Title: Switching power supply
Inventor: KITANO SABURO
IPC: H02M3/338
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To lower the switching frequency during waiting condition with a low load in order to improve power conversion efficiency with a simplified structure. SOLUTION: A switching power supply 11 of the RCC(ringing choke converter) system outputs an exciting energy accumulated within a transformer N during the ON period of a main switching element Q to the secondary side during the OFF period, and thereafter feeds back a ringing pulse generated in a control winding N3 of the transformer N to the gate of the main switching element Q via a DC-cut capacitor C4 and then drives the main switching element to the ON state. In this case, a transistor TR3 is provided to the gate of main switching element Q. During a light loading condition, charges are accumulated in the base from a sub-control winding N4 in the OFF timing of the main switching element Q.  Even if the main switching element Q becomes ON timing due to such charges, the transistor TR3 turns ON for the predetermined period continuously from the OFF period, thereby by-passing the ringing pulse and stopping re-starting by this pulse.

Title: Autonomous traveling vehicle
Inventor: KAWAGOE NOBUKAZU
IPC: G05D1/02
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To improve user's operability by selecting a straightforward direction of zigzag traveling in a different area based on its shape when a vehicle detects an area that is different from a set area during traveling in the set area. SOLUTION: A cleaning robot measures the scale of a rectangular area by using front and side range sensors and selects the direction that corresponds to the longer side between the two sides as a straightforward direction. Thereby, it can reduce the number of its turns and shorten its traveling time. When it detects a recess of a wall by the rapid rise of a measurement value of a left range sensor during its straightforward advance along the wall in a rectangular area S9, it stores the depth of the recess of the wall, turns to the recess of the wall and advances straight, measuring distances to left and right walls of a rectangular area S10.  It compares one distance that decides the scale of the rectangular area with the stored distance, selects the direction that corresponds to the distance that shows the larger value between them as a straightforward direction of the cleaning robot and performs zigzag traveling in the area S10.

Inventor: WADA CHUZO
IPC: F23D3/18
Filed: 1984-11-30
Abstract: PURPOSE:To improve electric source life by a method wherein a closing circuit is formed by electric source, a capacitor and a change-over switch, and a resistance is connected in parallel to the capacitor of this closing circuit through the change-over switch while the rotating time of a motor is controlled by a charging time at the capacitor. CONSTITUTION:When combustion is started due to ascending of a wick 1 by a knob 7, the common terminal 24a of the change-over switch 24 interlocked by the knob 7 changes to the fixed opening terminal 24 ide and the electric charge charged to the capacitor 23 during stopping of the combustion is discharged while the circuit of the electric source 21 is opened, the motor 22 for the smell absorption fan stops and ther current also is not flow in this circuit. When the fire is extinguished by descending of the wick 1 under these condition, the common terminal 24a returns to the fixed closing terminal 24c side, the charging for the capacitor 23 is started and the rotation of the motor 22 also starts. When the charging for the capacitor 23 is completed, the rotation of the motor stops, however, kerosine vapor evaporated continuously from the upper portion of the wick 1 is sucked into a tank 4, thereafter, it may be discharged to the outside.
