Title: Channel selection data preset device for voltage synthesizer tuner
Inventor: ITAGAKI YOSHIHIRO
IPC: H03J7/18
Filed: 1986-05-20
Abstract: PURPOSE:To decrease the prescribed time for a channel selection data preset by using the 1st BPF so as to detect that an IF signal approaches a prescribed frequency. CONSTITUTION:A computer 30 changes a duty ratio of a PWM wave inputted to an oscillator 14 as a tuning signal via an LPF 26 quickly. When the oscillating frequency of the oscillator 14 approaches the frequency at the time of reception of a broadcast of a channel, the IP signal passes through the 1st BPF 36 and the 1st level detection circuit 40 detects it. The computer 30 increased the value of the PWM wave by a prescribed value by using a detection signal from the circuit 40 to vary the duty ratio change of the PWM wave from a PWM oscillator 44 at a low speed. When the oscillating frequency of the oscillator 14 reaches the frequency at the reception of broadcast of the channel 1, the IF signal passes through the 2nd BPF 38 and it is detected by the 2nd level detection circuit 42. The computer 30 recognizes the oscillating state of the oscillator 14 at the oscillating frequency at the reception of the channel 1 by using the detection signal.

IPC: G02F1/13
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to be adapted to an optical use different in polarization state by forming electrodes into multiple ring shape and rendering a liquid crystal in a twisted state. SOLUTION: The electrode 11 is formed into a circle, and electrodes 12, 13 are formed into ring shape symmetric and concentric to the center of the electrode 11, at least one of the electrodes is formed into a multiple ring shape. In order to form these electrodes of a liquid crystal lens to satisfy a function as a Fresnel lens, the repeating period of the electrodes is decreased from the center to the periphery. Orientation of the liquid crystal 15 is controlled by an oriented film. As for the liquid crystal 15, a normal nematic liquid crystal is used. The nematic liquid crystal includes a liquid crystal which contains an optically active material and shows a naturally twisted state.  Since the liquid crystal is twisted in this liquid crystal lens, the liquid crystal acts as a lens for both of right-hand circular polarized light and left-hand circular polarized light, and thereby, it also acts as a same lens for incident light having linear polarized light in different direction.

IPC: H01Q1/10
Filed: 1986-05-20
Abstract: PURPOSE:To enable a rod antenna length to be adjusted automatically during stopping and traveling, by providing a comparator which outputs a signal when the number of rotating pulses stored at a preset circuit coincide with those counted by a counter.

Title: Am radio receiver
Inventor: TOKUYAMA TAKASHI
IPC: H04B1/12
Filed: 1992-05-08
Abstract: PURPOSE:To receive AM radio waves with high sound quality free from interference noises. CONSTITUTION:When frequency interval between adjacent channels in AM broadcasting is DELTAF, an A/D converter 17 samples an output from an AM detector 16 at fs (>=DELTAF) and A/D converts the sampled data and a digital FIR filter 18 filters the data outputted from the A/D converter 17 to cut out a band component more than a prescribed frequency including noises between the adjacent channels. Although noises can be removed by the processing, a signal component in the band is also removed. Thereby the sampling rate of the output data from the filter 18 is reduced to 1/2, and while interpolating one digital data between digital data whose sampling rate is turned to 1/2, the digital data are converted into an analog signal by a D/A converter 20. Consequently the signal component cut in the band higher than the prescribed frequency can be apparently formed and added and AM radio waves free from interference noises and having high sound quality can be received.

Title: Electroluminescent element and manufacture thereof
Inventor: FRIEND RICHARD H
IPC: H01L33/26
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide an electroluminescent element which has a wide surface area and whose electric power consumption is low by forming a poly phenylene vinylene PPV film with the thickness within a specified μm range on the surface of a first charge injection contact layer. SOLUTION: A first electric charge injection contact layer 2 is formed on the upper face of a glass substrate such as about 1mm silicon or borosilicate glass 1 substrate. This electric charge injection contact layer 2 is formed by thermal evaporation of aluminum through a shadow mask and then a thin surface oxidation layer 3 is formed. Next, a polymer solution is applied to the whole surface area of a joining substrate and while keeping the upper face in a horizontal state, the substrate is rotated at a specified rotation speed on an axis and the resultant substrate is thermally treated in an oven to convert the polymer precursor into PPV. The obtained PPV film 4 has 100-300nm thickness. After that, a second electric charge injection contact layer 5 is formed on the PPV film 4 by evaporation and an electric charge injection contact layer with 20-30nm thickness is thus obtained.  Consequently, an element with wide surface area and low electric power consumption is obtained.

Abstract: PURPOSE:To enable to control etching time as well as to contrive microscopic formation of a pattern by a method wherein, when an Al wiring pattern is formed on an insulating layer, the Al layer which was exposed by performing a plasma etching is removed after the oxide layer on the surface of the Al layer has been removed by performing an ion etching.

Abstract: PURPOSE:To discharge a waste photographic processing solution to rivers by electrolytically treating an aqueous solution containing a thiosulfate ion in a three-dimensional electrode electrolytic cell and oxidizing the thiosulfate ion to a high order sulfur oxide ion. CONSTITUTION:An aqueous thiosulfuric acid solution is supplied to a three-dimensional electrode-electrolytic cell 2 to be subjected to oxidation treatment. The flow rate of the aqueous thiosulfuric acid solution supplied to the electrolytic cell 2 may be to prescribed so that the aqueous solution efficiently comes into contact with the surfaces of electrodes to oxidize a thiosulfate ion and, when the aqueous solution flows in a perfectly lamina state, the movement of the aqueous solution to a lateral direction is reduced and the contact with the electrodes, dielectrics and the surfaces of fine particles is reduced and, therefore, a turblent flow state is pref. formed. Further, the electrode potential at this time is pref. set to -0.1-1.0vs. SHE in anode potential. The thiosulfate ion is almost selectively oxidized to a polythosulfate ion within this potential range and can be subjected to oxidative decomposition without precipitating sulfur. By this method, a waste photographic processing solution can be discharged to rivers.

Abstract: PROBLEM TO BE SOLVED: To obtain an image of high quality without having gloss unevenness by superimposing a toner image carrier on a recording medium and then, reversing the curvature directions of the toner image carrier and the recording medium once, before heating/pressing are completed. SOLUTION: An intermediate transfer body 50 is temporarily pressed on a pressure roll 3 by a curvature reverse roll 8, before the transfer body 50 enters into a nip part N formed between a heating roll 2 and the pressure roll 3. Thus, a toner image on the intermediate transfer body 50 is pushed, that is, pressed against the pressure roll 3 with a paper sheet 60 interposed. Consequently, a curvature reverse part C whose curvature is opposite to that of the nip part N is formed. The width of the curvature reverse part C is adjusted by the change of the height of the curvature roll 8. Then, the intermediate trnasfer body 50 and the paper 60 are moved between the heating roll 2 and the pressure roll 3, so that the toner image is further pressed strongly and heated.  Toner heated up to a melting temp. or higher is softened/melted to infiltrate the paper 60 and then, solidified, that is, transferring/fixing is attained.
