Title: Slip preventing device for vehicle
Inventor: WAKATA HIDEO
IPC: B60T8/175
Filed: 1983-11-04
Abstract: PURPOSE:To aim at enhancing the running stability and accelerating capability of a vehicle, by controlling engine torque in accordance with a road-surface frictional coefficient which is estimated based upon the condition of trailing wheels, a tracting wheel speed and a trailing wheel speed. CONSTITUTION:A compare circuit 9 receives a tracting wheel speed signal from a tracting wheel speed sensor 1 and a trailing wheel speed signal from a trailing wheel speed sensor 2. Further, the trailing wheel speed signal is differentiated to compute the trailing wheel acceleration from which a road-surface discriminating circuit 8 estimates the road-surface frictional coefficient mu that is delivered to the comparator circuit 9. The comparator circuit 9 compares the tracting wheel speed with the trailing wheel speed to judge occurrence of a slip when the tracting wheel speed is predetermined number (k) times higher than the trailing wheel speed, and therefore torque control device 11 controls engine torque through a control signal generating circuit 10. Further, the value of K is set to be small as the estimated frictional coefficient mu is small, but is set to be large as the mu is large.

Title: Cleaning method for semiconductor wafer
Inventor: TOSHIRO YUUJI
IPC: H01L21/316
Filed: 1987-08-22
Abstract: PURPOSE:To remove particles, organic matters and heavy metals on a semiconductor wafer completely by combining washing by water, pickling and ultrasonic cleaning. CONSTITUTION:A semiconductor wafer before thermal oxidation is washed for sixty min by ultrasonic waves, to which high frequency of 800kHz is applied, by ultra-pure water. Particles on the wafer are removed completely by the process. Cleaning is conducted for twenty min in comparatively low frequency of 30kHz by the mixed liquid of NH3OH/H2O2/H2O at 70 deg.C, thus getting rid of organic matters, heavy metals, etc., on the surface of the wafer. A natural oxide film by the solution is shaped on the surface of the wafer at that time, and a damaged layer on the surface of the wafer generated through high-frequency ultrasonic cleaning is oxidized. The oxide film is taken off by diluted HF, and a layer, which is hardly damaged, is exposed onto the surface of the wafer.

Title: Support film for pressure-sensitive adhesive tape and pressure-sensitive adhesive tape or sheet
Inventor: SAKASHITA SADAJI
IPC: C09J7/02
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To obtain a pressure-sensitive adhesive tape or sheet undergoing a small dimensional change even when heat is applied or even after a long term, freed from deformations such as winding voids even when it is a rolled one, and undergoing little change in pressure-sensitive adhesiveness by containing a tackifying resin in the support film. SOLUTION: The support film used may be anything that can contain a tackifying agent and is exemplified by a single- or multi-layer one made of paper, a plastic film, a foam, a nonwoven fabric, or the like. Especially when the support film used is a polyolefin resin, the incorporation of a tackifying agent thereinto is effective against the liability of the pressure-sensitive adhesive to deformations such as winding voids due to heat or a lapse of time. The polyolefin resin used is desirably one based on a polyethylene, a polypropylene, an ethylene/propylene copolymer, or a mixture of a polyethylene with a polypropylene. The amount of the tackifier added is desirably 1-50 wt.%. The effect is marked especially when the pressure-sensitive adhesive used to form the pressure-sensitive adhesive layer of a pressure-sensitive tape is a rubber- based one containing a tackifier.

SOLUTION: This net-like cylindrical body 11 is secured on the external periphery of the hose 10 in at least a middle section of a hose 10. When the section, where the network cylindrical body is secured, is made to abut on the guide section 24 of a clip 20 and is pressed further, a securing section 22 is widen, widening the space width of an insertion opening section 23. In addition, the insertion opening section 23 is brought into contact with the net-like cylindrical body 11 secured to the hose 10, but since the friction resistance of the polyamide 12 of the net-like cylindrical body 11 is small, smoothing sliding, the hose 10 is smoothly inserted into the cylindrical section of the securing section 22 from then insertion opening section.  After the insertion of the hose 20 into the securing section 22, the securing section 22 returns to the original position due to its elastic reaction force, holding the hose 10.
