Title: Method for preventing galvanic corrosion of pipe and its insulating pipe
Inventor: UEDA MASAKATSU
IPC: F16L25/02
Filed: 1991-03-06
Abstract: PURPOSE:To prevent the galvanic corrosion and crevice corrosion from being caused when pipes of different kinds are joined in an oil well, etc. CONSTITUTION:A low-corrosion-resistance pipe 1 and a high-corrosion-resistance pipe 2 are screw-joined directly or through a coupling 3. Insulating films 4 and 5 are formed on the inner and outer faces of the pipe 1 over a length L of >=40mm from the pipe end. Insulating films 6 and 7 are also formed on the coupling 3 over a length L of >=40mm from the pipe end. Insulating films 8 and 9 are formed on the inner and outer faces of the pipe 2 over a length L of >=40mm from the pipe end in the same way as the pipe 1. The thickness of the insulating films is controlled to >=0.4mum and the resistivity in a 5% NaCl soln. at ordinary temp. to >=10<6>OMEGAcm. The similar film is formed, as required, on the screw part for forming a crevice between the joining boundaries A and B of the screw parts on the inner and outer faces.

Title: Air-conditioning system for vehicle
Inventor: SUDOU SHINJI
IPC: B60H1/32
Filed: 1981-03-18
Abstract: PURPOSE:To prevent the blow-off temperature from fluctuating in an air-conditioning system having a compressor adapted to be turned off in response to  the output of the detection of vehicle driving conditions, by recovering the operation of the compressor under the temperature in the vicinity of the outer  surface side of an evaporator. CONSTITUTION:An acceleration detecting switch 15 is turned on when a vehicle is accelerated in the turned-on state of a compressor switch 17, and, therefore, a signal at a point S becomes L-level and is reversed through an reversing circuit 33, and then is delivered to a point CP of a flip-flop 26 through a condenser 34 and a diode 35. Therefore, H pulse is delivered from the flip-flap 26 so that a transistor 23, a relay 21, a switch 22 and a clutch 12 are turned off, thereby the operation of cooling cycle 11 is ceased. Next, when the resistance of a sensor 16 detecting the temperature Tm in the vicinity of an evaporator 3 is decreased due to the temperature rise of the evaporator 3 and a signal at a connecting point to a resistant point 23 reasches a set level, the output of an operational amplifier 25 becomes H level, and the output of the flip-flap is reversed to L level so that the compressor is again turned-on.

Filed: 1981-03-23
Abstract: PURPOSE:To evade a so called undercut phenomenon by setting arrangement of angular pitches of cam followers arranged in the circular form or distances from a common revolution axis to the followers into at least two sorts. CONSTITUTION:Arrangements of angular pitches theta1-theta4 of driven rollers 1a-1d are sorted into two kinds different from each other (theta1=theta3not equal to theta2=theta4).

IPC: G05B19/4103
Filed: 1981-03-20
Abstract: PURPOSE:To facilitate an easy production of an NC tape for a plane grinder, for example, by supplying the shift command of a shaft which is not controlled for the direct shift with the NC distribution pulse along with the shift command of a shaft which receives the direct control in the form of working data. CONSTITUTION:For a plane grinder, for example, a reciprocal shift is given to a table TB in the direction of an axis X and a grindstone wheel GW is shifted toward axes Y and Z to give the plane grinding to a work WK. When the working is carried out for points P0-P3, working data is recorded on an NC tape 101. The present position or the shift extent of the X axis direcion is detected through a pulse coder 107. An interpolarion function unit 104 performs an operation and receives the Z axis direction with the distribution pulse Zp of a pulse distributing pulse. Thus the shift control of Y and Z axes is carried out synchronously with the shift of the X axis to facilitate an easy production of the tape 101.

Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To automatically control suitable negative pressure by exhaust gas according to the operating condition and a load of an internal combustion engine by varying a throttle cross sectional area in the nozzle top end part of a throttle mechanism. SOLUTION: A two steps type air cleaner 2 consists of a pre-cleaner 2a and a double filter 2e having a primary filter 2c and a secondary filter 2d, and dust in sucked air is centrifugally divided and eliminated by the pre-cleaner 2a. Normal air is fed as sucked air 5a into an engine 1 through a suction pipe 5. Negative pressure applied on the nozzle top end part 3c of a nozzle 3a is decided by the flow rate of an exhaust gas flow passage cross sectional area between a throttle mechanism 3b and a nozzle top end part 3c and the flow rate of an exhaust gas 6a. A flow passage cross sectional area is changed and thereby, generating negative pressure of the nozzle top end part 3c is varied, and the flow rate of a flow-in dust 7a from the nozzle 3a is varied.  It is thus possible to improve maintenance property, suppress breakage of a nozzle, and carry out repair and replacement easily if the nozzle is broken.

Abstract: PURPOSE:To enable two conductors to be sufficient from an electric cleaner to a hand switch by arranging a resistor and a bidirectional 3-terminal controlled rectifier in parallel with each other, and suitably connecting the trigger circuit and a switch circuit and the like. CONSTITUTION:When a switch 11 and a contact S1 of a hand switch 5 are closed, a motor-driven blower 2 is rotated, a rated voltage is applied to a motor 13 by the switching operation of a controlled rectifier T1, and an ordinary cleaning can be performed. When the rotating speed of the motor 2 is altered, the contact S2 is closed instead of the contact S1. Thus, the rectifier T1 is closed, and a thyristor 12 is controlled through an amplifier 15. Since the rotation of the blower 2 is gradually increased, in case that the hand switch 5 is contacted at the contact S1 from the contact S2 when the blower 2 rotates at the desired rotating speed, the cleaning can be performed at the desired speed.
