Title: Catalyst for copolymerization of cycloolefin with acetylene
Inventor: FUCHIGAMI TAKAMASA
IPC: C08G61/00
Filed: 1995-04-27
Abstract: PURPOSE: To provide a catalyst used in the production of a cycloolefin/acetylene copolymer useful as a material for a gas separation membrane such as an oxygen enriching membrane by using a specified tungsten complex as an effective component. CONSTITUTION: This catalyst used for the copolymerization of a cycloolefin with an acetylene comprises a tungsten complex represented by the formula (wherein A<+> is an alkali metal cation, an ammonium cation or a phosphonium cation) or a combination thereof with a hydrosilane. This catalyst is stable, highly active and easily handleable. By using this catalyst, a copolymer having a composition corresponding to the composition ratio between the charged comonomers can be synthesized even in the copolymerization of a cycloolefin with an acetylene by which the production of a copolymer of a controlled compositionn is conventionally impossible, and a polymer of an acetylene can be used in the copolymerization. The synthesized cycloolefin/acetylene copolymer has excellent properties as a material for a gas separation membrane such as an oxygen enriching membrane.

IPC: H04N1/32
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent mis-detection of a facsimile incoming call signal. SOLUTION: Prior to reception of an object signal via a public telephone line from an opposite facsimile equipment, the communication equipment receives a facsimile incoming call signal from an exchange. A detector 4 detects only a facsimile incoming call signal to keep a signal level whose level is a reference level or over that is set by a detection condition setting section 22 continuously for a reference time or over among facsimile incoming call signals. After the detector 4 detects the facsimile incoming call signal, a facsimile equipment 1 is switched from a standby state to a reception state.  A correction discrimination section 21 discriminates the correction of the detected facsimile incoming call signal, and the detection condition setting section 22 sets a reference level and a reference time based on the discrimination result so as to allow the detector 4 to detect a correct call signal.

Title: Wind pressure rotating tire
Inventor: KASAMATSU TAKASHI
IPC: B64C25/40
Filed: 1995-03-16
Abstract: PURPOSE: To relieve wear due to friction between a tire and a road by a method wherein an wind pressure exerted from an advancing direction is exerted on a blade attached to the longitudinal groove of a tire, and a rotation force in an advancing direction is generated without a power. CONSTITUTION: A blade 2 curved in an advancing direction is mounted in the longitudinal groove 4 of a tire 1 with the tip thereof up. In this constitution, an wind pressure from an advancing direction exerts higher air resistance on the inner side of the blade 2 and a wheel is rotated in one direction. Thereby, for example, a frontward rotation is generated at a wheel lowered before landing of an aircraft and friction between a tire surface and a runway surface during landing is relieved. At a sliding period during take-off of the aircraft and during running of an automobile, a force to rotate frontward the wheel by means of an wind pressure is exerted. This constitution relieves wear due to friction between the tire and a rod and fuel consumption.
