Patent JP-H02188027-A (JP)
Title: Frequency synthesizer
Inventor: HARUYAMA NOBUO
IPC: H03L7/22
Filed: 1989-01-13
Abstract: PURPOSE:To shorten muting time by setting a limit value which is smaller than the minimum value of the frequency variation width of a voltage-controlled oscillator constituting a 2nd PLL and supplying a signal of reference frequency to 1st and 2nd PLLs so that the limit value is not exceeded. CONSTITUTION:When a channel to be received is selected by a pushbutton type channel selecting means 9, a binary code signal corresponding to the frequency of the channel is supplied to a calculating circuit 10. This calculating circuit 10 finds frequency division ratios N1, N10, and N2, and N20 for generating a local oscillation signal by the frequency synthesizer. The frequency division ratios N1, N10, N2, and N20 are supplied to a decision circuit 12 and compares with a frequency division ratio corresponding to a preset limit value Li. Then only the frequency division ratios N1 and N2 which do not exceed the frequency division ratio are supplied to the frequency synthesizer 11. Therefore, while high resolution is maintained, the variation width of the frequency of the voltage-controlled oscillator can be reduced.

Abstract: PURPOSE:To provide a printed wiring board which can constitute a mounting- circuit device or the like whose reliability is high. CONSTITUTION:The title board is a printed wiring board which is provided with a through hole 2 used to connect required circuit-pattern layers electrically. It is constituted in such a way that said through hole 2 is filled with a conductive metal 4a (4b) and that at least one edge is covered with a masking layer 5 which can be stripped or melted and removed. Since the through hole 2 connecting the circuit-pattern layers electrically is filled with the conductive metal 4a (4b) and at least one edge is covered with the masking layer 5 which can be stripped or melted and removed, it is possible to wholly restrain or prevent that the conductive metal 4a (4b) filled into the through hole is melted and flows out to the outside of the through hole 2 even when the soldering process of a mounted electronic component is performed at a high temperature. Consequently, it is possible to prevent that the conductive metal 4a (4b) filled into the through hole 2 is melted and flows out, and a required electrical connection function is always kept and displayed.

Title: Damage preventing method by erroneous connection of external unit in computer system
Inventor: KAWAGUCHI TAKESHI
IPC: G06F11/00
Filed: 1990-01-17
Abstract: PURPOSE:To prevent the damage of external units owing to errorneous connection by turning on the external power supply switches of the external units only when respective external units recognize that they are appropriately connected to prescribed slots. CONSTITUTION:When internal power is supplied by the turning-on of a start switch 7, CPU 1 checks whether the prescribed external units 4 and 5 are sequentially and appropriately connected to all the slots or not. When they are recognized to be appropriately connected to all the slots, a power supply command is given to an external unit 6. Thus, the external unit 6 conducts external power supply switches sw1 and sw2 inserted into the power circuits of the external units 4 and 5. Thus, the external units 4 and 5 are prevented from being damaged by extraordinarily high external power owing to errorneous connection.

Title: Control method for electric power steering device
Inventor: NISHIMORI TAKESHI
IPC: B62D119/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent steep change in the steering torque in the event of failure in an abnormal vehicle behavior sensing means in an arrangement where a control to suppress abnormal behavior is conducted by an electric power steering device. SOLUTION: When abnormality in vehicle behavior is sensed by a vehicle behavior sensing means to sense the behavior of a vehicle, a steering reaction force is generated so as to suppress the abnormality in behavior by a motor which is to generate an assist force for driving the steering vehicle wheel in compliance with the turning angle of a steering wheel. In this electric power steering device, the steering reaction force is decreased gradually in case any failure in the vehicle behavior sensing means is detected. This leaves the component of assist force to allow suppressing a steep change in the steering torque, and it is possible to suppress change in the feeling in the steering operation before and after occurrence of failure as much as practicable.
