Title: Method of controlling linear synchronous motor
Inventor: WATANABE ASAKI
IPC: H02P7/00
Filed: 1979-07-13
Abstract: PURPOSE: To prevent the imbalance among currents flowing through a feeder and the occurrence of a current through a neutral line, by energizing a ground coil placed on the ground in the moving direction of a vehicle, so that the sum of currents flowing at respective phases is always zero.  
     CONSTITUTION: A position detection signal based on the positional relation between a superconductive magnet on a vehicle and a coil on the ground is applied to a receiver 81 through antennas 16, 7. Only one of the three phase signals is received so that a pulse width prediction unit 91 predicts a falling signal on the basis of a rising signal. A sine wave generator 101 generates sine waves of respective phases on the basis of a prediction signal from the prediction unit. The output of the sine wave generator 101 and a signal, which is produced by a comparator 14 which compares a predetermined speed with a real speed applied from a speed calculator 13, are entered into a multiplier 11 to energize the ground coil through a power converter 12. As a result, the sum of the instantaneous values of respective phase currents can be always kept zero to prevent the occurrence of a current through the  neutral line of a feeder.

Title: Apparatus for supplying material
Inventor: UCHIDA SHIGEO
IPC: B29C48/03
Filed: 1986-04-18
Abstract: PURPOSE:To supply polyethylene pellets at a specified mixing ratio in an extrusion machine, by supplying multi-kinds of polyethylene pellets quantitatively from separated supplying holes. CONSTITUTION:The first material is put into a hopper 3 and the second material is supplied into a pipeline path 4 from a supplying hole 5 of the second material by means of a quantitatively supplying apparatus 8. Because the first and the second materials can be separately supplied, each material can be surely supplied at a specified mixing ratio to a material supplying hole 2. Moreover, because the pipeline path 4 is made of a perforated iron plate with holes whose upper end is open and lower end has an air vent 6, even if air flows backward from an extruder 1, the air an be effectively released. Because the upper end of the pipeline path 4 is bent downward to open its hole in the downward direction, the first material does not go into the pipeline path 4 when the first material is cast into the hopper 3.

IPC: G01N21/35
Filed: 1992-02-25
Abstract: PURPOSE:To measure gas concentration highly accurately by finding a measurement output after concentration of measurement gas is measured under a pressure higher than one atmospheric pressure, and finding a reference output after the gas is substituted with external air speedily afterwards. CONSTITUTION:Measurement gas is introduced into/substituted in a gas cell, and a discharge valve is closed, and a gas pressure is raised. When the pressure reaches a certain pressure A higher than one atmospheric pressure, the introduction is stopped, and outputs of an infrared sensor 5 are sampled in this condition for a constant time by means of a selector 15, and the outputs are stored in a memory 16, and an operation 17 is carried out on an average value S of measurement outputs. Next, the gas in the gas cell is substituted with external air, and the pressure in the gas cell and the outputs of the sensor 5 are decreased rapidly. When the pressure is lowered to the first pressure, a pressure sensor 13 is operated, and the outputs of the sensor 5 are sampled for a constant time by means of the selector 15, and these values are stored in a memory 18. An operation unit 19 carries out an operation on an average value N of a reference output from these values, and an operation unit 20 carries out an operation on an output S/N. Gas concentration can be found from this operation result.

IPC: H02M7/48
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a power unit which can reduce higher harmonics from input currents, can reduce the pulsating current flowing to a load, and has a circuit configuration containing a less number of parts. SOLUTION: A capacitor C2 connected between the DC output terminals of a rectifier 2 has a relatively small capacitance and forms a resonance circuit together with the primary winding of a transformer T1 . When first and second switching elements Q1 and Q2 connected in parallel with a smoothing capacitor C1 are alternately turned on/off, an electric current flows. Therefore, the both- terminal voltage Vc2 of the capacitor C2 drops to about 0 V even in a near section in which the power supply voltage Vs of an AC power source 1 nearly becomes zero, and it becomes possible to take in an input current Iin over the full period of the power supply voltage Vs of the AC power source 1.

Title: Method for recognizing lead position
Inventor: USAMI TAMOTSU
IPC: H01L21/60
Filed: 1981-06-12
Abstract: PURPOSE:To perform position recognizing work highly efficiently and highly accurately by projecting the image of an entire lead on one picture screen, and moving the lead or a TV camera by the approximate distance corresponding to the width of the lead. CONSTITUTION:The image of the entire lead 1 or the post parts of all the leads are projected on one TV screen 6. When the entire lead is projected in this way, each lead is projected in a small size. With respect to the lead width of 130 + or -30mum, the bit size for position recognition becomes 50-100mum. Therefore, the size of the bit 8 may become larger than the lead width, and detection of the lead position is difficult under this state. An X-Y table is moved in respective directions. The ratio of the overlap of the post part 2 and the bit 8 changes when the table is moved in the direction of the lead width. Accordingly, the output of the bit 8 changes. That is, when the post 2 and the bit 8 begin to overlap, the output is gradually increased. When they are completely overlapped, the output becomes the maximum. When the table is moved and the part where they are not overlapped appears on the opposite side of the bit, the output is gradually decreased.
