Patent JP-S56115042-A (JP)
Title: Equalizer of variable group delay time
Inventor: IGARASHI TAKAHARU
IPC: H04B7/005
Filed: 1980-02-18
Abstract: PURPOSE:To realize an optional variation for both the central frequency and the band, by varying the central frequency of the group delay time characteristics that is generated by two resonance circuits. CONSTITUTION:The capacitors C10 and C20 in the resonance circuits 201 and 202 each are made variable, and thus the central frequency of the group delay time characteristics generated from these resonance circuits can be varied. The overal group delay time characteristics of these resonance circuits is obtained by sunthesizing the group delay time characteristics generated from the circuits 201 and 202 each. Accordingly the band can be varied without varying the central frequency in case the the group delay time characteristics generated from the circuits 201 and 202 are equal to the central frequency in terms of plus and minus. While in case the group delay time characteristics of these two resonance circuits are not equal to the central frequency in terms of plus and minus, the central frequency varies for the circuit. Thus both the central frequency and the band can be varied optionally by just giving a control to the capacitors C10 and C20 each.

Filed: 1989-01-26
Abstract: PURPOSE:To make an operator appropriately pay attention to eyeless points by a method wherein at least either illumination color or brightness of the eyeless points is made variable and controlled by a controlling means. CONSTITUTION:A plurality of light emitting elements 22 having different illumination colors are used as eyeless points to be placed on the side of an apparatus 21, while light adjustment such as flashing and light emitting intensity of the elements 22 is controlled by a controller 23. To the controller 23, a changeover switch 24, a timer 25 a memory 26 for storing data to control flashing of the light emitting elements 22 and a sensor 27 are connected in order to change state of light adjustment of the elements 22. Since this enables at least either illumination color or brightness of the elements 22 to be changed, this allows an operator of an office automation machine or the like to pay attention without being used to the eyeless points so that fatigue of the operator's eyes can be excellently reduced.

Title: Color filter and its production
Inventor: TOYOSAKI TAKAYUKI
IPC: G02B5/20
Filed: 1994-02-16
Abstract: PURPOSE:To obtain a color filter having satisfactory adhesion to all over the surfaces of the transparent substrate and transparent protective layer and to obtain a color filter having satisfactory adhesion and high reliability. CONSTITUTION:When a colored layer, a light shielding layer and a transparent protective layer are disposed on a transparent substrate to produce a color filter, an adhesive layer of polyimide resin is interposed between the protective layer and the light shielding layer so that the adhesive layer exists in a region in which at least one of the light shielding layer and the colored layer in the color filter exists and the objective color filter is obtd. Since the adhesive layer is chiefly formed on the colored layer and on the light shielding layer, the adhesion of the protective layer to the light shielding layer is improved. Since the protective layer adheres directly to the part of the substrate on which the colored layer and light shielding layer are not disposed, the adhesion of the protective layer to the part of the substrate is improved.

Abstract: PURPOSE:To improve safety in an active suspension during ignition switch-off by releasing high pressure operational liquid reserved in an accumulating source, with a control valve for relief opened, into a reservoir tank. CONSTITUTION:When an ignition switch is turned 'off', suction and exhaust control valves 15, 19 are sensed and the pressure of an accumulator 22 is detected by a sensor 64. If the detected pressure is not more than a predetermined value, for example, 100kgf/cm<2> or less, a control valve for relief 26 is opened. In the case it is not less than a predetermined value, when the predetermined period of time passes by after the ignition switch-off, for example, after two minutes pass by, the control valve 26 is opened for relief. When the predetermined period of time passes by after the control valve 26 is opened, for example, after 5 seconds pass by, the pressure of the accumulator 22 is detected so as to examine if it is reduced to a predetermined value or less. Unexpected elevation of a car is prevented, and safety can thus be improved with the structure.
