Patent JP-H0487530-A (JP)
Title: Alternator voltage regulator
Inventor: MATSUI BUNJI
IPC: H02J7/16
Filed: 1990-07-24
Abstract: PURPOSE:To operate an alternator with maximum output power at all times by a constitution wherein a DC-DC converter controls the output voltage of the alternator not to drop below approximately half of the noload voltage corresponding to the rotation of the alternator. CONSTITUTION:A rotation-voltage converting circuit (RV) 13 is set with a voltage about half of the noload voltage corresponding to the rotation of an alternator 6. Output voltage V1617 of a DC-DC converter is controlled to be V1 so long as no command is provided from a voltage comparing circuit 12. The voltage comparing circuit 12 compares the output voltage of the RV 13 with the output voltage V4,5 of the alternator 6 and provides a command to the DC-DC converter 11 if the former is higher. The DC-DC converter 11 then lowers the output voltage V16,17 so that the output voltage V4,5 of the alternator 6 drops below the output voltage of the RV 13. Consequently, output can be taken out stably up to the maximum power point of the alternator 6.

Abstract: PURPOSE:To enable the automatic and accurate winding of a cable onto the next layer at the edge of a collar by applying the constitution wherein the fluctuation of a winding cable in the previous turn is detected for every turn, and causing the predetermined twisting movement of the cable or a bobbin when the fluctuation exceeds the predetermined value. CONSTITUTION:An image processing mechanism 1 is used to continuously monitor the winding state of a cable 6 and a collar edge distance D is always measured for each turn of the cable 6. Also, the cable 6 is twisted right with a correction mechanism at the point B1 where a maximum fluctuation distance D1 is given among the measured collar edge distance values, and while a gap of distance l is being maintained from the maximum fluctuation point A1 of the previous turn, the cable 6 is wound. In this case, the length l of the gap satisfies the condition of l<=D/2. Then, the cable 6 is twisted left with the correction mechanism at the point B2 of a minimum fluctuation distance D2, and not at the point B1 of the maximum fluctuation distance D1 among the measured collar edge distance values, and a gap from the minimum fluctuation point A2 of the previous turn is kept 6 is kept close for winding the cable 6.

Title: Electrostatic chuck
Inventor: MIZUMURA JUNJI
IPC: B23Q3/08
Filed: 1988-08-06
Abstract: PURPOSE:To surely perform release of a wafer by providing a driving mean for electrically insulating a piezoelectric element from electrodes for generating electrostatic force on a dielectric and wafer. CONSTITUTION:As a wafer 3 is brought in contact with the dielectric 2 of an electrostatic chuck and voltage is applied between electrodes 1a, 1b by a power supply 6, the wafer 3 is attracted with the electrostatic force. Thus, after the desired processing is applied, the applied voltage is released by the power supply 6. In this state, the wafer is kept to be attracted under polarization generated on the dielectric 2. Next, as voltage is applied on the piezoelectric element 4a by a power supply 7, it is extended so as to receive the release force exceeding the attractive force due to the polarization generated on the dielectric 2, thus surely releasing the wafer from the dielectric 2. As the voltage applied on the piezoelectric element 4a is released, the piezoelectric element 4a is returned in the original length. In this case, the piezoelectric element 4a is electrically insulated from the wafer 3 and electrodes 1a, 2b so that there occurs no trouble even if the voltage is applied on the piezoelectric element 4.

Title: Board positioning mechanism for ic inserting device
Inventor: KURIHARA MITSUGI
IPC: G01R31/30
Filed: 1985-09-06
Abstract: PURPOSE:To hold a socket position constant even if a board has inferior size precision by providing the 1st pressing means which is provided on the opposite side of a stopper and allows the board to abut on the stopper and the 2nd pressing means which fits the board in the cut of the stopper. CONSTITUTION:An IC gripping device 84 is provided with a couple of claws 86 and 88, and a rod 90 penetrates the claws 86 and 88; and an air cylinder 92 is coupled with one end of the rod 90 and the cylinder 92 is fitted to a bracket 94. The stopper 96 projects downward at the intermediate part of the bracket 94 and serves to stop the board at a constant position when the claw 88 operates. Therefore, when the cylinder 92 operates, the claws 86 and 88 come closer to each other along the rod 90, but the claw 88 stops at an invariably constant position, which varies with the size of an IC 10. Consequently, even when the IC 10 varies in size and the board 14 shifts in socket position, a program is set on the basis of the stop position of the claw 88 and consequently a device 84 is moved onto the socket 16 of the board 14 accurately.

Abstract: PROBLEM TO BE SOLVED: To produce an electric oven provided with a window glass having an improved visibility by using a glass which is coated with both an electrocoraductive membrane transparent at least in a visible light range and a stainproofing membrane. SOLUTION: This microwave oven is provided with a window glass whose glass base board 1 is coated with both an electroconductive membrane 3 transparent at least in a visible light range and a stainproofing membrane 5. The formation of an alkali barrier membrane 2 consisting of silica or alumina silica between the glass base board 1 and the electroconductive membrane 3 is preferable since this enables the improvement of the adhesion of the electroconductive membrane 3 with the glass base board 1.  The production of the window glass is performed as follows: an electroconductive membrane transparent in a visible light range is formed on at least one side of a glass base board 1 for the window glass, which has been washed cleanly, subsequently the whole body is cooled by wind to strength the formed membrane, and a stainproofing membrane containing a fluoride carbon group is formed on the electroconductive membrane.

Abstract: PURPOSE:To prevent a settlement of a floor plate or a pipe deformation and facilitate handling of the mat when a flow communication is performed by a method wherein a foam resin sheet having a resin pipe for a thermal medium flow passage buried therein is provided with several hard fine elongated plates, their longitudinal directions are crossed at a right angle perpendicular to a bending direction of the sheet and they are adhered to each other with a certain spacing being left therebetween. CONSTITUTION:A floor heating mat 1 has a foam polyethylene sheet 2 and a resin pipe 3 buried in the sheet 2. The resin pipe through which thermal medium such as hot water is passes is disposed to cover an entire sheet. Hard several fine and elongated plates 4 harder than the foam resin sheet 2 are adhered to a rear side of the foam resin sheet 2. Adhering of the fine and elongated plates 4 is carried out in such a way as their longitudinal directions are crossed at a right angle perpendicular to a bending direction of the foam resin sheet and they are spaced apart from each other, resulting in that the mat 1 can be bent and rounded. With such an arrangement, the floor settlement or a pipe deformation is hardly generated and its handling (transportation or storing or the like) may easily be carried out.
