Filed: 1994-06-07
Abstract: PURPOSE:To enhance adhesion by composing first and second conductive layers, respectively, of epoxy resin based conductive paste and phenol resin based paste and chemically bonding an epoxy group and a hydroxy group. CONSTITUTION:A solvent of epoxy resin based conductive paste is evaporated and then a phenol resin based conductive paste is applied and eventually they are cured simultaneously. Consequently, a conductive filler of both conductive pastes is mixed with a polymer resin binder in the vicinity of interface thus producing a structure where the interface of electrode varies continuously. This structure provides a low resistance on the interface of electrode and excellent adhesion. the equivalent of epoxy resin in a first conductive layer 107 is set higher by 10-40% than that of hydroxy group in a curing agent, for example. When the first and second conductive layers 107, 108 are hardened simultaneously, chemical bonding can be promoted positively between epoxy group in the first conductive layer 107 and hydroxy group in the second conductive layer 108.

Title: Receiving tube
Inventor: KIHARA ATSUSHI
IPC: H01J29/18
Filed: 1977-10-18
Abstract: PURPOSE: To increase the brightness of receiving tube, and the contrast, and to unify them and further, to increase the freedom of design, by coating the semi- transparent film on the face panel front so that the transmission rate at the center is lower and that at the circumference is greater.  
     CONSTITUTION: The semi-transparent film 15 is coated on the surface of the panel 1 so that the photo transmission rate is lower at the center of the face panel 1 and greater for the circumference. Accordingly, the reflected light from the boundary is weakest at the center, increasing the contrast. On the other hand, since the reflection rate is greater at the circumference of the panel 1, the contrast can be less without lowering the brightness. Accordingly, by adjusting the distribution of the transmission rate of the film 15, the uniform contrast for all the panel 1 can be obtained. Further, since no restriction in designing the width and guard band of the fluorescent body is present, the freedom of design can be increased

Title: Anti-skid control device
Inventor: MATSUDA TOSHIRO
IPC: B60T8/58
Filed: 1989-05-19
Abstract: PURPOSE:To avoid the influence of wheel spin by selecting the smaller wheel speed than the wheel speed selected value in the anti-skid control state at the time of the lateral acceleration of a vehicle being over the specified value and calculating the false speed on the basis of the selected wheel speed. CONSTITUTION:When lateral acceleration over the specified set value is detected by a lateral acceleration detecting means, in the case of selecting the wheel speed lower than the wheel speed selected value in the anti-skid control state, that is, selecting the maximum value among the speed of four wheels at the time of running excluding the anti-skid control time, the high wheel speed from the second on is selected. The false speed imitating the actual speed is then obtained by a computing means on the basis of the wheel speed of the wheel without wheel spin, and using this false speed, the lock state of each wheel is judged, thus controlling the damping pressure to each brake cylinder by a damping pressure control means. Wrong action caused by the wheel spin of the inner wheel at the time of turning is thus prevented so as to enable accurate anti-skid control.

Abstract: PURPOSE:To improve exhaust efficiency by installing stationary and moving blades with a given swing angle in relation to a radial line extending from the center shaft of a rotor so as to make the outside diameter of the rotor to increase toward the exhaust side. CONSTITUTION:Each tip of moving blades 3 has a given swing angle of beta, calculated from the speed of exhausted particles, rotational speed, the effective diameter of a moving blade, etc., against a radial line l from the center shaft of a rotor 2.
