Abstract: PROBLEM TO BE SOLVED: To obtain the subject new polymer solving a problem that the hydrophilicity and biodegradability of a conventional polymer are inferior, and useful as a hydrophilic cation polymer for polymer coagulants by including amide bonds in the main chain. SOLUTION: This polyamideamine comprises repeating units of formula I [R1 -R4 are each H, an alkyl, an aryl, etc.; (n) is an integer of >=2]. The polymer is obtained by hydrolyzing a vinylimidazoline polymer comprising repeating units of formula II. In order to rapidly carry out the reaction, the reaction system may be heated. The reaction is preferably performed under a basic condition to accelerate the reaction. The vinylimidazoline polymer comprising the units of formula II is obtained e.g. by adding acrylonitrile to ethylenediamine and subsequently reacting the obtained cyanoethylethylenediamine with 1,3- dimethylimidazolidinone in the presence of zinc acetate.

Abstract: PURPOSE:To shorten an average moving time of a magnetic head and to read out a bit of correct information by correcting a position of the magnetic head only at the time of the occurrence of a read error. CONSTITUTION:When a pulse signal (d) outputted form a read circuit 6 is error, a positioning correction signal (e) is sent from a host device to a positioning correction circuit 7, thereby outputting a positioning offset signal (f) to a motor control circuit 1 in order to shift the positioning position to a correcting position for moving forward and backward respectively. Then, the motor control circuit 1 outputs a driving signal (b), and consequently the magnetic head 4 is positioned. And, a read signal (c) in each individual correcting position is inputted to a level detection comparator circuit 8, and the level detection and the comparison of its result in height are carried out, and then a positioning correction directing signal (g) is outputted to the positioning correction circuit 7 so as to make a shift putted to the positioning correction circuit 7 so as to make a shift in the direction of a correction position decided as the high signal level so that the positioning correction circuit 7 outputs the positioning offset signal (f) to the motor control circuit 1. By this method, the average moving time of the magnetic head 4 is shortened, and the correct information can thus be read out.

Filed: 1991-07-03
Abstract: PURPOSE:To reduce the machining cost by shortening the machining time. CONSTITUTION:The array state of cutting points in the 1st row of a matrix is investigated; when the cutting points are arrayed between noncutting points like (P114)-(P118), new cutting points Pax, Pbx, and Pcx are set on the same column with the cutting point (P114) in the outward direction of the 1st row and after cutting points Pax, Pbx, and Pcx are cut in order, the cutting is performed up to the cutting point (P114)-(P118) in order. Consequently, although the cutting point (P114) increases in cutting area when cut directly, the cutting area is reduced by the area (Cax+Cbx+Ccx) of cutting of the cutting points Pax, Pbx, and Pcx by a cutter C, so the cutting load hardly increases. Consequently, the feed speed of the cutter C can be increased.

Abstract: PURPOSE:To vary the oscillating wavelength in a broad range, by forming a comb shaped electrode ultrasonic wave oscillator (IDT) on a light confining layer so that the pitches of the oscillator are different depending on positions, thereby making the oscillating frequency vary. CONSTITUTION:When an electric field of a frequency (f) is applied to an IDT10, an SAW is generated and proparated in the light emitting direction along a p type GaAs layer 3. Single mode vertical oscillation can be generated by the SAW. Laser light having a wavelength lambda shown by an expressionIis obtained, where LAMBDA is the wavelength of the SAW. When the frequency (f) of the applied electric field is varied, DELTAlambda is obtained by an expression II, where V is the propagating speed of the SAW. When the oscillating frequency of the IDT10 is varied by DELTAf, the oscillating wavelength can be varied by DELTAlambda. The pitches between the electrodes are different. With the frequencies f1-fn corresponding to the different wavelengths LAMBDA1-LAMBDAn of the SAW as the center, each frequency can be varied by DELTAf. The corresponding oscillating wavelength can be varied by DELTAlambda with lambda1-lambdan as the centers.
