Title: Jitter generation circuit
Inventor: NONOYAMA MIHIRO
IPC: G01R31/00
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To facilitate generation of jitter signal by providing a logical gate receiving the connection signal outputted from each power supply control means being connected in series with the output of a signal delay means receiving a clock signal and a clock frequency division circuit. SOLUTION: Assuming that switches 11, 15 select the output from a first delay signal line and a second frequency division circuit and a following relationship is satisfied; a variable resistor 16 > a variable resistor 17, output from a buffer circuit 8 is delayed by an amount equal to the element lag of the buffer circuit 8 when a clock signal is fed to an input terminal 1. Output from the second frequency division circuit has a waveform subjected to frequency division by a factor of 4. The inclination at the changing point of a connection signal waveform at the output of the variable resistors 16, 17 depends on the resistance thereof. When the logical level of the buffer circuit 8 is set at 1/2VDD, a clock signal having a jitter for the waveform thereof is outputted from an output terminal 7.

Title: Molding die for fiber reinforced plastic product
Inventor: MOMOSE SHINYA
IPC: B29C33/38
Filed: 1986-07-30
Abstract: PURPOSE:To favorably keep the releasing effect of releasing agent over a long term, to improve the corrosion resistance and wear resistance of a mold surface and to contrive to save the weight of a mold by a method wherein a large number of fine cracks, which are produced on the surface of an anodized film formed onto the mold surface consisting of aluminum material, are impregnated with releasing agent. CONSTITUTION:A large number of cracks 11, which are produced on the surface of an anodized film 10 formed onto a mold surface 9 consisting of aluminum alloy, are impregnated with releasing agent. When the mold surface 9 is heated, the anodized film 10 expands and the widths of the cracks 11 widen so as to let the releasing agent on the mold surface 9 to flow into and to store in the cracks. On the other hand, when the mold surface 9 is cooled by being supplied with cooling medium, the anodized film 10 contracts and the widths of the cracks 11 narrow so as to ooze the stored releasing agent on the mold surface 9. Because the releasing agent comes into and goes out of the cracks 11 in response to the change of temperature of the mold surface 9, the releasing effect of the releasing agent can be kept over a long term. In addition, the existence of the anodized film 10 improves the corrosion resistance and wear resistance of the mold surface 9 and the long service life of a mold results.

Title: Exposure device for wafer or photomask
Inventor: SAKADO KEIICHIROU
IPC: G03F1/76
Filed: 1980-12-18
Abstract: PURPOSE:To obtain always correct exposure irrespectively of the light intensities of a light source by correcting the value corresponding to the exposure to be exposed only during the closing operation period of a shutter from the target value corresponding to the correct exposure. CONSTITUTION:A position detector 6 opens a switch 20 when a rotary disc 3 comes to such a position where it transmits the light from a light source fully. The switch 20 opens at the full opening of the shutter, after which it is held open until the end of exposure operation. Hence, a capacitor 21 connected in series to the switch 20 holds the voltage corresponding to the integrated value of the quantity of light. Further, a differential amplifier 22 is inputted with reference voltage Es which is a target value and the voltage Vc of the capacitor 21 and outputs the differential value VR thereof. A comparator 15 compares the integrated voltage Vs of the quantity of light and the voltage VR and when these coincide nearly, its output inverts to reset an FF circuit 16. Since in this way the start of the shutter closing operation is changed according to the integrated value of the quantity of light, always the correct exposure is obtained irrespectively of the light intensities of the light source.

Title: Edger rolling method
Inventor: MIZUTA TOKUO
IPC: B21B1/22
Filed: 1985-08-15
Abstract: PURPOSE:To improve the biting of a rolling material so as to prevent the buckling of the material during rolling and to permit large cross rolling reduction by inclining the upper part of a vertical roll pair in the direction opposite from the progress direction of a rolling material within the vertical plane parallel with the progress direction. CONSTITUTION:The upper part of a pair of the vertical rolls 1 is inclined at a suitable angle theta (about 5 deg.) in the direction opposite from the progress direction of the rolling material S within the plane parallel with the progress direction. The material S tends to curve by receiving rolling down force in the resultant force (f) direction of the rolling force F and the upward component of force fR of frictional force but is restrained by a table roll 2 so that the large cross rolling reduction is made possible without buckling. Since the rolls 1 are inclined by about 5-10 deg. so as to widen the space in the upper part thereof, the rolls start the biting of the top surface of the material S at C' which is below the limiting biting quantity C. The rolling material is thereby satisfactorily bitten. The large cross rolling without buckling is thus made possible.
