Title: Liquid crystal display element
Inventor: MIYATA KEITARO
IPC: G02F1/1335
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display element with which the easy control of the cell thickness is possible and which has good display characteristics by providing this element with a front substrate, a rear substrate, a sealing material, liquid crystals and a light shielding film. SOLUTION: A shielding case 42 is formed by covering the circumference of a non-display area exclusive of the notches at four corners for the purpose of a polarizing plate having a rectangular shape and a black mask 32 is formed by notching the inner periphery of the sealing material SC. The light shielding film 24 covers a contact region and the inner periphery of the sealing material SC and, therefore, these notches are shielded of light by the light shielding film 24 and the leakage of light from a back light is suppressed. The light shielding film 24 is formed simultaneously in the process of forming a data line DL and, therefore, the light shielding film is easily constituted without increasing production stages.  Further, the light shielding film 24 has a role of wirings for connecting counter electrodes and compensation capacitor electrodes and, consequently, three is no need for disposing the connecting lines to be used exclusively for connecting the connecting terminals of the compensation capacitor electrodes and the counter electrodes exclusive of the light shielding film 24. The wiring structure is thus simplified.

IPC: H02P6/08
Filed: 1993-12-24
Abstract: PURPOSE:To provide a control circuit for a brushless motor capable of variably controlling a braking force by using a low-function microcomputer. CONSTITUTION:Switching means 3 for setting a plurality of coils of a motor 1 to short-circuit conditions and also a control means 4 for ON/OFF controlling the switching means 3 over a phase interval based on an electrical angle of a motor 1 are provided, and the control means 4 selectively controls the phase intervals so as to thin off the phase intervals. By doing this, each coil is set to short-circuit conditions continuously based on an electrical angle of the motor, and therefore a braking current as a generating source of braking force can be obtained and thus braking force can be secured. This braking force becomes variable by thinning off the phase intervals for short-circuiting the coils. Thus, stable braking force can be secured regardless of the simple control.

Title: Braking force distribution controlling method
Inventor: OSHIRO HIROSHI
IPC: B60T8/1764
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To properly perform the starting of a braking force distribution control by increasing a deceleration threshold according to lateral acceleration when a processing object is an outer wheel and decreasing the deceleration threshold when the processing object is an inner wheel and starting the braking force distribution control for a rear wheel when an absolute value of vehicle deceleration exceeds the deceleration threshold. SOLUTION: Whether a rear wheel of a processing object of a braking force distribution control is an outer wheel or an inner wheel is decided. Whether an absolute value of estimated deceleration is larger than a deceleration threshold or not is judged. When the absolute value is larger, whether a starting flag of the braking force distribution control for starting braking force distribution is set or whether a slip ratio is larger than a slip threshold or not is judged. The slip threshold is made a value that a correction value is added to a prescribed value in the case of the outer wheel and the slip threshold is made a value that the correction value is subtracted from the prescribed value in the case of the inner wheel. When the slip ratio is larger, the starting flag of the braking force distribution control is set to start the braking force distribution. As a result, the starting of the braking force distribution control can be exactly performed.

So air is replenished into the air tank 10 through the air piping 11. After then, when the prime mover 1 is operated, as the counterflow of air from the air tank 10 is hindered by the check valve 12, air in the air tank 10 is maintained. When surge pressure is generated in the return piping 7 under the condition, air in the air tank 10 is compressed to reduce surge pressure.
