Abstract: Users desiring to register as users access web server for personal computers 11 using terminal device 20, and run a member registration process by registering a member ID and password. When a user that has registered as a member wants to use the membership system service-providing site with a mobile telephone 21, the user accesses web server for mobile telephones 12. When an already-registered member ID and password are inputted to web server for mobile telephones 12, web server for mobile telephones 12 extracts identification information specific to the mobile telephone 12 and records it linked to the already-registered member ID and password. This process enables member information to be centrally managed on a membership system service-providing site that can be accessed from a terminal device and a mobile-telephone.

Abstract: An image recording and reproducing apparatus can record and reproduce both of a digital signal and an analog signal. Operations of a broadcast receiving apparatus and a recording and reproducing apparatus are integrated and superimposition of information on an analog image is realized during recording and reproduction of a digital signal. The broadcast receiving apparatus and the recording and reproducing apparatus communicate with each other to be able to set and obtain states of the opposite apparatus, so that one of the apparatus notifies information of the other apparatus to a user and causes the user to set the information in a picture having the same form as a picture used to notify a state of one apparatus to the user and to cause the user to set the state.

Abstract: Data after shifting is outputted from a output bus 9 by that, n-bit, data inputted to a input bus 1 is connected either to a first bus 3 or to a second bus 4, or to the both of them by a bus switching circuit 2, data either on the first bus 3 or the second bus 4 which is not connected to the bus switching circuit 2 is compensated by data compensating circuits 51, 52, a signal including a shift quantity and shift direction given from a shift quantity bus 6 is decoded by a decoder 7, and by performing plural-bit shifting by a MOS transistor array 8 of n numbers of line and n+1 numbers of column. Respective processings of logical shift, arithmetic shift and rotation are performed in both right and left directions by a single circuit configuration.

Abstract: A DC-DC converter comprises a switching element having a rise time t.sub.on and a fall time t.sub.off ; a control device for controlling the switching operation of the switching element; a transformer having a primary winding and a secondary winding, the primary winding being connected to a DC power source through the switching element, and having an open inductance L.sub.M ; an inductance coil having an inductance L connected to the secondary winding of the transformer; and a rectifying device for rectifying the output from the secondary winding of the transformer; assuming that the voltage applied to the primary winding of the transformer is E, the load current flowing through the transformer is I.sub.D, and the sum of the stray capacitance of the switching element and the distributed capacity of the windings of the transformer is C1, the following relational expressions being established:L>(E/I.sub.D)T.sub.onandL.sub.M >t.sub.off.sup.2 /.pi..sup.

Abstract: According to the present invention, a demolition agent for demolishing brittle materials is provided which comprises 30 to 90 parts by weight of a soft-burned quick lime powder having a crystal size of less than 10 microns and a specific surface area of 1,000 to 5,000 cm.sup.2 /g (Blaine) and 10 to 70 parts by weight of a hydraulic material, and further including, relative to 100 parts by weight of the mixture of the soft-burned quick lime and the hydraulic material, 0.5 to 15 parts by weight of a hydration retarder and 0.1 to 5 parts by weight of a water-reducing agent.
