Title: Welding method for stud bolt
Inventor: KURATA RYUJI
IPC: B23K9/20
Filed: 1989-03-03
Abstract: PURPOSE:To obtain stable and high weld strength by forming and reworking the welding zone in the head part of a stud bolt and removing a surface treated layer prior to stud welding. CONSTITUTION:The stud bolt 1 is fed pneumatically from a feeder to a cutting device via a feed hose. The welding zone 1a of the stud bolt 1 chucked to a piston rod 23 comes into contact with the cutting edge of a cutting tool 33 and pushes down the tool 33 by overcoming the energizing force of a spring 35 until the flange 1c of the bolt 1 comes into contact with the base of a recess 31a. The cutting tool 33 is rotated via a revolving shaft 32 by an air driving source and the surface of the weld zone 1a in the head part of the bolt 1 is cut by the cutting edge, by which the removal of the plating layer and the reworking of the shape shear drop of the pointed part are executed. Air is thereafter blown from an inlet 37 in order to remove the shavings generated from the surface in the welding zone 1a of the bolt 1. The shavings are thereby discharged from an outlet 38 to the outside. The stud bolt is then fed to a stud gun by the air.

Title: Parking facility
Inventor: KANAI KENZO
IPC: G07B15/00
Filed: 1991-03-15
Abstract: PURPOSE:To easily construct and install a parking space without digging the ground so deeply by providing a scotch link caused to rise and fail only by the horizontal expansion and contraction of an advance and retreat rod, a vehicle detector, a toll adjustment timing device and a parking meter. CONSTITUTION:When an automobile enters a marking space S, a vehicle detector 2 buried in the ground detects the automobile and sends a close signal to a toll parking meter 3. The meter 3 sends a close signal to a departure stopping machine 1 to expand an advance and retreat rod buried substantially horizontally in the ground, so that a scotch link 12 is lifted up to check an automobile from getting out. When a designated toll is put in a coin timer 31, the timer 31 sends an adjustment signal to the meter 3. The meter 3 outputs an open signal to the departure stopping machine 1 to lodge the scotch link 12 through the advance and retreat rod, so that the automobile can be allowed to get out. Thus, even in case of a place where underground piping is complicated, the parking apparatus can be installed without digging the ground not so deeply and without being restricted by such a place condition.

IPC: B32B38/00
Filed: 1990-03-03
Abstract: PURPOSE: To mutually bond sheet materials by bringing the sheets together and heating the assembly obtd. until at least one of the sheets reaches a temp. at which it will adhere to the adjacent sheet. CONSTITUTION: Several winds of a metal foil 27 are wound on a center 31 to ensure good electric contact between the metal foil 27 and the center 31. A plastic sheet 28 is wound on the metal foil 27 while it is brought into close contact with the metal foil 27. The sheet 28 is passed through between an earth roll 37 and a thin electrode rod 38 to feed a DC there. The metal foil 27 is heated by this electric current at a temp. so as to melt the plastic sheet 28 there. A computor means of a power supply source detects the DC voltage and the electric current and calculates the value of resistance of the electric current from these data. When the temp. required for the metal foil 27 reaches a temp. for achieving a sufficient bonding to the plastic film sheet 28 by the calculated value of resistance, the DC electric voltage is decreased to zero to prevent a roll 30 from being superheated.

Abstract: PURPOSE:To continuously display the remaining time of a drying operation to be changed corresponding to the drying process of the clothes dryer. CONSTITUTION:When the operation of an operation switch 31 is detected, a microcomputer 3 executes the drying process by igniting a burning device 20, driving a motor 19 and driving a rotary drum and an exhaust fan. Temperature increasing speed is calculated from an exhausted air temperature detected by a temperature sensor 27, and required drying time is decided and set on a display 4. Then, the display time of the display 4 is subtracted and displayed with the passage of time together with the proceedings of drying. When the final drying process for fixed time is started, the display is switched to final remaining time display. When the final drying process is not started even after predictive remaining time is turned to this fixed time, this fixed time is fixed. Then, it is subtracted and displayed with the passage of time together with the start of the final process and, when it is turned to '0', the operation is finished.

The threshold voltage of the MOS transistor is set to a sufficiently low value before the differential amplifier 101 starts to operate by well potential control, and the threshold voltage is maintained after the operation has started. Thus, a high-speed sensing operation is made possible, and sensing operation margin is improved.

Title: Flow rate control valve with reversible ac motor
Inventor: SARUHASHI KOICHI
IPC: F16K31/04
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To simplify control over a flow rate of fluid passing through a pipe passage and reduce a cost of facility by a method wherein an operating member for operating a valve element in an opening or closing direction in response to a desired reciprocating motion and a reversible AC motor for driving the operating member are provided. SOLUTION: A reversible AC motor 7 acting as a driving source is used. When a valve driving shaft 5 is moved in a direction indicated by an arrow A, a valve fitting member 2 fixed to the valve driving shaft 5 is also moved in a direction indicated by an arrow A and a clearance between the valve fitting member 2 and the valve 1 is expanded. With such an arrangement as above, a desired pressure is received in a flowing direction indicated by an arrow B, much amount of hot water accumulated and stayed at a region 18A passes between the valve fitting member 2 and the valve 1. Subsequently, the hot water passes within the valve fitting member 2, reaches the region 18C and flows in a direction indicated by the arrow B.  In turn, as the valve driving shaft 5 is moved in a direction opposite to the arrow A, the valve fitting member 2 is also moved in a direction opposite to the arrow A, a clearance between the valve fitting member 2 and the valve 1 is made narrow to cause a flow rate of hot water within a pipe 18 to be reduced. The aforesaid processing is continued to enable a temperature of the hot water to be kept near the set temperature.
