Title: Electrode for projection welding machine
Inventor: AOYAMA YOSHITAKA
IPC: B23K11/30
Filed: 1993-08-04
Abstract: PURPOSE:To perform sure projection welding by holding a part by a magnet and checking the existence of the part by a sensor. CONSTITUTION:When an axis part 10 of a bolt 9 held by a part supply means 14 starts to advance into a receiving hole 20, it is brought in positively by the magnet attraction force generated on the tip of a heat insulating piece 27 and the part is inserted smoothly thereinto. At this time, the sensor 23 detects the existence of the axis part 10 to produce an operation permission signal of a movable electrode 5. If the both 9 does not fall in and is caught in the abnormal position, since the sensor 23 cannot detect the axis part 10, an operating signal is sent to a solenoid valve 47 from a timer 48 after the lapse of specified time, the air is injected toward the receiving hole 20 from an air injection hole 40 and the bolt 9 being caught is blown off and removed.

Title: Thermal transfer dye donating material
Inventor: USUI HIDEO
IPC: B41M5/30
Filed: 1990-08-31
Abstract: PURPOSE:To improve the fusion at the time of thermal transfer by constituting a dye layer of a dye, a binder and a silicone type compound and controlling the coating amount per a unit area of the silicone type compound so as to increase the same toward a color part becoming later in a transfer order. CONSTITUTION:A thermal transfer dye donating material is formed by providing a plurality of dye donating layers to one surface of a support and the dye donating layer contains a dye, a binder and a silicone type compound and the coating amount per a unit area of the silicone type compound is increased toward a color part becoming later in a transfer order. For example, in such a case that transfer is carried out in the order of yellow   magenta   cyan, the addition amount of the silicone type compound is set to the relation of cyan dye donating layer > magenta dye donating layer > yellow dye donating layer. When the addition amount of the silicone type compound is increased so as to become 1.1-3 times (wt. basis) that of the silicone type compound of the dye donating layer transferred immediately before, a good results can be obtained. As the silicone type compound to be used, unmodified or modified silicone oil or a solid silicone polymer soluble in an org. solvent such as toluene is used.

IPC: H03K17/10
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To obtain a static power converter of a gate drive circuit power supply type, which has a power source on a main circuit side and moreover enables power supply structure employing a circuit device with a low withstand voltage. SOLUTION: A semiconductor switching device SW1 of a main circuit is driven by a gate drive circuit GATE, and a necessary DC power is supplied to the gate drive circuit from a power supply PS.

Title: Fluid flow dividing device
Inventor: HIRAYAMA YOSHIO
IPC: F16K31/70
Filed: 1984-10-30
Abstract: PURPOSE:To divide the fluid flow in response to a change in the temperature of the fluid by disposing a valve device in each branch pipe that actuates the valve by shape memory alloys having different temperature characteristics and a resilient member. CONSTITUTION:When the temperature of fluid in a main pipe 1 rises and the temperature of fluid around a shape memory alloy 5 exceeds a predetermined value, said shape memory alloy 5 extends to cause the valve body 3 which was in a position shown in a broken line to contact the valve seat 2a to prevent the fluid from flowing from the main pipe 1 to a branch pipe 2. When the temperature in the main pipe 1 becomes low, and the temperature of the fluid around the shape memory alloy 5 becomes lower than said predetermined value, a resilient member 6 displaces the valve body 3 to the position as shown by the broken line to open the valve as it compresses and deforms the shape memory alloy 5.

Title: Nonwoven fabric for printing
Inventor: UMETSU NORIO
IPC: B32B27/12
Filed: 1990-08-31
Abstract: PURPOSE:To enable offset printing having a high grade to a nonwoven fabric having high tear resistance, to obtain a printing finishing effect equal to art paper in a short time even when the nonwoven fabric is thinned and lightened and to facilitate solid printing by forming a resin layer, to which a specific cloth filler is added, as an ink fixing layer. CONSTITUTION:An ink fixing layer containing a resin layer formed of a resin composition containing 10-40wt.% non-baked clay, 1-15wt.% titanium dioxide and 1-10wt.% calcium carbonate and/or baked clay as fillers is formed onto at least one surface of a nonwoven fabric. A compounding ratio is kept within the range, thus improving the ink absorptivity of the resin layer, drying characteristics and grab, then shortening a printing time and enhancing the grade of printing. When the quantity of calcium carbonate compounded exceeds 10wt.%, the solvent absorptivity of printing ink of the resin layer is exceeded, and a gloss is insufficient and the value of printing is decreased on printing. When baked clay exceeds 10wt.%, the resin composition is difficult to be mixed uniformly.
