摘要:
There is provided an alternative vehicle guiding system wherein a communication sever system receives a fault condition information from vehicles and also transmits the necessary information to the navigation system of an alternative vehicle in order to prevent the damage of loads by quickly guiding the alternative vehicle to the fault generating vehicle position and then realizing smooth transfer of remaining work to the alternative vehicle. The navigation system, fault monitoring means and vehicle communication means are respectively provided in the vehicles for transportation work and the center server system is also provided to transmit the vehicle distribution information to the vehicles. When a fault is generated in the vehicle, the communication server system receives the information from this vehicle and the navigation system of the alternative vehicle displays the transmitted information. Thereby, the alternative vehicle can always be distributed smoothly without any manual operation, the time required until the alternative vehicle arrives and the work transfer time can be shortened and adverse effect on the loads and successive load distribution work can be prevented.

A method for treating a circulatory disease or condition in a mammal, which entails administering to the mammal an effective amount of a compound of the formula (I) or a pharmaceutically acceptable salt thereof: wherein the ring P represented by is a pyrrole ring having the following structure: wherein R1 represents C1-C8 alkyl, C3-C8 cycloalkyl, C4-C8 cycloalkyl-alkyl, C6-C14 aryl or C7-C22 aralkyl, which are optionally substituted; and R2 represents H or C1-C8 alkyl, which is optionally substituted; the dashed line indicates the presence or absence of a bond; and, when the bond is present, Z2 is not present and Z1 represents H, but, when the bond is absent, Z1 and Z2 are both H; Z1 represents H and Z2 represents a group OR3, in which R3 represents H, C1-C8 alkyl, or C7-C22 aralkyl, which are optionally substituted; Z1 and Z2 both represent groups SR4, in which R4 represents C1-C8 alkyl or C7-C22 aralkyl, which are optionally substituted; or Z1 and Z2 are combined together to represent O, a group NOR5, in which R5 represents H, or C1-C8 alkyl or C2-C3 alkylenedithio, which are optionally substituted; A represents alkylene, alkenylene or alkynylene; and Y represents a group in which W is CH, C═ or N, m is for 0 or 1, n is for 1, 2 or 3, G is O, S, C═O, sulfinyl, sulfonyl, alkylene, alkenylene or acetal; E1 and E2 is H or C1-C8 alkyl; and D represents an aromatic hydrocarbon or an aromatic heterocyclic ring. The compound (I) has strong serotonin-2 receptor antagonistic action and low toxicity and less side effects, and is therapeutically useful in the treatment of circulatory diseases and/or conditions related thereto.
摘要:
An ink jet recording head includes energy generators for generating the energy used to discharge ink and a substrate on which a circuit electrically connected to the energy generators is formed. Also provided is a protective member on an insulating layer on the substrate above the energy generators. The area of a protective member which is in contact with the ink is made to be as small as possible.

A method for detecting an insulative condition of a protection layer of a substrate includes the steps of contacting an area of a surface of a protection layer to be detected with a liquid, and checking the electrical conduction between the liquid and a detection electrode which is electrically connected with an electrical element at an area on which the protection layer is not provided.
摘要:
A lip seal device for sealing the gap between a housing and a rotary shaft comprises a case surrounding the rotary shaft, a lip seal attached inside the case a, support for holding the lip seal on the outer circumferential portion thereof and a seal located on the outside circumferential surface of the case. The inner circumferential portion of the lip seal is curved toward the sealed fluid. The lip seal includes a sealing surface provided with an annular groove extending continuously in the circumferential direction of the rotary shaft so that the sealing surface has a first and second sealing portion, the contact pressure of the first sealing portion on the rotary shaft being lower than the contact pressure of the second sealing portion on the rotary shaft.
摘要:
A non-contact type seal device for a turbocharger in which lubricating oil is prevented from leaking into the compression chamber of the turbocharger over the entire range of rotational speeds thereof. The seal device of the invention includes a retainer mounted in a compression chamber of a housing of the turbocharger, a collar attached to a compressor wheel mounting portion of the rotor shaft of the turbocharger, and a ring provided on an inner peripheral surface of the retainer. An annular groove receiving the ring is formed in the outer peripheral surface of the collar. A first gap is formed between the outer peripheral surface of the collar and the inner peripheral surface of the retainer, while a second gap is formed between the inner surface of the annular groove and each of the inner and outer end surfaces of the ring. A threaded groove is formed in the inner peripheral surface of the retainer in opposition to the outer peripheral surface of the collar.
