Title: Reflection type liquid crystal display element and liquid crystal projector
Inventor: HIROTA SHOICHI
IPC: G02F1/136
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to embody a high light utilization efficiency and high contrast ratio by specifying the product of the thickness and refractive index anisotropy of a phase plate nearly to half the central wavelength of incident light. SOLUTION: The refractive index anisotropy of the phase plate 14 is expressed as Dn PH and the layer thickness thereof as dPH. The relation between the sum Ir of the intensity of the boundary reflected light generated between the phase plate 14 and a liquid crystal layer 8, the retardation (dPH×Dn PH) of the phase plate 14 and the light intensity I0 superposed on image light is expressed like the equation; I0 =Ir Tp Sin<2> (2πdPH×Dn PH/λ). In order to minimize I0 , dPH×Dn PH is merely necessitated to be set at λ/2. Then, the value of the retardation of the phase plate 14 is set at the value of nearly half the central wavelength of the incident light which is made incident on the liquid crystal display element. Namely, the phase plate 14 has a function as a half-wave plate.  The phase plate 14 is formed by holding a phase film with two sheets of glass substrates to prevent the change in the retardation of the phase film by the strain and stress occurring in heat, etc.

Title: Flash photographing device
Inventor: KOTO ETSURO
IPC: G03B15/05
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To reduce a change in the quantity of light on an image surface and to automatically switch flash lighting control and intermittent lighting control by varying the peak value of flash light by a prescribed value, when it is switched from the intermittent lighting control to the flash lighting control. SOLUTION: When a low-speed side shutter speed instruction is issued, as flashing setting processing, a microcomputer 12 sets the flash light wave height value at a 1/4 maximum flash light wave height value and outputs it to a flashing controller 19. On the other hands, when a high-speed side shutter speed instruction is issued, as FP flashing processing, the microcomputer 12 sets the flash light wave height value at a maximum flash light wave height value and outputs it to the flashing controller 19. Thus, in the case of flash- photographing, FP flashing is automatically separated from flashing by a shutter speed and a wave height value is changed to a fixed one as well, so that each prescribed timing flashing processing is carried out.  In a shutter speed area where the flashing and FP flashing are switched, a drastic change in the quantity of the light in the image surface is improved and smooth switching can be attained.

Filed: 1994-09-20
Abstract: PURPOSE: To make it possible to avoid danger that a hand may be clamped between horizontal sash bars by shortening the length of a support from an extended state and venting air prevailing in the support gradually and lowering an upper horizontal sash bar slowly. CONSTITUTION: When a ladder is shortened so as to house, an operation part of a lower most member 2a is pushed up and a locked second member 2b from the bottom is released so that it may fall down with the other locked member above the member 2b.Then, the volume of a post 4 is reduced so that the inside air may be vented gradually upward by way of cuts 41, thereby slowing down the falling speed. Then, a horizontal sash bar 6 of the second member 2a comes into contact with a horizontal sash bar 6 in the lower most part, which releases the locking of the third member 2c from the bottom and vents the air and lowers the member 2c and the upper member at a low speed. When the member 2b directly above the bottom by one step falls down, the horizontal sash bar 6 comes into contact with a stopper and comes to a halt, thereby preventing a hand from being clamped in between.
