Title: On-vehicle navigation system
Inventor: SEKINE TAKEHIRO
IPC: G09B29/00
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To normally permit the search of a closer route to a route selection made by a driver by a re-searching a route to the destination with road classification in the travel of its own vehicle as a priority route when the road classification in travel and road classification on a guide path are different due to an own vehicle position being off a road on the guide path. SOLUTION: When its own vehicle position coordinates specified by a coordinate computing part 14 based on information from a GPS receiver 5 and a self-contained navigation sensor 6 are not on a guide route, a branch point where its own vehicle ran off the guide route and road classification where the own vehicle was traveling until reaching the branch point are confirmed to set the road classification. Road classification in the present travel of its own vehicle is then confirmed to set the road classification. In the case of judging the difference of road classifications as a result of comparing both road classifications, the road classification in the present travel of the own vehicle is set as a priority road for a route search, and a route to the destination from the traveling position of its own vehicle set as a new starting point is re-searched by a route searching part 20. The re-searching route is transmitted as a guide route to a route guide part 22.

IPC: H04N9/73
Filed: 1994-09-29
Abstract: PURPOSE: To shift to a normal white balance state in a short time after the change of a light source by providing a white balance correcting device to increase the speed of changing the gain of a color signal faster than before the change of the light source when the change of the light source is detected. CONSTITUTION: An integrator 11 digital by integrates a color difference signal B-Y extending over one field period, and this integrated value is made a color evaluation value Vb. Similarly, the integrators 12, 13 input the integrated values of the color difference signal R-Y and a luminance signal Y to a microcomputer 14 as the color evaluation value Vr and a luminance evaluation value Vy. The microcomputer 14 monitors the variation of the luminance evaluation value Vy and he color evaluation values Vr, Vb, and when each variation exceeds each threshold, it judges that the light source was changed.  Then, while the light source is not changed, and its color temperature is kept stable, the changing speed of the amplification factor of the color signal in white balance correction is made slow, and the moderate white balance correction is maintained, and when the light source is changed once, and the color temperature is changed, the changing speed is speeded up, and following this, the white balance correction to meet quicky the color temperature of the new light source is executed.

Title: Leak detecting device for pipe fitting
Inventor: ATSUMI TAKUYA
IPC: G01N1/00
Filed: 1993-09-21
Abstract: PURPOSE:To protect a detector from a condensing gas such as oil vapor or steam, and keep the leak detection highly sensitive by successively arranging a constant temperature bath, an air filter mechanism, and a paper filter mechanism in a transporting pipe toward the detector. CONSTITUTION:A mixed gas of helium and nitrogen is supplied into a pipe 1 from the feed hole 3a of a block 3 arranged on a pipe 1 both ends. An oil vessel 4 alternately feeds high temperature and low temperature hot medium oils around a tube fitting 2 to impart the heat cycle of the pipe 1. A vessel 5 collects the leak gas from the fitting 2 and transfers it to a detector 8 by a pure nitrogen blown through a piping 7 by a transfer pipe 6. A constant temperature bath 9 lowers the temperature of the gas in the transfer pipe 6 to condense it, and the oil and water contents in the gas are removed through a valve 6a. The remaining oil and water contents are again collected by an air filter mechanism 10, and the oil vapor and steam passing it are removed by a paper filter mechanism 11. The detector 8 judges the presence or absence of the leak gas.

IPC: G11B21/12
Filed: 1986-10-03
Abstract: PURPOSE:To prevent each parts from being rubbed against each other, and to prevent the generation of contamination by turning a link by the rotational operation of an eccentric cam, and also, bringing an arum to an up-and-down motion, so as to execute the loading or unloading of a magnetic head. CONSTITUTION:At the time of a loading state, a distance (l) between a cam center 19a, and the abutting point of a cam 19 and a roller bearing 18 becomes maximum. By the rotation of the eccentric cam 19 which follows up the rotational operation of a stepping motor, the distance (l) becomes gradually smaller, by which a roller bearing 18 is drown to the lower side by spring force. In such a state, a link 17 turns centering around a supporting point 16, therefore, an arm 15 fixed to the tip ascends and executes the unloading of a magnetic head 12. At the time of shifting an unloading state to a loading state, it can be executed by reversing the preceding operation. In such a manner, since a flexture part and the arm are not rubbed against each other, the contamination is not generated at all.

Title: Manufacture of semiconductor device
Inventor: HIDA YUKIO
IPC: C23F4/00
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To prevent a re-adhering substance layer from being formed on a pattern sidewall surface and a lien width from increasing upon processing a conductive film with ion milling. SOLUTION: A regist pattern formed through normal photolithography is heated and deformed into a deformed regist pattern 3d, where a height H of the regist is 1/2 a line width L. Since the sidewalls of the deformed regist pattern 3d do not have vertical surface, even if ion milling for a conductive film 2 is performed using the deformed regist pattern as a mask, sputter emitted particles from the conductive film 2 will not re-adhere thereto. Since a mask film is gradually reduced from an edge of the mask by being irradiated with an ion beam IB at a predetermined incidence angle α, an increase in a line width of a wiring pattern is restrained, so that a satisfactory space S is ensured in a self-adjustment manner. Thus, the need for extending an interval between the regist patterns, anticipating an increase in the line width as in the prior art is eliminated.
