Title: Controller for resistance welding machine
Inventor: HACHIMAN TAKASHI
IPC: B23K11/24
Filed: 1980-04-08
Abstract: PURPOSE: To obtain high quality welding by detecting welding current in the secondary circuit of the welding transformer and compensating the excitation loss of the welding transformer.  
     CONSTITUTION: When input is made from a welding start switch 29 to the control section 31 of a control device, a welding gun pressurizing signal 40 is sent out and all of welding guns 19aW19f apply pressure to the material to be welded. At the same time, a welding circuit selection signal 41 is sent out from the control section 31 and a switch 25a-4 is closed to form a welding circuit. After lapse of pressurizing time stored in the storage section 30, a digital value corresponding to stored set current value is sent to a current setting section 32 to start welding. The welding current is detected by a current transformer 20a and controlled by the control device to become equal to the set current. When the welding cycle of the welding gun 19a reach the set cycle, ignition pulse of a thyristor 16 is stopped, the welding current is cut off, the switch 25a is opened and the switch 25b is closed to form the next welding circuit.

Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain images having a good contrast. SOLUTION: The transmitted light or reflected light of a sample 19 irradiated with the light entering from a light source 12 is photoelectrically converted by a photoelectric conversion circuit 36 which in turn outputs a photoelectric conversion signal.

Title: Laser beam machining head
Inventor: SHIRASU KOZO
IPC: B23K26/08
Filed: 1990-02-26
Abstract: PURPOSE:To reduce the transmission loss of a laser beam and to increase its output by rotating the reflection surface inclined at a specified angle of a rotating mirror to reflect the laser beam and allowing the laser beam condensed by a condensing element to carry out scanning of circular motion. CONSTITUTION:Since the laser beam 1 is made incident on the reflection surface of the rotating mirror 11 and the reflection surface is inclined by an angle theta-with respect to the vertical surface of a rotation axis of a rotation driving part 12, when the rotating mirror 11 rotates at high speed, the laser beam 1 reflected on the reflection surface is made incident on a parabolic mirror 13 while being rotated at a rotation angle 2gamma. Since the reflection surface of the parabolic mirror 13 is formed into the paraboloid of revolution, the laser beam 1 reflected thereon is condensed on the local surface of a member 6 to be machined and projected while carrying out scanning of circular motion. Consequently, the transmission loss of the laser beam is reduced and the laser beam is condensed compactly and its output can be increased.

Title: Cooling device for molten polymer sheet
Inventor: TAKAGI NORIO
IPC: B29C48/08
Filed: 1986-03-05
Abstract: PURPOSE:To restrain the rolling of air and increase the speed of casting by a method wherein a specified groove is provided on the cooling surface of a drum to make the breathing resistance of the surface lower than a specified value. CONSTITUTION:The title cooling device is provided with a cooling drum, cooling and solidifying a sheet-type molten polymer extruded form, extruded out of a extruding die. The cooling surface of the drum is capable of adhering the molten polymer extruded form and is provided with a groove having the width of 0.1-39mum in a direction parallel to the circumferential direction of the drum or in a direction having an acute angle with respect to said circumferential direction so as to interest with a straight line of 10mm which is drawn in the axial direction of the drum at least at 5 points and the total length of the groove, superposed with the straight line, becomes 7mm. The breathing resistance of said surface is 20,000 seconds or less when it is measured by vacuum leakage method. When the opening width of the groove is up to 0.1mum, clogging is readily caused by low molecular weight compound subliming from the molten polymer. When the opening width of the groove exceeds 39mum, the affection of transfer onto the quickly cooled surface of the sheet becomes remarkable. When the number of intersecting point is under five, an effect to discharge rolled air becomes poor and when the total length of the groove superposed with the straight line exceeds 7mm, transfer onto the surface of the sheet becomes sensitive. When the breathing resistance exceeds 20,000 sec, the discharging effect of the involved air is deteriorated.

Title: Current-carrying control device for glow plug
Inventor: NAKAMURA KOJI
IPC: F02P19/02
Filed: 1992-02-03
Abstract: PURPOSE:To stabilize engine rotating speed after interrupting the continuous current carrying to a glow plug to prevent the deterioration of durability of the blow plug in the fail safe when a key switch is not returned to ON-mode position after starting an engine. CONSTITUTION:When a start signal is not extinguished for a long time, a fail safe timer time T7 passes without canceling the time counting operation in a ST forcedly driven fail safe timer 20. When the time counting of T7 is completed, the timer 20 trails the timer output to a ST forcedly driving part 11 and an interrupted time set timer 16. Thus, the driving part 11 trails the forced drive signal to level 'L', the time 16 starts its operation to start the periodic transmittance of the timer output. At this time, an interrupted control delay timer 15 never starts its time counting operation since the start signal is not extinguished.

Title: Heat exchanger considered to prevent erosion of end of heat transfer tube and to enhance replacing efficiency of tube
Inventor: NAKASO HISASHI
IPC: F28F9/02
Filed: 1992-01-20
Abstract: PURPOSE:To reduce generation of a vortex by allowing an end of a heat transfer tube to protrude in a predetermined length from a tube branch to be mounted, mounting a split inlet tube branch thereat through a trunking tube, a cooling tube for a joint to double the branch, and guiding water to the part by an inlet tube plate. CONSTITUTION:A cooling tube 4' of a condenser 20 so protrudes 4-5cm of suitable length to be mounted at a tube plate 3 as to facilitate a branch tube mounting operation. An inlet tube plate 1 is mounted thereat through a tube plate connecting leg 2 or a trunking tube 5 and a cooling tube 6 for a joint. Thus, a protrusion on a surface of the plate 1 in contact with introduced fluid is eliminated. Further, an inlet is formed in a streamline shape thereby to remove one of causes for generating a vortex. Since a length of a concentric erosion part from the end of the tube is shortened due to the reduction in a vortex generation source, it can be moved to a position of the tube 5 between the plate 3 and the plate 1. Further, since the length of the protrusion of a heat transfer tube 4 is long, a branch tube is facilitated.
