Title: Exposure device for hologram
Inventor: ISHIKAWA TOMOHISA
IPC: G03H1/04
Filed: 1991-06-20
Abstract: PURPOSE:To provide the device which exposes the hologram of high display quality without generating any interference fringes even as to a hologram which has at least a >=40 deg. incidence angle or reproduction angle in reproduction. CONSTITUTION:This exposure device performs exposure with two beams by irradiating a photosensitive material 1 with light whose optical path from a laser beam source 4 with coherent length C to the photosensitive material and laser beam whose optical path up to the photosensitive material is N. A transparent plate 3 which is >=C.costheta'/2 when M>=N or >=costheta'.[C-(M-N)]/2 when M<N, where theta' is the angle of refraction of the laser beam with the optical path M on the photosensitive material 1, is laminated on the opposite side of the photosensitive material 3 from the incidence side.

Title: System for detecting fault in i interface circuit
Inventor: YAMAZAKI HIROSHI
IPC: H04L12/26
Filed: 1989-06-12
Abstract: PURPOSE:To execute fault detection with a simple circuit configuration by preventing a test signal to be inputted from being folded when a feeding voltage is out of a regular range. CONSTITUTION:When a feeding circuit 1 is abnormal and a voltage is lowered less than the Zener voltage of a Zener diode D1, a current does not flow to the Zener diode D1. Then, the light emission of a light emitting diode D2 in a photocoupler 31 is turned OFF and a transistor Q1 is turned OFF. Accordingly, since the input of an inverter 32 is set in the state of an H level through a resistor R2, the output of the level state is sent from this resistor and an AND gate 41 is turned OFF. Thus, even when a test control signal is sent from a control circuit 12 to a folding circuit 21, the signal is blocked by the AND gate 41 and test data can not be folded to an exchange (not shown in a figure). Thus, the fault detection can be executed with the simple circuit configuration.

IPC: H01L21/28
Filed: 1987-06-17
Abstract: PURPOSE:To contrive improvement in junction characteristics by a method wherein, before a high density impurity introduction layer is formed, a silicide film is formed, and impurities are introduced in such a manner that crystal defects caused by ion implantation will not be left. CONSTITUTION:A metal 4 is deposited on the whole surface of an Si substrate 1, a heat treatment is conducted at a low temperature, and a silicide film 5 containing metal more than a stoichiometric composition is formed. Then, after a non-reaction metal has been removed by wet-etching, an impurity doping ion-implanting operation is conducted, the implanted ions are activated by conducting a heat treatment at a high temperature, and the silicide film is converted into the state of stoichiometric composition at the same time. At this time, the damaged layer, formed by ion-implantation, located directly under the interface of the silicide film and the Si substrate disappears. As a result, a diffusion layer having excellent junction characteristics can be formed.
