Title: Positive temperature coefficient thermistor
Inventor: NAMIKAWA YASUNORI
IPC: H01C1/14
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To improve a flashover voltage characteristic of a positive temperature coefficient thermistor. SOLUTION: A heat generating peak position which appears on a side face 25 of an element main body 22 of a positive temperature coefficient thermistor 21 is shifted in the thickness direction of the main body 22 from the central part of the side face 25, by forming a gap 28 to one of electrodes 26 and 27 formed on the main surfaces 23 and 24 of the main body 22, so that the current density on the side face 25 becomes relatively lower on the electrode 26 side and the heat generating peak is shifted to the other electrode 27 side or making the first and second half regions of the main body 22 in the thickness direction to have different specific resistances, so that the heat generating peak appears in the higher-resistance region.  Therefore, the flashover voltage characteristic of the thermistor 21 is improved, because the concentration of heat generation at the central part of the main body 22 in the thickness direction is thereby eliminated.

IPC: H04N5/374
Filed: 1987-11-20
Abstract: PURPOSE:To prevent a phenomenon that high luminance subject upper and lower sides to appear in an output signal reproducing image are brightened by impressing a selecting pulse to the control electrode of a transistor used as a photoelectric converting element, and making the potential of the control electrode into a value corresponding to an incident light quantity to a terminal. CONSTITUTION:Before the selecting pulse is impressed to the control electrode of the transistor used as the photoelectric converting element, a capacity connected to a second electrode is charged at a constant level in which a vertical false signal is not generated. Concretely, a voltage VPR is impressed form a power source 24 through switching elements 23-1-23-4 to respective vertical signal lines 11-1-11-4, respectively, and before gate pulses phiG1-phiG4 at lead levels are impressed to the gate of respective picture elements, the vertical signal lines 11-1-11-4 are connected to the power source 24. In such a way, a vertical signal line parasitic capacity is made into a first condition, and it is charged with the voltage VPR, and the signal lines 11-1-11-4 are made into the floating of a second condition. When the gate pulses phiG1-phiG4 at reset levels are impressed, the signal lines are made into the grounding of a third condition.

Abstract: PURPOSE:To enable rear wheel steering to follow the fast behavior change of a vehicle at the time of high speed travel in a four-wheel steering vehicle provided with rear wheel steering mechanism for steering rear wheels by the rotation of a motor. CONSTITUTION:A microcomputer 35 determines a target steering angle according to the vehicle speed, a yaw rate and a front wheel steering angle and also determines a duty ratio corresponding to the difference between the determined target steering angle and the actual steering angle of lateral rear wheels RW1, RW2 so as to supply a driving circuit 36 with a signal indicating this duty ratio. The driving circuit 36 supplies a motor 21 with a driving current proportional to this duty ratio so that the rotation of the motor 21 is controlled to steer the lateral rear wheels RW1, RW2. When the vehicle speed detected by a vehicle speed sensor 31 is large, the duty ratio is corrected in such a way as to be large compared to the time of the vehicle speed being small, so that the driving current to the motor 21 is made large to make the steering speed of the lateral rear wheels RW1, RW2 fast.

Title: Electrically insulated cable
Inventor: KONDO MAMORU
IPC: H01B1/24
Filed: 1987-11-20
Abstract: PURPOSE:To improve insulation breakage strength by preparing a semi-conductor layer made of ethylene-alphaolefin copolymer consisting of a specific element and a conductive compound material mainly composed of carbon black. CONSTITUTION:An internal semi-conductor layer 2 and an external semi-conductor layer 4 are made from ethylene-alphaolefin copolymer consisting of amorphous or low crystalline carbon, and hydrogen, and a conductive compound material mainly composed of carbon black. The above-described ethylene-alphaolefin copolymer contains 75weight% or more of ethylene. An insulator 3 consists of polyethylene or bridged polyethylene. In the electric insulation cable having such a structure as described above, adhesion of a junction surface between the internal semi-insulating layer 2, external semi-insulating layer 4 and insulator 3 becomes solidified, thereby preventing insulation at that area from being destroyed. As a result, insulation breakage can be eliminated on the junction surface that generally represents triggering points for breakage, thereby improving insulation breakage strength of an electrically insulated cable.

Title: Manufacture of semiconductor device
Inventor: YONEDA MASAHIRO
IPC: G03F1/22
Filed: 1988-11-22
Abstract: PURPOSE:To obtain a method for manufacturing a semiconductor device for flattening steps located on the surface of a photoresist by changing the transmission rate of X rays according to the thickness of a mask material. CONSTITUTION:A mask 10 consists of a mask substrate 1 and mask materials 2a, 2b, and 2c. When X rays are directed onto the mask 10, they cannot pass through the thick mask material 2a, a small amount of X rays passes through the medium-thick mask material 2b and a large amount of X rays pass through the thin mask 2c. Also, nearly all X rays can pass through an area without any mask materials, thus allowing a photoresist to be strongly sensitized. Thus, by changing the thickness of the mask materials 2a, 2b, and 2c, the amount of X rays projected to a photoresist 5 can be changed and the amount to be eliminated is changed according to the difference of sensitization. As a result a photoresist film pattern 6 with a flat surface can be obtained as a photoresist after development treatment.

IPC: H01R4/24
Filed: 1990-10-31
Abstract: PURPOSE: To completely protect a connection portion from the effects of an environment by causing a piston or a pole, integrally molded with a housing to enter a void so that sealing material is caused to flow into a slit to adapt the same around a conductor, when contact elements are disposed around a conductor. CONSTITUTION: After the insertion of four wires 18a, 18b, 20a, 20b, a cap 14 and a base portion 16 are squeezed together, so that a housing 12 is brought into a closed state. When the cap 14 and the base portion 16 are moved in mutual directions, an H-shaped element 38 captures wires 18b, 20b, one part of an insulating layer is separated so that the wires are connected electrically, and a second H-shaped element likewise puts the wires 18a, 20a in connection. At the some time, respective pistons enter facing voids to thrust down sealing material 48 beneath slits, so as to form sealing portions having high reliability between the wires and the cap 14 or the base portion 16. In this way, since the voids are disposed between the H-shaped elements and the inlets of the respective slits, environment sealing portions are formed so that the infiltration of humidity and other contaminants having adverse effects on the connection of the H-shaped elements through the slits is prevented.

Title: Discotic liquid crystal element and aligning method
Inventor: KANBE JUNICHIRO
IPC: H01M10/0565
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To form a columnar structure of a discotic liquid crystal uniformly in the perpendicular direction to a substrate by forming a discotic liquid crystal layer in such a manner that plural side chains of the discotic liquid crystal molecules in the layer are aligned perpendicular to the substrate on the interface of the substrate. SOLUTION: For example, when a perpendicular aligning agent (ODSE) is applied for the perpendicular aligning treatment, alkyl long chains 31 of ODSE molecules are aligned to stand on the surface of the substrate. Then alkyl long chains 32 of azacrown molecules which strongly interact with ODSE change the direction to be aligned parallel to the alkyl long chains 31 of ODSE, and as a result, strong aligning force is given to the cores 33 of azacrown molecules to be parallel to the interface. The liquid crystal molecules form self-organized columns by the interface of each other. Thereby, a monodomain structure with each column aligned perpendicular to the substrate surface can be obtd.
