Title: Optical element
Inventor: AOYAMA SHIGERU
IPC: G02B1/115
Filed: 1989-02-28
Abstract: PURPOSE:To make a grating difficult to be damaged and to relax expansion and contraction of the grating due to the change of circumstances by sticking a transparent film harder than the grating to a grating formation part. CONSTITUTION:A transparent film 4 harder than a grating 3 is stuck to the formation part of this grating 3. With respect to a Fresnel lens 1, the grating 3 made of a synthetic resin (like a resin hardened by ultraviolet rays) patterned to concentric circles is formed on one face of a square transparent substrate 2 by sticking, and a transparent film 4 is stuck to all of the surface of the formation part of the grating 3 on the transparent substrate 2. Thus, since the damage of the grating 3 is prevented and the transparent film 4 itself protecting the grating is difficult to damage and expansion and contraction of the grating 3 due to the change of circumstances are relaxed, optical characteristics are stabilized by suppression of the change of the refractive index of the grating 3 or the like.

Title: Brightness unevenness correction circuit for crt
Inventor: ARAI CHIHARU
IPC: G09G1/00
Filed: 1988-03-04
Abstract: PURPOSE: To uniform luminance by mutually adding the voltage values of parabolic waveforms outputted from 1st and 2nd voltage generation circuits based upon currents supplied to a horizontally deflected coil and a vertically deflected coil and supplying the added voltage to a 1st grid. CONSTITUTION: The voltage of a parabolic waveform which is boosted in accordance with approach to the peripheral part of a screen is generated synchronously with horizontal deflection based upon a current supplied from the 1st voltage generation circuit 1 to the horizontally deflected coil L1. The voltage values of parabolic waveforms outputted from the 1st and 2nd voltage generation circuits 1, 2 are mutually added by an addition circuit 3 and the added voltage is supplied to the 1st grid G1. Consequently the unevenness of luminance on a CRT can be corrected without deviating the position of a beam on the screen from the phase of voltage of the parabolic waveform and luminance can be uniformed on the whole screen.

Filed: 1986-03-07
Abstract: PURPOSE:To obtain a substantially shear-free, high-quality gel-like polymer continuously and easily in an excellent volume efficiency, by performing polymerization by using a specified straight tubular reactor whose diameter is enlarged just after the gelation zone. CONSTITUTION:A straight tubular reactor 5 is constructed by enlarging its diameter just after the gelation zone so that the sectional area on the outlet side of the body of a tube having a feed inlet 7 at the lower part and a polymer outlet 8 on the upper part may be larger than the sectional area on the feed inlet side and surrounding the outside of its body with a jacket 9 having an inlet 10 and an outlet 11 for cooling water. A feed material 1 which can give a gel-like polymer such as polyacrylic acid and a catalyst 2 such as a mixture of (NH4)2O2 with NaHSO3 are fed to and mixed in a mixing tank 3 in a N2 atmosphere. The resulting mixture is continuously sent to said reactor 5 by a pump 4, is subjected to polymerization by heating to 60+ or -3 deg.C and is allowed to ascend through the inside of the tube without being sheared because it reaches the area of an enlarged diameter soon after gelation occurs. The gel-like polymer after polymerization is cut with a cutter 12 to a desired size to obtain the purpose polymer continuously from a discharge outlet 13.

Title: Heat-sensitive bar code label printer
Inventor: HARAGA KOUICHI
IPC: B41J2/375
Filed: 1981-04-02
Abstract: PURPOSE:To prevent abnormal bar code printing by generating an abnormality signal when any one of heat generating resistors is damaged detecting an energization state to heat generating resistors while a picture signal selection circuit is not operated in a heat-sensitive head. CONSTITUTION:Heat generating resistors 35 of a heat-sensitive head 8 are divided into several sets (3 in the drawing) of blocks COM 1-3 and a matrix wiring is arranged for a common electrode selection circuit 5 and a picture signal selection circuit 6. In the normal operation, some signals come during the timing as shown by the dotted line D-G when common electrode signals A-C are generated and the heat generating resistors are energized to print a bar code or a character. Immediately after the generation of the signals A-C, a pulseIis generated from a pulse generation circuit 10 before the generation of signals D-G. At this point, if the heat generating resistors 35 are all normal, the inputs to a gate 45 are the H level while the output thereof is the L level. If any one of the resistors is damaged, one of the inputs goes to the L level while the outputs of the gate 45 go to the H level.

