Title: Coupled rolling diaphragm type propellant tank
Inventor: JIYON EI HAADOGUROOBU
IPC: F02K9/50
Filed: 1994-09-08
Abstract: PURPOSE: To increase the tank capacity efficiency of missile propellants by forming a piston out of a flexible piston, and forming the flexible piston and an outer diaphragm in a single integrally formed assembly. CONSTITUTION: A flexible piston 20 is provided to have a thickness tapered to an outer diaphragm 23 between a center portion and an outer peripheral portion and thereby a sectional profile constituting a surrounding piston portion larger in flexibility than the center portion. This piston 20 and the outer diaphragm 23 are made of metal and formed in a single integrally formed assembly. The initial position of the piston 20 is located in a dome-shaped inlet end and, by storing propellants at least in a part of an inlet end 3, the propellant capacity of a tank 1 is increased. In addition, the thickness of the piston 20 is tapered between the center portion and the outer peripheral portion, and thereby even the thickness of the outer diaphragm 23 is also reduced. Thus, the sectional profile constituting the surrounding piston portion more flexible than the center portion is provided.

Title: Muffler
Inventor: NOGUCHI YOSHIHIRO
IPC: H02K5/24
Filed: 1990-08-16
Abstract: PURPOSE:To miniaturize the device, and also, the improve the sound absorbing/muffling effect by constituting a spiral shape muffler by an air course wall consisting of a sound absorbing material, and providing a back air layer along this spiral air course wall. CONSTITUTION:When a blower motor 2 is operated, exhaust air of the blower motor 2 passes through an air course 10 and is exhausted into the open air from an exhaust port 17. In such a case, noise of the blower motor 2 is also propagated in the air course 10 together with exhaust air, and absorbed and muffled by a sound absorbing mechanism formed by combining a sound absorbing material 11 for consisting an air course wall and a back air layer 13. In such a case, air course length extending from the blower motor 2 to the exhaust port 17 of the air course 10 can be lengthened enough since the air course 10 is constituted of a spiral shape, therefore, a muffling effect can be enhanced remarkably. Also, since the air course 10 consists of a spiral shape, noise of the blower motor 2 being a noise source placed in about its center part is not radiated directly into the open air but is subjected to sound insulation enough by plural layers of the air course wall consisting of the muffling material 11. Also, since a space in the periphery of the driving source can be utilized effectively, a space of the whole device can be made small.

Title: Control method of stepping motor
Inventor: BANDAI KOICHI
IPC: F02D41/20
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To make the shaft of a stepping motor stop at the position of a mechanical stopper accurately by a method wherein first driving signals are supplied to turn the shaft until the turn is suppressed by a turn suppressing means and second driving signals are supplied after the supply of the first signal is finished. SOLUTION: If two-phase excitation signals are supplied to a stepping motor 1, its shaft 1a is turned counter-clockwise and a stopper 1b is pressed against a part of a mechanical stopper 5. Even after that, the supply of the two-phase excitation signals are continued until the signals equivalent to 240 steps are supplied but the shaft 1a is stopped at a position of a azimuth 0 deg.. If the supply of the two-phase excitation signals equivalent to 240 steps is finished, the supply of the two-phase excitation signals is once discontinued. At that time, the shaft 1a of the stepping motor 1 is turned clockwise by a bouncing phenomenon but the turning back rate is equivalent to three steps in the case of a two-phase 50-tooth motor. Then, if the two-phase excitation signals equivalent to three steps are supplied, the shaft 1a is stopped at the position of the azimuth 0 deg..  As a result, the shaft is stopped accurately at the position of a turn suppressing means.

IPC: F04B49/02
Filed: 1985-09-27
Abstract: PURPOSE:To enable a low pressure oil path to hold its internal pressure to a level, in which a piston of a high pressure pump can perform return action when an unloader valve is actuated, by providing a throttle member in a relief oil path through which a relief oil inlet of the unloader valve communicates with the low pressure oil path of a low pressure pump. CONSTITUTION:If an operating pressure reaches a specified level or more, high pressure oil in a pilot pressure inlet 25 of an unloader valve 22 overcomes an adjusting spring 35 pressing a spool 24 to be moved while causing it to press a ball member 33, and the unloader valve 22 is actuated by separating a valve seat part 32 from the ball member 33. Consequently, low pressure oil in a low pressure oil path 12 of a low pressure pump 2 escapes to a tank or the like through a relied oil path 27 via a relief oil inlet 26. Accordingly, the low pressure pump 2 can save its driving power, while the escaping low pressure oil in this time is escaped while being throttled by a throttle member 28 provided in the before said relief oil path 27, as a result, the pressure in the low pressure oil path 12 can be held to at least a level, in which a piston 11 of a high pressure pump 1 can perform return action, and the above described piston 11 can be stably further surely slided.

Abstract: PURPOSE:To display a picture of an object while catching it in the center of a screen at all times by generating a video signal resulting from tracing automatically a moving part of a television signal. CONSTITUTION:A television signal and another television signal sent succeedingly are compared by a color element comparator circuit 14, from which difference information is generated and 1st position information of a part having a change on a television screen is generated based on a time difference between the time when the difference information is detected and the time of a synchronizing signal of a relevant television signal. Then 2nd position information 16 to segment a new magnified television picture from an original television signal is generated based on the 1st position information and specific horizontal scanning line information is extracted by the 2nd position information. As soon as the horizontal scanning line information is generated, scanning line information for a prescribed period is extracted from one horizontal scanning line information and the information is used to expand the time with respect to one horizontal scanning line information of a prescribed form of the television signal.
