Title: Solid-state image sensor
Inventor: YAMAKAWA SATOSHI
IPC: H04N5/335
Filed: 1987-06-16
Abstract: PURPOSE:To suppress a smear generated by the fact that generated photons are flown to a vertical CCD by completely isolating a charge transfer unit from a photodiode by a trench structure. CONSTITUTION:A photoresist 2 is patterned between a photodiode and a vertical CCD, and silicon-etched to form a trench. Then, isolating P<+> type ions are implanted to a wall of trench side. Thereafter, a trench groove is buried with oxide 5. Subsequently, an epitaxial growth 6 of sufficient thickness to bury the insulator in the groove is performed. Then, a solid state image sensor is manufactured by a normal process. A smear which passes the lower section of a conventional isolating oxide film 8 can be suppressed by isolating a vertical CCD and a photodiode 10 by buried trench isolation. Since the width of a conventional isolation region is determined by the trench isolation, a solid state image sensor which has higher density than the conventional one can be obtained.

Title: Noise reduction device
Inventor: NAKAYAMA TADAYOSHI
IPC: H04N5/21
Filed: 1990-06-08
Abstract: PURPOSE:To change quantity of circulation continuously and smoothly by applying prescribed power processing to an output of an amplitude limit means limiting an amplitude being a difference between a delayed signal and an input signal, subtracting an output resulting from multiplying a prescribed coefficient with the processed signal from an output of the amplitude limit means and adding the input terminal to the output so as to output an output signal whose noise is reduced. CONSTITUTION:A difference between a delayed signal and an input signal is given to a limiter 34, in which the amplitude of an output signal (x) is limited in a range of +L - -L and a power arithmetic circuit 36 outputs signal of ¦x¦<n>.x with respect to the signal (x). A multiplier circuit 38 multiplies a coefficient (1-K) with an output of the power arithmetic circuit 36 and a subtractor 40 subtracts an output of the multiplier 38 from the output (x) of the limiter 34. Thus, an output (y) of the subtractor 40 is expressed as y={1-(1-K)¦x¦<n>}x. Thus, a cyclic coefficient is changed continuously in interlocking with the difference by setting a proper value of 2 or over to a value (n). Thus, the quantity of circulation changing continuously and smoothly is obtained with respect to a difference between picture element with high correlation.

Title: High atmospheric pressure transverse discharge excitation type metal vapor laser
Inventor: OUCHI KAZUMI
IPC: H01S3/038
Filed: 1987-06-17
Abstract: PURPOSE:To seal off an expensive Ne gas, etc., and use them repeatedly by adopting a transverse discharge excitation system in a metal vapor laser and shortening discharge length while combining pre-ionization. CONSTITUTION:The inside of a discharge tube 8 is brought to high atmospheric pressure, and a composite metal and a sublimating material are fed into the discharge tube by a supply means and sublimated. Voltage is applied to uniform field electrodes 2, 2 and pre-ionization pins 4, 4, and the ionization of a gas and the dissociation of metallic atoms and the sublimating material are conducted simultaneously, thus improving the efficiency of discharge. Since the inside of the discharge tube is brought to high atmospheric pressure, the gas can be circulated at high speed by turning a gas circulating fan 3, and the removal of a deteriorating gas in a discharge region and the deexcitation of atoms at a metastable level are promoted by utilizing the circulation at high speed of the gas, thus allowing highly repeated oscillation and high efficiency. The gas can be sealed off into the discharge tube, thus economizing expensive Ne gas, then reducing cost on operation.

Title: Production of fine a-type zeolite
Inventor: TOKINA NOBUO
IPC: C01B39/16
Filed: 1986-06-26
Abstract: PURPOSE:To suppress the formation of HS-type, etc., as a by-product and produce the titled crystals, by blending an aqueous solution of sodium silicate with an aqueous solution of sodium aluminate, reacting both solutions under condition of a high alkaline concentration at a low temperature till a specific time and aging and crystallizing the reaction product under condition of a low alkali concentration at a high temperature. CONSTITUTION:An aqueous solution of sodium silicate is blended with an aqueous solution of sodium aluminate at <=600 deg.C temperature to prepare a reaction slurry suspension containing >=12wt% alkali concentration expressed in terms of Na2O in the mother liquor and reaction is then carried out at <=60 deg.C temperature. When the crystallinity of zeolite in the reaction slurry suspension attains >=60% by an electron ray diffractometry and <=80% by the X-ray diffractometry, the alkali concentration in the reaction slurry is reduced to give 1-8wt% alkali concentration expressed in terms of Na2O in the mother liquor. The resultant reaction slurry suspension is then aged at 70-110 deg.C temperature to complete crystallization. Thereby the formation of HS-type, etc., as a by-product is suppressed to afford the aimed A-type zeolite having a small particle diameter.

Title: Radio equipment capable of controlling transmission output by adopting hot standby system
Inventor: KATASHIO KAZUYUKI
IPC: H04B1/74
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To simplify the circuit configuration and control algorithm of radio equipment by combining control systems into one system by only supplying the control signal of an output control board to the transmitter of an operated system. SOLUTION: An output control board controls the transmission outputs of transmitters 4 and 5 and a switch SW 7 only outputs the control signal of the board 7 to one of the transmitters 4 and 5 selected by means of a switching control board 9. When no control signal exists to the nonselected transmitter, the transmission output is set to the minimum value which is an initial value. Therefore, the mounting efficiency of radio equipment can be improved and the cost of the equipment can be reduced, because the two transmitters 4 and 5 are controlled by one output control board 6. In addition, the power consumption of the transmitters are reduced and the life time of the transmitters is prolonged, because the transmitters are always maintained at the minimum transmission output values when the transmitters are not selected.

Title: Kana/kanji conversion processor
Inventor: WATANABE SHUNSUKE
IPC: G06F17/22
Filed: 1987-06-17
Abstract: PURPOSE:To improve the operability of a KANA (Japanese syllabary)/KANJI (Chinese character) conversion processor by providing a memory means which stores the inscriptions corresponding to the input Japanese rendering of KANJI together with the information showing the validity/invalidity of conversion and then outputting the next conversion result in case the conversion result is invalidated by the information stored in said memory means. CONSTITUTION:A memory means 13 stores the inscription corresponding to the input Japanese rendering of KANJI together with the information showing the validity/invalidity of conversion when a character string inputted from an input part 1 is converted into a KANA-KANJI sentence. When a meaningless character string or such a character string that is never used hereafter is detected, this character string and its Japanese rendering of KANJI are stored together with the information that unables the regeneration of said character string. Furthermore, the candidate is not displayed in case the same Japanese rendering and its candidate are selected. Thus it is possible to avoid such a case where the candidate corresponding to an input character string is displayed in a meaningless form. Then the operability is improved for a KANA/KANJI conversion processor.
