Title: Gate drive of power mosfet switch
Inventor: MAAKU ERIOTSUTO JIYAKOBUZU
IPC: H03K17/687
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility of allowing a noise voltage pulse on a gate driving circuit to unnecessarily turn on a MOSFET switch by adding a nonlinear break down diode and the parallel circuit of a capacitor to a gate driving circuit. SOLUTION: In order to improve the gate drive circuit, the nonlinear break down diode (constant voltage diode) CR4 and the parallel combination of a capacitor C1 are included. By the adding of this parallel combination, Q1 is supposed to be N channel power MOSFET and a negative DC voltage is added to between the gate and source of a switch to increase a protecting degree to the unexpected contact turn on of power MOSFET. In this case, a noise spike should amount to a gate-source threshold voltage before MOSFET is commutated to on by exceeding the quantity of negative bias. The introduced negative bias is provided with a protecting degree to prevent the occurrence of an attempt only for maintaining a gate to be zero voltage.

Title: Cam plate type compressor
Inventor: KAWAI KATSUNORI
IPC: F04B39/02
Filed: 1989-08-09
Abstract: PURPOSE:To continually secure an amount of oil necessary for lubrication by forming a suction port on a cylinder block for return refrigerant gas to a cam plate chamber, and an oil separation part in between the cam plate chamber and a compression chamber, and returning separated oil to the cam plate chamber. CONSTITUTION:The refrigerant gas discharged into a separation chamber 30 through a passage 32a from a cam plate chamber 8 changes its direction of flow on hitting a covering body 31. Misty oil O contained in the refrigerant gas then adheres to the covering body 31, and drips down over a guide wall 34 to the bottom of the separation chamber 30 and is accumulated therein. Since the oil O is separated soon after the refrigerant gas is discharged from the cam plate chamber 8 in this case, its temperature has not gone up so much that no deterioration is caused in its lubrication characteristic. The accumulated oil O is drip-supplied to the cam plate chamber 8 through a return passage 33 for the lubrication of a piston 13, shoes 14, a thrust bearing 15, etc. The lubrication characteristic is thus retained satisfactorily to prevent seizure of respective sliding parts.

Filed: 1991-08-19
Abstract: PURPOSE:To obtain a magnetic recording medium provided with a plasma- polymerized protective film which is improved in wet durability on a magnetic recording layer by fluorinating the surface of the plasma-polymerized protective film. CONSTITUTION:In this magnetic recording medium provided with a protective film 14 composed of a plasma-polymerized film using phenyl hydrocarbon as a monomer on the surface of a magnetic recording layer 3, the surface of the film 14 is fluorinated by exposing the surface to the plasma of a CF4 gas or a CF4 gas added with a small amount of an O2 gas so that the hydrogen atoms contained in the surface section of the film 14 can be replaced with fluorine atoms. Since the fluorinated surface of the film 14 is highly fluorinated and has extremely low surface energy, the surface has a low coefficient of friction and high wet characteristics. Therefore, a magnetic recording medium provided with a protective film which is improved in the wet durability together with the durability can be obtained.
