An object is to provide polycrystalline diamond applicable to diverse applications; and a water jet orifice, a stylus for gravure printing, a scriber, a diamond cutting tool, and a scribing wheel that include such polycrystalline diamond. This object is achieved by polycrystalline diamond obtained by converting and sintering non-diamond carbon under an ultrahigh pressure and at a high temperature without addition of a sintering aid or a catalyst, wherein sintered diamond grains constituting the polycrystalline diamond have an average grain diameter of more than 50 nm and less than 2500 nm and a purity of 99% or more, and the diamond has a D90 grain diameter of (average grain diameter+average grain diameter×0.9) or less.

A connector (10) has a housing (20) that is connectable with a mating connector (90). A sliding force multiplying mechanism can slide relative to the housing (20) in a direction intersecting a connecting direction for proceeding with a first part of a connecting operation. A rotating force multiplying mechanism then can be rotated relative to the housing (20) for proceeding with a second part of the connecting operation. The sliding force multiplying mechanism and the rotating force multiplying mechanism operate separately and are formed on a single lever (40).

A housing (10) has a lock arm (20) that pivots about a fulcrum (23) that is rearward of a pivoting portion (24) of the lock arm (20). A detection terminal (50) has a rear support (52) supported on the housing (10) rearward of the pivoting portion (24). An action portion (54) of the detection terminal (50) is engaged with the pivoting portion (24) and displaces with the pivoting portion (24). The lock arm (20) deforms during connection of the housing (10) and a mating housing (90) so that contacts (53) of the detection terminal (50) are not in contact with mating detection terminals (97). However, the lock arm (20) returns resiliently when the housings (10, 90) are connected properly so that the contacts (53) contact the mating detection terminals (97).

Various types of diamond tools are provided by utilizing the fact that a synthetic single crystal diamond for use in a tool having a nitrogen content of 3 ppm or less exhibits an enhanced hardness in a (100) plane in a direction and simultaneously the reduction in defects. The above synthetic single crystal diamond is synthesized by the temperature difference method under an ultra high pressure at high temperature and contains, in its crystals, nickel introduced by atomic substitution or boron and nickel introduced by atomic substitution.

A movable member (36) is located at a malfunction preventing position and a pair of functional terminals (25) are shorted by a shorting terminal (50) unless two housings (10, 20) are properly connected, whereas the movable member (36) is moved to a connection detecting position and the shorting terminal (50) shorts a pair of detection terminals (14) at the same time as being disengaged from the pair of functional terminals (25) when the two housings (10, 20) are properly connected. Since the shorting terminal (50) is commonly used to short the pair of functional terminals (25) for the malfunction prevention and the like and to short the pair of detection terminals (14) for the detection of a connected state of the two housings (10, 20), the number of parts can be reduced.

A mailing list server and a mail re-sending method thereof with which, when a mail recipient has been unable to decrypt a mail, it is possible to re-send the mail compatibly encrypted in a form such that the recipient can decrypt it without fail. A mail re-send request from a member is made by HTTP, received by a web server 20, and processed by an application server 21. For example, re-send request information is sent to the web server 20 by a mailing list member, using an input form of a web page 303 from the web server 20. The application server 21 determines an encryption method on the basis of a user encryption method specification included in the mail re-send request. A sending part 101 encrypts the mail by the determined method and sends it to the member's address.
摘要:
A connector device is provided with a box-shaped casing (50), a female housing (30) mounted into the casing (50) and displaceable between an initial position and an end position, and a slide (70) that is in the form of a frame having an operating portion (72) and mounted in the casing (50) for movement between a retreat position where a clearance exists between the operating portion (72) and the casing (50) and an advance position that narrows or eliminates the clearance. Before an operation of connecting both male and female housings (10, 30) is started, a protector (90) is inserted into a fitting space (91) between the operating portion (72) of the slide (70) and the casing (50). The slide (70) is held at the retreat position and the female housing (30) is held at the initial position by the protector (90).
摘要:
In a mobile communication system in which a compressed mode can be activated at the time of hand over, or when a base station which the mobile station is in communication with is switched to another base station, the distance between the mobile station and at least one of the plurality of base stations which is currently in communication with the mobile station is measured; and the activation of the compressed mode is controlled according to the measured distance. The activation of a compressed mode is controlled according to the distance between the base station and the mobile station.
摘要:
A terminal fitting (T) has a rectangular tube (10) with a bottom plate (12). A resilient contact (25) extends back into the tube (10) from an end of the bottom plate (12). A base portion (33) is formed at the front end of the bottom plate (12) and is made narrower than the bottom plate (12) by cutting away the left and right edges. A bulge (34) bulges out from a lateral edge of the base portion (33) and narrows an area of an opening between the base portion (33) and the right side plate (13R). Thus, external matter is less likely to intrude into the rectangular tube (10) through the opening even if the resilient contact (25) is narrow. Additionally, the base portion (33) is reinforced by the bulge (34). Thus, the base portion (33) is less likely to be deformed by external matter.
