The distance L between the intersection of the beams 11 and 22 on the scanning plane and the reflection surface of the mirror 6 is given by an approximate expression: L=(r/2) cos(ϕ/2). In the expression, (r) is the radius of the circumscribed circle of the mirror 6, and ϕ is an angle formed by the optical axis of a scanning lens 5 with the beam made incident on the mirror 6. Thus, the size of the mirror 6 does not get large even when plural light sources are arranged in parallel.

Title: Discharge detecting counter
Inventor: MIZOGUCHI HITOSHI
IPC: H01T15/00
Filed: 1977-10-07
Abstract: PURPOSE: To detect and count the discharge an impulse current and to make it possible to sufficiently endure the short-circuiting dynamic current by using a transformer which has proportional characteristics to the impulse current and which is adapted to be saturated for a system short-circuiting dynamic current.  
     CONSTITUTION: When a gas gap impulse discharge current flows as the primary current I 1  of a transformer 2, the resultant secondary current takes such a level as is determined by the winding ratio. Since, for the impulse current, the impedance of a capacitor 8 is selected a sufficiently low level in comparison with a parallel reactance 6, the capacitor 8 is charged to a sufficiently high voltage so that a detecting or counting device 9 is operated. In case, on the other hand, a short-circuiting dynamic current flows as the primary current, the impedance of the parallel reactace 6 is selected to a sufficiently low level in comparison with the capacitor 8 so that the secondary voltage is prevented from being raised and so that the secondary current I 2  take the shape of pulses as a result of saturation for the high current, thus preventing the burn-out due to the short-circuiting current

IPC: H01G4/12
Filed: 1989-05-12
Abstract: PURPOSE:To prevent generation of expansion of width on a low dielectric constant part after sintering, and also to prevent the growth of grains on the high dielectric constant part located in the vicinity of the low compositional rate part and to obtain a composition for insulating paste having an excellent insulating property by a method wherein the compositional ratio of a mixture or a compound containing Al2O3, SiO2 and Mn compound is specifically prescribed. CONSTITUTION:Among molded material 22, insulating paste 23 is coated on the front and the rear sides of the part to be used as a region B, and the layer of insulating paste 23 is formed. The composition of the insulating paste 23 is set as Al2O3 of 48 to 90mol%, SiO2 of 0 to 18mol% and Mn compound of 10 to 40mol%. By coating the composition for insulating paste, consisting of the above-mentioned compositional ratio, on the ceramic molded body before a primary sintering, the insulating paste is diffused into a substrate before the conduction of a primary sintering, the growth of grains on the part of coating is suppressed, and the expansion of a low dielectric constant part after sintering is also suppressed. As a result, the effective utilization of the ceramic molded body can be accomplished maintaining the area of a high dielectric constant part, and the generation of a signal leak and noise can be prevented.

Title: Magnetic head
Inventor: HAYASHI KAZUHIKO
IPC: G11B5/127
Filed: 1984-06-12
Abstract: PURPOSE:To improve the permeability of a magnetic head by providing an action gap formed to a conductive magnetic core with a nonmagnetic conductor and a means which flows a current to the magnetic core across the action gap. CONSTITUTION:A conductive magnetic core 7 is energized by a power supply 9, and a current (i) flows as shown by an arrow head along the magnetic path of the core 7 and across an action magnetic gap (g). Thus the uniaxial anisotropy is produced in the direction orthogonal to the current (i), i.e., the magnetic path of an artificial ring shape. Thus the permeability of the core 7 is improved at a high frequency band together with the reproduction sensitivity of a head. While the direction of the uniaxial anisotropy can be changed with control of the current value when the core 7 is energized as long as said anisotropy is previously provided to the core 7 in the prescribed direction, i.e., the circumferential direction of said artificial ring. This improves the reproduction sensitivity of the head at an optional frequency band.

Title: Hybrid ic
Inventor: KAGEYAMA SEIICHI
IPC: H01L23/02
Filed: 1985-06-03
Abstract: PURPOSE:To eliminate the need for plating by coating the outside of a metallic lid with a case made of a synthetic resin. CONSTITUTION:Since a case 4 made of a synthetic resin is fitted outside a metallic lid 3 and all of the outer circumferential surface of the metallic lid 3 are coated with the case 4 consisting of the synthetic resin, sections undesirable on a fine view, such as flaws, rust, etc. cannot be viewed from the outside even when these sections are generated on the surface of the metallic lid 3 in a molding process. Since moisture is also interrupted by the case 4, no rust is generated. Accordingly, various plating need not be executed onto the surface of the metallic lid 3, thus economizing cost corresponding to the unnecessity of plating.

Abstract: PURPOSE:To improve the extent of blowing capacity by making the sum total of areas of a circular blade outer surface smaller than a surface area of the impeller peripheral side of a multiblade blower, and setting the number of blades down to more than 45 pieces. CONSTITUTION:A permanent magnet 2 is installed in a main plate 1 of an impeller (b) and a stator 9 in a casing (a), respectively. The impeller (b) is made smaller in the sum total of outer surfaces of a circular blade 5 than a surface area of the peripheral side of the impeller (b), while the number of pieces of the blade 5 is set down to more than 45 pieces. With this constitution, numbers of the blade 5 short in circular length are installed whereby an effective flow is formed on the surface of the blade 5, so, work per blade gets off with smallness. Consequently, blowing capacity as a whole is thus improvable.
