Patent JP-S59230372-A (JP)
Title: Dynamic focus circuit
Inventor: YOSHIOKA MAKOTO
IPC: H04N3/26
Filed: 1983-06-13
Abstract: PURPOSE:To obtain a focus voltage having a sufficient peak voltage by making the peak of a sinusoidal wave voltage produced by the series resonance in response to a flyback pulse coincident with the timing of the flyback pulse. CONSTITUTION:The flyback pulse extracted from an intermediate tap of a flyback pulse transformer 5 is applied to a series resonance circuit comprising a capacitor 7 and a coil 6. The current flowing to this resonance circuit becomes a sinusoidal waveform delayed by pi/2 from the flyback pulse and a voltage waveform between terminals of the coil 6 becomes a sinusoidal waveform lead by pi/2. Thus, since the flyback pulse is applied to this voltage waveform at a point B, this waveform has a peak voltage of >=200V, and this result is effective as the focus voltage of a CRT4.

Title: Light input integrated circuit
Inventor: OONISHI NORIYASU
IPC: H01L21/60
Filed: 1988-04-27
Abstract: PURPOSE:To obtain a semiconductor device with few erroneous operations due to external rays of light at a low cost, by providing a metallic layer to a bonding pad so that the leakage of light from the periphery of the bonding pad is intercepted. CONSTITUTION:The third metallic layer 10 is formed on a bonding pad 2 as well as on an insulating layer 5 for protection so that a part which is not intercepted by a metallic layer 6 for shielding the light can be intercepted. Since a light having the direction almost horizontal is intercepted by the third metallic layer 10 from a vertical direction with respect to the chip surface of an external light 8, the circuit operation of this device is not affected by the external light and no erroneous operations are induced by the external light. Further, the components which intercept the light at the outside can be omitted; besides, the need for separating the bonding pad from a circuit part is eliminated as well and thus a compact chip size is obtained at a low cost.

Title: Bias magnetic field generating device
Inventor: MIZUNO OSAMU
IPC: G11B11/10
Filed: 1986-05-12
Abstract: PURPOSE:To uniformize the distribution of magnetic field intensity, by forming the magnetic cavity width of a magnetic cavity part as narrowest at a part where it locates at the midpoint in the access range of an optical head, and expanding the width as it goes away from the part at the midpoint along the access direction of the optical head. CONSTITUTION:By permitting a current to flow on a driving coil 12, a magnetic flux is supplied on the recording surface of a magneto-optical recording medium, but a magnetic cavity width Lg on the medium facing plane of a bias magnetic field generating device, is narrow in the center of the bias magnetic field generating device, and is expanded as it goes away from the center, therefore, a component in a direction to separate from the center out of components of the magnetic field in arrow head A direction is reduced as it approaches to an end part. Therefore, the magnetic field intensity obtained on the recording surface of the magneto-optical recording medium is not increased at end parts P and Q in the access range of the optical head, and the intensity becomes the same level as the one of point O at a center part. In this way, the magnetic field intensity on the recording surface of the medium can be uniformized against the optional access position of the optical head.
