Title: Automatic release card reader system
Inventor: MATSUMOTO YASUO
IPC: G06F3/06
Filed: 1987-05-28
Abstract: PURPOSE:To automatically restart a card reader, by sending a reset signal for restart of the card reader when a prescribed time elapses after reception of the last unit recognition signal. CONSTITUTION:A timer 19 of a higher controller 12 is started at each time of reception of the unit recognition signal; but when some time elapses after the unit recognition number signal breaks, that is, when a prescribed (second) time longer than a prescribed (first) time elapses after reception of the last unit recognition number signal, the timer 19 expires. Consequently, the timer 19 expires and a reset signal generating circuit 20 sends the reset signal to a reset signal line 14 if the unit recognition number signal is not sent to the higher controller 12 because a card reader body 15 cannot be operated by noise. Thus, a card reader 11 is automatically released by the reset signal from the higher device, and abnormality of the card reader 11 is prevented from causing system down, and it is automatically released by the higher device 12.

Title: Color filter and liquid crystal display device using the same
Inventor: ONISHI HIROYUKI
IPC: G02F1/13357
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To improve the light transmittance of a color filter. SOLUTION: In a color filter CF1 , diffusion plate 4 and a filter part 6 are arranged with a glass substrate 5 inbetween. Dichric mirrors 6a, 6b, and 6c constituting the filter part 6 allow only light of different specific wavelength areas to pass through an reflect light of other wavelength areas. When light is made incident on the dichroic mirror 6a from a light source part LS, only red light, for instance, is transmitted through but other (green and blue) light is reflected. Reflected light is diffused and reflected by the diffusion plate 4 and is made incident on the dichroic mirror 6b, and only green light is transmitted, and other blue light is reflected. This blue light is diffused and reflected by the diffusion plate 4 and is made incident on the dichroic mirror 6c and is transmitted.  Since light reflected by each dichroic mirror is diffused and reflected by the diffusion plate 4 and is transmitted through another dichroic mirror, the transmittance is improved.
