Title: Laser beam machine
Inventor: TSUTSUI KIKUO
IPC: B23K26/082
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To perform laser machining with high precision and to reduce the required space by mounting a laser beam oscillator on the upper surface of the machine body having the upper face and the side face set at right angles to each other. SOLUTION: The X-axis carriage 9 is moved in the X-axis direction, as is the Y-axis carriage 17 in the Y-axis direction and Z-axis carriage 19 in the Z-axis direction; the laser beam machining head 21 is thereby positioned at a prescribed position of a work W placed and fixed on a machining table 23. As a result, the X-axis carriage 9 is easily placed at a right angles to the machine body 3, and also the Y-axis carriage 17 can easily be placed at a right angles to this X-axis carriage 9. In addition, the Z-axis carriage 19 can easily be placed at a right angles to the Y-axis carriage 17; therefore, a parallelism is easily obtained between a laser beam LB from a laser beam oscillator 25 and the driving system of each axis, enabling laser beam machining to be performed with high precision.

Title: Backlight for liquid crystal
Inventor: SAKUMOTO TORU
IPC: G02F1/13357
Filed: 1992-12-09
Abstract: PURPOSE:To make interference fringe inconspicuous by finely varying the lighting frequency of a fluorescent tube by lighting an inverter oscillation circuit in varying width which is at least larger than the frame frequency of liquid crystal display. CONSTITUTION:By giving power source voltage, an alternating current being a base modulating inverter oscillation frequency is generated in a suboscillation circuit 14, and the inverter oscillation circuit 13 is driven by a modulation circuit 15 so as to generate the alternating current of which the frequency is finely varied. Furthermore, the alternating current is boosted in a high voltage generation circuit 12, and the fluorescent tube 11 is lighted to obtain the backlight for liquid crystal where the lighting frequency is finely varied. Since the oscillation frequency of the circuit 13 is finely varied also by the fine variation of the power source voltage, the backlight for liquid crystal where the lighting frequency is finely varied by finely varying the power source voltage is obtained.

Title: Initial position set device for film count mechanism of film unit with lens
Inventor: MORITA MASAYA
IPC: G03B17/04
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a device that the film count mechanism of a film unit with a lens is set at an initial position in order to be reused. SOLUTION: Since the rotation of a counter plate 52 is locked by a shutter mechanism set in a release state on condition that scale '0' coincides with an index 67b and the final tooth 63c of a stepping gear 63a abuts on a driving gear 55h when the film unit with a lens is completely used, the lock of the rotation is released by switching the shutter mechanism to be a charge state first. Then, the plate 52 is rotated by utilizing a toothless part 63b so that an initial tooth 63b abuts on the gear 55h and scale B is made to coincide with the index 67b. Next, a sprocket coaxially engaged with the gear 55h is rotated so that the gear 55h and the gear 63 are meshed. Thus, the counter plate 52 is set at the initial position where scale A coincides with the index 67b.

Title: Thin film magnetic head for perpendicular recording
Inventor: KANAMINE MASAAKI
IPC: G11B5/31
Filed: 1989-12-19
Abstract: PURPOSE:To improve efficiency of recording and reproducing by forming the coil of a magnetic head in a manner that a helical coil is folded into half turns with the main pole as the center thereof, the half turns of the coil are disposed perpendicular to the helical coil plate, facing to each other interposing the main magnetic pole, and that ends of each half turn are connected to form a circuit. CONSTITUTION:The coil 13 of the head is formed by folding a helical coil 14 along a line 17 in a manner that half turn parts 15, 16 are raised in the direction 18, 19 as shown in the figure, and bottom ends of each half turns 20, 21 are connected as shown by number 22 in the figure. In the case of recording, both of the half turn parts 20, 21 have the effect of magnetizing the main magnetic pole 11 and can generate stronger magnetic field than a conventional head by about 20 %, which gives high recording efficiency, since the top end 11b of the main magnetic pole 11 can be directly magnetized. In reproducing, leaked magnetic flux along the main magnetic pole crosses the half turns 20, 21. This means all of the magnetic flux from a recording medium to the magnetic pole through the top end 11b can be used without any loss for reproducing. Thereby, reproducing efficiency can be improved and higher output can be obtained compared with a conventional head.

Title: Detection of disconnection of optical cable
Inventor: ITO MASAHIRO
IPC: H04B3/46
Filed: 1990-11-30
Abstract: PURPOSE:To facilitate the correct diagnosis of the presence or absence of the disconnection of an optical cable by detecting whether the power source of the present optical communication device is on or off and providing a optical switch for switching the looping of the other optical signal transmission side transmission path or the connecting thereof to the present optical signal reception section according to the result of this detection. CONSTITUTION:The optical switch 3 shifts to a switch contact side shown by a solid line if a power source is off. The light signal past the optical cable 8 passes an optical connector and is looped back by the optical switch 3 and is returned through an optical coupler 4 and an optical connector 7 to the other optical communication device. The optical 3 shifts to the switch contact side shown by a broken line if the power source is on. The light signal past the optical cable 8 is then inputted through the optical connector 7 and the optical switch 3 to an optical signal reception section 5. The light signal outputted from the optical signal reception section 6 is outputted through the optical coupler 4 and the optical connector 7 to the optical cable 8. Then, the light signal from the other optical communication device is looped back even if the power source is uncharged and, therefore, the detection with the other optical communication device is possible and the optical cable is recognized to be not disconnected. Whether the optical cable is disconnected or not is correctly detected in this way.

Title: Controller for machine tool equipped with automatic tool changing device
Inventor: OHASHI HAJIME
IPC: G05B19/18
Filed: 1990-11-30
Abstract: PURPOSE:To eliminate the interruption of automatic operation in the case of a tool which is already corrected by including the item of a temporary stop flag in data on each tool which is written in a tool data file. CONSTITUTION:The item of the temporary stop flag is added to data items of respective tools which are written in the tool data file 60. When tool replacement is commanded in an NC program, a main control part 10 outputs an auxiliary code and reads tool data out of the tool data file 60 and when the temporary stop flag is ON, a means 65 outputs a temporary stop command to a machine control part 70. The temporary stop flag is reset for a tool whose correction is completed at a temporary stop. Consequently, even if there is the command for tool replacement in the program, the temporary stop is made only when necessary and skipped in other cases, so unmanned automatic operation can be carried on.
