Title: 3"-acylleuomycin a13
Inventor: SAKAKIBARA HIDEO
IPC: A61P31/04
Filed: 1979-08-24
Abstract: NEW MATERIAL:A 3"-acylleucomycin A 13  of formula I (R is acetyl or propionyl group), and a salt thereof.  
     EXAMPLE: 3"-Acetylleucomycin A 13 .  
     USE: An antimicrobial agent having a more powerful antimirobial activity than leucomycin A 13 , effective against microorganisms resistant to other macrolide antibiotics and mycoplasma, and usable as a syrup for a child due to little bitterness.  
     PROCESS: A compound of formula II (R 1  is lower alkanoyl) is reacted with a chloroacetyl halide to protect the OH groups at the 3-and the 9-positions. The reaction product is then acylated with an acetyl halide or propionyl halide at the 3"-position to give a compound of formula III (R 2  is chlorinated acetyl), which is then treated with ammonia in methanol to remove the protecting groups. The resultant compound is then heat-treated to eliminate the acyl group at the 2'-position and afford the compound of formula I.

Title: Semiconductor manufacturing device
Inventor: NINOMIYA TAKAFUMI
IPC: B24B27/00
Filed: 1988-04-30
Abstract: PURPOSE:To set up the floating up amount of a processing head easily and accurately after replacing the processing head subject to dispersion in dimension for enabling the floating up amount to be equalized without depending upon the skill level of operators for removal of a wafer bump by a method wherein the correlation of the floating up amount of a processing head to the lowering down amount of an arm is calculated to set up the floating up amount of the processing head based on the calculated corelation. CONSTITUTION:Assuming the height position of an arm 3 wherein the lower surface of a processing head 4 with gas discharge stopped abuts against a reference surface as a reference position, the correlation of the floating up amount from the reference surface of the processing head 4 to the lowering down amount of the arm 3 is calculated by floating up the processing head 4 at specified gas discharging pressure and lowering down the arm 3. The floating up amount of the processing head 4 from the height position up to a semiconductor wafer 2 is set up based on the calculated corelation. Through these procedures, the floating up amount of the processing head 4 can be set up easily and accurately so that the trouble of disparsion in the height after processing a bump 2a due to the difference in the skill level of operators may be avoided.

Title: Manufacture of semiconductor pressure sensor
Inventor: SUGIMOTO MASAHIRO
IPC: H01L29/84
Filed: 1991-04-12
Abstract: PURPOSE:To prevent the deterioration of the strength of a diaphragm at the time of forming a cavity constituting the pressure reference chamber of a semiconductor pressure sensor. CONSTITUTION:A semiconductor substrate 50 provided with an etchant inlet passing through a diaphragm formed on one principal plane is accommodated in an etching tank 20 formed when a freely opened and closed cover body 22 is airtightly mounted on a container 21 for accommodating an etchant A. A high-pressure gas is introduced through a supply pipe Q1 from a high-pressure gas supply source 30 into the etching tank 20 so that the inside of the etching tank 20 is held at a predetermined high pressure. In this high-pressure state, the etchant is injected via the etchant inlet so that a part of the semiconductor substrate 50 under the diaphragm is removed by etching and a pressure reference chamber composed of a cavity of predetermined shape is formed. Because the volume of a reaction gas generated by etching decreases in inverse proportion to pressure, the number of generated bubbles in the cavity diminishes so that the diaphragm is prevented from deteriorating in strength.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To shorten a time (an initial state friction coefficient rise time) required during a time in which a friction coefficient at the initial stage of use is stabilized. SOLUTION: In a friction material containing a fiber base material, a resin bonding agent consisting of a thermosetting resin, and a filler, polish powder (polish chip produced during polishing finishing) of a rubber mold friction material is mixed as at least a part of the filler in a ratio of 10-70wt.% based on a whole of the friction material. Proper flexibility and wearing property are added to the friction material, and brought into a dense state, whereby high comformability with a mating material is provided and working therewith is practicable and as a result, a working time is remarkably shortened. Further, since polish power being waste is re-utilized, resources are effectively utilized.

Filed: 1995-04-10
Abstract: PURPOSE: To restrain an amount of occurrence of a tip cavitation by chipping both corner parts between a tip and a front edge of each blade of an impeller, and forming a smooth curved surface. CONSTITUTION: A clearance δ set up so as to make the impeller 7 rotates smoothly, and to get a fluid leakage minimized, is formed in an interval between a tip 10 of a blade 10 of impeller 7 and an inner circumferential surface of a wear ring 2. In addition, a square corner part between the tip 10a and a front edge 10b of the blade 10 is chipped, whereby a smooth curved surface 21 consisting of a circular arc of a radius R is formed, by way of example.  A chip cavitation is produced in a clearance δ in the section of the blade 10 being lowest in static pressure, but since the square corner part between the tip 10a and the front edge 10b of the blade 10 is chipped and this curved surface 21 is therefore formed, an inlet of a fluid S to the clearance δ is an inlet sectional position of the actual blade 10, namely, it comes to a Q point (a position where static pressure is boosted as far as the constant value) after shifting to the downstream side from the blade front edge 10b. Accordingly, an amount of occurrence of the tip cavitation is restrained.

Title: Polyphase current collecting device
Inventor: KASAI SHIYOUJI
IPC: B60L5/38
Filed: 1978-09-08
Abstract: PURPOSE: To extend the life of a polyphase current collecting device by mounting slides of the respective current collecting devices on current collecting shoes of insulating material such as reinforced plastic, synthetic resin or the like to thereby improve the follow-up property of the slides with trolley wires.  
     CONSTITUTION: The current collecting shoe 10 mounted with slides 9, 9 is formed of insulating material such as synthetic resin, reinforced plastic or the like to transmit the electric power collected through the slides 9, 9 from trolley wires 4a-4c directly to conductors so as to supply it to the electric equipment of an electric motor behicle. Since this construction reduces the masses of the slides 9, 9 and the current collecting shoe 10 to thereby improve the follow-up property with the trolley wires 4a-4c, it reduces an arc caused by the separation of the shoe 10 from the trolley wires 4a-4c so as to remarkably extend the lives of the slides and the trolley wires. Inasmuch as the collected power is completely insulated from the shoe 10 and not introduced to current collecting arm 11, bracket 12 or the like connected thereto, it can minimize the interval with the adjacent bracket and accordingly the interval with the trolley wires.
