Title: Flat spring in fiber reinforcing resin
Inventor: KAWATSU YUKIO
IPC: F16F1/368
Filed: 1977-12-06
Abstract: PURPOSE:To obtain a titled spring that has large connecting strength between a substrate and fitting portions and high mechanical strength as a flat spring and is particularly suitable for a truck and a passenger car. CONSTITUTION:This flat spring in fiber reinforcing resin is provided with a lamimar substrate 4 in carbon fiber reinforcing epoxy resin, which has the desired curvature, and fitting portions 5, 6 in said epoxy resin, which both surfaces are attached to both ends in the longitudinal direction of the substrate 4. Connecting portions  each consisting of wave forms, which mutually connnect as shown in the figure, are mounted to each connecting surface between the substrate 4 and the fitting portions 5, 6. Consequently, this device increases connecting area as compared to flat connecting surfaces as conventional flat springs while the connecting portions take partial charge of and are subject to shearing stress working to the connecting surfaces, thus remarkably improving connecting strength between the substrate and the fitting portions, then heightening mechanical strength as the flat spring.

Title: Picture reader
Inventor: MATSUNAWA MASAHIKO
IPC: H04N1/028
Filed: 1982-08-24
Abstract: PURPOSE:To obtain accurate picture information, by shifting the photodetecting plane of a photoelectric converting element, and sampling and holding the output of the photoelectric converting element when the photodetecting plane passes in the vicinity of a focal point. CONSTITUTION:When the photoelectric converting element 14 is shifted upward and downward with a driving section 15, the photodetecting plane of the photoelectric converting element 11 is vibrated between the front and the rear sides of a focal point. The output of the photoelectric converting element 14 is minimized at the focal point and increased before and after the focal point. Thus, a comparator in a picture signal output circuit 16 is set forward when the photodetecting plane of the photoelectric converting element 14 passes the focal point and an output of a delay circuit inputted in this case, that is, an output of the photoelectric converting element 14 at the focal point is sampled and held in a sample-and-hold circuit. Since the sample-and-hold value is revised one after another with the forward setting of the output of the comparator, the output of the picture reader gives accurate picture information.

IPC: G09G3/36
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce unnecessary output current of a source driver IC and to reduce power consumption by turning off a source driver IC output circuit during an unnecessary period. SOLUTION: According to this liquid crystal driving method, only during the write time Tw to a pixel, a source driver IC output circuit power supply is turned on, and during the store period Ts, the source driver IC output circuit power supply is turned off.

Title: Device for changing direction of air flow in blower
Inventor: NARIAI SHIGERU
IPC: F24F13/10
Filed: 1984-07-16
Abstract: PURPOSE:To make it possible to carry out the continuous change of an air flow direction by changing the air flow circuit of a casing utilizing the deformation property of a shape memory alloy. CONSTITUTION:In the case of a cooling mode operation, the slide portin 19 of a U- shaped wire shape memory alloy tends to open in a U-shape at the outdoor temperature, and produces a force outwardly pushing a wheel 11 along spokes 12, that is, a perpendicular force 23. This perpendicular force 23 is divided, as viewed from the side of the wheel 11, into a force acting in a radial outward direction, a central force 21 and a tangential force 22. Next, since indoor side is cooled, a U-shaped wire shape memory alloy 18 contracts, and the central force 21 is cancelled by a force acting on the opposite U-shaped wire shape memory alloy 18 positioned at the outdoor side and is distorted by delta. The tangential force 22 remains as a force to turn the wheel 11, and hence continuous rotation of the wheel 11 becomes possible. Thus, when the wheel 11 rotates continuously, the rotation thereof is transmitted to the rotating portion of an interrupting plate via a transmission belt 9. By the rotation of the interrupting plate 17, communication between respective blow-off ports and blast paths is cut off. Hence, change of air flow direction and change of blow-off ports such as blow-off in directions of arrows C and B and further blow-off in a direction of arrow A, can be carried out.

Title: Method for solidifying incineration ash
Inventor: FUJII KAZUTOSHI
IPC: F23J1/00
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To prevent an incineration ash from decaying after being dumped into a land to be filled by coating the incineration ash of a specified shape whose volume is reduced, with a water repellent. SOLUTION: About 5 wt.% of water are added as a binder to an incineration ash delivered from a reuse incinerator, and this mixture is kneaded and molded into a tablet under a molding pressure. Next, a polyethylene emulsion is applied as a water repellent to the tablet using a spatula. The water repellent to be used is an epoxy resin, asphalt or a paraffin wax is addition to the polyethylene emulsion. However, polyethylene is preferably used. In addition, the amount of coating when the polyethylene emulsion is used is 0.5-15 wt.% for the total amount of the incineration ash. Further, the incineration ash is molded into shapes such as rectangular parallelopiped, circular cylinder, sphere and charcoal ball.  Thus the incineration ash coated with the water repellent is left alone for about three days, then is soaked in pure water and the number of days to be spent until the molded incineration ash is decayed is measured. This molded incineration ash lasts for about 10-about 30 days without degradation compared to the life of a conventional ash molding lasting for only about 1-about four days.
