Title: Light transmission plate
Inventor: YAMAMOTO NAOAKI
IPC: G02F1/1335
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a diffusion sheet without degrading the brightness of a liquid crystal display, to lessen unequal luminance and to obtain a diffusion effect by imparting changes in surface shapes to the rear surface of a light transmission plate and constituting the light transmission plate by incorporating and dispersing the particles of a specific transparent high polymer into a transparent resin. SOLUTION: The periodic changes in the surface shapes with which the incident light from a light source L is reflected and refracted are imparted nearly over the entire area of the rear surface of the light transmission plate P. The light transmission plate P is constituted by incorporating and dispersing the particles of the transparent high polymer having the refractive index different from the refractive index of the transparent resin into the transparent resin at 0.05 to 30wt.%. The light reflected and refracted by the periodic changes in the surface shapes is further diffused by the particles at the time the light is transmitted in the light transmission plate P. The light is emitted with a bright and natural feel from the front surface of the light transmission plate P.  Then, the unequal light emission from the light transmission plate P is sufficiently suppressed without the need for using the diffusion sheet.

Abstract: PURPOSE:To adjust a damping force corresponding to a running condition of a vehicle by rotating a control rod mechanically corresponding to a steering angle in steering operation. CONSTITUTION:An L-shaped connection bracket 41 is integrally formed on the outer circumferential side of an upper sheet 16 fixed to a cover part of an upper side spring bearing 15, and an upper side of a control rod 43 is installed to an installation hole 41C of the connection bracket 41 to be prevented from rotating.

Title: Clutch on-and-off apparatus
Inventor: YAMADA TADAHARU
IPC: F16D48/00
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent bubble mixture in an oil pressure path and perform an accurate manual operation in an automatic clutch turning-off operation by giving air pressure to the rear face side of a piston in a master cylinder to pressurize the interior of the oil pressure path. SOLUTION: A controller 72 turns ON or opens both changeover valves 78, 79 according to the input of a speed change signal in the speed change to supply air pressure from an air pressure supply path (a) to a booster device 7. On the other hand, air pressure is supplied through an air pressure piping 62 to the rear face side of a piston 48 in a master cylinder 10 to properly movably press the piston 48 and pressurize the interior of an oil pressure path 54. Also, in the automatic clutch turning- off operation before the operation of the changeover valves 78, 79, a changeover valve 81 is opened somewhat earlier to give proper initial pressure.  On the other hand, in the automatic turning-on operation of the clutch 8, air pressure at the rear face side of the piston 48 is properly relieved to the atmosphere from the changeover valve 81 in response to the sequential pressure increase in the oil pressure path 54. Also then, the changeover valve 81 is closed later after the operation of the changeover valves 78, 79 to give the air pressure up to the last, so that the generation of negative pressure can be completely prevented.

Title: Image reader
Inventor: YAMAMOTO YASUHIRO
IPC: H04N1/405
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To perform highly accurate color correction by obtaining a highly accurate color correction parameter prior to the color correction performed accompanying negative/positive conversion. SOLUTION: Exposure measurement is performed for each image of a negative film (110). Image signals are coarsely read for color correction parameter calculation in coarse scanning and the histogram of the image signals is prepared (120). The maximum value of the histograms for respective colors R, G and B is obtained (130) and then, a minimum value is obtained (133). When pre-scanning (140) is ended, an operator judges whether or not to start main scanning. At the time of performing the main scanning, the image signals are detected, turned to a digital image signal level, color-corrected and negative/ positive converted and thus, normalized data are obtained (160).  Since the color correction parameter is calculated from the maximum and minimum effective values and the distribution width of the histogram is enlarged by the color correction, the accuracy of the color correction parameter is improved and the highly accurate color correction is made possible.

Title: Line connecting system
Inventor: NAGASHIMA NORIAKI
IPC: H04B7/26
Filed: 1988-07-14
Abstract: PURPOSE:To decrease the load of a radio control channel by trying incoming call with successively ascending to a registering position in past when the incoming call to a radio telephone set can not be executed in the latest registering position in a radio telephone system. CONSTITUTION:When the incoming call from a fixed network NW1 to a radio telephone set RT4a, for example, is detected, a line connecting equipment LCU2 refers a position information storing table PTL and selects an RCE3a, for example, of the address 1 of the RT4a. Then, the incoming call to the RT4a is instructed. The RCE3a calls the RT4a with an outgoing radio control channel and waits for a response. When any response is not given from the RT4a, the RT4a sends an incoming call no-response signal to the LCU2. Until an incoming call response signal is obtained, the LCU2 successively refers the address of the RT4a in a PTL26 and selects the RCE. Then, the instruction of the incoming call is repeated. When any response is not given even in such a step, the instruction of simultaneous incoming call is executed to all RCEs 3a-3j. Thus, all radio areas are not simultaneously used immediately and the load of the radio control channel is decreased.
