摘要： PROBLEM TO BE SOLVED: To efficiently print on a designated paper by storing a paper size at a previous print time, stopping printing and requiring confirmation of the paper size when a paper of a different size from that of the previous print time is designated, and continuing the printing when the size is the same as the previous size. SOLUTION: When print data to be processed is ready to be transmitted after a precedent page is completely printed, a control computer 72 processes to receive print data of the present page, and judges whether a paper size designated this time is the same as that of the previous page. When the size is the same, an image development process is carried out and then the size of the printed paper is stored as a previous size. On the other hand, if the size is judged to be different from the previous size, the printing is stopped once, and an exchange of papers is requested to an operator. The operator instructs to resume the printing as it is after confirming the paper and finding no necessity for exchange, so that the printing is continued.

摘要： PROBLEM TO BE SOLVED: To obtain a floated broad-band signal on the non-floating side. SOLUTION: Multiplication circuits 20 and 60 are arranged both on the left floating side and on the right non-floating side of insulation transformers 11 and 12 and a high frequency sinusoidal signal is supplied from an oscillator 18. The multiplication 20 performs a multiplication between an input signal applied to input terminals 1a and 1b and a high frequency sinusoidal signal 18 applied to terminals 3a and 3b. The results are multiplied by the high frequency sinusoidal signal 18 at the multiplication circuit 60 to obtain an input signal restored to output terminals 2a and 2b through low pass filters 67 and 68. Light or a radio wave can be used in place of the insulation transformers 11 and 12. Two sets of circuits as illustrated are used and the phase difference of the high frequency sinusoidal signal 18 between the two systems is set to 90 deg. to add outputs of the two multiplication circuits 60. This can eliminate low pass filters 67 and 68.

摘要： PROBLEM TO BE SOLVED: To obtain a wet plate making machine capable of preventing the danger of the addition of liquid toner, even if a liquid level in a developer tank reaches an upper limit. SOLUTION: An wet plate making machine is provided with concentration detecting units TS1 and TS2 and a controller CPU to which signals outputted from liquid quantity detecting switches LS1 and LS2 are inputted and which processes the signals inputted from the switches LS1 and LS2 , to control a developer circulating pump 79A, a developer supplying pump 79 and a toner supplying pump 81. This controller CPU checks whether liquid quantity signals from the liquid quantity detecting switches LS1 and LS2 are within proper ranges or not. When the liquid quantity signals are under the proper ranges, a fresh developer is replenished to the developer tank 77 from a developer bottle EB through the developer supplying pump 79 and then, toner concentration processing is attained. When the liquid quantity signals are over the proper ranges, an 'overflow alarm' is issued.

摘要： PROBLEM TO BE SOLVED: To deal with the congestion of queues by exchanging queue priority by storing the queue read priority, which is different from a packet data memory circuit having plural queues, one by one or as a data base, generating a queue number and selecting a priority number. SOLUTION: N pieces of queue number generating circuits 3 (3-1 to 3-n) respectively store different queue read priority #1...#n. The queue number selecting circuit 3 selected by an enable signal from a selector circuit 4 selects the queue of the highest queue read priority, for which the number of stored packet data in queue information is not '0'. and outputs it to a memory read managing circuit 2 according to the priority. According to a timing signal from the outside, the memory read managing circuit 2 updates the queue information to the selector circuit 4 and the queue number generating circuits 3 and controls the queue read side of a packet data memory circuit 1.

摘要： PROBLEM TO BE SOLVED: To prevent fluttering and flaw of waveform in character indication by controlling to indicate observed waveform in an indication term and charac ter indication signal in the other term. SOLUTION: An indication control circuit 20 controls to let a waveform indication signal 33 pass in the existing term of sweep term signal 51 as a term indicating observed waveform and let a character indication signal 34 pass for indication in the term when the sweep term signal 51 does not exist. That is, the indication control circuit 20 having received a character indication switch signal 35 and a sweep term signal 51 outputs a switch control signal 55 by the direction of an indication control signal 52. The terminals (a) and (b) of turnover switch 14 are impressed a waveform indication signal 33 and a character indication signal 34, switched by a switch control signal 55 and indication signal 37 is obtained. The indication signal 37 is amplified with a vertical amplifier 15, and the amplified indication signal 38 biases the vertical axis of CRT. By this, flaw of observed waveform does not occur and fluttering disappears.

摘要： PROBLEM TO BE SOLVED: To physically prevent the reverse voltage load due to the wrong insertion of dry battery without using a diode by providing a wall of a groove, which is provided in a battery holding support so as to house a battery current-carrying electrode, with a projecting wall having a step on a positive electrode side, and engaging this projection with a negative electrode end of a battery for fixation when the battery is reversely inserted, and forming an insulating space distance between it and a current-carrying electrode of the positive electrode. SOLUTION: An upper and a lower inner wall of a dry battery pack, attachable and detachable, for a cellular telephone is provided with a groove for housing a battery current-carrying electrode. A common type 5-6 to negative and positive electrodes, a negative electrode type 5-7, and a positive electrode type 5-8, which are formed of a piano wire or a phosphor bronze spring wire, are inserted into the groove for fixation. A space between a projection 5-1 with step and the common type 5-6 for negative and positive electrode and the type 5-8 for positive electrode are formed at a nearly half of a projection dimension (h) of a positive electrode projection 5-4 of a dry battery, and in the case where the dry batter is normally inserted, the positive electrode of the battery and the electrode of positive electrode make contact with each other under the predetermined spring pressure. In the case where the dry battery is reversely inserted, a space between the negative electrode of the battery and the electrode of the positive electrode is physically held.
