Title: Spatial optical modulator, automatic stereoscopic display and back light as well as production of spatial optical modulator
Inventor: GURAHAMU JIEI UTSUDOGEETO
IPC: G02B30/27
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal spatial optical modulator suitable for use in an automatic stereoscopic display by extending the columns of pixel apertures substantially perpendicularly to a prescribed direction and making the columns of respective sections substantially continuous. SOLUTION: The apertures for active pixels of a mask 2 are not substantially superposed on each other in a horizontal direction but are so corrected as to be arranged in a substantially continuous column form. Namely, the columns of the apertures are so arranged that the parts connected with the black mask 2 perpendicular without disconnection are minimized or do not exist at all between the adjacent columns of the apertures of the corrected mask 2. More particularly, the partial degradation in the strength occurring in the angles of the apertures is compensated when the angles are slightly rounded in the actual production of the black mask 2 and, therefore, the slight superposition of the apertures of the black mask 2 on each other is possible.  The LCD similar to the LCD of the conventional type except that the LCD is suitable for use in the automatic stereoscopic display is produced by using such black mask 2.

Title: Control method for meter by microcomputer
Inventor: HIROYASU YOSHIHISA
IPC: G01P1/07
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To obtain a control method in which the responsivity of a measuring- instrument pointer is increased in a speed decreasing region/an engine-speed decreasing region by a method wherein the time elapsed at a cycle which is longer than that of the previous measured value of an input pulse is used as cycle data so as to be converted into the value of a deflection angle and the value is averaged and processed. SOLUTION: A cycle measuring block to which pulses SP, TA at frequencies according to a vehicle speed and to an engine speed are input counts the number of rise edges per gate time of every input pulse, and it measures the time elapsed up to the last from the front. In parallel with the measurement of a cycle, the time elapsed from an edge detection is monitored by a low-vehicle-speed judgment/low-rotation judgment block, and the time elapsed at a cycle which is longer than that of a previous measured value is used as cycle data. After that, the cycle data is converted into a deflection angle at a constant interval by a deflection-angle conversion block, it is averaged and processed, and the behavior of a pointer is stabilized.  In addition, a correction is performed by taking into consideration the pointer characteristic of a meter so as to be converted into serial data on a meter driver. Thereby, the meter can be controlled with good responsivity even when an input pulse frequency is lowered.
