Title: Device for discriminating digital reproduction signal
Inventor: URAKAWA YOSHIYUKI
IPC: G11B5/09
Filed: 1992-03-16
Abstract: PURPOSE:To facilitate digitization by deciding whether digital reproduction signal has positive or negative peak value and maintaining the threshold level between the positive and negative peak values. CONSTITUTION:Since the digital reproduction signal is not inputted when the power supply is turned on, noise signal is inputted to an A/D convertor 10. Consequently the threshold level th is in the middle of '1' and '0'. After inputting the digital reproduction signals, since the threshold level th has the middle value before the digital reproduction signal is inputted, the threshold level is shifted smoothly to the threshold level corresponding to the swell of the digital reproduction signals. Thus, the processing just after inputting the digital reproduction signal is not especially required.

Title: Manufacture of shadow mask
Inventor: TANAKA YUTAKA
IPC: H01J9/14
Filed: 1991-02-28
Abstract: PURPOSE:To restrain production of bubbles in applying a corrosion resistant layer so as to reduce generation of a deformed through hole by making a surface of a small hole less than specific average roughness. CONSTITUTION:Resist films 33a, 33b having large hole patterns and small hole patterns are formed on both surfaces of a plate-like shadow mask material 30. A small hole 36b is formed by etching one surface. The surface of the small hole is formed into a flat surface having average roughness of 0.40mum or less so that bubbles cannot be generated in an interface in the case where a corrosion resistant layer is formed at the inner surface of the small hole. Consequently, it is possible to prevent generation of a deformed through hole due to the bubbles. After the formation of the corrosion resistant layer in the small hole, a large hole 36a communicated with the small hole is formed by etching a shadow mask material at the other surface, thus obtaining a shadow mask.

Title: Antenna system
Inventor: IGUCHI AKIHIKO
IPC: H01Q13/08
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a compact antenna system in which the degree of freedom of impedance matching can be increased, and the matching can be easily realized by providing irregularities at the radiating conductor element of a plate-shaped antenna. SOLUTION: The irregularities are formed at the radiating conductor element of a plate-shaped antenna. This device is constituted of a radiating conductor element 10 including the irregularities 11, a ground plate 12 arranged at a position faced to this element, short-circuit terminals 13 for short circuiting the radiating conductor element 10 and the ground plate 12, a power feeding terminal 14, a reactance element 15, a second short-circuit element 16, a spacer 17, and a dielectric 18 inserted into the irregularities 11. In this device, the surrounding length of the radiating conductor element 10 constituted of the irregularities 11 is made longer than an element constituted of a flat plate so that transmission and reception can be realized with low frequencies.  As a result, in the case of operating transmission and reception with certain frequencies, the radiating conductor element 10 can be made more compact that the conductor element constituted of the flat plate. Also, the size, position, and number of the irregularities 11 is changed so that the impedance can be changed. Thus, the irregularities 11 can be used for the impedance matching.

Title: Optical fiber
Inventor: NAKAGOME SEIJI
IPC: G02B6/00
Filed: 1990-03-09
Abstract: PURPOSE:To prevent stress from being concentrated on a connection part by increasing the thickness of the jacket material outside a terminal part connected to an optical connector gradually toward the terminal side. CONSTITUTION:The thickness of the jacket material outside the terminal part 3 connected to the optical connector 2 is increased gradually toward the terminal side. The thickness is increased toward the terminal side continuously in general, but can be increased intermittently. The outside jacket material can avoid the stress concentration on a tapered part made of a rubber elastic body or soft resin and even when the optical fiber is connected to the hard material part of the optical connector, etc., the optical fiber is never folded. Consequently, the stress concentration on a joint part can be precluded.

Title: End-face cutting device for packed roll
Inventor: KASAHARA TAKAHIRO
IPC: B65B69/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To cut off surely the end-face packing material of a packed roll without damaging the end face of main paper. SOLUTION: The device presses a knife 3 against the end-face packing material 2 of a packed roll 1 and rotates the packed roll 1, thereby thrusting the knife 3 through the inside of the end-face packing material 2, and then cuts a peripheral-face packing material 4 with the knife 3 in a circumferential direction. In the device, when the knife 3 is thrust through the end-face packing material 2, the angle of the knife 3 to the end face of the packed roll is the angle at which a blade 3a is satisfactorily thrust through the end-face packing material 2.  After the knife 3 is thrust through the inside of the end-face packing material 2, the angle of the knife 3 is altered to obtain a direction in which the blade 3a is moved apart from the end face of main paper, thereby satisfactorily cutting only the peripheral-face packing material 4 without the knife 3 being thrust through the end face of the main paper.

Title: Manufacture of magnetic bubble memory element
Inventor: HIROSHIMA MINORU
IPC: G11C11/14
Filed: 1986-03-19
Abstract: PURPOSE:To improve magnetic bubble transfer characteristics by implanting ions after adhering a passivation film onto a magnetic bubble magnetic film. CONSTITUTION:A mask MSK for ion implantation which is made of a thin film pattern such as a heat-resisting resin (e.g. polyimide resin) film and a thin gold film is formed on the magnetic bubble magnetic film LPE corresponding to an area (ion unimplanted area) where no ion is implanted. Then, ions I<+> such as H2<+>, He<+>, Ne<+>, etc., are implanted into the surface of the magnetic bubble magnetic film LPE and thus the ions I<+> are implanted in an area other than the area where the mask MSK is formed to form an ion implanted layer ION and also form an ion implantation transfer pattern IPT in the area where the mask MSK is formed. When H2<+> is used instead of I<+>, a spacer film SP such as an SiO2 thin film is formed on the surface immediately after the ion implantation to prevent the implanted ions I<+> from being vaporized away in subsequent processes.
