Title: Tv broadcasting receiving system for frequency synthesizer tuning system
Inventor: SUGINO TENSHIYOU
IPC: H04N5/44
Filed: 1990-11-27
Abstract: PURPOSE:To shorten time for detecting an optimum point by storing a synchronizing deciding area, to which the detected optimum point belongs, in a storing means and starting the search operation of the optimum point from the stored synchronizing deciding area. CONSTITUTION:A CPU 5 stores the synchronizing judging area, to which the optimum point of a local oscillation frequency for correctly receiving the broadcasting of a desired station first detected belongs, in a second data storage part 8 and when tuning the original channel again, the former optimum point synchronizing judging area concerning the tuning channel is read out of the storage part 8. Then, a correspondent synchronizing deciding area is read out of a first data storage part 7 and it is set as the local oscillation frequency. Thus, time for detecting the optimum point can be considerably shortened, and time disturbing pictures on a TV screen can be shortened at the degree of almost not noticing it.

Title: Gain automatic changeover amplifier circuit
Inventor: TSUJIMURA YUJI
IPC: H03G3/30
Filed: 1987-12-23
Abstract: PURPOSE:To improve the response of gain changeover and to simplify the circuit constitution by applying gain changeover of an amplifier so as to decrease the gain of the amplifier when the input signal of the amplifier is larger and increase the gain of the amplifier when the input signal of the amplifier is smaller. CONSTITUTION:The circuit is provided with an amplifier 2 receiving a signal from a photoelectric conversion element 1 and amplifying the signal, a switching section 10 switching the gain of the amplifier 2 and a control section 8 giving a control signal of gain switching to the switching section 10 as the judgment reference for gain switching of the amplifier 2 from the output signal of the photoelectric conversion element 1. The gain of the amplifier 2 depends on the combined feedback resistance (r) between a resistance r2 of a feedback resistor R2 and a resistance r1 of a feedback resistor R1 and as the resistance of the feedback resistor is larger, the gain of the amplifier 2 is larger. Since the gain switching of the amplifier is judged by the hardware, the response is improved more than that of an amplifier circuit using the software for gain switching and the circuit constitution is simplified.

Title: Semiconductor memory
Inventor: TAKAGAKI KAZUO
IPC: G06F12/16
Filed: 1988-12-27
Abstract: PURPOSE:To prevent the copying operation errors by preparing a 1st memory part and a 2nd memory part which is used as a copy of the 1st memory part for the double writing purpose and adding a counter means to each memory part to record the normal writing frequency. CONSTITUTION:In a double writing state the same data is written into the semiconductor memories 2 and 3 by a semiconductor memory controller 1. Under such conditions, it is supposed that the memory 3 has a trouble and only the memory 2 is working. Then the memory 3 is restored and the power supplies of both memories are applied. Thus the contents of the save disks 21 and 31 are restored in both memories 2 and 3 respectively. In this case, a counter 20 has the larger value than a counter 30. Thus it is easily decided that the contents of the memory 3 are older than those of the memory 2 and the operating mistakes are prevented even in the case an operator has a mistake to perform a manual operation to copy the contents of the memory 3 to the memory 2.

Title: Fine powder of eggshell membrane and various functional agents utilizing oil absorptivity thereof
Inventor: KAWAGUCHI YOSHIHIRO
IPC: C09K23/52
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To open up new uses of a fine powder of an eggshell membrane and effectively utilize the powder. SOLUTION: This wet pulverized fine powder of an eggshell membrane is obtained by immersing an eggshell membrane in an alcoholic solvent and carrying out at least either of stone mortar type or rotating grinding and ball mill type pulverizing thereof. Since the wet pulverization is a specific pulverizing treatment, a relatively macroscopic fiber structure remains in the eggshell membrane. Since the fine powder of the eggshell membrane has excellent oil absorptivity or stabilizing ability of an emulsified composition, the fine powder can widely be utilized for new applications such as oil collecting agents, sebum removers, medicinal bases or cosmetic bases.

Title: Vertical sorting huller
Inventor: KAWASHIMA KENZO
IPC: B02B3/06
Filed: 1987-12-25
Abstract: PURPOSE:To integrate a huller and a sorter at a low cost and in a small floor area by composing the lower half of a grain-lifting spiral body of a hulling area of specified structure in a grain lifting spiral body and a vertical selective huller provided with a selective net body concentrically on its external circumference. CONSTITUTION:Paddy or uncleaned grain mixed with paddy is supplied to a grain receiving cylinder 12 provided on a base of the grain-lifting spiral body 30 to start operation. In the lower half of the grain-lifting spiral body 30 the pitch of a spiral blade 32 is small and the paddy rises slowly. On one hand, the selective net body 50 is provided near the spiral blade 32 of the grain-lifting spiral body 30 and accordingly the paddies hardly fall downward and they rise as the paddies make full hulling operation to each other. Since the pitch between the spiral blades 32 is rougher in a zone beyond the hulling zone the internal between the internal circumference of the selective net body 50 and the external circumference of the spiral blade 32 becomes larger, part of the paddies repeat falling in this zone and the uncleaned grain leaps out of small holes of the selective net body 50 to the outward.

Title: Saw blade
Inventor: SAWADA MINORU
IPC: B23D61/02
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To restrain generation of noise at cutting work time by arranging plural slits in a range of specific % of a radius from the center of a circular base board, and setting the total length of the slits to specific times the outer peripheral length of the circular base board. SOLUTION: Slits 4 are arranged in a range of 50 to 85% of a radius from the center of a circular base board 1 to thereby effectively restrain generation of noise at cutting work. The slits 4 of a part extended to a range less than 50% of a radius of the circular base board 1 or a range exceeding 85% of a radius of the circular base board 1 do not largely contribute to reducing noise. The total length of plural slits 4 is arranged so as to become 2.0 to 3.0 times the outer peripheral length of the circular base board 1. When the total length of the plural slits 4 is less than 2.0 times the outer peripheral length of the circular base board 1, there is the possibility of becoming insufficient in a restraining effect of generation of noise at cutting work time.  When the total length of the plural slits 4 exceeds 3.0 times the outer peripheral length of the circular base board 1, there is the possibility of lacking in strength of the circular base board 1.

Operation is controlled so as to generate reverse revolving torque smaller than forward revolving torque in a required number of the pinions 6a composed in the same diameter. Accordingly, the effect of backlash among the pinions 6 and the rack is not received, the traversing speed of the traversing frame 9 is kept constant, and the trouble of the hydraulic motors is prevented.

Next the glass moulded body is heated and fused at a temperature around the softening point of this glass moulded body, that is about 770 deg.C, by a heating means 46 so as to make the irregularities in the blast-worked mat surface almost spherical. After that, the glass molded body is taken out from the charging port 42 and cooled in air, so the irregularities in the mat surface are solidified in almost spherical forms, thereby a smooth frosting-worked surface to which contamination is not likely to attach and easy to be removed can be achieved.
