Title: Flat type display
Inventor: FUNATSUKURI YASUO
IPC: H01J17/49
Filed: 1988-04-28
Abstract: PURPOSE:To facilitate the fabrication and reduce the power consumption by combining an electric discharge base plate provided with a large number of hollow electric discharge chambers with a control plate having many filamentary electrodes and aperture which are vertical to the electric discharge chambers. CONSTITUTION:An electric discharge base plate 11 is provided with a large number of recessed gas discharge chambers 4. When a pair of electric discharge electrodes 8, 81 in the respective electric discharge chambers is scanned to be connected with a DC power supply, these electric discharge chambers 4 get into discharge condition in sequential time-dividing relationship. When filamentary electrodes 6 orthogonal to a large number of the electric discharge chambers 4 of a control plate 5 combined with the electric discharge base plate 11 are driven sequentially in response to display information, in synchronization with the discharge conditions, electron beams go through apertures 51, 61 penetrating the control plate 5 and the filamentary electrodes 6 through accelerating electrodes 3 to radiate phosphor filaments 2 on the face plate 1. It is thus possible to align the apertures merely by upgrading the accuracy for fabricating the control plate 5 and these filamentary electrodes 6, then the fabrication of a display is facilitated and the power consumption is reduced because there is no necessity for always bringing one of these largely voluminal electric discharge chambers in a state of plasma.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To realize decorative or beautiful light by allowing light to cross a plurality of transmissive plates, and disposing a decoration at an radiating opening in such a manner that the transmissive plates are located substantially in parallel to a light projecting direction of the radiating opening. SOLUTION: Light is incident substantially perpendicularly to a transmissive plate 12 from a lamp 4 through a recess 18. Refracted light travels straight, and then, part of the light is reflected on a substantially S-shaped curve at the tip and side edges of the transmissive plate 12 while the residual light is refracted to be emitted outside, so that the emitted portion serves as a light emitting surface. Part of the reflected light is partly reflected at a cutout edge of a cutout 15 while the residual light is refracted to be emitted outside, so that the emitted portion serves as another light emitting surface. Part of the reflected light inside the transmissive plate 12 is gradually focused on a projection 20, and then, is emitted from the side and cutoff edges of the projection 20, so that the emitted portions serve as other light emitting surfaces. Consequently, it is possible to achieve an eye-catch effect of high brightness, thereby realizing decorative or beautiful light in the flourishing or gorgeous atmosphere.

IPC: H04N5/335
Filed: 1984-05-31
Abstract: PURPOSE:To reduce a device in size and power consumption by providing a multiplexer which inputs plural outputs of preamplifiers and outputs those inputs on time-division basis. CONSTITUTION:The preamplifiers QP1-QP3 are connected to plural signal readout lines EC1-EC3 led out of an array CA where charge implantation elements are arranged in a matrix. Outputs of those amplifiers QP1-QP3 are inputted to the multiplexer MP, which reads out the outputs of the amplifiers QP1-QP3 on time-division basis. Therefore, the device requires only one system of a readout circuit consisting of a main amplifier MA, sample and hold circuit SH, postamplifier PA, etc. Consequently, the area of the device is reduced to about one third as large as before as long as the number of readout lines is unchanged, and the power consumption is reduced greatly.

Abstract: PURPOSE:To prevent always effectively a damage to a supply water tank even when the water in the tank freezes by providing means by which a certain volume of air is always secured in the tank even if water more than a specified volume is poured into its inside. CONSTITUTION:When a supply water tank 7 is set to the main body 1 of a humidifier, the valve 9 in a cap 8 is pushed up by a shaft 12 to effect water supply. When in this state an ultrasonic vibration element 4 is driven by an amplifier for ultrasonic wave signal amplification, the water in the main body 1 is atomized and it is discharged from a discharge port 6 by the wind pressure of a blower 15. Further, when water is replenished by the supply water tank 7 itself, it is removed from the main body 1, the cap 8 is removed, and supply water tank is rolled over to supply water, but because there is an air tank 13 in the inside of the supply water tank 7, a space of air volume is secured in the inside of the supply water tank 7 even if the supply water tank 7 is full by pouring water into it. As a result, when the water 16 of maximum capacity is in the supply water tank 7 and the water freezes, the expansion of the volume by freezing is absorbed by the contraction of the air tank 13.

Title: Thickness detecting mechanism for paper sheet or the like
Inventor: HATA SHUICHI
IPC: B41J11/42
Filed: 1987-04-30
Abstract: PURPOSE:To prevent a sudden frictional force from acting on a paper sheet or the like at the time of an abnormality and prevent a jam phenomenon by rotating a detecting roller in synchronism with a transfer roller in a direction wherein the paper sheet or the like is carried. CONSTITUTION:When one paper sheet or the like 8 passes, a relationship between a gap G between a transfer roller 1 and a detecting roller 2 and the thickness (t) of the paper sheet or the like 8 is represented by G>t and no frictional force is produced at this time. The roller 2 is rotated in synchronism with the roller 1 via power transmitting means 20, an intermediate shaft 13 and a clutch 5. Therefore, the output signal of speed detecting means 10 has a normal time wavelength lambda1. However, when the two overlapping paper sheets or the like 8 pass, the relationship between the gap G and the thickness (t) is represented by G<2t to produce the frictional force. This generates a slip in the clutch 5 and reduces the rotational speed of the roller 2 and the wavelength lambda2 of the output signal of the means 10 is larger than the wavelength lambda1. Accordingly, no excessive external force acts on the paper sheets or the like 8 and no jam phenomenon is generated.
