Title: Vacuum cleaner
Inventor: OHARAGI HARUO
IPC: H02P6/06
Filed: 1986-10-08
Abstract: PURPOSE:To allow a brushless DC motor to be kept under an optimum motor control in accordance with a load change of a vacuum cleaner, by a method wherein the motor is subjected to open-loop voltage control based on the speed command and by correcting the speed command in accordance with the load current. CONSTITUTION:When the command is inputted into a microcomputer 13 from a speed command circuit 18, the microcomputer outputs the voltage command. This voltage command is inputted into a voltage command circuit 21 and gives its output to a base driver 19. A brushless DC motor is hence operated in open- loop voltage control based on the speed command. Further, by inputting the output of a current detection circuit 17 into the microcomputer 13 to find the difference between the load current and the reference value and by adding this difference to the voltage command, the voltage command is then corrected by the load current value corresponding to the load change of the brushless DC motor.

Title: Automatic adjustment method/device for clock timing
Inventor: KUBOTA NOBUYOSHI
IPC: H03K5/131
Filed: 1994-10-03
Abstract: PURPOSE: To automatically adjust the timing errors and to eliminate the labor and time needed for the timing adjustment by reading the data out of a memory with change of the clock delay time to detect the errors for each delay time and defining a clock of a small error rate as the optimum delay time to apply it to the fetching of the following data.

A delay circuit 10 placed at the clock line side has the output lines 11 to 18, and these data lines have different delay times. A selector 19 successively selects the outputs of lines 11 to 18 in a test mode to give these outputs to the F/F 3 and latches data to store them in a memory 9 via a data line 8. Then the data are read out of the memory 9 for each delay value and then judged for detection of the error rates. The optimum delay value of the smallest error rate is calculated to each delay value among those repetitively detected error rates. The selector 19 is fixed to the relevant delayed clock, and a clock having the optimum delay value is selected and the data are latched.

Filed: 1986-10-09
Abstract: PURPOSE:To reduce the load effect of signal lines of a low-speed measurement system by connecting the signal line of a high-speed measurement system and the signal lines of the low-speed measurement system to pin connection terminals in parallel. CONSTITUTION:Parts of the signal lines 12 and 13 of the low-speed measurement system which are closer to a pin connection terminal 10 than relay contacts K3 and K4 are connected together to one common signal line 16. Then, a relay contact K5 is interposed in the middle of the line 16 as closely to the terminal 10 as possible. Further, the contact K5 is opened by a relay control part at the time of a fast test. When this contact K5 is opened, the signal lines 12 and 14 of the low-speed measurement system is connected to the terminal only at the short part of the line 16 shown by a broken line 18. Thus, the signal line part which is a load is shortened greatly and the part is only one line, so the load effect is reduced greatly.

Title: Inter-base station frame synchronizing system
Inventor: MORIKURA MASAHIRO
IPC: H04W56/00
Filed: 1992-09-08
Abstract: PURPOSE:To prevent the frame phases of all the base stations from drifting hourly by measuring the time difference of the frame phases at both base stations, and correcting a transmission timing so that the time difference can coincide with each other. CONSTITUTION:The time difference t1(n) of the frame phase measured at the base station BS1 and the time difference t2(n) measured at the base station BS2 simultaneously are transmitted on (n+1)th frames to an opposite base station, respectively. Each base station compares t1(n) with t2(n). For example, when relation t1(n)>t2(n) can be satisfied, it shows that the frame phase of the base station BS2 lags behind the base station BS1, and the base station BS1 applies no correction of the frame phase on an (n+2)th frame. Meanwhile, the base station BS2 also compares t1(n) with t2(n) simultaneously. Delay is corrected on the (n+2)th frame from relation t1(n)>t2(n), and an operation is performed so as to synchronize the frame phase of the base station BS2 with that of the base station BS1.

While an opening part 15 for V groove formation is etched by using the formed photoresist 14 as a mask, a V groove 16 is formed on the surface of the silicon substrate 11. Next, after the photoresist 14 is removed, a Si3N4 film 17 on the substrate 11's surface inclusive of inner walls of the V groove 16 is etched to perfectly remove the Si3N4 film 17 existing on the flat surface part of the silicon substrate 11 and the flat bottom part of the V groove 16. Next, a thick oxidizing film 18 is formed on the surface of the substrate 11 and the bottom part of the V groove 16. At that time, because the sides of the V groove 16 are masked with the Si3N4 film 17, an oxidizing film is not formed. Next the sides of the V groove 16 are exposed by an etching method to perform oxidation again.
