Title: Control unit for hydraulic motor
Inventor: KOSAKA MASATO
IPC: F15B11/02
Filed: 1991-02-19
Abstract: PURPOSE:To prevent a shock by providing a swash plate control cylinder in opposition to the swash plate of a hydraulic motor in a control unit of hydraulic motor in a construction machine, so that the connecting to a pump or tank is switched in accordance with large or small capacity control, and a relief is also switched to the tank or pump side interlockingly with this. CONSTITUTION:When a port 4 is connected to a pump, a hydraulic pump 1 is rotated at high speed, and a cylinder 9 is connected to a tank side through a pilot circuit 28 to make the capacity of the set pressure of a relief valve 8 small. Thus, even if the torque is increased, a shock can be controlled, at the time of reversed driving, a port 5 is connected to the pump 1 side, a cylinder 9a with spring is connected to the tank side, and the set pressure of a relief valve 8a becomes small. When the normal drive is conducted by a switching valve 21, a high pressure is introduced to a swash plate cylinder 18a, and a swash plate 13 is pressed in a direction Y and rotated. Thus, a small capacity control position can be set.

Title: Optical scanning device
Inventor: INOUE NOZOMI
IPC: G02B26/10
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to use a reflecting mirror which is manufactured by an inexpensive manufacturing method as a reflecting mirror for returning an optical path that a transmission optical system uses by matching a direction of excellent flatness of a reflecting mirror with a horizontal scanning direction. SOLUTION: Mirrors which have reflecting films vapor-deposited on the surface of float glass are used as reflecting mirrors 51 and 52 placed in the transmission optical device. The continuously produced float glass is different in flatness between the progress direction of the manufacturing process and its orthogonal direction, so the direction of excellent flatness is matched with the horizontal scanning direction to make it possible to use the inexpensive reflecting mirror. To maintain the flatness of glass, specific thickness is needed for both polished glass and float glass, and glass of, for example, 5mm in thickness is used for the reflecting mirrors 51 and 52 to obtain sufficient flatness.  Further, even when a reflecting mirror is interposed in a beam shaping optical system as well as the transmission optical system, inexpensive float glass is made usable by matching the direction of excellent flatness with the horizontal scanning direction in exactly the same way.

Title: Method of valve shutoff
Inventor: TAKAHASHI KAZUO
IPC: F28F11/00
Filed: 1983-03-18
Abstract: PURPOSE:To maintain a sound sealing performance with a long service life by forming an emergency shutoff valve for a steam generator, etc. of a high speed furnace with a shape memory alloy having a memory of a shape of a diameter larger than the shutoff valve which restores the memory shape by being heated after the insertion. CONSTITUTION:In order to shut off a pipe hole 12, a connector 15 in the form of a flanged sleeve is first inserted into the pipe hole 12, and then a plug 10 is inserted into the connector 15. thereafter, upon inserting the connector 15 and the plug 10 until the flange contacts the end of the pipe hole 12, a heater 14 is electrified to heat the plug to a shape restoring temperature. As the plug restores its memory shape by being heated, the pipe hole 12 can be plugged. As a compression force acts upon the connector between a heat transmission pipe 20 and the plug 10 by the plug's restoring its memory shape, the plug 10 and the pipe hole 12 of the heat transmission pipe 20 are tightly held. From this moment on, since the piping of the high speed furnace stays at a high temperature because of a steam temperature, the plugging condition can be maintained safely.

IPC: B60L11/18
Filed: 1990-02-27
Abstract: PURPOSE:To sustain magnetic levitation even during charging operation by connecting two electric contacts, arranged in a carrier station, with a battery charging connector arranged on the outer face of a magnetic levitation carrier and a connector connected with a levitation magnet. CONSTITUTION:When a carrier is running, a relay 25 is demagnetized to open contacts 28a-28d and to close contact 26, 27. Consequently, batteries 12, 13 are connected in series and the voltage across the batteries is fed through a connector 24 to a levitation magnet thus energizing the levitation magnet. When the carrier stops at a station, an arm is extended to bring contacts 17, 18 into contact with connectors 14, 15. At first, a switch 20 is turned ON to connect a power supply 22 with the connector 15 thus energizing the magnet through the output connector 24. Upon subsequent turn ON of a switch 19 to connect a charger 21, the relay 25 is energized to open the contacts 26, 27 and to close the contacts 28a-28d thus connecting the batteries 12, 13 in parallel and subjecting to charging operation 21. consequently, the carrier is sustained in levitating state even when it is not running and an object to be carried is protected against damage due to lifting/lowering of the carrier.
