Title: Pattern inspection
Inventor: OOBO TAKENORI
IPC: G03F1/84
Filed: 1979-07-11
Abstract: PURPOSE:To evaluate the pattern state of an emulsion mask by detecting the time interval between the peak value of the transmitted light signal at the rise or fall coincides the first threshold and does the second threshold with a vertical scanning at the end rim of the pattern. CONSTITUTION:The section of the light beam is made rectangle 5 in such a manner as to be lengthened vertical to the end line of the pattern 3. To reduce the width of the light beam from the light source, it is limited with the slit after magnified by lens system or the like. The pulses exceeding the output levels L1 and L2 close to the light transmission part and non-light transmission part are separately extracted through two comparators and inputted to an exclusive logic circuit to select the pulses at the height between the two levels which are counted with the pulses from the two levels which are counted with the pulses from the pulse power source through an AND circuit. This provides the time necessary to capture the beginning and the end of the blurring at the end of the pattern 3, thereby allowing the quantitative evalution of the state at the end of the emulsion mask.

Title: Switching circuit
Inventor: KOBAYASHI TADAAKI
IPC: H03K17/60
Filed: 1985-04-24
Abstract: PURPOSE:To attain a high-speed switching action by connecting two diodes in series between an end and an intermediate tap of a transformer with different polarities and then impressing the switching signal to the junction between both diodes via a resistance. CONSTITUTION:The signal supplied to a signal input terminal 1 is amplified by a transistor TR 9 and the induction output emerges at the secondary side of a transformer 12. An end of the secondary side of the transformer 12 is grounded, and the switching signals are impressed through a resistance 15 to both diodes 13 and 14 connected between an end and an intermediate tap of the transformer 12 with polarities opposite to each other. The secondary side impedance of the transformer 12 is changed when the diodes 13 and 14 are turned on and off. The signal having the changed amplitude is delivered to an output terminal 18 through a capacitor 17. Thus it is possible to perform a switching action at an extremely high speed with reception of no effect of a time constant circuit consisting of a bypass capacitor and a resistance.

Title: Ink type dot-printer
Inventor: MORITA YOSHIHISA
IPC: B41J2/305
Filed: 1979-07-11
Abstract: PURPOSE:To obtain a preferable typing quality of an ink type dot-printer by driving an ink jet head provided in the vicinity of a type head in synchronism with type command signals to supply the ink to an ink immersing member, thereby supplying the ink of the necessary amount to the type head. CONSTITUTION:When a piezoelectric element 32 of an ink jet head is driven, ink 33 is injected to be supplied to an ink immersing member 25. Since the member 25 makes contact with a wire 21, the surface of the wire 25 becomes mistened state  with the ink. Then, the ink is moved through a gap between the wire 21 and a  wire guide 22 made of a material such as a hard stone or the like by means of  capillary phenomenon to be adhered to the end of the wire. Seven wires 21 are, for  example, used so that the ink injected from the ink jet head 29 is an amount  corresponding to that of seven wires. The wire 21 selectively enerigzes the electromagnets to impact types on a sheet to type the sheet. The number of piezoelectric  element 32 and nozzle of the ink jet head 29 may respectively suffice at one to cause light weight in an ink dot-printer.

Title: Folding type airtight container and manufacturing method thereof
Inventor: OSADA HIROYASU
IPC: B65D5/74
Filed: 1990-04-02
Abstract: PURPOSE:To make a mutual conversion between a folded form and a box form of a container by a single motion possible regardless of the airtightness of the container by providing linear refraction lines for inward folding or outward folding, which connect the peaks of mountain shaped ruled lines on upper and lower folded-in walls, on right and left both side walls and folded-in walls of an airtight container. CONSTITUTION:On an airtight raw material F, refraction lines 16, 16 by linear ruled lines to connect the peaks of upper and lower mountain shaped ruled lines 15, 15 are formed. When the material is assembled into a box, sealing pieces 5, 5 on right and left both ends are bonded by bending along the refraction lines 16, 16, and then sealing pieces 6, 6 at upper and lower both ends are closed and bonded. Both bondings are by heat-welding by a heat- weldable film 4. When contracted by pressing both ends, the material expands into a box shape as both side walls 11, 11 and folded-in walls 14, 14 extend by the mountain shaped ruled lines 16, 16, and at upper and lower both ends, the folded-in walls 14, 14 are refracted along the mountain shaped ruled lines 16, 16 and become triangle pieces 14a, 14a, and they are folded on the upper and lower surfaces of the box body and bonded. Also, after removing fastening of the triangle pieces 14a, 14a to make them releasable, if front and rear both walls 10, 10 are pressed, both side walls 11, 11 are closed by the refraction lines 16, 16, and the triangle pieces 14a, 14a are once released and are closed by the refraction lines 16, 16, and therefore, a flat folded form is given.

Filed: 1978-07-19
Abstract: PURPOSE: To produce long-length optical fiber bundles with good efficiency with a small device by combining plural guide rods for letting optical fibers make a round in zigzag form, aligning jigs and laminating mold frames.  
     CONSTITUTION: Optical fibers are looped several times zigzag to the plural reeling guide rods 1 erected to a reeling base board 13 to form a single layer fiber ribbon 3' (Fig. A). The optical fibers are then arrayed in a single layer with the slant fiber rest 2' of the fiber aligning jig 2 disposed on the way of the loop and the arrayed portion 3" is solidified in foil form by using epoxy resins or the like (Fig. B). This operation is repeated while moving in the axial direction of the rods 1 to form plural (e.g., 4 sets) single layer fiber ribbons 3' (Fig. A). Next, the rods 1 shown by the alternate long and two short dashes line are removed and the group of the ribbons 3' is loosened to drop the arrayed portions 3" of the ribbons 3' into a laminating mold frame 4. These are then laminated and are solidified by epoxy resins (Fig. C). At this portions, the optical fibers are cut, whereby the long-length optical fiber bundle is obtained.

Title: Clamp pulse generating circuit
Inventor: WATABE HIROYUKI
IPC: H04N5/18
Filed: 1989-04-06
Abstract: PURPOSE:To prevent a clamp pulse period from being overlapped onto a transmission period of a synchronizing signal and a video signal by specifying a timing for forming the front ridge of a clamp pulse based on the trailing ridge of a synchronizing signal and forming a timing for forming the trailing ridge based on the front ridge of the synchronizing signal respectively. CONSTITUTION:The timing for forming the front ridge of a clamp pulse CP outputted from an AND gate 3 and applied to a clamp input terminal of a clamp circuit 4 is specified based on the trailing ridge of a synchronizing signal Sync and the timing for forming the trailing ridge is specified by a delay time of a monostable multivibrator 2 triggered based on the front ridge of the synchronizing signal Sync. Since the delay time of the monostable multivibrator 2 is constant so long as the CR time constant is unchanged, the timing for forming the trailing ridge of the clamp pulse CP is specified based on the front ridge of the synchronizing signal. Thus, invasion of the clamp pulse into the effective pattern and the horizontal synchronizing signal is avoided.
