Title: Suction port of vacuum cleaner and vacuum cleaner having the same
Inventor: YAMAGUCHI ATSUSHI
IPC: A47L9/02
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To improve operability when a suction port main body is moved in the lateral direction by arranging a wheel which projects downward from the suction port main body by a movement of a connecting tube and rotates in the direction different from the advancing direction of the suction port main body, under the suction port main body. SOLUTION: In a lower case in a suction port main body, a pair of wheel stands 120 where a lateral directionally moving wheel 123 is journalled at an almost right angle to a roller 132, are journalled to both sides of a casing so as to be capable of protruding/retreating. These wheel stands 120 are energized upward by a spring 175, and when the casing rotates upward around a horizontal rotary shaft by a wheel protruding/retreating projection 176 arranged in the casing, the wheel stands 120 are pushed, and project to a lower case under surface, and when the casing rotates up to the uppermost part, the roller 132 is constituted so as to float from a floor surface. Therefore, the lateral directionally moving wheel 123 journalled at an almost right angle to the roller 132 is grounded, and excellent traveling performance when moved in the lateral direction, can be secured.

It is desirable to use a polyester whose transparency is not lowered and dimensions are not changed when heated, since the film is put in a heated condition at the time of manufacturing liquid crystal panels. It is desirable from the point of practical use that the coefficient of contraction is <=5% when held in a 150 deg.C atmosphere for 30min and the haze is <=5% at a thickness of 100mum. These conditions are achieved when a film of >=30X10<-3> in the degree of surface orientation is heat treated so that its mean refractive index becomes >=1.595 in the manufacturing process of the film.

Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To shorten the settling speed of the rotational speed of a disk with a simple constitution by quickly shifting the rotational speed of a disk to the direction of a target speed. SOLUTION: When the rotational speed of a disk 11 approaches a target speed and a synchronous OK signal is generated from a synchronization separating circuit 18, a frequency comparing circuit 22 compares the frequency of the synchronous OK signal with the frequency of a reference signal. Thereafter, when the frequency of the synchronous OK signal becomes higher than the frequency of the reference signal and the polarity signal meaning the result is outputted from comparing circuit 22, a control circuit 29 generates a changeover signal for controlling a changeover switch 28 so that the addition signal of an adding circuit 24 is guided to a power amplifier circuit 25 to control the rotational speed of the disk 11 to the target speed.  Moreover, when the rotational speed of the disk 11 is wanted to be quickly lowered, the rotational speed of the disk 11 is made to be reduced based on at first a negative maximum accelerating signal from a negative maximum acceleration circuit 27.

Title: Structure of steam discharge pipe
Inventor: YAMANARI SHIYOUZOU
IPC: F28B3/06
Filed: 1981-12-16
Abstract: PURPOSE:To make it possible to reduce a pressure load taking place due to pulsating  air bubles generating at the time of releasing steam by a method wherein in the structure of the steam discharge pipe for releasing the steam directly from a high pressure  steam condensing water pool from a high pressure steam system, a steam releasing  outlet port is provided in the water pool so as to face upward. CONSTITUTION:A steam discharge pipe 26 is provided so as to extend into the pool  water 30 within a pressure control pool 32 via a vent pipe 29 and the extended end of  the pipe 26 is made to open upward at a T-quencher section 27. When the discharging  of the steam is started, the air bubbles 31 generating in the pool water 30 due to the  steam release from the pipe 20 moves to the upper part of the pool water 30 and  reaches the surface of the water quickly due to buoyancy and a water current. Accordingly, the duration of the pulsation of the air bubbles 31 is shortened sharply so  that the pulsating pressure load applied on the wall of the pressure control pool 32 is  reduced to about two-thirds of the like load taking place in the case of the conventional steam discharge pipe. Further, the pool water 30 heated by the high temperatur  steam is agitated by the steam discharge pressure and the convection due to the difference in temperature between the water and the steam so that the local elevation of  the temperature of the pool water 30 is prevented.
