Title: Goggles
Inventor: KATAOKA TOSHIYUKI
IPC: C08L67/04
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To lessen an adverse effect on environment due to disposal by applying a constitution that at least a part of goggles is made of a biodegradable resin composition. SOLUTION: For example, approximately 0.3 g tin oxide power is added to approximately 100 g of approximately 90% L-lactic acid and treated approximately at 150 deg.C under atmospheric pressure, and treated approximately at 150 deg.C under the pressure of approximately 100 mmHg, thereby distilling water. Then, approximately 200 g of orthodichlorobenzene is added thereto and the mixture is treated at approximately 150 deg.C under the pressure of approximately 340 mmHg. At this process, solvents are separated from distillate, and a treatment process is continued until no water is distilled, while the solvents are circulated to the reaction system. ODCB is added to a polymer solution so obtained and cooled to precipitate and filtrate powder. This powder is then added to a mixed solution of conc, hydrochloric acid and isopropyl alcohol.  The resulting product is filtrated, the isopropyl alcohol is washed away and the product is dried, thereby obtaining a polylactic acid powder having logarithmic viscosity of approximately 1.0 d/g. The polymer so obtained is pelletized and injection molded, thereby providing goggles. The goggles so formed ensures strength and a feeling of use equivalent to the conventional synthetic resin goggles, and can restrain an adverse effect on environment due to disposal.

Title: Logic circuit
Inventor: MAEDA KAZUNORI
IPC: H03K19/20
Filed: 1999-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a logic circuit capable of securing a wide timing margin in control signals even under a high-speed operation and improving operation accuracy. SOLUTION: The control signals tA, tB, tC and tD successively rise at each half clock of an external clock CLK. Also, the control signal tx rises at the same timing as the control signals tA and tC and the control signal ty rises at the same timing as the control signals tB and tD. Thus, even when the length of one cycle of the control signals tx and ty in an output circuit is turned to be equivalent to one clock of the external clock CLK, parallelly inputted 2-bit data are successively and serially outputted. Thus, the rise and fall of the control signals tx and ty are easily controlled and a wide margin is secured. For instance, when one clock is 10n seconds, the rise and fall of the control signals tx and ty are controlled for every 5n seconds.
