Title: Positioning device for linear motor transporting apparatus
Inventor: HIRAI ATSUO
IPC: G05D3/10
Filed: 1987-11-02
Abstract: PURPOSE:To enable a truck to be exactly positioned at a fixed position even if the speed and weight of the truck are changed, by setting a buffer which can be transferred to a position for stopping the truck and a position for getting rid of the truck when the truck passes. CONSTITUTION:When a truck 3 is applied for a linear motor for a stop station, then by a thrust in the counter direction of the linear motor, the truck 3 is decelerated. When it is detected that the truck is run at a low speed, then the linear motor is switched to a weak thrust in the positive direction. When the projection 4 of the truck 3 is struck against a buffer 13, then the truck 3 stops at the final end of the buffer 13 for balancing the weak thrust of the linear motor with the working force of the buffer 13. In this case, the buffer 13 of a station where the truck 3 is started or passed is switched toward a retreating position. As a result, the truck can be exactly stopped at high precision.

Title: Method for cleaning filter of copper electrolyte filter device
Inventor: MARUYAMA TSUNEO
IPC: C25C1/12
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To dispense with the use of a noxious hydrofluoric acid and thereby enhance the safety of a cleaning operation by cleaning a precoat-type filter which is clogged by a scale or a slime resulting from copper electrolysis, using an ultrasonic wave, when a suspended matter contained in an electrolyte is filtered with the help of a silica precoating agent. SOLUTION: A filter frame with a stainless steel woven metal wire is attached to the internal forward/backward faces of a filter device 3. A silica precoating agent layer is formed on each of the outside faces of the stainless steel woven metal wire using the self-circulation route of the filter device 3 and thus a precoat-type filter 4 is manufactured. When the precoat-type filter 4 which is useless due to clogging is cleaned, no noxious hydrofluoric acid is used. Consequently, a clog-causing matter is shaken to be loosened by suspending a plurality of ultrasonic oscillators 5 instead, in the water between the wall of a water tank and a soaked filter body. Alternatively, the ultrasonic oscillator 5 is attached to the filter device 3 to apply an ultrasonic oscillation to the filter body to loosen the clog-causing matter apart.

Filed: 1988-11-07
Abstract: PURPOSE: To obtain as large collimation line deviation as possible in a specific adjustment stroke of an inversion system by arranging an operation point for inversion system adjustment a distance behind an objective image plane and making the distance meet specific conditions at this time. CONSTITUTION: The turnable support part of an auxiliary lens barrel 4 has no friction because of a monolithic spring joint 4a, which elastically deform when the auxiliary lens barrel turns, at the end part of the auxiliary lens barrel 4. A cross line is built in an ocular image plane 2a and the operation point for the adjustment of the inversion system 3 is a value S, defined by an expression I, behind the objective lens plane 1a. In the expression, L is the distance between the objective lens image plane 1a and ocular lens image plane 2a, and β is the power of the inversion system. In this case, the collimation line deviation is irrelevant to the lateral deviation of the center of the turning. Consequently, the adjustment of the collimation line can greatly be expanded with specific size of the collimation telescope.

Title: Snow melting device for air tent
Inventor: KITANO MANABU
IPC: E04H15/20
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To improve energy efficiency at the time of snow melting. SOLUTION: A hot air from a hot air supplying device is introduced into an air chamber 14a of an air tent through an air duct 22a, an electric damper 23 and an air inlet 20a, passes through the air chamber 14a and warms a snow 42 accumulated on a film 4a. As a result, the snow 42 is melted and removed from the film 4a. A controlling device sets an opening degree of the electric damper 23 based on a signal from an anemoscope mounted close to the air tent. That is, when the wind direction is as shown in an arrow A, the opening degree of the electric damper 23 at the leeward is set larger, while the opening degree of the electric damper 23 at windward is set smaller. Thus, even if more snow accumulates at the leeward, more hot air is supplied to the air chamber 14a at the leeward, and snow melting progresses uniformly on the whole.  And waste of more hot air at the windward regardless of completion of snow removal at the windward can be solved.

Title: Cable cooling device
Inventor: KATO MASAHIRO
IPC: H01B13/14
Filed: 1993-11-09
Abstract: PURPOSE:To protect the surface of a cable, prevent leakage of gas in between a packing and the cable, and improve quality of a cross-liked polyethylene cable. CONSTITUTION:When a cable 1 passes a packing 5 and proceeds into a cooling pipe 3, a lubricating liquid 7 is supplied from the upper part of the packing 5. The lubricating liquid 7 creeps on the upper face of the packing 5 and sticks to the outer peripheral face of the cable 1 so as to form a thin coat 12. The coat 12 works as a lubricant for smoothing the contact of the packing 5 and the cable 1, and further prevents gas from leaking in the direction of a bridged pipe 2 by passing the clearance of the packing 5 from the cooling pipe 3.
