Title: Large screen display device
Inventor: SAKAI YUICHI
IPC: G09F9/33
Filed: 1992-01-08
Abstract: PURPOSE:To emit light even at a display joining part in the case that tiling is executed by refracting the light emitted from respective light emitting points by the curved surface of a front panel and making the apparent light emitting point on a side plate provided around the front panel. CONSTITUTION:A display element is a cathode ray tube and the light is emitted by accelerating an electron generated by a heater or the radiation of an electric field by a high voltage and making it collides with a light emitting surface formed on the back surface of the front panel 14. In such a case, since the surface of the panel 14 is curved, the light seems to be emitted from some part of the side plate 4 around the panel 14 because of the action of the curved surface when it is viewed from the front. That means, since the light 17a emitted in a front direction among the light emitted from the light emitting point 16 is passed through the chamfer 18 of the panel 14, it is not refracted and advanced forward. Since the light emitted from the point 16 and advanced forward is the light which is obliquely emitted, it is refracted by the chamfer 18 and advanced forward. Then, the point 16 seems to be entirely positioned at the front part of the side plate 4.

Title: Spherical end mill
Inventor: HAYAMA TAKAMICHI
IPC: B23C5/10
Filed: 1981-02-10
Abstract: PURPOSE:To cut a finished surface well with a spherical end mill so that the cut surface is not deteriorated by the deflection and chatter of the end mill, by  providing the spherical end mill with cutting portions different from each other  in the direction of twisting. CONSTITUTION:The first cutting portion 4 of a spherical end mill is a rightward oblique cutting portion having an arc-shaped cuttig edge 7 on the central part. The second cutting portion 5 of the end mill is a leftward oblique cutting portion having no cutting edge on the central part. The first and the second cutting portions 4, 5 are secured on the body 1 of the end mill by brazing. When the spherical end mill is rotated rightward for cutting, the cutting resistance to the leftward-twisted cutting edge 4 acts toward the shank of the mill and the cutting resistance to the rightward-twisted cutting edge 5 acts oppositely to the shank so that the cutting forces of the edges cancel each other in the cutting rotation. For that reason, the end mill is not deflected and performs no chatter. Therefore, a finished surface is cut with high accuracy.

Abstract: PURPOSE:To control damping force, and to suppress the vibration of a car body with good response by controlling the damping force to a smaller level at the time of excitation, while to a larger level at the time of damping, based on the direction of a damping force calculated from a rate of damping force change as well as of spring upper acceleration. CONSTITUTION:The generation pattern of the damping force at a shock absorber SA provided between a wheel WH and a car body US is controlled, and the vibration of a car is suppressed. A rate of damping force change at the shock absorber SA is detected by a damping force rate of change detection means M1.

Vertical acceleration of the car body is detected by a spring upper acceleration detection means M3. When the direction of the estimated damping force and that of the detected acceleration are identical, the damping force of the shock absorber SA is controlled to be lower level, while higher level on the contrary occasion, by a damping force controller M4.

The channel under inputting gate electrodes 20 and 28 is segmented by protrusions 34a and 34b of a charge stopping layer, and weight coefficients are given respectively. As a result, required circuits can be integrated together with the CTD on one substrate, and constitution is simple.

Filed: 1994-02-16
Abstract: PURPOSE:To excite surface acoustic waves in one direction with a single phase structure and to improve energy conversion efficiency by arranging bus bars for which plural electrode fingers for inputting the signals of the same phase are bundled and connected on the right and left of the electrode finger, cancelling one direction and strengthening the other direction. CONSTITUTION:In the three-phase type UDT of a comb-line electrode, the electrode fingers 121... are respectively connected to the bus bars 111 and 115 for connecting grounded electrodes and the bus bars 113 and 114 and 112 and 116 for high frequency signals provided with the phase difference of 60 deg. at a center frequency and arranged on the right and left. The phases of electric fields among the electrode fingers 127, 128... are shifted by 120 deg. each and thus, since the excited surface acoustic waves advancing in a right or left direction are strengthened or cancelled with each other between the electrodes, only the surface acoustic waves advancing in the right direction are excited. Thus, the three-phase UDT is realized with a single layer structure without the need of a gap cross electrode, loss is made small and highly efficient communication is performed.

Title: Dichromatic electrophotographic copying method
Inventor: INOUE SATORU
IPC: G03G15/01
Filed: 1979-02-22
Abstract: PURPOSE: To obtain a clear dichromatic image by using colored and black toners charged with electricity of reverse polarities in a dichromatic electrophotographic method and charging the colored toner, mixed into a black developer, with electricity of the same polarity as the polarity of the black toner by friction with a carrier in the developer.  
     CONSTITUTION: Red toner RT is prepared, e.g. from a styrene-acrylic copolymer and Pigment Red 57, and it is mixed with iron dust carrier RC to form a red developer. On the other hand, carbon black is mixed into the copolymer to prepare black toner BT, and iron dust carrier BC coated with polyvinyl butyral is mixed into the toner to obtain a black developer. Thus, toner RT is charged negatively, and toner BT positively. By mixing toner RT and toner BT into carrier BC toner RT is, however, charged positively, and the charge quantity is smaller than that of toner BT as shown by the figure. Accordingly, red development is carried out at first. Even if a little toner RT is mixed into toner BT, toner RT first shifts into the black image of a photoreceptor, so the performance of the black developer is not deteriorated, and the image undergoes no change in black tone.
