Title: Laminated capacitor
Inventor: YABUUCHI SHOZO
IPC: H01G4/30
Filed: 1987-07-10
Abstract: PURPOSE:To prevent the generation of microcracks and to improve reliability of a capacitor, by forming lower electrode layers of a metal containing Pd on the opposite end faces of a laminate consisting of ceramic layers so that the external electrodes are diffused to the lower electrode layers. CONSTITUTION:Ceramic bases 2 and internal electrodes 3 consisting of a metal containing palladium are laminated alternately. The electrodes 3 are extracted altrenately to the right-hand and left-hand sides of the laminate where they are electrically connected with external electrodes 5 consisting of a metal containing silver. The external electrodes 5 are formed on lower electrode layers 4 which are formed of a metal containing palladium on the right-hand and left-hand end faces of the laminate, and integrally with the electrodes 3. Since the electrode layers 4 are contacted with the electrodes 5, the electrodes 5 are first diffused into the electrode layers 4. Accordingly, the electrodes 5 are inhibited from directly entering into the electrodes 3 while outstretching the upper and lower ceramic layers 2. In this manner, it is made possible to prevent the generation of microcracks and the laminate capacitor thus obtained is allowed to have improved reliability.

Title: Manufacture of magnetic head
Inventor: SATOMI MITSUO
IPC: G11B5/187
Filed: 1984-08-21
Abstract: PURPOSE:To manufacture a magnetic head having excellent touch with a tape and stable output and long life by forming a notch to a base near the head gap in the direction of gap depth to reduce partially the tickness of a chip. CONSTITUTION:An amorphous alloy 11 is formed by sputtering on a photosensitive glass substrate 10, a laser beam is irradiated on the substrator 10 near a gap 12 of a magnetic head in the direction of gap depth to form a notch A. In this case, the nearest distance to the amorphous alloy 11 is processed in 10mum at the apex of the notched triangle form. Similarly, a head processed with notches of shapes B, C is formed. The head output having a wider notch area than that of the shape A is made stable and the head with the shape B has excellent wear resistance. Thus, the head provided with the notches near the gap to decrease the head chip width, with long service life and stable output and excellent touch with a tape is manufactured in this way.

Abstract: PURPOSE:To deal with the results of adjustments between controllers and to improve operability by making it possible to use the setting conditions by a proximity controller or remote controller by both controllers. CONSTITUTION:A changeover switch 6 is selected to a cassette side and diaphragm vanes 9 are moved to meet the size of a cassette by a diaphragm controller 5 of the proximity controller 4 in order to execute cassette photographing. The proximity controller 4 is used and the photographing is started by a photographing switch 8 in the case of not changeover to the remote controller 2. The data on the diaphragm size of the diaphragm vanes set by the proximity controller 4 is inputted to the remote controller 2 and the photographing is started by the photographing switch 8 of the remote controller 2 when the changeover switch 7 is changed over to the remote controller 2 side in the case of changeover to the remote controller 2. Namely, the deviation of the diaphragm vanes 9 generated by changing over of the controllers is eliminated and the smooth photographing is made by inputting the data on the diaphragm size in the proximity controller 4 to the remote controller 2.

Abstract: PURPOSE:To attain cost reduction, by providing a manuscript density detection sensor at a position oblique to a partial light emitting filament and providing a small hole at the position of a reflective plate linearily connecting the manuscript density detection sensor and the partial light emitting filament. CONSTITUTION:The light from a halogen lamp 1 is condensed to and reflected from a reflective plate 4 and the manuscript 2 on contact glass 3 is exposed to and illuminated by the reflected light.

A small hole 4a is formed to the reflective plate 4 at the position on the straight line connecting the light emitting part of the lamp 1 and the sensor 8 and manuscript irradiating light can be guided through the small hole 4a as shown by a broken line. By this mechanism, the sensor 8 is separated from the light emitting part and the effect of temp. imparted to the manuscript density detecting surface can be reduced.

Title: Semiconductor device
Inventor: ISOBE MITSUO
IPC: H01L27/02
Filed: 1984-08-21
Abstract: PURPOSE:To prevent the breakdown of an insulating film from surge voltage applied from the outside by forming an insulated gate type transistor, a gate thereof is set at predetermined potential, to an external connecting terminal for a semiconductor device with the insulating film and protecting the breakdown of the insulating film by the transistor. CONSTITUTION:Power supply terminals 31, 33 are not supplied with power supply yet and are brought to ground potential on a manufacturing process or handling. When surge voltage is applied to an input terminal 15 under the state, a P channel MOS transistor 32 is turned ON to positive surge voltage while a P-N junction in a drain in the transistor 32 is directed in the forward direction, and currents flow. An N channel MOS transistor 34 is turned ON to negative surge voltage while a P-N junction in a drain in the transistor 34 is directed in the forward direction, thus flowing currents. Accordingly, currents flow through the MOS transistors 32, 34 even when surge voltage is applied to the input terminal 15, thus applying no high voltage to a gate G for a MOS transistor 12.

Title: Alarm device
Inventor: IWASHIGE NOBUO
IPC: G08B25/10
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To detect automatically a SART(Search And Rescue Transponder) signal and to aim speed-up of lifesaving, by executing correlative processing between a modulation component in a SART radio wave and a reference signal, and by separating from mixed radar reflected waves. SOLUTION: A signal processing device 2 inputs a received signal of a radar device 1, and a gate circuit 21 opens a gate. If an open time is a counting time equivalent to an IF bandwidth of the radar device 1, a counting circuit 22 sends the signal to a correlation circuit 23 and a gate control circuit 24. The gate control circuit 24 opens the gate by the signal as long as a time equal to the counting time at an arrival predicted time of the next SART signal, to put it into the waiting reception state. If a first reception signal is a SART signal, the signal is received at the next waiting time, and if there is no reception, the system is reset to return to the waiting state in the beginning. The correlation circuit 23 obtains correlation between the SART signal and a reference signal of a reference signal generator 26, and an averaging circuit 25 averages the result.  If a mean value in a unit time is a prescribed value or more, the reception is judged finally as a SART signal reception and an alarm display device 3 is operated.

Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a winding excellent in heat resistance, ease for winding as an electric apparatus coil, and a coil space factor characteristic by forming a self-lubricating enamel coating layer on the upper surface of a inorganic insulating layer formed on a conductor. SOLUTION: It is preferable that an inorganic insulating layer is formed from a polycarbosilane resin, a silicone resin and inorganic filler powder, and a self-lubricating enamel coating layer is a self-lubricating polyamide resin layer. This winding is provided with a nickel plated layer 2, the inorganic insulating layer 3 and the self-lubricating enamel coating layer 4 on a copper conductor 1 in that order. When a self-lubricating property is imparted to a general-purpose enameled wire paint, a minute quantity of polyolefin, fatty acid ester, wax, fluorine resin fine powder, or a silicone resin is mixed.  The inorganic winding has a surface friction factor lower than that of the self- lubricating enamel coating layer, thereby allows the thickness of the self- lubricating enamel coating layer to be reduced, and exerts remarkable ease for winding as a coil and a high coil space factor characteristic without increasing its outside diameter.
