Filed: 1993-12-16
Abstract: PURPOSE:To suppress the decrease in the light quantity of a back light source, to improve the way of looking of interference fringes and to provide a device which is bright and has an excellent display grade by forming transparent electrodes and insulating film to film thicknesses of low reflectivity to one specific bright line of the back light source and making the half-amplitude value of the bright line exclusive a specific bright line wide in the wavelength distribusion of the back light source. CONSTITUTION:The transparent electrodes 12, 22 and insulating films 13, 23 on transparent substrates 11, 21 constituting a liquid crystal panel are formed at the film thicknesses of the low reflectivity to the one specific bright line of the back light source. The back light source is widened in the half-amplitude value of the bright lines exclusive of the specific bright line in a wavelength distribution. As a result, the specific bright line has high transmittance, increases the luminance of the panel and weakens the interference fringes by reflected light which is of a problem particularly with the steep bright lines. In addition, the bright lines exclusive of the specific bright line have a possibility that the reflectivity at the surfaces of the transparent electrodes 12, 22 and the insulating films 13, 23 increase slightly but the half-amplitude value thereof is set wide and the broad bright lines are set and, therefore, the interference fringes by the bright line are weakened and are made hardly visible.

Algae floating on the water surface of the reservoir are allowed to flow to the inlet from water surface flow C generated by wind directed to the inlet. However, algae do not approach the inlet because the water surface flow C is carried back by the horizontal flow A.

Title: Image forming device
Inventor: TOMITA KUNIHIKO
IPC: G03G15/08
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent image staining and blur which are caused especially by a replenishing roller, in a one-component-toner development system using the replenishing roller. SOLUTION: The device is equipped with a latent image carrier 1 on which an electrostatic latent image is formed, a developing roller 5 for developing the electrostatic latent image on the electrostatic latent image carrier 1 with one-component toner, and the replenishing roller 6, composed of a metal roller, for adding the one-component toner onto the developing roller 5 in press-contact with the developing roller 5. Because adhesion in an interface between the metal and resin is considerably weak, wear and picking force between the rollers 5 and 6 do not increase, and the surfaces of the rollers 5 and 6 do not wear easily even if they are rubbed against each other with a difference in peripheral speed between them.  Also, because a change in the resistance value of the replenishing roller 6 does not occur, toner electrification can be kept uniform, and staining and blur can be prevented.

Title: Multiple address communication system
Inventor: SUGITA MITSURU
IPC: H04L12/42
Filed: 1989-12-29
Abstract: PURPOSE:To warrant multiple address performance of multiple address communication by adding a reception disable flag to a frame of multiple address communication and circulating the resulting frame so as to detect mis-reception of the multiple address communication thereby applying retransmission processing. CONSTITUTION:When a reception buffer 14 is busy and reception is disabled, a busy signal is outputted to a buffer busy register 15 and a multiple address communication detection circuit 13 uses the output to command to a reception disable flag set circuit 16 to set the reception disable flag. The reception disable flag set circuit 16 sets a frame status(FS) flag. A node station sending the multiple address communication observes a frame set from itself returned throughout a transmission line 2 and when the reception disable flag is set, the presence of the node station whose reception is disabled is recognized. Thus, the multiple address performance of the multiple address communication is warranted by retransmission.

Title: Within-bed pressure detector for pressurized fluidized bed boiler
Inventor: OHASHI HIROYASU
IPC: F23C10/16
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To diffuse bed material and ash to a pressure vessel at the time of generating trip, and to prevent clogging of the material to an inner outlet and an outer pressure extracting tube by allowing suction of the air from a suction vessel into the discharge tube and preventing injection of gas into the pressure extracting tube. SOLUTION: When pressure of a fluidized bed boiler 2 becomes higher than that in a pressure vessel 1, a spherical valve 33 of a check valve 30 is urged to a valve seat 32 so that backflow of gas in the boiler 2 into a pressure extracting part 19 is prevented, and hence injection of gas containing bed material 4 and ash into the vessel 1 is prevented. Even if pressure is reversed in the part 19 of a lowermost stage provided at a position where an inner outlet 24 is embedded in the material 4 dropped and deposited due to generation of a trip, the deposited material 4 is not intruded into the part 19 by an operation of the valve 30, thereby preventing clogging of the material 4 in the outlet 24 and an outer pressure extracting tube 23.
