Title: Diaphragm for speaker
Inventor: HIGAKI TAKASHI
IPC: H04R7/08
Filed: 1980-06-06
Abstract: PURPOSE:To accomplish a speaker larger in piston region of an audio frequency characteristic, smooth in high tone band and less in sound distortion, by filling in a resonance damping member in a cavity of a unit core group of a part of axial symmetrical oscillation node of a diaphragm plate of honey-comb construction. CONSTITUTION:Thin plates 16, 18 are bonded on both the surfaces of a honey- comb core 12 consisting of a number of unit cores 14 to form a cone type or plane shape diaphragm plate 22. Taking the length from the center to the end as (a), in a ring shape core group, e.g., 3cm wide, around the node of the 1st order axial symmetrical split oscillation, 0.68a from the center, a resonance damping member 20 such as soft urethane foam is filled. Thus, while keeping a high elasticity versus density ratio (E/rho) and increasing the coefficient of loss (tandelta), a diaphragm plate in which the piston region at the sound pressure frequency characteristic is increased, the split oscillation region (high tone area) is comparatively smooth, and distorted tone is less, can be accomplished.

Title: Image forming device
Inventor: MURAYAMA YASUSHI
IPC: G03G15/04
Filed: 1988-03-31
Abstract: PURPOSE:To prevent color slippage by limiting correction processing to each image carrier based on color used information, performing correcting only the image carrier corresponding to used color, stopping the correction to the image carrier corresponding to unused color, and stopping the overall correction to the image carrier when the used color information specifies monochrome usage. CONSTITUTION:A controller 13 serves as a correcting means and a correction limiting means. For example, when any two specified colors out of four colors are inputted as the information, only an image on an image forming station corresponding to the information is corrected, and correction of image forming stations corresponding to unused color is stopped. When the inputted information specifies monochrome, correction is overall stopped. Thus the time for adjusting color slippage can be shortened, and simultaneously images of required color can be overlapped at high accuracy.

Title: Secondary current suppressing circuit of wound-rotor type induction motor
Inventor: YAMAGUCHI KATSUKI
IPC: H02P1/36
Filed: 1984-04-18
Abstract: PURPOSE:To reduce the cost by starting an induction motor with a liquid resistor connected at the secondary side and inserting a reactor before shortcircuiting the secondary side, thereby simplifying the construction. CONSTITUTION:A motor 1 is started by a liquid resistor 5 connected with the secondary side, a switch 11 is closed when electrodes 6 become a minimum gap to connect a reactor 10 with the secondary circuit of a motor. A rush current when the switch 11 is closed is suppressed by a reactance component to accelerate the motor 1, and when approaching a rated speed, the frequency of the secondary current of the motor decreases. Accordingly, the impedance due to the reactance becomes of the degree to be ignored. Then, the secondary shortcircuiting unit 2 is connected. Thus, the secondary current can be suppressed with a simple circuit configuration.

Abstract: PURPOSE:To reduce the tap switching frequency as much as possible by clearing an undesired integration of th deviation between a target voltage and an actual voltage at every predetermined time in the on-load tap changer which adjusts the secondary voltage of a power rceiving transformer in a power receiving equipment. CONSTITUTION:In the on-load tap changer which adjusts the secondary voltage of a power receiving transformer, the deviation between a target voltaage Vv and an actual voltage V is calculated by a comparator 8, and a blind sector setter 9 outputs a switching signal for constant or more voltage fluctuation, and this output is integrated by an intergrator consisting of an amplifier 10, an input resistor 11, and a capacitor 12; and if this integrated value becomes a constant value, a rise command detector 16 is operated and drives a relay 17 to cause the voltage to fall. When the switching signal is outputted, the contact for reset of the integrating capacitor 12 is closed by a switching completion switch 3 to clear the integral result. Two timers 19 and 20 are operated at every constant time, and integration is reset by a contact 18 of the timwr 19, and thus, the tap is prevented from being switched due to long- time integration in case that the voltage is fluctuated near the target value.

Abstract: PURPOSE:To display a number of images by determining a presence and data changing with time of a display loaded into a memory element of a plurality of display memories as control code to keep new and old information with a limited number of display memories. CONSTITUTION:An image data signal (a) is inputted into a display data control section 11 at a fixed time interval with a bow line signal (i) as reference. When an erasion mode is set from a display mode M, a control code (B1B2) to be outputted from a system control section 12 turns to a code changing with time if the signal (a) is 1 to be written as intact. If the signal (a) is zero, an old image 19 preceding four times is erased from a display screen 18 when a data code (E1E2) of display memories 14a and 14b coincides with the code (B1B2) so that the screen is made easy to view thereby allowing the determination of moving direction and a speed of a target. When they do not coincide, display state remains unchanged. Then, when a continuous display mode is set, the secular code (B1B2) is written if the signal (a) is 1 and an old image 19 is displayed as intact if the signal (a) is zero. Thus, if a mode is set properly, a moving locus of the target can be displayed.
