Title: Diesel engine lubrication device
Inventor: HIROKAWA NOBORU
IPC: F01M1/16
Filed: 1983-08-23
Abstract: PURPOSE:To lubricate necessary quantity in case of necessity regardless of engine rotation by inputting and operating a signal from an operational condition detector and having a lubricating valve nozzle eject adequate quantity of lubricating oil intermittently only while said nozzle is positioned between piston rings at upper and lower ends of a crown. CONSTITUTION:Aiming at a timing when the nozzle 35 of an oiling valve 24 is positioned between the uppermost piston ring 3' and the lowermost piston ring 3'' at every interval of, for example, about ten seconds after an electric signal of axial angle for A crank is inputted, a pulse signal is inputted to a lubricator 25 so as to have one nozzle 35 eject lubricating oil as much as, for example, adequate quantity of 0.05cc and only during said timing, for example, 0.05sec. When the pulse signal is inputted from an operation command transmitter 31 through a conductor 34 to solenoid 21' of a solenoid valve 21, the solenoid 21' is excited only for that period, and changes over the position of the solenoid valve 21 to the left, then pilot oil sent from a pilot pump 38 through a working oil tank 27 is sent into a pilot board 36 only while the pulse signal continues. Thus, the necessary amount of lubrication can be certainly performed when it is necessary.

Title: Axial piston device
Inventor: NAKATSUJI JUN
IPC: F04B1/20
Filed: 1989-06-15
Abstract: PURPOSE:To damp the transmission of the vibration of a piston to exterior and substantially reduce noise by movably providing a plate 50, with which a shoe is slidably brought into contact, to a swash plate and arranging oil chambers to which pressured oil is introduced between the plate and swash plate. CONSTITUTION:A plate 50 with which a shoe is slidably brought into contact is movably provided to a swash plate 38. Between the the plate 50 and swash plate 38 oil chambers 41, 43, and 44 are arranged to be introduced pressured oil. These oil chambers comprises a rough ring-like groove 41 which is formed to the surface of the swash plate 38 and corresponds to the locus of the shoe 11. The groove 41 has the portion 43 of broad area corresponding to a high pressure port 19. The area of the portion 44 corresponding to a low pressure port 20 is narrower than that of the portion 43. Thus, the vibration of a piston can not be transmitted to the swash plate directly, and the noise discharged to exterior is substantially reduced. In addition, since the force pushing against the plate is balanced, the plate can always be maintained at a normal attitude.

IPC: G01M11/02
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To derive a time lag with high reproducibility by determining the time lag of an optical pulse propagated on other optical fiber with reference to the time of an optical pulse propagating on an arbitrary optical fiber and arriving at a light receiving unit. SOLUTION: An optical pulse from a common light source 15 is divided through a photocoupler 3a into two which pass through a connector 16 and enter into a multimode optical fiber of the arbitrary reference line and a measuring line of a four core optical fiber tape 17. Optical pulses propagating on two optical fibers are coupled through a photocoupler 3b and observed through a light receiving unit 9. With reference to the time of the optical pulse propagating on the arbitrary reference line and arriving at the light receiving unit 9, time lag of the optical pulse propagating on the measuring line behind the reference arriving time is determined as a skew. The measurement is carried out for the measuring line of other optical fiber and the skew is determined with respect to the reference line. According to the method, skew can be derived with high reprodicibility.

Title: Multiple shaft screw fastener
Inventor: ADACHI MASATOMO
IPC: B23P19/06
Filed: 1981-09-26
Abstract: PURPOSE:To prevent final torque of each shaft from dispersion and make it coincide with a desired value by providing fitting-up torque to each shaft which is fastened simultaneously to a desired fastening torque after the fitting-up torque  is reached. CONSTITUTION:In a double shaft screw fastener, when shaft torque of one driver bit 12a reaches fitting-up torque set by a first torque setting means 20a earlier than the other driver bit 12b, a drive motor 13a for the driver bit 12a is stopped. Thereafter, when the shaft torque of the other driver bit 12b reaches the fitting- up torque, a signal of fitting-up completion is generated to drive the motor 13a again. Thus, since the respective driver bits 12a, 12b start the fastening as soon as the fitting-up of all shafts is completed, they reach a desired fastening torque set by second torque setting means 21a, 21b approximately at the same time and motors 13a, 13b for the respective shafts are stopped by the signals of completed fastening generated from second comarators 19a, 19b.
