IPC: G03F7/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To increase the controllable range of a dampening water and to make the dampening water free from isopropanol(IPA) by carrying out processes of applying a hydrophilic swellable layer on a substrate to form an ink-repelling layer, impregnating the layer with a photosensitive compsn., and laminating a protective layer thereon. SOLUTION: This method for producing a photosensitive planographic printing master plate having a hydrophilic swellable layer on a substrate includes the following processes. (1) A hydrophilic swellable layer is formed on a substrate. (2) A photosensitive compsn. is applied on the hydrophilic swellable layer to infiltrate. (3) A protective layer is formed to cover the surface of the hydrophilic swellable layer impregnated with the photosensitive compsn. In this method, it is preferable to continuously perform the applying and drying processes. Namely, a substrate is nipped by nip rollers and released from a web roller at a const. rate. Then a coating device selected from a coating means is used to apply a primer layer compsn., and then the substrate is carried in a drying and hardening device to form a primer layer.

Filed: 1982-02-16
Abstract: PURPOSE:To prevent the short-circuit between wirings of remnant pattern layers due to an RIE, by previously doping an impurity into the etching region when a conductor layer or a semiconductor provided on the surface having unevenness is etched. CONSTITUTION:When the second layer wirings 23-25 are formed on the surfaces of the first layer wirings 21 and 22 via insulation films 32 and 33, first an undoped polycrystalline Si layer 34 is formed on the surfaces of insulation films 32 and 33 which are projected. Next, an impurity is doped by using masks 35-37 resulting in the formation of impurity doped regions 38-40. These regions has high etching speed due to an RIE and are etched faster than the undoped polycrystalline Si. Therefore, polycrystalline Si does not remain on the side wall of the projected insulation film 32 after etching. Thereafter, the masks 35-37 are removed, and ions are implanted into the remnant wiring pattern resulting in the formation of the second layer wirings 23-25. Thereby, the short- circuit between multilayer wirings due to the remnant pattern layer can be prevented.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To provide an echo canceller where tandem connection is surely avoided and to provide an echo control method that avoids deterioration in voice quantity when echo cancellers are in tandem connection. SOLUTION: Prior to communication start, terminals 91, 92 of a switch 9 and terminals 101 and 102 of a switch 10 are connected. Furthermore, the echo canceller 7 stops echo cancellation and 2-wire transmission lines 1, 2 get through.

Thus, the echo canceller 7 starts echo cancellation. Simultaneously, the controller 11 connects the terminals 91, 92 of the switch 9. Thus, a disable ring tone generator 8 sends a disable ring tone to stop the operation of the echo canceller to the echo canceller at a remote talker.

Title: Number of cylinders varying type engine
Inventor: IGARASHI TERUO
IPC: F02D13/06
Filed: 1984-02-14
Abstract: PURPOSE:To recover exhaust energy, by a method wherein, when the quiescent cylinder of a number of cylinders controlling engine is in a suction stroke or in an explosion stroke, an operating cylinder in an exhaust stroke is communicated with the quiescent cylinder through a coupling pipe to feed exhaust gas in the operating cylinder into the quiescent cylinder. CONSTITUTION:A cylinder 21, which is normally operated, is coupled with a quiescent cylinder 22, which stops operation during operation at a low load, through a coupling 23, and coupling valves 24 and 25 are mounted to each cylinder. During operation with the reduced number of cylinders, with an electromagnetic valve 34 opened, compressed air is fed to a cylinder 32 to depress down a shaft 27, and cams 35, 36, and 37 are brought into contact with coupling valves 24 and 25 and a decompression valve 17 to operate each valve in linkage with a crank shaft 38. When the cylinder 21 is in an exhaust stroke, the cam 35 opens the valve 24, and when the cylinder 22 is in an explosion stroke, the cam 36 opens the valve 25. This causes exhaust gas, fed to the cylinder 22 from the cylinder 21 through the coupling pipe 23, to be exerted on a piston 9 in an explosion stroke so as to push it up.
