摘要:
A mechanical pencil having a rotational drive mechanism which gradually rotates a writing lead on application of writing pressure and allowing rotational operation of the writing lead to be known reliably. First and second cam faces 6a and 6b are respectively formed at one end face and the other end face of a rotor 6 in an axial direction, and first and second fixed cam faces 13a and 14a arranged on the body cylinder side so as to respectively face the first and the second cam faces are provided to form the rotational drive mechanism for the writing lead. A plurality of grooves 8a in the axial direction are formed at a slider 8 of a pipe end 7 which projects forwardly from a body cylinder 1. Therefore, the user can see the grooves 8a (provided for the slider 8) rotated by rotation. of the rotor 6.

A boom control valve and a pulsation absorption control valve are provided in the halfway point of a center bypass line. The pulsation absorption control valve is arranged in a position downstream of the boom control valve. The pulsation absorption control valve is switched to a blockade position and a communication position by a pilot pressure from a remote control valve. The pulsation absorption control valve is constituted such that one main line out of a pair of main lines is communicated with or blocked off from an accumulator via one communication line and the other main line is communicated with or blocked off from the side of a tank via the other communication line. The accumulator is operated as a dynamic damper at the traveling of a vehicle. This arrangement enables the construction of the communication line to be simplified, thus improving operability at assembling.

For an apparatus determining whether or not an HDD is started by barometric pressure information or the like, there are provided a navigation apparatus, an operation control device, an operation control method, and an operation control program, that enable shortening of a time from a power-on to starting-up of the HDD.The present application is the operation control device which controls the operation of the HDD by giving an instruction to the HDD to control the operation of the HDD, the operation control device including: a recording means for recording a previous closing information indicative of whether or not the operation of the operation control device normally ends by a previous power-off and an operation control means for giving an instruction of starting the operation to the HDD in a case where the operation has been normally ended at a time of starting the operation control device by the power-on.

A backrest structure capable for a vehicle having seats that are supported on a vehicle body frame via a seat frame as a seat support member. Each of the seats includes a seat back as a backrest supporting a back of a driver. The seat back is removably mounted in the seat frame, thereby permitting positional adjustments in vertical and longitudinal directions to fit a body type of the driver. The resulting configuration makes driving of the vehicle easier.

The present invention is a vertical boat for heat treatment having an auxiliary supporting member removably attached to each of supporting parts of a boat body, the auxiliary supporting member on which a substrate to be treated is to be placed, in which the auxiliary supporting member has a guiding member attached to the supporting part and a substrate supporting plate on which the substrate to be treated is to be placed, a hole is formed on an upper surface of the guiding member, the substrate supporting plate is inserted and fitted into the hole of the guiding member so as to be fixed, a height position of a placing surface for the substrate to be treated is higher than a height position of the upper surface of the guiding member, the substrate supporting plate is composed of silicon carbide and the guiding member is composed of quartz.
摘要:
A chuck (4) for grasping a writing lead and a rotor (6) arranged to be movable together in a direction of rotation and an axial direction within a body cylinder (1). A rotational drive mechanism for the writing lead is formed such that first and second cam faces (6a) and (6b) are respectively formed at one end face and another end face of the rotor in the axial direction, and first and second fixed cam faces (13a) and (14a) are arranged on the body cylinder side to face the above-mentioned first and second cam faces respectively. Retreat operation and forward movement (cushion action) of the writing lead by writing pressure are provided with a damping effect by sticky grease (19) interposed between a stopper (16) and a torque canceller (17). As a result, a sense of uncomforting, when writing, generated in conjunction with the cushion action can be reduced.
