Patent JP-H04203382-A (JP)
Title: Oil cooled type screw compressor
Inventor: MAEDA JUNJI
IPC: F04C18/16
Filed: 1990-11-30
Abstract: PURPOSE:To reduce a high frequency noise and vibration of a rotor by a method wherein a discharged oil recovering pipe for a bearing at a discharging side is separated at a female rotor and a male rotor, a solenoid valve and an orifice for metering an amount of recovered oil are arranged in parallel at the recovery pipe at the female rotor side and they are connected to a suction port. CONSTITUTION:Discharged oil at a female rotor passes through a recovery pipe 16 under a differential pressure between an inside part of a D cover 12 and an inside part of a suction port 17 and the discharged oil is recovered into the suction port 17. A solenoid valve 14 and an orifice 15 for adjusting an amount of recovered oil are arranged in parallel to the recovering pipe 16. Under a full load operation, the solenoid valve 14 is opened and the discharged oil at the female rotor is recovered from both the solenoid valve 14 and the orifice 15. Under an unloading operation, the solenoid valve 14 is closed in response to an electrical signal of a pressure switch 27. Due to this fact, the discharged oil at the female rotor is recovered into a suction port 17 only through the orifice 15 and thus an amount of recovered oil can be adjusted to be low in its volume.

Title: Manufacture of camshaft
Inventor: NOMURA SEIJI
IPC: B23K1/00
Filed: 1989-12-18
Abstract: PURPOSE:To prevent any fretting abrasion from occurring between the inner circumferential surface of a cam member and the outer circumferential surface of a shaft member by carburizing a camshaft blank after interposing a brazing material between both these surfaces and fitting them together. CONSTITUTION:A cam member 1, having a hollow part 1a piercing through in the axial direction is fitted in an outer circumference of a pipe-make shaft member 2 after interposing a brazing material 3 between an inner circumferential surface of the cam member 1 and an outer circumferential surface of the shaft member 2. Then, both side ends 1c in the axial direction of the camshaft 1 and the shaft member 2 are welded together and thereby a camshaft blank 5 is secured, and then this blank is carburized. With this cementation, the brazing material 3 is melted by heat at time of carburization and diffused in the axial direction, thus the inner circumferential surface of the cam member 1 and the outer circumferential surface of the shaft member 2 are joined together by means of brazing. Therefore any fretting abrasion between the inner circumferential surface of the cam member 1 and the outer circumferential surface of the shaft member 2 is preventable.

Title: Thyristor converter
Inventor: HORIUCHI SUSUMU
IPC: H02M1/00
Filed: 1990-11-29
Abstract: PURPOSE:To prevent destruction of a VBO-free optical thyristor by continuing an optical gate signal given to the VBO-free optical thyristor during the period till its current interruption, generated by a vibratory current, disappears. CONSTITUTION:When VBO-free optical thyristors 6-1 to 6-N are VBO-ignited, a VBO firing signal (e) becomes 1 by actuating a VBO firing detecting circuit 18. This signal is input to a monomulti-vibrator circuit 16, which then produces a pulse E having duration long enough to suppress a high frequency vibratory current, generated by VBO firing, below a main circuit current. By inputting this pulse E to an OR circuit 17, a gate signal (f) of length T1 is generated to give an optical gate pulse to the VBO-free optical thyristors 6-1 to 6-N. In this way, all the VBO-free optical thyristors 6-1 to 6-N can be ignited immediately when forward voltage is applied.

Title: Production of thin-film magnetic head
Inventor: OTSUKA KOJI
IPC: G11B5/31
Filed: 1989-12-22
Abstract: PURPOSE:To allow the connection of plural conductor coils without generating the abnormality of the resistance value in the connected parts thereof by forming holes on an insulating layer until the conductor coils are exposed and selectively growing the conductors in the hole parts up to the front surface of the insulating layer, thereby connecting the conductor coils to each other. CONSTITUTION:The interlayer insulating layer 6 is formed on the insulating layer 4 formed with the conductor coils 5 and is etched to form the holes 61 until the conductor coils are exposed. The conductors 65 are then selectively grown in the holes 61 until the conductors grow approximately flush with the front surface of the interlayer insulating layer 6. The conductor layer consisting of two layers of high-melting metal layers 71, 73 and copper 72 are thereafter formed on the interlayer insulating layer 6 to form the conductor coils 7 and wiring layers. The generation of the step cutting and cutting-in in the parts where the plural conductor coils 7 are connected is obviated in this way and the increase in the resistance by the selectively grown conductors 65 is negligible and, therefore, the conductor coils 7 of the low resistance value are formed with good reproducibility.
