Title: Phase lock loop circuit
Inventor: NISHIMURA EIZOU
IPC: H03L7/08
Filed: 1999-03-30
Granted: 2003-06-21
Abstract: The present invention is related to PLL (phase lock loop) circuit, which has phase comparator 20, complete integration loop filter 21, VCO14, and loop counter 22, and is provided with a prediction window circuit 23 that outputs an HWIN (prediction window signal) for predicting the generation position of an REF and an absence compensating circuit 24, which outputs a d.REFX (the first correction signal) for correcting the absence and a d.VARX (the second correction signal) for canceling the phase difference between a VAR (comparison signal) and the d.REFX. The phase comparator 20 outputs signals Ph1 and Ph2 corresponding to the phase difference between the VAR and d.REFX and signals Ph1 and Ph2, which correspond to the phase difference between the d.REFX and d.VARX when REF is absent. By performing proper absence compensation when an REF is absent, a stable CLK (clock) is generated even VCO 14 (voltage-controlled oscillator), which has a very wide frequency variation range, is used. In addition, gate control signal Gc, which generates and makes the phase of VAR exceed one clock, is disposed. A triple-state buffer, which outputs triple-state signal based on the phase difference of REF and VAR, and is controlled to stay at an activated state according to the signal Gc, is disposed at the phase comparator. Under the condition that phase difference of REF and VAR is in the vicinity of zero, a stable clock is generated as VCO 14 having a very wide frequency variation range is used.

Title: Injection molding machine
Inventor: EMOTO ATSUSHI
IPC: B29C45/76
Filed: 1999-04-30
Granted: 2002-03-11
Abstract: This invention provides an injection molding machine whose object is to increase the mechanical efficiency of an injection molding machine, decrease the inertia, and decrease the axial length. The injection molding machine comprises a cylinder member; an injection member disposed within the cylinder member such that the injection member can advance and retract; an injection motor 82; and a transmission shaft which is connected to the injection member such that the transmission shaft can rotate relative to the injection member. The transmission shaft has a rotation transmission portion, to which rotation of the injection motor 82 is transmitted, as well as a motion conversion portion for converting rotational motion to linear motion. The injection motor 82 and the transmission shaft are disposed on the same axis, and the transmission shaft is advanced and retracted inside the rotor 92 of the injection motor 82. In this case, since rotation of the injection motor 82 is transmitted directly to the transmission shaft without intervention of a speed reduction mechanism, a pulley, and the like, mechanical efficiency can be improved, and inertia can be decreased. Further, the time required for changeover from the injection stage to the pressure holding stage is shortened. Since the transmission shaft is advanced and retracted inside the rotor 92 of the injection motor 82, the injection molding machine can be reduced in axial length.

Title: Method of forming metal oxide semiconductor field effect transistor
Inventor: LIN JIAN-TING
IPC: H01L29/772
Filed: 1999-10-11
Granted: 2001-04-01
Abstract: This invention is about method of forming metal oxide semiconductor field effect transistor, in which the metal oxide semiconductor field effect transistor is formed by a specific procedure so as to effectively control thermal damage during the fabrication process. This invention at least includes the following procedures. At first, a substrate is provided, on which the isolation and well regions are formed. The first dielectric layer, conduction layer and antireflection layer are sequentially formed on the substrate. The photolithography and etching process are used to form a gate. After forming the source, drain and spacer, thermal process is performed onto source and drain such that the first metal silicide is formed on source and drain. The second dielectric layer is used to cover substrate and gate. The surface of the second dielectric layer is planarized such that the antireflection layer of gate is completely stripped and the conduction layer of gate is partly stripped off. After forming the second metal silicide on the conduction layer, the spacer is removed and, the lining pad and doped source/drain are formed. Finally, the third dielectric layer is formed on the second dielectric layer to cover gate. Apparently, the great characteristic of this invention is that the doped source/drain and lining pad are formed after a series of thermal process have been performed. Therefore, the influence of thermal process on doped source/drain and lining pad, such as deposition and so on, can be effectively avoided.
