IPC: F02B53/08
Filed: 1982-10-27
Abstract: PURPOSE:To enable to raise the charging efficiency of an engine effectively, by transmitting compression wave produced when a low-load intake port of one cylinder is closed to a low-load intake port of the other cylinder just before it is closed completely via a low-load communicating passage at the time of high- speed operation of the engine. CONSTITUTION:The opening periods of high-load intake ports 4 and low-load intake ports 3 of cylinders 1A, 1B are set respectively at 270-320 deg. and 230- 290 deg., and high-load intake passages 21a and 21b are communicated with each other via a connecting passage 25 while low-load intake passages 20a and 20b are communicated with each other via a connecting passage 27. At the time of high-speed operation of an engine, compression wave produced when the high- load intake port 4 of one cylinder is opened is transmitted via the connecting passage 25 to the intake port 4 of the other cylinder just before it is closed completely, and similarly, compression wave produced when the low-load intake port 3 of one cylinder is closed is transmitted via the connecting passage 27 to the intake port 3 of the other cylinder, whereby the engine is supercharged. Therefore, it is enabled to raise the charging efficiency of the engine and hence to increase the output efficiently with no use of a supercharger.

Title: Precipitation tank for floating-type waste water treatment apparatus
Inventor: NAKAMURA TEIJI
IPC: B01D21/24
Filed: 1990-07-17
Abstract: PURPOSE:To prevent the solid-liquid separating effect in a precipitation tank from lowering and easily install a highly functional waste water treatment apparatus in a floating structure by uniformly causing overflow in all the circumference of an overflowing gutter constantly even if a precipitation tank of the waste water treatment apparatus is tilted. CONSTITUTION:Overflowing water flows in an overflowing gutter 1 through overflowing holes 10 formed in its circumference and there are a float 2 on each upper side of the overflowing gutter 1 and a balance tank 3, in which overflowing water from the overflowing gutter 1 in the opposite flows, in the lower side and a pipeline through which the overflowing water is stored once in the balance tank 3 and discharged out of the precipitation tank and the floating-type overflowing gutter 1 having a structure like this is fixed in the upper side. Owing to the structure, even if the precipitation tank of a waste water treatment apparatus tilts, overflow occurs uniformly in the all circumference of the overfloawing gutter constantly and thus solid-liquid separation effect in the precipitation tank does not lower. As a result, a highly functional waste water treatment apparatus is installed easily in a floating structure.

Title: Production of partition wall for cell of gaseous oxygen detector
Inventor: YANAGIDA HIROAKI
IPC: A61B10/00
Filed: 1983-10-12
Abstract: PURPOSE:To enable specification of the thickness of a partition wall of a solid electrolyte spread on a base plate by placing an org. film on the partition wall material of said solid electrolyte and pressurizing the same. CONSTITUTION:About 10mol% stabilizer such as Y2O3 and about 2wt% a sintering accelerator such as Fe2O3, Al2O3 or the like are added and mixed to and with zirconia and an org. binder is mixed therewith. The mixture is spread on a base plate of ceramics, glass, metal, etc. to form a uniform layer. The spread layer prior to calcination is once temporarily calcined for about one hour at about 600 deg.C to sublimate and disspiate the org. binder so that only the layer material is left on the base plate. An org. film is then placed thereon in contact with the surface of the temporally calcined layer and is pressurized with a mechanical press to reduce the thickness of the layer to 1-100mum. The layer prior to calcination taken out of the mechanical press is stripped from the base plate and is calcined for 1-5hr at 1,000-1,800 deg.C, by which the solid electrolyte partition wall consisting of zirconia is obtd. The solid electrolyte partition wall constituted in such a way is as thin as 1-100mum and therefore the electric resistance thereof is low and the operating temp. is made low.

Title: Tracking device for rotating magnetic recording body
Inventor: ITOU HARUO
IPC: G11B21/10
Filed: 1983-10-14
Abstract: PURPOSE:To reduce the possibility of the influence of a signal dropout in reproduction by performing tracking control on the basis of a newly read and detected envelope level when a reproducing head almost arrives at nearly of a peak of an envelope. CONSTITUTION:A video signal detected as the head 26 is fed is inputted as an envelope waveform 250 to an ADC46. A controller 100 performs envelope level detection and level comparison each twice at two envelope detection positions H3 and H4 near a peak of the envelope. Namely, it is possibly decided that there is no significant difference because of a dropout of a video signal generated temporarily owing to a failure in contacting when the head 26 reads the video signal from a track. Then, this dropout is prevented from exerting influence upon the tracking control.
