Title: Copying machine
Inventor: ADACHI HIDEKI
IPC: G03G15/041
Filed: 1983-07-20
Abstract: PURPOSE:To enable rapid movement to a designated position of an optical lens in accordance with a varriable power by enabling gradual change from the first movement speed of the optical lens to the second speed on reaching to a position apart by a designated distance from a position corresponding to a designated magnification. CONSTITUTION:The peripheral part of a disc 8 directly connected with a rotating shaft of a DC motor 21 is provided with, e.g., 20 holes at equal intervals, the light transmissions through these holes are detected with a photointerrupter 27, and the rotation of the motor 21 is converted into a series of pulses. The arrival of a zoom lens 3 at the predetermined standard position P1 is detected by intercepting a photointerrupter 30 fixed at the position P1 with an intercepting plate 29. These detection pulses and data on copying magnification designated from ten-keys 34 are fed to a microcomputer 33, and it controls a normal and reverse motor rotation changing circuit 31 and a high and low speed changing circuit 32 in accordance with an instruction from a lens movement start instruction switch 35 to drive the motor 21, and the lens 3 is moved in speeds corresponding to the movement distance and stopped at the position corresponding the designated magnification.

Title: Light detection apparatus
Inventor: IWASAKI JUN
IPC: H01L31/10
Filed: 1985-06-18
Abstract: PURPOSE:To facilitate variation of the position, the shape and the transmittance of a light detecting part only by changing a filter by providing a space filter, composed of a light shielding film which transmits only the light of a required shape and at a required position with a required transmittance, on the upper surface of a main body of a semiconductor light detection element. CONSTITUTION:A space filter 5, composed of a light shielding film which is so formed as to cover the circumference of the upper part of a P-type diffused layer 3, is formed at the same time as metal electrodes 4 are formed by evaporation of aluminum. At that time, mask pattern for forming the metal electrodes 4 and mask pattern for forming the space filter 5 are provided in a same mask so that the metal electrodes 4 and the space filter 5 can be formed simultaneously only by using this mask and the process can be simplified. Therefore, as the space filter 5 is composed of an aluminum film, light can be accepted only by the parts W1 and W2 which are not covered with the space filter 5. With this constitution, a light detection apparatus with a light detecting part of a required position and a required shape can be obtained only by changing the mask for forming the space filter 5.

Title: Method of molding spigot of porous plastic tube
Inventor: OOTA RIYOUZOU
IPC: B21D26/02
Filed: 1979-10-12
Abstract: PURPOSE:To enable molding of a spigot which has an inner surface accuracy equivalent to that of a spigot of a holeless plastic tube, by a method wherein the end of a plastic pipe having a large number of holes in the direction of a pipe axis in a pipe wall is pressedly inserted into a spigot-forming mold under a heating condition. CONSTITUTION:The end of a porous pipe 3 having a large number of holes in the direction of a pipe axis in a pipe wall is heated, and said heated portion is pressedly inserted into a gap between a spigot-forming mold 1 and an outer mold 2 to be enlarged into a spigot. After a hole in the end 31 of the plastic pipe is closed by means of a proper system, a pressure medium, such as pressurized air P, is pressedly fed into through the hole in an end 32 of the plastic pipe. Feeding-in with pressure of said air P pressurizes the hole in he end of the porous plastic pipe between  the molds 1 and 2, and said hole makes contact with a surface, where inner and  outer pipe walls and said walls make contact with the molds, is increased in the pressure. This prevents the occurrence of waving at a spigot cross section, and  permits the formation of a smooth inner surface of the spigot.

Title: Comb-line filter
Inventor: SAKASHITA HIROHIKO
IPC: H04N9/78
Filed: 1985-06-18
Abstract: PURPOSE:To reduce dot disturbance by permitting a comparator to decide the correlation of a color for 1H and using a comb-line filter when there is no vertical correlation. CONSTITUTION:Where chromaticity is not constant for 1H, the outputs of the 1st chroma band-pass filter 15 and the 2nd chroma band-pass filter 17 are different from each other. Then the output of the comparator 17 moves the 1st and 2nd switches 19 and 20 downward, and the output of a chroma trap 18 is outputted from the 1st switch 19, while from the 2nd switch 20 the output of the 2nd chroma band-pass filter 16 is outputted. When color video signals with different chromaticities for 1H arrive in such a way, automatically the comb-line filter is removed to use the chroma trap and the chroma band-pass filter, whereby the dot disturbance arising in the lateral direction of a screen can be suppressed. Then the dot disturbance in the longitudinal direction of the screen can be suppressed by the comb-line filter.

IPC: G11B5/147
Filed: 1983-07-22
Abstract: PURPOSE:To obtain a magnetic head having high efficiency by constituting the 1st core to be disposed on the upper stream side of an Fe-Si-Al crystalline alloy and the 2nd core to be disposed on the down stream side of a soft magnetic material having higher magnetic permeability than the 1st core. CONSTITUTION:A soft magnetic material having higher B10 than the 2nd core 23 is used for the 1st core 22 and the sectional area at the tip part 25 where the magnetic flux flows is made narrower than that of the tip part 26 of the core 23 to permit easier magnetic saturation. On the other hand, a soft magnetic material having higher mue than the core 22 is used for the core 23. The magnetic flux of the magnetic field near the part 26 changes sharply as shown by the broken line in the figure. The smaller demagnetizing effect for the record is required for such magnetic flux distribution when a magnetic tape 21 passes and a magnetic head having high efficiency is obtd. An Fe-Si-Al crystalline alloy is adequate as the core 22 and an amporphous alloy of Co-Fe-Si-B or the like is adequate as the core 23. A composite material formed by dispersing uniformly and three-dimensionally at least one kind of the 2nd phase particles in an ultraquickly cooled alloy matrix consisting of an amorphous, crystalline or mixed phases thereof is adequate as the core 23.

Title: Routine data detecting circuit
Inventor: MOROMOTO HIROYUKI
IPC: G06F5/00
Filed: 1987-05-29
Abstract: PURPOSE:To obtain a routine data detecting circuit which can detect the routine data in a simple constitution by providing two shift registers and two arithmetic circuits. CONSTITUTION:A 1st shift register 12 receives the routine data sent repetitively in a prescribed pattern at its input terminal and stores the minimum unit of the repeating cycle. A 1st arithmetic circuit 13 discriminates whether the data pattern stored in the register 12 is equal to a prescribed one or not and outputs this discriminated data in the binary 0 or 1. Furthermore a 2nd shift register 14 has the same number of stages equal to the repeating frequency of the minimum unit of the routine data and receives the supply of the output of the circuit 13. While a 2nd arithmetic circuit 15 obtains the output that discriminated whether the data on the prescribed number of stages stored in the register 14 are all equal to each other or not. In such a constitution, it is just required for the first stage part to perform the bit precessing for detection of a minimum pattern and also for the rear stage part to perform the arithmetic processing of the bits in the same number as the repeating frequency. As a result, the number of component elements can be decreased.
