Title: Mechanism for detecting position of carriage of printer
Inventor: UCHIYAMA KANEATSU
IPC: B41J19/18
Filed: 1984-10-13
Abstract: PURPOSE:To detect the position of a carriage, by forming a timing belt having positional information recorded thereon into a loop and fixing a part thereof to the carriage while reading the positional information from the above mentioned belt by the position detection sensor mounted to the carriage. CONSTITUTION:A carriage 1 is attached to a timing belt 7 and a timing belt 7a is moved to the A-direction while a timing belt 7b is moved to the opposite B-direction with the rotation of pulleys 8, 9. The back surface of the timing belt 7 is constituted of magnetic powder filled rubber or a magnetic tape and information showing the position of the timing belt is recorded. Therefore, because the magnetic head 11 attached to the carriage 1 reads the positional information recorded on the back surface of the timing belt 7b, the positional information is read at a moving speed two times that of the carriage. As a result, positional detection accuracy is enhanced.

Abstract: PURPOSE:To obtain high density for recording by providing the positioning member of a head element guiding member in the prescribed part of a motor separated from the rotational center of the motor by a prescribed distance, abutting this guiding member to the positioning member and executing positioning. CONSTITUTION:A guide shaft 6 of a head carriage 4 to load a magnetic head 3 is fixed on a housing 20 of a motor 2. This guide shaft 6 is brought into contact with a projecting rib part 20a and a pin part 20b with pressure by the pressing of a leaf spring 10 and according to a radius R of the projecting rib part 20a, the guide shaft is positioned and fixed in the position separated from the rotational center of the motor 2, namely, from the center of a rotational central shaft 2a by the distance to correspond to the radius R. A carriage 4 can be moved along the guide shaft 6 in A and B directions being guided by this guide shaft 6 and can be turned in arrow C and D directions with the guide shaft 6 as a supporting point. Then, a magnetic head 3 is energized in the C directions, where the head is close to a magnetic disk 1. Thus, the high density can be obtained for the recording.

Title: Detecting method for magnetic signal by magnetism detecting sensor
Inventor: SUGIMOTO YOSHIYASU
IPC: G01R33/09
Filed: 1988-08-31
Abstract: PURPOSE:To obtain an output signal of 4 cycles per cycle of a magnetic signal and thereby to obtain resolution twice as high as conventional one by synthesizing two outputs obtained from first and second magnetoresistance elements. CONSTITUTION:A magnetism detecting sensor is so constructed that magnetism sensing members R11 and R12 of a first magnetoresistance element part 1A are spaced by 3lambda/16, magnetism sensing members R13 and R14 of a second magnetoresistance element part 1B by 3lambda/16 and R11 and R13 by lambda/4 in relation to a wavelength lambda of a magnetic signal. In this case, k1=k2=1/8 and n1=n2=n3=0. With the magnetic signal 10 and the magnetism detecting sensor shifted relatively, outputs V11 and V12 are taken out from terminals T1 and T4 and they are inputted to a differential amplifier 30. In this case, an output vol shown in the figure is obtained, and it is a signal of 4 cycles in relation to 1 cycle of the magnetic signal. Accordingly, resolution is made twice as high as conventional one and thus a motor or the like can be controlled more precisely.

Title: Method and device for thermally treating rail
Inventor: RICHIYAADO EE SOMAA
IPC: C21D9/04
Filed: 1987-08-28
Abstract: PURPOSE: To improve the friction characteristic without generating any thermal deformation by simultaneously heating both a head part and a flange part to the temperature exceeding the metallurgical transformation temperature, and rapidly cooling them after preheating a whole rail. CONSTITUTION: Firstly, a whole rail 10 is preheated to the temperature lower than the metallurgical transformation temperature by a preheating induction coil 40, and a head part 20 and a flange part 24 are simultaneously heated to the temperature exceeding the metallurgical transformation temperature by induction units 46, 48. The rail 10 is cooled by a rapidly head cooling part 54, a rapidly flange cooling part 56 and a water spray cooler 66. The thermal deformation around the neutral axis of the rail is balanced thereby, and the friction characteristic can be improved without generating the distortion.

Title: Ink jet color recording device
Inventor: ARAI TOSHIHIRO
IPC: H04N1/23
Filed: 1988-08-31
Abstract: PURPOSE:To brighten a color tone in a low gradation area and besides, to smooth variation in a color tone according to a gradation level by a method wherein for the number of striking of black dots, an increase of the number of dots corresponding to a gradation level signal is restrained in the low gradation area, and the increase of the number of dots corresponding to the gradation level signal is enlarged in a high gradation area. CONSTITUTION:For a threshold matrix for black 1, a unit area corresponding to one pixel is divided into 4X4 matrixes, and a threthold Tij is established to each of then. Then, power is applied thereto, and a gradation level signal Vij is inputted to a comparator 2. The comparator 2 compares the gradation level signal Vij with the threshold Tij of a threshold matrix 3 and only when it is larger than the threshold Tij corresponding to the threshold matrix 1, a recording signal is generated. Herein, since it is so set that as the threshold Tij grows higher, an increment becomes less, the number of increased dots per one gradation level grows larger as the gradation level signal Vij becomes higher. Thereby, a color lightens in a low gradation area, and a recording image of smooth variation in the color toner can be obtained in the all gradation area.

IPC: B41J32/00
Filed: 1988-08-31
Abstract: PURPOSE: To use two kinds of cassettes in correct combination by providing a unit arranged on a first cassette in order to supply power by operating a switch, a unit arranged on a second cassette in order to supply power by operating the switch operating unit on the first cassette. CONSTITUTION: When a first cassette ribbon 2 is loaded onto a typewriter, a tab 8 touches a right finger 52 and a switch locker 30 swings to the right relative to a movable bracket 18 thus opening a switch 60. Similarly, when a second cassette ribbon 2a is loaded onto a typewriter, a tab 44 touches a left finger 54 and the switch locker 30 swings to the right thus opening the switch 60. Subsequently, an electronic unit 66 detects open state of the switch 60 and the typewriter is conducted. If an unsuitable first cassette correction tape 10 is inserted, insertion of the left tab 44 is impeded because the opening 16 in the flat part 14 is made on the right side and since the switch locker 30 can not swing to the right, the typewriter can not be conducted.

Title: Sheet carrier device and picture image formation device
Inventor: NISHITANI HITOSHI
IPC: B65H5/16
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To carry a sheet in high reliabilty without staining a sheet surface even with the short size sheet in poor flatness. SOLUTION: None of nonconformity that a sheet tip is caught is caused (2) as a sheet pushing member 2 revolves in the D direction with no resistance even when the tip of the recording sheet rushes in (1). Additionally, when a rear end of the sheet comes immediately above a sheet carrier means (3), the sheet pushing member 2 works to push the rear end of the sheet from behind. Consequently, a sheet carrier mechanism carries the recording sheet by work to push the rear end of the sheet in comparison with conventional technique to carry it by friction force by dead weight of the recording sheet.
