Patent JP-H02252312-A (JP)
Title: Jfet analog switch eqipped with gate current control
Inventor: DEREKU EFU BOUAAZU
IPC: H03K17/06
Filed: 1989-07-11
Abstract: PURPOSE: To keep an output voltage to be a true level regardless of fluctuation in a nominal voltage level due to a current subtracted by a control circuit by providing separately a true and a nominal input voltage line and extracting the switch output only from the true input level. CONSTITUTION: A true input voltage line 18 is connected to an input terminal T1 at which an analog input voltage to be switched is received. Furthermore, a nominal input voltage line 20 connects to a terminal T2 which receives a nominal input voltage. The voltage on the input voltage line 20 tracks a true input voltage level on the line 18 but has a difference by several milli-volt from the true level because of a current subtracted by a switching circuit. The voltage on the line 18 is applied to a drain of an MESFETM1 and its source connects to an output terminal T3. An FET with a large area is required for the FETM1 to produce a low switching resistance. However, since the FETM1 cannot be forward-biased, a steady-state gate current should be zero. Provision of a high gate drive current is suppressed to block forward-bias for on/off state in the steady-state.

Title: Display device
Inventor: WAKIMOTO SABURO
IPC: G09F13/04
Filed: 1988-07-20
Abstract: PURPOSE:To accomplish a thin, high brightness display device by specifying the pitch of plural fluorescent lamps, a distance between said lamps and a light scattering member, and a distance between said member and a reflector. CONSTITUTION:The distance (h) between the fluorescent lamps 1 and the light scattering member 4 is specified to h=1.5 to 4phi. If h<1.5phi, the boundary be tween a reflecting plane 4a and a reflecting plane 4b appears as brightness irregularity, whereas if h>4phi, the brightness irregularity is too much improved. Therefore the separating effect of the reflecting planes 4a and 4b weakens. The disposing pitch (l) of the fluorescent lamps 1 is then specified to 1.5-2.5m. If l<1.5m, the number of fluorescent lamps increases unnecessarily, whereas if l>2.5m, the fluorescent lamps irradiate remote areas with light. Therefore, the effect that the reflecting plane 4b intensifies light irradiating the reflecting plane weakens. In such a way, the distance between the light scattering member 4 and the fluorescent lamps 1 is minimized, whereby the display device can be reduced in thickness and offers higher brightness.

Title: Multistage egr valve
Inventor: DOBASHI KEIICHI
IPC: F02M25/07
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To improve opening and closing responsiveness by forming a pressure reducing valve which decompresses pressure in a piston chamber rapidly at the time of exhausting air in the piston chamber into which positive pressure is supplied, in a valve whose lift of a valve for opening and closing an EGR gas passage is controlled in multistage by a plurality of pistons. SOLUTION: This EGR valve can control the EGR amount in three stages, where air is supplied to a first piston chamber 16 from a first port 18 in a stroke S1 to advance only a first piston 10. In a stroke S2, the air is supplied to a second piston chamber 17 from a second port 20, and the second piston 14 is advanced along with a movable cylinder 7. The air is supplied from both the ports 18, 20, and is advanced in the stroke S3 corresponding to the sum of the stroke S1 and the stroke S2. In this case, by forming a pressure reducing valve 21 which decompresses the pressure of the first piston chamber 16 rapidly by any port other than the first port 10 at the time of exhausting the air pressure of the first piston chamber 16 from the first port 10, it is possible to shorten the valve-closing time of the EGR valve.

CONSTITUTION:Initial- and latter-stage saturable reactors 21 and 22 are connected with each other with a common winding 29 for resetting saturable reactor which is wound so that a magnetic flux can be produced in the latter-stage reactor 22 in the direction opposite to the magnetic flux produced in the initial- stage reactor 21 by a main circuit current when the magnetic flux is produced in the reactor 21. Namely, a magnetic flux which is opposite in direction to the magnetic flux of an original resonance circuit RC3 is induced in the latter- stage saturable reactor 22. As a result, the reactor 22 is previously reset when the reactor 21 starts to operate. Therefore, no special saturable reactor resetting power source device is required.
