Title: Driving system of azimuth sensor
Inventor: ITAKURA TOSHIO
IPC: G01C17/30
Filed: 1983-06-14
Abstract: PURPOSE:To obtain an azimuth sensor of high precision by a system wherein an exciting current for detection of azimuth, which is made to flow through an input-side coil of a head, is restricted in one direction so as to detect a geomagnetic component. CONSTITUTION:An exciting current, which is made to flow through an input-side coil, is restricted in one direction so as to detect a geomagnetic component. Since a flowing magnetic flux is designated in one direction according to such a driving system, it is possible to obtain the azimuth of high precision without necessitating the strictness in the symmetry of a tape wound core employed. More particularly, the exciting current is restricted in one direction by grounding one end of a primary coil 1, and the geomagnetic component which appears when a pulse falls is detected through a switching gate. An azimuth sensor head is formed by coiling a Co-amorphous thin tape on a cylindrical bobbin and winding the toroidal primary coil 1 thereon and further a secondary coil 2 thereon, respectively. In the head thus prepared and set, the exciting current is made to flow in one direction of the primary coil 1, and an output appearing when the pulse falls is detected through the switching gate.

Title: Liquid chamber volume variable type two port connection valve
Inventor: YAMAZAKI HIROSHI
IPC: F16K31/02
Filed: 1982-06-20
Abstract: PURPOSE:To prevent the dripping at the shut-off of fluid from occurring by a constitution wherein the volume at outflow side is increased at the closing of a valve body to open and close a flow passage between an inlet port and an outlet port. CONSTITUTION:In the valve applied to an ink jet printer, with the valve on, an electrostrictive oscillator 11 deforms itself maximally at the center, resulting in letting a push pin 13 push the valve body 23 downward against a spring in order to keep the valve body 23 from a valve seat 14. Consequently, ink flows from the inlet port 21 to the outlet port 22 in order to be supplied to an ink jet head. Next, when the valve is turned off, the electrostrictive oscillator 11 returns to the flat state, resulting in firstly bringing the valve body 23 into contact with the valve seat 14 to stop the flow of the ink in this case. Secondly, the return of the oscillator 11 to its flat state causes the volume in a liquid chamber 15 to increase and consequently negative pressure is applied to the outlet port 22 side, resulting in preventing the dripping of ink from the jet head from occurring.
