Title: Lubricating oil feed device for vacuum pump for vacuum car
Inventor: NAKANO TSUGUTAROU
IPC: E03F7/10
Filed: 1989-05-18
Abstract: PURPOSE:To prevent deterioration of lubricating oil through prevention of entrance of water to an oil chamber by a method wherein a lubricating oil chamber is partitioned from an air chamber to store exhaust air by means of a partition plate, and a communicating pipe extended in the air chamber and communicated to the oil chamber is installed to the partition plate. CONSTITUTION:An oil chamber 31 to store lubricating oil, an air chamber 40 to store exhaust air through an exhaust chamber route, and a partition plate 50 to partition the oil chamber 31 from the air chamber 40 are provided. A U-shaped communicating pipe 51 is erected from the partition plate 50, and the air chamber 40 and the oil chamber 31 are intercommunicated therethrough. When, during suction and drainage of water to be sucked and drained, exhaust air enters the air chamber 40 through an inlet part 41, the exhaust air is brought into contact with a cylinder body 43, and rises within the cylinder body 43 and flows to an outlet part 42. A part of exhaust air pushes an oil level in the oil chamber 31 through the pipe 51 and forcibly feeds lubricating oil. However, the flow of condensed water produced through compression and cooling of the exhaust air is stopped by the partition plate 50 to prevent the occurrence of the situation in which water is mixed in lubricating oil.

IPC: B65G47/68
Filed: 1988-05-24
Abstract: PURPOSE:To shorten a feed line by weighing the wt. of a material to be treated and subsequently feeding out the material to be treated to the next stage process and a recovery side in such a state that the weighing posture of the material to be treated is held. CONSTITUTION:When the material 2 to be treated from a work station 1' is transferred to a wt. measuring conveyor 7 by a manipulator 1'', the wt. of the material 2 to be treated is measured after a predetermined time and the detection signal thereof is inputted to a computer to judge whether said material 2 is an acceptable product having a set wt. In the judgement of a normal wt. product, the manipulator 1'' transfers the normal wt. product 2' to the feed conveyor 8 to the next stage process from the conveyor 7 to feed the same to the next stage process. When the material 2 to be treated is not within a proper wt. range, said material 2 is judged to be an abnormal wt. product 2'' and the manipulator 1'' is not operated and the conveyor 7 is revolved to the feed conveyor 9 toward a recovery side and the abnormal wt. product 2'' is transferred to the conveyor 9 to the recovery side as it is to be fed to the recovery side.

Title: Synchronous converter for video signal
Inventor: HIRAKAWA HIDEJI
IPC: H04N5/073
Filed: 1979-09-28
Abstract: PURPOSE:To prevent a video signal from lagging a sound signal by comparing an input video signal to the synchronizing signal component of a reference video signal and by exercising readout control over a memory part according to the phase difference. CONSTITUTION:Synchronizing signal component Is extracted from input video signal VIP and synchronizing signal component Ss extracted from a reference video signal are both supplied to phase comparison part 14, which compares the phase difference between both the synchronizing signal components to a reference phase. This comparison output is supplied to readout control part 13. Since the phase difference of phase comparator 14 is greater than a prescribed reference phase difference when input video signal VIP is not of its own, readout control part 13 is controlled with the output of phase comparison part 14 so that a normal readout timing signal will be outputted. When the input video signal is of its own, it is less than the prescribed reference phase difference, so readout control part 13 is so controlled that the output video signal will not lag much. Therefore, the delay of the video signal behind the sound signal can be suppressed as much as possible.

Title: Driving device for driving shaft of railway rolling stock
Inventor: YURUGEN KUUROU
IPC: B61C9/52
Filed: 1981-08-10
Abstract: In a propulsion unit for the driven axles of an electrically-powered rail vehicle, the torque of an electric propulsion motor is transmitted to the respective driven axle by way of a torque transmitting mechanism including gears and couplings. A common housing in the form of a hollow beam is used to enclose the propulsion motor, a bearing system, and a transmission. Cut-outs are provided in the sides of the housing to allow space for the driven axles. In order to increase the flexural and torsional stiffness of the propulsion unit, the hollow beam includes an annular end surface through which the propulsion motor and torque transmitting apparatus are inserted. The hollow beam not only forms a common housing or the propulsion components, but is a very stiff support element that reduces vibration and improves the running behavior of the propulsion unit.

Title: Manufacture of resinoid grinding wheel
Inventor: AIZAWA TERUKI
IPC: B24D3/28
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent poor appearance such as swelling from generating by molding mixture of thermosetting resin containing benzoxazine compound, liquid epoxy resin, and abrasive grains into a fixed shape, and thereafter thermosetting under no addition of pressure. SOLUTION: Mixture of thermosetting resin containing benzoxazine compound, liquid epoxy resin, and abrasive grains is molded. Thereafter it is heated and hardened under no application of pressure. The content of this thermosetting resin is over 10-60vol.%, and the territory of high resin ratio of over 20vol.% is desired. Because the resin series do not generate volatile byproduct at hardening, poor appearance such as swelling is not generated even at thermosetting in a no pressure state, and a uniform and precise molding hardly changing the shape before and after the molding can be manufactured.

Title: Auto zero device of wattmeter
Inventor: KUDO MAKOTO
IPC: G01R21/133
Filed: 1993-04-28
Abstract: PURPOSE:To obtain an auto zero device of a wide-band wattmeter which is so designed as to cancel an offset voltage generated in a multiplier, without necessitating a clock. CONSTITUTION:A multiplier 1 for multiplying a voltage and a current of a line is put in a state of a current input being 'broken' and an offset voltage thereof is converted digitally and detected by a controller 6. Then, data are given properly from the controller 6 to a D/A converter 7 and an analog output voltage of the converter is fed back negatively to the multiplier so as to cancel the offset voltage. The controller holds the data which it gives to the D/A converter 7 when the offset voltage becomes zero, and applies the negative feedback voltage to the multiplier constantly. The detection of the offset voltage, updating of the data given to the D/A converter 7, etc., are conducted periodically. Accordingly, a clock for high-speed switching is dispensed with.

Title: Magnetic head and its production
Inventor: TOMA TERUO
IPC: G11B5/23
Filed: 1988-05-23
Abstract: PURPOSE:To prevent formation of a nonmagnetic layer to improve the frequency characteristic of the recorded and reproduced output of a magnetic head by interposing a mixing layer consisting of the core material of a magnetic core, the metallic magnetic material of a metallic magnetic film, and oxygen between the metallic magnetic film and a magnetic gap forming surface of the magnetic core. CONSTITUTION:At the time of forming a metallic magnetic film 2 stuck to the forming surface of a magnetic gap 3 of a magnetic core 1, the mixing layer consisting of the core material of the magnetic core 1, the metallic magnetic material of the metallic magnetic film, and oxygen is interposed between the metallic magnetic film 2 and the forming surface of the magnetic gap 3 of the magnetic core 1. Therefore, the substrate surface of the magnetic core 1 consisting of an Mn-Zn ferrite or the like is sputtered and cleaned by an oxygen ion beam, and the metallic magnetic film 2 consisting of a 'Sendust(R)' or the like is laminated with a prescribed thickness. Consequently, the diffusion quantity of aluminum into the ferrite is reduced to eliminate the quick change of the composition in the junction boundary surface between the Mn-Zn ferrite 1 and the sendust 2. Thus, a nonmagnetic layer is not formed, and the frequency characteristic of the recorded and reproduced output is improved.
