Title: Pll frequency synthesizer type radio receiver
Inventor: MURAKAMI TAKESHI
IPC: H03J7/02
Filed: 1994-08-22
Abstract: PURPOSE: To stably start a PLL loop without causing an abnormality in locking of the PLL due to starting of the receiver or a band changeover. CONSTITUTION: A PLL stable start control section 9 linked by a device control section 7 by a radio operation key group 8 supporting the changeover device of an operating state of the receiver controls an LPF control circuit 11 for a prescribed time to release the operation of a PLL loop only for a start period of the PLL attended with the start of the device or the changeover. After the oscillation is started by boosting a VCO voltage forcibly to a stable voltage, a frequency division control section 6 restores the frequency division ratio to a prescribed frequency division ratio to improve the start characteristic of the PLL frequency control circuit.

IPC: H01L31/04
Filed: 1991-08-06
Abstract: PURPOSE:To provide a method for manufacturing a polycrystalline silicon thin film wherein its crystal particle size. is large and it can be formed in a short time. CONSTITUTION:The title manufacture is as follows: a silicon raw material is introduced into a high-temperature plasma generation part 1 in a film-formation apparatus whose main parts are constituted of the plasma generation part 1 for generating a high- temperature (several thousands to ten thousands  deg.C) plasma and of a reaction chamber 3 installed so as to be adjacent to it; the silicon raw material is melted or decomposed; and a polycrystalline silicon thin film is formed on a substrate 2. Since the silicon raw material is decomposed in the high-temperature plasma, silicon raw materials or metal-class silicon particles whose decomposition temperature is high and which have been difficult to apply in conventional methods can be applied. In addition, the melting or decomposition speed of the silicon raw material is made fast, and the supply rate of a molten or decomposed substance onto the substrate is made fast. As a result, the film-formation speed of the polycrystalline silicon thin film can be enhanced. In addition, since the whole process is executed under a high-temperature condition, it is possible to obtain the polycrystalline silicon thin film whose crystal particle size is large.

Title: Production of human tomorous cell degeneration factor (tdf)
Inventor: KISHIDA TSUNATAROU
IPC: A61K38/17
Filed: 1982-11-09
Abstract: PURPOSE:To obtain the titled factor capable of exhibiting the diminishing action specifically on only human cancerous cells, by dialyzing a culture fluid of a human fetal fibroblast against water, and adsorbing the dialyzate on an adsorbent under acidic conditions, extracting the adsorbed dialyzate with an aqeuous alkaline solution, heat-treating the resultant adsorbed extract, and subjecting the heat-treated extract to the gel filtration. CONSTITUTION:A human fetal fibroblast is cultivated, and a culture fluid is collected when the fibroblast is spread over the whole surface of the cultivation wall. The culture fluid is then filtered to remove insoluble foreign materials, and the resultant filtrate is fully dialyzed against water. The resultant inner dialyzate is acidified and brought into contact with a suitable adsorbent, e.g. kaolin or bentonite, to adsorb active constituents thereon. The active constituents are then extracted from the adsorbent with a weak alkaline aqueous solution, e.g. aqueous ammonia, and the above-mentioned extract solution is neutralized, heat-treated (at 60- 80 deg.C for 30-90min) and then subjected to the gel filtration to give the aimed human tumorous cell degeneration factor (TDF). In the above-mentioned cultivation, the TDF is produced in a high concentration by mixing the fibroblast with a human epithelial cancerous cell, and cultivating the resultant mixture. The diminishing action of the TDF on cancerous cells is enhanced by human leukocytic interferon.

Filed: 1988-08-08
Abstract: PURPOSE:To improve the clearness of a call to a receiver and to avoid giving unpleasant feeling by forming at least entrance part of a sound hole on an enlarging face which enlarges gradually as going from the inside of the sound hole to its external end. CONSTITUTION:The entrance part of each sound hole 3 is formed on an enlarging face 4 which enlarges gradually as going from the inside of the sound hole 3 to its external end and each enlarging face 4 is formed like a truncated cone which is linear in its section. Since an air stream 5 by an air stream by vocalization or a natural wind flows to the inside of the sound hole 3 smoothly by the enlarging face 4 of the entrance part of the sound hole 3, the turbulence and vortex of the air stream can be decreased. Consequently, broadband noise can be minimized extremely.
