Title: Intake apparatus for rotary piston engine
Inventor: HIRATA NOBUO
IPC: F02B27/00
Filed: 1982-10-27
Abstract: PURPOSE:To enable to raise the charging efficiency of an engine, by transmitting compression wave produced in a high-load intake passage when a high-load intake port of one cylinder is closed to a high-load intake port of the other cylinder just before it is closed completely via a connecting passage at the time of high-load 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. in respect of the angle of rotation of eccentric shafts 8. Further, high-load intake passages 21a, 21b are communicated with each other via a connecting passage 25, and an expansion chamber 28 is formed in a low-load intake passage 20. At the time of high-speed operation of an engine, compression wave produced in the intake passage when the high- load intake port 4 of one cylinder 1A or 1B is closed is transmitted via a connecting passage 25 to the high-load intake port 4 of the other cylinder just before it is closed completely. At the same time, expansion wave produced at the time of starting intake of air at the low-load intake port 3 is inverted in the expansion chamber 28 and its secondary pulsation waves are transmitted to the intake port 3 just before it is closed completely, whereby the engine is supercharged. Thus, it is enabled to raise the charging efficiency effectively with no need of a supercharger.

Title: Microscope observation device
Inventor: SUZUKI TOSHINOBU
IPC: G02B21/06
Filed: 1990-07-18
Abstract: PURPOSE:To make an image not dark, to facilitate the manufacture, and to prevent a double image from being formed by constituting the observation device so that reflected light from the opposite surface to a translucent surface exits from a visual field. CONSTITUTION:The translucent surface 3a of a translucent member 3 and the opposite surface 3b are made not parallel and then the harmful light reflected by the surface 3b travels in a completely different direction from image forming light reflected by the surface 3a, namely, exits from the observation visual field. The transmissivity of the surface 3a need not be made low and bright downward lighting is obtained. Consequently, the image does not become dark. The wedge angle of the member 3 is set only so that the harmful reflected light exits from the visual field, so the tolerance of the wedge angle may be relatively large and the manufacture is therefore easy. Further, only the reflected light of the image forming luminous flux from the surface 3a of the member 3 becomes regular luminous flux and the harmful light can be removed completely, so good view is obtained.
