Title: Memory device
Inventor: ISHII KOJI
IPC: G11B5/09
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To cancel effects of non-linear bit shift and improve error rate by changing the amount of precompetition which shifts the switching point of the write current in the direction reverse to the non-linear bit shift at the time of read in accordance with environmental temperature. SOLUTION: The device is composed of a magnetic disk or the like which writes the information for demodulation to the medium by partial response most likelihood detection. The write-precompetition circuit 1 compensates for so that the peak position of the readout signal shifted at the time of read is corrected by delaying in advance and recording the timing of the switching point that gives the position of the boundary between a long interval of magnetic inversion and the next one succeeding a short interval of magnetic inversion. A setting and processing section 2 sets the optimum value of the amount of precompetition in the write precompetition circuit 1 in accordance with the environmental temperature T detected by a temperature sensor 3.

IPC: G05D3/12
Filed: 1988-06-20
Abstract: PURPOSE:To increase the operation rate of a motor and to precisely correct a moving quantity in a relatively short time by switching a closed loop control and an open loop control with a mode or a stopping position. CONSTITUTION:A command pulse generator PG1 receives a positioning command ST of the effect that a positioning action is started from a host device 01 and a point No. signal PNO to show the coordinate point number of a moving destination, obtains a command pulse P necessary for the positioning movement to the coordinates point of the point No. PNO, supplies it to a positioning device 02 and executes the positioning action. At the positioning control time at the ordinary coordinates point with a shorter stopping time, the open loop system is adopted and only at the time of controlling positioning to the coordinates point with a longer stopping time, the position is corrected by using the closed loop system. Thus, while the operation rate of the servo motor is increased, the moving quantity can be precisely corrected in a relatively shorter time.

Title: Ultrasonic wave thickness meter
Inventor: ONUKI KATSUHIRO
IPC: G01B17/02
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To measure thickness with precision in short time. SOLUTION: For a thickness of a steel plate 11, such reciprocation time as ultrasonic wave is reflected in a plurality of times between a front surface 11a and a rear surface 11b is measured with a timing counter circuit 17, and reciprocation frequency is counted with a reciprocation counter circuit 19, and a calculation circuit 18 calculates based on time, frequency, and sound speed. Since a measured time is longer than the amount equal to one reciprocation, even if a frequency of clock signal from a clock circuit 16 is not so high, a measurement error can be smaller easily for higher precision. Since high precision measurement can be done with a single application of ultrasonic wave, a high precision measurement in a short time is allowed compared to where a measurement is done at a single reciprocation after ultrasonic wave is applied and the next measurement is done after a reflection echo from repetition is fully attenuated, which is repeated.

Title: Carrier signal monitor system of automatic power supply controller
Inventor: HONDA MINORU
IPC: H02J13/00
Filed: 1989-06-14
Abstract: PURPOSE:To prevent a power input to a controlled apparatus at the time of momentary break of a carrier signal through a communication line trouble by monitoring the time from the stop of the carrier signal to the second reception of the signal in an automatic power supply device when the power of the controlled apparatus is not inputted. CONSTITUTION:An automatic power controller 13 detects the stop of a carrier signal in a carrier signal detection mechanism 1 for detecting the carrier signal and informs a monitoring mechanism 3 of the stop. The monitoring mechanism 3 starts a clock mechanism 4 for measuring the time from the stop of the carrier signal to the second reception of the signal. When the mechanism 1 detects the second reception of the carrier signal and informs the mechanism 3 of it, the latter stops the mechanism 4. The time from the stop of the carrier signal to the second reception is read from the mechanism 4. The apparatus 13 compares the time read from a storage device 2 and the time read from the mechanism 4. When the time from the mechanism 4 is shorter than that from the mechanism 2, the power of the controlled apparatus 14 is not inputted, but when longer, the power of the controlled apparatus 4 is inputted.

Title: Printing head
Inventor: TAKAHASHI NUSHITO
IPC: B41J2/28
Filed: 1982-09-03
Abstract: PURPOSE:To obtain a printing head having improved wear resistance in the contact face between an attraction part and an iron core and capable of stably operating for a long period of time by forming a wear-resistant portion in the contact face between the attraction part and the iron core. CONSTITUTION:In providing wear-resistant layers 13a, 13b, 14, 15a, and 15b in the contact face between an attraction part 2 and an iron core 5, the thickness of the wear-resistant layers near the point A is made sufficiently larger and those of the layers other than the point A are made smaller to an extent that the lowering of the printing performance can be extremely lessened. The wear- resistant layers can thus be formed in the attraction face without lowering of the attraction force, and thereby high-speed printing is made possible and the spring force can be kept constnt for a long period of time.

Title: Reading method for serial code

IPC: H01L21/02
Filed: 1986-07-01
Abstract: PURPOSE:To omit a straight line reading mechanism and to minimize the reading time of serial codes by scanning the serial codes arrayed on a straight line is the direction of a prescribed circular arc and correcting the obtained data. CONSTITUTION:The serial bar codes 2 are arrayed on the back side of a semiconductor wafer 1 and then scanned and read at a fixed angular speed along a circle 3 concentrical to the circle of the wafer 1. In this case, the codes 2 set along the tangent of a circular arc so that the middle point of the code 2 serves as a contact with the circular arc. Then DELTAx=(r.DELTAtheta)Xcostheta is satisfied, where the width of each code component is referred to as DELTAx together with the radius of a circular arc 11 as (r), the angle secured between the code component measured by the scan in the circular arc direction and the center of the arc 11 as DELTAtheta, and the angle between the code component and the middle point of the code as theta respectively. Then the correction is applied so as to obtain the code data when a circular arc 12 is scanned in the straight line direction. In a circular arc scan mode a bar code reading sensor is set at a prescribed position distant from the rotational center by the radius (r) when a wafer is rotated for wafer positioning in production of a semiconductor.

Title: Method of selecting transistor for parallel use
Inventor: NIWA MOTOMI
IPC: H01L29/80
Filed: 1989-06-15
Abstract: PURPOSE:To see that drain currents flow uniformly to each transistor during parallel use by equipping a mutual conductance being the index which shows how much the drain currents flow to the voltage between a gate and a source independent of gate currents. CONSTITUTION:Mutual conductance is determined by drain currents ID and voltage VGS between a gate and a source. That is, the mutual conductance becomes an index to show how much the drain currents ID flow to the voltage VGS between a gate and a source, independent of gate currents IG. Accordingly, in the case that transistor T1 and T2 are used in parallel, the voltages VGS between the gate and the source of the plural transistor T1 and T2 become equal to each other, so only the transistors that those mutual conductances have become equal are selected for parallel use. Hereby, drain currents can be made to flow equally to each transistor.

Filed: 1983-08-24
Abstract: PURPOSE:To attain the diagnois of a common bus of a CPU with use of the output of a voltage comparator by resetting the CPU with a switch and delivering the data of ''1'' or ''0'' to each signal line constituting the common bus. CONSTITUTION:A switch 7 is turned on the reset a CPU1, and the voltage V1 or V0 is set at a prescribed level while a driver 8 is delivering ''1'' or ''0''. While a reference voltage generating circuit 9 delivers the high or low level input voltage set by a system 5 while the driver 8 is delivering ''1'' or ''0''.

Therefore the impedance of the bus 4 has a change when an anomalous arises on a signal line of the bus 4, and the V1 or V0 of each signal line has fluctuation. This fluctuation is detected by the comparator 10.
