Title: Frame for absolutely keeping horizontally
Inventor: MIDORIKAWA HIROSHI
IPC: G01C9/00
Filed: 1992-10-29
Abstract: PURPOSE:To always keep a table horizontal by supporting the horizontal table by means of a plurality of electromagnetic actuators, detecting the horizontality of the table, and driving an actuator in accordance with a signal indicating it. CONSTITUTION:A horizontal table 1 is supported on a floor F by means of a plurality of electromagnetic actuators 2a-2c. The actuators 2a-2c are operated to levitate the table 1 and then a gyro 6 is actuated to detect the pitch and roll angles of the table 1. An adder 7 adds together the reference value signal of zero table angle and the minus signal of the pitch or roll angle from the gyro 6 to determine whether or not the pitch or roll angle is zero. When both of the angles are zero, detection is repeated, whereas when both are not zero the amount of current fed to the actuators 2a-2c is decided using a control circuit 8 to control the amount of levitation so as to keep the table 1 in a horizontal state. The above process is constantly repeated to keep the table 1 horizontal.

Title: Under color eliminating device
Inventor: HIBI YOSHIHARU
IPC: B41J2/525
Filed: 1985-12-24
Abstract: PURPOSE:To attain an under color elimination with less degrading in density and saturation by applying an under color elimination processing unconditionally to an achromatic color but varying the amount of said elimination according to the degree of saturation of a chromatic color. CONSTITUTION:The respective minimum values KMIN and maximum values KMAX of chrominance signals Y1, M1, and C1 obtained through conversion-processing of respective colors B, G, and R, are detected by a minimum-value detecting circuit 1 and a maximum value detecting circuit 2. Then the value of (KMAX-KMIN) is obtained, and a color which is not an achromatic color but of not-so-high-degree of saturation is decided by a value (KMAX-KMIN)not equal to 0. Also, the coefficient of a signal K2 outputted from a black component calculating circuit 3 is set at r1=0.5. This means that, since the color is a chromatic color, the amount of a black component is set moderate in comparison to the case of an achromatic color. Next, the coefficient of a K1 which is to calculate a correction value is set, for instance, at r2=0.5, to calculate Y2, M2, and C2. In case the under color elimination is executed in such a way, a black picture point does not change, and picture points Y and R that do not positionally coincide with the black point are generated separately. Therefore, the degrading of a chromatic color's saturation can be made not noticeable.

Filed: 1992-10-30
Abstract: PURPOSE:To house a electrode plate group easily in a battery jar by using synthetic resin formed by adding a filler of a thermally expansible plastic hollow body as a pressurizing spacer used to pressurize the plate group. CONSTITUTION:A plate formed by adding a thermally expansible filler by 5weight% to a P.P plate is used as a pressurizing spacer. Here, isobutane composed of vinylidene chloride acrylonitrile copolymer is used in the filler. Thickness of a spacer 5' is set in 0.5mm, and this is arranged in both end parts of a plate group 4'. Though thickness of a positive electrode plate 1, a negative electrode plate 2 and an electrolyte holding body 3 is the same as usual, the total thickness of the plate group 4' is set in 21.6mm. Thereby, when the plate group 4' is housed in a battery jar 6 having width of 22mm, it can be housed in a wholly non-pressurized condition. Afterwards, the spacer 5' is expanded by adding heat while using a heating iron, and thickness of the spacer 5' after being expanded is set in about 2mm. In this way, nonuniformity of pressurization in the plate group is reduced, and nonuniformity is prevented from being caused in battery performance such as capacity or a service life.
