Title: Coupling
Inventor: KURIBAYASHI SADATOMO
IPC: F16H1/14
Filed: 1985-12-23
Abstract: PURPOSE:To obtain a coupling simple in structure, which can selectively change normal rotation of an input shaft into normal rotation, reverse rotation or non-rotation of an output shaft by using a planetary gear as a device for transmitting rotation of the input shaft to the output shaft. CONSTITUTION:An output side bevel gear 4 is coaxially disposed opposite to an input side bevel gear 3 to which a disc 9 is fixed. A support rod 7 is fixed to a sleeve 12 rotatably fitted in a projecting portion 2E of an output shaft and arranged in the diametral direction of the output shaft. The support rod 7 is provided with pinions 5, 6 engaged with the bevel gears 3, 4 and an outer ring 8. When the outer ring 8 is fixed to the disc 9, the rotation of an input shaft 1 is transmitted to the output shaft 2 through the bevel gear 3, so that the output shaft is normally rotated. When the outer ring 8 is fixed to a frame 11, the normal rotation of the bevel gear 3 causes the reverse rotation of the bevel gear 4 through the pinions 5, 6 so that the output shaft 2 is rotated reversely. When the outer ring 8 is freely rotated, the pinions 5, 6 revolve round the output shaft 2 so that the bevel gear 4 is not driven. Accordingly, the normal rotation of the input shaft 1 can be selectively changed into normal rotation, reverse rotation or non-rotation of the output shaft 2.

Title: Diving buoyancy tool with respiratory apparatus
Inventor: YAMAMI NOBUO
IPC: A62B9/06
Filed: 1994-10-19
Abstract: PURPOSE: To use the air inside of a diving buoyancy tool for respiration when air becomes insufficient in water by installing a respiratory apparatus to the shoulder part of a diving buoyancy tool. CONSTITUTION: When a diver tries to get the air of a diving buoyancy tool 1 in water, first he takes a standing posture, gathers the air inside of the diving buoyancy tool 1 around the part of the shoulder, and adds a mouthpiece to the mouth. Next, he pushes a button 6, and after inspiring water in the mouthpiece into the diving buoyancy tool 1 in the expiration, he begins to absorb. The exhalation is vomited toward the water, and this is repeated. Because the air inside of the diving buoyancy tool 1 expands when the diver continues to surface, the volume of the air which can be used continues to increase. Even if the air becomes insufficient in diving with large depth, the possibility of survival becomes high.

Title: Control for fluid control valve
Inventor: OZAKI YUKINORI
IPC: F16K31/06
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To restrain the consuming power of a drive means for a small capacity of a battery power source by measuring the flow rate of fluid passing through a flow passage, and changing driving voltage according to the force necessary to conduct opening and closing actions with a voltage control means which permits the measured signal to be inputted for the operation of the drive means, thus conducting the opening and closing control of a valve part. SOLUTION: The valve element of a valve part 11 is generally in an opening condition. Flow rate is measured, and based on the measured value, an arithmetic processing part 14 conducts flow rate integration, which is compared with a preset value, and if the integrated value is large, it is discriminated as failure to output a valve closing signal and apply voltage to a stepping motor 12. The rotation of the stepping motor 12 is converted into linear movement by a linear movement converting part. The valve element is brought into contact with a valve seat to form a valve closing condition. When no failure is discriminated, a valve opening signal is outputted, and voltage is applied to the stepping motor 12 to obtain a valve opening condition.  During valve closing movement, the pressure by gas flow is received by the valve body in the valve closing direction, thus it is possible to drive the valve element at low voltage.

Title: Acceleration detector
Inventor: YASUKAWA TAKESHI
IPC: G01P15/18
Filed: 1986-12-09
Abstract: PURPOSE:To reduce a size and a weight by filling a non-magnetic fluid in a hermetically sealed container made of a non-magnetic material, floating a magnetic sphere in the non-magnetic fluid and arranging a pressure detector in contact with the hermetically sealed container on its central axis. CONSTITUTION:A non-magnetic fluid 2 is filled in a hermetically sealed container 1 made of a non-magnetic material. A magnetic sphere 3 is located in the fluid 2 in floating condition. Pressure detectors 4 and 4' are provided on the opposite outer wall surface portions of the container 1 on the central axis X-X' of the container 1. Further, arm portions 5 and 5' extending from the opposite inner wall portions toward central portion are provided. When an acceleration acts on the right hand on the axis X-X', the sphere 3 is moved to the left to be pressed against the arm portion 5'. In result, since pressure proportional to the acceleration acts on a wall surface and the pressure is applied to the detector 4', output proportional to the acceleration is generated in the detector 4'. When the detectors 4 and 4' are combined to a differential circuit, the value of the acceleration can be judged from the magnitude of the differential output of the differential circuit and, at the same time, the direction of the acceleration can be judged from the polarity of the differential output.
