Title: Charger
Inventor: NAKANO OSAMI
IPC: H02J7/02
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent an accident caused by an incorrect connection between a charger and a power supply by checking an AC power supply input system by means of a voltage doubler control circuit and charging the charger with charging voltage of a charging voltage converting circuit or cutting out the input of power based on the output of an abnormal voltage detecting circuit. SOLUTION: A power supply 3 for a charger is provided with a means for converting the input power to DC 12V even if the input power is either AC100V or AC200V. A voltage doubler control circuit 6 judges whether the input voltage is 100V or 200V. An abnormal voltage detecting circuit 15 allows the charger to operate when the voltage of a capacitor 14 is within a predetermined range and cuts out the input of the charger by opening a switching section when the voltage of the capacitor 14 is out of the predetermined range. A charging voltage converting circuit 17 converts the DC200V power to DC48V power. A memory and a control circuit 20 control the entire operation of the charger including the voltage doubler control circuit 16 and the abnormal voltage detecting circuit 15.  Owing to this structure, the charger never operate when the connection is incorrect, and so the damage of the charger and other components can be prevented.

Title: Denitrification catalyst and manufacture thereof
Inventor: URUGA KUNIJI
IPC: B01J23/30
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent a catalytic component from being deactivated by high temperatures at the time of flame spraying by spraying by flame a porous denutrufication catalyst component layer to one or both of the surfaces of an antioxidative metal thin film. SOLUTION: When forming a denitrification catalyst layer on a heat-resistant metal thin sheet, a method for flame spraying at low temperatures is adopted. For example, if a method for flame spraying with a high calorific value of plasma is adopted, the activity of a catalyst is extremely deteriorated. Therefore, the method for flame spraying at low temperatures using an inflammable gas, oxygen, at 3000 deg.C or less should be adopted. Thus it is possible to enhance the cohesive strength of the catalytic component and a metal carrier while suppressing the denitrification performance.  Consequently, the catalytic function is prevented from being lost by the separation of the catalytic component from the surface of the metal carrier, in case this heat-resistant metal thin sheet with the denitrification catalyst layer is applied to a finished product such as rolling stock suffering from vibration. In addition, the manufacturing step can be simplified and thereby the cost reducing effect is enhanced.

IPC: H04J3/22
Filed: 1986-12-26
Abstract: PURPOSE:To avoid mis-detection of a channel or a signal error by providing a switching control bit in a frame on a multiplex line, sending a switching control bit through inversion together with the switching of a time slot assign table of a transmission frame, allowing a reception side to detect the inversion to switch the time slot assign table. CONSTITUTION:A sender side sends a TS table (time slot assign table) provided in a frame, that is, a switching discrimination bit (SW bit) from which frame the switching takes place during the frame assignment. Thus, when frames #1, #2 including the SW bit '1' are sent by the TS table A, the reception side detects the SW bit '1' to receive the frames #1, #2 by a TS table A. When frames #3, #4, #5 are sent by a TS table B together with the SW bit '0', the reception side detects the SW bit '0' and the frames #3, #4, #5 of the TS table B are received.
