Title: Flow rate control valve
Inventor: KIDOUCHI YASUO
IPC: F16K31/06
Filed: 1990-07-05
Abstract: PURPOSE:To miniaturize the a valve by providing a control valve body for regulating a flow rate and a flexible pressure receiving body having a pressure receiving area equal to an opening diameter of a valve seat of the control value body, and balancing a primary pressure and secondary pressure of fluid between the control valve body and the flexible pressure receiving body. CONSTITUTION:A grooved diaphragm 13 serving as a flexible pressure receiving body 12 is connected to a control valve body 10 so that both a primary pressure and a secondary pressure can be balanced between the control valve body 10 and the flexible pressure receiving body 12. Accordingly, a small drive force can realize a driving operation, and further, a size of a solenoid 19 can be reduced. Since the diaphragm 13 is deeply grooved, an effective pressure receiving area of the flexible pressure receiving body 12 is kept equal to an opening diameter of a valve body 11 irrespective of a lifting quantity of the control body 10. Consequently, when the control valve body 10 is lifted so that a flow speed is increased, a static pressure applied to the control valve body 10 becomes low. Consequently, the pressure receiving area of the flexible pressure receiving body 12 becomes relatively large. Therefore, the control valve body 10 can be restrained from being lifted, thus resulting in an energizing quantity of the solenoid 19 to a flow rate thereof in the ratio 1:1 irrespective of the pressure.

Title: Muffler
Inventor: FUKUMORI AKIRA
IPC: F01N1/06
Filed: 1980-12-16
Abstract: PURPOSE:To enable silencing over a wide range of operation of an engine, by fitting an open area setting pipe slidably on an exhaust gas inlet pipe and by using the pressure of exhaust to change the open area of the exhaust gas expansion/contraction holes of the exhaust gas inlet pipe. CONSTITUTION:The exhust gas of an engine flows through a pipe 15 and the front 2 of a silencer 1 and enters into a pipe 5 having numerous holes 7. When the exhaust gas goes out of the holes 7, interference takes place in an expansion chamber. When the exhaust gas enters into a pipe 6 having holes 8, the gas contracts so that noises are eliminated. After that, exhaust gas is released to the outside through the rear 3. The pipes 5, 6 are an indentical pipe provided with a partition wall 13 inside. An open area setting pipe 10 is provided on the peripheral surface of the pipes 5, 6 to shut off the holes 7, 8. The open area setting pipe 10 is caused to slide by a diaphragm-type control valve driven by the exhaust pressure through a rod 18. When the engine rotates slowly and its exhaust pressure is low, the open area of the holes 7, 8 is reduced. When the engine rotates rapidly, the open area is augmented by the exhaust pressure to effectually eliminate a high-frequency range of noises.

Title: High pressure container
Inventor: HIROTA KAZUSHI
IPC: F16J12/00
Filed: 1980-12-17
Abstract: PURPOSE:To make it possible to easily insert a lid into a container body without making the gap between the container body and the lid large, by forming taper parts and flat parts in the contacting parts of the container body and the lid. CONSTITUTION:With a lid 2 being removed, a back-up ring 7 and a packing 6 are fitted in the mentioned order onto the lid 2, and as well a stopping ring 5 is screwed to the lid 2. The contacting parts 8 of a container body 1 and the lid 2 are formed with tapered parts 9 and flat parts 10. Then, the container body 1 and the lid 2 are gradually brought near together for inserting the lid 2 into the container body 1. Therefore, both are contacted together at their contacting parts 8 formed in the container body 1 and the lid 2. Since the lid 2 is inserted while their contacting parts 8 are contacted together, they are prevented from being contacted together in the vicinity of a high pressure sealing position where the pressure resistant mechanism is finally established. Accordingly, the gap between the container body and the lid may be made less.

Title: Opening-closing type optical switch
Inventor: TOMARU AKIRA
IPC: G02B6/12
Filed: 1982-10-12
Abstract: PURPOSE:To simplify the constitution and manufacture of an optical switching element, by using an elastomer element which shows distortion in shape when a voltage is applied as an optical switch material. CONSTITUTION:An optical switch 4 is composed of an elastomer 14 and transparent electrodes 15 and 16. A light transmits the elastomer 14 when no voltage is applied across the elastomer 14. Namely, the optical switch is turned on. When a voltage is applied across the elastomer 14, an electric field distribution is generated according to the unevenness of the transparent electrode 15 and unevenness is also produced on the elastomer element. When a light is passed through the elastomer 14 under this condition, the light is scattered by the unevenness of the elastomer and the transmitted quantity of the light is reduced. Namely, the optical switch is turned off. Therefore, when such an arrangement is made, an analyzer and polarizer which are used in the case of liquid crystal are not required and the elastomer element can be applied easily with a spinner, and, consequently, the constitution and manufacture of the optical switching element can be simplified.
