Title: Informing device and portable communication equipment using the device
Inventor: HAMAGUCHI SHUNEI
IPC: H04M1/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To miniaturize a device by selecting whether to impress a signal including a specific frequency generated by a signal generation circuit to the coil of an oscillation generator or to impress the signal to the coil of the oscilla tion generator through a filter circuit interrupting a specific frequency generated by the signal generation circuit so as to transmit call-incoming information and a speech signal. SOLUTION: A portable telephone equipment main body 1 intermittently receives radio waves sent from a base station and detects a call to its own station by an incoming call detecting circuit 12 from a control signal signal- processed by a signal processing circuit 8. Depending on the setting state of a call setting means 13, a control circuit 11 switches a switch means 14 to give information on call incoming by oscillation or sound. When a user carries out off-hook for speech based on this information, the circuit 11 connects the means 14 to a terminal (a). Concerning speech outputted from a speech processing circuit 7, a signal near an information frequency f1 is interrupted through a filter 10 to receive only speech on an opposite side.

IPC: H04N19/50
Filed: 1984-04-04
Abstract: PURPOSE:To obtain high compressive capacity using an inexpensive device by normalizing the level of a picture signal, and making encoding based on the Markov model for the picture signal after normalizing by relative level differences. CONSTITUTION:It is assumed that the signal level of a picture to be encoded has a distribution of A in the figure. Picture signals in a memory 9 are read out once in a threshold value making device 10 and the distribution of signal levels is measured, and the smallest signal level whose cumulative distribution exceeds n/16 (n=1-15) is made to the n-th threshold value respectively. The threshold value information is encoded by an encoder 12 to binary numbers of 8 bits respectively and encoded by an OR circuit 8. Then picture signals read out are normalized by a normalizing device 11 as A in the figure according to the above-mentioned threshold value information, and the signals are encoded as in conventional ways. Finally, additional bits that show which the level of the original picture signal corresponding to the normalizing signal level in each element are encoded by an encoder 13. Thus, as normalized picture signals can be encoded by the convertional quantity of code data after normalization, its high compressive capacity can be obtained.

Title: Cathode-ray tube prepared by use of single lab6 crystal
Inventor: MOTOYAMA KAKUKI
IPC: H01J29/48
Filed: 1981-05-08
Abstract: PURPOSE:To enable a number of electron beams to be obtained with a single cathode, increase the luminance of the electron beams, and realize the stabilization over a long period of the luminance of the electron beams by using a single LaB6 crystal as a cathode. CONSTITUTION:An electron gun 5 consisting of a monocrystalline LaB6 cathode 2, a Wehnelt electrode 3, an accelerating electrode 4 and the like is installed inside a neck 1a of a glass bulb 1. Since three electron beams discharged simultaneously from the electron gun 5 are deflected and controlled by means of a deflecting coil 7, the glass bulb 1 provided with the electron gun 5 can accomplish the same function as a usual three-electron-gun-type Braun color tube. Here, since a single LaB6 crystal is used as the cathode 2, the luminance of the electron beams can be much more widely (above 5 times) increased compared to a conventional cathode. In addition, since only one cathode 2 is used, the structure of the electron gun part can be simplified and reduced in size.

Title: Measuring method of interference
Inventor: KATANO MITSUSHI
IPC: G01M11/00
Filed: 1984-04-06
Abstract: PURPOSE:To measure wave front aberration with high precision by employing such a coherent light source that a supply current and projection light vary in specific relation, and controlling the current and modulating the phase of coherent light. CONSTITUTION:Light projected from a semiconductor laser as the coherent light source 1 is split into two by a beam splitter 3, and one beam is passed through an optical path 11 to be detected to illuminate a body 5 to be measured. Light reflected by this body 5 to be measured and the other split light beam as reference light are guided to an interference pattern generating optical path 13 and interference fringes produced by the two pieces of luminous flux are obtained as two-dimensional information by a photodetecting element 9. In general, the semiconductor laser has a region where the wavelength lambda0 varies linearly with the current I, so that current supplied to the semiconductor laser is controlled in this region to cause variation in optical laser wavelength, modulating phase of interference light. Then, phases of respective addresses of the element 9 where the interference fringes are projected and image-formed are detected. This constitution, therefore, eliminates the need to provided a phase-modulating means on the optical path and facilitates the phase modulation, thereby measuring the wave front aberration with high presision.

Filed: 1989-03-22
Abstract: PURPOSE:To analyze an asphaltene component quickly and handily by comparing a light scattering level in a sol between an asphaltene suspension wherein a low quality fuel oil is diluted and dissolved by n-hepthane and a complete dissolved liquid diluted at the same factor by toluene. CONSTITUTION:A low quality fuel oil of a sample tank 4 is sucked with a pump 5 and diluted and dissolved in a stirring/dissolution tank 7 about 100 times. On the other hand, n-hepthane is injected into a discharge system to be diluted about 2,000 times by capacity and a malten component alone is dissolved to make an asphaltene sol suspension. Absorbance, transmission light absorptivity and turbidity of the suspension are measured with a measuring section. Toluene is injected to other systems and diluted to the same factor as with n-hepthane to dissolve malten and asphaltene completely. The liquid thus obtained is introduced to a measuring section 2 to measure an absorbance, transmission light absorptivity and turbidity thereof. A computation output section 3 estimates an asphaltene component from a difference between measured values. With such an arrangement, an analysis value is found quickly.

Filed: 1981-05-08
Abstract: PURPOSE:To increase the capacity and the output of a pasted electrode for a  lead acid battery by producing a porous body, which accelerates the discharge  reaction during the high-rate discharge, over the surface of an active material by drying a paste packed into a supporter in an atmosphere containing more carbon dioxide gas than the natural atmosphere. CONSTITUTION:A positive plate is manufactured by packing a paste into an expanded metal grid having a width of 135x, a height of 110x and a thickness of 1.4x. After the packing of the paste into the grids, the plates are dried in 15 different atmospheres with varied carbon dioxide gas concentrations, from 1% to 95% and batteries are assembled by use of the above plates. In the figure, the relationship between the carbon dioxide gas concentrations of the atmospheres in which the above plates are dried, and the discharge duration time of the batteries is indicated. As is seen in the figure, discharge duration time is remarkably short at a carbon dioxide concentration of less than 10%, and it becomes short at a carbon dioxide gas concentration of above 80%. Consequently, it was found that the carbon dioxide gas concentration of the atmosphere during the drying should be above 10% and less than 80%.
