Title: Light diffusing sheet and reflection liquid crystal display device using the same
Inventor: MIZOBUCHI TAKASHI
IPC: G02B5/32
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To emit a large quantity of display light to an observation position and to realize bright, high-contrast and high-definition display by providing a function that transmitted light is diffused while it is condensed in a specified range. SOLUTION: The light 5 transmitted through the light diffusing sheet 4 and made incident from the front surface of a liquid crystal panel 2 is transmitted through the sheet 4 without being diffused, and is reflected by a reflector 3. The light 6 transmitted through the sheet 4 and emitted from the front surface of the panel 2 is optically diffused like the case that it is transmitted through the sheet 4 being a light transmissive one (or on the contrary it is diffused and transmitted when it is made incident and it is only transmitted when it is emitted), and is emitted as the light diffused while being condensed in a range where a display screen is observed.  Therefore, unnecessary display light is not diffused, the display gets bright and the light is diffused only when the light is emitted (or made incident), so that the high-definition display where a phenomenon such as image deviation, double pixel and the blotting of the pixel does not occur in a display picture observed from the front surface of the panel 2 is realized.

Title: Inductively coupled plasma emission spectrochemical analyzing apparatus
Inventor: ITOU TETSUMASA
IPC: G01N21/73
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To maintain a positional relationship constant even when a force is applied to a torch by setting a torch branch pipe clip which enables a torch branch pipe to be fitted by rotating the torch centering a center axis of the torch. SOLUTION: The inductively coupled plasma emission spectrochemical analyzing apparatus is provided with a torch branch pipe clip 9 for holding, e.g. a plasma gas feed pipe 10 of a torch 12. A gap of the torch branch pipe clip 9 has an equal size to an outer diameter of the plasma gas feed pipe 10. The plasma gas feed branch pipe 10 is fitted by rotating the torch 12 about a center axis of the torch after setting the torch to a torch-fixing tool 7. The fixed torch 12 is accordingly prevented from moving back and forth in a direction of the center axis. A positional relationship in the direction of the center axis between an XYZ stage 14 and the torch 12 is kept constant.  Unless a position of the XYZ stage 14 changes, a positional relationship between a plasma 2 formed to a leading end of the torch 12 and a sampling cone 1 or the like is constant at all times, and therefore measurement results of good reproducibility can be obtained.

Abstract: PURPOSE:To obtain a stable copy image of high quality by providing an isolating plate consisting of a fixing guide into two at least so that the potential generated in a pressuring roller of a fixer and heat of a fixing device have no influences upon a transfer paper after transfering. CONSTITUTION:A toner image on a photosensitive body is transferred to a transfer paper 2 indicated by a dash line, and the transfer paper 2 reaches a roller 1b following up the photosensitive body and is separated from the photosensitive body forcibly with a separating claw 5 by a mechanical method and is guided by fixing guide and reaches an isolating plate 8. At this time, a heating roller 6a and a pressuring roller 6b of a fixer 6 are pressed to each other and rotated, and >=-2kV potential is generated on the surface of a silicone rubber of the pressuring roller 1b by frictional charging; however, the transfer paper 2 is guide by the isolating plate 8 and is fixed and ejected because the isolating plate 8 is arranged near the part where the heating roller 6a and the pressuring roll 6b are pressed to each other, and thus, copy images without image blurring are always obtained stably. Since the fixing guide and the isolating plate are divided into two, heat of the fixing device is not directly conduct to the photosensitive body, and the photosensitive body is not damaged.
