Title: Negative pressure releasing device
Inventor: TORII ERIKO
IPC: F04F10/00
Filed: 1986-04-29
Abstract: PURPOSE:To prevent the malfunction of a negative pressure releasing device using a float by mounting a valve chamber actuated by the inclination of a float rotating shaft on this shaft in the negative pressure releasing device for a liquid pump utilizing siphon action. CONSTITUTION:A float 1 forming a negative pressure releasing device is supported on a rotating shaft 5. When the level of oil sent by a liquid pump is low, a spherical ball 11 closes a hollow 7 of the rotating shaft 5, and when the said oil level rises to incline the float 1, the ball 11 separates from a 'O' ring 10 fitted in the hollow 8 to open the hollow 8. Therefore, air in a float cavity 3 is supplied to the negative pressure side of the liquid pump, namely, an oil carrying pipe through the hollow part 6 of the rotating shaft 5 and an air guide pipe 4 to instantly release the negative pressure. Consequently, negative pressure releasing action, namely, automatic stopping action for the liquid pump can be steadily made to improve its reliability.

Abstract: PURPOSE:To make it possible to stably and certainly perform paper feed, by feeding paper in a state contacted with the outer peripheral surface of a feed shaft while prescribing the compression amount of an O-ring by a pressure roller to the outer peripheral surface of the feed shaft langaging with the O-ring. CONSTITUTION:A feed roller 1 is constituted of a feed shaft 2 molded from a synthetic resin so as to have an outer diameter with good accuracy and an O- ring 3 while grooves 2a, 2b are provided to the outer peripheral surface of the feed shaft 2 in the peripheral direction thereof at plural places and O-rings 3a, 3b are inlaid with said grooves 2a, 2b so as to be protruded only by a predetermined amount DELTAd from the outer peripheral surface of said shaft 2. In paper feed, the O-rings 3a, 3b are pressed through paper 5 by a press roller 4 to be pressurized and deformed so as to flash the surfaces thereof with the outer peripheral surface of the feed shaft 2 and the feed amount of the paper 5 is determined by the precisely molded outer diameter of the feed shaft 2 and stable paper feed is performed by the friction force of the O-ring 3. By this mechanism, the numbers of parts are reduced and a structure becomes simple and paper feed becomes stable and certain.

Abstract: PURPOSE:To obtain an inexpensive stylus pressure applying device where the adjustment of stylus pressure is easy by using torsion springs as a stylus pressure spring and constituting the device so that the spring force of the stylus pressure spring, namely, the stylus pressure is adjusted with an adjusting screw. CONSTITUTION:A stylus pressure spring 7 is constituted with a pair of torsion springs connected by a U-shaped connecting part 7a, and torsion springs are inserted and set to the part of a vertical shaking shaft 6 of a shaft holder 3 from the left and the right, and the stylus pressure spring 7 is set to an arm holder 4 freely shakably in the horizontal direction by a horizontal shaking shaft 5. A pickup arm 2 tries to fall by moments of gravity of a cartridge 1 and the pickup arm 2 to charge one end of the stylus pressure spring 7. This charging force acts upon the tip of an adjusting screw 8 in the U-shaped connecting part of the stylus pressure spring 7 as a torsion repulsive force. That is, the quantity of engagement of the adjusting screw 8 with a female screw of the shaft holder 3 is adjusted to generate a desired stylus pressure counteclockwise with the balance between the moment due to the cartridge 1 and the pickup arm 2 and the repulsive force of the stylus pressure spring 7.

Title: Folding door
Inventor: MATSUDA KEIICHIRO
IPC: E05D15/26
Filed: 1995-03-31
Abstract: PURPOSE: To become intermediate folded-down posture automatically in a folded- down condition to enable stable running at the time of running by preventing opening and closing force from acting on two door plates from a position where the engagement of a click means is released to the intermediate folded-down posture. CONSTITUTION: An engaging recessed section 19a of a cam 9 is engaged with an engaging projection 16 thereof between a fully developed posture and an intermediate folded-down posture so that opening and closing force does not act. When a folding door is lightly closed for the folded-down posture after the engagement of the engaging recessed section 19a and the engaging projection 16 of two door plates 2 is released, the door plates 2 keep the intermediate folded-down posture and run stably. Next, when one of them which is in the intermediate folded-down posture at travel end is pressed, it is possible to make both door plates 2 into the completely folded-down posture easily against energizing force formed by an inclined cam face 19c and the engaging projection 16. Consequently, an object to be stored can be taken in and out easily and stable door-closed condition can be ensured.

IPC: H04H40/45
Filed: 1981-06-26
Abstract: PURPOSE:To eliminate deterioration in distortion and separation, by obtaining the multiplication output of a composite and a subcarrier signal component, and using the same power source for the determination of the amplitude of both the signals when demodulating a stereophonic signal. CONSTITUTION:An FM signal is supplied to a pulse counting detector 1, which generates a pulse position-modulated signal which has a composite signal frequency component, i.e. a PPM signal. This PPM signal is inputted to a switching circuit 5 through in-phase and out-of-phase amplifiers 14 and 15. On the other hand, a pilot signal contained in the PPM signal is extracted to generate a 38KHz sine-wave subcarrier signal by a sine-wave subcarrier generator 2. The sine-wave subcarrier signal is inputted to a switching circuit 5 through in-phase and out-of-phase amplifiers 29 and 30. Positive and negative power sources + or -V0 for in-phase and out-of-phase amplifiers 14 and 15 for obtaining the in- phase and out-of-phase signals of the PPM signal are used as a positive and a negative power source for an FF27, and as power voltage vary, the PPM signal and sine-wave subcarrier signal vary in amplitude.

Title: Floating of caisson
Inventor: TERAWAKI YUKIHISA
IPC: E02D23/02
Filed: 1987-04-24
Abstract: PURPOSE:To permit safe floating operation of a caisson to be performed by a method in which when a caisson sunk under water is to be floated, the pressure of air to be expanded with variations in the pressure of water as floating occurs is reduced. CONSTITUTION:A cover 3 is attached to the upside of a caisson 1 sunk under water, and the caisson 1 is floated up while discharging water in the chamber of the caisson by the pressure of compressed air supplied into the caisson. In this case, the caisson 1 is floated up while reducing the pressure of air in the caisson to be expanded by variations in the external water pressure with floating to almost the same extent as the external water pressure. The acceleration of the floating speed can thus be avoided and the scattering or the cover 3 due to the high pressure, can also be prevented. Safe floating of the caisson 1 can be attained.

Abstract: Apparatus and method for using a compressed gas in an aerosol spray system to produce and maintain an effective aerosol spray includes the use of an aerosol spray valve 4 for emitting the aerosol spray. A dip tube 18 is coupled to the valve 4 and extends into the spray system. The tube 18 has an upper portion which is substantially airtight above an initial liquid level 14. A lower portion of the dip tube 18 extends below the initial liquid level 14 and has a liquid entrance hole 24 substantially at the bottom thereof. A vapor tap hole 26 is provided in the dip tube 18 above the liquid entrance hole 24 and below the initial liquid level 14. The vapor tap hole 26 allows compressed gas 16 to enter the tube 18 and mix with the liquid 20 therein when the liquid level 28 has fallen below the vapor tap hole. Even after the pressure has fallen, the mixing of the compressed gas 16 with the liquid 20 in the dip tube 18 substantially reestablishes the deteriorated spray characteristics to produce an effective aerosol spray.
