Title: Deposition lamination method and laminate and window formed by using this method
Inventor: WATANABE HARUO
IPC: E06B9/24
Filed: 1992-11-20
Abstract: PURPOSE:To establish the method for easily producing the laminate having a liquid crystal which has excellent coloration and transparency and is free from air bubbles by heating an aq. soln. of a linear homopolysaccharide deriv. and water to cause clouding and flocculating of the linear homopolysaccharide deriv. and depositing the precipitate thereof on a substrate, then laminating a counter substrate on this substrate and to provide the window formed by using such laminate. CONSTITUTION:The ordinary transparent general aq. soln. consisting of the linear homopolysaccharicle deriv., the water and further, additives, such as water-soluble electrolyte, is heated to cause the clouding and flocculating of the linear homopolysaccharide deriv. and the flocculated precipitate thereof is deposited on the substrate. The counter substrate is laminated on this substrate after the precipitate is adjusted to the concn. exhibiting the liquid crystal. The aq. soln. consisting of the linear homopolysaccharide deriv. and the water is lower in viscosity, is more easily deformable and dissolves more uniformly as its concn. is lower. The hydrophobic bonding strength among the molecules of the linear homopolysaccharide cleriv. increases sharply when the high-viscosity aq. soln. is heated up even if this soln. has the high concn. The liquid viscosity decreases sharply when the state of the very small random clouded flocs is attained.

Title: Controller for detecting image blur
Inventor: NAGANO MASATOSHI
IPC: G03B17/00
Filed: 1993-12-28
Abstract: PURPOSE:To accurately detect a blur of image even when the image is subject to change depending on a state of an operating system by varying a detection characteristic of an image blur detection means depending on the state of the optical system. CONSTITUTION:When a hand-shake takes place while gi shake prevention switch is closed, an object image is moved on an image pickup face. A camera control circuit 21, a hand-shake detection circuit 41, a motion detection circuit 40, and an image pickup element control circuit 39 implement correlation operation between data of a representing point in preceding field and picture elements around the representative point in a current field to obtain a motion vector. Then the circuits discriminate whether the motion vector results from hand- shake or a movement of an object and move a range of an output pattern in parallel depending on the motion vector to correct the hand-shake. Thus, even when a field angle is changed by zooming and the image is moved, the blur of image is accurately detected.

Title: Heat treatment of porous film
Inventor: YAMAGUCHI HISAYA
IPC: B29L7/00
Filed: 1987-12-30
Abstract: PURPOSE:To obtain a porous film which is fully and uniformly oriented and improved in tearing strength, by shrinking a porous film obtained by biaxially orienting a filled polyolefin resin film under specified conditions. CONSTITUTION:A porous film obtained by biaxially orienting an unoriented film, prepared by forming a dispersion of an inorganic or organic filler (B) in a polyolefin resin (A) into a film, at a lengthwise orientation ratio of 2.0 or above and a crosswise orientation ratio of 2.0 or above is thermally relaxed at the lower temp. than the rosin m.p. to shrink it to an area ratio of 0.9 or below to obtain the purpose porous film. When the lengthwise orientation ratio or the crosswise orientation ratio is below 2.0, the film is uneven and poor in appearance because unoriented part remains to form patterns of islands or mottles. Further, such conditions cause a problem also in the stability of orientation and it is very difficult to perform orientation stably, especially in the case of a tubuler biaxial orientation. Further, uneven orientation is a factor disadvantageous for obtaining good gas permeability.

Title: Power plant supporting structure
Inventor: SATO SHIGEKI
IPC: F16F15/08
Filed: 1989-12-25
Abstract: PURPOSE:To reduce the vibration being input into a vibration isolator by supporting the vibration isolator on a shaft so as to be movable in the axial direction with respect to a bracket, and forming lockedly-engaging surfaces perpendicular to the axial direction in the portion where the vibration isolator is supported on the shaft, and also by arranging piezoelectric/electrostrictive elements between the respective lockedly- engaging surfaces and the bracket. CONSTITUTION:Piezoelectric/electrostrictive elements 30, 30a are arranged between the respective lockedly-engaging surfaces 28, 28a perpendicularly formed in the portion where a vibration isolator 10 is supported on a shaft and a bracket 20. By applying a voltage from the outside to the piezoelectric/electrostrictive elements 30, 30a so as to cause strain, the vibration isolator 10 supported on the shaft so as to be movable in the axial direction displaces in the axial direction in response to the strain of the piezoelectric/electrostrictive elements 30, 30a. Thus, by controlling the displacement of the vibration isolator 10 or the voltage to be applied to the piezoelectric/ electrostrictive elements 30, 30a in response to the input vibration, the vibration being input into the vibration isolator 10 accompanied by the resonance of the bracket 20 is reduced, and the transmissibility of vibration between a power plant and a vehicle body can be reduced.

Title: Rough route decision processing system
Inventor: SHIMIZU KATSUHIME
IPC: G06F17/50
Filed: 1991-11-25
Abstract: PURPOSE:To prevent a pass with strict delay constraint from running counter to delay constraint due to change when rough wiring processing is performed or detail wiring processing. CONSTITUTION:A delay analysis means 3 performs delay analysis with respect to each pass by using the delay value of a wiring layer with the maximum delay value and the virtual wiring length of each net. A contravention net extraction means 4 extracts the pass contravening to the delay constraint in the delay analysis, and finds the net comprising the pass. An optimum delay value wiring layer extraction means 5 finds a wiring layer which satisfies the delay constraint in the delay analysis under a virtual wiring length condition by the pass extracted by the contravention net extraction means 4. A contravention net rough wiring processing means 6 finds a rough route in which the length of the net found by the contravention net extraction means 4 can be equivalent to the virtual wiring length, and allocates the rough route to the wiring layer extracted by the optimum delay value wiring layer extraction means 5, and sets the rough route as a fixed one.

Title: Printer and its control method
Inventor: SAITO KENICHI
IPC: H04N1/32
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To surely perform the transmission/reception of data to improve the communication reliability and also to attain the fast communication by transmitting again the image data at a lower transmission rate if a transmission error is caused when the read image data are sent to a host device. SOLUTION: At the time of receiving the permission of transmission from a host, a printer stores the data obtained via the scanning into a buffer 3a of a RAM 3 and starts to transmit the data in a single data packet. If the host detects an error of the data based on a correct/wrong code that is added to the data, the host notifies the printer of the failure of reception of data and asks the printer to send the data again. The printer controls a communication controller 6 to secure a wait of 100 μs, etc., in every byte to transmit the data again. Thus, the data are transmitted again at a lower transmission speed to improve the reliability of communication and also to lower a retry occurrence rate. As a result, the deterioration of the total communication performance can be suppressed.
