Title: Holographic head-up display
Inventor: SATO ATSUSHI
IPC: B60K35/00
Filed: 1995-04-14
Abstract: PURPOSE: To increase the utilization efficiency of the quantity of light from a light source, to apparently increase the size of the light source and increase the degree of freedom of an optical system, and to decrease the number of constituent components and lower the cost by interposing a holographic diffusion plate between an information display device and the light source. CONSTITUTION: The holographic diffusion plate 1 is provided between the liquid crystal display panel 2a and light source 3. The light emitted by the light source 3 is diffracted by the holographic diffusion plate 1, converted into lights from many spot light sources having a necessary spread angle, and they are made incident on the liquid crystal display panel 2a. The set of the spot light sources generated by the holographic diffusion plate 1 is masked with image information by the liquid crystal display panel 2a and made incident on the side of a holographic combiner 4. Therefore, a bright light which is oriented to some extent is made incident on the side of a driver 9, from which a virtual image 8 of the information pattern on the relatively bright liquid crystal display panel 2a can be observed. Further, a visual area 10 having some extent is formed on the side of the driver 9.

Title: Data transfer system
Inventor: NOGUCHI HIROYUKI
IPC: H04L25/02
Filed: 1981-06-09
Abstract: PURPOSE:To transfer a data in a short time with a small number of information transfer leads, by dividing the information composed of plural bits and feeding them simultaneously onto plural information transfer leads after converting them into the series information. CONSTITUTION:The n-bit data D1-Dn are divided into bits D1-Dm and bits Dm+1-Dn by the control of a control circuit CONT and then converted into the series data by the parallel-series converting circuits P-SCON0 and P-SCON1 to be transmitted to the transfer leads DL0 and DL1 through an information transmitter EQ0. While an information receiver EQ1 receives the information and feeds the information to the circuits S-PCON0 and S-PCON1 to convert them into the parallel information D1-Dm and Dm+1-Dn. The converted parallel information is stored in a storing circuit REG. Thus the number of information transfer leads is decreased compared with a system in which all data are transferred in the form of the parallel data. In addition, the transfer time is also decreased compared with the transfer with all-bit series information.
