Title: Manufacture of easily-openable lid formed of thermoplastic resin laminated metallic plate excellent in corrosion resistance
Inventor: NISHIDA HIROSHI
IPC: B21D51/44
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide an easily-openable can lid formed of steel sheet which is excellent in can opening property, unnecessary for repair coating of inner/outer surfaces, and excellent in corrosion resistance with excellent productivity by forming a cut guide groove in the press in a plurality of stages in manufacturing the easily-openable can lid by achieving the pressing at a shoulder part of upper and lower dies for forming the cut guide groove to constitute the shape of an opening piece with a metallic sheet with a resin film as a stock. SOLUTION: When a metallic sheet 1 is pressed at shoulder parts of a punch which is an upper die and a die which is a lower die with the shoulder radius R, the residual sheet thickness is distributed symmetrical in the right-to-left direction. When the working rapidly achieved in one pressing so that the thickness of the metallic sheet 1 is 1/2 or less of the original value through the pressing at the shoulder parts of the upper and lower dies, a very large shearing force works between the metallic sheet and a resin film, and the adhesive force between the metallic sheet and the resin film is reduced. To reduced the shearing force, the pressing is achieved in multiple stages (e.g.: 2-4 times) while the working quantity in one time is reduced. The resin film of 10-100 μm and >=200% in breaking elongation is used on one side.

Title: Closing mechanism
Inventor: KASAI KAZUAKI
IPC: B41J29/13
Filed: 1988-03-16
Abstract: PURPOSE:To reduce the number of component parts to simplify a closing mechanism as well as to obtain a small-size electronic equipment, by a method wherein, the center of a bar spring is held by a body case, and the engagement state between an upper case and the body case is kept by claw formed on the body case and the upper case. CONSTITUTION:A spring 3 is flexuously hooked on a spring hooking part 1b of a body case 1. A force acting in the direction of expanding an open part of the body case 1 and a force pulling an upper case 2 toward the spring hooking part always act on the upper case 2. A lock claw 1c of the body case 1 and a lock claw 2c of the upper case 2 are always kept in an engaging state by a deflecting force of the spring 3. To open the upper case 2, the upper case 2 is pulled toward the open part along the body case 1, whereby the lock claw 2c of the upper case 2 is disengaged from the lock claw 1c of the body case 1 for the release of the force, and the upper case 2 is pulled back to the center of rotation 1a' of a bearing of the body case 1 by the elastic force of the spring 3 to be released from the body case 1. Since the body case 1 and the upper case 2 can be opened/closed by one piece of bar springs, the reduction of the number of component parts and a simple structure are made possible.

Filed: 1983-04-07
Abstract: PURPOSE:To adjust the direction of a receiving antenna accurately and easily by knowing the electric field intensity of a radio wave received by the receiving antenna only by connecting a simple instrument to a terminal for testing provided to an outdoor unit. CONSTITUTION:An indoor unit 30 detects the reception level of the radio wave received by the outdoor unit 2 and sends out the detected reception level to the outdoor unit, which is provided with the testing terminal 13 which outputs the reception level supplied from the indoor unit. A low-frequency signal which varies in amplitude with the reception level of the radio wave appears at the testing terminal 13. For this purpose, the amplitude of the low-frequency signal led out to the testing terminal 13 is measured to know the reception level of the receiving antenna 1, i.e. electric field intensity of the received radio wave. Therefore, the direction of the receiving antenna 1 is so adjusted that the indicated value of an AC voltmeter is maximum, installing the receiving antenna 1 accurately in the arrival direction of the radio wave.

IPC: C08F2/00
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a massive polymer in the conventional fluidized bed vapor-phase polymerization process and realize a long-term stable polymerization reaction. SOLUTION: A process for the continuous vapor-phase polymerization of olefins in a fluidized bed reactor, wherein a circulating gas containing an unreacted monomer discharged from the reactor and a supplementary monomer is cooled in such a manner as to satisfy the relation of the formula Td<T<Td+5 deg.C (wherein Td is the dew point of circulating gas, and T is the cooling temperature of circulating gas) and introduced into the reactor, while the inner wall of the reactor is cooled to a temperature equal to the dew point of the circulating gas or lower. The vapor-phase polymerization can be thereby performed stably without the occurrence of a massive polymer, especially, e.g. a sheetlike mass, caused by the unstable temperature in the fluidized bed due to the local accumulation of polymerization heat.
