Title: Secondary chopper controller for wound-rotor type induction motor
Inventor: KUGE KATSUTAROU
IPC: H02P25/26
Filed: 1984-05-24
Abstract: PURPOSE:To set the secondary loss of an induction motor substantially to zero at operating time by connecting a diode and a capacitor in parallel with the secondary current control chopper, and connecting a starting resistor in parallel with the capacitor at the starting time to regenerate power after the starting is completed. CONSTITUTION:A rectifier SR is connected with the secondary winding of a wound-rotor type induction motor M, the DC output side of a rectifier is intermittently shortcircuited by a chopper circuit GTO to control the secondary current. A circuit which has a diode D and a capacitor C connected in series is connected in parallel with the chopper GTO, a starting resistor R is connected in parallel with the capacitor C at the starting time, and the resistor R is disconnected from the capacitor C after the starting is completed. Thus, power charged in the capacitor C is regenerated to an AC power source through a filter having a reactor L and an auxiliary capacitor CA and an inverter GIV to reduce the secondary loss, thereby operating in high efficiency.

Title: Loop transmission system
Inventor: SHIMIZU SHIYOUICHI
IPC: H04B10/27
Filed: 1981-07-01
Abstract: PURPOSE:To detect the occurrence of disconnection of a transmission line by starting a timer for data transmission, and measuring the time until data is returned from a loop transmission line. CONSTITUTION:A terminal A which serves as a master station during system actuation issues a command packet once powered up, and also starts its incorporated timer. Then, the length of a transmission line and the time required by data to pass through respective terminals are known previously, so when this known time is shorter than the time when said command packet returns to the terminal A through the loop transmission line and respective terminal stations, it is judged that the loop transmission line is broken. The terminals B, C and D also start the clocking of their own timers once powered up, and judges that the transmission line is disconnected unless the command packet from the terminal A arrives at respective stations within scheduled times.

Title: Semiconductor device
Inventor: TOBINAGA YOSHIICHI
IPC: H01L21/60
Filed: 1980-07-29
Abstract: PURPOSE:To make the bonding on resin films highly reliable, by forming a metal pattern having the surroundings covered with the second polyimide film on the first polyimide film on a metal layer, and forming a pad metal on the metal pattern through a polycrystalline Si layer. CONSTITUTION:For example, on a substrate 1 having an Al wiring 2 of the first layer, liquid polyimide is applied, heat-treated and hardened to form a first polyimide resin film 3. An Al pattern 14 of the second layer is formed on the pad, and then polyimide is applied to the pad. This is prebaked at about 90 deg.C, and the opening connected to the Al pattern 14 is formed by photoetching. After this has been hardened and baked (300-500 deg.C), a polycrystalline Si layer 7 and an Al layer 8 are formed and heat-treated to obtain ohmic contacts. Subsequently, a wire 9 is bonded to the Al film 8. Thus, the second Al layer 14 can be bonded onto the resin films 3, 5. Because they are alloyed with the upper Al film 8 and the polycrystalline Si layer, separation or the like can be prevented after bonding.

Title: Crossing arm-type elevating device
Inventor: HANSU NUSUBAUMU
IPC: B66F7/08
Filed: 1993-04-30
Abstract: PURPOSE: To further lower the lowest position by a method wherein a lever member which raises cross-arms consisting of a pair of arms which cross each other in an X-shape and are in a nearly horizontal posture when a receiver is in the lowest position by the driving force of a driving means is attached near the cross point of the cross-arms. CONSTITUTION: When a receiver 4 is in a lowest position, if a cylinder device 8 is driven to expand, first, a lever member 5 is turned clockwise relatively to a 2nd arm 2 around a fulcrum 6 and a downward force is exerted on a pressing member 9 of a 1st arm 1 at the lower acting face of the lever member 5. By the force, the cross-arms 1 and 2 in a horizontal posture are raised and the receiver 4 starts ascending. When the receiver 4 reaches an intermediate height, the left end of the lever member 5 is pressed against a stopper 10 attached to the 2nd arm 2 and, if the receiver 4 further ascends, the lever member 5 functions only as a support point of the piston side of the cylinder device 8 and the 2nd arm 2, so that the cross-arms 1 and 2 are directly turned and the receiver 4 is made to ascend to the highest ascending position.

Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To simultaneously improve the dynamic loft and the stability at the time of impact by a method wherein the visible layer of a belt comprises at least one high density material and contains an arch-shape part which forms a peripheral mass body, and the arch part is extended from the heel to the toe. SOLUTION: A belt (band-shaped part) 4 is formed of an upper part 6, a lower part, and a strip 8 (an arch-shape part to form a weight) 8. At locations where both ends of an impact surface 2 come into contact with the belt 4, a heel 9 and a toe 10 are formed. The strip 8 is formed of a high density material such as copper, and adds weight to a head 1. By this constitution, the side parts of the strip 8 being close to the heel 9 and the toe 10, generate a stabilization effect during a turning of the head 1 regarding the vertical directional axis at the moment of a ball impact. By this method, the accuracy of the projectile path of a ball is improved.

Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a heating element capable of highly precise temperature control which is used for a plane paper copying machine, a laser beam printer or a toner fixing device by using a thick film NTC thermister as a thermister. SOLUTION: A thick film NTC thermister 26 is provided between a pair of thermister electrodes 25 and electrically connected to the thermister electrodes 25. The thermister 26 is formed by adding boro-silicate lead glass and metal component with a low specific resistance or metal oxide additive to either Mn, Co, Ni or Mn, Co, Cu. In this way, the thermister constant of the thick film NTC thermister 26 is no less than 3000 Kelvin and so a resistance value is greatly changed with a temperature change in operation. As a result, a well sensitive heating element can be obtained. Connection between the thermister electrodes is made by a wide connection to allow the heating element to be easily manufactured without projections.

Filed: 1981-07-06
Abstract: PURPOSE:To compensate the span fluctuation with high accuracy over a wide range of the exciting frequency and without using any RC delay circuit, by using a microcomputer for the signal process and compensating the span fluctuation with an operation. CONSTITUTION:The span compensation degree alpha due to the type of a transmitter based on its caliber, etc. and the exciting frequency is obtained previously and stored in an ROM12. Then a CPU11 reads the degree alpha out of the ROM12 based on the designation of selection for the caliber of the transmitter via a setting switch 16 and the frequency of a power supply 8 which is measured by a frequency counter 17. Thus the correct flow rate value is obtained from V0= Vs/alpha to the measured flow rate value Vs. At the same time, the frequency (f) of the using mode is counted by the counter 17 and stored in an ROM14. The selection of the transmitter caliber is designated by the switch 16, and the corresponding compensation data beta and gamma are read out of the ROM12. Then the CPU11 calculates the correct flow rate value V0 from V0=Va/[beta+gamma(f-f0)]. This result can be converted into an analog signal through a D/A converter 13 and then delivered.
