Abstract: PROBLEM TO BE SOLVED: To obtain a high-performance surface acoustic wave element by finding cut faces and the surface acoustic wave propagating direction which are more appropriate than the conventional ones in a lithium niobate substrate and a lithium tantalate substrate. SOLUTION: The cut face and the surface acoustic wave propagating direction of a lithium niobate piezoelectric substrate on which electrodes are formed for propagating surface acoustic waves are setin Euler angle representation (ϕ, θ, ψ) and the conditions 0 deg.<=ϕ<=86 deg., 73 deg.<=θ<=118 deg., and 0 deg.<=ψ<=44 deg. within substantially equivalent ranges thereto. Therefore, the propagation loss can be reduced to <=0.05dB/λwithout deteriorating the phase velocity and electromechanic coupling factor.  In addition, by setting the cut face and the surface acoustic wave propagating direction of a lithium tantalate piezoelertic substrate can be reduced to <=0.005dB/λ without deteriorating the phase velocity and the electromechanic coupling factor to (ϕ, θ, ψ) in Euler angle representation and 0 deg.<=ϕ<=87 deg., 80 deg.<=θ<=120 deg., and 0 deg.<=ψ<=44 deg. within substantially equivalent ranges thereto.

Title: Scum removing device
Inventor: FUJIWARA MITSUHIRO
IPC: B01D21/24
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To lightly drive a weir without being affected by water pressure when removing and recovering scum floating on the surface of the water in a sedimentation basin or the like by forming a weir for opening and closing an opening of a trough into the shape provided with an introducing path in which a part of a cylindrical body is cut off to form and supporting it rotatably back and forth. SOLUTION: By driving a flight 5 in the direction of the arrow, scum on the surface of the water 1 is raked up toward a scum removing device, and by pushing up a copying cam 29 by a roller 28 fitted to the flight 5, an operating arm 30 is lifted on the forward side thereof and is lowered on the rear end side. Then the weir 16 is rotated through an interlocking rod 35 and an interlocking link 26 with its front coming down too low. In this way, since a sheeting 19 which has regulated the scum on the surface of the water being swallowed up is gradually lowered with the rotation of the weir 16, the scum flows into the trough 12 and flows into the next trough through a communicative trough, and flows through the successive communicative troughs and troughs and finally flows into a scum pit and is transferred to the next treating process.

Abstract: PURPOSE:To simplify data handling and speed up data access by providing plural computers with means which output plural data in predetermined order and providing a request data extracting means. CONSTITUTION:When data 13 outputted from a computer 3 for transmission are uploaded to a high-order network 5, the output order of, for example, the temperature A, pressure B, and flow rate C of steam is predetermined and the data are outputted in this order.

Title: Color video signal processing circuit
Inventor: OKADA HIROSHI
IPC: H04N9/87
Filed: 1988-03-09
Abstract: PURPOSE:To read out screen information in which a color sequence is always continuous between fields by detecting whether the number of recording lines in a field memory is an odd number or an even number, and executing a control so that the number of read-out lines of the next field becomes an even number substantially, in case the number of said recording lines is an odd number. CONSTITUTION:In field memories 28 (A, B and C), an H end code is added to its last position at every line period corresponding section, and to the last data of a final horizontal line of a field period V end code is added. Therefore, when these H end code and V end code are detected by a read-out address control part 50, and reset is applied to a horizontal address counter 33A and a vertical address counter, the number of data of the section corresponding to the line period is fluctuated due to variable speed reproduction, etc. Also, even if the number of lines itself of reproduced video data is varied, the continuity of a subcarrier is held, and also, in one field, video data in which a color sequence is correct can be read out.

IPC: G09G3/28
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent a change in a voltage drop in a line electrode, and perform stable display operation by generating a control signal corresponding to a brightness level, and controlling voltage of a line electrode driving pulse according to this control signal. SOLUTION: A brightness level detecting circuit 7 counts the number of light emitting picture elements on the basis of picture element data equivalent to a single frame or equivalent to a single sub-field, and detects an average brightness level by its value, and supplies an average brightness level detecting signal to a controller 8. The controller 8 supplies a voltage control signal to control voltage of a maintaining pulse to a line electrode driving pulse generating circuit 13 in response to an average brightness level detecting signal or an electric current level detecting signal. In this way, nonuniformity of display brightness by a change in a voltage drop in a line electrode is prevented by using a signal corresponding to a brightness level as a control signal, and stable display operation can be performed.

Filed: 1993-03-15
Abstract: PURPOSE:To simplify of a configuration controller, to facilitate the control and to realize a far and near sense by one system circuit by controlling a sense of distance through the use of an sense characteristic of a human being. CONSTITUTION:A white level noise from a sound source 11 becomes a band noise via a BPF 12 and fed to an amplifier 13, and reproduced at a speaker 14. A center frequency of the BPF 12 is changed to evaluate a psychological distance sense of a sound image of the reproduction sound at every center frequency of the BPF 12. When a pass band of the BPF 12 is set to a specific frequency (6kHz-10kHz), a listener 15 feels a sound image to be smaller than an actual distance such as 1m or below. Thus, the characteristic of a sense of human being is utilized to emphasize or attenuate the band of the center frequency of 6kHz-10kHz thereby controlling a sense of psychological distance.

Abstract: PURPOSE:To improve the yield of products by providing on MISFET and depletion type MISFET whose source and drain are connected in common and by obtaining a constant current from the drain of this MISFET. CONSTITUTION:While beta of MISFET Q1 is set greater than that of MISFET Q2, prescribed power voltages VDD and VSS are applied to circuit terminals T1 and T2, so that a bias voltage nearly equal to threshold voltage VthE of FET Q1 is obtained from the common-connected gate and source on the basis of power voltage VSS. To the gate of depletion type MISFET Q5 whose source is connected to circuit terminal T2, the bias voltage is applied to obtain constant output current I0 from circuit terminal T3 to which the drain of FET Q5 is connected. Thus, a differential amplifying circuit having reduced variance in gain is obtained to improve the yield of products.

IPC: G06F3/12
Filed: 1992-02-05
Abstract: PURPOSE:To automatically implement proper initial setting to each district or each country by implementing the initial setting based on information of a detection means detecting a power supply voltage. CONSTITUTION:When power is applied to a laser beam printer, an MPU 36 detects the power supply voltage from digital data from an A/D converter 35 and when the detected value is less than 110V, it is discriminated the district to be a power supply voltage 100V, that is, Japan and the initial setting of paper size is set to be size A4. When the detected voltage is in a range of 110-140V, it is discriminated that the power supply voltage is 120V, that is, the USA, and the initial setting of paper size is set to a letter size. Furthermore, when the voltage is other than the power supply voltages (more than 140V), it is discriminated that the power supply voltage is within a range of 200-220V, that is, Europe, the initial setting of paper size is set to be size A4. In this case, the recorder allows an external device to select the initial setting corresponding to the power supply voltage by transferring each detection information or identification information to the external device.
