Title: Wire rod wound synthetic resin bobbin
Inventor: NAKAJIMA NORIHIRO
IPC: B65H75/14
Filed: 1994-05-27
Abstract: PURPOSE:To enable a bobbin to be molded by a compact molding machine and easily economically produced by providing a plurality of reinforcing sheets positioned circumferentially at equal interval and fixed on both longitudinal ends to the outer peripheral part of a circular side plate. CONSTITUTION:At least a circular side plate 5 is constitutionally divided into a plurality of divisional side plate parts 50, so that a compact molding machine will suffice for molding the circular side plate while molding metal molds can be miniaturized to reduce the metal mold manufacturing cost. Also, reinforcing sheets are attached to the circular side plate 5 circumferentially at equal interval and fixed on both longitudinal ends to the outer peripheral part of the circular side plate 5, so that the reinforcing sheet will function as a tension support member. Thus, the reinforcing sheet itself can be composed of a thin plate material. Also, since the circular side plate is supported by the reinforcing sheet, the circular side plate 5 is thinned.

Title: Watt-hour charge meter
Inventor: TSUDA ZENICHIROU
IPC: G01R11/06
Filed: 1981-07-22
Abstract: PURPOSE:To determine the sum of energy charge and demand charge simply by modification of a part of an existing instrument by providing a current squaring coil and a short circuiting piece to the circuit for a part of the voltage magnetic flux flowing in parallel with a main voltage magnetic flux. CONSTITUTION:When a voltage is applied to a voltage coil 2, a voltage magmetic flux phi0 passes through the voids of a voltage iron core 1, and flows cyclically in the iron core 1 around the coil 2. A voltage magnetic flux phi1 cuts a rotary disc 9 from the central side of the core 1, passes through a current iron core 3 and an iron core assembling yoke 5 in series and flows to the parts on both sides of the core 1. A voltage magnetic flux phi2 cuts the disc 9 and flows to an iron core counter electrode yoke 6 provided with a current squaring coil 7 and a short circuiting copper plate 8. Since the magnetic flux generated from the coil 7 cuts the disc 9 in the same place as that of the flux phi2, said magnetic flux acts upon the current magnetic flux and generates the couple of force proportional to the square of the current in the disc 9. The disc 9 rotates at the speed proportional to the sum of said couple of force and the couple of force proportional to electric power.

Abstract: PURPOSE:To keep both an inlet side tension and an elongation percentage constant and to perform a stable elongation percentage rolling by adding a rolling load correction by a correction load corresponding to speed variation to a rolling load control depending on tension variation in the inlet and outlet sides of a mill. CONSTITUTION:A hydraulic draft controller 9 controls a draft load PR by converting a comparison difference DELTAT between a detected tension TME by a bridle roll 4 of a skin pass mill 3 and the inlet side tension reference value TMEref into a load difference DELTAP by a tension/load converter FG1. A speed control 10 is performed by converting a comparison difference DELTAT between a detected tension TMD by a bridle roll 2 and the outlet side tension/reference value TMDref into a speed difference DELTAS by a tension speed converter FG2. In that time, a pressure difference DELTAPR by a corrector FG3 converting speed variation into load variation is added to a draft force control 9. Variations in the inlet side tension TME are reduced to keep the inlet side tension constant and to perform the stable elongation percentage rolling. Also, conversion FG4 of a draft force correction value DELTAPR into a speed and addition of the conversion to the speed control 10 is performable.

Filed: 1977-09-26
Abstract: PURPOSE:To reduce the cost and increase the efficiency by boosting the intermediate output of dividing circuit to supply to the driving circuit of a step motor and thinning down the motor coils to miniaturize the motor. CONSTITUTION:An oscillation circuit 1 and dividing circuit 2 are respectively operated by a battery 11, and a driving circuit 3 is supplied with output obtained by properly boosting the intermediate output of dividing circuit 2 by means of a boosting circuit 7. That is, coil 10 of a step motor 4 is applied with boosted line voltage which is alternately inverted. Therefore, the resistance of coil 10 to obtain the conventional ampere-turn may be large, so that thinner wires than usual may be used for the coil. Moreover, since the size of coil 10 may be smaller than usual and, if the wire thickness is the same, the coil may be wound in many layers in the same position, the length of coil 10 may be shortened. Hence, the size of stators 5, 6 may be also smaller. In addition, since the magnetic path is shorter, the magnetic resistance may be smaller, hence the efficiency improved.

Abstract: PURPOSE:To enable ejection even when a main switch is turned off, by connecting a switch, operated at the time of loading and unloading of a cassette, directly to a battery and by interposing a timer switch circuit between the switch and a motor. CONSTITUTION:When a cassette is loaded while an engine key S2 is in the ON state, a switch S1 is turned on and the transistors (TR) Q1 and Q2 of a timer switch circuit 2 turn on to supply electric power to a motor 3. At ths time, TRs Q3 and Q4 are in the off state and a plunger 4 is not driven. When the cassette is loaded while the engine key S2 in the OFF state, on the other hand, the switch S1 is turned on to charge a capacitor C2 through a capacitor C1, so the motor 3 is conducted; and a TRQ5 is in the off state while TRs Q3 and Q4 are turned on, so a plus pulse appears at the collector of the TRQ3 to turn on both TRs Q6 and Q7, then plunger 4 is conducted. Consequently, a trigger mechanism is actuated to drive an ejection mechanism by utilizing the revolution force of the mtor 3.

Title: Hydraulic pressure assistor
Inventor: OKANO KUNIO
IPC: B62D5/07
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To certainly accumulate specified hydraulic pressure in an accumulator for emergency by, accumulating even hydraulic pressure other than the hydraulic pressure generated by actuation of first and second hydraulic pressure assistors. SOLUTION: When an on signal of an ignition switch 34 is input to an ECU 33, the ECU 33 switches and sets a flow control valve 32 over to a flow control position II for a specified period of time. Consequently, as a flow rate of working liquid flowing in a PS passage 31 is limited, hydraulic pressure is generated on the upstream side of the flow control valve 32, and this hydraulic pressure is accumulated in an accumulator 11 for emergency. Consequently, the hydraulic pressure of the accumulator 11 for emergency rises. Accordingly, for a specified period of time after the ignition switch 34 is switched on, the hydraulic pressure is accumulated in the accumulator 11 for emergency even if brake operation and steering operation are not carried out. Consequently, it is possible to certainly accumulate further sufficient hydraulic pressure in the accumulator 11 for emergency.

Abstract: PURPOSE: To enable changing of a letter type and a print-carriage pitch, by a method wherein, through the drive of a carriage by a servo-motor, a head discriminating circuit which discriminates the head being different in a letter type, and in case head is different from a letter to be printed, head-replacing and carrying of print corresponding to the replaced head are performed.  
     CONSTITUTION: The head discriminating circuit 9 discriminates the letter type in a thermal head 6, and the letter type is compared with details of an RAM11. If the  two coincide with each other, printing is conducted using the head 6. In case the  two do not coincide, an alarm is producted, and an output from a head coincidence  circuit 12 turns off a motor drive circuit 1 to suspend running of a servo-motor. If  an operator attaches a thermal head, being different in the letter head (for example, 12-point), the head discriminating circuit 9 discriminates the head which is compared with the storage in the RAM11. This releases an alarm and causes rotating of the servo-motor 4 at a speed corresponding to the thermal head to move a carriage 5.
