IPC: H04N5/445
Filed: 1992-01-24
Abstract: PURPOSE:To easily detect the channel selected before by providing a channel transition storage means and displaying present channel information on a picture together with past channel information of channels selected before at the time of selecting operation. CONSTITUTION:When an operation signal is inputted to a CPU 9 and an execution function discriminating means 9a judges that this signal is channel selecting data, a channel switching signal is outputted from the CPU 9 to a tuner to switch the broadcast channel. Simultaneously, the selected channel from a channel transition storage means 9 is stored, and a character display instruction is outputted to a character selecting means 9d. When a channel key is operated to switch the channel to another channel, the CPU 9 displays the channel of the preceding picture stored in a storage means 9b and the newly selected present channel. Present channel information is stored in the storage means 9b.

Filed: 1990-02-13
Abstract: PURPOSE:To multiplex a line data onto a optional position by inverting an even numbered bit only when the line data is inserted to a position where a line control data is multiplexed. CONSTITUTION:A data transmission timing generating circuit 10 of a (n+1)th line reads information to which location a data of the (n+1)th line is to be multiplexed based on a multiplex timing signal 3 and an allocation position designation signal 4. Then the circuit 10 sends a data transmission timing signal 5 to send a data to a multiplex circuit 9 to a data transmission circuit 8 and a line data 2 is outputted from the data transmission circuit 8. When the position where the line data 2 is to be multiplexed is designated to the position where the line control data is substantially to be inserted, the data transmission timing generating circuit 10 outputs an even numbered bit inversion instruction 6 to the even numbered bit inverting circuit 7 and the even numbered bit inverting circuit 7 inverts even numbered bits of the line data. Thus, the line data is multiplexed onto an optional position.

Title: High-temperature-fluid heat-mixer
Inventor: MORI YOSHIMICHI
IPC: B01F15/06
Filed: 1978-03-27
Abstract: PURPOSE:To reduce pressure loss, by operation heat mixing by means of heat pipes provided in a high-temperature fluid passage. CONSTITUTION:A plurality of heat pipes are provided in duct 1 immediately preceding reactor 4 and at right angles to the direction of gas flow and in parallel to one another at equal intervals. The above-described heat pipe groups are arranged in stages in the direction of gas flow and heat pipe 5 belonging to each group is placed in the vertical or the horizontal direction for each stage, since gas temperature differences in duct 1 are produced in the vertical or the horizontal direction. Consequently, heat is effectively transferred from the high-temperature region to the low- temperature region, and the temperatures distribution of gas drawn into reactor 4 becomes nearly uniform. As a result, a high denitrification rate is obtained, and the pressure loss is small compared with the case of mechanical gas mixing.

Title: Property evaluating method for cation exchange resin and water treatment system control method using it
Inventor: MARUTANI HARUKO
IPC: C02F1/42
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To evaluate the performance of a cation exchange resin and judge the replacement timing by adsorbing copper ions and/or iron ions to a cation exchange resin, putting it in touch with a hydrazine aqueous solution to generate accelerative deterioration, putting an eluate in contact with it, and measuring the amount of polystylene sulfonic acid eluded from the resin at this time. SOLUTION: Copper ions or iron ions are adsorbed to an ion exchange resin. The ion absorption resin is contacted with a hydrazine water solution so that cation exchange resin is deteriorated forcedly. The copper ions contacted and adsorbed are segregated by a water solution of hydrochloric acid. The resin is immersed in a water solution containing ammonia and hydrazine, followed by shaking, and the performance of the resin is evaluated using as index the amount of polystylene sulfonic acid in the eluate. The index for evaluation of the resin performance should be a PSS whose molecular weight in the eluded polystyrene sulfonic acid is over 1600, preferably over 5000. The replacement timing of resin is decided on the basis of the value obtained.

Title: Avalanche photodiode
Inventor: WATANABE ISAO
IPC: H01L31/107
Filed: 1990-02-14
Abstract: PURPOSE:To obtain an avalanche photodiode of low noise and very high speed, by constituting superlattice of a barrier layer having resonance tunnel characteristics of short period superlattice and a well layer. CONSTITUTION:The title diode is constituted of a barrier layer 21 having resonance tunnel characteristics of short period superlattice and a well layer 22. A region (resonance tunnel barrier layer 21) where electrons 26 turn to ions and a region (well layer 22) where electrons 26 are accelerated are isolated. Since the well layer 22 is a comparatively thick layer where the quantum level is not formed, the increase of band gap corresponding to the energy amount of quantum level is not generated, so that the increase of ionization threshold energy and the decrease of ionization ratio are not caused. Further, since the resonance tunnel barrier 21 is used for the barrier layer, the electrons 26 can easily escape from the well layer 22 through electron conduction of a miniband, and the reduction of noise caused by random emission of electrons can be realized.

Abstract: PURPOSE:To measure characteristic values at a time and to evade misdecision making due to a fault of a test circuit by providing an inverter, a dissidence circuit, and a fault detector for the dissidence circuit which have the same manufacture conditions with an internal logic circuit. CONSTITUTION:An input voltage (Vmin) is raised and then the signal outputted from a TP 117 varies from 'L' to 'H' at a certain input voltage value. A TIP signal varies from 'H' to 'L' through the operation of the inverter which has maximum Vth among plural inverters 13. Variance in Vth among the inverters 134 is shown with the 'H' signal as shown in a figure, and consequently it can be judged whether or not a circuit is normal or defective. If, however, there is a fault between a multi-input AND circuit 14 and a multi-input NOR circuit 15 and the outputs of those circuits 14 and 15 are both 'H', the TP1 is 'H'. At this time, an AND circuit 18 and its output pin 19 are provided so as to monitor the abnormality of the dissidence circuit.

Abstract: PURPOSE:To provide the adjusting method for the beam generation unit which can adjust the interval between a semiconductor laser and a beam shaping lens in the direction of the optical axis with an adjustment error smaller than the depth of focus of the beam shaping lens constituting the beam generation unit.
