Title: Nd filter drive device, light quantity controller and image pickup device
Inventor: KANEDA NAOYA
IPC: G02B5/00
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To accomplish a light quantity control while considering prevention of shading on upper and lower parts by constituting an ND filter so that it may be provided with plural areas having different transmissivity and an area of high transmissivity may come into effective light first, in the case of coming into the effective light from outside the effective light. SOLUTION: ND filters having different density (transmissivity) are installed, that is, a filter 238 having comparatively low density (high transmissivity) and a filter 239 having comparatively high density (low transmissivity) are installed, and the filters are constituted so that they may be separatively provided with an area capable of completely covering the aperture diameter 205 of a diaphragm.  In this case, the density of one ND filter 238 is controlled so that the transmitted light quantity may be 1.5 steps (light quantity 1/2.8) in open aperture and the density of the other ND filter 239 is controlled so that the transmitted light quantity may be three steps (light quantity 1/8) in open aperture, then, the influence of the shading is drastically improved as compared with such the case that only the ND filter having the same density as that of the other ND filter 239 is put in/out the optical path.

IPC: G11B3/08
Filed: 1982-01-29
Abstract: PURPOSE:To move surely a tone arm vertically with simple mechanisms by providing a grooved lifter part in one body with a turning member which is turned in the stage of moving the tone arm vertically. CONSTITUTION:In the case of moving a tone arm upward, a turning member 9 turns at one end of a driving member, then the ridgeline 9C1 in the bottom part of a groove 9C abuts on the shaft 5 of a tone arm device 1; thereafter, the tone arm is moved upward by the ridgeline 9C1. Further, when the member 9 turns, the width of the groove 9C is narrower than the diameter of a shaft 5; therefore, the shaft 5 is sandwiched by the ridgeline 9C2 in the side part of the groove 9C. thus, in the stage of moving the tone arm upward with the ridgeline 9C1  in the bottom part of the groove 9C, a tracking error is corrected by the ridgeline 9C2 in the side part of the 9C even if said error arises in the tone arm.

Title: Recorder and reproducer
Inventor: NAKANO KENJI
IPC: G11B20/18
Filed: 1982-02-01
Abstract: PURPOSE:To attain correct reproduction at all times, by providing a prescribed dummy signal after and before a PCM signal and avoiding the generation of noise due to the demodulation of unerased remainder even if the unerased remainder takes place due to jitter. CONSTITUTION:As shown in figure A, a dummy signal of period of alpha each is provided after and before the PCM signal. The value of alpha is taken larger than the maximum value of fluctuation beta due to jitter. As the contents of the dummy signal, a signal not PCM-demodulated, e.g., PCM clock synchronizing signal is used. Thus, even if re-recording is performed under the jitter of beta as shown in figure B, the unerased remainder is the dummy signal only as shown in C and no hindrance is given to PCM demodulation. The dummy signal is formed at a PCM/time axis compression circuit 7.

Title: Driving method for multi-beam semiconductor laser for optical disk
Inventor: SUZUKI TOSHIHIRO
IPC: G11B7/125
Filed: 1989-01-24
Abstract: PURPOSE:To simplify and miniaturize an optical system of an optical head for an optical disk by driving a laser element which radiates the light of a shorter wavelength with the larger optical output and radiating the light of a waveform approximate to any laser element. CONSTITUTION:The resonance length of a laser element is decided by a breaking job due to the cleavage and therefore some variance is produced. In other words, the LD-1, LD-2 and LD-3 oscillate with the least wavelength lambda1, the medium wavelength lambda2, and the largest wavelength lambda3 respectively when these LDs are driven by the same optical output, e.g., P1. In this case, the LD-1 which oscillates a 3-beam semiconductor laser with the wavelength lambda1 is driven with the largest optical output P3. Then the LD-2 which oscillates with the wavelength lambda2 is driven with the medium optical output P2, and the LD-3 which oscillates with the wavelength lambda3 is driven with the least optical output P1. Thus these three laser elements LD-1 - LD-3 can be oscillated with an approximately equal wavelength lambda3. Thus an optical system is extremely simplified.

IPC: H03H3/08
Filed: 1979-02-14
Abstract: PURPOSE:To eliminate the difference between the actual and desired impulse replies which could not be avoided with the Campbell's method, by giving the right or left parallel shift to the opposing electrode edges. CONSTITUTION:Tooth parts 22 and 32 of the 1st and 2nd comb-line type electrodes which are adjacent to each other to secure the opposite potential are distributed with a slight right or left parallel shift given to their opposing electrode eges. As a result, the impluse reply sample value of ¦a2n¦>¦a2n+1¦ before the parallel shift is changed  to ¦a2n¦=¦a2n+1¦ after the shift. The same parallel shift operation is given among  all other split electrodes which are adjacent to one another to secure the opposite potential. And thus such split electrode distribution is secured for n as to satisfy a2n=-a2n+1. At the same time, the engagement width of the electrodes to be engaged is set to be 2Wn=2¦an¦, thus eliminating the difference of the impulse replies.

Filed: 1988-01-25
Abstract: PURPOSE:To keep safety even for a fault in a temperature signal input circuit by monitoring whether or not an energizing time on a load continues for more than a prescribed time by providing a timer circuit. CONSTITUTION:The timer circuit 7 is used for monitoring the time of the turn-on state of a control relay Ry1, etc., and the counting of an turn-on time is started from a time when the relay Ry1 is turned on by the circuit 7. When the energizing time on a heater H1 continues for more than the prescribed time, a processing different from an ordinary processing is started assuming the above fact as that the fault may happen in the temperature input circuit 3. In other words, temperature signals before and after are compared by stopping the energizing of the load for the prescribed time, and it is judged as normal when the temperature signal goes down, then, the processing is returned to the ordinary processing, and when it is judged that no change is observed, it is judged as that the fault is generated in the circuit 3, then, the energizing is stopped. In such a way, it is possible to detect the fault in the circuit 3 effectively, and to secure the safety.

Title: Optical scanning system having inclination correcting function using semicondutor laser
Inventor: OGURA YUKIO
IPC: H01S5/00
Filed: 1982-02-02
Abstract: PURPOSE:To make a titled system provided with an inclination correcting function, and also to shorten optical path length of the optical system, by placing a deflecting surface and a surface to be scanned, in conjugate relation, as to an image forming lens and a troidal lens, when a laser beam is deflected by a rotary polyhedral mirror. CONSTITUTION:A beam emitted from a semiconductor laser 1 is focused onto a deflecting surface 4 by a coupling lens 2. A cylindrical concave lens 3 has no refractive power on the surface in the sub-scanning direction, and there is no influence. The deflecting surface 4 is in conjugate relation geometrically to a surface to be scanned 7 as to an image forming lens 5 and a troidal lens 6, and it does not occur that a position of an image forming spot on the surface to be scanned 7 is influenced by inclination of the deflecting surface. In the main scanning direction, the beam emitted from the semiconductor laser 1 becomes an almost parallel luminous flux by the operation of the cylindrical concave lens 3, is made incident to the deflecting surface 4, and forms an image forming spot on the surface to be scanned 7 by th image forming lens 5 having an fTHETA characteristic. In this way, it is possible to form a spot of desired size on the surface to be scanned, by providing an inclination correcting function, and using a semiconductor laser having different light emitting size, in the orthogonal direction.
