Patent number: 11971504Abstract: A control device (10) includes a control unit (100). The control unit (100) controls a plurality of irradiation devices (20) that emit electromagnetic waves. The control unit (100) outputs a plurality of first periodic signals for respectively controlling movements of the irradiation directions of the electromagnetic waves to a first direction in the plurality of irradiation devices (20), and a plurality of second periodic signals for respectively controlling movements of the irradiation directions of the electromagnetic waves to a second direction in the plurality of irradiation devices. The periods of the plurality of first periodic signals are the same as each other. The effective repetition number of the movement of the irradiation direction to the second direction, while the irradiation direction is moved one period to the first direction, is the same for the plurality of irradiation devices.Type: GrantFiled: March 20, 2019Date of Patent: April 30, 2024Assignee: Pioneer CorporationInventors: Takehiro Matsuda, Toshio Maehara

Patent number: 11084155Abstract: Provided is a hydraulic striking device in which a reverse operation circuit and a forward operation circuit can switch connection states to a high pressure circuit and a low pressure circuit by means of an operation switching valve. Further, the hydraulic striking device is configured to be selectable between a reverse operation mode or a forward operation mode by operating the operation switching valve. A high/low pressure switching portion is provided with a shortening portion for reducing the time required for high/low pressure switching operation in piston front and rear chambers in association with retraction of a valve to be shorter than the time required for high/low pressure switching operation in the piston front and rear chambers in association with advancement of the valve.Type: GrantFiled: August 21, 2017Date of Patent: August 10, 2021Assignee: Furukawa Rock Drill Co., Ltd.Inventor: Toshio Matsuda

Patent number: 11034010Abstract: A hydraulic hammering device is capable of sufficiently transmitting blow energy to bedrock while further strengthening cushioning action and suppressing damage to equipment. The device includes a pushing piston disposed behind a transmission member and having a smaller propulsive force than that of a main body, a damping piston positioned behind the pushing piston to slide reciprocally forwards and backwards and having a greater propulsive force than that of the main body, a direction-restrictor in a high-pressure circuit between pushing and damping chambers, to which hydraulic fluid is supplied for providing the pistons with propulsive forces, and a fluid supply source. The direction-restrictor restricts an outflow from the chambers side to the fluid supply source side while allowing fluid inflow from the fluid supply source side to the chambers and the pushing chamber sides. A throttle in a drain circuit discharges leaked fluid from a sliding contact location to a tank.Type: GrantFiled: December 20, 2016Date of Patent: June 15, 2021Assignee: Furukawa Rock Drill Co., Ltd.Inventors: Tsutomu Kaneko, Masahiro Koizumi, Toshio Matsuda

Patent number: 10493610Abstract: A hydraulic hammering device that uses a scheme in which a front chamber is switched into communication with a low-pressure circuit when a piston advances, wherein occurrences of “galling” to the piston at a sliding contact portion with a front-chamber liner is reduced. The front chamber has the front-chamber liner fitted to an inner surface of a cylinder. A hydraulic chamber space communicating with the front chamber and filled with hydraulic oil is formed as a cushion chamber on the inner peripheral surface of a rear portion of the front-chamber liner. The cushion chamber has a second drain circuit (from first end face grooves to slits to second end face grooves), which is provided separately from a drain circuit that guides the hydraulic fluid passing through a liner bearing of the front-chamber liner to the low-pressure circuit.Type: GrantFiled: January 30, 2015Date of Patent: December 3, 2019Assignee: Furukawa Rock Drill Co., Ltd.Inventors: Masahiro Koizumi, Susumu Murakami, Toshio Matsuda, Tomohiro Goto, Shunsuke Echigoya

Patent number: 10150209Abstract: Provided is a hydraulic hammering device having improved hammering efficiency and of low cost. A piston has a valve switching groove between large-diameter sections thereof. A cylinder has three control ports at positions corresponding to the valve switching groove. A switching valve mechanism has a valve presser for always pressing a valve in one direction and also has a valve controller for moving, when supplying pressurized oil, the valve in the opposite direction against the pressing force of the valve presser. A valve control port communicates with the valve controller so as to supply the pressurized oil to the valve controller and is separated from a piston front chamber and a piston rear chamber. Only either a piston retraction control port or a piston advance control port communicates with the valve control port depending on advance or retraction of the valve switching groove.Type: GrantFiled: January 30, 2015Date of Patent: December 11, 2018Assignee: Furukawa Rock Drill Co., Ltd.Inventors: Toshio Matsuda, Tsutomu Kaneko
