Title: Crown type retainer for rolling bearing
Inventor: HATTORI TOMOYA
IPC: F16C33/38
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a crown type retainer, formed out of solid lubrication material available in the vacuum and under an environmental condition such as high temperature and capable of eliminating a fear of breakage in incorporating balls in respective pockets and a fear of a bearing being locked even if it is broken during running. SOLUTION: The opening dimension L of a pocket 52 is set within the range of 1.00 to 1.01 times the diameter of a ball 4, and the maximum width W1 is set to 0.80 to 0.98 time the distance W2 between the inner sides of the shield plates 6b on both sides of a bearing, by which excessive force is prevented from being applied to a crown type retainer 5 in inserting the ball 4 into a pocket 52. Even if the crown type retainer 5 is broken during running, the shield plate 6b is made to function as a regulating member, thereby preventing broken pieces from moving inside the bearing.

Title: Transistor inverter drive circuit
Inventor: KOSHIHARA MASAHIKO
IPC: H02M3/338
Filed: 1982-04-30
Abstract: PURPOSE:To forcibly reduce a base current when a power source voltage decreases by switching the DC base current necessary to drive a transistor at the zero crossing point of an AC power source voltage. CONSTITUTION:A current does not almost flow through the base of a transistor 19 while the power source voltage is low, and the transistor 19 is interrupted. Thus, the DC voltage which is generated at a condenser 15 allows to supply a current to the bases of transistors 7, 8 through resistors 16, 17, 11, 12, but since the resistor 17 is connected in series, the current is reduced, thereby preventing the excessive overdrive in the period while the power source voltage is low.

IPC: B05B5/053
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To effectively prevent a flying back phenomenon of charged coating particles to an operator from being generated. SOLUTION: Since the value of electric resistance becomes very large, when an operator keeps the apex part of a gun apart from an object to be coated to make the distance not to be an appropriate distance, majority of electric current caused by corona discharge is returned to the earth through the base part of the gun (a grip part). Electric potential of the base part of the gun is elevated by a resistor with a high resistance connected with the midway passage of the earth and the electric current passing to the earth is restricted thereby and in addition, an electric current sensor 36 detects the value of the electric current passing to this earth and transfers it to an electric voltage determining controller 30 and the appropriate value of the electric voltage applied on an electrifying mechanism is calculated so as to decrease the value of this electric current detected to a (preset) definite electric current and the result of the calculation is sent to a booster 32 and in the booster 32, an electric voltage in accordance with this result (a lower electric voltage than the electric voltage at the appropriate distance) is generated and the electric current passing to the earth is restricted.  Therefore, a large electric current caused by corona discharge flows into the base part and the operator and a flying back phenomenon of coating particles can be prevented from being generated.
