Patent JP-H07121862-A (JP)
Title: Coating type magnetic recording medium
Inventor: KONDO HIROFUMI
IPC: G11B5/71
Filed: 1993-10-27
Abstract: PURPOSE:To enhance the wear resistance and durability of a magnetic head and a magnetic tape by holding an ascorbic ester compd. represented by a specified formula in or on the magnetic layer. CONSTITUTION:An ascorbic ester compd. represented by the formula is held in or on a magnetic layer. The ascorbic ester compd. is produced as follows; ascorbic acid and carboxylic acid are added to 95% concd. sulfuric acid and allowed to stand for a prescribed time, the resulting product is extracted with diethyl ether and washed until the soln. is made neutral, the soln. is evaporated and the product is purified by recrystallization from a diethyl ehter-hexane mixed soln. The number of alkyl groups in the carboxylic acid is preferably <=14 giving a low m.p. in the case of straight chains. Since the compd. represented by the formula is held in or on a magnetic layer, the brown staining and clogging of a magnetic head are suppressed and the durability of a magnetic tape is enhanced.

Title: Hot plate
Inventor: SOEDA SHINKO
IPC: H05B3/68
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To uniformly heat the contact surface of a work with a work adsorptive plate. SOLUTION: A work 10 is placed on a work mount plate made of a porous material, and evacuation is made by a vacuum pump connected with a suction hole 4b. The work 10 is sucked through micro-cavities in the porous material and adsorptively fixed to the adsorptive surface 3a uniformly. By a heater 1 a heating plate 2 is heated in the condition that the work 10 is attracted firmly, and the work 10 is heated uniformly. No distortion is given to the work 10 owing to a height plane accuracy of the work adsorptive surface 3a, and adsorptive attachment can be made without impairing the plane accuracy of the work 10. An appropriate countermeasure for the varying adsorptive attachment condition originating from the nature of the work 10 is, for example, to adjust the evacuation capacity of the vacuum pump or to change the grain diameter of the porous material.

Title: Manufacture of composite piezoelectric material film
Inventor: KURATA YASUYUKI
IPC: H01L41/45
Filed: 1987-10-27
Abstract: PURPOSE:To make the thickness of a piezoelectric body film thin and improve a piezoelectric constant, by coating a mixture in a slurry state where a piezoelectric elastomer, a conductive ceramic powder and carbon black are dissolved or dispersed in an organic solvent on a substrate with a screen printing technique. CONSTITUTION:A mixture in a slurry state consisting of: a piezoelectric elastomer, a piezoelectric ceramic powder, carbon black 3.5-4.0wt. part, and an organic solvent is coated in a film state to the prescribed thickness on a substrate with a technique of screen printing and its coating is finished by drying. In such a case, a zirconate titanate powder is used as the piezoelectric powder and it is desirable for its powder to have the average diameter 0.2-5mum of its particles.

Title: Echo cancelling method and echo canceller
Inventor: IMAI KENJI
IPC: H04B3/23
Filed: 1994-11-02
Abstract: PURPOSE: To attain proper cancelling at all times without any mistake in discrimination of a double talk and a single talk in any speech state. CONSTITUTION: When a slave set 2 starts talking a telephone line 3 via a master set 1, a CPU 15 sets a speech threshold level for telephone line decided in advance to an echo canceller 14 as an initial value. When a mean value of a difference between a transmission voice signal level detected by a level detection circuit 17a and a leaked voice signal level detected by a level detection circuit 17b is smaller than the speech threshold level set to the echo canceller 14 at present, it is highly possible that a double talk is mistaken as a single talk. Thus, the CPU 15 uses the mean value as the speech threshold level to set it to the echo canceller 14 repetitively as proper processing. Thus, discrimination between a double talk and a single talk is not mistaken in any speech state and proper cancellation is always attained.

Title: Password input device
Inventor: MIKI ISAMU
IPC: G06F19/00
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To prevent a password from being known by a third party even if the movement of an operator is observed by him. SOLUTION: This device is provided with a display/input device where a password input screen is displayed in the state that touch panels are piled up and specified information is inputted by touching the touch panel through an operator and a ten key control means for changing at random a position of each numeral key of a ten key 35 displayed on the password input screen. In this case, since the position of each numerical ten key 35 is changed at random, a third party cannot know the password even if he observes movement of the operator and a cash card of the operator is not abused.

Title: Sight position detection method
Inventor: NAKABA AKIRA
IPC: F41G3/26
Filed: 1989-10-17
Abstract: PURPOSE:To improve the accuracy of position detection by receiving the light of infrared beam generated from an infrared beam luminous instrument with a CCD camera mounted with a rack which can be arbitrarily controlled with regards to its orientation and inhibiting direction, and detecting its position based on the tip aimed at on a screen. CONSTITUTION:A target 2 to be aimed at is projected on an inner surface of a semi-sphere dome screen 1. A CCD camera 4 is mounted with this target projector 3. Then, the target 2 is arranged to exist constantly in the center of a camera image 8 by making the same motion with the target 2. At the same time, a visible radiation cut filter is mounted with the CCD camera so that only near infrared light may be received. When an attempt is made to sight the target 2 from an unspecified position within the semi-dome screen 1 with a collimator 6 mounted with an infrared luminous instrument 5, an infrared beam light 7 will appear within an image of the CCD camera 4. The image is binary-image processed so that the position in the camera image 8 may be specified. This construction makes it possible to minimize position errors as the distance up to the screen 1 is increased.

Title: Azimuth meter and true north measuring method
Inventor: SHINAGAWA YUICHI
IPC: G01C17/38
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To easily measure true north azimuth in an arbitrary area. SOLUTION: A GPS receiver 11 to detect a present position and an earth magnetism sensor 12 to detect a magnetic azimuth are provided in a computing part 13, positional information obtained by the GPS receiver 11 is substituted into the deviation distribution formula of an earth deviation model memorized by a memory part 14, in order to find a magnetic azimuth at the position, and a true north azimuth is computed by deducting the magnetic deviation obtained by the deviation distribution formula from the magnetic azimuth obtained by the earth magnetism sensor 12. The magnetic deviation at the present position is thus found by using the deviation distribution formula of the earth magnetism model, and the true north azimuth is computed by compensating the magnetic azimuth in accordance with the magnetic deviation.  Thereby, the true north azimuth can be very easily obtained, without requiring an expensive and large-scale appliance, and the true north can be indicated based on the true north azimuth.

Title: Frequency tuning circuit
Inventor: HAMADA YOSHIO
IPC: H04B1/26
Filed: 1984-12-21
Abstract: PURPOSE:To improve the frequency tuning accuracy of an output signal even when the accuracy of a fixed frequency oscillator is not so much high by adding a variable frequency oscillator and a frequency converter mixing an output signal of the fixed frequency oscillator. CONSTITUTION:An input signal fR is mixed with a variable frequency control signal fL from the 3rd frequency converter 3 by the 1st frequency converter 2. Then an output signal fIF1 from the 1st frequency converter 2 is mixed with an oscillated output signal fL2 from the fixed frequency oscillator 6 by the 2nd frequency converter 5 and the result is outputted to a signal output terminal 7. Thus, the output signal at the output terminal 7 is not immune to the effect of the oscillating output signal from the fixed frequency oscillator 5, that is, the effect of frequency fluctuation. Thus even when the accuracy of the fixed frequency oscillator is not so much high, the frequency tuning accuracy is improved.
