Title: Remote control type automatic floating-stop float
Inventor: SUDA SHIGEO
IPC: A01K91/06
Filed: 1995-03-06
Abstract: PURPOSE: To eliminate floating-stop operations or trouble due to contact with a top guide and provide many fishermen with the pleasure of fishing a black porgy by drop-in fishing. CONSTITUTION: This automatic floating-stop float is obtained by installing a guide pit 2 and a receiving switch 4 in the interior of a float 1, attaching a rubber tube 3, magnets 5 and 6 and a rubber-covered wire 7 to the interior of the guide pit 2 and further providing a transmitter and a transmitting switch. When the transmitting switch attached to a rod is operated, the receiving switch 4 is operated to rotate the magnet 5 by 180 deg.. The magnets 5 and 6 are mutually attracted by a change in magnetic poles to attract the rubber-covered wire 7. Thereby, the rubber tube 3 is deformed to tighten a main line 14 in the interior thereof and the lowering into the sea is prevented. When the transmitting switch 4 is operated, the rubber tube 3 is returned to the original state and the main line 41 is relowered into the sea.

Title: Piezoelectric element
Inventor: HASE KIYOSHI
IPC: H03H9/02
Filed: 1992-04-13
Abstract: PURPOSE:To reduce a change in a piezoelectric characteristic due to the heating cooling operation by using a piezoelectric ceramic whose CR product is a specific value or below so as to form the piezoelectric element thereby quickly discharging a pyroelectric charge generated even under the environment applied with the heating cooling processing. CONSTITUTION:A piezoelectric ceramic 4 whose CR product being a product of a static capacitance and an insulation resistance is 0.1-100F.OMEGA is used. That is, the piezoelectric ceramic 4 whose time constant tau is 100sec or below is employed. Thus, the pyroelectric charge generated after heating and restoration to room temperature is quickly discharged. Thus, an electric field in the opposite direction to the polarization direction due to the pyroelectric charge is not applied to the piezoelectric ceramic 4 for a long time. Thus, the decrease in the residual polarization is suppressed and fluctuation in the resonance frequency and the anti-resonance frequency is reduced. Furthermore, when the CR product exceeds 100 F.OMEGA, the discharge of the pyroelectric charge slows down and the deterioration in the characteristic of the piezoelectric element 3 due to heating/cooling is increased. When the CR product is less than 0.1F.OMEGA, the resistance of the piezoelectric ceramic 4 is too low and the polarization processing is not actually implemented.

Title: Quality inspecting method of magnetic recording medium
Inventor: SUGIZAKI TSUTOMU
IPC: G11B33/10
Filed: 1980-07-07
Abstract: PURPOSE:To ensure a quantitative detection for the defect of quality on the surface and inside a magnetic recording medium in terms of the size, form, position and other factors, by displaying or recording the envelope curve pattern obtained from a reproduction head in correspondence to the 2-dimensional position on the recording surface. CONSTITUTION:The signal of sine wave or the like recorded nearly an entire region of a recording medium through a recording/reproducing device 1 is obtained by a magnetic head that shifts in a desired direction. The envelope curve is obtained from the corresponding reproduced signal through an envelope wave detector 2 and then receives an A/D conversion by an A/D converter 3. Then the above-mentioned reproduced signal is selectively stored in a digital memory means 5 by an amount equivalent to a filed by the synchronous signal which is required for a TV system. After this, the output signal of the memory 5 is converted into an analog signal through a D/A converter 6. The synchronous signal necessary for the TV system is added to be displayed on the screen of a TV7 or to receive a hard copy.

Title: Image processor, print system, identification information imbedding method, identification information read method and storage medium recording program
Inventor: OTSUKA SHUJI
IPC: B41J29/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To attain reading, while minimizing deterioration in image quality by applying a modulation using a prescribed frequency to display-parameters in any direction on an image to imbed a pattern representing identification information into the image. SOLUTION: A background image (a), expressing mountain range with blue sky as their background that is an object image, to which identification information is to be imbedded, is received. The identification information (b) with a pattern similar to that of an alphabet 'E' that is the identification information to be imbedded to the background image (a) is generated. Imbedding this pattern into the image (a) forms an image (c). In this case, a modulation method is used to imbed the identification information to the image. That is, the blue sky part of the background image (a) has a higher luminance and the mountains part has a lower luminance. Then a modulation (perturbation) with a prescribed frequency is applied to the substantial luminance to imbed the identification information into the background image (a).  Thus, the modulation with the prescribed frequency is applied to the luminance in any direction on the image, so as to imbed the pattern representing the identification information into the background image (a).

Title: Communication control system
Inventor: GOTOU TAKESHI
IPC: H04J99/00
Filed: 1984-05-10
Abstract: PURPOSE:To attain the sound communication without using any new sound circuit (interphone circuit, etc.) nor producing mutual noises, by superposing a sound signal on a communication circuit using a bear cable. CONSTITUTION:The data signal and the sound signal on a transmission line are transmitted between lines 1 and 2-1 and 2-2 as a differential signal and an in- phase signal respectively. Then LPF3-1 and 3-2 which transmit only the data signal of a base band and delete the sound signal are put between a communication module 5 and communication circuits 1 and 2-1-2-2 respectively since it is sometimes considered that the sond signal is not delected completely owing to th delay caused by the variance of the impendance or the capacity on the circuit. When the sound signal is transmitted, the modulation is applied to the sound signal with a carrier of several 100kHz in order to avoid the superposition between the sound signal and the data signal of the base band.
