Title: Floating shape changing toy
Inventor: INANAGA KOICHI
IPC: A63H33/00
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To make a toy rich in variation of playing and capable of keeping persistence by floating a shape memory alloy wire, whose profile can be changed by heating, by floats onto a water surface. SOLUTION: A profile of a bird is formed using a shape memory alloy of a Ti-Ni alloy and the transformation point of the shape memory alloy is made, for instance, 35-45 deg.C. Next, the shape memory alloy is extended in a straight line and inserted through holes, larger than the diameter of the shape memory alloy wire, of ball shaped floats 2. After all floats are inserted by the wire, both ends of the wire are fastened by cone shaped floats 3. When the floating shape changing toy is held in hand and floated on the surface of hot water at 35-45 deg.C in a bath, the profile of the floating shape changing toy is instantly changed to the original bird shape flat on the hot water surface. The toy can be held by a hand to play moving, sinking, etc. Further, when a person wants to enjoy the change again, the toy is taken out from the bath to soften the toy in air or water to shape the toy into an arbitrary shape.

Title: Power unit for cathode-ray tube for liquid crystal display backlighting
Inventor: TAKAHASHI KOJI
IPC: G02F1/133
Filed: 1989-10-02
Abstract: PURPOSE:To enable the cathode-ray tube to put on in low-temperature environment after a power source is turned on without fail in whatever state a brightness adjusting means is by adjusting the brightness of the cathode-ray tube used as the backlighting light source of a liquid crystal display device according to the level of a voltage applied to the tube from the inverter type power unit. CONSTITUTION:In a nonillumination period wherein a tube current flows to neither cathode-ray tube 3 nor 4 after the power source is turned on, positive input voltages to comparators 5 and 6 is 0, so their outputs are in a grounded state. The input voltage to the feedback terminal 17 of a switching regulator 1 is therefore 0 and the output of the switching regulator 1 becomes nearly equal to a maximum voltage, i.e. an input voltage VIN. Therefore, a voltage which exceeds an actuation voltage greatly is applied to the cathode-ray tubes even at low temperature and the illumination states are made secure. When the tube current begins to flow, the positive input voltages to the comparators 6 and 7 rise and when they exceed negative input voltages as reference voltages, the outputs of the comparators enter an open state, so that a voltage corresponding to the set state of a variable resistor 15 is applied to the cathode-ray tubes.
