Abstract: PURPOSE:To dissolve inconvenience of complicated code management on the side of each broadcasting station or acknowledgement of a code change of a VTR user by changing a reservation data based on information as to a change in the broadcast ing time for a program to be sent from the broadcasting station by superimposing. CONSTITUTION:A video signal in an area where a superimposing display is performed at the time of changing the broadcasting time is taken out by time sharing by a signal separating part 2, and the taken out video signal is digitized and stored in a post stage picture memory 3. The picture data stored in the picture memory 3 is inputted to a post stage acknowledging part 4 to acknowledge characters of the infor mation of the change, and this is transferred as it is coded with a code to a reservation information changing part 5. In the reservation information changing part 5, the infor mation of the change is added to the reservation information stored in a reservation information memory 6. That is, the time as shown in the information of the change is added to the previously set video recording starting time and finishing time respec tively, and as a result of this addition, the reservation information of the reservation information memory 6 is renewed. By this method, it is not necessary to perform extra work for program code management, etc., and a sudden change in the program broadcasting time can flexibly be dealt with.

IPC: F25B13/00
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner where stable reheating dry operation with improved dehumidification performance without being influenced by outdoor environment is possible. SOLUTION: The flow going to an outdoor heat exchanger 15 from a second indoor heat exchanger 22 is returned to a compressor 3 through a bypass passage 43 at the time of dehumidifying operation of heating cycle where the first indoor heat exchanger 21 functions as a condenser and the second indoor heat exchanger 22 does as an evaporator, by closing a first motor-driven expansion valve 39. Since a refrigerant does not pass through the outdoor heat exchanger 15, the condition lower than the evaporation temperature in the second indoor heat exchanger 22 is maintained practically without being influenced by the environmental change of ambient temperature, etc., since the refrigerant does not pass the outdoor heat exchanger 15. As a result, this can perform reheating dry operation where favorable reheating capacity is maintained.

Abstract: PURPOSE:To secure output amplitude equivalent to at least hystereis width by increasing output load capacitance by attaching a hysteresis on at least one inverter circuit in a ring oscillator circuit. CONSTITUTION:Each of the inverter circuits 1(1)-1(n) maintains the output of a preceding state until the output voltage of a preceding state inverter circuit exceeds a trip point by its own input hysteresis characteristic.

Abstract: PURPOSE:To attain a connection request to be connected to a terminal equipment whose accommodation is replaced by deciding an exchange station being an accommodation replacement destination in advance on the occurrence of a fault in an exchange station, storing a table with the destination station to each exchange station and selecting an exchange station in a predetermined sequence based on destination subscriber address information in the case of making a call. CONSTITUTION:An exchange station being an accommodation replacement destination is decided sequentially as to information of an accommodation replacement destination (station number) with respect to destination subscriber addresses and registered in a station number dependent object station number table (retrieval table) in the order of priority. For example, the 1st priority accommodation replacement destination of subscriber terminals accommodated in an exchange station 2 is decided to be an exchange station 3. For example, when a subscriber terminal equipment 10 makes a call to a subscriber terminal equipment 20, an exchange station 1 sends a connection request to the exchange station 2 based on destination subscriber address information of the subscriber terminal equipment 20 at first. However, the exchange station 2 cannot be connected due to a fault. Then the retrieval table stored in itself is referenced and a connection request is sent to the an accommodation replacement destination 3 of the 1st priority and then the connection is completed.

Abstract: PURPOSE:To improve safety of a heat-sensitive print recording medium by using color tone and a pattern of a pattern-like colored mark hidden under a metal thin film for judgement of the truth and to improve furthermore safety by assembling not only the colored mark but a background color layer. CONSTITUTION:In a heat-sensitive print-type recording medium wherein a background color layer 2 and a metal thin layer 4 are formed on the, whole face of one of the surface of a base material 1, a colored mark 7 is provided between the background color layer 2 and the metal thin layer 4. This colored mark 7 is formed by a specified pattern in such a way that it is piled up on a part of the background color layer 2. Under this condition as it is, the colored mark 7 is not visible because of obstruction of the metal thin layer 4 but when the metal thin layer 4 is melted and destroyed by a heating means being similar to the print recording of a visible information, it becomes visible through this destroyed part to constitute a security information.

Title: Surface potential detector
Inventor: MURATA MITSUHIRO
IPC: G01R29/24
Filed: 1982-08-18
Abstract: PURPOSE:To eliminate possible leakage and improve the detection sensitivity in surface potential of a photosensitive body for an electrophotographic copying equipment by applying a line of electric force to a collector electrode through a dielectric plate after the dielectric plate with the collector electrode formed thereon is mounted on the opening of a case so as to position the collector electrode within the case. CONSTITUTION:When a high voltage is applied to the surface to be inspected, a line of electric force from the surface of a high potential is admitted to a collector electrode 3 through a dielectric plate 2 and a charge is stored between the collector electrode 3 acting as one variable condensor electrode and a condenser electrode 7. When a piezo- electric tuning fork 4 is driven to vary the distance between the electrodes 3 and 7 by vibrating the condenser electrode 7, an electric charging or discharging is done with the variation in the capacity and a corresponding electrical signal is applied to an FET and a detection voltage is taken out of the FET through an amplifier. With such a closed arrangement, this prevents the infiltration of a toner or the like into the case 1 eliminating possible leakage or lower sensitivity when this equiment is used for non- destructive measurement of surface potential of an electrostatic drum in a copying machine.

Filed: 1981-09-14
Abstract: PURPOSE:To reduce the noise which is caused during the transmission, by dividing a data of paralleled N bits and transmitting these data in parallel by every N/n bits. CONSTITUTION:The data of 16 bits is divided into 4 groups each of 4 bits respectively, and bits 0-3 are first transmitted when the output control signal is supplied. This output control signal passes through a delaying element 18 and then performs a control to transmit bits 4-7, bits 8-11 and bits 12-15 respectively. Thus the paralleled signals of 16 bits are divided by every 4 bits and then transmitted successively. This reduces the noise produced from a transmission line.
