Title: Production of polymer emulsion
Inventor: SUZUKI TADANOBU
IPC: C08F2/26
Filed: 1981-03-03
Abstract: PURPOSE: To produce the titled emulstion having good film-forming property and providing films excellent in water resistance, solvent resistance, transparency, blocking resistance, etc., by polymerizing an acid group-free vinyl monomer in the presence of a specified emulsifier.  
     CONSTITUTION: 75W30wt% acid group-free vinyl monomer[e.g., alkyl (meth) acrylate]is mixed with 25W70wt%, as an emulsifier, aqueous alkaline solution of a carboxyl group-containing polyolefin (e.g., Na salt of an ethylene/acrylic acid copolymer). The resulting mixture is emulsion-polymerized at 60W90°C for at least 2hr in an aqueous medium in the presence of a polymerization initiator (e.g., t-butyl hydroperoxide), a reducing agent (e.g., Na 2 SO 3 ) and an inert gas atmosphere and then aged at a temperature nearly equal to the polymerization temperature for a period of about below 20% of the polymerization time.

Title: Operating mode setting method for programmable controller
Inventor: YOSHIKAWA KAZUO
IPC: G05B19/05
Filed: 1992-02-17
Abstract: PURPOSE:To shorten the response processing time for operating mode change in response to reduction of the scan processing time by reading the operating mode indicated by an operating mode changeover switch synchronously with the scan processing. CONSTITUTION:A CPU 10 performs the first reading operation in a mode indicated by an operating mode changeover switch 60A and then checks the coincidence between the operating and stop modes of a work memory 70. If no coincidence is obtained between both modes, the change of the mode indication is decided and the reed mode is temporarily set end stored in a mode information storage area. Then the CPU 10 sets a counter at '0' and counts the continuous discordant frequency between the reading and setting modes. When this discordant frequency reaches a prescribed level, an operating change request flag is turned on and the change of modes is permitted. Then the CPU 10 checks whether an operating change request mode flag is turned on or off and carries on its executing procedure to perform other scan processing after confirming that the change of modes is not permitted.

IPC: G11B7/09
Filed: 1981-03-02
Abstract: PURPOSE:To increase the reliability of an error signal, by comparing and previous data stored in a memory in which output data of an A/D converter is stored, with present data from the A/D converter discriminate said data. CONSTITUTION:A comparison and discriminating circuit 19 performs a comparison between a present focus data DF1 and tracking data DT1 generated from A/D converters 15 and 16 and passed through delay circuits 20 and 21, and forecast data DF2 and DT2 to discriminate whether the present data are normal or not. If the level difference between the forecast data and the present data is a prescribed value or more and if the polarity is dissident, the present data is discriminated as being abnormal. Thus, the reliability of time difference signal can be increased, by checking the degree of the correlation between the forecast value and the present value.

Title: Ion injection unit
Inventor: SAKURAI TERUO
IPC: H01J37/317
Filed: 1978-03-16
Abstract: PURPOSE: To control the ion amount injected on the substrate, depending on the location on the substrate, with a simple constitution.  
     CONSTITUTION: To the triangle output wave of scanning poewer supply, amplitude, frequency or amplitude frequency modulation is made, and ion injection is made based on the scanning signal. In case of amplitude modulation, the waveform fed to the upper and lower deflection plates is unchanged for the repetitive period and the amplitude changes between +2 to -1 KV. Accordingly, the lower half of the substrate is at normal ion density and the upper half is about a half the ion density for the injection because of greater amplitude and the same period. With this method, only with the addition of a simple unit (modulation circuit), the ion density is controlled depending on the location on the substrate, to perform injection.

Title: Training signal generator
Inventor: KOKURYO GARO
IPC: H04B3/10
Filed: 1985-02-20
Abstract: PURPOSE:To improve the turn-around efficiency of the system by dividing a training signal into the first half and the latter half and sending the first half to a transmission line not via a filter of a training device. CONSTITUTION:When a transmission request signal is fed to a terminal 1, a training generation control section 2 throws a contact of a switching circuit 4 to the position (t) and drives training sequence generating circuits 3, 19 and a damping factor generating circuit 20. As a result, the training signal sent from the circuit 19 and the output signal of the circuit 20 are multiplied by a multiplier 21 and the signal of the first half of the training signal is generated from the multiplier 21. On the other hand, the circuit 3 generates the training signal after a delay time tau in the training signal generating period. Thus, the first half signal in the training signal is outputted directly not via the filter during the period corresponding to the delay time tau and then the normal training signal through LPFs 6, 7, that is, the latter half signal is sent.
