Abstract: PURPOSE:To provide the method of which the execution is easy and by which a widened road with great strength is constructed. CONSTITUTION:A ground beam-shaped support 4 continuous with the course of a road is formed in the valley side of an established road 1. A counterweight 5 continuous with the course of the road is formed in the mountain side of the established road 1. An overhanging girder 7 is placed on the counterweight 5 and the support 4 and part thereof is overhanged to the downgrade side thereof. The end part of the upgrade side of the overhanging girder 7 is fastened onto bolts 6 projecting on the counterweight 5. A form 12 is suspended from the overhang of the overhanging girder 7 and hardening materials 13 are placed and thus a newly established road is constructed. When vehicles pass through on the road, their loads are applied to the support 4. However, the loads are distributed since the support 4 is in contact with the newly established road, on a beltlike surface. Therefore, such a matter that a large load is applied only to part of the newly established road, does not occur. The execution of the counterweight 5 is extremely easier than the large-scale placing of anchors and the overhanging girder 7 can be easily fastened at any place, with the bolts 6 or the like.

Title: Sorter for powdery body
Inventor: KOGUCHI MAKOTO
IPC: B03C7/02
Filed: 1981-09-02
Abstract: PURPOSE:To separate and sort particles in response to their components with high accuracy, by forming a solid wall from the material which gives priority to the collision of the particles with the solid wall at a frictionally electrified part, and introducing the particles together with turning stream-forming gas. CONSTITUTION:When impalpable particles fluidized by proper gas such as air or inert gas is supplied through a supply pipe 21 into a cylindrical vessel 23, the gas forms a high-speed turning stream at the upper side of the vessel and flows out through an outflow pipe 22. On the other hand, the particles are moved to the wall surface of the cylindrical vessel 23 by the centrifugal force of the turning stream of the gas, and a spiral stream along the arrow 26 is formed by the turning stream formed from the upper part to the lower part of the vessel 23. At this time, the particles are brought into contact with the wall surface and charged with electricity by friction. Since the vessel wall is made of copper, fluororesin or the like, the particles preferentially come into collision with the vessel wall surface without collision with each other and discharged through a particle outlet 24.

Title: Transmission gear
Inventor: OOTA YOSHIMI
IPC: F16H61/10
Filed: 1985-06-24
Abstract: PURPOSE:To prevent a gear sound in a transmission when it performs speed change operation, by providing a timing difference so that a shifter is placed in a transmission-off position only after a clutch is completely disconnected. CONSTITUTION:A transmission gear, connecting a pilot control circuit 39 with a transmission case, controls the third control valve 26 to be placed in a clutch disconnected position. However, the transmission gear, before a clutch is placed in a completely disconnected condition, generates the existence of meshing friction of a shaft gear 33 with a transmission gear 51a and relative movement between a shifter 17 and an oil hydraulic piston 19. Accordingly, the transmission gear, placing the shifter 17 to be left in a transmission connected position (ON) in no relation to urging force of a spring 35a placed in a resiliently deformed condition, prevents a gear sound from generating when a speed change shift control is performed.

Title: Production process for fluorescent lamp
Inventor: HAGIWARA MAKI
IPC: H01J9/22
Filed: 1982-08-11
Abstract: PURPOSE:To uniformalize the film thickness between the upper and the lower parts of a glass tube, by drying almost the upper part of the glass coated with a phosphor, then letting flow away the amount of aqueous paint in the lower part of the glass tube through stopping the air blow for drying for a while, and afterward again starting the blower drying. CONSTITUTION:A phosphor aqueous paint is applied from the upper part onto the internal surface of a glass tube which is vertically held, thereafter a hot blast is sent from a blow nozzle 1 in order to dry a phosphor film while the glass tube is held by a tube chuck 2. For 1-3min of the beginning, the hot blast is sent at the flow rate of 50-120l/min and at the temperature of 60-90 deg.C to dry the glass tube. Next, the air blow is completely stopped and the excess amount of the aqueous paint between the middle part and the lower part of the glass tube is forced to flow down to adjust the distribution of the film thickness. If the period of stop thereof is long, the film thickness of the middle part becomes too small; so said period of stop is desired to be practically 1-3min, preferably 1-2min. After that, the drying is continued by sending the same hot blast which is used for drying the upper part. In this case, forced drying caused by thermal radiation using a gas burner or the like from the external surface (side face) of the glass tube may be also used together with the above drying in order to shorten the total drying time required.
