Title: Magneto-optical recording medium
Inventor: MIZUTANI TADASHI
IPC: H01F10/13
Filed: 1989-02-15
Abstract: PURPOSE:To obtain a magneto-optical recording medium which enables good recording/erasing even in a low bias magnetic field by constituting the recording layer of a specific amorphous metal thin film having the easily magnetizing axis perpendicular to the film surface. CONSTITUTION:The magneto-optical recording medium has the recording layer of an amorphous film having the easily magnetizing axis perpendicular to the surface thereof and the composition expressed by (Nd,Pr)x(Smz(TbDy)1-z)y(Fe, Co, Ni)100-x-y, wherein x, y and z satisfy the formula I. Proportions of the amounts of Fe, Co and Ni can be arbitrarily controlled according to the conditions of recording/erasing for the medium so as to obtain desired values of physical properties such as Curie temp. and compensation temp. However, to obtain a perpendicularly magnetized film, which is the requirement for the magneto-optical recording medium, from the composition above described, it is necessary to make the proportion of total rare earth elements (x+y) in the film in the range from 15at.% to 40at.%. Thus, the obtd. recording medium enables good recording/erasing even in a low bias magnetic field.

IPC: B41J2/01
Filed: 1989-02-14
Abstract: PURPOSE:To stabilize performance of discharge by eliminating clogging of an orifice by a method wherein an amount of Si or Ti among elements which are eluted from a structure member of a head into recording liquid is taken as 15ppm or under. CONSTITUTION:When a member composing a liquid jet recording head is brought into contact with recording liquid under conditions of 1,000h and 50 deg.C, an elution amount of Si and Ta contained in this member, especially in a protective layer 34 into the recording liquid is taken as 15ppm or under, an in an optimum manner as 10ppm or under. Consequently, clogging of an orifice for discharging the recording liquid as a liquid drop by operation force of a thermal energy operating part in a bubble jet type liquid jet recording head can be prevented from occurring.

Title: Mis-type semiconductor integrated circuit device
Inventor: UCHIBORI KIYOBUMI
IPC: G11C11/412
Filed: 1978-03-29
Abstract: PURPOSE: To ensure output of the signals with the compensated level regardless of the fluctuation of the power voltage by using the resistance semiconductor element featuring the resistance value reduced with lowering of the substrate voltage to the load resistance.  
     CONSTITUTION: Si field oxide film 2 is coated on P-type Si substrate 1, and n-type source region 8 and drain region 9 are provided to substrate 1. And gate electrode 5 composed of n-type poly Si is provided via thin Si oxide film 3A, thus obtaining the MISFET. While the resistance composed of poly Si layer 6B is provided on substrate 1 via thin Si oxide film 3B. This resistance is affected by the electric field from the substrate since film 3B is thin, and thus the resistance value reduces with decrement of back bias voltage VBB applied to electrode 14. Accordingly, in case power voltage VDD applied to terminal 13 reduces and thus VBB decreases via the inverter circuit comprising the series circuit of the MISFET and the resistance on the substrat, the threshold voltage of the MISFET lowers. At the same time, the resistance value of layer 6B is reduced to compensate the logic threshold voltage of the circuit.

Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To progress the expansion of an airbag smoothly and surely and dissolve the drop of an appearance quality by forming a multi-layer structure consisting of an other layer with a specific tensile elongation and an inner layer, integrally piled on the inside surface of this outer layer, whose tensile elongation is higher than that of the outer layer and giving a brittle part to the inner layer. SOLUTION: An instrument panel is composed of a base material 1 made of polypropylene, a foaming body layer 2 consisting of a polyurethane foaming body piled on the surface of the base material 1 and a skin 3 piled on the surface of the foaming body layer 2. On the inner layer 31, a H-shaped slit (brittle part) 32 is formed on a position corresponding to a slit 10 and the foaming body layer 2 is filled in the slit 32. When a big tensile stress is exerted on the inner layer at the airbag expansion time, the inner layer is cleaved easily at the brittle part 32. When a force is transmitted to the outer layer, as the tensile elongation of the outer layer is low like 70 to 170%, the inner layer is broken easily at the position of the brittle part 32. Thereby, the airbag is expanded in a car room.

Filed: 1983-03-07
Abstract: PURPOSE:To make the automatic adjustment of azimuth angle possible by using a head having two auxiliary head gaps to detect the difference in output between auxiliary head gaps and controlling an electromechanical conversion element in accordance with this output difference. CONSTITUTION:Auxiliary head gaps G1 and G2 are placed at angles theta1 and theta2 (¦theta1=theta2¦) to a main head gap G3, and the gap G3, is provided at right angles to the lengthwise direction of a magnetic tape 4. When a magnetic head 14 reproduces a part of a pattern PB, the extension of the gap G3 is placed in a position A and the output of the gap G3 is reduced because the magnetic head 14 is held in the state indicated by a solid line. Because of the deviation of azimuth angle, the output of the gap G1 is increased, and the output of the gap G2 is reduced furthermore. As the result, a positive-direction output S4 is transmitted from a detecting circuit 44, and a driving circuit 45 applies a control voltage of such direction that a thickness (t) of a piezoelectric element 11 is reduced, and the head 14 is adjusted to the position B where it coincides with the pattern PB of the gap G3.
