Title: Integrated semiconductor device
Inventor: OONO YASUO
IPC: G01R31/26
Filed: 1978-04-18
Abstract: PURPOSE: To measure easily the oscillation frequency of a high-speed oscillation circuit in an IC device, by forming a small-area NOR gate circuit in one together with the IC as a substitute for a buffer amplifier.  
     CONSTITUTION: A measured signal of a rectangular wave is inputted to terminal 1 of the NOR gate composed of transistors 6 and 7, and a rectangular wave of exactly the same frequency is inputted to terminal 2, so that the mean value of gate output 5 will be equal to half a voltage of the amplitude with the both in phase or to zero with the both out of phase. When both frequencies shift, gate output 5 varies gradually vibrating between half the maximum value and zero according to the shift in phase. The measured frequency can be found by supplying input 2 with a known frequency selected so that vibrations will stop. When the difference in frequency between input signals is a multiple of an odd number, gentle vibrations appear nearly at the frequencies, but it is required only to find a frequency giving the maximum amplitude at this time.

Title: Production of optical film element
Inventor: SEKIGUCHI TOSHISADA
IPC: G02B5/30
Filed: 1989-03-01
Abstract: PURPOSE:To produce an optical film element suitable for miniaturization and improvement of the precision by preparing a substrate consisting of materials soluble in a solvent to form the optical film on this substrate and adhering the optical member onto this optical film and dissolving the substrate in the solvent thereafter, instead of directly forming an optical film on an optical member. CONSTITUTION:A substrate 20 is prepared which consists of materials soluble in the solvent and is flat as the whole, and its one principal surface is finished into a specular face. A layer-built film 16 where optical materials of a film having a high refractive index and those having a low refractive index are alternately laminated is formed on this surface. An adhesive layer 18 is coated on a uniform film material part of the layer-built film 16, and optical members consisting of optically transparent materials, for example, plural prisms 10 are adhered. Thereafter, the whole of this structure body is immersed in a solvent 22 to dissolve the substrate 20. Thus, damages and cracks are prevented to efficiently produce many optical film elements, and optical films are free from heterogeneity, and especially, this method can cope with miniaturization and improvement of the precision of optical elements.

Filed: 1983-03-18
Abstract: PURPOSE:To reduce the generation of noise by a structure wherein each of a pair of gears is formed in a near circular truncated cone-shape as a whole by shifting each tooth positively at the upstream end and negatively at the downstream end in the direction of the component parallel to the gear axis of the pressing force generated by intermeshing helical gears with each other. CONSTITUTION:A drive side helical gear 1 provides with teeth 1a having right- handed helix angle beta and each tooth 1a is formed at its left end 1b by shifting positively or to the outside of the pitch circle while at its right end 1c by shifting negatively or to the inside of the pitch circle so as to realize a near circular truncated cone-shape as a whole.

Abstract: PROBLEM TO BE SOLVED: To generate a Bessel beam with large depth of a focus by making the light beam, projected from a light source means emitting a light beam with a cylindrical light intensity distribution, incident on an image formation optical system. SOLUTION: The light source means 12 which emits the light beam (laser beam) with the cylindrical light intensity distribution consists of, for example, a vertical oscillation type surface light emission laser (semiconductor laser) and generates the laser beam (light output) 11 having the cylindrical (doughnut- shaped) light intensity distribution.

Thus, the Bessel beam having the intensity distribution which is nearly in proportion to the square of a 0-order Bessel function of 1st class is generated in the interference area (Bessel beam area) 21.

Title: Decoder circuit
Inventor: ISOGAI HIDEAKI
IPC: G11C11/413
Filed: 1981-03-31
Abstract: PURPOSE:To reduce the power consumption and to improve the operating speed, by installing a switching means which drives output step transistors which are conductive only when selected for output logical operation circuits. CONSTITUTION:From input signals A0, A1, these signals and inverted signals are formed by two sets of input gates IG0, IG1, etc. When all of these signals A0, A1 are at high levels, etc., and a word line W0 is selected, a multiemitter transistor TW0 of a logical operation circuit is turned on and an npn transistor TSO for switching becomes conductive. Then, a diode D2 for clamping the level and an output step transistor TD0 connected to a resistance Ry2 for discharging are driven and an electric current flows through the line W0. On the other hand, even when transistors TW1- of a nonselection logical operation circuit are conductive, the flowing electric current is less or they do not become conductive, and, therefore, switching transistors TS1- do not become conductive. Therefore, the electric current flows through only the selected word line and the transistors TD0- quickly rise through the resistance Ry2, and thus, the power consumption is reduced and the operating speed is improved.

The resulted power semiconductor element 26 is fixed on a bed of a lead frame mounted to a dissipating plate. Accordingly, the emitter electrode comes to the same potential as that of the dissipating plate.
