Abstract: An object of the present invention is to enhance the capacity of a turbomolecular pump. A turbomolecular pump is a composite-type vacuum pump that combines a blade portion and a thread groove portion. Openings are formed at a joint portion between a rotor blade holding portion that holds rotor blades and a stepped portion that holds a rotor cylinder portion, such that the openings span both the rotor blade holding portion and the stepped portion. Part of the gas that is evacuated by the blade portions is evacuated by a thread groove portion that is formed of the rotor cylinder portion and a stator thread groove, and the rest of the gas is led into the rotor cylinder portion via the openings, and is evacuated by a thread groove portion that is formed of the rotor cylinder portion and another stator thread groove. Stress derived from rotation of a rotor can be withstood when the openings are formed at the joint portion between the rotor blade holding portion and the stepped portion.

Abstract: A vacuum pump is provided in which gas molecules in a vacuum chamber are sucked and exhausted by the rotational motion of a rotor rotatably supported in a pump case. At least one nickel alloy layer is disposed on a surface of at least one component defining a flow path in the vacuum pump for increasing a resistance of the component to corrosion due to a corrosive effect of a gas flowing through the flowpath. A nickel oxide is formed on a surface of the nickel alloy layer and has a higher emissivity than that of the nickel alloy layer for increasing a quantity of heat radiated from the surface of the component when the component is heated during operation of the vacuum pump.

Abstract: In a case where a desired radio frequency channel is searched over a plurality of radio frequency channels through manual switching, a received data error detection section 12 detects an error rate of radio data, and an electric field detection section 11 detects a field strength. System information comparison section 6 detects a match or mismatch between the system information of the radio frequency channel and the system information of a wireless selective paging receiver. A display section 3 indicates the result of such detection in the form of an at-a-glance list in decreasing order of receiving probability, thereby enabling the user to select a radio frequency channel having a higher degree of reliability. Further, radio frequency channels which will be covered by a receiving area, system information on each of the radio frequency channels, and area information are stored so as to become associated with one another.

Abstract: A message erasing method for a wireless communications device having a paging function, the method including a step of indicating received messages according to chronological order (on an LCD display); a step in which the user views the display and specifies the position of a message to be erased (by means of a jog dial); and a step of erasing all the messages received before the specified message (by means of a jog dial). By use of this method, the user can readily erase a plurality of unneeded messages.

Abstract: Group identification codes, names of parties to be sent, and telephone numbers of the pagers of the parties to be sent are stored in groups in memory 3 of a selective pager. At the time of transmission of a message, telephone numbers of a specified group and a message to be sent for the group are selected from the memory. The telephone numbers and the message are alternately sent to a DTMF signal generation section 8, which converts the telephone numbers and the message to DTMF signals. The DTMF signals are then converted into acoustic signals by means of a speaker 9 and are continually transmitted by way of a transmitter of a telephone set. As a result, a group call can be implemented without involving laborious operations, such as transmission of the telephone numbers and the message one by one.

Abstract: Messages received through information delivery are classified by a message identification section. The thus-classified messages are stored into a specified folder by means of a folder management section and are managed for each level in a hierarchy. When a new message is stored into the specified folder, a folder setting section causes a paging control section to page the user by means of a speaker, a vibrator, or an LED or causes a display control section to display the arrival of a message on an LCD. So long as the folder is set to a shortcut folder, a desired information item can be read in a prioritized manner.
