Title: Position signal detector
Inventor: WATANABE AKIO
IPC: G05D3/00
Filed: 1989-06-15
Abstract: PURPOSE:To mainly stabilize a closed loop control of a stepping motor by knowing an irregularity in the switching point of a position signal from time of duration between the switching of an exciting phase and the signal from a sensor. CONSTITUTION:Assume that the rotor of a stepping motor 3 is excited in phase with a point X as an equilibrium point to be stopped at the point X. When an excitation is switched to a phase having an equilibrium point Y, the rotor is moved toward the point Y. Time tXa from the time of switching to the phase having the point Y to the time of switching of the signal at a point (a) is measured. Similarly, when the Y is switched to the X, the time tYa to the switching of the signal is measured. A positional relationship between the equilibrium point and the switching point of the signal position is obtained by the ratio of the tXa to the tYa. If two types of position signals are provided, the positions of the whole switching point from the positions of four points (a), (b), (c), (d) of a rise and a fall are obtained. Thus, more stable control can be realized.

Inventor: TAKIGAWA TADAHIRO
IPC: H01J37/304
Filed: 1984-07-26
Abstract: PURPOSE:To reduce any out of focus and position slips in image drawing process due to irregularities in wafer by a method wherein, when an image is drawn while continuously shifting a stage, any out of focus and beam slips due to vertical movement of the wafer are compensated as functions of wafer positions. CONSTITUTION:A stage is shifted step-and-repeatedly to detect both mark positions and height in (z) direction per block. Next any position slips of beams in case of vertical movement of a wafer and resultant dynamic focussing are predicted and then those slips in addition to the slips from optimum values of mask positions are drawn into a correction map along the wafer to be stored in a storage circuit 243. When an image is drawn while continuously shifting the stage, the image drawing process may be assured of high precision by means of correcting both focus and positions in terms of said correction data.

Title: Measuring apparatus for insoluble component in lubricating oil
Inventor: KATO NAOYA
IPC: G01N21/27
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the measurement precision due to adhesion of particles to a prism and glass surface of an optical sensor in an apparatus for measuring the concentration of particles of insoluble components in a lubricating oil. SOLUTION: A lubricating oil of which the concentration of insoluble component particles is to be measured is introduced into a measurement chamber 14 from an oil line of an internal combustion engine through a flow route 2. A sensor 15 is installed in the measurement chamber 14 and the concentration of particles of insoluble components is measured by utilizing light absorption, reflection, transmitting or the like. Since ions produced by ionization by an additive in the lubricating oil adhere to the particles and the particles bear electric charge, the particles are vibrated and prevented from adhering to glass face of the sensor by applying AC voltage or current to the lubricating oil from an AC power source 4.

Title: Information recording/reproducing device
Inventor: OUCHI SATOSHI
IPC: H04N5/783
Filed: 1994-07-07
Abstract: PURPOSE:To attain excellent data reproduction even when an off-track exists on a pattern at a reproducing time by thoroughly reproducing recording information recorded on the pattern when a recording medium is reproduced. CONSTITUTION:A data signal or a control signal sent from a computer, etc., is recorded on a tape pattern 8 shown by an oblique line. When the data signal recorded on the pattern 8 is reproduced, a tape running speed is made 1/real number-fold of the time at a recording time, e.g. 1/N (N=1, 2, 3...). Then, the control is performed so that the tracing locus 9 of a reproducing output read means 7 such as a magnetic head, traverses the pattern 8 like the oblique line by dividing to real number times, and the data signal recorded on the tape pattern 8 is read dividing to real number times. In such a case, even when the head 7 traces a part excepting the pattern 8, a read signal is discriminated so that an error is a different tape pattern signal. Thus, the data recorded on the pattern 8 are reproduced thoroughly.

Filed: 1983-08-25
Abstract: PURPOSE:To improve comfortableness by judging the transition state in heating from the heating capacity of a heater and decreasing the heating effect during transition state, in an air conditioner equipped with the heater which utilizes engine cooling water. CONSTITUTION:The information of a car-interior temp. setting resistance 16, room temp. sensor 17, and an outside air temp. sensor 18 is input into a temp. controlling circuit 15 to control an air mix damper AM. The heating capacity signal of a heater which is outputted by a cooling-water temp. sensor 22 is compared with the standard values which are determined by partial voltage resistances 23-26 by comparators 27-29, and the heating capacity is judged stepwise, and each high level signal is output according to water temp., for example, at 80 deg.C or more, 50 deg.C or more, and 30 deg.C or more. Therefore, when the water temp. is 80 deg.C or less, the output of the comparator 27 turns ON a transistor 31, and a correction resistance 32 is connected to a room temp. sensor 17, and the detection temp. 17 is increased apparently. Therefore, the air mix damper AM is set in the direction of decrease of heating effect, and comfortableness can be improved.

Title: Mandrel bar
Inventor: SEGUCHI YUKIYOSHI
IPC: B21B25/00
Filed: 1993-06-28
Abstract: PURPOSE:To reduce the manufacturing and running costs of a mandrel bar by dividing the mandrel bar into working bars directly necessary to rolling and a dummy bar different from them and sharing the dummy bar. CONSTITUTION:When the dummy bar 8 is rolled by the mandrel mill 5, its outside diameter is unnecessitated to be equal to that of the working bars 7. However, since the dummy bar enters the mandrel mill 5, it must take a circular section. Consequently, one dummy bar 8 can join to plural working bars 7 having a little different diameters. Some working bars 7 are damaged because they are rolled together with a shell 4 and when the damage grows, they are disused. Therefore, the working bars are manufactured in consideration of the number of the disused working bars. As a result, since one dummy bar can be manufactured to plural working bars, the manufacturing and running costs are reduced compared with that of a long mandrel bar.
