Title: Circuit for detecting variation of clock pulse width
Inventor: SUGA KIYOSHI
IPC: H03K5/153
Filed: 1988-09-12
Abstract: PURPOSE:To highly accurately detect the variation variation in period of clock pulses by causing an integrator to make integrating operations in the opposite direction during a high-level period to the direction during a low-level period. CONSTITUTION:When a clock input 4 is inputted to an integrator 1, the integrator 1 is reset at the rising timing of the input 4 and, if the voltage of a reference voltage generation circuit 10 is V/2, the output voltage 5 of the integrator 1 also becomes V/2. The integrator 1 integrates inputted pulse signals over one period and a comparator 2 receives an enable signal 8 from a control signal generation circuit 3 at the moment when the integration of one period is completed and can output a clock pulse width variation detecting signal 6 by detecting presence of period variation between a high-level period and low-level period by comparing the voltage 5 with a reference voltage 10. Since the variation of the circuit constant of the integrator 1 can be canceled by the integration of one period, no influence is given to the integrating results of the integrator 1.

Title: Molding of fiber reinforced plastic
Inventor: YOKOYAMA TAKEYOSHI
IPC: B29K105/06
Filed: 1986-09-25
Abstract: PURPOSE:To mold a complicated structural body with a specified thickness, by holding a plastic resin added to a reinforcing fiber between an inner mold and an outer mold having different linear expansion coefficient each other, and pressing it under heating. CONSTITUTION:A prepreg material 12 wherein a plastic resin is added to a tape base material and it is semi-cured is wound in a plurality of layers with a specified thickness on the outer circumferencial surface of an inner mold 10. An outer mold 13 is placed outside them and the prepreg material 12 is thereby held between both molds. When the prepreg material 12 is heated in an over, since the inner mold 10 has larger linear expansion coefficient than that of the outer mold 13, the inner mold 10 makes larger expansion to expand outside. In this case, on both ends of the inner mold 10 in its axial direction, fixing devices 14 having the same linear expansion coefficient as that of the outer mold 13 are set. The inner mold 10 thereby expands toward the outer mold 13 while the expansion of the inner mold 10 in the axial direction is being restricted. The plastic resin thereby receives a uniform compressing pressure from the inside to the outside like this, and at the same time is heated, treated and cured to make it possible to carry out a uniform press-molding on a complicated structural body.

IPC: G06F3/12
Filed: 1982-12-27
Abstract: PURPOSE:To eliminate the thick straight line when a diagram is plotted with straight line by using a frame buffer memory exclusive for hard copy device to store only the information needed for the hard copy. CONSTITUTION:When a line is smoothed, the writing address delivered to a line 12 is coupled with the preceding address. This address is decided by the smoothing process of a vector generator 2. In this case, no writing pulse is applied to a frame buffer memory 11 for hard copy from the generator 2 via a line 17 and the original display position of the straight line is not shown. Therefore no data is written, and only the information needed for hard copy is held by the memory 11. This information is read out for hard copy. In such a way, a copy output which does not thicken the straight lines is obtained when a diagram is plotted by a hard copy device with the straight line.

Title: Semiconductor device manufacturing method and apparatus therefor

IPC: H01L21/302
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To obtain a method and apparatus for manufacturing a semiconductor device, which can measure the amount of deposition on a film in a processing chamber from the outside of the chamber while not hindering the vacuum condition of the chamber. SOLUTION: It is difficult to completely remove a deposited substance 116 even after a cleaning process, and thus a certain constant amount of deposition is accumulated on a quartz cylinder 107 or the like. The deposition film, when deposited on the surface of the cylinder 107, causes the cylinder 107 to be shrunk, generating a thin film stress and deforming the cylinder 107. The amount of such deformation is measured with a displacement measuring device 114 from the outside of a processing chamber. The displacement measuring device 114 uses an element for measuring a distance with a reflecting surface. The displacement measuring device 114 detects reference light 112 from the cylinder 107 to measure a change in the distance until the cylinder 107 with a high resolution.  As a result, there can be realized a semiconductor device manufacturing method and apparatus in which the amount of deposition on a film in the processing chamber and the condition thereof can be measured from outside of the chamber while not hindering the vacuum condition of the chamber.
