Abstract: PURPOSE:To obtain the subject resin, having a uniform particle diameter and high acetalization degree without any blocking or sticking to walls by reacting a PVA solution with an aldehyde in the presence of an acidic catalyst according to a specific method. CONSTITUTION:An aqueous solution of PVA (preferably having 200-10000 average polymerization degree and >=88mol% saponification degree) is mixed with an aldehyde (preferably acetaldehyde, propionaldehyde, etc.) at a temperature of 20 deg.C to <= the boiling point of the aldehyde so as to provide 100-180 mol% aldehyde based on 100mol% residual hydroxyl group in the PVA. The resultant mixture solution is then mixed with an acidic catalyst (e.g. hydrochloric acid or sulfuric acid) at 70-95 deg.C to carry out the reaction. Furthermore, the aqueous solution of the PVA is preferably mixed with the aldehyde by a method for charging the PVA into hot water at >=80 deg.C, dissolving the PVA therein, cooling the obtained aqueous solution, regulating the cooled aqueous solution to a temperature within the range of 20 deg.C to the boiling point of the aldehyde and then charging the aldehyde into the aqueous solution of the PVA.

Herein, SiO 2  has low wetting to the iron and iron oxide, and decreases the cubical expansion. Further, because the ZrO 2  composed of MgO, CaO, TiO 2 , Fe 2 O 3 , Al 2 O 3  and metals such as Ni, Co, etc., has high wetting to the iron and iron oxide, the ZrO 2  stabilizer is made to be not more than 5% to achieve the purpose of stabilization and not to generate the ill effect of abovementioned wetting. Thereby, the roll surface film can be prevented from exfoliation, and the fittings to the roll surface of the iron and iron oxide brought with steel strip can be decreased.

Title: Synchronizing signal detection circuit
Inventor: SHIRAHATA MIYUKI
IPC: H04N7/08
Filed: 1995-02-14
Abstract: PURPOSE: To prevent mis-detection of a frame synchronizing signal and reduction in the detection frequency. CONSTITUTION: Frame synchronizing signals have non-correlation between two lines and between 4 clocks. A correlation detection means 2 detects respectively non-correlation between two lines and a correlation detection means 3 detects non-correlation 4 clocks. Simultaneously the non-correlation is detected, an AND gate 4 provides an output of an H signal. A control means 5 counts up a counter 6 when the output signal is logical H and counts down the counter 6 when the output signal is logical L and is reset when logical L is consecutive for a prescribed period. When the count of the counter 6 exceeds a threshold level (n), a comparator 7 provides an output of a synchronization detection signal.  A counter 11 is reset when the counter 6 is reset simultaneously to count clock signals from an input terminal 10 and a comparator 12 generates a timing signal when the count is within a lower limit m1 and an upper limit m2. When the synchronization detection signal and the timing signal are generated simultaneously, a synchronization discrimination means 9 discriminates a frame synchronizing signal.

Title: Sequential controller with time delay operation output
Inventor: OGURA NOBUYUKI
IPC: G05B7/02
Filed: 1982-02-22
Abstract: PURPOSE:To prevent output of an unnecessary operation command for switching from the manual control to the automatic control, by providing a function which executes a step suitable for the current state of a control object device group when the automatic sequential control is started. CONSTITUTION:When a sequential start command 11 is inputted, a start command 12 to a device A is outputted after a time (t) by a time delay element. As a result, a feedback signal 21 of the start completion of the device A is inputted, and the sequence control advances to the second step. Hereafter, the sequence control advances to the third and the fourth steps similarly. Now, the automatic control is stopped in the stage where the sequential control advances to the second step, and the control is allowed to advance to the fourth step by the single manual operation, and the command 11 is inputted again to return the control to the automatic sequential operation. Then the sequential control starts from the first step again; but since feedback signals 21, 31, and 41 are already inputted while the command is delayed by an element 15, an operation command 42 is outputted in the fourth step, and the operation is returned to the normal control.

Abstract: PURPOSE:To simultaneously improve a phase margine and a slice level margine based on a reading signal from a magnetic head by connecting waveform equalizing circuits having respectively different attenuation factors to the prestages of a limiter circuit and a gate generating circuit. CONSTITUTION:A reading signal from a magnetic head is respectively applied to the waveform equalizing circuits 11, 15 and the signal equalized by the circuit 11 is differentiated by a differentiation circuit 12 so that a peak position is converted into a zero crossing point of a differentiated waveform and the output of the circuit is discriminated by a data discriminating circuit 17 through a low-pass filter 13 and a limiter circuit 14. On the other hand, the equalized signal from the circuit 15 is inputted to a gate generating circuit 16 through a low-pass filter 13 and sent to the circuit 17. In this case, the waveform equalizing effects of the circuits 11, 15 are different from each other and the attenuation factors are also different. In a phase margine system based on the waveform equalizing circuits, the attenuation factors are set up so that the sum of an S/N jitter value and a pattern peak shifting value is minimized. In a slice level margine system, the attenuation factors are set up so that the sum of voltage dropping rates due to S/N ratios is minimized.

IPC: G06T1/00
Filed: 1992-02-13
Abstract: PURPOSE:To shorten the positioning time by changing the viewfield magnification of a bonding position recognizing camera while feeding a lead frame to obtain the position error of the tip of the lead frame and to correct the position of the lead frame at a high speed. CONSTITUTION:A lead frame is supplied to a wire bonding stage in the precedent process. Thus, a wire bonder changes the magnifying power of a camera to a low magnifying power image from a high magnifying power image and fetches the images from the bonding stage. Then the tip position of the lead frame is detected on the bonding stage based on the lead frame tip image information that is previously taught for decision of the presence or absence of the tip of the lead frame. If the tip position of the lead frame is detected, the error is calculated between the prescribed position of the frame tip and the actual tip position of the frame and this error is indicated 105 to a feeder. Then the feeder feeds the lead frame by an instructed extent to complete the positioning of the frame tip. Then the wire bonder changes the magnifying power of the camera and processes the images based on the image information.
