Patent number: 7390039Abstract: A bumper absorber for protecting pedestrians is formed into a W-shaped cross-sectional configuration, as taken along a direction which is orthogonal to a longitudinal direction of the bumper absorber. The W-shaped cross sectional configuration has portions in which a front notch portion, an upper rear notch portion, and a lower rear notch portion overlap with one another in a vertical direction of a vehicle. Ribs are formed respectively at the upper rear notch portion and the lower rear notch portion, and a triangular notch is formed from a vehicle rear side at each of the rib. Further, the ribs 30 are formed at the upper rear notch portion and the lower rear notch portion so as to be separated from each other at predetermined intervals in a longitudinal direction of the bumper absorber, namely, in a transverse direction of the vehicle. With this structure, a rise in impact load acting on a pedestrian who is hit by a bumper can be controlled.Type: GrantFiled: April 23, 2007Date of Patent: June 24, 2008Assignees: Sekisui Kaseihin Kogyo Kabushiki Kaisha, Kabushiki Kaisha ChugaiInventors: Junji Adachi, Naruaki Abe, Fumihiko Sato, Taku Fukuyama, Kouji Mori, Yoshikatsu Miwa, Yukiya Morita

Patent number: 5435098Abstract: A water culture apparatus wherein air space sections are formed between plant containers and a nutrient solution when rafts are floated in a water culture tank filled with the nutrient solution. The plant containers are inserted in vertically oriented channels provided in the raft. The air space sections are formed in order that the plant containers do not get submerged in the nutrient solution. The plants are cultivated by: gradually moving the raft from one end to another end of the water culture tank, movement of the raft corresponding to a state of growth of the plants so that the plants supported by the plant containers reach the other end by the time the plants have grown as a result of having absorbed nutrients from the nutrient solution; and harvesting the plants when each of the rafts reaches the other end of the water culture tank.Type: GrantFiled: August 2, 1993Date of Patent: July 25, 1995Assignee: Sekisui Kaseihin Kogyo Kabushiki KaishaInventors: Koshi Koide, Miyoji Hikida

Patent number: 5421982Abstract: An electrically conductive polymer gel is composed of a crosslinked polyacrylamide polymer including an electrolytic salt, water and a polyhydric alcohol uniformly dissolved therein, wherein the water and the polyhydric alcohol are major components of said polymer gel. The polyacrylamide series polymer in the gel has properties of being hydrophilic and being a nonelectrolyte. Therefore, a desirable connection between the gel and the electrode can be achieved with low impedance. Moreover, the polyhydric alcohol reduces the drying speed of the electrically conductive polymer gel, thereby preventing an increase in the impedance due to the dryout of the gel. Therefore, the electrically conductive polymer gel of the present invention permits an accurate measurement of an electrical phenomenon in an organism for long periods of time.Type: GrantFiled: September 13, 1993Date of Patent: June 6, 1995Assignee: Sekisui Kaseihin Kogyo Kabushiki KaishaInventors: Toshiki Ikeda, Yoshikazu Kobayashi, Shuichi Sasahara, Takashi Higashi

Patent number: 5414241Abstract: A heater includes a heating element made of a PTC thermistor, electrodes formed on upper and lower surfaces of the heating element, flat metallic terminals connected to the electrodes, lead wires connected to inner surfaces of the metallic terminals that face each other, and an insulating case for covering exposed portions of the heating element, electrodes, and of the metallic terminals, and the connections between the lead wires and the metallic terminals. With this structure, since no bumps are produced on the outer surfaces of the metallic terminals by connecting the lead wires to the metallic terminals, the thickness of the insulating case over the metallic terminals is reduced. This allows a reduction in the thickness of the heater and an improved heat transfer between the heating element and the heated object.Type: GrantFiled: May 3, 1993Date of Patent: May 9, 1995Assignee: Sekisui Kaseihin Kogyo Kabushiki KaishaInventors: Keiichi Ohashi, Yoshinobu Ohara, Fumitaka Ishimori
