A safety belt includes a length adjuster for securement of one end of a belt webbing, with the length adjuster being constantly biased in a direction of retraction of the belt webbing. A locking mechanism, when rendered effective, inhibits the length adjuster from turning in a direction of protraction of the belt webbing and is operatively connected to a control unit which, when activated, applies a locking function to inhibit the belt member from being pulled out of the retractor and being retracted, thereby preventing a lengthening and shortening of the belt webbing. Operatively connected to the control unit is an actuator which is constructed to allow an occupant, upon actuation, to override the locking function and thereby render the locking mechanism ineffective to enable the occupant to adjust a length of the belt webbing.

Implantable drug delivery devices are provided lo have a deployment shape for implantation in the body and a retention shape for retention in the body. The device may have one or more elongated drug reservoirs containing a drug, mid the drug reservoir may be formed from a deformable material. In one case, a first filament is attached to the first end of the drug reservoir and second filament is attached to the second end of the drug reservoir, wherein a fastener is positioned about the first and second filaments to permit shortening and prevent lengthening of the filaments with reference to the ends of the daig reservoir, as a means for transforming the device from the implantation shape to the retention shape.

A separator includes a non-woven fabric substrate having pores, fine thermoplastic powder located inside the pores of the non-woven fabric substrate, and a porous coating layer disposed on at least one surface of the non-woven fabric substrate. The fine thermoplastic powder has an average diameter smaller than that of the pores and a melting point lower than the melting or decomposition point of the non-woven fabric substrate. The porous coating layer includes a mixture of inorganic particles and a binder polymer whose melting point is higher than the melting or decomposition point of the fine thermoplastic powder. In the porous coating layer, the inorganic particles are fixedly connected to each other by the binder polymer and the pores are formed by interstitial volumes between the inorganic particles. Previous filling of the large pores of the non-woven fabric substrate with the fine thermoplastic powder makes the porous coating layer uniform.

A shift register for reducing size of a display apparatus through a reduction in falling edge time of a scan pulse. The shift register includes stages for sequentially outputting carry pulses and scan pulses. Each stage includes a carry output unit for generating a carry pulse, based on a first discharge voltage and a clock pulse having a low-level voltage with a level substantially equal to the first discharge voltage, and supplying the carry pulse to at least one of an upstream stage and a downstream stage, a scan output unit for generating a scan pulse, based on a second discharge voltage having a higher voltage value than the first discharge voltage and the clock pulse, and supplying the scan pulse to a corresponding gate line, and a node controller for controlling voltages at nodes connected to the carry output unit and the scan output unit.

An ink jet recording head includes ejection energy generating elements for ejecting ink, flow passages for supplying the ink from an ink supply port to the ejection energy generating elements through a common liquid chamber, a partition wall formed between adjacent two flow passages, a member disposed between the partition wall and the ink supply port, and an opening formed between the partition wall and the member. A flow resistance in the opening from one of the adjacent two flow passages to the other flow passage is different from that in the opening from the other flow passage to the one of the adjacent two flow passages.

Induction of telomere shortening, G2 arrest and apoptosis in telomerase positive cancer cells using acyclic nucleoside analogs has been disclosed. In addition, methods for impairment or prevention of tumorigenic telomerase positive cells from having a chance to grow into a tumor and methods for promoting tumor regression (decrease in size of an established tumor) using acyclic nucleoside analogs has been disclosed.

Acyclic nucleoside analogs such as acyclovir, ganciclovir, penciclovir and the corresponding pro-drugs, i.e., valacyclovir, valganciclovir and famciclovir, respectively have been identified as inhibitors or antagonists of both telomerase (encoded by TERT) and reverse transcriptase encoded by L-1 (LINE-1) RT, and as useful for treating or preventing cancers induced or mediated by the two enzymes. Method of treating or preventing such cancers in patients involves administration of a therapeutically effective amount of a composition having an inhibitor or antagonist of the reverse transcriptases in cells of the patients. The inhibitor or antagonist blocks lengthening of telomeres in telomerase positive and telomerase negative cells. Methods and kits for detecting pathologically proliferating cells expressing TERT and L1RT are also disclosed.
