IPC: H04L1/00
Filed: 1993-12-17
Abstract: PURPOSE:To improve transmission characteristic by referring to a generating model of 1 or 0 in the remarked bit of information source encoder output. CONSTITUTION:A logarithmic branchmetric(brm) Mc corresponding to the state transition of trellis of a code is calcualted by a computer 21 on one side, and the logarithmic brmMs corresponding to the state transition of a Markov information source.is calculated by a computer 22 on the other side. Thence, the output of both computers 21, 22 are inputted to an ACS 23, and the brmM on expanded trellis is supplied in the sum M of them. After error correction encoding is applied to it, it is stored in a pass memory 24. In such a case, a Markov model is given as a reference model. In other words, decoding by viterbi algorithm is performed on the trellis constituted of an extension state S=ScXSc generated from the direct product of (n) states Sc which comprise the trellis of the code and (m) states Ss of the Markov information source. Also, the logarithmic brmM for the transition from a state SciSsk to a state ScjSsl is given as M= Mcij+2 3s LogePkl, where, Pkl is transition probability.

Title: Facsimile machine provided with charging device
Inventor: WATAI KOKI
IPC: H04M11/00
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To enable a facsimile machine provided with charging device to limit charging based on a more accurate predicted communication charge, and also to avoid occurrence of a case where the machine is disabled from charging a user due to insufficient remaining money left. SOLUTION: This facsimile machine fetches information on remaining money from a charging device (S1), stores a one-page original (S2), and calculates the size of the stored image (S3). Then the machine calculates the communication charge by predicting the communication time from the size (S4), and when a file to be string-transmitted exists in the files waiting for transmission (S5), the machine predicts the communication charge from the total size of the files to be string-transmitted (S7) and the communication charge of the files waiting for transmission which has the same ID as that of files other than the files to be string-transmitted (S6) and adds the predicted charges to the charge calculated in S4 (S8).  Then the machine compares the calculated predicted communication charge with the remaining money previously taken out (S9), and when the remaining money is larger than the predicted charge, the machine stores the next-page original. When the remaining money is smaller than the predicted charge, the machine terminates the storage, even when the transmitted original is left.

Title: Composite tone output device
Inventor: KEZUKA HIROKO
IPC: G10L13/02
Filed: 1988-12-20
Abstract: PURPOSE:To improve intelligibility by controlling the time for outputting a syllable by a rule of a rhythm of the Japanese language. CONSTITUTION:The utterance of an outputted sentence (a) is delimited at every sentence clause by an interval (b), and in that case, a long sentence clause is further divided into every word. Subsequently, a prescribed time of a quadruple time portion is allocated to a time interval of one sentence clause, and its time is divided into the number of syllables. In this case, when the number of syllables is <=4, a prescribed time is divided into four equal parts, its equally divided time is allocated to one sentence clause, and the remaining time becomes silent. In such a way, by outputting a composite tone, the Japanese language having a rhythm being similar to nature is outputted.

Title: Temperature displaying apparatus
Inventor: ADACHI HIDEYUKI
IPC: G01K11/00
Filed: 1988-12-19
Abstract: PURPOSE:To simplify the constitution and to make the configuration compact by using a shape memory resin or a shape memory rubber wherein transistion temperature is present and deformation occurs at the transition temperature as a temperature sensitive element. CONSTITUTION:A display sheet 6 as a temperature sensitive element is provided at the periphery of the opening of a recess part 5 which is formed at the side surface of a main part 3 of an operating part so as to cover the opening. The sheet 6 is formed of a shape memory resin. Before disinfection of a treating tool for an endoscope, the sheet 6 is under normal temperature. The temperature is lower than the transition temperature of glass. The sheet has the approximately flat patter which is not protruding outward by the heating and deformation and the cooling and fixing operation which have been conducted beforehand. This pattern displays the state before the disinfection. When the treating tool for the endoscope is heated and disinfected in an autoclave, the temperature at that time reaches about 120 deg.C. The temperature of the sheet 6 exceeds the transition temperature of the glass and the sheet becomes soft. The sheet is deformed and made to protrude outward by receiving the energizing force of a spring 8 of a compressing coil. Therefore, whether the disinfection is finished or not can be judged based on the protruding deformation of the sheet 6.

Title: Bath tub having built-in latent heat storage material
Inventor: HARADA YOSHITAKA
IPC: A47K3/02
Filed: 1991-09-27
Abstract: PURPOSE:To reduce follow-up boiling time and the amount of added hot water by making the hot water of a bath tub hard to chill. CONSTITUTION:A bath tub 1 is made to incorporate a latent heat storage material 2 with a melting point thereof near the temperature of a hot water preferred among ordinary people and a heat insulating material 3 outside it. The amount of the latent heat storage material 2 is set by considering desired holding time and a heat radiation loss. The hot water 2 is fed with the temperature thereof enough to cause a phase chance. The hot water is supplied into the bath tub 1 with the temperature thereof. The latent heat storage material 2 stores latent heat and the temperature of a hot water lowers down near the melting point to achieve a comfortable temperature of the hot water. Thereafter, when the temperature of the hot water tends to lower with the external radiation of heat, conversely, heat is supplied to the hot water from the latent heat storage material 2 to maintain the temperature of the hot water corresponding to the heat stored. Thus, the follow-up boiling time is reduced conveniently. This also can reduce the amount of adding hot water to be added in the bath tub permitting no follow-up boiling thereby resulting in decrease in the amount of the hot water chilled to be discarded. The conservation of a water source achieves a saving of energy when the heating value of the hot water to be discarded in the past is larger than the amount of heat stored.
