Title: Optical image forming system

Filed: 1994-05-16
Abstract: PURPOSE:To remove the influence of a zero-order light beam by a simple method by setting the picture display plane of a picture display element i.e., a displayed picture shifted from the optical axis of a diffraction type optical element. CONSTITUTION:An illuminating light beam 103 emitted from a light source becomes a parallel illuminating light beam 107 by means of a collimator lens 105 and illuminates a transmission type input display picture 109 from behind. A signal light beam 111 modulated by the input display picture 109 becomes a diffracted beam by means of a Fresnel zone plate 113 as an image forming lens, propagates to an image forming plane 117 and the image formed picture 119 of the input display picture 109 is obtained. In this case, the input display picture 109 is set on the upper half position of the optical axis 121 of the Fresnel zone plate 113. Consequently, the image formed picture 119 is formed on the lower half position of the optical axis 121. On the other hand, the zero- order light beam 123 passing through the Fresnel zone plate 113 without being diffrected propagates as it is through a space and arrives at the upper half position of the axis 121 on the position of the image plane 117.

Title: Metal joint for hose
Inventor: KOZUKA HAJIME
IPC: F16L33/20
Filed: 1990-04-17
Abstract: PURPOSE:To prevent generation of bulge in a metal joint for high pressure hose used in automobile and various industry by providing a one or more annular channel-shaped groove on the outer circumference of a nipple, and inserting therein a resilient ring member having a smaller wall thickness than the groove. CONSTITUTION:An angle-shaped protrusions 27 are formed on the outer peripheral surface of a nipple 21, while an annular channel-shaped groove 29 having a width of about 1-5mm and a depth of about 0.1-3mm is formed on a force end 28 side being the insertion end of a hose 25. A ring member 31 in a prism shape in section having a gap 32 between an upper part and a side face is fitted in the groove 29. When the hose 25 is fastened between the nipple 21 and a sleeve 23 further, the compressed amount of rubber is absorbed by the gap 32 above the resilient member 32, and then also absorbed by the compression deformation of the resilient ring member 31. Though the compression stress is slightly alleviated, the compression stress is maintained as the repelling force acts on the ring member 31 against a swelling part 33, and thereby improving durability of seal performance.

Abstract: PURPOSE:To reduce the size of a solenoid valve by increasing the driving force at the moment of open valve. CONSTITUTION:A valve rod 11 for driving a valve body 7 in the open valve direction is coupled to said valve body 7. A core 21 and an exciting coil 14 fitted over the core 21 are fixed concentrically with the valve rod 11.

The valve body 7 is engaged with the valve rod 11 such that it is driven in the open valve direction while resisting against the resiliency of a spring 10 by the repelling force being produced against the core 21 through conduction of power to the exciting coil 14. With such arrangement, the size of the exciting coil can be reduced thus reducing the size of a solenoid valve.

IPC: F01N1/02
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To dampen vibration of a low frequency in which columnar resonance is generated in an exhaust discharging pipe by a resonance chamber by allowing the intermediate part of the exhaust discharging pipe to communicate with the resonance chamber in a device formed in such a constitution that the inner part of a muffler is divided into the resonance chamber and an expansion chamber and exhaust gas is discharged from the exhaust discharging pipe through the expansion chamber. SOLUTION: When an engine is rotated at a low speed at the time of acceleration, exhaust gas from an internal combustion engine is led from an exhaust leading-in pipe 18 into an expansion chamber 12. At this time, a control valve 26 is closed since an exhaust gas rate and exhaust pressure are low. Exhaust gas is led into the expansion chamber 14 through a connecting pipe 20, and it is discharged from the expansion chamber 14 through an exhaust discharging pipe 22. At this time, only pressure wave is led to a resonance chamber 16 through a communicating pipe 28.  In the relation to the resonance chamber 16 and the communicating pipe 28, the capacity of the resonance chamber 16 and the length of the communicating pipe 28 are regulated so as to dampen vibration caused by columnar resonance generated in the exhaust discharging pipe 22, and thereby, columnar resonance generated in the exhaust discharging pipe 22 is suppressed.

Abstract: PURPOSE:To prevent a vane from causing its chattering phenomenon when a compressor is started, by providing a changing means of flow path sectional area, which increases the flow path sectional area while the compressor is stopped larger than that while the compressor is operated, in an oil passage communicated from an oil separator to a vane groove. CONSTITUTION:A throttling device 21 is provided in a passage communicated from an oil separator to a vane groove. If the pressure in a chamber is balanced when operation of a compressor is stopped, a ball 25 in the throttling device 21 drops down to a position 33, placing an oil path under a throttled condition. If the compressor is started, oil accumulated in a bottom part of the chamber is allowed to flow into a communication hole 24 because gas is compressed by jumping out a vane. Here the ball 25 is floated in the direction of a communication hole 20, and the oil is allowed to flow in a wide flow path, consisting of a space between the ball 25 and the communication hole 24 and a groove 31, reaching a back face of the vane. Accordingly, the vane is prevented from causing its chattering when the compressor is started.
