Title: Piston compressor, particularly oil-free piston compressor
Inventor: HANSU BUANAA
IPC: F16C3/12
Filed: 1992-03-12
Abstract: PURPOSE: To provide a piston compressor for considerably reducing assembling and maintaining works. CONSTITUTION: A crank mechanism of a piston compressor comprises individual crank disks 5, which each support on their outer circumference a rolling bearing 6 for the bearing of a connecting rod 4. The crank disks 5 are pressed together to form a package by means of tensioning bolts 7. A crank case 1 is preferably closed off by a case cover 10, the inside of which is formed as a bearing mount for the crank mechanism. Assembly and disassembly of a crank mechanism of this type is particularly simple and efficient and can be undertaken by personnel who are not specially trained. In addition, special grease supply devices provide simple and error free maintenance, and thus greater longevity.

Title: Protective circuit for power converter
Inventor: MITSUNE SHUNSUKE
IPC: H02M7/12
Filed: 1990-03-07
Abstract: PURPOSE:To protect a power converter even when the direction of DC current changes by connecting the output of a second rectifying circuit through a diode to a clamping capacitor for absorbing surge. CONSTITUTION:When the phase u<+> transistor in the upper arm of a converter 1 is abnormal, other phase transistor is not turned ON even if the phase u<+> transistor is turned OFF and thereby the voltage across the phase u<+> transistor increases abruptly. When the voltage exceeds the charging voltage Vc of a clampining capacitor 4, a current bypath circuit is formed as shown by a dashed line and charging of the clamping capacitor takes place. When an overvoltage detecting circuit 10 detects that the voltage Vc exceeds a predetermined level, it makes a judgment of abnormality and all transistors constituting a converter are turned OFF and a load shortcircuiting circuit 7a is operated.

Title: Vane pump
Inventor: TATSUMOTO TOSHIYA
IPC: F04C15/00
Filed: 1995-02-20
Abstract: PURPOSE: To reduce a difference in the elongating force of a vane due to its rotating position so as to enable silent operation and to facilitate machining by forming in one side plate an annular communicating groove of a uniform groove width which communicates all the bottoms of plural vane grooves with one another. CONSTITUTION: This vane pump includes an outer side plate 10 and an inner side plate 4 which are attached to both sides of a rotor 7 and a cam ring 5 to form a pump chamber between the rotor 7 and the cam ring 5. A communicating hole 31 which communicates with a delivery side pump chamber 6b to guide hydraulic pressure to the bottoms of vane grooves 8 is formed in one of the side plates 4, 10. An annular communicating groove 26 of a uniform groove width which communicates all the bottoms of the plural vane grooves 8 with one another is formed in the other side plate. Therefore, noise caused by abrasion or collision between a vane 9 and the inner peripheral surface of the cam ring 5 when the force of the vane 9 to elongate is too large or when timing is off is always prevented from arising. In addition, machining is made very easy.

Abstract: PROBLEM TO BE SOLVED: To eliminate such a case that the digital data reproduced by the traverse of a magnetic head across the recording track and including positional information which corresponds to the memory position to be read out from the memory after that time on the magnetic tape is written into the memory and correct digital data are lost. SOLUTION: A magnetic tape, on which a recording track by a pit stream of digital data including the positional information on the magnetic tape is formed, is made to run in the normal direction at the speed 1/N (N: natural number) times the running speed at the time of recording to extract the positional information on the magnetic tape from the pit stream of the digital data reproduced from the magnetic tape. And, when the memory position of the digital data is written into the memory on which the memory position of the digital data is predetermined in correspondence with the recording position of the digital data on the magnetic tape, it is judged whether the positional information of the reproduced digital data on the magnetic type corresponds to the memory position inside the memory region set in the memory or not.  Otherwise, the digital data, which include the above-described positional information, are prevented from being stored into the memory.

IPC: H05B6/12
Filed: 1995-03-14
Abstract: PURPOSE: To form a magnetic seal part with high yield rate of materials by constituting a doughnut magnetic shield part by overlapping end parts of a plurality of conductive metal plates and arranging the shield part in the circumference of a heater coil. CONSTITUTION: When high frequency current is supplied to a heater coil 15 from a frequency converting apparatus 18, a magnetic field is generated from the coil 15, the magnetic filed crosses a pan made of iron put on a top plate 16, and the pan is heated by the eddy current generated in the pan. Meanwhile, the magnetic field generated in the coil 15 crosses also a closed curved face formed in a magnetic shield part 19 and induction current is generated in the magnetic shield part 19. For that, in the inner side of the magnetic shield part 19, the magnetic field is intensified due to the induction current and on the other hand, in the outer side of the magnetic shield part 19, the magnetic field is weakened, so that the magnetic field in the outside can be suppressed.  Moreover, since the magnetic shield part 19 is installed like a strip in horizontal direction, the part 19 is easy to be inserted in a narrow gap between a holding part 13 and the top plate 16 and is hard to be affected by a pan.
