Title: Mold for polyurethane forming
Inventor: HIRATA YUTAKA
IPC: B29K105/04
Filed: 1993-05-19
Abstract: PURPOSE:To quickly and easily set an insert member and prevent formation of a recess on a molded piece by attaching a base end part of a holding member to which the insert member is to be set slidably to either an upper mold or a lower mold movably or rotatably. CONSTITUTION:An insert member 10 is inserted slidably from a head end of a rail 7 by lifting an upper mold 1 and rotating a holding member 5. When the insert member 10 is set so as to be pinched at its both sides by the rail 7, the holding member 5 is rotated and halted at a specific place, a polyurethane foaming raw liquid 9 is injected into a space surrounded by the upper mold 1 and a lower mold 2, and the molds are clamped by a mold clamping means 4. After the polyurethane raw liquid 9 is foamed and cured in the molds 1 and 2, the molds 1 and 2 are opened, so that a molded piece is obtained integrally with the holding member 5. At that time, a base end part 6 of the holding member 5 is rotated so as to easily pull out the molded piece and the molded piece is pulled out.

Filed: 1990-05-30
Abstract: PURPOSE:To reduce a variation in a thrust force by functionally separating a position information permanent magnet and a field permanent magnet, and forming a field distribution by the magnet in a sine waveshape state. CONSTITUTION:Positions of pole detecting Hall elements 31 - 33 are moved outside in a direction perpendicular to the moving direction of a movable element on a movable element board 1, and disposed outside from the opposed parts of field permanent magnets 51 - 58 and 71 - 78. A magnetic field distribution is in a trapezoidal wave state inside the opposed part, but becomes near a sine wave toward the outside. The winding width of armature coils 21 - 23 is T/3 when a magnet pitch is T. If the width is large, a variation in a thrust force upon change of the position of the coil is not abrupt but made uniform.

Abstract: PURPOSE: To rightly measure a floating quantity of a base board without affected by factors except thermal deformation by judging a floating quantity from a reference plane height found from a pushing quantity and pressure of a support pin for supporting the base board and the lead height of a part which is measured and operated. CONSTITUTION: In rising of a rising plate 105, since a pin 111 of a support pin 107 which is inserted into a fixing hole 106 of a base board 103 is pushed in by the base board 103, its pressure is detected by a strain gauge 112.

Secondarily, the laser is cast 101 on a measuring point 104 so as to measure and operate the height of the lead of the part, and the floating quantity of the base board 103 is calculated by subtracting the reference height and the lead height size of the part from this height. Superiority/inferiority of the base board 13 can be judged by comparing this floating quantity and a threshold.

Title: Controller for power converter
Inventor: IKEDA KATSUMI
IPC: H02M7/48
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To improve the output voltage characteristic by inputting a converter current to a transfer function circuit for improving a virtual damping of a filter, and by changing a voltage command value by an output signal of the transfer function circuit, thereby compensating a voltage drop of a serial reactor at a speed higher than the response of a voltage control system. SOLUTION: A load current IL is detected by a detector 6a, and the average value of a load current is detected by an average value detection circuit 805. If the average value of load current is lower than a set point, then the output of a control circuit 806 is zero. If it is higher than the set point, then a result obtained by subtracting the set point from the average value of the load current is output to the control circuit 806, and subtraction from the output of an amplitude command generating circuit 802 is performed by an adder-subtractor 813 via a transfer function 807. Then, its output is multiplied by an output from an AC sine-wave reference oscillating circuit 801 and used as an output voltage command VC*, therefore, if the average value of load current exceeds the set point, then the output voltage command VC* also decreases.  Accordingly, the output voltage VC also decreases, and thus a load current IL also decreases and therefore the output wiring is protected from overcurrent.

Title: Sheet collecting device of printer
Inventor: SUZUKI AKIRA
IPC: B65H31/26
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent jam occurrence and allow reduction of the bottom area of a sheet collection chamber. SOLUTION: A slope 24 inclining upward as going forward in the exhausting direction and a sheet guide 25 are provided in a sheet collecting chamber 17 equipped with a full sense means 20 which senses the full condition with sheets. Even if sheet(s) S is accommodated in the chamber 17 in the condition that its two ends are hopped up owing to the trend of curling, the sheet S is held by the guide 25 and hindered from excessive movement in the exhausting direction owing to the slope 24. Thus the sheets S are loaded under a sensing piece 22 so as to enhance the sensing accuracy. In case sheet(s) S having a strong trend of curling accommodated in the chamber 17 is pushed by another sheet S which is collected afterward and has a weak trend of curling as willing to go straight, the first named sheet S is inverted upward by the slope 24 to permit the following sheet S to be collected.  Thereby jamming risk is precluded and the bottom area of the sheet collecting chamber can be reduced.
