Title: Down-edge detection circuit using josephson junction
Inventor: HIDAKA MUTSUO
IPC: H03K5/00
Filed: 1985-05-17
Abstract: PURPOSE:To obtain a down-edge detection circuit with less area by giving a DC current to one of two inputs of a gate of a Josephson element and giving a signal in opposite direction to that of the said DC current to the other and injecting a gate current while it is retarded to the signal. CONSTITUTION:A DC current IDC is injected to a gate 21 using a Josephson junction from the 1st input line 23 and this state is shown in point 31. When a signal current Is is injected from the 2nd input line 24, since the direction is opposite, the state is transited to a point 32. The gate current Ig is injected with a delay from the gate current path 22 and the state goes to a point 33. When the signal current Is falls, the state moves to a point 34, but since this state is at the outside of the superconduction state of the threshold characteristic of the gate 21, the gate 21 reaches the voltage state and the trailing of the signal current Is is detected.

Abstract: PURPOSE:To provide a Fresnel lens of excellent light converging quality by constituting a rugged part which is dependent on the wavelength of the incident light and corresponds to the phase modulation of the lens of the specified material. CONSTITUTION:A rugged part 2 corresponding to the phase modulation of a lens with serrated section is provided on the surface of the Si crystal 1. The depth (t) of the groove of this rugged part 2 is set so as to meet the relationship t=lambda/(n-1) by using the refractive index (n) of the substance constituting the lens and the wavelength lambda of the incident light to maximize the light converging efficiency of the lens. The refractive index of the near-infrared and transparent InP is n=3.3, and the semi-conductor laser beam of lambda=1.55mum is used as the incident light, and the depth of the groove t=0.67mum. As a result, the quantity of the unwanted multiply reflected light to be generated at the vertical part of the rugged part 2 is greatly reduced, the reduction of the diffraction efficiency attributed to this multiply reflected light is prevented, and a diffraction tpe Fresnel lens excellent in the light-converging efficiency can be easily realized.

Title: Logical circuit for integrated circuit
Inventor: TAKI YOSHIHARU
IPC: H03K19/003
Filed: 1983-06-13
Abstract: PURPOSE:To stabilize the simultaneous switching of output terminal signals of a large-scale IC by obtaining a logic between the signal supplied from an input terminal of an IC and the switch control signal of the output terminal signal. CONSTITUTION:A clock signal C1 is supplied in common to latch FF1 and 2, and data signals D1 and D2 are supplied to terminals D of the FF1 and 2 respectively. The gate signals G1 and G2 of tri-state gate groups 3 and 4 are delivered from the FF1 and 2 to perform the simultaneous switching of output terminal signals 5 and 6 of an IC. An input terminal 12 is provided to this IC, and the timing signal D3 supplied from the terminal 12 and the output signal Q of the FF1 are supplied to an AND circuit 13. The signals D1 and D2 are supplied at a time, and the FF1 and 2 deliver them at a time. However an AND 13 is obtained between the output Q of the FF1 and the signal D3, and the signal G1 is delivered. Therefore a time difference T is produced between the signals G1 and G2, and no simultaneous switching of signals is carried out between output terminal groups 5 and 6. Thus the simultaneous switching frequency is reduced to ensure a stable switching operation.

Title: Liquid crystal display element
Inventor: ISHIKAWA MASAHITO
IPC: G02F1/1333
Filed: 1993-04-30
Abstract: PURPOSE:To lower a driving voltage and to improve response speed and after-images by mixing a nematic liquid crystal material and smectic liquid crystal material which do not dissolve each other, thereby obtaining a light control phase. CONSTITUTION:A liquid crystal mixture composed of the liquid crystal 9 exhibiting a nematic phase and the liquid crystal 8 exhibiting the smectic A phase which do not dissolve each other is clamped between substrates 6 and 7. This mixture orients uniformly toward an orientation direction 4. The liquid crystal 8 exhibiting the smectic A phase is not capable of responding with an electric field when a voltage is applied between electrodes 2 in such a case and, therefore, only the liquid crystal 9 exhibiting the nematic phase responds to the electric field. Since the nematic liquid crystal has anisotropy of refractive index, the refractive index of the nematic liquid crystal changes to the refractive index different from the refractive index of the smectic A liquid crystal when the liquid crystal molecules incline with the electric field. The light transmitted through the LCD is then scattered light. The molecular arrangement rapidly restores the state not applied with the voltage by the orientation regulating force of both of the smectic liquid crystal and the oriented layer when the voltage between the electrodes 2 is removed.
