Title: Hermetic type compressor
Inventor: KISHINO MASAHIRO
IPC: F04C29/12
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a hermetic type compressor which reduces outflow of refrigerating machine oil to refrigeration cycle, supplies sufficient lubricating oil to each sliding part of a compression element, causes no seizure with high reliability, sufficiently performs oil sealing at a compression part with proper oil supply, and keeps high performance. SOLUTION: A compressor has a first space 16 into which mixture of refrigerant and refrigerating machine oil is flowed from a compression element 2 through a discharge port 10, and a second space 17 having a discharge pipe for supplying the refrigerant to a refrigeration cycle. A flow passage 32 composed of a plurality of communication passages 31 and rectifying duct having plural flow passages corresponding to the communication passages is arranged between the first and second spaces. A chamber structure is arranged on the rectifying duct 32 for sufficiently lowering the velocity of the refrigerant so as to prevent remixing and atomization of the refrigerating machine oil and refrigerant which are substantially separated from each other in the first space.  It is thus possible to reduce outflow of the refrigerating machine oil to the refrigeration cycle, and obtain high reliability and performance.

Title: Laser apparatus
Inventor: KUZUMOTO MASAKI
IPC: H01S3/0975
Filed: 1993-01-21
Abstract: PURPOSE:To obtain a laser apparatus, which can perform highly efficient laser excitation readily in an arbitrary frequency region. CONSTITUTION:Discharging is generated in the slant direction in the rectangular cross section of a discharging space 4 for lazer excitation having the rectangular cross section whose ratio between the long side the short side is 3 or more in this constitution. The discharging is generated in the slant direction with respect to the direction of an optical axis, which is orthogonally intersecting the rectangular cross section within the discharging space 4 in this constitution. Thus, the highly efficient laser oscillator can be realized with a power supply having the arbitrary frequency. Therefore, the laser apparatus, which can be readily used, is obtained at the low cost.

Title: Torque fluctuation reducing device for reciprocating machine driving device
Inventor: FUJII TADASHI
IPC: F16H35/00
Filed: 1981-02-23
Abstract: PURPOSE:To reduce torque fluctuation by juxtaposing an eccentric mechanism on the same driving shaft in the direction shifted at an angle of 90 deg. against the eccentric direction of the eccentric mechanism or on an another shaft connected to said driving shaft with a transmission gear ratio of 1 and by connecting a rocking body to said juxtaposed eccentric mechanism. CONSTITUTION:Rocking motion of a rocking frame causes additional mass 18 to rock around S point by a lever 17 driven by a concentric shaft 1 with a phase angle of delay of 90 deg. compared with said rocking. As the result of this, torque of resistance (load torque) produced by the rocking of the additional mass 18 is yielded along the shaft 1. However, when this torque of resistance is compared with torque of resistance in the case of only a rocking frame 2, a secondary component of torque of resistance of the whole device decreases since the sign of the secondary component is inverted.

Title: Image forming apparatus
Inventor: HIGUCHI KAZUHIKO
IPC: B42D15/10
Filed: 1990-02-06
Abstract: PURPOSE:To prevent forgery and alteration wherein a main image is substituted because the regional separation from a medium becomes difficult by changing the density at the peripheral part of the main image in a variable density image obtained by an input means by an image processing means. CONSTITUTION:A coefficient group having coefficient distribution as the density distribution at an arbitrary lateral position is prepared. That is, the coefficient group is set so as to be equal to or larger than the number of the longitudinal and lateral pixels of an image 31 and constituted so that the central region is set to '1' the left and right outer peripheries are set to '0' and the intermediate thereof smoothly changes from '1' to '0' toward the outer peripheries. The density difference between the image 31 and the outside thereof is large and the separation and visual confirmation of the boundary thereof is easy. By multiplying the image corresponding to each pixel position and a coefficient, a processed image is obtained. In the processed image, the density difference between the periphery of the image 31 before processing and the left and right outsides thereof is eliminated, that is, the left and right outer peripheries 36 of the image 31 before processing are removed. When outer peripheral part of the image, that is, the boundary of the inside and outside of the image can not be visually confirmed, forgery and alteration become difficult.

IPC: H01L33/00
Filed: 1989-02-03
Abstract: PURPOSE:To shorten the breaking time of a current flowing to a light emitting element by rapidly neutralizing charge remaining at the light emitting element by a current supplied from a current supplying circuit at the time of extinction of the light emitting element. CONSTITUTION:A switching circuit 6 inputs binary signals of the same phase and reverse phase, and varies a current flowing to a LED 7 by 100% to intermittently interrupt the current. A pulse generator 8 inputs a binary signal of reverse phase output from a comparator 5, generates a pulse at the time of varying of the binary signal of the reverse phase to output it. A current source circuit 9 inputs the pulse, selects only a pulse having a predetermined polarity, and supplies a current responsive to the selected pulse to the cathode of the LED 7. The generator 8 and the current source 9 constitute a current supplying circuit. Thus, charge remaining at the LED 7 at the time of distinction of the LED 7 is rapidly neutralized to shorten the breaking time of the current flowing to the LED 7.
