Title: Method for controlling difference between left and right rotation of side gear of working machine
Inventor: YOSHIDA SUSUMU
IPC: F16H48/30
Filed: 1988-02-17
Abstract: PURPOSE:To prevent only one wheel from rotation and stop by setting a necessary rotational difference between left and right wheels with a transmission to carry out a controlling action when energy acts which is going to exceed the set rotational difference. CONSTITUTION:The rotational frequency of a pinion gear shaft 3 is controlled by the rotational frequency of a working machine to control the rotational difference between left and right side gears 2. If the rotational frequency of the working machine is equalized to that of gear in the same row as the side gear 2 for converting 90 deg. the rotation of the pinion gear shaft 3, the rotation of the pinion gear 3 is controlled to zero without generating the rotational difference between the left and right side gears 2. Thus, by incorporating a transmission between the rotating working machine and the 90 deg. converting gear in the same row as the side gear can be obtained a necessary control valve of the rotational frequency of the pinion shaft 3.

Title: Testing mechanism for library device
Inventor: KASAI KAZUNORI
IPC: G11B19/02
Filed: 1995-02-23
Abstract: PURPOSE: To simplify a test operation and to improve the efficiency of the testing by automatically retrieving the condition of a library device, making a first empty storage element as a carrier element and conducting the test by internally storing. CONSTITUTION: In a started test program, a command is issued to grasp the situation within the library device and a storage element 11 is checked to find out whether the element is occupied by a medium or not. Then, the test program captures the element 11 as two drive carrier elements. By this operation, carrier elements (storage elements '01' and '02') are converted into empty storage elements '03' and '04' 11. If the element 11 is continuous, the element 11 having continuous element addresses is captured. Note, however, that these are not necessarily continuous and may be skipping here and there.

Title: Volute tail of fluid machinery
Inventor: TAGAWA MASASHI
IPC: F04D29/44
Filed: 1995-02-23
Abstract: PURPOSE: To restrain an increase in the fluid pressure fluctuation caused by mismatching of flow even in the case of a partial flow by providing plural through holes inclined in such a manner that the surface side of the volute tail is communicated with the back side and an opening of the back side is positioned in the rear of an opening of the surface side along the flow. CONSTITUTION: A communicating hole 5 is inclined in the flow direction from the surface 3 of a volute tail 2 to the back 4, thereby correcting nonuniformity of a flow field between the tail surface 3 and the back 4 caused by angle mismatching during low-flow operation and relaxing the fluctuation of a pressure field. Some of a liquid is forced to flow from the tail surface 3 to the tail back 4 by the communicating hole 5, so that a separating part produced in the tail back 4 is blown off to reduce a pressure difference between the tail surface 3 and the tail back 4. Thus, the pressure fluctuation which the blade tip of the rotating impeller undergoes when it passes through the tail part is lightened because the static pressure field itself is made uniform, and even in the case of partial flow operation with a low flow, stable pump operation can be performed.

Filed: 1984-02-28
Abstract: PURPOSE:To manufacture an inexpensive adsorbent having excellent adsorption performance at even high temp. by arranging a carbon element-contg. solid under high temp. atmosphere to bring the solid into contact with sulfur or a sulfur compound and forming the sulfur compound on the surface of said solid mainly. CONSTITUTION:A carbon element-contg. solid is arranged under high temp. atmosphere of about 600-900 deg.C and brought into contact with sulfur or a sulfur compound to form the sulfur compound on the surface of said solid mainly. A place where the contact of said solid 13 and sulfur or the sulfur compound is performed is regulated to, for example, the inside of an SO2 reduction tower 3 of a stack gas desulfurization apparatus A. As a result, an inexpensive adsorbent having excellent adsorption performance at even high temp. can be manufactured. A conventional S-contg. activated carbon can be used at only the temp. range of about <=120 deg.C, but said adsorbent can adsorb heavy metals at even high temp. However, the adsorbent is preferably used at <=350 deg.C under existence of oxygen to prevent it from burning and furthermore the usage at <=600 deg.C is necessary under coexistence of moisture.
