Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To reduce thermal stress at the time of solder reflowing and to prevent peeling-off occurring at a part below a chip, by constituting a circuit board where a semiconductor chip is loaded by means of combining a base material and a coat, whose elasticity and thickness are decided in specified ranges. SOLUTION: In a board 1 on which a semiconductor chip 3 is loaded and which has a circuit wiring, the board 1 is composed of a base material whose elasticity at 200 deg.C is not less than 800 kg/mm<2> and whose thickness is 0.2 mm-0.8 mm, and a coat whose elasticity at 25 deg.C is 50 kg/mm<2> and whose thickness is 30-80 μm. Since elasticity of the base material used for the circuit board is high, thermal deformation by heat at the time of solder reflowing is less and thermal stress generated below the chip can be reduced. Then, the coat whose elasticity is comparatively low is formed on the base material, therefore a thermal expansion coefficient difference between the chip and the base material can be relieved, and generated thermal stress can be reduced.

Filed: 1992-12-28
Abstract: PURPOSE:To deal with addition or modification of sensor easily without modifying a general purpose program by providing a data table containing inherent data required for driving each sensor device and combining the data table with the general purpose program. CONSTITUTION:A data table 22 contains inherent data required for controlling all sensor devices 16 connected therewith and for collecting/operating data. A CPU10 selects a device 16 to be driven, e.g. a two-dimensional image sensor 16A or an additional one-dimensional distance measuring sensor 16B, based on an external input signal or a program. The CPU10 then reads in a general purpose program 20 and controls the sensor 16A or 16B according to a control program while looking up the part of the sensor 16A or 16B in the table 22 thus collecting measurement data and performing predetermined operations. Consequently, addition or modification of the sensor device 16 can be dealt with by simply modifying the table 22 without requiring modification of the program.

Title: Eyelash curler

IPC: A45D2/48
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To beautifully curl only a part of eyelashes by narrowing an inner width of bifurcated lever parts more than the width of an eyelid, and forming a molded plate and a movable support frame in a narrow width corresponding to the bifurcated lever parts. SOLUTION: When both finger hooking parts 1a and 4a are actuated so as to approach each other, an elastic receiving seat 6 of a movable support frame 5 is brought into pressure contact with the lower edge of a molded plate 3, and eyelashes can be curled. In this case, an inner width of bifurcated lever parts 2 and 2 is formed narrower than the width of an eyelid, and both the molded plate 3 and the movable support frame 5 are formed in a narrow width. Therefore, a collar does not entirely cover the whole eyelashes, and only eyelashes close to an internal can thus can be beautifully curled. Since the upper edge of the elastic receiving seat 6 sandwiching eyelashes is formed narrower than the inner width of the bifurcated lever parts 2 and 2, eyelashes more than necessary are not obliquely moved against her will, or eyelashes obliging from the roots are not curled by mistake. Therefore, they can be finished as a twistless, straight and beautiful curl.

Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To control rigidity of an engine mount by arranging a stopper plate extending laterally inside a pot-like housing and having an aperture and controllably abutting a control plate elastically fixed to the pot-like housing with the stopper plate. SOLUTION: A control plate 25 is controlled/switched in relation to a present control pressure. In a first position in which the control plate 25 is brought into contact with a stopper plate 18 for closing an aperture 19, a highly rigid engine mount is arranged. The engine mount works in the similar way as a passive single chamber type hydraulic mount. Static rigidity of the engine mount is decided on the basis of rigidity of a bearing spring 1 and the volume rigidity of hydraulic damping. A plate 22 served as a stirring body acts for insulating a high frequency vibration.  When the control plate 25 is brought into contact with a bottom plate 29 in a pot-like housing 7, the aperture 19 of the stopper plate 18 is opened, and the lower chamber 9 is provided with a large capacity, while a pressure of the upper chamber 8 is lowered, and consequently, rigidity of the engine mount is reduced.
