Title: Electromagnetic focusing cathode ray tube
Inventor: YOSHIMI ISAO
IPC: H01J29/68
Filed: 1980-07-02
Abstract: PURPOSE:To improve the deflection characteristic, convergence characteristic and the focus characteristic by providing a plurality of magnetic yokes in an electromagnetic focusing cathode ray tube. CONSTITUTION:There electrode sections or a cathode 2, first grid 3 and second grid 4 are arranged in a casing 1 while third grid bottom 5 and three pairs of magmetic yokes 6a, 6b, 6c, 6d and 6e, 6f are arranged while facing each other on same tube axis. Then a focusing permanent magnet 9 is arranged at the outside of said yokes 6c, 6d. Consequently the leakage field of the permanent magnet 9 is localized in the gaps 6g, 6e and 6f of each magnetic yoke to form the focusing field lenses 15a, 15b and 15c thus to improve the focus characteristic. While since the leakage field isn't produced at all at the cathode side and the phosphor face side of said yokes 6a, 6f the deterioration of the deflection characteristic and the convergence characteristic can be suppressed.

Title: Semiconductor device and manufacture thereof
Inventor: MORIWAKI SUSUMU
IPC: H01L29/78
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device in which an ohmic electrode is connected to a diffusion layer with a low resistance even if a silicide layer has been eliminated by over-etching. SOLUTION: Impurities are doped with a gate electrode 3 and a side wall insulating film 4 as masks, to form a source-drain diffusion layer 6. A titanium film 11 for forming a silicide layer is formed. Annealing is performed to cause Ti and Si to react to form a titanium silicide layer 7. An insulating film 8 is etched to form a hole 9. At this time, over-etching is performed with regard to the film thickness of the insulating film, to reliably eliminate the insulating film 4. At this time, the thin silicide layer 7 is also etched and eliminated from the bottom of the hole 9, thus a substrate 1 is exposed. A silicon film 15 is selectively grown on the substrate 1 exposed in the hole 9. A Ti film 11 is formed on the substrate 1 exposed in the hole 9, and an Al film is formed on the substrate 1 including that inside the hole 9.  The Al film and the Ti film 11 are patterned into an electrode/wire 10. Thus, junction leak current can be prevented.

Title: Picture signal detection circuit in optical transmission system
Inventor: AWAI HIROMITSU
IPC: H04B10/00
Filed: 1990-04-04
Abstract: PURPOSE:To surely suppress an output of a picture signal detection signal when optical signal transmission is interrupted by outputting an output of an integration circuit receiving an output of a horizontal synchronizing signal detection circuit as the picture signal detection signal. CONSTITUTION:An output of an A/D converter 7 connects to an integration circuit 8a via a horizontal synchronizing signal detection circuit 10. Thus, when a normal picture signal is not obtained due to interruption of an input optical signal or out of synchronization, a random noise is outputted from the A/D converter 7. Since the horizontal synchronizing signal detection circuit 10 cannot extract a horizontal synchronizing signal when a random signal in this way is received, no signal is outputted from the horizontal synchronizing signal detection circuit 10. Thus, no signal is inputted even to the integration circuit 8a and the picture signal detection signal is not outputted.

IPC: H05K3/06
Filed: 1988-04-12
Abstract: PURPOSE:To perform solder plating in an excellent state without concentration of electric charge in a long signal pattern, by forming a long, independent signal pattern on a wiring board, forming a dummy pattern in the vicinity of the signal pattern, and applying electric solder plating to both patterns. CONSTITUTION:One more pattern 3 is provided along an independent signal pattern in the vicinity (position without electric effect) of the long, independent signal pattern in a work film. The work film is exposed and developed. On this wiring board 1, copper is electrodeposited by several mum in a copper plating bath. Then solder is electrodeposited thereon by ten and several mum in a solder plating bath. Then, photoresist is removed, and etching is performed. The solder is separated, and a pattern is formed. In said electric solder plating, electric charge concentrated in the independent signal pattern 2 is dispersed to the dummy pattern 3. Therefore, the solder on the independent signal pattern is not burned. Thus, the excellent solder electrodeposition can be expected.

Filed: 1991-03-27
Abstract: PURPOSE:To achieve higher measuring accuracy with the simplification of operation by providing a pair of detecting sections in a heating furnace to determine specific heat by one measurement of material to be measured and a reference material. CONSTITUTION:Detecting sections 4 and 6 have sample trays 4a and 4b and 6a and 6b provided respectively with thermocouples 12a and 12b and 14a and 14b and the thermocouples detect the temperature difference of the sample trays.

The detecting section 6 has an empty cell 20 on the reference side 6a and a material 22 whose specific heat is to be determined on the sample side 6b. A sample is heated according to a specified heating program of a uniform-speed rise in temperature, and a temperature difference signal of thermocouples 12 and 14 is sent to a data processing section to calculate the specific heat of the material to be measured. Since the detecting section on the side of the material to be measured is connected to a balance, a change in weight during the measurement can be detected simultaneously to allow the correction of a change portion of the weight when the specific heat is calculated thereby achieving a higher measurement accuracy.

Title: Slack processing bobbin
Inventor: OTA MASATOMO
IPC: B65H75/14
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent rewinding by a simple structure and to ensure good workability in a slack processing bobbin. SOLUTION: A slack processing bobbin 10 can relatively move an opening and closing member 14 to a push-position and a pull-position by pushing in and pulling out the opening and closing member 14. When pulling-out or pushing- out force has no affect on the slack processing bobbin, the pushing-in position or the pulling-out position are maintained. When the opening and closing member 14 comes to the pull-out position, since a rewinding limiting piece 42 is retracted from flange members 16, 18, an optical fiber or a wire such as an electric wire is wound around a winding drum 20, or a wire wound around the drum can be rewound. When the opening and closing member 14 comes to the push-in position, since the rewinding limiting piece 42 traverses between the flange members 16, 18, the wire wound around the winding drum 20 can be prevented from being rewound. Thus, rewinding of the wire can be positively prevented by a simple structure, and the operation is simple and easy.
