Title: Method for adjusting phase of optical rotational angular velocity sensor
Inventor: KUMAGAI TATSUYA
IPC: G01C19/72
Filed: 1990-11-30
Abstract: PURPOSE:To improve the phase adjusting accuracy and to improve the reliability of the accuracy of an optical rotational angular velocity sensor by fixing the phase of a synchronous signal, shifting the phase of a phase modulation signal, and adjusting the phase so that an output of second higher harmonics becomes maximum. CONSTITUTION:A reference wave fr, a synchronous signal 2fr of second higher harmonics, and a synchronous signal 4fr of fourth higher harmonics are fixed. Only the phase of a phase modulation signal fm is changed by rewriting the data given to a timer 14. While the output of the signal 2fr is monitored, the phase of the signal fm is shifted and adjusted so that the output becomes maximum. Then, while the output of the signal 4fr is monitored, the phase is adjusted so that the output becomes maximum. A series of the operation is automatically performed according to a program from a CPU 10. Accordingly, the time for adjusting the phase is shortened, and the circuit scale is reduced because of the one-phase arrangement. The cost is saved.

IPC: E04B2/90
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of watertightness inside of a horizontal frame without impairing external appearance design by joining a throating to the horizontal frame of a sash frame, and forming a ventilating passage communicated up to the inside of a room from the outside of the room by the throating. SOLUTION: A sash frame 2 is arranged at an outside air introducible interval between a throating 4 and the upper end of a panel 1 on the outer wall panel 1. Next, after a load receiving bolt 7 is screw-fitted in the upper end of the panel 1, the throating 4 is placed. At this time, a depth piece 41 is brought into close contact with a gasket 8, and watertightness is secured. Next, a space between an under surface of the depth piece 41 and the upper end of the panel 1 is communicated with a space between an under surface of the throating 4 and an upper surface of the depth piece 41 through a notch 45. Its space is communicated with the inside of a room through a space with face pieces 31 and 42, and forms a ventilating passage. A cap 9 is slidably installed in a lower frame 3, and an opening 91 is switched.  Therefore, since there is no need to form a ventilating port in a horizontal frame, the deterioration of watertightness inside of the horizontal frame 3 can be prevented.

SOLUTION: The housing holes of a rack 30 are loaded with tubes 40 and, in this state, the shaft 24 of a basket 20 is fitted in the groove 31 of the rack 30 to support the rack 30 by the basket 20. In this state, the bottom surface 30a of the rack 30 is seated on the decking of the basket 20. When a rotor is rotated, the bottom part of the rack 30 is shaken outwardly along with the basket 20 by the centrifugal force of the rotor. At this time, the rack 30 is integrated with the basket 20 because the bottom surface 30a of the rack 30 is in contact with the decking 22 of the basket 20 and the shaft 24 is fitted in the groove 31. When centrifugal separation work is completed by this constitution, the rack 30 is taken out of the basket 20 along with the tubes 40.
