Title: Optical head and its signal detecting means
Inventor: TAKEDA TAKASHI
IPC: G11B7/09
Filed: 1991-09-09
Abstract: PURPOSE:To execute a signal processing of a high band by decreasing the floating capacity by performing non-reflective coating to a light shielding member for determining a shape of a photoelectric converting element of a signal detecting means. CONSTITUTION:When an objective lens is near media, a spot which is made incident on a sensor 102 becomes such an elliptical spot as is made incident on the sensor 102, and on the other hand, a spot which is made incident on a sensor 101 becomes a shape having a major axis of an ellipse in the direction being orthogonal to a major axis of the sensor. Also, when the objective lens is far from the media, the spot shape which is made incident on the sensors 101, 102 becomes a shape being reverse to that of the time when the lens is near the media, and in a focused position of the objective lens, it becomes a circular spot shape in both the sensors 101, 102. Accordingly, by taking a differential of both the sensors 101, 102, a focus error signal is obtained. In this case, a sensor 107 is placed around the sensors 101, 102, and non-reflective coating to wavelength of a sensor incident beam is performed onto each sensor, therefore, since light 105, 106 which does not contribute to a signal protruded onto the sensor 107 is scarcely reflected by the sensor 107, it becomes a stray light and does not return to an optical head.

Abstract: PURPOSE:To obtain the synthetic quartz glass crucible high in viscosity by sintering silica powder obtained by hydrolyzing alkoxysilane at a >=700 deg.C under reduced pressure, crushing the sintered body to reduce its adsorbed moisture content to <=0.03wt.%, melting the material with an arc flame and forming the material. CONSTITUTION:Silica powder obtained by hydrolyzing alkoxysilane is sintered at >=1700 deg.C under reduced pressure, crushed to reduce its adsorbed moisture content to <=0.03wt.%, melted with an arc flame and formed into a synthetic quartz glass crucible. The identicalSi-Siidentical bond in the glass reacts with the adsorbed moisture to form identicalSiOH group when heated with the arc flame to form the crucible, hence the bond is weakened, and the high temp. viscosity is decreased when the groups are increased. Accordingly, the content of OH group is decreased to <=80ppm to adjust the viscosity (log. eta) at 1400 deg.C to >=10.6 poise, and the crucible can be used to melt silicon for the semiconductor, etc.

Title: Semiconductor storing device
Inventor: SATO ISAO
IPC: G11C17/00
Filed: 1991-09-09
Abstract: PURPOSE:To hasten a charging speed without being affected by dispersion with individual and manufacturing error controlling the conduction of a first and a second loading means by a node potential changing based on one bias potential. CONSTITUTION:To the transistor TR84 of a load circuit LD3, a voltage lowering only by the threshold value voltage of the TR84 than a source voltage is supplied. Then, the potential when the initial charging TR84 is non-conductive is lowered only by the threshold value voltage than the potential when the TR31 of the load circuit LDI is non-conductive. Opposing to this, since the TRs31, 84 are controlled by the potential of a node NDA changing based on one bias potential, the TR84 is non-conductive faster only by the threshold value of the TR83. Then, the TR84 is turned on till the potential of the node NDA is approached to the non-conductive potential of the TR31. Thus, without being affected by the dispersion with the manufacturing error, the charging speed is hastened.