Title: Magnetic head manufacturing device
Inventor: OSATO TAKESHI
IPC: G11B5/127
Filed: 1987-03-06
Abstract: PURPOSE:To prevent deterioration in the characteristic by setting the incidence angle of magnetic metal particles at the time of film forming so that the angle of the particle-flow to the flat part of a ferrite-piece surface and the angle of the flow to the part angled at a certain angle of said surface come approximately equal to each other. CONSTITUTION:In the upper surface finished flat of the ferrite piece 1 from which a magnetic core half-body 4 is cut out, a groove 2 whose section in the direction of the width of the body 4 has slant sides in a certain angle is formed. The inner side surface 2a which is said slant side of the groove 2 comes to be a film forming surface 5a, hence the inclination angle theta1 of the inner surface 2a to the flat upper surface 1a of the piece 1 comes to be correspondent to the inclination angle theta1 of the film forming surface 5a to a magnetic gap 3. A thin film 3 is formed on the entire upper surface of the piece 1 by means of vacuum thin film forming method, at which time, the direction of incidence N of the magnetic metal particles is set at an inclination angle theta2 (theta2approx.=1/2theta1) against the upper surface 1a of the piece 1. This provides that the incidence angle theta2' of the direction N to the inner surface 2a comes to be approximately equal to said incidence angle theta2 to the upper surface 1a, such problems as cracking of the piece 1, cracking of a welded glass 7, or the degrading of head- characteristic.

Title: Semiconductor converter
Inventor: YABUNO TAICHIROU
IPC: H05K7/20
Filed: 1980-04-18
Abstract: PURPOSE:To restrain the rise in temperature of the central stages of piled cooling bodies and obtain a semiconductor converter of excellent cooling performance by making the projecting length of the heat-shielding plates in the central stages longer than that of those in both end stages. CONSTITUTION:Because the projecting length of heat-shielding plates 26 and 27, on the semiconductor-mounting side, is made longer than that of the others, air streams C and D passing through cooling bodies 15 and 16 include larger amounts of cold air, and also the effect of the rise in temperature resulting from the radiation by respective lower stages is avoided. Moreover, owing to a baffle plate 35, it is made difficult for the cold air flowing in from a ventilating hole 37 to flow through the cubicle central portion. By said constitution, the cooling temperature in each stage of the piled cooling bodies is uniformed, so that excellent cooling performance can be obtained.

Title: Coil spring
Inventor: HONDA AKIHIRO
IPC: F16F1/04
Filed: 1988-03-04
Abstract: PURPOSE:To decrease the closed height and the weight of a coil spring, by forming the sectional form of a spring element wire so as to be a semicircle expressed with a specific equation in the outer diameter side and a form expressed with a specific equation including its major axis and minor axis in the inner diameter side. CONSTITUTION:When the sectional form of a spring element wire 2 used in a coil spring 1 is mathematically expressed with x, y coordinates, the part situated in the outer diameter side of the coil (a part through G, H, I) is a semicircle having radius b expressed with the equation I. On the other hand the part situated in the inner diameter side of the coil (a part through G, J, I) is expressed with the equation II non-circular form. In this case the major axis is a and the minor axis is b. And the value of alpha is set in the range 2.1-2.4. Hereby the part in the inner diameter side, particularly the part with angular range + or -30 degree against the major axis a is compensated in thickness and the stress of this part is restrained to become high. As the result, the stress is uniformalized, and the closed height and the weight of the coil spring can be decreased.
