Title: White organic electroluminescence element
Inventor: MATSUURA MASAHIDE
IPC: H01L51/50
Filed: 1993-11-19
Abstract: PURPOSE:To provide a new white organic electroluminescence element having a specific construction, emitting white luminescence in high luminous efficiency and stability and suitable as a light-emitting element for various displays. CONSTITUTION:The organic electroluminescence element is produced by sandwiching an organic compound containing luminescent layer between a pair of electrodes. At least one of the electrode is (semi)transparent. The luminescent layer has a laminated structure consisting of the 1st luminescent layer containing an organic compound having fluorescence peak wavelength of 380-480nm in solid state (e.g. the compound of formula I) and the 2nd luminescent layer containing an organic compound having a fluorescence peak wavelength of 480-580nm in solid state (preferably 8-hydroxyquinoline, etc.) laminated on the transparent electrode or anode in the order. At least one of the 1st luminescent layer, the 2nd luminescent layer and the other organic compound is incorporated with 0.1-10mol% (based on the organic compound constituting the layer) of an organic compound having fluorescence peak wavelength of 580-680nm in solution state (e.g. dicyanomethylenepyrane of formula II).

Title: Manufacture of eye joint
Inventor: OSHIMA TERUMITSU
IPC: B23K1/18
Filed: 1990-10-25
Abstract: PURPOSE:To reduce inspection mandays by performing a bending process for forming the tip of a pipe member into a bent part, a diameter enlarging process for enlarging the diameter of the bent part to form a diameter-enlarged part, a seat face forming process for forming a seat face at the bottom part and a boring process for forming a vertical hole so as to form a pipe part and an eye part integrally. CONSTITUTION:In a bending process, the tip of a pipe member 1 is bent at a right angle by a bending method using a pipe bender or the like to form a bent part 10. In a diameter enlarging process, the bent part 10 is diameter- enlarged using a press or the like to form a diameter-enlarged part 11. In a seat face forming process, the bottom part of the diameter-enlarged part 11 is machined to be flat to form a seat face 12. In a boring process, a vertical hole 13 piercing the bottom part, provided with the seat face 12, of the diameter- enlarged part 11 is formed by a drill. The vertical hole 13 is formed smaller than the inner diameter of the opening 14 of the diameter-enlarged part 11. An eye part is thus formed. Since the eye part and a pipe part are integrally formed of the pipe member 1, brazing is unrequired, and highly reliable sealing performance can be obtained.

Title: Electrostrictive vibrator control circuit for ultrasonic machining device
Inventor: KATO SEIJI
IPC: B26D7/08
Filed: 1991-10-09
Abstract: PURPOSE:To prevent separation of a detector and the occurrence of an abnormal sound by changing frequency of a reference oscillation circuit by means of a (cds) photocopier while using a light signal outputted according to a phase difference signal of a phase difference comparing circuit, and adjusting resonance frequency slightly in an ultrasonic machining device to vibrate a file, etc., microscopically. CONSTITUTION:For example, in the case of being replaced with a machine tool 6 such as to cause a load change in narrow fluctuation, operation of a changeover switch SW is not necessary, That is, a load current is outputted to a phase light circuit 4 from an electrostrictive vibrator 3 according to the load change smaller than a specific fluctuation width. On the other hand, when a constant reference voltage waveform alpha1 is outputted from a reference oscillation circuit 1, a LED of a (cds) photocoupler of a phase difference comparing circuit 4 emits light according to voltage, and changes resistance of a light receiving section R1, and changes reference frequency. Thereby, a phase difference signal Hr of a voltage value is outputted to the reference oscillation circuit 1, and a resonance condition can be created. When a large load change is caused, the changeover switch SW is switched to the variable resistance R3 side, and coarse adjustment is carried out in the first place by means of a coarse adjustment knob.

Filed: 1988-11-17
Abstract: PURPOSE:To cope with inclinated deflection due to shrinking after molding, with simple composition and retain seal effect for a change with the passage of time, and to prevent contact resistance from being generated at the time of rotation, by making a fitted-on depth between a rotary groove group and a fixed groove group, smaller at a section separated from the rotational center of both surface fans. CONSTITUTION:On three inward ribs 32-34 for forming a rotary groove group 22, the projected lengths are made smaller as they are set more remotely from a rotational center. Besides, three outward ribs 35-37 for forming a fixed groove group 30 are also made smaller on the projected lengths as they are set more remotely from the rotational center. Then, a space (t) between inclination  t to be forecast, and the rib 32 and a fixed groove bottom surface, and a space to between the rib 37 and a rotary groove bottom surface are set as shown by t=to+ t. Then, even if the rotary groove group 22 is inwardly inclined by shrinking after molding, the ribs 32-34 hardly come in contact with the bottom surface of the fixed groove group 30. If the grooves 22, 30 are made shallow in the whole area, seal effect is not enough, but they are made shallower as they are set more remotely from the rotational center, and so the seal effect can be secured.
