IPC: C01B33/32
Filed: 1988-05-30
Abstract: Crystalline sodium silicates having a layered structure and a molar SiO2:Na2O ratio of 1.9:1 to 3.5:1 are prepared from water glass solutions having a solids content of 20 to 65 % by weight by first treating the water glass solutions in a spray-drying zone. This gives a pulverulent amorphous sodium silicate having a maximum loss on ignition of 20 % by weight, while the waste gas leaving the spray drying zone has a temperature of at least 140 DEG C. The spray-dried sodium silicate is then heat treated in an ignition zone having a movable solid bed at temperatures of 500 to 800 DEG C for 1 to 60 minutes in the presence of at least 10 percent by weight of recycled material. This recycled material was obtained by mechanical comminution of crystalline sodium silicate discharged from the ignition zone.

Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device of high quality while avoiding degradation in the characteristics of the liquid crystal by mixing an adsorbent in a liquid crystal to adsorb organic impurities which deteriorate the characteristics of the liquid crystal. SOLUTION: An adhesive to adsorb organic substances such as phenols which degrade the characteristics of a liquid crystal is deposited on the face forming the sealing space of the liquid crystal (for example, on the surface of a spacer 6 or the like). In this liquid crystal display device, phenols produced in the liquid crystal are adsorbed by the adsorbent, and thereby, changes in the resistance, dielectric characteristics or voltage holding characteristics of the liquid crystal can be prevented, and high quality display can be realized. As for the adsorbent, for example, cyclohexyl groups (-C6H11) 7 are deposited (to modify) on the surface of each spacer 6. The cyclohexyl groups 7 act as adsorbing groups to adsorb phenols produced by decomposition of the aromatic ester liquid crystal due to irradiation of external UV rays.

Title: Receiving circuit of optical data
Inventor: SAKAMOTO FUKUMA
IPC: H04B10/00
Filed: 1981-08-21
Abstract: PURPOSE:To ensure the immediate transmission of the binary data corresponding to the optical data when a power supply is applied, by connecting a capacitor for stabilization of reference voltage and a holding capacitor to the power supply.

Title: Tracking controller
Inventor: IIDA MAKOTO
IPC: G11B7/095
Filed: 1991-06-03
Abstract: PURPOSE:To cancel the disturbance of a tracking error due to a scratch, and to improve a control characteristic by providing a delaying means to delay preceding beam voltage and a delay control means to vary delay time. CONSTITUTION:When the rotational linear velocity of an optical disk 1 is increased, the frequency of a reproduced synchronizing clock is increased, and the delay time becomes shorter. Because the rotational linear velocity is increased by the portion of the decrease of the delay time, the distance of advance per delay time is constant. Here, if the distance of the advance per delay time is set previously as inter-sub-beam distance, the disturbance of a tracking error signal is canceled even if the rotational linear velocity of the optical disk 1 is increased. Besides, in the case that the rotational linear velocity of the optical disk 1 is decreased as well, the disturbance of the tracking error signal is canceled similarly. Thus, by providing a frequency divider 16 as the delay control means, the delay time can be set even in the case that the optical disk 1 rotates unevenly, and controllability is improved.
