Title: Optical pickup device
Inventor: HATANO HIDEKI
IPC: G11B7/135
Filed: 1987-04-08
Abstract: PURPOSE:To stabilize S/N of an optical pickup device, by forming a single longitudinal mode and multiple longitudinal mode semiconductor lasers unitedly and using the former for recording and latter for reproducing, and then, making the output of the former coincident with the optical axis of an object lens and inclining that of the latter against the optical axis. CONSTITUTION:Two semiconductor lasers, one of which is single longitudinal mode type one and the other of which is multiple longitudinal mode type one, are united and the former is used for recording and latter for reproducing. The light 14 outputted from the single longitudinal mode semiconductor laser is made incident to an object lens, with the incident angle being almost coincident with the optical axis 12 of the lens. The light 13 outputted from the other laser is made incident to the object lens, with its incident angle being inclined against the optical axis 12 by a prescribed angle. Therefore, the quantity of the return light of the light 13 tends to change, but the light is hardly affected by the returning light because the laser is multiple longitudinal mode type one. The light 14 is apt to be affected by the return light, but fluctuation of the return light quantity caused by the position of this pickup, etc., hardly occurs. Therefore, information can be recorded and reproduced with stable S/N.

Title: Generator for time axis error signal of reproduced signal
Inventor: KURODA KAZUO
IPC: H04N9/455
Filed: 1983-05-17
Abstract: PURPOSE:To detect a specific point in the waveform of a reproduced color burst signal at an optimum position by providing a means which resets the level of a control signal for the generation timing of a timing signal for the generation of a time axis error signal. CONSTITUTION:When a reproduced composite video signal (a) is supplied to a burst gate 1, a monostable multivibrator 8 is triggered. At this time, the inversion time of the monostable multivibrator 8 is so determined that it is reset to a high level further in front of a position Y which is one cycle before the optimum detection position X of the specific point on the color burst signal waveform. When, however, a vertical synchronizing signal is reproduced, a capacitor C1 is discharged by the operation of a resetting circuit 22 during annihilation and a control voltage (k) is reset to a zero level, so the inversion time of the monostable multivibrator 8 becomes longer, so that the vibrator is reset to the high level within one cycle before the optimum detection position X. Consequently, the specific point is detected at the optimum position X.

Inventor: YOSHIZAWA MASAOMI
IPC: B65D41/04
Filed: 1989-04-07
Abstract: PURPOSE:To allow adjusting the torque for opening a cap mounted on a mouth by a method wherein a chamfer is formed at the inside corner of a top open end of a mouth so as to adjust the area of a cap sealing material in contact with the top open end. CONSTITUTION:A chamfer 9 is formed at the inside corner of an open end 3 of a mouth 2 to adjust the area of the open end in contact with a cap sealing material 8 when a cap 6 is screwed on the mouth 2, so that the torque for opening the cap for the first time is adjusted. That is, the area of the open end is reduced as a larger chamfer is formed, and the compression stress on the area of the cap seal material in contact with the open end increases, which is produced corresponding to the compression load from the open end 3 when the cap 6 is screwed on the mouth 2. On the other hand, the compression stress on the area of the cap seal material 8 in contact with the open end 3 is not increased so much with a little chamfer. Therefore, the torque for opening the cap 6 is adjusted corresponding to the size of the chamfer 9 formed on the open end 3.

Title: Level detecting circuit
Inventor: HASHIMOTO MASARU
IPC: H03G11/06
Filed: 1983-05-18
Abstract: PURPOSE:To reduce the area occupied by a chip and to enable measurement over a wide frequency range without requiring coupled capacity by using a differential transistor pair for an amplitude limiting amplifier voltage and a biasing voltage. CONSTITUTION:The amplitude limiting amplifier voltage generated by the full wave rectification of the input signal by a differential amplifier 21 forming an amplitude limiting amplifier circuit is impressed on the base of an npn transistor Q3 of a level detecting circuit 25. On the other hand, a biasing voltage is impressed on the base of an npn transistor Q4 forming a differential paired transistor together with the TRQ3 by emitter coupling. Thus, the TRQ3 turns on only in the input period when the base voltage is above the base voltage of the TRQ4 then the DC level of the amplitude limiting amplified output is detected with the collector of the TRQ3. The area occupied by the chip is reduced by such costitution requiring no coupled capacity and the detection over a wide frequency range is made possible.
