Title: Liquid delivery apparatus of high-speed liquid chromatograph
Inventor: NAKAMOTO AKIRA
IPC: F04B49/06
Filed: 1982-02-27
Abstract: PURPOSE:To correct automatically compressibility for various solvents and to prevent  pulsation of a delivery liquid at a high pressure time, by comparing the pressure of a  supplying solvent with the set pressure and controlling a discharge moving volocity of  a plunger under prescribed conditions. CONSTITUTION:A solvent sucked in a pump room 12 through an entrance check valve  14 by moving a plunger 9 linearly with a deformed cam 19 detecting a position by a  photocoupler 20 is supplied to a solvent supplying passage 8 passing through an exit  check valve. On this occasion, the pressure of the feeding solvent is measured and  stored via a pressure sensor 4 by a switch turning off instantaneously at the time of  arriving the plunger 9 at a prescribed position. The plunger 9 is moved quickly during  pulse time of width corresponding to this stored pressure and solvent compression at  discharge starting time is carried out smoothly. Moreover, the plunger 9 is moved in  high speed so that the difference between the stored pressure set as the set pressure  and the measured pressure of the sensor 4 is adjusted to a prescribed value and the discharge quantity is controlled. Further, the correction of compressibility of the solvent  having different compressibility is carried out and pulsation of the solvent at feeding time under high pressure is prevented.

IPC: B29C59/04
Filed: 1987-02-13
Abstract: PURPOSE:To facilitate processing of a recessed pattern on the surface of a plate elementary material, by a method wherein a processing jig is interposed between an upper suction member or a lower suction member and a plate elementary material, the processing jig is shifted simultaneously with the plate elementary material in the same direction as a feeding direction of the plate elementary material, and simultaneously with suction and cooling of the plate elementary material, a pattern of a processing jig is patterned on the surface of the plate elementary material. CONSTITUTION:When a plate elementary material 4 is guided into a molding tool 1, a processing jig 5 begins running within the molding tool 1 through a rotary driving of a driving roller 6, and the plate elementary material 4 and processing jig 5 pass through the inside of the molding tool 1 in a body. In this instance, suction force of an upper section member 2 is transmitted to the plate elementary material 4 through a space between wire rods 5a of the processing jig 5. Therefore, the top of the plate elementary material 4 is sucked reliably by the upper section member 2, the processing jig 5 is intruded into the top of the plate elementary material 4 through this suction force, a checkered recessed pattern through the processing jig 5 is patterned on the top of the plate elementary material 4, and cooled at the same time. As it is unnecessary to apply perpendicular lower face to the top of the plate elementary material 4, it does not happen that the top of the hollow plate elementary material 4 may deform through recession of the same.

Abstract: PURPOSE:To automatically benefit the effect of diversity without performing the comparison and the switching of reception, by detecting the delay of a signal obtained by switching the signal from a diversity reception antenna by every 1/2 of a time slot, and extracting an original digital signal. CONSTITUTION:By switching the signal from each of antennas 1-1 and 1-2 by every 1/2 of the time slot synchronizing with the width of the time slots #1, #2... of the digital signal, and deriving it to a reception circuit 3, signals SA and SB from first and second antennas are supplied alternately to the reception circuit 3.

Abstract: PURPOSE:To provide a method and device for polishing chamfered parts of wafers by which the polishing time can be reduced and the productivity can be improved. CONSTITUTION:The chamfered part of a wafer W on the outer peripheral surface of the wafer W is polished by pressing the chamfered part against the polishing grooves of cylindrical buff 40 carrying the polishing grooves over the entire circumference on its inner peripheral surface while the buff 40 is rotated. A polishing device 1 is provided with the buff 40, a buff driving means which rotates the buff 40, and a wafer driving means 30 which presses the chamfered part of the wafer W against the polishing groove of the buff 40 while holding and rotating the wafer W. When such a method and device are used, the contact width of the wafer W can be increased as compared with the conventional polishing method in which the chamfered part is pressed against the external surface of the buff 40, because the chamfered part of the wafer W is polished while the chamfered part is pressed against the internal surface of the cylindrical buff 40. In addition, the polishing time can be reduced and the productivity can be improved, because the orientation flat W2 can be polished in parallel with the chamfered part by means of the outer peripheral surface of the buff 40.
