Title: Synchro-servo amplifier
Inventor: HIROTA HACHIROU
IPC: G05B19/33
Filed: 1983-04-08
Abstract: PURPOSE:To reduce the error and, at the same time, improve the reliability of a miniaturized light weight synchro-servo amplifier, by comparing and calculating detected and oscillated analog angle signals at a CPU section after they are converted into digital signals. CONSTITUTION:An analog angle signal detected at a synchronous motor 1 and another analog angle signal oscillated by another synchronous motor 5 are inputted into a selecting circuit 6 and either one of the signals is selectively outputted to a converter where the signal is converted into a digital angle signal. The scales of both digital angle signals are compared and calculated at a CPU section 8. The CPU section 8 outputs a drive instruction, driving data, etc., to a pulse motor 4 so that the difference between the values of the angle signals can be diminished. By repeating this control, errors due to the mechanical reason of the synchronous motors and backlash errors which occur at gears of a transmission mechanism section, etc., can be eliminated and a highly reliable synchroservo amplifier can be obtained.

Title: Polishing method and abrasive tool
Inventor: IMANARI TORU
IPC: B24B37/00
Filed: 1987-03-19
Abstract: PURPOSE:To make a workpiece possible to be finished into good flat accuracy and surface roughness accuracy at high efficiency, by vibrating an abrasive tool, while making abrasive grains in an abradant collide with the work surface of an optical element from an oblique direction, and polishing it. CONSTITUTION:A tool active part 12d is reciprocatively moved in a V direction at amplitude (a) by vibration, and this amplitude (a) and a distance (b) are set so as not to come into contact with a polishing surface even in a position where the active part 12d is most approached to a workpiece 6. With this constitution, abrasive grains in an abradant 8 adjacent to the active part are accelerated to the workpiece 6 in the vibration direction, thus a work surface part D is polished. At this time, since a flow of the abradant is produced to go along the vibrating direction V, the abradant 8 inclusive of these abrasive grains once related to the polishing is moved to the outside of a polishing position, where by at the lower part of the tool active part 12d, a new abradant is fed to the polishing position from the right, so that polishing is performed in good efficiency.

Title: Communication equipment with picture reader
Inventor: KONDO MITSUNOBU
IPC: H04N1/04
Filed: 1988-03-15
Abstract: PURPOSE:To prevent wasteful power consumption, and to improve operability by turning an original carrying roller into a stop state when the non-loaded state of a picture reader is detected by a loading state detecting means. CONSTITUTION:When the non-loaded state of the reader 4 is detected by a detecting sensor 15, a pulse motor is not rotated even if the read of an original is started by 8 start switch 5, and the carrying roller 13 is not driven to rotate. Besides, in a case that the title device is used while the reader 4 is detached from a device main body 2, since the reading operation of picture data is finished automatically if the reader 4 is turned into the stop state, an operating panel 7 need not be provided with a functional key for finishing the reading operation, and the number of the functional keys can be reduced, and misoperation can be dissolved. Thus, the prevention of the wasteful power consumption and the improvement of the operability can be realized.

Title: Image input device
Inventor: OKADA HIDEO
IPC: H04N5/335
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To eliminate moires and to reduce the power consumption of an image input device which can input images in the 1st resolution and also in the 2nd resolution improved by an image shift means. SOLUTION: A refraction plate 12 is tilted by means of a piezoelectric element 14, so that the incident position can be shifted to a solid state imaging device 13. When such position shifted images are composited an image of the high 2nd resolution is obtained. When an unshifted image of the normal 1st resolution is inputted, an input optical path Z' is finely and fast vibrated to the device 13 and the resolution of the image inputted to the device 13 is equivalently reduced. As a result, the moires are eliminated. A moire elimination means 19 operates only when a moire detection means 18 detects the moires. Thus it is not needed to operate the means 19 as long as no moire is detected and therefore the power consumption is reduced for an image input device.

Title: Mixing device for hot water and cold water
IPC: G05D7/00
Filed: 1992-03-19
Abstract: PURPOSE:To prevent an actual cold water and hot water mixed flow rate from being saturated at a value remarkably less than the upper limit of a set range of a target flow rate setting means when the pressure of supplied hot water or cold water decreases. CONSTITUTION:This device is a mixing device for hot water and cold water equipped with a control means 11 which operates flow rate valves 7, 8 so as to obtain mixture of cold water and hot water of target flow rate set by target flow rate setting means 12a, 12c based on the detection information of a flow rate detecting means 10 which detects a clod water and hot water mixed flow rate. In such a case, the control means 11 finds the target flow rate based on an instruction value set by the target flow rate setting means 12a, 12c. Also, the means corrects relation between the instruction values extending over all the setting ranges and the target flow rate setting the cold water and hot water mixed flow rate at that time as the target flow rate for the maximum instruction value when the flow rate valves 7, 8 are fully opened with the cold water and hot water mixed flow rate less than the target flow rate.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide an illumination apparatus which is low in production cost, can be miniaturized and is capable of efficiently illuminating an object to be illuminated. SOLUTION: This illumination apparatus is larger in the bore of the core of an optical fiber 33 at the other end face 32b than the one end face 32a of an optical fiber plate 32 and, therefore, the light is made incident on the inside of the optical fiber 33 at the one end face 32a and is emitted from the inside of the optical fiber 33 at the other end face 32b, by which the parallelism of the light is enhanced. The optical fiber plate 32, therefore, is commonly used as optical parts for increasing the quality of the light taken out of a light emitting diode 43 and optical parts for enhancing the parallelism of the light and the number of the optical parts is decreased.

Abstract: PURPOSE:To eliminate the bending, crazing, etc. of the cables at the junction of the cables and connecting box by fixing the connecting box provided with a working platform to a pole and by housing the connection part of the optical cables installed between poles into the connecting box. CONSTITUTION:Support fittings 4 are protruded from a pole 3 and a connecting box 2 is placed thereon.

Abstract: PURPOSE:To improve the efficiency of a test by a method wherein a non-selected word line is set at an intermediate potential and the potential is made to leak to data holding nodes of all non-selected cells so that an unstable state is brought fort, during a test period. CONSTITUTION:In a row decoder 11 decoding an address signal and selecting a word line WL, a signal TST of a test terminal 11f is made to be at an H level of a test mode. Then PMOS 11c turns OFF, while NMOSs 11d and 11e turn ON, and the drain of NMOS 11b is set at an intermediate potential VM. Accordingly, the potential VM is given to all buffers B0, B1, B2... and potentials of non-selected word lines WL1, WL2... are set to be VM. During a prescribed test mode period, in this way, the potentials of all of the non-selected word lines are set at the intermediate potential and all of non-selected cells are put in an unstable state simultaneously. By making selected word lines zero, accordingly, all word lines are made non-selected, all memory cells are put thereby in the unstable state in one test and thus a test time can be shortened.
