Filed: 1988-07-20
Abstract: PURPOSE:To contract the area of table files and to reduce manual load by finding out numerical data relating to the 1st data name relating to the 2nd data name from the 1st and 2nd tables. CONSTITUTION:The 1st (2nd) table T1 (T2) stores a code D1 (D2) bit-allocated correspondingly to the 1st table name N1 (N2) and numerical data D2 (D1) annexed to the 1st (2nd) data name. The code D1 of the 2nd data name N2 is found out by referring the 2nd data name N2 in the 2nd table T2 and the 1st data name N1 is found out from the code D1. On the other hand, the data D2 annexed to the data name N1 is found out from the table T1. Since the data name N1 is controlled by the code bit-allocated correspondingly to the data name N1 and the number of data corresponding to the data name N1 is stored, the 1st data name relating to the 2nd data name and the number of data can be found out. Consequently, the data table can be contracted.

Title: Pwm inverter controller
Inventor: TOMITA HIROO
IPC: H02M7/48
Filed: 1983-09-29
Abstract: PURPOSE:To enable to PWM-control with good performance inexpensively by reading out a PWM pattern as a serial data from an ROM, and distributing it as 3-phase parallel data to the phases, thereby improving the utility rate of the ROM. CONSTITUTION:A voltage command data given to a multiplexer 5 selects the bit position of an ROM4, and produces only data corresponding to the desired output voltage pattern. The frequency command given to a rate multiplier 2 is altered in response to the output frequency of an inverter, thereby deciding the read-out speed of an ROM data. The PWM data stored in the ROM4 is read out at the speed proportional to the frequency of the inverter. When 3-bit data, i.e., the data of U, V and W phases are aligned in a 3-phase latch circuit 6, 3-phase PWM signals are outputted.

Filed: 1989-07-11
Abstract: PURPOSE:To eliminate the need of controlling focusing by obtaining a used beam whose intensity is high at a central part and whose intensity is low at the surrounding part and also forming a transparent member of a non-linear optical material whose refractive index changes corresponding to the intensity of the beam. CONSTITUTION:The transparent member 14 made of the non-linear material is loaded on the hole of a rotary drum 1, and a substance whose outgoing beam has Gaussian intensity distribution is used as a semiconductor laser 601'. When the laser beam having the Gaussian intensity distribution is made incident on the transparent member 14 after the laser beam is converted to the collimated beam of light by a collimator lens 603, the refractive index of the transparent member 14 becomes large distribution at the central part of a beam incident part and becomes small distribution at the surrounding part of the beam incident part. Then, lens effect is generated in the transparent member 14 and the, the beam is focused and also the reflected beam goes in the opposite direction in the transparent member 14 in the state of being converged. Thus, the need of controlling the focusing can be eliminated.

IPC: G02F1/1335
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a projection display device in which there is not irregularity in color and brightness, a uniform contrast ratio and high-quality display throughout the entire screen by the use of effectively arranging lenses. SOLUTION: An intermediate lens 8 is situated in the middle position of the optical path between an optical integrator 2 and reflection type liquid crystal panels 11, 12, 13 to convert the divergent light from the optical integrator 2 to parallel luminous flux. Parallel luminous flux passes a polarized light beam splitter 9 and a dichroic prism 10 and the principal rays of the luminous flux incident on each display surface of the reflective liquid crystal panels 11, 12, 13 are perpendicular to the surface of the liquid crystal panels. Reflection passes the dichroic prism 10 and the polarized light beam splitter 9 as a parallel light beam. A telecentric optical system is used for the projection lens 14.  By this, since no irregularity in color and contrast due to the angular dependence of the dichroic prism 10 and the polarized light beam splitter 9 is generated, a bright, high-quality display uniform in image quality is realized.
