose exhaust port 3 is closed. The thick mixture first enters into a combustion cylinder 2 in which the pressure is reduced due to the discharge of exhaust gas through an exhaust port 4. At that time, the thin mixture performs scanvenging. After that, the thick mixture enters into the combustion cylinder. Efficient scavenging is thus enabled.

Title: Heat pipe
Inventor: OGATA JUNJI
IPC: F28D15/02
Filed: 1989-03-02
Abstract: PURPOSE:To improve heat transporting capacity by a method wherein a vapor flow passage and a pair of liquid flow passages, pinching the vapor flow passage, are formed in a continuous main body and both ends of these flow passages are communicated mutually through throats. CONSTITUTION:The liquid of operating medium absorbs heat in the vapor flow passage 2 of an evaporating unit 6 and is evaporated. Then, the vapor of the liquid flows through the vapor flow passage 2 and arrives at a condensing unit 7 whereat the vapor dissipates heat and is condensed. Liquid enters into liquid flow passages 3A, 3B through a peripheral group 8 and throats 4 and is diffused to the whole circumference by a peripheral group 9, then, flows through the liquid flow passages 3A, 3B to the evaporating unit 6 and returns into the vapor flow passage 2 through the peripheral group 9 and the throats 4 while the vapor is energized by the peripheral group 8 and is diffused to the whole circumference. Heat is transported continuously from the evaporating unit 6 to the condensing unit 7 by repeating above-described operations. According to this method, the shifting distance of the operating medium liquid in the evaporating unit 6 becomes about half compared with a heat pipe so far and, accordingly, friction loss may become about half and the supplying capacity of the operating medium liquid may be increased remarkably.

IPC: A61H9/00
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a biological wave treatment device capable of substantially mitigating using conditions without giving the unpleasant feelings of electric shock stimulation or the like. SOLUTION: A case 9 is provided with a cone 41 provided vibratably along an axial direction X and a yoke 42 and a head 43 arranged so as to hold the voice coil of a coil part 44 attached to the corn 41 in-between. Between the yoke 42 and the head 43, a magnetic field is formed so as to pass through a coil. When a DC current is bidirectionally supplied to the coil, force in a first axial direction X1 and in a second axial direction X2 alternately acts on the coil. As a result, the corn 41 is vibrated along the axial direction X. Thus, when the case 9 is brought closer to a lesion, wave treatment by an air pressure is executed to the lesion. Thus, since a current is not made to flow to a human body, the electric shock stimulation is not given, it is used for a heart part and a head part as well, and further, it is used even when moisture is present.
