Abstract: A massage chair is adapted to give a massage to a user using a massaging element attached to a massaging unit. The massage chair comprises a body-shape-information acquisition section for acquiring body-shape information of the user based on loads imposed on the massaging element from respective regions of the user, a shoulder-position detection section for detecting a shoulder position of the user based on the body-shape information, and a shoulder-position identification section. The shoulder-position identification section is operable to thrust the massaging element in a direction for a target protrusion distance at the detected shoulder position while measuring a load imposed on the massaging element. Then, the shoulder-position identification section is operable, based on the measured load, to determine whether the detected shoulder position is a true shoulder position.

Abstract: A chair type massager includes a seat part on which a person to be treated sits on, a backrest part with a reclining mechanism to perform a raising/tilting operation, and right and left armrest parts in which the arms are inserted. The massager further includes air bags provided at the armrest parts, the air bags holding the arms placed in the armrest part by being swelled by air supplied from an air supply pump; a control part for controlling the raising/tilting operation of the backrest part and the air supply to the air bags; and a manipulation part for giving instructions to the control part. When controlling the reclining mechanism to tilt the backrest part in response to the instructions from the manipulation part to perform the arm stretch, the control part controls the air supply pump to supply air into the air bags intermittently.

Abstract: An exercising apparatus includes a movable unit on which a user straddles and a driving unit for driving the movable unit. The driving unit changes a state of the movable unit to provide the user with an exercising load. A storage part stores corresponding relationships between the states of the movable unit and the messages, and a state detector detects the state of the movable unit at approximately the same timing as the output timing determined by an output timing determination part. A message output part outputs messages corresponding to the user's postures repeatedly during a period of providing the user with an exercising load. The message output part extracts the message corresponding to the state of the movable unit detected by the state detector from the storage part and outputs the extracted message at the output timing determined by the output timing determination part.

Abstract: A massage chair of the present invention includes an electric reclining mechanism for moving a backrest into different sloping positions, left and right holding mechanisms for respectively holding user's left and right forearms, and a controller for controlling operations of the mechanisms. The controller separately controls operations of the electric reclining mechanism and the left holding mechanism as well as operations of the electric reclining mechanism and the right holding mechanism. When controlling the former operations, the controller controls (A) allow the left holding mechanism to hold the left forearm, (B) allow the electric reclining mechanism to recline the backrest to any of the different sloping positions, (C) allow the electric reclining mechanism to raise the backrest to any of the different sloping positions, and (D) allow the left holding mechanism to release the left forearm. Similarly, the controller controls the latter operations.

Abstract: A massage chair including an electric reclining mechanism for moving a backrest into different sloping positions, a holding mechanism for holding at least one forearm of a user to fix to the base side, and a controller that controls operations of these mechanisms. The controller allows the holding mechanism to hold the at least one forearm and allows the electric reclining mechanism to move the backrest into at least one sloping position before moving the backrest into a final position. An inclination of the at least one sloping position from a sloping position of the different sloping positions when the at least one forearm is held by the holding mechanism is smaller than an inclination of the end position from a sloping position of the different sloping positions when the at least one forearm is held by the holding mechanism.

Abstract: In a chair massager, a stretching operation is performed with utilizing airbags which is expanded and shrunk, effectively. Airbags 3a, 3b, 4a, 4b, 5a and 5b which perform air-massage by expansion and shrinkage are disposed on a shoulder portion 3 and a lumbar portion 4 of a backrest 2, and a seat 5 of a main body 1 of the massager. Arm airbags 6a and 6b which perform air-massage by expansion and shrinkage are disposed on armrests 6 at both sides of the seat 5. In the stretching operation, for example, a shoulder airbag 3b on the shoulder portion 3 is expanded and shrunk in a state that an arm airbag 6a on one armrest 6 is expanded to hold an arm of the user 200. Thereby, the balance of a human body of the user 200 is broken down so that high stretch effect can be obtained.

Abstract: A variable capacity compressor for use in a heat-exchange circuit. A pressure responsive valve is provided in a communication passageway extending between a low pressure chamber and a pressure controlled chamber. The pressure responsive valve is operative in response to pressure within the low pressure chamber for opening and closing the communication passageway to control pressure within the pressure controlled chamber, thereby varying the capacity of the compressor in such a manner as to reduce the capacity when the pressure within the low pressure chamber decreases to a level lower than a predetermined value. An electrically operated control device is operative in response to pressure or temperature of refrigerant gas in an evaporator of the heat-exchange circuit for maintaining the capacity large independently of operation of the pressure responsive valve, even if the pressure within the low pressure chamber decreases to a level lower than the predetermined value.

The pressure-control valve comprises bellows variable in length with a change in the magnituted of suction pressure, a valve body attached to one end of the bellows, a first movable member attached to the other end of the bellows, a first spring urging the valve body in the closing direction, a second movable member which is brought into or out of urging contact with the first movable member in response to at least a change in the discharge pressure, and a second spring interposed between the second movable member and a spring seat.

A high pressure chamber formed in the cylinder head is partitioned by a partition plate into a first high pressure chamber communicating with a plurality of discharge holes in the valve plate by means of a discharge valve and a second high pressure chamber communicated with a discharge opening formed in the cylinder head, and the pulsating is reduced by the passing of the gas through the first high pressure chamber and the second high pressure chamber.

Abstract: In a swash-plate type rotary compression, a pair of cylinder blocks are formed of an aluminum alloy containing 16 to 20 weight % silicon. A ring made of a synthetic resin having wear resistance and slidability is fitted in a ring groove formed in a sliding surface of each of pistons which is brought into sliding contact with the corresponding cylinder bore, or a coating layer formed of a ferrous metal is provided on the above sliding surface. A drive shaft is fitted in a central bore in each of the cylinder blocks such that radial load exerted by the drive shaft is directly borne by an inner peripheral surface of the central bore, and an oil passageway supplies lubricating oil to a clearance between an outer peripheral surface of the drive shaft and the inner peripheral surface of the central bore.
