Title: Device for reinforcing suspended boiler
Inventor: NAKAO YOSHITOMO
IPC: F22B37/24
Filed: 1978-02-01
Abstract: PURPOSE: To make the structure economic without enlarging stoppers, by providing a male or female stopper with a part whose horizontal rigidity is low and thereby causing a plastic strain hysteresis to raise the vibration-damping effect.  
     CONSTITUTION: The male stopper 12, both the ends of which are fixed to strong iron members 4 of the frame of the boiler, is interposed between the female stoppers 1, each of which is fixed at only one end to a strong back stay 6 of the main body of the boiler. The cross section of the central part of the male stopper 12 is made smaller so that the horizontal rigidity of the central part is reduced. When a relative displacement is caused between the boiler body and the frame due to vibration, the male and the femals stoppers 1, 2 come into contact with each other and a reaction is caused. At that time, the central part of the stopper 12 is elastically and plastically deformed to absorb the kinetic energy to damp the vibration. Therefore, the  earthquake-proof property of the boiler frame is raised.

Title: Composite thyristor circuit
Inventor: YOSHINO TETSUO
IPC: H03K17/73
Filed: 1978-01-31
Abstract: PURPOSE:To stabilize thyristor by the procedure in which the equivalent parallel  capacity of thyristor is increased transitionally only when the change rate dv/dt of  applied voltage is great, and the current resulting from the applied voltage is flowed sideways. CONSTITUTION:When the value of dv/dt is great and the transistor 31 reaches an active zone, a collector current flows in the transistor and thus I1 = (1 + hFE)iC results. When the hFE of the transistor is set up to hFE>>1, the current I1 flowing in the thyristor 35 according to the dv/dt of applied voltage becomes hFE times as much as the current flowing in the condenser 33, resulting in the insertion of electrostatic capacity of equivalently hFE times in parallel with thyristor. Thus, this circuit enables one to suppress the dv/dt effect of thyristor by flowing sideways current resulting from applied voltage without causing the deterioration of the sensibility of AC impedance gate in the OFF state.

Title: Combustion device for liquid fuel
Inventor: ABE SATOSHI
IPC: F23Q25/00
Filed: 1980-01-31
Abstract: PURPOSE: To enhance extinguishing performance by providing an engaging mechanism which engages only when a wick is moved upward so that the wick can be lowered rapidly without being influenced by a driving motor or the like.  
     CONSTITUTION: For extinguishment, a main switch (not shown) is turned off, whereby the electric charge stored in a capacitor 61 is permitted to flow into a solenoid 58 to excite the latter. As a result, a plunger 59 is attracted so as to rotate a release lever 55 counterclockwise, thereby pushing the left end of a clutch lever 43 upward and rotating the lever 43 clockwise around a supporting shaft 44. The rotation of the lever 43 releases a stopper piece 42 from a ratchet 41, thereby enabling a rotary shaft 20 to rotate freely. Accordingly, the wick 15 moves downward rapidly while reversely rotating the shaft 20, as well as a ratchet wheel 37 and the ratchet 41 which are made to one body with the shaft 20, through a rack 18 and a pinion 21 under its own weight including the weights of a wick holder 17 and the like.

Title: Antibacterial self-leveling material
Inventor: WAKASUGI MIKIO
IPC: A61L2/16
Filed: 1998-01-22
Abstract: PROBLEM TO BE SOLVED: To enhance the antibacterial agent efficiency of antibacterial self-leveling material by compounding inorganic compound powder having the antibacterial property of specified specific gravity and specific average particle diameter. SOLUTION: Inorgnaic compound powder of specific gravity of 2.6 or lower and an average particle diameter of 20 μm or less is compounded in self leveling material. The specific gravities of cement and aggregate compounded in the self-leveling material, for example, are about 3.15 and about 2.6 respectively, the inorganic compound powder of lower specific gravity than these of cement and aggregate is more easy to float than the cement and the aggregate by bleeding after placing the self leveling material, as a result, it is easily concentrated in a surface layer part, and a contact area between the inorganic compound powder and a contaminant increases to improve action efficiency.  In addition, when the average particle diameter of the inorganic compound powder is 20 μm or less and less than the average particle diameters of the cement and the aggregate, it is easy to float smoothly in the surface layer part of the self leveling material during bleeding. Thereby growth of bacteria and microorganisms which are apt to adhere the surface layer part is prevented and the surface layer part is made antibacterial.

Title: Image forming device
Inventor: NAOI HIROO
IPC: G03G15/16
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device in which the occurrence of an electrification memory of positive polarity by the electrification charge of a recording material on a photoreceptor surface specially using an organic photoreceptor is surely and easily prevented in the case where a photoreceptive drum stops driving during forming an image. SOLUTION: It is assumed that the rotating of the photoreceptive drum 2 and the transfer operation of a transfer electrifying unit 7a are stopped because an abnormality is caused at the image forming device at time T4. A resistance factor for the photoreceptive drum 2 obtained at normally operating time is read from a RAM 10B by an idle rotation detecting unit 3b, so that an idle rotation quantity is detected with the kinetic energy of the photoreceptive drum 2 when the abnormality is caused.  Time (T5-T4) required for the photoreceptive drum 2 to idly rotate from a position at which it is opposed to the transfer electrifying unit 7a to the position at which it is opposed to a peeling electrifying unit 8a is decided by using the idle rotation quantity at a controlling part 11, so that the peeling electrifying unit 8a is set in a turn- off state by delaying by the portion of the time after when the abnormality is caused.

Title: Controller for electric vehicle
Inventor: UEDA HIROMITSU
IPC: B60L7/06
Filed: 1994-02-02
Abstract: PURPOSE:To realize a generative brake control positively by throwing a generative brake interrupter with a predetermined time lag upon delivery of a gate start command for generative brake control to a power converter thereby suppressing the voltage drop across a filter capacitor at the start of generative brake operation. CONSTITUTION:When a generative brake interrupter 15 is thrown in, a filter capacitor 12 is conventionally discharged through a generative brake resistor 16. Since the power being fed from a stringing is delayed through a filter reactor 4, voltage across the filter capacitor 12 drops temporarily and an undervoltage protective circuit functions to interrupt the main circuit. The generative brake interrupter 15 is thrown in with a time lag through the inventive controller and the filter capacitor 12 is charged with power from an inverter 17 at the time of starting generative brake operation. Consequently, the time lag due to the filter reactor is compensated for and the undervoltage protective operation 15 avoided resulting in a positive generative brake operation.

Abstract: PROBLEM TO BE SOLVED: To enable stable amplification, without impairing output characteristics or gain characteristics by interposing an RC parallel circuit in series between the input of an amplifier, which uses a high-frequency, large-output FET element and an input circuit for impedance matching and setting the K-factor of the amplifier in a specific frequency band above a specific value. SOLUTION: An RC parallel circuit 6 of a resistor 61 and a capacitor 62 is interpose between the input 51 of a transistor(TR) 5 as an amplifying element and the input circuit 3 for impedance matching in series with a signal line. An MESFET (metal-semiconductor field effect transistor) is used as a TR 5 for a necessary frequency of 1.5 GHz, and R=50Ω as the resistor 61 and C=33pF as the capacitor 62 are used. In this case, the K-factor is equal to or greater than 1 and is stable outside the required frequency band and <1 in the necessary frequency band, but there is no problem provided that the impedance of equipment connected to an input terminal 1 is 50Ω. Consequently, stable high-output power amplification can be performed without spoiling gain characteristics in the desired frequency band.
