IPC: C09J7/02
Filed: 1981-02-18
Abstract: PURPOSE:To prevent the increase in electric current consumption and the increase in gap value on account of elution of adhesives into a liquid crystal by using a small amt. of a photosetting type adhesive for the part of the sealing hole of a liquid crystal display element to be in direct contact with the liquid crystal and sealing the outer side thereof by means of a thermosetting type adhesive. CONSTITUTION:After substrates 1, 2 are sealed by using a sealing material 3, a liquid crystal 5 is injected therein at room temp. through a liquid crystal sealing hole 4. Thereafter, first an UV curing adhesive (polybutadiene acrylate type or the like) 6a is coated in the hole part 4 and is left standing at temp. slightly lower than room temp. to allow the adhesive 6 to enter the inside of the hole 4, after which UV rays are irradiated at the low temp. to set the adhesive. Next, a thermosetting adhesive 6b contg. a liquid epoxy resin and a hardener is coated on the element end face in such a way as to cover the adhesive 6a, and is set by heating. Thus, the adhesive 6a does not absorb the liquid crystal 5 or dissolve in the liquid crystal and the adhesive 6b is strong in adhesive power; hence, the reliability and durability are improved without causing the fluctuation in the liquid crystal thickness (gap) and the increase in electric current consumption.

Title: Measuring method for riding rate
Inventor: ARAI SHIZUO
IPC: G01G19/08
Filed: 1988-02-03
Abstract: PURPOSE:To grasp an accurate riding rate by regarding the weight of a car body from a car barn to a starting station as empty car data and data after the starting station as actual car data. CONSTITUTION:The on-state of a power source is confirmed and the empty car data is inputted. Then when the doors are opened at the starting station, passengers enter the cars, but when the cars stop, an accurate variation quantity is not indicated possibly because of the structural characteristics of booster springs 10a and 11a. Therefore, when the weight at this time is measured, an error is easy to occur. Consequently, when the doors are opened, the empty car data which is already inputted is stored and it is judged that the doors are closed for starting. When the train starts and enters a constant-speed traveling state, the vehicle weight is applied uniformly to the front and rear axles. In this state, even when the weight after passengers ride on is measured, there is not any error due to the unbalance of the weight, so the actual car data is inputted and a measuring instrument 10e calculates and displays the riding rate according to the empty car data and actual car data which is measured this time.

Abstract: PURPOSE:To make it possible to achieve miniaturization with electric connection being kept between the first main electrode and the third semiconductor layer by exposing the third semiconductor layer in the second region, which is specified at a part of a region that is substantially held with the stripe-shaped third region. CONSTITUTION:In UMOS-IGBT 110, an N<+> emitter layer 206 us exposed in the ladder shape on the upper main surface of a semiconductor substrate 200 held with a groove 207. Therefore, even if the position of a stripe-shaped region Ra, which is the contact surface of an emitter substrate 212 and the upper main surface of the semiconductor substrate 200, is deviated, the electric contact between the N<+> emitter layer 206 and the emitter electrode 212 is ensured. Furthermore, even at the rectangular exposed surface of a P-base layer 205 surrounded with the exposed surface of the ladder-shaped N emitter layer 206, the electric contact with the emitter electrode 212 is ensured by the same way. Since redundant design is not required in this way, there is the advantage of easy miniaturization of a unit cell.
