Title: Thin film magnetic head
Inventor: KAMINAKA NOBUMASA
IPC: G11B5/39
Filed: 1983-06-13
Abstract: PURPOSE:To stabilize the magnetization structure at the tip part and to improve the characteristics for reproduction of short wavelength with a thin film magnetic head, by providing a shielding magnetic material having zero or negative magnetostriction constant at least at a single side of the thickness direction of the thin film of a magneto-resistance effect element having positive or zero magnetostriction constant. CONSTITUTION:A double shielding type MR head contains magnetic materials 7 and 8 set at both sides of an MR element thin film 6. The material 7 serves as a substrate for growth of a thin film element; while the material 8 must have a high level of permeability as a shielding material with a desirable magnetostriction constant lambda which is zero or negative. The film 6 has positive or zero constant lambda and is provided in the medium driving direction (y) and also in the direction where the thin film surface crosses the medium recording surface. The average direction of a spin Ms of the film 6 is set with a tilt to a current (i) flowing through the film 6 by an angle theta, i.e., in the direction where the magnetization facilitating axis exists. Then the angle theta is properly controlled to ensure a linear motion.

Abstract: PURPOSE: To improve reduction of a torque at the time of high speed rotation by forming an opening part which is opened in the vicinity of a bottom dead point, and arranging an automatic valve on the outer side of the opening part, in a four cycle internal combustion engine. CONSTITUTION: A hole is formed on the cylinder 1 of a four cycle internal combustion engine so as to open while between the period of a bottom dead point and the period of a top dead point in association with descent of a piston which is fit to the cylinder 1, and the hole is formed as an opening part 2 which communicates with a second exhaust port 5. A poppet valve 3 is provided on the outer side of the opening part 2 so as to close by being brought pressure- contact with the opening part 2 by spring force of a spring 4, and the poppet valve 3 is formed as an automatic valve. The rigidity of the spring 4 for the automatic valve is set to a value sufficiently lower than the value of cylinder pressure at the time of the final period of an expansion stroke in a high load.  It is thus possible to obtain a same effect as that the opening area of an exhaust valve is increased, in the vicinity of the bottom dead point time at the time of high speed rotation so as to reduce a torque at the time of a high speed rotation.

Title: Multidimensional vector identification method
Inventor: WATANABE SUMIO
IPC: G06N3/08
Filed: 1991-05-10
Abstract: PURPOSE:To shorten learning time, to shorten calculating time and to improve a recognition rate by executing affine transformation to a vector to be identified and transforming the vector to be easily learnt by a neural network in the case of identifying the vector in a Euclidean space. CONSTITUTION:First of all, a reference vector [Si] is calculated for each desired category to be identified. Next, a primary transformation matrix A is prepared to transform an N-dimensional vector to an M-dimensional vector. In this case, the primary transformation simultaneously executes orthogonal projection to a space, where the reference vector [Si] is spread, and the orthonormalization of the reference vector [Si], and the vector obtained in this way is suitable as the input of the neural network. Afterwards, an M-dimensional vector A[Si] obtained in a step 2 is inputted to the neural network and learnt by a back propagation method. Thus, since the neural network executes according to an inner product and nonlinear transformation, in the case of learning orhtogonal inputs, they can be completely learnt by the back propagation method.

Title: Control system
Inventor: AKAI SO
IPC: G05B15/02
Filed: 1989-04-25
Abstract: PURPOSE:To obtain a control system having its stable working and having no data transfer error even at abnormality of the supplied voltage by securing a constitution where a 2nd bus repeating device detects the DC power voltage to output a power fail signal when the detected power voltage is lower than a prescribed level and a 1st bus repeating device transmits the power fail signal to a processor part. CONSTITUTION:When service interruption occurs at the process I/O power units PS1 - PSm which supply the DC power to the process I/O IO11 - IOmn and the 2nd bus repeating devices NC1 - NCn, the service interruption is detected by a voltage detecting part of the 2nd bus repeating device. Then a driver part transmits a power fail signal to a processor part PC via a system bus and a 1st bus repeating device SI. The part PC receives the power fail signal via the device SI and discontinues its control action. Thus the errors can be prevented when the data are transferred to the process I/O from the part PC at the service interruption caused by the insufficient supply of power. Then it is possible to attain a control system which is not easily influenced by the power supply fluctuation.

Title: Production of high tension sheet steel parts of postheat treatment type by detonating pressure
Inventor: YOSHIHARA NAOTAKE
IPC: B30B5/00
Filed: 1993-04-09
Abstract: PURPOSE:To repeatedly operate safely and in short time and to manufacture high tension sheet steel parts of postheat treatment by the high pressure of detonation. CONSTITUTION:A combustion chamber 1 is so designed that the cross section gradually decreases from one end 1A as flame progresses, a convergence part having the smallest cross section is formed in the other end 1B, and the end face of a pressure medium in a pressure chamber 12 is faced at the opening of the other end 1B. Pressure is raised because the cross section of the combustion chamber becomes smaller as the flame inside the combustion chamber 1 progresses, and the pressure becomes extremely high at the other end 1B. This high pressure is converted to the pressure medium inside the pressure chamber 12. On a die 16, a high tension sheet steel which is made to have a high strength in a heat treatment after receiving a primary forming is arranged, and the high tension sheet steel P is pressed with the die 16 through the pressure medium and is formed (straightened) into the final prescribed shape.

Filed: 1981-07-07
Abstract: PURPOSE:To prevent a junction breakdown in a semiconductor integrated circuit device by arranging a depletion type Tr around a contact as a high resistance region, and alleviating a current concentration in a P-N junction in the vicinity of the contact at the time of applying an excessively high input. CONSTITUTION:A P<+> type diffused layer 14, an Si oxidized film 15 and an N<+> type diffused region 16 are sequentially formed on a substrate 13, and a depletion type TrD of polysilicon gate P0 is formed in ?-shape to surround a contact CH of the region 16 with an input pad 18. A high resistance region requires a large area, but high resistance is obtained in an ultrafine area by substituting a load resistance T2 for the Tr4 by shortcircuiting the gate and the drain, thereby using the Tr as a high resistance region. In this manner, the junction breakdown at the time of applying an excessively high input can be prevented.
