IPC: A47K3/062
Filed: 2001-09-20
Abstract: PROBLEM TO BE SOLVED: To provide an assembly type portable simplified bathtub with light weight, superior water imperviousness and stability so that even a single caregiver can easily bath a severely handicapped person or a person needing care on a bed. SOLUTION: The bathtub with light weight, water imperviousness and stability is provided by combining the morphologically stable portable bathtub and the foldable waterproof sheet bathtub where complete water imperviousness and light weight can be expected but which is morphologically unstable.

Title: Light-emitting diode drive circuit, method of control thereof, and electronic equipment therewith
Inventor: TAKAHATA HIROKATSU
IPC: H05B37/02
Filed: 2001-11-09
Abstract: PROBLEM TO BE SOLVED: To provide an LED drive circuit stably supplying an optimal current to LEDs. SOLUTION: Output voltage Vg is produced based on the electromotive force Vf of a chemical battery 31. A current I corresponding to the output voltage Vg flows in a load circuit 20. The current I is converted to a voltage Vm by a current-limiting resistance 22. A comparator 45 compares the voltage Vm to a reference voltage Vr; if the voltage Vm is less than the reference voltage Vr, an output signal Vh becomes 'L'. Then the output signal Vk of a comparator 42 depends on an output signal Vj of an oscillator 43. Thus, a transistor 41 is turned on/off, approximately in synchronism with the output signal Vj. When the transistor 41 is on, the energy of the chemical battery 31 is stored in an inductor 49. When the transistor 41 is off, currents flow into the inductor 49 via a diode 48 to maintain a certain output voltage Vg.

Title: Digital camera device and its electronic zoom processing method
Inventor: KANDA SHINJI
IPC: H04N5/262
Filed: 2001-11-14
Abstract: PROBLEM TO BE SOLVED: To restrain vertical noise without increasing a circuit size, when an image picked up by using an interlace scanning method is enlarged by an electronic zoom processing. SOLUTION: When illuminance difference between two adjacent lines data (control lines) which are used for forming interpolation line data is larger than a previously set reference value, corrected line data in which the illuminance difference is reduced are formed about one line data, and the corrected line data (pseudo-control line) and the other line data (true control line) are used, thereby forming interpolation line data. By using the interpolation line data and the original line data, electronic zoom processing is performed and frame image data are outputted. As a result, the vertical noise can be reduced to a degree that visual deterioration is not noticed, without using a frame memory.

Filed: 2001-11-28
Abstract: <P>PROBLEM TO BE SOLVED: To prevent malfunction in an internal circuit at change over of operation modes in a semiconductor integrated circuit having a plurality of operation modes.  <P>SOLUTION: A first and a second voltage generation circuits generate a first internal power source voltage to be supplied to a first internal power source line and a second internal power source voltage to be supplied to a second internal power source line, respectively. A short circuit short-circuits the first internal power source line and the second internal power source line when both the first and the second voltage generation circuits stop operation. The first and the second internal power source lines become floating and the electric charge stored in each internal power source line is gradually released. On this occasion, the charge is re-distributed and the first internal power source voltage and the second internal power source voltage become the same values and continue to descend. Therefore, the reversal of the first and the second internal power source voltages can be prevented, and the malfunction in the internal circuit connected to each of the first and the second internal power source lines can be prevented.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a part mounting method in which a part is surely mounted in a normal direction.  <P>SOLUTION: An image 20' of an absorbed part is recognized with a recognition device comprising a specified recognition region 7b. Based on a result of recognition, the part is mounted on a prescribed position of a board. When the part is recognized, a window 30 of a specified size is set at an image position of a previously found characterizing portion, and it is decided whether or not the image 20b' of the characterizing portion of the part 20 is positioned in the window. If not, the window is rotated by 90° around a center C of the part image as an axis, to position the image in the window. Since the amount of rotation shows the slippage of the part from the normal direction, the slippage is corrected to mount the part. As a result, the part is surely mounted in the normal direction.  <P>COPYRIGHT: (C)2003,JPO
