Patent JP-2001015359-A (JP)
Title: Variable inductor
Inventor: OKUYAMA YUJI
IPC: H01B7/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To enable an incoming and an outgoing conductive wire to offset their inductances by each other by a method wherein the incoming and outgoing conductive wire are provided in a sheath, and an electric wire where the center of gravity of the outgoing conductive wire in a cross sectional shape is set identical to that of the incoming conductive wire in a cross sectional shape is used. SOLUTION: The sectional centers of gravity of an outgoing conductive wire 1 which is freely replaceable by an incoming wire and an incoming copper wire 2 are both located at the center of an electric wire. A magnetic field produced by a current that flows through the outgoing conductive wire and another magnetic field produced by a current that flows through the incoming conductive wire are almost completely offset by each other at a point distant enough from the electric wire. When the background of a coil is enhanced in electron density, even a coil different from a usual non-inductive wound coil is very slightly reduced in inductance. A non-inductive wound coil is originally low in inductance, so that this property is apt to occur in it.  Therefore, a coil becomes lower in inductance with an increase of a non-inductive part in exclusive factor, and a region of negative inductance can be easily realized.

Title: Method and device for laser welding
Inventor: SUGIYAMA SADAO
IPC: B23K26/046
Filed: 1983-10-07
Abstract: PURPOSE:To condense exactly a laser for working to a weld point and to perform welding with high accuracy by detecting the change in a weld line and the inside diameter of a pipe by a laser for detection and controlling a laser for working according to the detected information. CONSTITUTION:A laser 2 for detection from a laser oscillator 1 for detection is first condensed through a reflecting mirror 4 and a condensing system 11 to the inside circumferential surface of a pipe 7. Then the laser 2 is reflected there are returns to the direction where the laser is irradiated. A part of the laser is reflected by a dichroic mirror 3 and enters a detector 16. If the spot position of the laser 2 strikes the inside circumferential surface of the pipe, the laser is detected in a detector 16 by the reflection thereof but if said position strikes a notch part 20a, the laser is not detected. A mechanism 15 for moving the condensing system is actuated via a control device 19 by the signal from the detector 16. More specifically, the device 19 is inputted with the laser 2 and feeds a signal to the mechanism 15 after making prescribed calculation to move laterally a support 12 for the condensing system thereby controlling the position of the weld line so as to come to the condensing point of the laser 2. Said device stores the pipe and a condensing lens 5 and thereafter irradiates a laser 8 for working. Welding is thus accomplished.

Title: Insulated gate type semiconductor device
Inventor: ITOU HIDESHI
IPC: H01L29/78
Filed: 1981-11-24
Abstract: PURPOSE:To obtain the MOSFET characterized by a small capacity and high  frequency characteristics, by arranging a diffused junction which forms a source and electrodes in a stripe shape without independently providing one unit. CONSTITUTION:A P region 3 is formed in a stripe shape without independently providing one unit. Therefore at least a drain junction, which is formed in the direction perpendicular to the direction of the stripe in the vicinity of the P region that has been formed for every one unit, can be omitted. The area of the entire drain junction is reduced by about 1/2 the conventional area. Therefore an output capacity Coss can be reduced. Since Al layer 9 and 10 having samll resistivity are formed on a polycrystal Si gate 6, the increase in the gate resistance due to the formation of the stripe does not occur. The gate resistance is rather reduced, and the frequency can be improved by e.g. one order of magnitude (f=1/2piRgCis).

Title: Locking device
Inventor: NAGATA KOJIRO
IPC: F16H25/20
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of abnormal sound at the time of half lock and to simplify structure by joining a lock nut to a fixing nut, locking a lead screw by its friction force and locking a locknut system. SOLUTION: Concerning this device, at the time of pulling a manipulating knob connecting a manipulating wire 8 against the elasticity of a spring 5, the joining part 31 of the locknut 3 is rotated in the direction of being separated from the part to be joined 41 of the fixing nut 4 through a stepped pin 32. Thus, the friction force of the lockout 3 to the nut 4 is eliminated to prevent the screw 1 from moving in an axial direction. This movement of the screw 1 is performed by operation force by a fixing member including the fixing bracket 6 of the screw 1 and the fixing part 20 of a pipe 2. At the time of releasing manipulating force to the manipulating knob after the lead screw is moved by a prescribed quantity, the locknut 3 is rotated by the elastic force of the spring 5 to be joined to the fixing nut to regulate the movement of the screw 1 to make a locking state.

