Title: File processing system for duplex system
Inventor: KAWAMOTO JUNICHI
IPC: G06F11/16
Filed: 1991-01-11
Abstract: PURPOSE:To simplify the operation and to save the useless time by carrying on the write of information to a file at the stand-by side without repeating the same operation when breakdown occurs in a file write state at the on-line side. CONSTITUTION:When a CPU 12a, for example, writes the registered information into a hard disk device 20 at the on-line side, the information is converted into a code and written into a memory 13b provided at the stand-by side. Thus the CPU 12a is switched to a CPU 12b when the breakdown occurs at the on-line side in a file write state. Then the CPU 12b reads out the contents of the memory 13b as they are without receiving any operation in particular and writes the contents into the device 20. Thus the registered information can be surely filed.

Title: Semiconductor device
Inventor: KUBO KAZUYA
IPC: H04N5/369
Filed: 1988-01-11
Abstract: PURPOSE:To enable the increasing of mutual conductance without increasing the gain of an amplifier, by setting a source potential nearly equal to the substrate potential of a signal processing part, and making the differential resistance of a light receiving part a value in the vicinity of the maximum value. CONSTITUTION:In order that the applied voltage to an input gate IG might approach, as closely as possible, the ground potential being a substrate potential, a quantity of AV2 is, as shown by a dot-and-dash chainline IV, shifted toward zero potential direction. A differential resistance R, however, changes toward a small value, if the state is continued as it is. Therefore, in order to obtain the maximum value, a negative bias voltage is applied to a photo diode 1, so that voltage-current characteristics of the photo diode 1 is shifted as shown by a dot-and-dash chain line III. As a result, the operating point moves as shown by the point of intersection B of characteristics III and IV. Thus the mutual conductance gm can be increased as compared with conventional cases, without increasing the gain A of an operational amplifier 6.

Title: Dispersant for emulsion polymerization
Inventor: KASAI SATORU
IPC: C08F2/26
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To obtain the above dispersant capable of suppressing both the stability deterioration and foaming tendency of a system in producing an emulsion latex or conducting a polymerization, consisting of a water-soluble sulfonated product of styrene-based polymer with specific weight-average molecular weight and sharp molecular weight distribution.

Title: Non-contact measuring method for ultrasonic wave
Inventor: INOUCHI TOORU
IPC: G01N29/24
Filed: 1982-01-12
Abstract: PURPOSE:To measure the ultrasonic wave oscillation of a high temperature substance or high speed moving body at high SN ratio by dividing laser light into a measuring beam and a reference beam, and detecting the reflected light from each body to be measured by the same photodetector. CONSTITUTION:Light from a laser light source 1 is divided into two beams by a beam slitter 2 and the measuring beam 6 out of the two beams is phase- modulated by the displacement of oscillation at a measuring point 10 on the body 4 to be measured and its reflected light is transmitted to the photodetector 5. The other reference beam 7 is phase-modulated by the displacement of oscillation at a reference point 11 close to the measuring point 10 and transmitted to the detector 5, where both the beams are composed to form an interference beam. Since the air layer on the surface of a high temperature substance to be measured is oscillated by heat or a moving body is vertically oscillated, both the beams are modulated, but when the distance between the measuring point 10 and the reference point 11 is sufficiently short, the phenomenon that these modulations are offset each other is led from calculation formulas. Thus only the ultrasonic wave oscillation of the body to be measured can be measured at high SN ratio without the influence of these modulation.

Title: Decentering detector
Inventor: FUJIWARA YASUHIDE
IPC: G11B7/085
Filed: 1990-01-10
Abstract: PURPOSE:To realize the high-speed detection of decentering by generating an edge pulse from an RF signal from which an offset is removed and a tracking error signal. CONSTITUTION:The RF signal (a) from which the offset is removed by an AC coupling circuit 11 is binarized into a signal (c), and the tracking error signal too is binarized into the signal (d). The signals (c), (d) are inputted to a monostable multivibrator MMB 14, and it outputs the edge pulse EP (e) at the rise-up of the signal when the signal (d) is a high level. The MMB 15 outputs the EP (f) at a fall when the signal (d) is the high level. A moment when the EP (e) is turned into the EP (f) shows the decentering direction of an optical disk, and the number of the EPs (e), (f) shows eccentricity. A D-flip flop FF 17 latches the output of the DFF 16 by the EP (f), and outputs a non- inverted output signal as a decentering direction detection signal (g). A counter 18 counts the EP (f) reset by the signal (g), and detects the eccentricity. Thus, the decentering of the disk can be detected at high speed.

