Title: Tape transfer machine
Inventor: MASUDA SHUZO
IPC: G11B15/18
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To unnecessitate discrimination of a cassette and detection of the tape remaining amount by detecting only the rotational speed of a supply reel and controlling the speed of a driving means for a take-up reel so that the rotational speed of the supply reel becomes a specified set speed. SOLUTION: When the speed of the supply reel 13 which is detected by a sensor 14, is not more the preset rotational speed, a motor 17 is accelerated by a controller circuit 16. When the speed is faster than the rotational set speed, the motor 17 is decelerated by the controller circuit 16. When it is detected as the rotational set speed, the control is made so as to keep the speed of the motor 17 at that time. When the tape is transported and attained around the tape end while thus keeping the rotational speed of the supply reel 13 to the rotational set speed, the tape speed Vt around the tape end is shown as Vt=D×π×Ws (D is diameter of a hub, Ws is rotational speed of the supply reel), independently of the length and thickness of the tape.

Filed: 1993-12-22
Abstract: PURPOSE:To realize a highly efficient particle image analyzer with a higher sorting accuracy by allowing the setting a criterion for requiring closer sorting or not corresponding to each of facilities in hospitals, for example. CONSTITUTION:A roughly sorting section 291 executes a roughly sorting of particles to supply the particles to a judging section 301 for requiring closer sorting or none. The judging section 301 compares the results of the closer sorting with a criterion value stored in a criterion value memory section 300 to judge normality or abnormality and hence, it is determined whether the closer sorting is necessary or not. The criterion value stored in the memory section 300 is set through an input/output control section 302 from a keyboard 33 and can be altered depending on an object to be inspected. When the judging section 301 determines that the closer sorting is necessary, it directs an image processing control circuit 26 to make a closer sorting processing. A characteristic parameter for the closer sorting is supplied to a closer sorting section 290 by a control command of the control circuit 26 to perform a closer sorting and the results are supplied to the judging section 301. The judging section 301 stores at particle image to an internal image memory 31 according to a command from the keyboard 33 and the results of the sorting are displayed.

Abstract: PURPOSE:To simplify and shorten the manufacturing process, reduce the manufacturing cost and manufacture a long fiber reinforced ceramic by inserting ceramic long fibers between plates of superplastic ceramic, pressure deform the plates at the superplastic developing temperature zone and wrapping the ceramic long fibers into the superplastic ceramic. CONSTITUTION:For example, bonding faces 2a of plates 2 of 2mm thickness of very fine crystal grains of ZrO2 (grain diameter 2mum or less) are plane ground to approximately 3mum surface roughness. For example, SiC fiber 1 is inserted between retaining plates 5 and 6, and the plates 2, 2 are set and pressure deformed in the vertical direction at the superplastic developing temperature zone,which is the temperature of 1000-1650 deg.C, under the vacuumized state, and at the deformation speed of 1X10<-3>S<-1> or less, and a material 10 wrapping in the SiC fiber 1 is manufactured between the integrated plates. When the temperature is less than 1000 deg.C, the plastic deformation resistance of the material is large, while beyond 1650 deg.C, the degree of grain growth of ceramic grains is large to invite the deterioration of a matrix. When the deformation speed faster than above-said is applied, cracks are generated in the material.
