IPC: C09J121/02
Filed: 1980-03-28
Abstract: PURPOSE: To provide a synthetic rubber latex adhesive which has structural viscosity characteristics similar to Newtonian structural viscosity and is thicknened, by adding vinyl acetate emulsion and polyvinyl alcohol to a synthetic rubber latex.  
     CONSTITUTION: 5W15pts.wt. (on a solid content of synthetic rubber latex) vinyl acetate emulsion is added to a synthetic rubber latex to modify a structural viscosity, which the synthetic rubber latex originally possesses, to a basic structural viscosity similar to Newtonian structural viscosity. Further, 0.2W2pts.wt. (on a solid content of the synthetic rubber latex) polyvinyl alcohol is added to the above mixture. to thicken is. When the amount of the vinyl acetate emulsion is less than 5pts.wt., an effect on an improvement in the structural viscosity can not be obtd. When the amount is more than 15pts.wt., initial rise of bond performance is lowered. When the amount of the polyvinyl alcohol is less than 0.2pts.wt., thickening effect is low. When the amount is more than 2pts.wt., the viscosity is too high and initial rise of bond performance is remarkably lowered. Thus, such an amount is not preferred.

Title: System for shortening access time of random access memory
Inventor: YUEI POO RIN
IPC: G06F11/10
Filed: 1977-04-08
Abstract: 1536103 Data storage system NCR CORP 29 March 1977 [29 April 1976] 13106/77 Heading G4A A random access store is connected to an output buffer which stores a word from the store and supplies the word to an output respectively in response to input and output clock signals from a clock generator which initiates the output clock signal before termination of the input clock signal. A check device checks the word in buffer for errors at the termination of the output clock signal.  The clock generator may be a counter driven by the clock of an associated processor, the clock of the store output bus, or a clock internal to the store. The store is such that on average data becomes available at a time 30 following initiation of an access at 25, with a variation between time 32 and normally 34 or abnormally even later. The buffer is clocked for input by signal # and for output by signal MGE as shown, the signals terminating together after time 34. Termination of the signals enables a gate receiving the output of a parity check circuit, an error signal from the gate generating a further output clock MGE at the next clock pulse rather than a complete new access cycle. The arrangement allows the store to provide an output at any time during output clock MGE and checks for errors at the end of that signal.

IPC: G11B20/12
Filed: 1981-03-19
Abstract: PURPOSE:To equalize components of n-number of stripe regions to the unit traverse quantity of a magnetic tape, by arranging n-number of pairs of magnetic heads, which scan n-number of stripe regions during one rotation of a rotating shaft, at intervals. CONSTITUTION:The rotation direction of a rotor 1 shown by an arrow B is inclined to the traverse direction of a magnetic tape 5 shown by an arrow A. Consequently, the first pair of magnetic heads 2-3 and 3-2 and the second pairs of magnetic heads 2-4 and 3-4 scan stripe regions S4 and S1 respectively, and magnetic heads scan stripe regions S2 and S3 during the rotation of the rotor 1 different from that for stripe regions S4 and S1. Thus, the magnetic coupling due to a leakage magnetic flux between magnetic heads is very small, and consequently, the crosstalk between recording and reproducing signals is suppressed to such degree that it can be ignored practically.

Title: Signal processing device
Inventor: HARA YOSHIHISA
IPC: G01S13/88
Filed: 1989-02-21
Abstract: PURPOSE:To enable detection of a hovering helicopter by counting a significance signal output of a signal detecting circuit in the direction of the frequency and by comparing a counted value thus obtained with a certain threshold value. CONSTITUTION:A Doppler frequency band of waves received from a hovering helicopter is much wider than the one of an ordinary target. This is caused by various Doppler frequencies generated according to angles of a rotating rotor. By detecting the expansion thereof, i.e. the expansion of in the direction of frequency of a signal detection output of a signal detecting circuit 4, the hovering helicopter can be discriminated. For this purpose, it is needed only to count the output of the detecting circuit 4, by a first counter 6, across a frequency range wherein the Doppler frequencies are considered to be present, and to compare a counted value thus obtained with a certain threshold value by a comparator 7. When the counter value is larger (smaller) than the threshold value, as the result, it means that said output expands (does not expand) in the direction of the frequency. Accordingly, the output is regarded as that of the hovering helicopter (the ordinary target) and a hovering helicopter detection signal 11 is made to be 1 (0).

Title: Thermal recorder
Inventor: KATSURAGI SHIGERU
IPC: B41J2/355
Filed: 1986-02-26
Abstract: PURPOSE:To scan with a high-speed clock signal for a continuous white signal part and enhance recording speed, by a method wherein recording enable signals serially inputted are outputted to driving elements in parallel by a controlling shift register, and the number of the recording enable signals not more than a power source capacity necessary for simultaneously driving all heat generating resistors are generated. CONSTITUTION:Recording enable signals (a) serially outputted from a recording enable signal generating means 8 in a controlling circuit 9 are transferred to a controlling shift register 5 by a clock signal (b), and outputs a1-an from the register 5 are inputted to gate circuits 4. For the period of time for which a recording signal c1ncn is black and recording is enabled by the recording enable signal a1-an, the gate circuit 4 drives a driving element 2 to supply an electric current from a power source 3 to a heat generating resistor 1. The recording enable signals (a) enable recording only for a period of time corresponding to the number of clock pulses for the number of the heat generating resistors not more than the capacity of the power source 3, and thereafter the signals (a) are transferred in the state of not enabling recording, until one line is completed. When a continuous white signal part of at least 3 bit is detected in the recording signals, the means 8 transfers the clock signal (b) at a higher speed until the next black bit is detected.

Title: Manufacture of device using variable transmission aperture
Inventor: CIRELLI RAYMOND ANDREW
IPC: G03F7/20
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To optimize the depth of focus of an exposure, by selecting the size of a plurality of apertures of a filter element and their transmittance which is variable within a prescribed range, based on a comparison made between an intensity profile of radioactive rays based on a mask pattern and an intensity profile of radioactive rays that have transmitted through the filter element. SOLUTION: A plurality of apertures of a filter element 20 each have such a transmittance as to change from about zero to about 100 percent with respect to radioactive rays. By combining intensity profiles with respect to the radioactive rays which have transmitted through each part of the element 20, an intensity profile of the element 20 is modelled, and the modelled intensity profile is compared with a desired intensity profile based on a pattern of a mask 30. When both do no coincide, any of the transmittance, location and shape of one or more apertures of the element 20 is altered. The above process is repeated until the intensity profile modelled from the element 20 coincides with the desired intensity profile.
