Title: Internal combustion engine with rotary reciprocating piston
Inventor: TANIGAWA HIROYASU
IPC: F02B57/00
Filed: 1984-09-26
Abstract: PURPOSE:To assure an internal combustion engine undergoing high rpm rotation without vibration by rotating an engine body by making use of waste gas wasted from the engine adapted to arrange a pair of pistons holding a central combustion chamber therebetween. CONSTITUTION:A pair of pistons 10 are housed in a cylindrical engine body 1 in a confronting relation while holding a central combustion chamber 2 therebetween. An exhaust hole 4 and scavenging hole 6 are formed through a combustion chamber 2, while an air intake chamber 12 is provided externally of the pistons 10. Said chamber 12 is communicated with the scavenging hole 6 via an air intake hole 7. Furthermore,an outlet of the exhaust hole 4 is bent in a direction of a tangential line of the chamber to form a nozzle 5, and a bucket is formed on an engine body 1 around an outer periphery of said nozzle integrally with the engine body while leaving an interval for interposing a stationary blade (not shown). The pistons 10 are reciprocated and rotated by making use of explosion force of compressed mixture gas in the combustion chamber 3 through a sparking plug 3 of the engine, and rotary force of the pistons as well as rotary force of the bucket 13 produced due to exhaust gas pressure injected from the nozzle 5 are utilized for power to drive the engine.

Title: Ophthalmic imaging apparatus
Inventor: MATSUMURA ISAO
IPC: A61B3/14
Filed: 1988-08-12
Abstract: PURPOSE:To obtain an eyeground image easy in the contrast with the visual field data measured by a perimeter by mounting a means capable of being inserted in and removed from an imaging light path and performing the mirror reversal of an image to an imaging system. CONSTITUTION:The ring slit light emitted from an illumination optical system 11 is reflected by a perforated mirror 2 to form a ring slit image in the vicinity of the iris of an eye E to be examined by an objective lens 1 and illuminates the eyeground Ef. When a reversal mirror 8 is moved to be inserted in a light path, a projection lens 9 and a film surface 10 are also moved, and a projection lens 9' and a film surface 10' are positioned in the reflecting direction of a reflecting mirror 8'. The light transmitted through a field lens 7 is reflected by the reversal mirror 8 to be subjected to mirror reversal and formed into an image on the film surface 10' by the projection lens 9'. Therefore, when the eyeground image Ef is an erected image, an inverted eyeground image Ef'' subjected to mirror reversal in an up-and-down direction is obtained. Therefore, the contrast with the visual field chart data measured by a perimeter becomes extremely easy because the image directions of both of them coincide with each other in up-and-down/left-and-right directions.

Title: Culvert generator
Inventor: UEDA KAZUNARI
IPC: E02B9/08
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To generate electricity while conserving energy, by making a culvert in a hollow place on the land between the seas, communicating the both ends thereof to the seas through the water passage and rotating the water wheels disposed in the water passage with the sea water flow as power which moves because of the rise and fall of the tide. SOLUTION: A culvert 6 is made in a hollow space on the land between the seas, such as a narrow place on the land around Mexico between the Pacific and the Atlantic, with the both ends thereof communicating to a sea 10 through a water passage 4. Although the tides become high and low on the sea 10 affected by the moon gravity, the tides change reversibly in the American Continent separated by the Pacific and the Atlantic. Therefore, when a culvert is made around Mexico, communicating to the sea via a water passage, the tide flow is formed. The energy of the tide flow rotates a water wheel 1, and the rotational force drives a generator 3 to generate electricity.

On a reception- side, control circuits 15-1 to 15-n sweep wavelength variable filters 7-1 to 7-n and the wavelength of a signal received for detecting the required channel from the wavelength-divided/multiplexed signal is detected at first. When the signal is detected, channel ID is extracted from the overhead signal of the frame in the electric signal stage, and comparison parts 14-1 to 14-n compare whether it is matched with the required channel or not.  When they are not matched, the filters are swept furthermore, and an operation is repeated.
