Title: Variable displacement swash plate type compressor
Inventor: AN KYUNAN
IPC: F04B27/08
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To prevent eccentric abrasion from generating between a piston body and a cylinder by positioning the bottom end angle of the body between an entrance and the vertex of a shoe pocket adjacent to the body side of the shoe pocket and by arranging a contact prevention means of the piston with the bottom end angle in the swash plate. SOLUTION: A recess 124 is formed in a bridge 122 in a cylinder-shaped piston 110 and a pair of semi-spherical shoes 128 is slidably arranged in a pair of shoe pockets 126 formed in the front/rear of the recess 124. The piston 110 is engaged with a swash plate through the shoes 128 and respective shoe pockets 126 and the piston 110 reciprocates in the cylinder bore by rotation of the swash plate. The inside angle and the vertex Q2 of the piston body are laid on the same line and the inside angle P of the piston is positioned between the entrance Q1 and the vertex Q2 of the shoe pocket. A concave is formed in the swash plate surface opposite to the piston body to prevent the contact of the piston with the bottom end angle.

Title: Network node transceiver of single port with electric power drop protection function
Inventor: FUIRITSUPU RATSUSERU IPUREI
IPC: H03K19/0944
Filed: 1994-12-19
Abstract: PURPOSE: To make a transceiver usable in a prescribed ISDN network by protecting the transceiver from a power drop by controlling the short circuits and removal of the short circuits between the wells and sources of pull-up transistors (TRs) by adding N-type TRs. CONSTITUTION: In the output circuit of the transmitter of a transceiver, the short circuits between the wells and sources of complementarily operating pull-up TRs Q1 and Q2 are controlled by N-type TRs Q6 and Q7 and, when the electric, power drops, the short circuits between the wells and sources of the TRs Q1 and Q2 are removed. Therefore, this transceiver becomes a single- port network node transceiver which is adaptive to Recommendation 1.430 of CCITT, because the wells are insulated from the sources and output terminals 14 and block diode routes to a substrate from the wells and the transceiver is protected from a power drop by preventing the introduction of an induced leakage current from a network 310.

Title: Electrostatic attraction device
Inventor: KAWADA ATSUO
IPC: H01L21/683
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of particles by setting the surface of a part, where at least a sample of an insulation dielectric layer is attracted to a deposition layer formed by a chemical vapor growth deposition method. SOLUTION: Only the part on an attraction surface of an insulation dielectric layer 3 is set to a deposition layer 4 by CVD method, and large part of remaining, insulation dielectric layer 3 is formed by the sintering method or the flame-spraying method. The deposition layer 4 needs to be formed at the part on the attraction surface of at least the insulation dielectric layer 3. As long as the deposition layer 4 is formed at this part and there are no functional problems in an electrostatic attraction device 1, the deposition layer 4 may be formed on the surface of other parts.  In this manner, at least the attraction surface of the insulation dielectric layer 3 is set to the deposition layer by the CVD method, a surface after corrosion and wear when fluorine gas with high corrosive property is used has less recesses and projections, as compared with that which is created by the sintering method and hence becomes uniform, thus reducing the number of occurrence of particles which are generated due to the cutting of a sample (an object to be attracted).
