An electric compressor includes a housing including a compression part housing, a shaft support housing, and a motor housing fastened by a plurality of fastening members. A peripheral wall has a plurality of thick-walled portions that protrudes inwardly in a radial direction and through which their associated fastening members are inserted. The fixed scroll base plate has a plurality of protruded portions each protruding outwardly in the radial direction and disposed between the thick-walled portions in a circumferential direction. The fixed scroll base plate has a plurality of pillar portions each extending from the protruded portions toward the shaft support housing in the axial direction and spaced from each other in the circumferential direction. The elastic plate is held at a plurality of spots by the plurality of pillar portions and the shaft support housing.

Electric compressor

A scroll type compressor includes a housing, a fixed scroll cooperating with the housing to define a discharge chamber, a movable scroll cooperating with the fixed scroll to define a compression chamber, and a shaft support member cooperating with the movable scroll to define a back pressure chamber. Fluid in the compression chamber is supplied to the back pressure chamber. The back pressure chamber and the discharge chamber communicate with each chamber through a relief passage. A check valve is disposed in the relief passage, and the check valve allows the fluid to flow from the back pressure chamber to the discharge chamber, when back pressure of the back pressure chamber is higher than discharge pressure of the discharge chamber.

Scroll type compressor

A compressor includes a housing, a stationary block, a drive shaft, a motor mechanism, a stationary scroll, and a movable scroll. The stationary block is fixed to the housing and is arranged between the motor mechanism and the movable scroll. The motor mechanism includes a stator and a rotor. The drive shaft is provided with a balance weight. The balance weight extends in the radial direction of the drive shaft and is arranged between the stationary block and the stator. The stator includes a stator core and a coil end. The balance weight covers a part of the coil end in the radial direction and the axial direction of the drive shaft.

Motor-driven compressor

A scroll compressor includes a housing, a rotary shaft, a movable scroll, an eccentric shaft, an opposed wall, a looped elastic plate, a looped support portion, an annular protrusion, a back pressure chamber, and a back pressure supplying groove. The distance in the radial direction of the rotary shaft from the rotation axis of the rotary shaft to then outer end of the back pressure supplying groove in the radial direction of the rotary shaft is shorter than or equal to the distance obtained by subtracting the distance in the radial direction of the rotary shaft between the rotation axis of the rotary shaft and the axis of the eccentric shaft from the distance in the radial direction of the rotary shaft from the axis of the eccentric shaft to the part of the protrusion that contacts the elastic plate.

Scroll compressor

A terminal device for assisting operation of a plurality of eyeglass manufacturing apparatuses which are used for performing different processes in manufacturing eyeglasses includes: a communicating device configured to communicate with the plurality of eyeglass manufacturing apparatuses; a processor; and memory storing computer readable instructions, when executed by the processor, causing the terminal device to execute: a setting instruction for setting, according to a process, a specific eyeglass manufacturing apparatus from the plurality of eyeglass manufacturing apparatuses as an eyeglass manufacturing apparatus of which the operation is assisted; and a controlling instruction for controlling the communicating device to send an operating signal input in the terminal device to the specific eyeglass manufacturing apparatus set by the setting instruction or controlling the communicating device to receive an input signal input in the specific eyeglass manufacturing apparatus set by the setting instruction.

Terminal device and terminal control program

An eyeglass lens processing apparatus includes: a lens rotation unit configured to rotate a lens chuck shaft; a processing tool rotational shaft to which a processing tool is attached; a shaft-to-shaft distance change unit that includes a carriage which holds the lens chuck shaft or the processing tool rotational shaft and is movable in a direction where a shaft-to-shaft distance between the lens chuck shaft and the processing tool rotational shaft changes by driving a motor, a movement member that is moved in the shaft-to-shaft distance direction, a connection member that connects the movement member and the carriage, and a deformation detecting sensor configured to detect a deformation of the connection member; and a controller configured to control the driving of the motor based on a detection result of the deformation detecting sensor.

Eyeglass lens processing apparatus

An eyeglass lens processing apparatus includes: a mode selector for selecting an auxiliary lens processing mode; an eyeglass data input unit for inputting a first target lens shape of the eyeglass lens and a right target lens shape-to-left target lens shape distance; a first hole data input unit for inputting a position of a first hole, to which a first magnet is attached; a determination unit which determines second target lens shape of the auxiliary lens, a position of a second hole to which a second magnet is attached, positions of third holes to which a bridge is attached; and a processing controller which processes the auxiliary lenses based on the second target lens shape data, and drills the auxiliary lenses based on the second and third hole positions in the auxiliary lens processing mode.

An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens, includes: a lens rotating shaft which holds and rotates an eyeglass lens to be processed; an abrasive wheel rotating shaft movable between a retracted position and a processing position; a chamfering abrasive wheel which is attached to the abrasive wheel rotating shaft and which chamfers the lens while receiving a processing load from the lens during processing; a detecting unit which detects the load to the chamfering abrasive wheel; and a control unit which issues a control signal for relatively moving the lens and the chamfering abrasive wheel one from another to reduce the processing load if the detected processing load is higher than a predetermined first level and for continuing the chamfering, and which issues a control signal for ending the chamfering if the detected processing load over the entire periphery of the lens is lower than a predetermined second level.

An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens, includes: a lens rotating unit having rotating shafts for holding and rotating the lens; an abrasive wheel; an abrasive wheel state detecting unit for detecting a lowered processing performance of the abrasive wheel; and a notifying unit for notifying that dressing for the abrasive wheel is required based on a result of detection by the abrasive wheel state detecting unit.
