Title: Sealed laminate
Inventor: WATANABE HARUO
IPC: B32B3/02
Filed: 1994-01-25
Abstract: PURPOSE:To obtain a simple sealed laminate, in which neither development of bubble nor development of unevenness die to the change of concentration, is caused by surely preventing the solvent in liquid mixture from vaporizing by a method wherein layer containing the saturated vapor and/or liquid of the solvent is provided between the first sealing and the second sealing of the outer peripheral part of the laminate. CONSTITUTION:A sealed laminate is produced by sealing a laminate prepared by laminating boards, 1 at least some part of which is transparent, to liquid mixture 2 having easily vaporizable solvent. The preventive structure for preventing the solvent in the liquid mixture 2 from vaporizing is to provide second sealing consisting of a frame 5 outside first sealing consisting of sealing material 3 so as to produce the environmental field of saturated vapor due to the saturated vapor and/or liquid 6 of the solvent between the first sealing and the second sealing in order to establish the gas-liquid equilibrium with the laminated liquid mixture 2 at all times. By giving the environmental field of saturated vapor to the first sealing in presence of solvent, gas-liquid equilibrium is obtained, resulting in allowing to prevent the solvent from the liquid mixture from vaporizing from the liquid mixture 2. The amount of solvent to be held between the first sealing and the second sealing is insignificant and enough only when the amount of vaporization from the second sealing is taken into consideration for allowing to maintain the environmental field of the saturated vapor over a long period of time.

For example, a compsn. obtd. by adding 27 mol% of THF.17H 2 O to R11. 2 ∥O contains 6 wt% of THF. When this compsn. is stirred at several hundreds rpm while cooling to 0°C, it immediately begins to solidify and the temp. of the compsn. rises by about 3°C. After about 10 min, stirring is made impossible owing to a hydrate formed and the temp. of the compsn. becomes above 4°C. At the time of termination of heat generation, the compsn. is solidified to 100%, showing a m.p. of 8.1°C and heat of fusion of 68 cal/g. Thus, the compsn. has superior performance as a heat storing material for air cooling.

Filed: 1981-02-19
Abstract: PURPOSE:To achieve stable tracking and to avoid aberration, by fitting a lens barrel containing an optical device at one end of an arm, fitting a rotary drive shaft to another end and specifying the position of them. CONSTITUTION:A lens barrel 13 containing an optical device is fitted to one end of an arm 14, a rotary driving device 15 is fitted to another end of the arm 14 to constitute an actuator 100. Taking center shafts of the sahft 15a and the lens barrel 13 as O,O', the center of gravity of the arm 14 as G, and K2 as the radius of gyration of moment of inertia of the arm 14 relating to the G, the optimum position condition can be obtained with OO'=(K2+OG<2>)/OG.

Filed: 1991-02-19
Abstract: PURPOSE:To improve efficiency for a test by successively generating command information for loop control to a communication station as a test object after inputting designation information until reaching the number of times for the test, and judging the operated result. CONSTITUTION:When an input data is inputted from a key input device 84, a processor 81 sets the number of times for the test and transmits information corresponding to contents to execute control test to a packet preparation/decomposition part 85 so that the information and the command can be made into a packet successively and transmitted to a standby master station. The decomposition part 85 makes the received information into the packet and transmits the packet through a transmission/ reception part 86 and the standby master station to a transmission line. In respect to the packet transmission, while waiting for the reception of a response data packet from a receiving station for prescribed time, it is judged whether loop control can be executed or not. Namely, the decomposition part 85 decomposes this received packet, extracts the information and applies it to a processor 81. According to whether the received information of this response result can be obtained within prescribed time or not, the processor 81 judges whether control is normally executed or not.
