Abstract: PURPOSE:To allow displaying with a high grade without the roughening of a screen by roughening the surfaces of substrates between picture elements to obtain the monostable orientation state of the ferroelectric liquid crystal between the picture elements. CONSTITUTION:A surface treating liquid 4 is applied on the surface of the substrate 1 between the electrode patterns of ITO 2 in order to roughen the surface condition of the substrate and is then subjected to temporary drying. The liquid prepd. by mixing colloidal silica and an aq. 1% PVA soln. as a binder is used as the surface treating liquid 4. This liquid is applied by an offset printing machine and spinner, etc. A resist 3 is peeled after drying of the coated film and the surface condition of the substrate between the electrode patterns of the ITO 2 is roughened in this way. The cell is thereafter assembled by the treatment complying with ordinary stages, by which the liquid crystal element is produced.

Title: Stopping method for power converter
Inventor: KONO HITOSHI
IPC: H02M7/48
Filed: 1989-12-22
Abstract: PURPOSE:To prevent an overcurrent stop at the time of starting by a method wherein the operation of a power inverting unit is stopped after stopping the operation of a power rectifying unit while delaying a predetermined period of time upon stopping the operation of a power converting device. CONSTITUTION:When an inverter 2 is stopped, a stopping command Stop is given to a gate control circuit 8A and a base driving circuit 8B. The base driving circuit 8B receives the stopping command Stop through a delay circuit 11 and continues switching operation for a predetermined delay time after stopping a power rectifying unit 2A. Accordingly, charges of a capacitor 4 are discharged into a heating coil 5 through a power inverting unit 8B whereby an excessive discharging current will never be conducted through the power inverting unit 2B from a capacitor 7 upon restart of the inverter 2.

Abstract: PROBLEM TO BE SOLVED: To continue a stable destruction by a simple structure by screwing a top portion of a hollow cylinder as a body with a cap and similarly closing a bottom portion with a member semi-spherically expanded to an axial and outward direction of the body. SOLUTION: In a hollow cylinder 2, i.e., a body of an impact energy-absorbing member 1, a bottom portion is closed by a semi-spherical bottom material 3. A female screw 5 is provided on a top portion of the hollow cylinder 2 and a cap 4 with a male screw 6 is screwed therewith. When an impact is applied to the impact energy-absorbing material 1 from above, the cap 4 is functioned as a trigger for destroying the hollow cylinder 2. Namely, the screwing portion of the cap 4 is destroyed to sink the cap 4 into the hollow portion of the hollow cylinder 2 and the cap 4 axially and outwardly enlarges the hollow cylinder 2 and destroys it.  At this time, since the bottom portion 3 of the hollow cylinder 2 is axially and outwardly, i.e., downwardly semi-spherically expanded, the hollow cylinder 2 is induced so as to be destroyed at a preferable state and the impact energy is efficiently absorbed to the maximum.