Title: Voice detection device
Inventor: HAGIWARA TOSHIO
IPC: G10L21/0208
Filed: 1994-07-18
Abstract: PURPOSE:To reduce the chances of making voice false detection by eliminating ambient noise components using a pseudo-noise generator and a synthesizer and actively detecting main voice signals by a voice analyzer. CONSTITUTION:Ambient noise signals r(i) and output signals u(i) are inputted into a pseudo-noise generator 3 which outputs pseudo-noise signals n'(i). The pseudo-noise signals n'(i) and main voice signals s(i)+n(i) are synthesized in a synthesizer 4 and voice signals u(i)=s(i)+n(i)-n'(i), which are generated by subtracting the signals n'(i) from the main voice signals s(i)+n(i), are outputted to a voice signal output terminal 6. The signals n'(i) are the signals in which ¦n(i)-n'(i)¦ or (n(i)-n'(i))<2> becomes a minimum. Therefore, the signals u(i) become similar to the voice signals s(i) which are to be detected. Moreover, the signals u(i)=s(i)+n(i)-n'(i) are inputted to a voice analyzer 5, the presence or the absence of voice is discriminated and outputted.

Title: Air conditioner for vehicle
Inventor: MURASHIMA KAZUAKI
IPC: B60H1/00
Filed: 1983-10-06
Abstract: PURPOSE:To prevent the excess increase in the quantity of work of a blower motor and lengthen its life, in an air conditioner for a vehicle, in which ram pressure is taken into consideration, by using a window opening or closing signal and a blower motor electricity supply control signal to control the quantity of supplied air. CONSTITUTION:When a window remains closed throughout the drive of a blower 21, a window opening/closing sensor 8 supplies electricity to a relay 6 to turn on its contact 61 to apply electric power to a blower motor 2. When the window is window is opened, the window opening/closing sensor 8 stops suplying electricity to the relay 6, to turn off its contact 61. As a result, a resistor 7 is inserted into a circuit to a blower motor power supply circuit 1 to reduce the power to the motor 2 to restrict the power below the limit capacity of an alternator. The excess increase in the quantity of work of the blower motor 2 is thus prevented to lengthen its life.

Inventor: OSAKI YUMIKO
IPC: G03F1/68
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To correctly reproduce all fine lines including complex patterns with fine lines in different directions, by providing an even and larger number of boundaries than that of the fine lines by which difference in phase between adjacent areas are specified by centering their intersection, and by performing exposure with a phase shifting mask. SOLUTION: When a normal exposure pattern in which four fine lines cross one another is formed, fine lines are formed by using edge of strength 0 which is generated by phase difference of phase 0.π and arrangement is made in such a way that adjacent phases are different from each other. Difference between periodic patterns 1 and 2 is the size of the periodic patterns. The periodic pattern 1 is arranged in such a way that the edge of strength 0 generated by the phase difference corresponds to the whole normal exposure pattern, and the periodic pattern 2 is arranged in such a way that the edge corresponds to fine lines of the normal exposure pattern. Namely, adjacent patterns have phase difference of 180 deg. and fine lines are formed by using edges of strength 0 generated on the boundary between them.

Title: Image forming device
Inventor: KUSUMOTO KEIJI
IPC: G03G15/08
Filed: 1986-08-11
Abstract: PURPOSE:To start image forming operation removing toner lack by executing non-steady replenishing in prior and then executing image forming operation when the image forming operation is commanded by an external input during the non-steady replenishing operation. CONSTITUTION:When non-steady toner replenishing independently of toner replenishing to be executed during image forming operation is commanded through an input device, toner replenishing is continued until toner density detected by a toner density sensor 11 reaches a set value. Consequently, the toner density can be maintained at a proper value. When an external input commanding image forming operation is applied to a switch 92 during the non-steady replenishing operation, the image forming operation is executed by a CPU20 after the end of the non-steady toner replenishing operation. Consequently, the image forming operation can be started under the status removing toner lack, so that excellent reproduced image can be obtained.
