Title: Liquid crystal display element and its production
Inventor: YAMADA NOBUAKI
IPC: G02F1/1333
Filed: 1994-03-25
Abstract: PURPOSE:To enhance the practicality value, to attain a bright and high contrast and to eliminate the uneven display by putting liquid crystal regions into a selective reflection state and setting the chiral pitch in a polymer shorter than the chiral pitch of the liquid crystals contained in the liquid crystal regions. CONSTITUTION:This liquid display element has a microcell structure having the liquid crystal regions 3 enclosed by polymer walls 4 between a pair of electrode substrates 1, 1 both having electrodes 2. The polymer walls 4 are in close contact with or adhered to each other by both upper and lower electrode substrates 1, 1 and the high polymer walls 4 themselves unlike the polymer walls obtd. by a method of previously forming the polymer walls 4 on the one electrode substrate 1, then forming cells and injecting a liquid crystal material into the cells, thereby, the fluctuation in the cell thickness against external force is suppressed, discoloration, etc., are prevented and impact resistance is improved. Further, the chiral pitch in the polymer is set shorter than the chiral pitch of the liquid crystal material. The chiral materials are, therefore, taken into the polymer by photopolymn.

Title: Braking system for electric motor vehicle
Inventor: MIYASHITA ICHIROU
IPC: B60L7/22
Filed: 1980-04-30
Abstract: PURPOSE: To obtain necessary braking force by flowing an electric current through the specific two phases of the three-phase winding of a squirrel-cage induction motor in a predetermined direction when a regenerative braking fails, thereby dynamically braking an electric motor vehicle.  
     CONSTITUTION: If a regenerative braking fails due to the lack of a driven vehicle at a DC trolley wire side when the rotating energy of a squirrelcage induction motor 7a is regenerated through a PWM inverter 6 at the DC trolley wire side to allow the vehicle to regeneratively brake, the regenerative brake is stopped and reverse conducing thyristors 6UW6Z constructing the PWM inverter 6 are controlled to supply a direct current to the two phases of the motor 7a. Thus, the motor 7a is dynamically braked with the direct current. In this manner the dynamic braking can be performed without adding a specific main circuit configuration when the regenerative braking fails in the vehicle.

Title: Superconducting element
Inventor: HATANO MUTSUKO
IPC: H01L39/22
Filed: 1991-03-20
Abstract: PURPOSE:To obtain a superconducting element which has a large gain, and is suitable for high speed operations by introducing electrons or positive holes having an energy which is lower than, or the same as, an energy gap of a superconductor into a boundary surface from a normal conductor side, and by controlling a reflective index and the amount of reflected electrons or positive holes. CONSTITUTION:When carriers are injected into a semiconductor 2 from a normal conducting metal 3 with an energy which is lower than a gap energy of a superconductor, the Andreyev reflection occurs at the boundary between a superconductor 1 and a semiconductor 2. When an electric field is applied to control electrodes 4 and 5, excess currents increase, and the current-voltage characteristic of a current between the normal conducting metal 3 and the superconductor 1 is changed because of a control voltage. Excess currents less than the voltage which is equivalent to an energy gap DELTA1 of the superconductor are controlled by a voltage applied to the control electrodes. Thereby, it is possible to realize a superconducting element which performs high speed operations; consumes less power; provides improved gain due to excellent I/O separation; and has a fast switching speed.

IPC: B21D28/24
Filed: 1989-03-09
Abstract: PURPOSE:To enable selection between the use when the work of piercing hole is required and the used when it is not required by attaching a button die on one side of a pair of die, attaching a piercing punch on the other side and switching selectively their position by moving the piercing punch in the axial direction. CONSTITUTION:When an upper die 4 is lowered in the state that a flange part 23 is seated on the step part 32 of a punch retainer 22, the piercing hole H is formed by engaging the tip of the piercing punch 21 with the button die 20 of the other side at the position of bottom dead center. When a sleeve 27 is rotated in the direction of the arrow (m1) by operating a pneumatic motor 28, the whole of the piercing punch 21 is lifted by a stroke C until the flange part 23 is seated on the lower end face of the sleeve 27 by the screwing action of a female screw part 31 and a screw shaft part 24. Even if the upper die 4 is lowered in that state, the piercing punch 21 isn't engaged with the button die 20 at the position of bottom dead center of the upper die 4. Thus the surrounding space of the punch can be saved by arranging the screw member, etc., with which the position of the punch is switched according to the necessity or not of piercing work, on the same axial line.
