Title: Thread detector in sewing machine
Inventor: SHIBATA YOSHIO
IPC: D05B59/02
Filed: 1987-09-12
Abstract: PURPOSE: To detect the existence of a thread without forcing it to be mechanically burdened by grasping presence or absence of the fluctuation of an electric charge which occurs in a detection electrode owing to the horizontal shake of the thread as against a needle location hole. CONSTITUTION: The detection electrode 22 is circularly formed along the peripheral edge of a thread carrying through hole 21 and a timing signal generating means 5 generates a timing signal by synchronization with the vertical movement of a needle 3 in case the thread to be detected exists inside the detection electrode 22 in a sensor 4. When a body 32 to be detected is rotated by the rotation of a main shaft 31 in the sewing machine, a proximity detecting signal is given to a timing signal generating circuit 34 whenever the body 32 approaches an proximity sensor 33 and the timing signal is outputted. Then a judging means 6 judges the existence of the fluctuation of a voltage signal by receiving the voltage signal from the sensor 4 and the timing signal from the timing signal creating means 5 and outputs a thread absence judging signal in case of no fluctuation in it.  The judging means 6 is constituted of an amplifier part 35, a timing circuit 36 and a comparing circuit 37 and a stop control means 7 stops a motor for driving the main shaft of the sewing machine when it receives the thread absence judging signal (thread breakage signal) from the judging means 6.

IPC: G01L9/04
Filed: 1989-09-05
Abstract: PURPOSE:To prevent the breakdown of a semiconductor pressure sensor due to hydraulic surge by providing a surge pressure buffer device at a hydraulic pressure introducing hole in the vicinity of the semiconductor pressure sensor. CONSTITUTION:An orifice plate 10 is provided at a chamber 11 which is expanded at the inlet part of the introducing hole of a housing 5 and the inlet side of the chamber 11.

Title: Screen printing method
Inventor: TANAKA YUKIO
IPC: B41F15/08
Filed: 1992-08-28
Abstract: PURPOSE:To permit maintaining the thickness of film of printing ink stably at a desired value at all times by a method wherein the strain of a squeegee is measured by a strain gauge and the pressure of the squeegee is controlled based on the result of measurement. CONSTITUTION:When a strain gauge 18 inputs the result of measurement, a microcomputer 20 operates a pressure applied on a squeegee rubber 16 and the angle theta of the rubber 16 based on the amount of measured strain. When the pressure is larger than a desired value and the angle theta is smaller than a desired value, the computer 20 controls a solenoid valve control circuit 24 so that the solenoid valve of a regulator 26 is closed whereby compressed air, outputted from the regulator 26, is weakened. Then, a force to push down a squeegee rubber retaining jig 12 in an air cylinder 14 is weakened whereby the pressure applied on the rubber 16 is reduced and the angle theta is increased. On the other hand, when the pressure applied on the rubber 16 is smaller than a desired value and the angle theta is larger than the desired value, the pressure impressed on the rubber 16 is increased and the angle 8 is decreased. According to this method, the thickness of film of the printing ink can be kept constant.

Title: Improving method for adhesion strength of polyoxymethylene highly oriented material
Inventor: IGARASHI TSUNEO
IPC: C08J5/12
Filed: 1985-10-17
Abstract: PURPOSE:To provide a method of bonding strongly between polyoxymethylene oriented materials or between polyoxymethylene oriented material and the other material, by roughening and napping the surface of the polyoxymethylene oriented material. CONSTITUTION:In bonding between polyoxymethylene highly oriented materials whose tensile modulus is more than 10 Gpa or between the polyoxymethylene highly oriented material whose tensile modulus is more than 10 Gpa and the other material, simultaneously with previous roughening of the surface of said polyxymethylene highly oriented material adhesion treatment is performed after napping.

Filed: 1988-09-16
Abstract: PURPOSE:To reduce the number of communication cables by providing a means to connect a communication control unit to plural radio units with a multiplex transmission path and to transit/receive to multiplex the voice signal and the control signal of the radio unit. CONSTITUTION:The communication control unit is connected to the radio unit with the multiplex transmission path to transmit/receive to multiplex the voice signals and the control signals of the same number of radio units as that of radio units connected to the transmission path.

Abstract: PURPOSE:To suppress system-down as less as possible by changing sequentially control information of a control information register and performing single diagnosis and combined diagnosis of each processing unit to make the diagnostic expansion from the basic operation to the relating operation of the processing unit possible. CONSTITUTION:When the single test of a centralized control section 31 is finished, a service processing unit 3 gives interruption to an input/output processing unit 1. The unit 1 receiving it sets a control information register 32 to ''001''. Thus, a transmission/reception drive control circuit 11 is made effective to attain the diagnosis of the processing unit 5. Then the interlocking test with the unit 5 is attained from the unit 1 to the control section 31. Similarly, the register 32 is set to ''010'' and ''100'' to conduct the test of processing units 6, 7 sequentially. Furthermore, the register 32 is set to ''011'' to conduct the combined test of the units 5, 6 by using the control section 31 as the center. Thus, the content of the register 32 is changed to change the combinations of the control section 31 and the units 5-7 in this way and various combined tests are conducted by expanding sequentially the diagnostic area.
