Title: Magnetic sensor and its production
Inventor: HOSHIYA HIROYUKI
IPC: G11B5/39
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To deal with high density recording by heat-treating a substrate under applied stress, regulating strain relief direction for an antiferromagnetic film in which strain is developed by the heat treatment in accordance with the stress applying method and the magnitude of the stress and attaining crystal anisotropy in a prescribed direction in the surface of the substrate. SOLUTION: A substrate holder 52 deforms a substrate 50 through a spacer 51 that applies strain to the substrate 50 to apply stress to the surface of the substrate 50. A spin valve laminated film is formed on the substrate 50 and the substrate 50 is fixed in the holder 52 and heat-treated. By this heat treatment, appropriate stress is applied to the spin valve laminated film and the strain of an antiferromagnetic film is led to the direction of the stress. In other way, the substrate 50 is fixed in the holder 52, the spin valve laminated film is formed and the substrate 50 is released from the holder 52 and heat-treated after the substrate 50 is relieved of the stress and stress in the reverse direction is applied to the spin valve laminated film.

Title: Measuring device for motion speed
Inventor: MIWA HIROHIDE
IPC: A61B8/00
Filed: 1980-02-08
Abstract: PURPOSE:To measure the speed component, etc., of a three-dimensional body accurately by irradiating the body with three or more kinds of ultrasonic-wave beams differring in quality in different directions so that they will pass through one part of the body at the same time, and then by performing arithmetic by discriminating respective reflected beams. CONSTITUTION:For example, ultrasonic-wave vibrators 11-13 are three different vibrators and opposed to one blood-flowing part P in the viscera. Ultrasonic-wave pulses emitted from vibrators 11-13 have respective delay times controlled to pass through point P at the same time. Respective ultrasonic-wave beams reflected at measurement point P are converted by ultrasonic-wave vibrators 11-13 into electric signals, which are transmitted to discriminating filter 30 via amplifier 20 to be separated by three filters into three kinds of electric signals corresponding to three kinds of ultrasonic waves. Respective separated signals are passed through gate circuit 40 to extract only reflected signals, which are passed through Doppler shift detecting circuit 60 to detect their frequency shift quantities, and then they are sent to speed arithmetic circuit 70 to calculate respective motion speed components. Thus, the accurate measurement can be performed.

IPC: C23C18/16
Filed: 1982-02-01
Abstract: PURPOSE:To partially form a metal coating layer on an Al matrix having a complicated shape at a high speed, by a method wherein a metal coating part is formed on the local part of an Al surface by using metal halide and, after a chemical forming film is formed only on the Al surface, electroless plating is applied thereon. CONSTITUTION:After sticky vaseline is thinly applied to the part of the surface of an Al material, a fine powder of metal halide such as copper halide or tin halide are scattered thereon and, after th whole is heated to a temp. generating substitution reaction between metal halide and Al or more, the residue is removed by washing. By this method, the Al material locally coated with different kind metal is obtained. In the next step, the treated Al material is thrown  into a treating liquid prepared by hot pure water or aqueous ammonia to 80 deg.C  or more to form a dense protective boehmite coating film. Finally, coated metal is activated according to necessity and the activated Al material is immersed in  an electroless plating liquid to apply plating to the Al material and the different  kind metal. The plated material is thereafter washed and dried.

Title: Compound semiconductor integrated circuit device and its manufacture
Inventor: TOSAKA NORIO
IPC: H01L21/822
Filed: 1991-02-06
Abstract: PURPOSE:To increase the capacitance per unit area of a capacitor, and obstruct the gate current of a compound semiconductor field effect transistor. CONSTITUTION:An oxide film 7 formed by directly oxidizing a compound semiconductor substrate 1 is used as the dielectric film of a capacitor. Thereby a very thin dielectric film can be formed, as compared with the one formed by an ordinary CVD method, so that a capacitor having large capacitance can be realized. By using a GaAs oxide film formed by projecting a light in an oxygen atmosphere as a gate insulating film, the gate current is obstructed. Hence the surface level is lowered, and characteristics control of a transistor is enabled.

Abstract: PURPOSE:To easily take out a jammed document by forming a separating belt of an endless belt and also rotatably supporting the separating belt by a plurality of belt supporting members and connecting one of them to a drive motor through a clutch and also mounting a spring to the other one of the members. CONSTITUTION:Whether a jam is generated or not is judged by whether a document D is detected or not by a sensor 45 within a predetermined time after a feed of the document D on a document table 13 is started by a call roll 32 and when the jam is generated, a clutch 17 is placed in its off-condition, and a pulley 14 is placed in its free condition by releasing a drive motor 18 from its connection to a pulley shaft 26 formed integrally with the pulley 14.

Abstract: PURPOSE: To prevent dust flow into a bearing by flowing a part of return guide vane side high-pressure gas from a return flow course of a shell of a fixing guide plate among the base of the fixing guide plate, the base of the fan, and the basic plate of the fan, not through in the bearing.  
     CONSTITUTION: High pressure gas discharged from a fan 15 passes through a diffuser 31 and an air duct of a return guide vane 32 and flows fron an air vent 24 of a bearing supporter 14 into a motor. A part of the gas flows back from a small gap between the connection piece 38 of the fixing guide plate 16 and a shell 33 because an atmospheric pressure between the basic plate 60 of the fan 15 and the base 29 of the fixing guide plate 16 is lower than the space on the return guide vane 32. As  a part of high-pressure gas including fine dust flowing into the motor 1 is prevented from running back through the internal of the bearing 12 into upper stream of the fan, no fine dust may from lodging in the bearing 12.

Title: Marker signal generating method for spectrum analyzer
Inventor: FUNADA TAKAYOSHI
IPC: G01R13/30
Filed: 1990-01-26
Abstract: PURPOSE:To generate a marker signal without affecting adjacent radio equipments by inputting the signal which is made to be an image frequency to a local oscillating frequency of input frequency, to a high frequency circuit from a marker signal generator. CONSTITUTION:In the case the frequencies to display the spectrum are expressed as from f1 to f2 and the intermediate frequency is fif and the sweep local oscillating frequencies are from f1+fif to f2+fif, the frequency of marker signal generator 8 is set to f3+2fif which is the image frequency, not to f3, to display the marker at the position of f3 locating between f1 and f2. Since the frequency difference between the input signal S and local oscillating signal is outputted by a frequency converter 3, the intermediate frequency fif is generated also to the image frequency f3+2fif as the difference to the local oscillating fre quency f3+fif, therefore, this case is no difference with that the f3 is generated as the marker signal. Consequently, the intermediate frequency signal fif as well as the input signal S can be generated by means of generating the image frequency signal f3+2fif by the signal generator 8, so the usage as the marker signal for input signal S can be available in a spectrum display device 7.
