Abstract: Provided is: a layered body wherein a sheet surface has slight adhesiveness, enabling easy temporary securing of a semiconductor chip, or the like, that has been diced, onto a semiconductor substrate, and wherein permanent adhesion to an adhered object is expressed through post-curing; a layered body that includes the same; a semiconductor device that uses the same; and a method for manufacturing the semiconductor device. A silicone-based adhesive sheet is disclosed herein, wherein, prior to heating, the delamination mode of the adhesive surface from a non-adhesive substrate is interfacial delamination, and after heating of the adhesive surface in a range of between 50 and 200° C., the delamination mode of the adhesive surface from another non-adhesive substrate changes to cohesive fracturing, and exhibits permanent adhesion.

Abstract: Provided is an integrated dicing die bonding sheet having excellent storage stability and stress relaxation properties, having no problems such as chip flying, chipping, cracking, and the like during a dicing process, and having excellent production efficiency; and a method of manufacturing a semiconductor device (particularly including a MEMS device) using the same. An integrated dicing die bonding sheet including a base film, and a silicone-based adhesive sheet having an adhesive surface adhered to the semiconductor wafer, wherein at a stage after dicing the semiconductor wafer and prior to heating, the base film can be interfacially peeled from the silicone-based adhesive sheet, and after the adhesive surface is heated within a range of 50 to 200° C., a peeling mode of the adhesive surface from another non-pressure-sensitive adhesive base material changes to cohesive failure, exhibiting permanent adhesion.

Abstract: Signals with transmission frequencies from hand sets are received by a receiver. The whole frequency spectrum including the received signals whose frequency is converted by the receivers inverted by a signal processor. Then, the received signals included in the frequency spectrum inverted by the signal processor is converted by a transmitter and retransmitted as signals with reception frequencies of the hand sets. By using this communication apparatus, a communication system with fixed duplex intervals can be employed with a simple configuration at a low cost, transmission/reception frequencies can be readily set and duplex conversation between hand sets can be achieved.

Abstract: A main-sub relation setting apparatus for setting a main-sub relation of a cordless telephone system including a main unit and one or more sub units connected to the main unit is provided. The main unit is placed at a first location, and the main-sub relation setting apparatus and a sub unit to be newly connected to the main unit are placed at a second location different from the first location. The main-sub relation setting apparatus includes a retail outlet terminal reading main unit information for the main unit to identify itself, and a setting terminal connected to a sub unit to be newly connected to the main unit and to the retail outlet terminal, for writing the main unit information read by the retail outlet terminal to a memory of the sub unit to be newly connected to the main unit.

Abstract: A primary object of the present invention is to provide an information presentation device capable of presenting operation support information such as operation process and an input operation procedure to help a user in doing input operation with an electronic apparatus and simplifying the presentation according to a degree of the user's acquaintance with the operation of the apparatus, whereby enabling the user to more effectively use the apparatus with no unnecessary waiting time and with an increased efficiency of using the capacity of the memory device. A presentation control unit processes the presentation data for supporting the user's inputting operation.

Abstract: The invention makes efficient use of the function of a video telephone to store incoming calls. A caller image is stored in a display storage portion during a call, and the display of the image with an image display portion is continued after the communication. When the user sees the display portion, the user can confirm with one glance from who a video telephone communication was received while the user was out. It is also possible to store caller images while successively increasing the number of partitions into which the screen of the image display portion is partitioned whenever an image is recorded, and successively increasing the empty display space.

Abstract: An object of the present invention is to integrate circuits for frequency conversion processing of an input signal of the GHz band. In a receiver, an input signal from an antenna is amplified after components thereof outside a frequency band for communication network being removed, and is supplied to an arithmetic processing unit. A plurality of sampling circuits within the arithmetic processing unit respond to a plurality of clock signals of which frequencies are equal and of which phases are different, respectively, and sample the input signal after amplification. The sum-of-products arithmetic unit within the arithmetic processing unit responds any one of the clock signals and performs sum-of-products operation periodically using a plurality of sample signals exhibiting the sampling results of all the sampling circuits, respectively.

Abstract: A cordless telephone includes a portable unit having chargeable secondary batteries as a power source in which to minimize the power consumption, signals are received intermittently to limit the operating time of the built-in receiver. The portable unit includes a detecting device for detecting the charging state of the secondary battery, and swtiching device for switching the receiving action of receiver to a continuous receiving action while the charging state of the secondary battery is being detected by the battery charging detecting device. Accordingly, the power source of the receiver, while the secondary batteries are being charged is fed from the power source for charging through the secondary batteries. Thus, the receiving action during this period may be set in continuous receiving action. Hence, it is possible to reply from the portable unit without delay to a call from a base unit during the charging.
