Title: Center presser bar mechanism for sewing machine
Inventor: IMAI TSUTOMU
IPC: D05B39/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To simplify center presser mechanism of a cycle sewing machine capable of providing seams along an optional shape within a specified range of material to be sewn. SOLUTION: Center presser mechanism has a center presser vertical moving part 20 lowering a center presser 12 during sewing and raising it during stop, and a center presser sewing action part 30 for vertically moving the center presser 12 in correspondence with a needle during sewing. The motion of the center presser vertical moving part 20 and center presser sewing action part 30 for vertically moving the center presser 12 is transmitted to the center presser 12 by one center presser link 40. The center presser sewing action part 30 has a center presser cam 31 provided at an upper shaft 3, and a center presser driving arm 32 to be a follower of the center presser cam 31. The center presser cam 31 can retreat backward along the upper shaft 3 from a contact position with the center presser driving arm 32.  The center presser cam 31 is retreated and separated from the center presser driving arm 32 to stop the vertical motion of the center presser 12 during sewing.

Patent JP-2000252551-A (JP)
Title: Laser apparatus
Inventor: IMAI SHINJI
IPC: B23K26/066
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent break of a shutter or deterioration and damage to components within the apparatus. SOLUTION: A control circuit 9 outputs an activation signal D to a drive circuit 8 before driving a laser oscillator 2. In response to a signal D, the circuit 8 outputs an activation current which is a DC current and thereafter a holding current which is a pulse current to a rotary solenoid 6. As a result, the solenoid 6 is excited to thereby move a shutter 5 to an opening position and hold the shutter 5 there under a power-saving state, whereby a radiation window is opened. By driving the oscillator 2 under this state, a laser beam is radiated from the window. When the holding current is reduced to thereby cause the shutter 5 to get out of the opening position, a photo interrupter 7 detects such a state. Thus, the circuit 9 outputs the signal D again. As a result, the shutter 5 is moved to return to the opening position immediately.

Title: Motor power steering device
Inventor: KOIKE ICHIRO
IPC: B62D5/04
Filed: 1985-03-13
Abstract: PURPOSE:To prevent unintended power steering under abnormality in the steering signal system by prohibiting power steering upon deviation of the level of signal to be produced with correspondence to the steering from specific range. CONSTITUTION:Upon breaking of the output signal line of steering force sensor 2 under steering, the output of a voltage converter 14 will go to low level thus to feed out 0 level signal from a comparator 13a. Consequently, the outputs from AND gates 27y, 27u-27x will all go to 0 level to turn off all transistors 4a-4d thereby current is not fed to a power steering motor 7 thus to disable power steering. Upon fault of said power converter 14, large voltage is produced to provide 0 level signal from the comparator 13d thus to prevent current supply to the motor 7.

Abstract: PURPOSE:To automate the manufacture process by providing a cancel coil consisting of a printed board having copper foil printed pattern wiring in a deflecting yoke, in which a horizontal deflecting coil and a vertical deflecting coil are wound up onto a flared bobbin. CONSTITUTION:A flexible cancel coil 9 is installed by an adhesive and the like along a screen side opening part of a deflecting yoke 10, in other words, along a flange part of a wide diameter side of a bobbin 1. Spiral patterns 9a, 9b in both ends of the coil 9 are placed in vertically symmetric arrangement in the Y-Y direction setting a center axial line Z-Z of a cathode ray tube as the center so that magnetic fields in the equal direction are generated. Plural taps are arranged in the middle of a copper foil printed pattern and regulation of the inductance of the coil 9 is carried out by short-circuiting between appropriate taps. In this way, winding and wiring of the coil is dispensed with or simplified, so that material, equipment, and a man-hour, are reduced while size reduction and automation of the device is enabled.

Title: Dampening-waterless planographic printing plate material
Inventor: MATSUBARA SHINICHI
IPC: G03F7/00
Filed: 1990-02-27
Abstract: PURPOSE:To provide the easily visible printing image part after dyeing and to substantially prevent the generation of fogging in spite of the conduction of an exposing operation under a white fluorescent lamp by providing a primer layer, a photosensitive layer and a silicone rubber layer in this order on a base and incorporating a 1, 2- naphthoquinone-2-diazide-4-sulfonate compd. into the photosensitive layer. CONSTITUTION:The primer layer, the photosensitive layer and the silicone rubber layer are provided in this order on the base and the 1, 2-naphthoquinone-2-diazide-4- sulfonate compd. is incorporated into this photosensitive layer. The photosensitive layer contg. the 1, 2-naphthoquinone-2-diazide-4-sulfonate compd. is less yellowish, i.e., the appearance of the plate material itself is less yellowish. The blue color of the printing image part is, therefore, easily visible in the relation with the appearance of the plate material itself when the printing image part is dyed blue. Since the absorption wavelength of the plate material is on the short wavelength side, the plate material is hardly sensitive to the light of the white fluorescent lamp. The image after dyeing is easily visible in this way and is hardly sensitive to the light of the white fluorescent lamp. The generation of the fogging is substantially prevented.

Abstract: PURPOSE:To replace a worn tip without removing a band saw from a drive mechanism by arranging a flexible fitting body on the main body of the band saw and engaging a tip supporting base fixed with diamond or the like relatively displaceably and removably. CONSTITUTION:Slits 17 are notched between teeth 15 of a band saw 13 to remove stress, discharge chips, and prevent heating; a tip supporting base 23 fixed with a hard tip 19 at the tip is engaged with a fitting body 21 which is welded to the teeth 15 and formed with spherical coupling sections 25.

Abstract: PURPOSE:To determine the position of a toroidal surface accurately and quickly when the entire surface is measured by mounting a body under test on a rotary stage, forming interference fringes in parallel with one of principal meridians which are orthogonally intersected on the toroidal surface as a surface under test, and scanning the interference fringes along the other principal meridian. CONSTITUTION:A rotary stage 8 rotates a body under test 7 having a toroidal surface 7a along either of principal meridians which are orthogonally intersected. A means 8b supports the body under test so that the body under test is freely moved in the directions of the axes of (x), (y) and (z) which are orthogonally intersected one another. A position detecting light source emits the light from a light source 1 for coherent light which is directed toward a rotary center O of the rotary stage through a half mirror 19, a mirror 13, an optical isolator 14 and a mirror 15. The light is split through the half mirror 11. The light is cast on the toroidal surface 7a. A convergent lens 9 and a screen 16 focus the image of the reflected light from the toroidal surface. This apparatus is composed of these parts. The position of the body under test 7 is determined so that the incident light and the reflected light at the toroidal surface agree.
