Title: Production of bisphenol a purill
Inventor: FURUMOTO MASASHI
IPC: C07C39/16
Filed: 1992-04-17
Abstract: PURPOSE:To obtain a bisphenol A purill having a high strength and difficult to powder. CONSTITUTION:A method for producing the bisphenol A purill by solidifying the drops of the melted liquid of the bisphenol A comprises adding a reaction mother liquor or crystallization mother liquor produced in the bisphenol A producing process and contact-treated with a strong acidic cation exchange resin or zeolite to the bisphenol A or to the adduct or mixture of the bisphenol A to or with phenol, subjecting the mixture to a phenol-removing treatment and then granulating the treated mixture. Since the added mother liquor, etc., are the contact-treated product of the reaction by-products of the bisphenol A, the mother liquor, etc., are not only readily available but also do not give large effects to the physical properties, especially hue, etc., of the bisphenol A purill.

Title: Polymerization of 1-olefin
Inventor: TSUYAMA SHIGEO
IPC: C08F4/62
Filed: 1982-07-16
Abstract: PURPOSE:To produce a polyolefin of a wide MW distribution and high activity, by using a catalyst prepared by combining an organometallic compound with a solid component prepared by allowing an inorganic oxide to support a reaction product of a specified Cr component, an Mg component and a Ti (or V or Zr) component and calcining the oxide. CONSTITUTION:A 1-olefin is polymerized by using a catalyst comprising (A) a solid component prepared by allowing an inorganic oxide carrier (e.g., SiO2) to support a reaction product of a trivalent chromium compound containing the water of crystallization (e.g., hydrated chromium acetate or hydrated chromium nitrate), a magnesium alcoholate, e.g., Mg(OC2H5)2, and an alcoholate or oxyalcoholate of a transmition metal selected from Ti, V and Zr, e.g., Ti(O-n-C4H9)4, VO(O-n-C4H9)3, or Zr(O-n-C4H9)4, and calcining the carrier, and (B) an organometallic compound (e.g., triethylaluminum). This catalyst can show extremely high catalytic activity even at temperatures as low as below 100 deg.C and provide a polymer of an easily moldable MW and a wide MW distribution.

Title: Semiconductor integrated circuit device
Inventor: NINOMIYA KOICHIRO
IPC: H01L21/8242
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To avoid the decline in the power supply voltage fed to a column decoder, etc., as well as notably reducing the layout area for power supply wirings. SOLUTION: A pair of power supply lines 5 for supplying a column decoder 4 with power source are formed above the column decoder 4. The power supply lines 5 are connected to other multiple power supply lines 6 comprising power supply lines 6a for supplying a power source voltage VDD as well as ground wirings 6b for supplying a ground potential VSS. The power supply lines 6 formed of wirings between column selecting lines above a memory array 2 is able notably to decrease the decline in the power supply voltage fed to the column decoder 4, by dispersing the power supply using multiple power supply lines 6. Furthermore, since the power supply is dispersed by the power supply lines 6, the wiring width of the power supply lines 5 can be made narrow.

Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To easily extend an equipment and change an installation place by providing an exclusive slave set and plural master and slave common-usage sets and permitting the master and slave common-usage sets to attain a call with the exclusive slave set and the other master and slave common-usage set. SOLUTION: When a master set is called from the exclusive slave set 6, the slave set 6 calls the master and slave common-usage set 2 or 4 by a 19-channel and the use channel is reported. The master and slave common-usage set 2 or 4 sets the slave set transmission frequency f1 of the use channel as a reception frequency, sets a transmission frequency from the master set 2 of the channel being the same as that of the frequency as a master set transmission frequency and transmits a response signal to the exclusive slave set 6 by the 19-channel. When the response signal is received, the exclusive slave set 6 sets f2 as the reception frequency. Thus, the call is made between the exclusive slave set 6 and the master and slave common-usage set 2 or 4. The frequencies f1 or f2 is set in a same way when one of the sets 2 and 4 is operated as the slave set and the other is as the master set.

Title: Ice thermal storage unit
Inventor: SAKAE KATSUHIKO
IPC: F24F5/00
Filed: 1994-06-06
Abstract: PURPOSE:To increase an ice charging coefficient, to enhance a heat storage density, and to improve the cooling efficiency of an ice thermal storage unit by installing the fins of a heat transfer tube in a direction having a long distance to the adjacent transfer tube. CONSTITUTION:Fins 7 disposed on a heat transfer tube 4 are disposed in a zigzag array, and hence the tube 4 can be disposed in the vicinity with respect to a height direction. However, since there is a limit in the horizontal direction of the tube 4 due to the bent part of the tube 4 which needs a predetermined curvature in its structure, the distance between the tubes 4 in the horizontal direction of the tube 4 is lengthened. Therefore, the fins 7 are provided in the horizontal direction of the tube 4. Thus, since ice is also generated on the fins 7, an invalid area which cannot be heretofore used to generate ice can be effectively utilized, and the maximum value of an ice charging coefficient can be increased. Accordingly, the heat storage density of an ice thermal storage unit can be enhanced, thereby improving the thermal efficiency of the unit.

Filed: 1985-06-07
Abstract: PURPOSE:To provide a Pt alloy for an ornament consisting of prescribed weight percentages of Pt, Mn and Cu and having superior mechanical strength and castability as well as superior workability. CONSTITUTION:This Pt alloy for an ornament consists of 84-96wt% Pt, 1-10wt% Mn and 1-15wt% Cu. In the Pt alloy, Mn is added because it does not react with a casting mold during casting, can control the concn. of oxygen during casting and improves the mechanical strength and castability, and Cu is added because it forms an inter-metallic compound with Pt and further improves the mechanical strength by hardening. Since the Pt alloy has the above-mentioned superior characteristics, it is regarded as an epoch-making alloy substitutable for a conventional Pt alloy for an ornament.