Title: Ink jet recording device
Inventor: FUJIMURA YOSHIHIKO
IPC: B41J2/06
Filed: 1989-01-12
Abstract: PURPOSE:To prevent a recording sheet from becoming charged and ensure that there are no printing error, deterioration of image density and ink overflow by applying a bipolar voltage when an electrostatic field generating device for allowing ink to be sent flying to a recording sheet side from an ink discharge section is driven with application of a high voltage. CONSTITUTION:A high voltage is applied to an area between a head-side electrode 20 and an electrode for generating an electrostatic field 21 of the main unit 2 of a recording head. However, if this condition is left as it is, air between the main unit 2 of the recording head and a recording sheet 5 becomes ionized resulting in the charged surface of the recording sheet 5. A timing controller 28 transmits a signal to an AC high voltage power supply 27 so that an AC high voltage is applied to the electrostatic field generating electrode 21 after the lapse of a specified time following the application of a DC high voltage pulse. This AC voltage is applied after the lapse of a specified time following the application of a thermal pulse, and in this case, the temperature of the ink should preferably be low. Furthermore, the peak-to-peak value of the AC voltage is set so that a value equal to 1/2 the peak-to-peak value is higher than the pulsed voltage.

Title: Rotary magnetic head device
Inventor: NEJIME KUNITAKA
IPC: G11B5/53
Filed: 1988-01-13
Abstract: PURPOSE:To make the projection amount of the magnetic head adjustable and to make the projection of the magnetic head unchanged even if a drum is driven at a high speed by driving an eccentric pin in press contact onto a pressing part formed to a head base. CONSTITUTION:The device is provided with the head base 3 fitted to the drum movably in the radial direction of the drum 1 while mounting the magnetic head 2 and the eccentric pin 5 in press contact onto the pressing part formed to the head base 3 to move the head base 3 radially. Then a pressing force of the eccentric pin 5 is made nearly opposite to the acting direction of the centrifugal force caused by the drive of the drum 1. Thus, even with a large centrifugal force caused, the force in the direction of the centrifugal force acting onto the head base 3 is suppressed and the movement of the head base 3 is prevented. Thus, the projection amount of the magnetic head 2 is kept always constant.

IPC: B29C48/92
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To nicely hold the dimensional accuracy of a pipe diameter by comparing the detection value detected by a pipe diameter detection sensor with the set value of the pipe diameter to operate the value of the pressure applied to the outer peripheral surface of a thermoplastic resin pipe and adjusting the pressure applied to the outer peripheral surface of the thermoplastic resin pipe by an expanding and contracting means. SOLUTION: The pipe diameter of a molten resin pipe 6 is individually detected by an X-direction pipe diameter detection sensor 25 detecting the pipe diameter in a horizontal direction and a Y-direction pipe diameter detection sensor 26 detecting the pipe diameter in a vertical direction and the set value of the pipe diameter and the detected values are compared by a central data operational processing apparatus 27 to operate the respective pressure values applied to the outer peripheral surface of the resin pipe 6.  At that time, when the values in the X- and Y-directions are sifted from a set value in a diameter expanding or contracting direction, pressure values are designated to a vacuum pressure adjusting device 18 and, when the value only in the Y-direction is shifted, a pressure value is designated to a roll clamping pressure adjusting device 2 and, in the case only in the X-direction, a pressure value is designated to a taking-over machine clamping pressure adjusting device 22. Therefore, the pipe diameter can be always held to the value near to the set value.
