Title: Optoelectrical analog time indicator
Inventor: NIRAI KUMAARU
IPC: G04G9/02
Filed: 1981-02-18
Abstract: The device displays an hour hand and a minute hand on a twelve hour dial and comprises a layer of electro-optical material having on one face an inner ring of 10 sectorial plate electrodes B1 etc, each subtending an angle of 36 DEG  and a corresponding outer ring of 10 plate electrodes B11 etc. On the other face there are sixty radial segments electrodes arranged in ten groups of six segments. Each group is opposed to a respective one of the ten plates. The segments are connected in six meandering circuits M1 to M6 so that, in proceeding one way round the dial, the segments of the said groups pertaining to the circuits M1 to M6 and then to the circuits M6 to M1 and so on in alternation round the dial. As can be seen from the steady lines demarcating the plate electrodes, these electrodes are assymetrical relative to the 12 o'clock axis of the dial so that there is a boundary between two adjacent plates in each ring angularly offset from that axis by a whole number of the segments, namely one segment as illustrated.

Title: Solder precoated circuit board
Inventor: HIKASA KAZUTO
IPC: H05K1/11
Filed: 1993-01-18
Abstract: PURPOSE:To allow highly reliable component mounting by permitting the shape of a pad to have a wide part in the longitudinal direction. CONSTITUTION:The expressions I and II are satisfied, when L2 is the length of the wide part 2a of a pad 2, (x1, y1) is the center position of 2a, F is the length of the flat part of the lead 4 of a component to be mounted and (x2, y2) is the center position of the flat part. The expression I is the condition that positions the center in the lengthwide direction of the pad wide part 2a within a range of the length of the flat part of the lead 4, and such condition allows sure contact of the summit of a solder top 3a with the flat part of the component lead 4. The expression II is the condition that allows the length of the pad wide part 2a to be longer than the length of the flat part of the component lead 4 by 0.1-0.3mm, and the condition allows the formation of a solder fillet suitable for the top and the heel of the component lead 4. Thus highly reliable component mounting is allowed.

Title: Image forming device
Inventor: INAMI SATOSHI
IPC: G03G15/02
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To prevent a faulty image such as horizontal stripes from occurring by neutralizing a surface potential of an image carrier by applying only an alternating voltage to the image carrier, and damping the applied alternating voltage down to OFF after the rotary drive of the image carrier is halted. SOLUTION: A sine wave is generated in either one or the other polarity as a fundamental waveform 20 and is amplified to a prescribed current or a voltage by an amplifier circuit 22 by making it flow through a capacitor 21 to cut off a DC component. On the other hand, a current signal 26, which is a reference of a charging AC voltage, is sent from a control circuit of the image forming device. A signal 28 is compared with a signal 29 by a comparator circuit 23, and is amplified by the amplifier circuit 22 and is not outputted until it becomes equal to the reference current signal 28. When the signal 26 is turned OFF here, the signal 28 becomes a damping signal with respect to time. Therefore, the output 27 shows a waveform of gradually damping the charged AC voltage.  And, after the rotary drive of a photoreceptor drum is stopped at the end of backward rotary operation, the applied AC voltage for AC neutralization is damped down to OFF.

Title: Fire-detecting apparatus
Inventor: SUZUKI MIKI
IPC: G01J1/42
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a fire detection apparatus which prevents a wrong report of a fire, can simply set a threshold value for a fire judgment, and correctly detect a position of the fire. SOLUTION: The apparatus employs a group of pyroelectric thin film heat detection elements. A plurality of sensors 1a, 1b having two-dimensional infrared detection view fields are used and arranged so that the detection view fields overlap. A position of a source of a fire generated in an overlapping view field is three-dimensionally detected by a position operation part 8 from a heat image detected by each sensor 1a, 1b and a distance between the sensors. A distance from the position of the fire source to the sensor 1a, 1b can thus be detected. An infrared detection signal is corrected with the distance taken into consideration. A correct fire temperature is calculated, so that a large heat source at a near distance and a small fire at a far distance can be distinguished from each other and a wrong report can be prevented.

Abstract: PURPOSE:To improve the operability of a position detecting device and to detect accurately the position of a magnetic field generator for designation of position, by making use of the variation of the permeability of a magnetic material to detect the position of said magnetic field generator. CONSTITUTION:A position detecting part 10 contains long magnetic materials 11a-11h arranged in parallel with each other and coils 12a-12h wound round the matters 11a-11h respectively. Now a magnetic field generator 20 for designation of position is set above matters 11a-11h. Under such conditions, the coil of the magnetic material set closest to the position of the generator 20 has the minimum inductance. Then the inductance is increased gradually toward the opposite side to the coil closest to the generator 20. Here the inductances of coils 12a-12h are converted into electric signals by a converting circuit 30 and a signal selecting circuit 40 and then undergo the arithmetic processing through a position detecting circuit 50. Thus the position of the generator 20 is detected. As a result, the operability is improved with a position detector and also the position detecting accuracy is improved.
