Title: Producing vessel for fluidized treated soil
Inventor: KATSUTA TSUTOMU
IPC: B28C1/16
Filed: 1995-04-18
Abstract: PURPOSE: To facilitate transferring and cleaning after use. CONSTITUTION: Since a vessel body 7 is formed with a flexible sheet, it is light. And since it can be compactly contained by folding, it can be easily carried and hence, it can be easily installed even in an inconvenient site which is hard to get to. And further, since the vessel body is formed with a flexible sheet, the solidified fluidized treated soil 5 can be easily peeled off by striking the flexible sheet from the outside, even though the fluidized treated soil 5 sticks to the inside face of the vessel body 7 and gets solid thereon after use. Accordingly, cleaning work after use is extremely easy and the working time can be reduced.

Title: Liquid crystal display device
Inventor: TAKANO HAJIME
IPC: G02F1/133
Filed: 1985-04-29
Abstract: PURPOSE:To obtain a liquid crystal display device which has an invariably optimum light-dark state regardless of temperature characteristics and a secular change by providing a voltage control circuit which controls the voltage of the driving signal of a signal source according to the quantity of light transmitted through a liquid crystal display body. CONSTITUTION:When an image is displayed, a variable voltage source 22 is normally set to the same voltage with a conventional constant voltage source and the driving signal 6 is outputted with its source voltage. If the driving signal 6 outputted from a signal source 26 does not have an optimum voltage owing to temperature characteristics, etc., and the quantity of light transmitted through the liquid crystal display body 19 decreases below, for example, an optimum value, an electric signal converted by a photoelectric converting means 20 photoelectrically drops below a reference electric signal. Then, a signal which is in inverse proportion to the difference is outputted from a comparing means 20 and an amplifying means 23, so the voltage of the variable voltage source 25 varies to lower the voltage of the driving signal 6 and the voltage of the driving signal 6 is controlled so that the quantity of light transmitted through the liquid crystal display body 19 is optimum. Consequently, the best light-dark state is maintained at any time regardless of temperature characteristics and a secular change.

Filed: 1989-04-14
Abstract: PURPOSE:To readily obtain a high quality film with a uniform film thickness and having no any defects such as pin holes or the like by constantly controlling the film material viscosity of a coated film immediately before the coat film is wound. CONSTITUTION:After the dope is coated on a mold release film in a uniform thickness, and in the process wherein the coating material is wound in a state of being kept the fluidity, a coat film is manufactured by spraying a certain constant temperature gas within the range of + or -20 deg.C on a film immediately before being wound. At this time, the dope (coating material) as a film material has a degree of the viscosity or higher that it may not flow as coated on the film, and as the viscosity of the dope is so high, it becomes hard to spread over the whole of the film. On the contrary, the viscosity of the dope is very low, it becomes hard to mold a film. That is, it is necessary for the dope to have a degree of viscosity capable of being coated on the film uniformly, and it may be suitable for it in 1000-30000cp in ordinary, and preferably in 2000-20000cp.
