Title: Detecting device for sheet break on roof of building
Inventor: YOSHIMATSU KENJI
IPC: G01N27/20
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To nondestructively and accurately detect a broken part of a waterproof sheet by carrying a current between a moving electrode moving above the sheet and a plane electrode under the sheet, and by measuring a current carrying change. SOLUTION: As a moving electrode 30 is moved on a protection material 19 on a building roof, a natural electric potential of a plane electrode 25 under the waterproof sheet 12, i.e., a potential difference between the moving electrode 30 and the plane electrode 25, is measured by a measuring part 28 at mesh-like measurement points. When the waterproof sheet 12 has a broken part, a conductive liquid D of the moving electrode 30 oozes to the plate electrode 25 through the broken part so that both the electrodes 25, 30 are electrically connected. The measuring part 28 measures a value close to the natural potential of the plane electrode 25, while measuring the natural potential value when the moving electrode 30 approaches on a position of the broken part.  When the waterproof sheet 12 has no broken part, the conductive liquid D does not ooze to the plate electrode 25 so that both the electrodes 25, 30 are insulated from each other. Accordingly, the natural potential is not measured. Thus, the presence of the broken part is decided according to a recorder of the measuring part 28. By finely measuring near a measurement point of a value close to the natural potential, the broken part is detected and specified.

Title: Regeneration controlling unit for hybrid vehicle
Inventor: WAKASHIRO TERUO
IPC: B60K6/20
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To determine the optimum regeneration capacity that matches the deceleration state of a vehicle and the charging state of an accumulating device while bringing out the power generating efficiency of a motor sufficiently, by correcting the regeneration power at a rate in accordance with the difference between the regeneration capacity and the overcharged capacity. SOLUTION: In a regeneration controlling unit ECU 7, the sum is obtained of the actually detected capacity of a capacitor of an accumulating device 5 and decelerating regeneration capacity. Then, preset maximum permissible charging capacity is deducted from the sum to calculate the overcharged capacity. A correcting coefficient is obtained from the rate calculated by dividing the difference between the decelerating regeneration capacity and overcharged capacity by the decelerating regeneration capacity. The regeneration capacity is corrected by multiplying it by the correcting coefficient. This constitution enables the regeneration to be controlled in such a way that the accumulating device 5 does not exceed the maximum permissible charging capacity via a power drive unit 4 under the control of a motor controlling unit ECU 6.

Filed: 1990-11-08
Abstract: PURPOSE:To improve both ozone concentration and production efficiency of ozone by connecting an auxiliary pipe equipped with an auxiliary pump in parallel to a pump for circulating cooling water to a water chamber formed from tube sheets. CONSTITUTION:The aforementioned water-cooled ozonizer is obtained by airtightly passing both ends of ozonizing tubes 1 having an outlet and inlet of a gas to be handled at the ends (1a) and electrode terminals through a pair of parallel tube sheets 2 and connecting an auxiliary pipe 14 equipped with an auxiliary pump 13 in parallel to a pump 5 to a water chamber 3 in circulating cooling water flowing through a heat exchanger 4 to the water chamber 3 formed from the tube sheets with the pump 5. In the above-mentioned apparatus, since the flow in the water chamber 3 will not pass through the pump 5 having the heat exchanger 4, the fluid pressure loss in the pipe of the heat exchanger 4 is not increased. Nevertheless, the cooling water passes through the water chamber 3 at the sum total of the flow rates in the pump 5 and the auxiliary pump 13 and the flow is mixed or stirred to increase the flow velocity. Thereby, heat exchange ratio with the ozonizing tubes 1 is improved and the ozonizing tubes are sufficiently cooled. The ozonizing tubes perform ozonizing action at a low temperature.
