Title: Crystallization dephosphorization method
Inventor: SUGIMOTO BISEI
IPC: C02F1/58
Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a crystallization dephosphorization method capable of stably ensuring the amount of demand, and utilizing an inexpensive inorganic porous body. SOLUTION: Phosphate ion-containing water is contacted with the inorganic porous body under the presence of calcium ions in a pH value range of 9 to 11. Contrasted with the conventional crystallization reaction in a metastable region in which calcium phosphate is deposited only on the surface of a crystal seed containing the calcium phosphate, the crystallization reaction can be stably conducted in an unstable region in which the calcium phosphate is deposited without existing the crystal seed of the calcium phosphate by adjusting the pH value. That is, in the unstable region, fine crystal of the calcium phosphate is deposited in liquid. The fine crystal is captured in small holes of the inorganic porous body and becomes a new crystal growth point of the calcium phosphate. The crystal growth point increases, as a whole, thus the crystallization reaction is promoted.

Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for molding a resin pipe which can easily form a recessed shape on the surface of the resin pipe by a simple apparatus, and an apparatus for the method.

Title: Waveguide grating and method for manufacturing the same
Inventor: SATO SHINOBU
IPC: G02B6/122
Filed: 2001-10-10
Abstract: PROBLEM TO BE SOLVED: To provide a waveguide grating having a low leaky mode coupling loss and a method for manufacturing the waveguide grating. SOLUTION: In the waveguide grating which is made by irradiating a core 2 with ultraviolet light, the coupling between a waveguide mode and the leaky mode is decreased by making the thickness of a clad 3 15 μm or more. The decay in the leaky mode when propagating in the clad 3 is increased by flattening the upper surface of the clad 3 by a chemical mechanical polishing (CMP) and the influence of the leaky mode coupling is further decreased. Thus, the loss due to the leaky mode coupling is suppressed to 0.5 dB or smaller and the loss which appears on the side of a wavelength shorter than a Bragg wavelength is decreased.
