Title: Controller for automatic clutch
Inventor: SHIMAZU TOSHIAKI
IPC: B60W10/10
Filed: 1980-01-31
Abstract: PURPOSE: To smoothly operate a friction clutch depending on the running condition of a vehicle, by using the negative pressure of an intake pipe and the speed of the vehicle to control air flowing out of the atmosphere chamber of an actuator for operating the friction clutch, to regulate the engagement speed of the clutch.  
     CONSTITUTION: In starting, a control valve 30 is closed because of the strong negative pressure of an intake pipe 4 and another control valve 50 is also closed because of the low speed of a vehicle. As a result, the piston 82 of an actuator 8 is controlled by only a valve 86 and an orifice 21 to slowly engage a clutch 2. In step-up shifting during a drive at a speed not lower than a prescribed level, the valve 50 is open and the other valve 30 is also open because of the weak negative pressure of the intake pipe. As a result, air in an atmosphere chamber 85 is conducted through a passage 22 and discharged also from ports 31, 51 to quickly engage the clutch 2. In step- down shifting during a high-speed drive, the valve 50 is open and the other valve 30 is closed because of the strong negative pressure of the intake pipe 4. As a result, air in the atmosphere chamber 85 is discharged from the valve 86, the orifice 21 and the port 51 to engage the clutch more slowly than in the step-up shifting.

IPC: H05K9/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To prevent emission of unnecessary electromagnetic wave in an outer interface, and prevent surge noise of a large level from intruding into a device. SOLUTION: Although a current path R1 connected between a ground line 13a of a circuit part inside a device and a ground line 13b of an interface part propagates a ground signal, a high frequency noise element in a ground signal which becomes unnecessary electromagnetic wave is reduced and removed by ferrite beads 151 . Meanwhile, when surge noise of a large level is propagated from the ground line 13b, a semiconductor surge absorber 152 provided to a current path R2 parallel to the current path R1 breaks down and makes a current flow. Thereby, surge noise damps. High frequency noise element which propagates the current path R2 is damped and removed by ferrite beads 153 , 154 provided to the current path R2.

Title: Evaporated fuel treatment device for internal combustion engine
Inventor: HIYOUDOU YOSHIHIKO
IPC: F02M25/08
Filed: 1994-02-02
Abstract: PURPOSE:To inhibit a large quantity of evaporated fuel from being fed to an engine from an evaporated fuel adsorption layer immediately after oiling. CONSTITUTION:A main activated carbon layer 12 and an auxiliary activated carbon layer 14 are series-connected to each other. At the oiling time, evarporated fuel in a fuel tank 21 is led to the main activated carbon layer 12 through an oiling time evaporated fuel passage 20 and adsorbed. At the engine operating time, air flowing to the main activated carbon layer 12 is let flow to the auxiliary activated carbon layer 14 so as to desorb evaporated fuel adsorbed to the activated carbon layers 12, 14 and to feed it into an intake duct 4, while the evaporated fuel in the fuel tank 21 is fed into the intake duct 4 through an operating time evaporated fuel passage 23, that is, making a detour around the activated carbon layers 12, 14. Accordingly, evaporated fuel is hardly adsorbed to the auxiliary activated carbon layer 14 immediately before oiling. As a result, even if the engine 1 is started immediately after oiling and a large quantity of evaporated fuel is desorbed from the main activated carbon layer 12, this evaporated fuel can be adsorbed desirably to the auxiliary activated carbon layer 14.

Title: Eddy-current-type brake
Inventor: ENDO YUJI
IPC: H02K49/02
Filed: 1994-02-03
Abstract: PURPOSE:To increase a braking force without increasing an outward form by a constitution wherein a soft magnetic material is filled into every gap between a plurality of frames. CONSTITUTION:One-pair of grooves 8 whose cross section is semi-circular are formed on adjacent opposite faces of frames 5 for a brake so as to be parallel in the front and rear direction. A filling material in which solid grease has been mixed with an iron powder is injected into the grooves 8. A foamed material by a rubber material is inserted in advance into the outer circumference. Then, a magnetic flux which is generated by applying a current to exciting coils 1 is passed through a magnetic path which is formed between the adjacent frames 5 and individual magnetic-pole iron cores 2 and a rail at the lower part of brake shoes 3 at lower ends of the magnetic-pole iron cores 2. However, the magnetic flux which is passed through the magnetic path can be increased sharply because the filling material is interposed in gaps formed between the adjacent frames 5 so as to increase permeability as compared with the air. As a result, a braking force can be increased without increasing an outward form.
