Title: Corrosion test
Inventor: MIYASHITA IZUMI
IPC: G01N27/02
Filed: 1986-04-23
Abstract: PURPOSE:To accurately and easily perform the corrosion test of a metal in a very short time by arranging a pair of metallic test pieces in a liquid at a prescribed space, applying an AC voltage across the test pieces and measuring the increasing rate of a flowing current for an elapsed time. CONSTITUTION:A pair of test pieces are made of a metallic material and dipped in an objective solution 2 as electrodes Ia and Ib. An impedance meter 3 is connected between the electrodes Ia and Ib and an impedance between the electrodes Ia and Ib is obtained from the AC power supply 4 and the ammeter 5 of the meter 3. Changes in the impedance are recorded in an X-Y recorder 6 and the changing rate of the impedance after a prescribed time is obtained. When the corrosion of a metal is severe, the increasing rate for time of an ion density in the solution is large and, accordingly, reduction in the impedance is extreme. Thus, by measuring changes in the impedance or in a flowing current, the corrosion resistance of the metallic material and the degree of the corrosivity of the solution can be obtained.

Title: Electric instantaneous water heater
Inventor: INABA MASANOSUKE
IPC: F24H9/18
Filed: 1984-05-09
Abstract: PURPOSE:To obtain an electric instantaneous water heater, which has high thermal efficiency and gives no shock of electricity, by a method wherein the secondary winding of a step-down transformer is also turned ON in response to the turning-ON of a tap so as to apply the secondary voltage of the transformer to an electric heating pipe connected in series on the upstream side of a tap pipe. CONSTITUTION:A step-down transformer 10 to transform high commercial supply voltage to low voltage of several volts, an electric heating pipe 20, which is connected in series on the upstream side of a tap 4 pipe and at the same time to which the secondary voltage of the transformer 10 is applied, and a switch to turn ON and OFF the primary winding of the transformer 10 in response to the turning-ON and -OFF of the tap 40 are provided. In other words, an electric instantaneous water heater, which has high thermal efficiency and is simple, can be obtained, because water flows directly through the electric heating pipe 20. In addition, no fear of being given the shock of electricity exists, because the voltage applied to the electric heating pipe is only several volts. Furthermore, because the whole electric heating pipe acts as a heat generating source, no fear of disconnection occurs even when a crack or the like develops on some portion of the electric heating pipe, resulting in facilitating the maintenance and management of the titled water heater.

Filed: 1978-07-27
Abstract: PURPOSE:To obtain optimum exposure, by applying reference exposure to a specified part of uniformly charged photosensitive drum, detecting the potential thereof in a image exposure position, and comparing this potential with the reference voltage to control the quantity of light of the exposure light source. CONSTITUTION:The entire surface of a photosensitive drum 1 is charged by a charger for charging 2, and only a potential detecting part 10, which is located at one side of the drum 1, is sequentially exposed by an auxiliary exposure lamp 3. When the potential detecting part 10 comes beneath a potential detector 5, the surface potential thereof is measured by the detector 5, and this potential signal is inputted into a control circuit 13 through an amplifier 12. Here, it is compared with the reference potential, i.e. the ideal potential of the potential detecting part 10 obtained by radiation of the auxiliary lamp 3 of specified 1ux.sec. If there is a potential difference from the surface potential of the detecting part 10 due to continuous use of electrophotographic copier or other reason, the voltage of an exposure lamp power source 14 is increased or decreased to correct this difference.

Title: Vessel of multi-component curable substance
Inventor: GUSUTAFU RANGU
IPC: E21D20/02
Filed: 1985-04-30
Abstract: A destructible container is arranged to maintain the components of a multi-component settable mass in separate regions until they are ready to be mixed for anchoring a fastener member in a borehole. The container is made up of an elongated outer cartridge and an inner cartridge positioned within the outer cartridge so that a space for one of the components is formed between the inner cartridge and the outer cartridge. The multi-component mass includes a resin component filled into the outer cartridge and a hardenable component filled into the inner cartridge. The space within the outer cartridge is divided into two separate regions, preferably one following the other in the elongated direction of the outer cartridge. The resin component is present in each region, however, a thixotropic agent is included in one region but not the other so that the viscosity of the resin component is greatly increased within the one region. Preferably, the increased viscosity is present in the region of the outer cartridge forming the trailing end of the container when it is inserted into a borehole so that flow out of the borehole is, for practical purposes, prevented. Accordingly, a resin component which is highly fluid prior to the mixing operation, such as methylmethacrylate (MMA) can be used.

IPC: H02P8/00
Filed: 1985-05-02
Abstract: PURPOSE:To prevent the stepout phenomenon of a pulse motor by stopping the pulse output for the prescribed time when an input command position is varied. CONSTITUTION:If a new position command input is applied when the rotor of a pulse motor does not arrive at a command position, the output of a comparator 32 becomes H level since the inputs A, B of the comparator 32 are different. At this time, a settling time set value is preset in a frequency dividing counter 22, which down-counts. A pulse from a borrow terminal BO is not produced during this counting. Since the pulse output from the terminal BO of the counter 22 is not output, a CCW or CW command is not output so that the motor becomes a stopped state.
