Abstract: Provided is an instrument holder that allows an instrument to be smoothly, safely, and hygienically handled by holding the instrument in a standing posture when in use and by holding the instrument in a posture not allowing the instrument to easily contact a practitioner when not in use. A holder portion 15 of an instrument holder 12 has a pair of supporting body portions 16, a rotational body portion 23 that is supported by the supporting body portions 16 and that is rotatable, and a holder body portion 31 that is attached to the rotational body portion 23. The holder portion 15 alternately changes between a rearwardly tilting holding state and a forwardly tilting waiting state due to rotation of the rotational body portion 23.

Abstract: An instrument hose support device includes a rod that supports an instrument hose at a position higher than an instrument that is held by a holder, a pulley support portion that is supported by a distal end of the rod, a pulley that is supported by the pulley support portion and over which the instrument hose is looped. The distal end has a groove in which a taper is formed. A first member of the pulley support portion has a shaft protrusion, and a gap is formed between the shaft protrusion and the groove. The gap serves as the range of motion of the pulley support portion, and the pulley support portion follows the movement of the instrument hose and, relative to the rod, swings freely toward the front and the back and toward the sides and rotates freely with a movable axis (X) as an axis.

Abstract: A moving unit includes a housing, a rotary unit to which a rod part is attached, a spring that generates a torque when the rod part is tilted down or tilted up about a rotation axis on the side on which a base portion of the rod part is located, and a torque adjustment unit that is capable of adjusting a torque by deforming the spring. The torque adjustment unit includes a spring deforming portion that deforms the spring in a direction in which the spring is wound up and a spring fixing portion that keeps a torque constant by coming into contact with the spring deforming portion and fixing the spring deforming portion in place.

Abstract: A permanent wave treatment method is provided in which the difference between wet and dry wave shape is small. A first permanent wave agent is applied to swell and soften hair wound around a rod, the first permanent wave agent is rinsed off, a chemical agent spray member 42 is moved back and forth inside a hood 2 while uniformly spraying the entire hair with a chemical agent comprising an intermediate treatment agent that contains ascorbic acid salt; while heating with a blower 12, the ascorbic acid salt is adhered to the hair wound around the rod, and the moisture is maintained.

Abstract: A toilet seat for use with a Western-style toilet bowl. The seat has a generally-oval, endless base that compliments the shape of the toilet bowl rim. A deflector is fixed to the bottom surface of the base and extends downwardly adjacent the inside surface of the bowl rim. The deflector covers the interior gap between the bottom of the seat and the top of the bowl rim.

Abstract: A permanent wave treatment apparatus comprises: a housing 3; a blower 1 which is installed within the housing to suck air and blow air; a steam separator 2 which is provided on the blower to remove water content from air sucked by suction force of the blower; an outlet hole formed in the housing through which air is spouted from the blower; hoods F mounted on the housing such that they are capable of being opened/closed freely; a plurality of rods R on which the hair of an object person is to be wound and in which air vent holes are formed; tubes 4 connected to the rods so as to keep the interior of the rods in a negative pressure by the suction force of the blower; and extraction member 5 which holds a plurality of the tubes such that they are capable of being extracted freely.

Abstract: An automatic hair washing machine including a sink in which a head portion of a user is laid, the sink having an enclosed space that is formed when the head portion is laid in the sink, a nozzle link unit for jetting liquid containing at least one of washing water and cleaning agent liquid, and a mist spraying unit for spraying mist into the enclosed space.

Abstract: A permanent wave treatment device has a heating means (3) for setting hair of a to-be-treated person in a heated environment, a rod (R) on which the hair is wound and that is formed so that air can flow through it, a suction means (4) for making the pressure inside the rod negative, and a connection means (7) for connecting the rod and the suction means.

Abstract: An existing barber or beauty salon chair, in which each of a chair and a shampoo bowl is formed to the base integrally, has a problem that an practitioner cannot stand behind a customer, thereby being forced to take an uncomfortable posture to prepare shampoo or the like or thereby making it impossible to perform operation other than the shampoo, such as a massage or a beauty operation. To solve the above problems, a barber or beauty salon chair is characterized in that a chair 4 with a backrest 42 allowing a recline angle to be adjustable is attached in a rotatable manner to a base 2 of an elevating device 1 while a shampoo bowl 3 is attached to the base in a position to which an upper surface of the backrest in a deeply reclined condition comes close.

Abstract: A chair elevating/lowering hydraulic device includes at least a foot pump 3 which absorbs oil by an ascent of an operation lever 1, which discharges oil stored by a stepping-on of the operation lever, and which discharges stored oil by a stepping-on of the operation lever to a lowest position, a check valve 5 which is opened by the oil pressure of the oil discharged from the foot pump, which is opened when the foot pump is lowered to the lowest position, and which allows the oil from the non-return side to pass to allow it to return to an oil tank through the foot pump, an elevating/lowering cylinder 7, and an accumulator 6.

Abstract: In order to solve a problem in a conventional device in which an operation lever is stepped on by a foot to supply oil to an elevating/lowering cylinder, in that since oil supply to the elevating/lowering cylinder is stopped every time the operation lever is stepped on, a seat part stops every time oil supply to the hydraulic cylinder is stopped, and in that such a device gives the person who receives technician's work shock and an uncomfortable feeling, a chair elevating/lowering hydraulic device is composed of a foot pump 3 which absorbs oil by an ascent of an operation lever 1, which discharges oil stored by a stepping-on of the operation lever, and which discharges stored oil by a stepping-on of the operation lever to a lowest position, a check valve 5 which is opened by the oil pressure of the oil discharged from the foot pump, which is opened when the foot pump is lowered to the lowest position, and which allows the oil from the non-return side to pass to allow it to return to an oil tank through the fo
