Title: Optical pickup
Inventor: NAKAMURA HIROYUKI
IPC: G02B27/09
Filed: 1984-05-16
Abstract: PURPOSE:To improve the performance of the optical pickup by an inexpensive device by arranging a parallel flat plate between a semiconductor laser and a collimator lens slantingly to the optical axis. CONSTITUTION:The parallel flat plate 4 is arranged between the semiconductor laser 1 and collimator lens 3 slantingly to the optical axis. When the laser 1 is seen in directions (a) and (b), light beams emitted at positions O1 and O2 travel as if they were emitted at positions O1' and O2' through the operation of the flat plate 4. At this time, the positions O1 and O1', and O2 and O2' are difference and the differences are varied optionally according to the thickness and inclination of the flat plate 4, so the positions O1' is made coincident with the position O2' to compensate astigmatism. Thus, no expensive cylindrical lens is used, so the cost is reduced and the overall aberrations are reduced.

IPC: B22D11/115
Filed: 1988-04-22
Abstract: PURPOSE:To obtain a large thrust by forming the core having more than a pair of the outside inductors arranged on the side wall outer periphery of a melting tank and the conductor stored in the coating protection cylinder made of a refractory material composed by running along the center axial line at the inner part of the melting tank. CONSTITUTION:A pair of the inductors 3, 3' mutually opposed on the outside circumference of a furnace wall 4 and a core 5 are located at the center part around the shaft center of a melting tank and extended from the position slightly higher than the upper face of a molten metal 2 up to the position higher than the bottom face of the melting tank. The core 5 is made by inserting the conductor 6 into the inner face of the coating member 5' in the shape of the bottomed cylinder made of a refractory material. The electromagnetic stirring power is increased by locating the conductor at the center part of a furnace body, reducing the attenuation of the magnetic flux which has been generated inevitably in the past and penetrating a strong magnetic flux equally in the molten metal. The capacity of the conductor is thus miniaturized and the designing and manufacturing are enabled without fluctuating melting and molten metal pouring devices largely.

Title: Magnetic head
Inventor: TOGAWA EIJI
IPC: G11B5/31
Filed: 1985-05-09
Abstract: PURPOSE:To produce inexpensively a stable head having large output by adjusting the Ni compsn. of the magnetic core of a thin film magnetic head of which the magnetic core is formed of an Ni-Fe binary alloy to the ratio within a prescribed range. CONSTITUTION:The magnetic core of this thin film magnetic head is formed of the Ni-Fe binary alloy by using an electroplating method. The Ni compsn. of such magnetic core is adjusted to 81.6-83.0%. Magnetic restriction is zero at about 81.5% compsn. of Ni in the Ni-Fe binary 'Permalloy(R)'. On the other hand, the crystal magnetic anisotropy has the min. value as well with the same compsn. as the compsn. with which the magnetorestriction is zero. The magnetic anisotropy larger than the shape anisotropy must exist stably even in a heating stage in the process for production in the case for forming the magnetic core of the thin film magnetic head. The magnetic anisotropy provided by the impression of an external magnetic field is stable at 81.6-83.0% Ni by weight of the 'Permalloy(R)' compsn. The magnetic anisotropy is small and unstable at <81.6% Ni compsn. and the magnetic anisotropy increases but the magnetorestriction increases and such is undersirable when the compsn. exceeds 83.0%.

Title: Inspection of soldered connection
Inventor: SAKAGUCHI MASARU
IPC: G01R31/04
Filed: 1984-05-18
Abstract: PURPOSE:To make it possible to certainly inspect that a substrate and a chip are perfectly soldered, by measuring the temp. rising and falling characteristics of the terminal part in the substrate and the chip and the vicinity thereof when heat energy is loaded to the terminal part of a connection part. CONSTITUTION:When heat energy Q is loaded from one terminal of a chip 2, the temp. of the chip 2 rises and the heat thereof reaches solder 6 through a connection terminal 4. Herein, the heat is directly transmitted to the connection terminal 10 in the side of a substrate at the connection part and the point A of the under surface of the terminal part begins to rise in its temp. with slight time delay as compared with the load of energy Q and the temp. rising degree at said point P is large. In the other connection part, a heat conductive degree is largely lowered because there is a gap between the solder 6 and the terminal 10 and the temp. rising degree of the terminal 10 in the side of the substrate becomes small. A curve (a) shows the temp. characteristic at the point A in the connection part and a curve (b) shows the temp. characteristic at the point A in the other connection part. As is apparent from the foregoing, the abrupt temp. rising characteristic is obtained in the perfect connection part and that in the imperfect connection part is small and the quality of connection can be grasped.

Abstract: PROBLEM TO BE SOLVED: To enable a device to immediately perform behavior control in accordance with a steering angle even by not detecting a neutral position when an engine is started, in this case, so as to prevent also generation of hunting. SOLUTION: In a calculating part 20, during the time a neutral position is not detected based on a signal of a sensor 16, and a steering angle can not be detected, a steering angle memory value when an engine is stopped, and a steering amount calculated from an integrated value of number of pulses from the sensor 16 after the engine is started, are added, and a steering angle estimated value is obtained.
