Title: Multipoint radiation type sound pressure control device
Inventor: MIYOSHI MASATO
IPC: H04R3/04
Filed: 1985-03-18
Abstract: PURPOSE:To create the desired sound pressure distribution by controlling input signals to a speaker element so that the sound pressure waveform at the controlled point relative to the sound wave radiated from the speaker element will satisfy the prescribed signal transmission properties. CONSTITUTION:The speaker elements 11-1S are placed at plural points in the space. To these speaker elements 11-1S are supplied the same input signals through separate filters 211-21S. In the same space as that occupied by the speaker elements 11-1S are provided the points to be controlled 111-11N the signal transmission properties of which are set to desired values. An arithmetic setting unit 80 calculates the coefficients of the respective filters 211-21S using these signal transmission properties and the signal transmission properties between the speaker elements 11-1S and the points to be controlled 111-11N. A filter coefficient setting unit 100 sets its coefficient to that of the corresponding filters 211-21S. As a result, the input signals are controlled so as to satisfy the desire signal transmission properties between the points to be controlled 111-11N.

Title: Heat conductivity and temperature measuring probe and its manufacture
Inventor: NAKAMURA ARATA
IPC: G01N27/18
Filed: 1988-03-07
Abstract: PURPOSE:To attain reinforcement to heat stress by laminating a green sheet where a thin wire part and electrodes are wired on >=2 green sheets which are laminated into an insulating substrate and laminating and sintering a green sheet thereupon. CONSTITUTION:The green sheet where the thin wire part 25 of 0.2mm width and 80mm length and electrode parts 21, 22, 23, and 24 are printed and wired is laminated on the insulating substrate consisting of a green sheet 27 or 0.3mm thickness. Then the green sheet 26 or 0.3mm is stacked thereupon and sintered at the same time to manufacture the probe. Then shrinkage which is caused at the time of the sintering is made uniform in the probe to suppress local curvature and strain, and the simultaneous sintering is performed, so no residual stress is left in the probe. Thus, tolerance to heat stress is obtained to obtain the probe with superior corrosion resistance.

Title: Magnetic recording/reproducing method, magnetic recording medium and magnetic recording/reproducing device
Inventor: ISHIDA MASAYA
IPC: G11B9/14
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To stabilize recording/reproducing operation over a long period while realizing magnetic recording of high density. SOLUTION: The magnetic recording/reproducing method reproduces information by allowing current to flow into a route including the probe and a recording medium 10 and utilizing the change in the electric resistance of the route which is generated in accordance with a difference in the magnetized state of the medium 10. In the method, it is preferable to allow current to flow into the route by bringing a tapered conductive probe close to the medium 10. At the time of recording information, it is preferable to execute thermomagnetic recording by allowing current higher than that in reproducing to flow into the route and impressing a magnetic field to the medium 10.  Information is reproduced preferably by using the change of electric resistance generated due to a relative angular change in the magnetization of each magnetic layer of the recording medium 10 having at least two magnetic layers on both sides through a non- magnetic layer 15. It is also preferable to reproduce information while impressing a magnetic flux and to impress the magnetic flux by a permanent magnet.

Inventor: SHIINA MITSUO
IPC: H01H25/00
Filed: 1994-03-24
Abstract: PURPOSE:To surely, stably conduct a large number of mode changes by forming a mode setting switch in a plural-directional sliding method. CONSTITUTION:When a slide switch is switched on in one mode PLAY, a slide key 13 is slid from a neutral position to the PLAY direction. By this sliding, a foot 41 of the slide key 13 slides a first spring 11 in the direction of an opening 15a along an opening 36 of a second spring member 12. By this sliding, a switch piece 28 of a switch 4a is also slid, and switched on in a mode PLAY. When a finger is detached from a key 13 after the mode PLAY was turned on, the key 13 is returned to the neutral position by the spring action of the spring 11. When the PLAY condition is stopped, the key 13 is slid in the direction of a mode STOP. When a mode is switched to REW, the key 13 is slid in the direction of REW. Similarly, by sliding the key 13 in the direction of FF, a mode is switched to FF.

Title: Receiving circuit
Inventor: KAWAI MASANORI
IPC: H04L27/14
Filed: 1993-03-15
Abstract: PURPOSE:To provide the receiving circuit which does not lower sensitivity even in the case of digital data communication. CONSTITUTION:A frequency side corresponding to data '1' is extended on a high frequency side and the band is enlarged in the frequency characteristics of filter matching circuits 5a and 5b arranged in the preceding stage and the rear stage of an intermediate frequency(IF) filter 2. Therefore, since the waveheight of a peak value in an impulse response is decreased for a base band signal obtained by delaying and detecting the passage of the IF filter 2 by a delay and detection part 4, an output level in a data signal is not considerably fluctuated and as a result, a pulse width is not enlarged.

Title: Phase difference plate
IPC: G02B5/30
Filed: 1992-03-13
Abstract: PURPOSE:To obtain an arbitrary refractive index and dependence on wavelengths and to obtain a sufficient optical compensation effect according to a change, if any in the optical characteristics of a liquid crystal display element by a temp. change by unidirectionally stretching a high-polymer film which is internally dispersed with liquid crystals thereby forming the phase difference plate. CONSTITUTION:The nematic liquid crystals 2 incorporated into the high-polymer film 1 are so oriented that there is no regularity in the orientation of the molecules, such as (A) before the stretching of the film 1 but that the molecules align uniformly along the stretching direction of the film 1 like (B) after the stretching of the film 1. The functions as the phase difference plates are, therefore, added to the film 1 and the internal crystals 2, respectively. Then, the refractive index and the dependence on the wavelengths are largely changed and the arbitrary characteristics are obtd. by selecting the respective materials of the film 1 and the crystals 2 and combining the characteristics thereof. The liquid crystals 2 in the film 1 have the dependence on temps. and, therefore, even if the optical characteristics of the element are changed by the change in the temp., the sufficient optical compensation effect meeting the change is obtd.

Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To detect frequency characteristics so that frequency characteristics to be recorded are changed into optimal frequencies, thereby resulting in a high image quality, that does not include deterioration in the image quality, inversion of white and black colors or the like, being stably obtained by recording and reproducing record signals of two or more different frequencies as means for detecting the frequency characteristics of a magnetic recording head and a magnetic tape. SOLUTION: A signal generating circuit 10 outputs a record signal while shifting its frequency from a reference toward higher frequencies. The record signal is amplified by a record amplification circuit 8, and recorded on a magnetic record tape 1 by A magnetic recording and reproducing head 2. A level calculation circuit 6 that receives the signal as its input via a reproduction amplification circuit 4 and a level detection circuit 5 compares the recorded and reproduced frequency characteristics with ideal frequency characteristics obtained from a memory circuit 7 to obtain a level difference. The level calculation circuit 6 allows a record equalizer circuit 9 to correct for the level difference to be closer to the ideal frequency characteristics.  Thus, any differences and changes over time in the characteristics of the magnetic recording tape 1 and the magnetic recording and reproducing head 2 can be corrected to realize improved characteristics.
