Title: Method and device for cleaning swimming pool
Inventor: PEETERU ZOMUMERU
IPC: E04H4/16
Filed: 1991-10-30
Abstract: PURPOSE: To carry out optimum cleaning by detecting and avoiding an obstacle or the like in a device for cleaning a swimming pool. CONSTITUTION: When a front-side contact rail 18 is operated, a cleaning device 100 is rotated around the axis of the device in a plane until a rear-side switch rail 20 is operated. A signal being detected at that time is used to change a traveling device to retreat traveling and at the same time to straighten out the cleaning device 100 at a place where an obstacle exists. The signal related to the straightening-out is used for changing the traveling device to advance traveling. During a motion direction due to at least one sensor 25 being provided in a casing 1 of the cleaning device, an instantaneous motion direction regarding a running line or being directed toward a running zone-shaped part is detected.  The amount of deviation being detected at that time is converted to the signal, and is switched to advance and retreat traveling for reciprocating in a swimming pool so that it can be used to correct direction motion.

Title: Shift control device for automatic transmission having manual shift range
Inventor: NISHINO KENJI
IPC: F16H61/18
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To avoid occurrence of skip up-shifting and generation of heat in retrodding an acceleration pedal after release of a foot for up-shifting and changeover of D to M range. SOLUTION: Switching from a D range to an M range is carried out at an instant t2 during shift of shifting time from a first to fourth speed stage, from the instant t1 of a shift command of the first and forth speed stag accompanied with release of a foot. And an acceleration pedal is retrodden at an instant t3. A command gear position GPNEXT is left at the fourth speed stage at changeover instant t2 from the D to M range, since the gear position for the manual shift range is used. At the retrodding instant t3, instead thereof, the command gear position GPNEXT adopts the gear position for automatic shift range obtained from a downshifting line for the D range. The value GPNEXT is varied sequentially from the third to second, second to first speed at every time it crosses over the down-shifting line.  This variation of the command gear position GPNEXT is not reflected on actual shift due to shift response delay. The automatic transmission is kept at the first speed, as indicated by temporal variation of the present selected gear position GPOWT. Skip shifting is not generated.

IPC: H04N5/10
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To discriminate a field without need for eliminating an equivalent pulse even when a phase of a vertical synchronizing signal is not coincident with a phase of a horizontal synchronizing signal. SOLUTION: A V-sync (2) from a terminal 2 is differentiated by a differentiation circuit 3, the differentiated signal is delayed (4) up to a position at which an equivalent pulse period is finished by a delay circuit 4 and the delayed signal is fed to a 1/2 H pulse generating section 5, which generates a pulse of 1/2H width descended by the signal (4). The 1/2H pulse (5) and the negative H-sync (1) from the terminal 1 are inversely given to an OR gate 6 respectively, from which the calculated signal (6) is fed to an F.F circuit 7. The F.F circuit 7 is reset by the signal (4) from the delay circuit 4 and provides an output of an inverted output signal while receiving the signal (6) from the OR gate 6. Thus, the field is discriminated by the polarity of the output of the F.F circuit 7.
