摘要:
A pressure water absorption inhibitor for lightweight aggregates which comprises an aqueous dispersion of a polymeric substance having a viscosity which permits the aqueous dispersion to enter the fine pores in the surface layer of a lightweight aggregate and which dispersion is capable of being thickened to a viscosity of not less than 50 times the viscosity before thickening by elevation of the pH.
摘要:
A portable unit that may be called from a base station through a radio control channel by a succession of terminating call signals that is sent through the control channel from the base station to the portable unit for a first or restricted time duration (T.sub.1), selected in consideration of a battery saving period of a battery saving operation carried out in the portable unit. Within the battery saving period, the portable unit is put into transient active and inactive states during a first time interval and a second time interval, respectively. Selection is made so that the first time duration is longer than the second time interval to receive at least one of the terminating call signals within the first time duration in the portable unit. The base station monitors an acknowledgement signal for a second time duration (T.sub.2) after the lapse of the first time duration and interrupts the control channel when the acknowledgement signal is not received within the first and the second time durations. In the portable unit, the battery saving operation is released when the presence of the terminating call signals is detected by a squelch circuit.

A mobile terminal as a mobile terminal includes a storage unit which stores an action pattern record table having at least one action pattern registered preliminarily in correlation with addressee information, a control unit which obtains position information of the mobile terminal via a GPS antenna to identify the action pattern based on the position information obtained by a receiver in reference to the stored action pattern record table responding to the request for activating a redial function, and a main display which displays the addressee information in accordance with the priority of the addressee information correlated with the action pattern identified by the control unit in reference to the action pattern record table.
摘要:
If a print misregistration amount on a sheet is larger than a predetermined threshold before determining whether a printed image is appropriate or not, an abnormal status of the image printed on the sheet is detected without correcting image data for inspection. A control method for controlling a detecting apparatus for inspecting a print status of an image printed on a sheet by a printing apparatus includes detecting, in a case where it is determined that a print misregistration amount of the image printed on the sheet with respect to the sheet is larger than a predetermined threshold, an abnormality of the print status of the image read by a reading unit without performing correction.
摘要:
The present invention provides an antenna that is small in size and has band frequencies corresponding to multibands, and a wireless communication apparatus including the antenna. The antenna according to the present invention has two radiation elements 12a and 12b connected to a ground plate 11 via a shorting pin. The two radiation elements 12a and 12b each have a lower arm and an upper arm that are formed through bending. The lower arm is connected to the shorting pin and is located closer to the ground plate 11 than the upper arm is. At least one of the lower arm and the upper arm has a meandered structure.
