Title: Electronic device and controlling method thereof
Inventor: NAKAMIYA SHINJI
IPC: H02P8/12
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce wasteful power consumption, detecting power generation state without causing charging efficiency to be deteriorated and without being affected by the change of constituting devices including a generator and a motor. SOLUTION: The output of normal motor driving pulses or high-frequency magnetic field detecting pulses or the like is stopped when correcting driving pulses are outputted so that wasteful consumption of electric power decreases. Also, a power generation detecting circuit performs the detection of the power generation through a route different from an actual charging route so that the decrease of the charging efficiency is not brought about. In addition, it is unnecessary not only to determine from an actual measurement the power generation that causes abnormal motor driving but also to set from the actual measurement the power generation which becomes a reference every time the generator, the motor and the structure of the mechanism are changed.

Title: Treatment process of liquid waste of developer/fixer for developing photograph such as x-ray photograph and liquid waste of antifreezing fluid or the like
Inventor: FUJIMASU JIRO
IPC: C04B18/04
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To reutilize liquid waste of a developer and a fixer, each used for developing a photograph such as X-ray photograph, and liquid waste of an antifreezing fluid or the like, without discharging such liquid waste as effluent by detoxifying the liquid waste and solidifying the detoxified liquid waste. SOLUTION: In this treatment process for detoxifying such liquid waste and solidifying the detoxified liquid waste, there is such a problem that since the pH value of the liquid waste of a developer or antifreezing fluid is greatly different from that of a fixer, the liquid waste of the developer or antifreezing fluid must separately be treated from the liquid waste of the fixer. Also, while a portland cement-based solidifying agent is capable of easily solidifying such liquid waste even at a high pH value, an alumina cement-based solidifying agent can appropriately be used for solidification of such liquid waste at a pH value of <=7.  Thus, the treatment process involves treating the liquid waste of the developer or antifreezing fluid with a normal portland cement-based solidifying agent and treating the liquid waste of the fixer with an alumina cement-based solidifying agent, to solve the above problem.
