Patent JP-H0746125-A (JP)
Title: Pll circuit
Inventor: JOKURA ATSUSHI
IPC: H03K5/153
Filed: 1993-07-28
Abstract: PURPOSE:To improve S/N of the PLL circuit in the frequency synthesizer of a reception system by providing a dead zone for phase comparison and realizing stable synchronous convergence. CONSTITUTION:A phase leading PD pulse is delayed by a delay device 11b and is inputted to the clock input of a D-FF 13b. The PD pulse is integrated by a time constant circuit 10b, and this integral waveform is compared with the threshold of a transistor TR 15b, and, a pulse is generated when it is larger than this threshold. This pulse is inputted to the data input of the D-FF 13b to latch the PD pulse, and the D-FF 13b is reset by an OR gate 14b at the time of disappearance of the PD pulse. Its Q output RD is supplied to a charge pump and a loop filter to obtain the control voltage of a VCO. Consequently, the dead zone is determined by CR of the time constant circuit 10b and the threshold of the TR 15b, and the PD pulse larger than the dead zone is outputted as it is, and therefore, synchronous convergence is stabilized.

Abstract: PURPOSE: To make the noise level freely changeable by adjusting the current flowing between the power source and the internal circuit of the sense amplifier or the like through a current adjustment circuit based on selection signals. CONSTITUTION: Selection signals S are generated by the selection signal generation circuit 10 to cause one of the transistors which are different in size and parallelly connected between the sense amplifier and the power source V to selectively turn the output terminal of the current adjusting circuit 8 on. Then the corresponding current I flows between the power source V and the internal circuit 9 of the sense amplifier or the like. The constitution that this current I is adjustable makes the noise level freely changeable and allows a semiconductor device simplified in design.

Title: Welding torch
Inventor: TAISAKU TAKESHI
IPC: B23K9/12
Filed: 1984-10-02
Abstract: PURPOSE:To improve remarkably the feeding property of a welding wire and the durability of a welding torch by using a wire guide coated with an insulating material such as fluororesin, for a wire feed path. CONSTITUTION:A wire guide 4 is coated with an insulating material of fluororesin. This insulating material abounds in a lubricating property, therefore, a welding wire 11 is scarcely scraped, and even if it has been scraped, since an electric conduction path is not formed in the wire guide, a chip of the welding wire 11 does not adhere to the wire guide 4, and it is discharged suitably together with a gas flow, therefore, the durability becomes excellent remarkably.

Title: Semiconductor memory device
Inventor: SUZUKI TAKAFUMI
IPC: G06F12/06
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To improve the operation speed of a semiconductor memory device provided with two or more memory blocks. SOLUTION: In this device, block selection circuits 51 to 54 and a block decoder circuit 41 are added. Since a memory block enable signal is directly inputted to each memory block 18 to 21, each block 18 to 21 starts an operation at the same time with when a signal becomes enable. The blocks 18 to 21 are decoded in parallel with the decoding of address in each block 18 to 21, and when a memory block to be selected is determined, the selection circuits externally output data of the selected memory block. As for write, the circuit 41 is separately provided and a memory block that should simultaneously select decoding of address in each block 18 to 21 is decoded. When a memory block is determined, only the selected memory block is actually performed writing since a write signal is sent only to the block.

Abstract: PURPOSE:To easily correct a program by providing a recovery time control circuit in a microcomputer. CONSTITUTION:A central control unit 13 activates a chip selection signal CS1 via an internal address bus 16 and a decoder 19 to select an input/output device 141 requiring the recovery time. Then the unit 13 sends a read signal RD when data are read via an internal data bus 15. However, the recovery time is not enough just with transmission of the signal RD in case data are continuously read. Then malfunction may sometimes occur. In this respect, a recovery time control circuit 11 is used to secure the timing of the signal RD. Thus the satisfactory recovery time is secured for the signal RD.
