Title: Azimuth sensing device
Inventor: ANDO NORIYOSHI
IPC: G01C19/38
Filed: 1991-11-13
Abstract: PURPOSE:To sense accurate azimuth at all times without being influenced by any magnetical obstacle. CONSTITUTION:An angular velocity sensor 21 is arranged with its rotary shaft positioned level and secured onto a turntable 13 which is rotated by a motor 12. The sensor 21 senses the angular velocity due to rotation of the earth round its own axis and emits an angular velocity signal varying in sine wave according to the azimuth in which the rotary shaft is directed. A rotational position sensor 31 senses the reference rotational position of the turntable 13 in cooperation with slit 13a. The period from the time, when the angular velocity signal indicates the reference azimuth, to the time, when the reference rotational position is sensed. is measured by counting the pulse train signals of frequency proportional to the revolving speed of the turntable 13. Thereby the deviation angle from the reference azimuth to the rotational position of a case 11 is measured, and azimuth corresponding to this rotational position is sensed.

Abstract: PURPOSE:To improve workability, preventing a conduit from being damaged at a contact part by winding a strip-shaped sheet in a spiral form on a conduit and fixing both the end parts of a sheath pipe which is externally fitted around the strip-shaped sheet, on the strip-shaped sheet or the conduit. CONSTITUTION:After a strip-shaped sheet 2 is wound in a spiral form in a superposed state at a part on a gas pipe P, both the end parts are fixed by a tape.

Abstract: PURPOSE:To surely detect the end of a toner with accuracy through simple constitution without requiring much space by providing a piezoelectric sound or resonance type powder sensor and an oscillating circuit and comparator for oscillating piezoelectric elements on both sides of the sensor and detecting the reception state of each piezoelectric element. CONSTITUTION:When an oscillation side piezoelectric element 19A is oscillated at a frequency of e.g. 1140 Hz from an oscillating circuit 20 and one side of a tuning fork is vibrated by the oscillation side piezoelectric element 19A from an output terminal 20A, the other side of the tuning fork resonantes at a predetermined frequency 1140 Hz and starts to oscillate if no toner 4 exists. The other side of the tuning fork does not oscillate when the toner 4 exists. A signal piezoelectrically converted from a reception side piezoelectric element 19B is given to a detection terminal 20B according to whether or not the toner exists and the signal is compared with a reference toner level by a comparator 20 and converted to a digital signal and a signal indicating whether or not the toner exists is output to an output terminal 20E. Therefore the end of the toner can be easily detected simply by setting the open portion of the tuning fork 18 in a position of a toner level at which images losses do not occur.
