Title: Field effect transistor
Inventor: OKA SADAJI
IPC: H01L29/812
Filed: 1993-06-16
Abstract: PURPOSE:To enhance the withstand voltage between a gate and a drain by a simple structure by a method wherein a gate electrode and a drain electrode are arranged in the direction intersecting with the edge where the first crystal face and the second crystal face are adjacently formed. CONSTITUTION:A source electrode 40 and a drain electrode 50 are arranged in the direction vicinity intersecting with the edge 80 to be formed by the first and the second crystal faces 11 and 12 which are brought into contact with each other. The source electrode 40 and the drain electrode 50 are formed with ohmic property against an N-type GaAs layer 20 through the intermediary of a high-doped N<-> type GaAs layer 30. The electric field, between a gate electrode 60 and the N<+> type InGaAs layer 30 on the side of the drain electrode 50, is finely dispersed on the edge 80 in the stage formed in atomic unit, and the withstand voltage between the gate and the drain can be made high.

Title: Pal-secam signal reproducing device
Inventor: KIKUCHI KAZUYUKI
IPC: H04N9/00
Filed: 1990-06-01
Abstract: PURPOSE:To eliminate a time difference between a chrominance signal and a luminance signal by incorporating a delay line into a SECAM signal color demodulation IC so as to make the variation in a delay time of a chrominance signal output relatively equal to that of a luminance signal caused by the variation in the IC. CONSTITUTION:A SECAM chrominance signal is delayed by a time TS at a bell filter 4 and by a time Td at a de-emphasis circuit 6 and delayed by a time TL at filters 7, 13 or 7, 14. In order to match a delay time of a luminance signal with that of a color difference signal, a delay line 24 whose delay time is Tc1=(Ts+Td) is inserted in a path for the luminance signal. A delay time TY of a delay line 42 is selected so as to be equal to the delay time TL of the filters 7,13 or the filters 7,14. Since the delay line 42 and the filters 7,13 and the filters 7,14 are incorporated in one and same IC, the variation in the delay times TL, TY varies in a same tendency with the variation in the signal processing IC1, then the delay times TL, TY are not relatively changed and the time difference between the chrominance signal and the luminance signal is not caused even when the variation in the IC takes place.

Title: Automobile light control device
Inventor: TSUCHIYA RIYOUICHI
IPC: B60Q1/02
Filed: 1981-09-14
Abstract: PURPOSE:To start an engine while a car is at a halt without turning on head lights so as to reduce loads by providing a memory circuit which is turned into a set condition by a car running signal to make the switching element connected in series with a key contact conductive. CONSTITUTION:While a car is at a halt, no signal P from a speed sensor 26 is fed into a memory circuit 23, which is thereby kept in a reset condition, making a switching element 18 non-conductive, therefore, when a key is turned to a starting position, a lighting contact 17c is opened and relays 10, 11 closing a head light circuit are disconnected from a battery 15, thus no head light is turned on to reduce battery loads. Next, when the key is returned to a lighting position after the engine has been started, the lighting contact 17c is closed, then head lights 4 are turned on if a transfer switch is turned to the ''manual'' side but are not turned on while the outside is bright if the transfer switch is turned to the ''automatic'' side. When the engine is to be restarted while the car is running, the head lights 4 are not turned off, thereby no trouble occurs for running at night, and the driver can be protected from forgetting to put out the lights.

Further, a cutout 21 of the same shape as that of the cutout 11 of the support 11 is provided even at the material 20 so that, when the material 20 is mounted at the edge 10a, a peripheral edge of the cutout 11 of the support 15 is superposed on that of the cutout 21 of the material 20.  Thus, the plate material 10 can be effectively and easily mounted on the plate 81.

Title: Production of metal-coated optical fiber
Inventor: SANADA KAZUO
IPC: C03C25/10
Filed: 1991-05-21
Abstract: PURPOSE:To obtain high-strength metal-coated optical fiber excellent in heat and radiation resistance by forming a metal coating layer in a hydrogen atmosphere and then heating the resultant coating layer. CONSTITUTION:A casing 4 of a metal coater 5 is equipped with four spare chambers (4a) and hydrogen gas is fed. The hydrogen partial pressure is decreased stepwise from a part connected to the coater 5 to the spare chamber (4a) in an upper stage to which an optical bare wire 2 is introduced. For example, the hydrogen partial pressure in the spare chamber (4a) in contact with the coater 5 is regulated to 2.0 kg/mm<2> and successively decreased to 1.5 kg/mm<2>, 1.0 kg/mm<2> and 0.5 kg/mm<2> to the upper part. A melt of a metal (e.g. aluminum) forming a metal coating layer is fed to the coater 5. A preform 1 for the optical fiber is initially drawn in a spinning furnace 3 to provide a bare wire 2, which is then passed through a metal coater 6 while being wound at a prescribed linear velocity to form a metal coating layer (0.1-0.3mm thickness) in a hydrogen gas atmosphere. The resultant coating layer is subsequently heated at 150-250 deg.C for 2-5hr to afford the subject optical fiber.

Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent the infiltration of endotoxin from a dialyzate side to a blood side by interposing an endotoxin adsorbent in dialyzate side flow passages. SOLUTION: Fibers 21 which adsorb the endotoxin are interposed between hollow fiber membranes 3 forming the dialyzate side flow passages. These fibers 21 are arranged at the hollow fiber membranes 3 or may be knitted among the hollow fiber membranes 3.

The ratio of the endotoxin adsorbent cross-sectional area to the membrane cross-sectional area is preferably specified to about 5 to about 90% in the case of the fibers 21. About 20 to about 50% is more preferable. Endotoxin adsorption efficiency is higher at about >=20% and the assembly of the blood dialyzer is easier at about <=50%. The endotoxin concn. of the dialyzate may be lowered below the detection threshold and endotoxin prohibition performance improved by this constitution.
