IPC: B66C23/66
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To improve suspending performance without increasing weight of a boom more than necessary by making boom compressive force uniformly act on respective members. SOLUTION: A top link 8 is arranged on the front side of a boom top section 23a, and a pendant link 9 is arranged on the rear side of the boom top section 23a. A second pendant link 24 projecting backward more than the pendant link 9 is also fixedly arranged, and a pendant 12 is locked on this, and a locking point of the pendant 12 is arranged backward.

Filed: 1991-08-08
Abstract: PURPOSE:To develop ion plating device having the excellent efficiency of utilizing electrons by providing a reflection plate for the electrons from a plasma generator in a vapor deposition chamber of the ion plating device. CONSTITUTION:The inside of a plasma forming device 9 and the vacuum vapor deposition chamber 1 connected thereto is evacuated to a vacuum and gaseous Ar is gradually supplied from a gas supplying pipe 15 of a plasma forming device, simultaneously with which the electrons are released by energizing a hot cathode 10. A voltage is then impressed between the hot cathode 10 and a discharge electrode 12 to generate a discharge. Ar molecules are ionized by the electrons from the hot cathode 10 to generate plasma P. The electrons formed therein advance rectilinearly in the vapor deposition chamber 1. On the other hand, a raw material 3 for vapor deposition in a crucible 2 is heated and evaporated by the electrons from a filament 4 and collide against the electrons from the plasma forming device 9, by that, the raw material is ionized and a vapor deposited film is formed on a substrate 6. The electrons are partly not utilized and advance rectilinearely and, therefore, these electrons are reflected by the reflection electrode 21 to irradiate and evaporate the raw material 3 for vapor deposition in the crusible 2. The electrons are thus effectively utilized for the vapor deposition effect.

Abstract: PROBLEM TO BE SOLVED: To prevent a flame from entering the elevator shaft side in a fire of the landing side by arranging a fire resisting cover in the adjacent to a door stop part in the elevator shaft side of a drawn door which opens/closes the doorway of the landing, interlocking the cover with the car, and when the drawn door is closed, shifting it to a position for blocking the door stop part of the landing. SOLUTION: One end of a link 12C is pivoted 13F on an engagement cam 7A and the other end is pivoted 13E on one end of a link 13B. The other end of the link 13B is pivoted 13C on a fire resisting cover 11 and pivotally supports 13D the intermediate part of the link 13B to a door 3A. At the same time, a link 12A is attached to the lower part of the fire resisting cover 11 and moves the resisting cover 11 to a position for blocking the door stop part, when the door 3A is closed. If a fire breaks out on the landing side, the door stop rubber is melted, consequently the door is deformed to the elevator shaft side, and a clearance of the door stop part is expanded, this constitution shuts the elevator shaft side from the fire by the fire resisting cover 11 in the closed states of the doors 3A, 3B and prevents a flame from blowing out to the elevator shaft side.

IPC: B01F5/04
Filed: 1992-07-27
Abstract: PURPOSE: To dissolve a gas in a flowing liq. by providing a circulating side flow for circulating and dissolving bubbles therein alongside a main flow region and producing a concn. gradient driving the gas from the circulating side flow region to the main flow region. CONSTITUTION: A liq. flow 14 is made to flow in an insert 42 from a first section 54 and a second section 56 to side pocket regions 62 and 64 and separated into a main flow region 66 and an opposed side flow regions 68. Since the bubbles 28 are circulated in the circulating side flow regions 68 and dissolved, the amt. of dissolved gas is increased. When the amt. of dissolved gas increases in the side flow regions 68, the dissolved gas is returned to the main flow region 66. Consequently, a concn. gradient is produced between the side flow regions 68 and the main flow region 66. Accordingly, the gas to be dissolved is constantly sent to the side flow regions 68 and continuously dissolved in the side flow regions 68.

The distortion of the waveforms of the signals obtd. in such a manner is decreased and the high C/N is obtd. at the time of reproduction. The recording with the high C/N by the bubble mode is possible in this way.
