Title: Flame cylinder of kerosene stove
Inventor: NAKAMURA KAZUHARU
IPC: F23D3/04
Filed: 1981-12-23
Abstract: PURPOSE:To uniformly red-heat an inner and an outer flame cylinders, and to obtain long and  white-yellow flames, by designing flame cylinders so that the draft power, passing through the  gap between the outer flame cylinder and a diathermanous casing cylinder, is stronger than  that passing through the gap between the inner and the outer flame cylinders. CONSTITUTION:The height of the upper edge of an inner flame cylinder 1 is designed so as to  be lower than the fitting position of the cover plate 6 of an outer flame cylinder 2, provided to  the upper edge of an outer flame cylinder 2. The inside edge of the cover plate 6 of an outer  flame cylinder 2 is located in the position above the top edge of an inner flame cylinder 1,  while the top of the gap between the outer flame cylinder 2 and a diathermanous casing cylinder 3 is closed by contacting the outside edge of the cover plate 6 with the diathermanous casing cylinder 3. The total open area of breather pores 2' in the upper part of an outer flame  cylinder 2 is designed to be larger than that in the other part thereof. With such an arrangement, the draft power passing through the gap between the inner and the outer cylinders 1 and  2 is not able to become stronger than that flowing along the outer side of an outer flame cylinder 2. As a result, the lower parts of an inner and an outer flame cylinders 1 and 2 are  both uniformly red-heated, and long and white-yellow flames can be obtained from the under  part of a flame spreader part 5 which is positioned on the top of both flame cylinders.

Inventor: FURUKAWA OSAMU
IPC: G01M17/007
Filed: 1982-12-08
Abstract: PURPOSE:To inform a driver of the advancing direction of a vechile during the turning thereof as visual information by detecting the speed (v) in the advancing direction thereof and the speed V in the transverse direction thereof during the turning thereof to calculate a skid angle beta thereof by beta=v/V. CONSTITUTION:The angle beta of the arrow D as indicating the ongoing direction during the turning of a vehicle to the widthwise center line C thereof refers to the skid angle of a vehicle. When the speed in the transverse direction of a vehicle is expressed by (v) with respect to the speed thereof during the turning thereof, namely, the speed V in the advancing direction, the skid angle beta of the vehicle almost meets beta=v/V. So, both the variables (v) and V are detected with a vehicle speed sensor and a transverse speed sensor to compute beta=v/V with a computer and according to a value outputted, a ongoing direction indicator is controlled. In this manner, a driver can be informed of the advancing direction of the vehicle during the turning of a vehicle as visual information.

Title: Lead storage battery
Inventor: HATANAKA TERUHIRO
IPC: H01M4/16
Filed: 1981-12-25
Abstract: PURPOSE:To improve the capacity and life, etc. of an electrode plate by adding proper sulfuric acid to lead powder or fine powder material of lead oxide, etc. and by granulating and filling them into a coarse braided glass tube. CONSTITUTION:A fine powder material of lead oxide of some 1-10mu containing 25% of metal lead powder is mixed with dilute sulfuric acid, and the mixture is granulated into grains with a diameter of 0.1-3.0mm. by a granulating machine. The lead grains thus produced are next filled in gaps 4 between a coarse braided glass tube 8 and lattice core metals 2 made of lead or lead alloy. Since the size of lead grains is large in such an electrode plate, the peeling quantity of an active material is small, and as a result the life performance is improved. In addition, since the mesh of the tube is coarse, the infiltration of an electrolyte into the electrode plate is improved, and furthermore the electrolyte easily infiltrates into the inside of the electrode plate through gaps among grains, thereby the utilization factor of the active material is improved. Particularly, this effect is greater at a higher rate discharge where the diffusion of the electrolyte controls the capacity.

Title: Cable inlet sealing member
Inventor: OGATA KAZUYA
IPC: F16L5/02
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of gaps, such as delta voids, and improve the reliability of seal by inclining a portion that divides the deformed layer of a slit for inserting a cable into an insertion hole at an angle, other than perpendicular, to a surface facing the cable inlet in the deformed layer or an insertion surface. SOLUTION: A fin-like internal projection 20 protruded toward the opposite side through a slit 13, is formed on internal bent portions 19. Meanwhile, a similar fin-like external projection 22 is formed on external bent portions 21. As a result a cable inlet sealing member 10, when fit between a cable inlet 14 and a cable 11, fills the gap between both the internal bent portion 19 and the circumference of the cable 11 with the internal projection 20, and fills the gap between both the external bent portion 21 and the cable inlet 14 with the external projection 22. The cable inlet sealing member 10 thereby brings deformed layer 18 into tight contact with the outside surface of the cable 11 and the inside surface of the cable inlet 14. This prevents the formation of gaps, such as delta voids, and improves the reliability of seal.
