IPC: F28D7/16
Filed: 1986-04-18
Abstract: PURPOSE:To extend a lift of thermal pipes by a method wherein closing plates 10 capable of closing thermal conductor pipes are arranged at both ends of a plurality of thermal conductor pipes not required as a thermal conducting plane during winter season so as to terminate a flow passage of sea water. CONSTITUTION:Sea water enters a water chamber 7 at a water chamber inlet nozzle 8, is divided into several thermal conducting pipes 1 attached to a pipe plate 6 and then exists out of the water chamber and again is divided into thermal conducting pipes and flows out of an equipment through water chamber. Medium to be cooled flows into a barrel 2 at a barrel inlet nozzle 4, is guided to a baffle 3 arranged to get a proper flow speed and repeat a zig-zag flow, perform a required heat exchange and then flow out at a barrel outlet nozzle 5. A sea water heat exchanger using as its cooling source sea water has a surplus thermal conducting area due to a low temperature of sea water in winter season. Closing plates 10 are forcedly pushed at the right and left thermal conducting pipe ends at this surplus part so as to be close the pipe ends. Therefore, the sea water does not flow into the thermal conducting pipes and a corrosion and etching etc. are prevented. A repetition of such a use in sequence very winter causes a life of the unit to be extended more than the case in which all the thermal conducting pipes are used with sea water circulating in them all the year round.

Title: Temperature sensitive light intercepting material and its preparation
Inventor: ICHIHASHI TAICHI
IPC: G02B5/20
Filed: 1983-05-19
Abstract: PURPOSE:To permit control of light transmittance in accordance with change of temp. by using water-contg. polyacrylic acid gel. CONSTITUTION:Water-contg. polyacrylic acid gel used here is obtained by polymerizing methacrylic acid monomer prepared to 12-27vol% aq. soln. in the presence of a polymn. initiator, and the gel is placed in a transparent vessel of glass or the like, and provided for practical use in a sealed state. It is transparent and uniform, transmitting light at low temps., but opacified at higher temps., presumably due to rise of bonding strength among each polymer molecule at higher temps., and causing difference in densities in innumerable parts, resulting in diffused reflection and interception of light transmission. This temps. causing change of light transmittance is affected by the content of gel, and can be finely adjusted by the addition of compds. having a hydrophilic group, such as =O, -OH, or -NH2. Such polyacrylic gel is extremely effective as a stable and highly responsive temp. sensitive light interceptive material.

Title: Driving method for active matrix type liquid crystal display device
Inventor: TANAKA TAKAAKI
IPC: G02F1/1337
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To reduce flowing and trailing of an image on a screen at the time of high-speed driving. SOLUTION: A voltage V is applied to a liquid crystal in a period Tw corresponding to a selection period and a following nonselection prod (hold period) in one frame period Tf. Then, the voltage applied to the liquid crystal is held at 0 in a reset period Tr which is in the one frame period Tf and before the selection period of a next frame begins. Consequently, the liquid crystal in an array state when the voltage V is applied shifts to an array state of approximately 0 in transmissivity. Thereby the influence of the array state of liquid crystal molecules in the last frame is eliminated at the time of driving in the next frame, and flowing and trailing of an image can be eliminated.
