Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To improve a drain function of a condensed water film formed on a corrugated fin wall. SOLUTION: A corrugated heat conduction fin 20 for an evaporator has a feature for reducing a critical width of a condensed water film held in an internal channel formed between a pair of branched fin walls 22. Cutout portions 26 of an aligned set penetrates the branched fin wall 22 and is cut out and is further localized in a channel located between an adjacent pair of louver banks 24. In another method, an elongated water film formed continuously on the channel of the fin is separated into a series of discontinuous individual films F1, F2, F3, and each film is formed over the louver bank 24. The individual shorter film drains effectually through the louver bank 24, whereby each film is grown to a critical width more reduced usefully in the channel, and hence there is more reduced interruption of the air flow passing through between the fin walls 22.

Title: Elevator door control device
Inventor: TAWADA MASANORI
IPC: B66B13/14
Filed: 1994-07-06
Abstract: PURPOSE:To increase energy to dust or wind pressure when a door is opened or closed to secure door reopening/reclosing action by executing change of a speed command value and a torque limit value at the time of door reopening/ reclosing at a position before a door stop position. CONSTITUTION:When a threshold of a door is choked with dust in door closing action, a real motor speed 1b of the door is reduced, and a torque command value 1d is increased. When load by the dust is large to let the door closing action impossible at a point La, the point La as a door position at this time is memorized. After this, the door closing action being incomplete is determined by time lapse of more than a normal door closing time, and the door is reopened totally by door inverting action to perform the door closing action. At this time. a speed command value and a torque limit value are changed at a point Lb at Lx before the point La into a speed command value 2a and a torque limit value 2d. The speed and the torque can thus be increased, thereby the real motor speed can be set to let the door easily pass the point La where it stopped at the previous door closing action.

Title: Recorder
Inventor: SAIKAWA SATOSHI
IPC: B41J2/05
Filed: 1993-06-25
Abstract: PURPOSE:To measure environmental temperature more correctly and to stabilize head drive control by detecting temperature at a range away from parts such as a CR motor which undergo a temperature rise, that is, a position less susceptible to the influence of temperature change. CONSTITUTION:Temperature detection is made in a range of a recorder where temperature change is stable rather than in the neighborhood of parts such as a CR motor 203 which undergo temperature rise. Since a temperature sensor 202 is fitted to a carriage base 201, if the CR motor and an LF motor 204 exist near the carriage base 201, environmental temperature near the temperature sensor 202 to detect temperature changes due to the influence thereof. Therefore temperature detection is made in a range in the center of the recorder less susceptible to the influence of parts whose temperature rises. The most ideal range for temperature detection is where external temperature fluctuates least.
