Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method, for voltammetry, in which a measurement is continued automatically until a precise measured value is obtained when a container is set so as to start the measurement and in which the measurement can be performed in a short time and with high accuracy. SOLUTION: This voltammetric apparatus is provided with a control part which applies a voltage across a working electrode 2 and a counter electrode 1 in order to sweep the potential of the working electrode 2 within a range of a prescribed potential from the electrode potential of a comparison electrode part 3 and which detects the prepeak value of a current flowing across the working electrode 2 and the counter electrode 1. In addition, it is provided with a monitoring means which monitors a potential across the working electrode 2 and the comparison electrode part 3. The control part performs a first voltage sweep.  When the monitoring means detects that a spontaneous potential across the working electrode 2 and the comparison electrode 3 is stabilized in a prescribed range value, the control part performs a second voltage sweep, and it detects a prepeak value in the second voltage sweep so as to be used as measured data.

IPC: A01G27/00
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To adequately carry out watering of seedlings and the other control so as to save labor in production and sale aspect of plants. SOLUTION: 1. The under pool tray is a water-pooling container having a structure in which a base with a groove is integrated in order to supply water from the bottom while placing a tray in or on which seedling pots are put or various kinds of pots and is combined with a water supplying and draining device in which a vertical lines- bundled hollow filter 1 is built as a part of the groove. 2. A water-sucking part of the water-supplying and draining device is slightly wide and has L shape as a whole. As a result, the water-sucking part facilitates water suction by a hose. The inlet of the water-sucking part is housed in dark place of the bottom in a cylinder. The vertical lines-bundles hollow fiber 1 has a structure capable of extruding out waste by water current when water is sucked and preventing waste when water is drained.  A water draining pipe with the vertical lines-bundled hollow filter 1 extends through the under pool tray and the water sucking pipe to the outside. The water draining pipe is composed of a material having light-blocking property so that a part which became slightly slender and located at the tip of the water draining part 3 is not exposed to light.

Title: Electric car
Inventor: KOSHIZAWA TOSHIBUMI
IPC: H02H7/00
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent the contact of a switch means for supplying power from being damaged even if a key switch is pressed by a mistake when a large current as in starting acceleration flows. SOLUTION: When a key switch 6 is turned off, an acceleration pedal signal cancellation circuit 10 is switched to the position of a solid line, thus supplying an acceleration signal corresponding to acceleration idling to a motor control device 3 for drive regardless of the position of the acceleration pedal. On the other hand, when the key switch 6 is off, an off delay circuit 9 is actiuated and a main relay 2 is kept to be on for a specific amount of time without being immediately furned off. During that specific time, the motor control device 3 for drive controls a motor 5 for driving vehicle in idling operation and hence current flowing to the main relay 2 is reduced when the main relay 2 is turned off, thus preventing a contact from being damaged regardless of breaking.
