IPC: G01V1/00
Filed: 1990-01-25
Abstract: PURPOSE:To easily distinguish earthquake wave from impact wave by putting mercury in a caved part formed in the center of a vibration plane and bringing it into contact with an electrode only at the time of vibration so as to detect the earthquake with a vibration of sensing apparatus. CONSTITUTION:An earthquake sensing apparatus 1 is prepared by putting mercury 2 in a caved part 4 formed in the center of a vibrating plane 3 and setting a circular electrode 6 while keeping a prescribed distance between the mercury 2 and the electrode. The vibrating plane 3 has a slight incline declining toward the center and normally the mercury 2 and the electrode 6 do not make contact with each other and only at the time of vibration, they make contact with each other.

The amount of the mercury 2 is set to be 0.4-0.5g and the depth of the caved part 4 is set to be 0.45-0.55mm and the bottom part is made smaller than an open part. The side walls 4c are made in taper shapes and the inner diameter of the bottom plane is set to be 2.5-3.0 and the distance between the mercury 2 and the electrode 6 is kept 0.5-1.5mm and the mercury is retained stably.

IPC: G11B7/24085
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To make a recording medium have satisfactory recording and reproducing characteristics to be strong against a medium noise and to be free from reduction of an information output even in an area of a high recording density, especially of a high linear recording density. SOLUTION: A reference track 2 where marks are recorded at equal intervals and an information track 1 which is adjacent to the reference track 2 and where plural mark columns 3 and 4 consisting of marks at equal intervals are formed are provided, and each of mark columns 3 and 4 of the information track bears the phase difference between marks of this mark column and those of the reference track adjacent to this mark column as information. Mark columns 3 and 4 of the information track 1 and marks of the reference track 2 adjacent to it are recorded at equal intervals so that reproduced signals of the same frequency can be obtained at the time of reproducing marks of two tracks and the phase difference between the phase of the information track reproduced signal and that of the reference track reproduced signal can be detected.  The number of marks included in a mark column of the information track corresponding to one information unit is arbitrary, but it is desirably <=15 because too many marks reduce the linear recording density.

Title: Parts feeder
Inventor: HARA NORIO
IPC: G01V8/24
Filed: 1978-02-14
Abstract: PURPOSE:To distinguish the attitude and form of small parts, by sending the reflected light from the objects being inspected or the light transmitted through the  objects being inspected into a photo detector consisting of photoelectric transducer  by way of an optical fiber. CONSTITUTION:When a part 6 moves onto an optical fiber fitting plate 8, the light to be transmitted is shielded by an optical fiber 7 to turn off a photoelectric transducer 9. The attitude of the part is sorted by presence or absence of this shielded light. In this device, multiple detectors may be installed in a small area, so that it is very effective when sorting the attitude of small parts having complicated form such as watch parts. The transducer 9 may be placed away from the detecting part, that is, a ball 1, and may also be installed in a free place together with an amplifier which should be placed near the transducer 9 from the viewpoint of reliability. Thus, impossibility of photo detection due to space limitations may be eliminated. Even if the form of part 6 is changed, the same ball may be used by providing multiple detecting points consisting of fiber 7 and transducer 9, simply by changing the logic circuit.

IPC: H05B41/18
Filed: 1988-01-27
Abstract: PURPOSE:To reduce the loss during the stationary lighting of a discharge lamp by by-passing a high voltage pulse generating circuit with a relay switch just after starting the discharge. CONSTITUTION:When a discharge starting switch 51 is switched on a capacitor 54 for generation of a primary high voltage is charged up, and when the charged voltage exceeds the break-over voltage of a thyristor 55, the capacitor 54 is discharged so as that the voltage is applied to a transformer 56 generating a primary high voltage pulse. Then the induced voltage is applied to a capacitor 60 through a rectifier 59. When the charged voltage of the capacitor 60 exceeds the break-over voltage of a spark gap 61, the discharge current of the said capacitor is flowed in a transformer 39 generating a secondary high voltage pulse to light a discharge lamp 34. When the discharge is started as described above, the thyristor 55 is cut off and the generation of the high voltage pulse is stopped. Then a Zener diode 44 is cut off by the voltage drop in a stabilizer coil 38 for current control and a relay coil 45 is demagnetized to switch on a relay switch 47. Therefore the loss during the stationary lighting of the lamp can be reduced.
