Title: Tracking device for turning direction of sonar
Inventor: YOSHIDA TAKASHI
IPC: G01S15/66
Filed: 1980-07-08
Abstract: PURPOSE:To realize a full-circumference tracking, by actuating a discontinuous part of a tracking device as if it is of the continuous property. CONSTITUTION:For instance, when either one of potentiometers 3 and 5 reaches point A during their turning to left, a gap entrance detecting circuit 19 transmits a high-level output to cur off a high-level output signal sent from a phase control circuit 17. The transmission pulse of a pulse generating circuit 27 is led to an input terminal of an AND circuit 14, and accordingly the pulse given from a pulse generating circuit 15 is led to a motor drive circuit 16. On the other hand, an OR circuit 24 transmits a high-level output to secure the control as if the circuit 16 makes a pulse motor 7 turn to left. when a slider 302 of the potentiometer 3 reaches point B, the compensating action completes with the high-level output given from a gap exit detecting circuit 20. In such constitution, a full-circumference tracking is possible.

Abstract: PROBLEM TO BE SOLVED: To provide an effective wiring material, excellent in bending durability, which can cope with a thickness limit, by interposing a plurality of flat type conductors by two sheets for insulating films formed with a bonding agent layer, and limiting a respective constitution of thickness. SOLUTION: In a plurality of parallelly arranged flat type conductors 1, by two sheets for insulating films 2 formed with a bonding agent layer in one surface, the bonding agent layer 3 is interposed inside. Here, thickness Ti of the insulating film 2 and thickness Tc of the flat type conductor 1 are formed so as to satisfy a relation, 0.3<= Ti/Tc <=1. In the rectangular conductor 1, pure copper or copper alloy is used, the thickness Tc is set to 50 to 100μm so as to satisfy a relation, Wc/Tc <=35, (Wc: width), and a relation, 0.3<= Ta/Tc <=0.7, (Ta: thickness of the bonding agent layer 3). Thus by limiting thickness of the insulating film, the flat type conductor and the bonding agent layer, a flat cable excellent in flexing durability is obtained. Accordingly, in the case of providing a limit in conductor thickness, an effective wiring material is provided.

Title: Displacement amplifying mechanism for piezoelectric element and driving method therefor
Inventor: OYA KAZUMASA
IPC: H01L41/09
Filed: 1993-04-22
Abstract: PURPOSE:To provide a miniature amplifying mechanism excellent in high speed response at low cost wherein the amplification factor of one piezoelectric element is equal to or lower than that of a conventional piezoelectric displacement amplifying mechanism. CONSTITUTION:An amplifying part comprising two buckling springs 2A/2B welded into a ring is boded directly to two driving end faces 3a/3b of a piezoelectric element 1 generating distortion through piezoelectric effect depending on a driving voltage being applied externally. Distortion of the element 1 in the direction of an arrow A is amplified by the elongation of the buckling springs upon elongation of the element 1 and the displacement in the direction of an arrow B is taken out from the bridge-like apex of the buckling springs 2A/2B thus decreasing the number of components as compared with a conventional mechanism where the amplification is carried out in two stages through a lever arm. Two piezoelectric may be fixed to the outside of the amplifying part in order to compress the buckling springs. The buckling springs may have asymmetric shape and may be odd in number.

Abstract: PURPOSE:To ensure that significant cost cut and remarkable yield improvement can be achieved by providing a constitution in which the temperature of a recording head is estimated based on a temperature of an electronic element which drives a thermal energy generation element of a recording head. CONSTITUTION:When a predetermined pattern is continuously recorded in a recording medium to measure the temperature of a base plate of a recording head and that of a power transistor 8a simultaneously, the temperature of the power transistor 8a increases in proportion to that of the recording head 2. Then the temperature of the recording head 2 is measured by recording the temperature of the power transistor 8a using a temperature sensor 9. In addition, it is ensured that the temperature of the recording head 2 is decided readily based on the temperature of the power transistor 8a by selecting between power transistors so that the thermal capacity of the power transistor 8a becomes the same as that of the recording head 2 or junctioning a heat release plate or calculating the temperature of MPU 17 in such a manner that it is corrected. Subsequently, a variation in temperature measurement of the recording head can be eliminated and thereby a significant cost reduction and a remarkable yield improvement are ensured.
