Title: Exhaust controller for engine
Inventor: YAMADA TETSURO
IPC: F02B27/02
Filed: 1989-03-10
Abstract: PURPOSE:To suppress the generation of torque bottom which is generated at a selection time point by installing an exhaust control valve midway in an exhaust passage and controlling the exhaust control valve once to closure side when a suction passage is selected, in the constitution in which the length of the suction passage can be selected. CONSTITUTION:A surge tank 23 common to each cylinder which is connected through the second suction pipe 22 onto the suction port 14 of each cylinder of an engine 1 is formed into a vertically half divided structure, and four of the first suction pipes 24a are formed integrally in an upper side tank 24. One edge of the first suction pipe 24a is opposed, keeping a prescribed interval, to the second suction pipe, and the effective suction pipe length of a suction device can be selected by opening and closing the gap between the both suction pipes 22 and 24a by sliding a slider 27 arranged in shiftable manners between the opposed parts. Further, an exhaust control valve 30 is installed into the collection part of an exhaust manifold 29 connected with an exhaust port, and is controlled to the closure side in the low speed revolution of the engine and to the opening side in the high speed revolution, and further controlled once to the closure side when the suction pipe length is selected.

Title: Production of magnetic recording medium
Inventor: WAKAMATSU HIROAKI
IPC: C23C14/06
Filed: 1986-03-19
Abstract: PURPOSE:To obtain a magnetic recording medium which is provided with both of good sliding durability by a hard carbon film and good surface lubricity by a lubricative carbon film by uniformly forming line ruggedness on the surface of the hard carbon film. CONSTITUTION:A mask adequate for etching to roughen the surface of the hard carbon film can be formed by etching along the grain boundaries of an aluminum film 14 and therefore, the fine ruggedness can be uniformly formed on the surface of the hard carbon film 13. Advantage can be thereby taken of the sliding durability of the hard carbon film 13 and the lubricity of the lubricative carbon film and the magnetic recording medium having the lower contact resistance to a magnetic head is easily obtd. Since the fine ruggedness corresponding to the ruggedness of the hard carbon film 13 is formed on the surface of the lubricative carbon film 15, the contact area with the magnetic head is decreased and the contact area with the magnetic head is decreased and the contact resistance to the magnetic head is decreased.

Title: Color filter and production thereof
Inventor: KUSUKAWA HIROYUKI
IPC: G02B5/20
Filed: 1989-03-14
Abstract: PURPOSE:To obtain the color filter which is relatively inexpensive and has high reliability and the low reflectivity in a black matrix part by forming the black matrix of a polyimide resin dispersed with light shielding material. CONSTITUTION:The light shielding materials are previously dispersed into polyamic acid which can be easily patterned by an alkali and the film thereof is formed. After the film is patterned to a desired shape, the polyamic acid is imidized by heating. Since the black matrix is formed of the polyimide resin dispersed with the light shielding materials, the reflectivity in the black matrix part is suppressed to an extremely low level. Since the reliability of the material itself is high, the black matrix superior in heat resistance, light resistance, etc., as compared to the case of forming the black matrix by a dyeing method, etc., is formed.

Title: Magnetic disc device
Inventor: TOKIDA KATSUHIRO
IPC: G11B5/55
Filed: 1983-04-08
Abstract: PURPOSE:To attain the setting of a comparatively fast object speed while preventing malfunction of movement of a head because of the fluctuation in a power suply voltage by controlling an object speed converting gain to a prescribed value in response to rise or drop of the power supply voltage. CONSTITUTION:When a power supply voltage 4 of a power applied to an actuator moving the head rises, the potential rise at a node 20 whose potential is equal to a potential of a reference power supply 13 when the voltage is normal is suppressed by a diode 16 and a reference current flowing to a gain setting terminal 15 of an object speed converter 2 is constant. On the other hand, when the voltage V falls down, the voltage at the node 20 is also dripped in proportion thereto and the reference curent flowing to the terminal 15 is dropped. Thus, the reduction in the force of the actuator is coped with at deceleration by reducing an object speed signal at the drop in the power supply voltage and the rise in the transient moving speed is prevented at the voltage rises. As a result, an error of head movement due to the fluctuation in the power supply voltage is prevented and the comparatively fast object speed is set.
