Title: Gripping tool for small object
Inventor: ICHIKI KATSUNORI
IPC: B81B3/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To conduct work with a small object gripped easily and steadily by deforming two thin sheet-shaped elastic spring parts which extend from a base part, and griping a small object between the springs. SOLUTION: Two thin sheet-shaped elastic spring parts 2A, 2B are extended from the base part 6A of a main body 6 at a gripping tool 1. The tops of the elastic spring parts 2A, 2B are provided with small object retaining parts 3A, 3B for gripping a small object 5. When the small object 5 is gripped between the retaining parts 3A, 3B, the elastic spring parts 2A, 2B deflect and retain the small object 5 with elastic reaction. Its force is constant, therefore, the small object does not falls on the way nor be broken. The gripping tool 1 is fitted at the top end of a pallet, and when a working place moves, it moves with the pallet with a robot arm for movement. It is thus possible to grip the small object with high closeness without causing any danger such as falling and breakage.  It is also possible to conduct operation by collecting a large number of small objects at one point, thus improving workability.

Title: Production of dark iridescent pigment
Inventor: KOBAYASHI SHINICHIROU
IPC: C08K9/00
Filed: 1982-03-26
Abstract: PURPOSE:To obtain a dark iridescent pigment which has good compatibility with resin and pigment and is safe and whose tint can be easily controlled, by heat-treating in an NH3 stream flaky mica covered with titanium dioxide or a composite material thereof with a metal oxide. CONSTITUTION:Flaky mica covered with titanium dioxide (including hydrate) or its composite material (including hydrate) and a metal oxide is heat-treated in an ammonia stream at 600-950 deg.C to reduce titanium  dioxide to titanium monoxide. When the reducing temp. is lower than 600 deg.C, the reduction of titanium dioxide to titanium monoxide hardly proceeds, while when the temp. is higher than 950 deg.C, sintering or the growth of particles is remarkable and mica itself begins to decompose in the reduction. Thus, such a temp. is not preferred. By controlling reduction conditions, the amount of the produced titanium monoxide can be controlled and the desired color such as blue, bluish black, black or brownish black can be obtd.

Filed: 1988-03-02
Abstract: PURPOSE:To obtain a normalizing circuit at high speed by providing a circuit for normalizing a focus and/or tracking error signal, using a sum signal for normalizing said signal, and switching the sum signal to a peak holding or through signal. CONSTITUTION:A focus error signal 1 and a tracking error signal 3 are inputted to an AGC circuit 2 for normalizing the respective error signals. A sum signal (the sum total of an output of a photodetector) 4 controls the circuit 2 through a switch 5. At the time of reproducing, the switch 5 is switched to a peak holding sum signal side (b side) by an AGC control signal 8 and 9 and a switch 7 is closed. At the time of erasing and at the time of recording, the switch 5 is switched to a through sum signal side (a side) by the signals 8, 9 and the switch 7 is opened. By inserting this delay time, the possibility that the sum signal is held before laser power drops completely is eliminated. In such a way, instability given to both focus and tracking servos can be eliminated.
