Abstract: PURPOSE:To offer a small-sized optical fiber amplifier whose adjustment and assembly are facilitated by integrally constituting a polarized light beam splitter in contact with the orthogonal surface of a transparent block and an interference film filter in contact with the inclined surface of the block respectively. CONSTITUTION:The transparent block 20 has the orthogonal surface 21 orthogonally crossed with an optical path on an incident side and the titled surface 22 on an exiting side. The polarized light beam splitter 12 is provided in contact with the orthogonal surface 21 of the transparent block 20 and the interference film filter 13 is provided in contact with the inclined surface 22. 1st and 2nd incident light beams having 1st wavelength are multiplexed by the beam splitter 12, made incident from the orthogonal surface 21 of the block 20, transmitted through the interference film filter from the inclined surface 22 and projected to be made incident on a fiber for amplifying light 11. Meanwhile, incident light having 2nd wavelength is made incident on the interference film filter 13 from a direction opposite to the incident light having the 1st wavelength and reflected to be made incident on the fiber for amplifying light 11 in the same way. When the incident light having the 1st wavelength is taken as exciting light and the incident light having the 2nd wavelength is taken as signal light, the signal light which is the incident light having the 2nd wavelength is amplified by the fiber for amplifying light 11.

Title: Electromagnetically driven shutter in camera
Inventor: OGIWARA MASUO
IPC: F24F7/10
Filed: 1984-06-25
Abstract: PURPOSE:To simplify mechanism and to permit easy handling by driving all the operations for focusing and exposure adjustment by means of a single electromagnetic driving member. CONSTITUTION:A stop motor 3 is turned and a driving plate 1 and an interlocking plate 2 are run toward the right when a release member is pushed down. An excited electromagnet 7e attracts simultaneously an electromagnet 7c and holds a focusing control lever 7 in the position where said lever does not contact with a detaining tooth part 2c. A light emitting element 6a irradiates impulsive light toward a subject at the arm end of a scanning lever 6. On the other hand, a bisected sensor 8 detects the impulsive light of the element 6a as the light reflected from the subject and outputs a focusing signal at the point of the time when the outputs from the two sensors coincide. The result of the measurement is displayed in a finder and the conduction of electricity to the electromagnet 7e is interrupted. The lever 7 released from the attraction is turned toward the right by the energizing force of the spring 7a to engage the claw 7d with the part 2c, thereby stopping the running of the plate 2. A distance ring 9 is further detained via a pin 2d to stop a photographing lens in the focusing position.

Title: Liquid crystal display device
Inventor: OTANI AKINARI
IPC: G09G3/36
Filed: 1991-06-03
Abstract: PURPOSE:To provide the high-brightness and high-quality liquid crystal display device capable of displaying a half-tone with fine gradations by controlling a signal supplied to a liquid crystal panel, shortening an image update period and reducing the discharge of a liquid crystal cell, and reducing brightness unevenness between an upper and a lower part on a screen and differences in brightness between odd-numbered and even-numbered lines. CONSTITUTION:The signal supplied to the liquid crystal cell is divided into a display signal Vs and a brightness signal Vb, which are supplied alternately in each signal update period Tr. At this time, the brightness signal Vb with saw-tooth waveform which is large at the large-discharge part of the liquid crystal cell and small at the small-discharge part is used. When a period wherein the display signal Vs is updated is the signal update period Tr, the image update period of the liquid crystal cell is reduced to a half as long as before, the discharge period of charges is shortened to a half, and a decrease in brightness is drastically reduced. Consequently, the brightness differences between upper and lower parts on the screen, and odd-numbered and even- numbered lines are reduced and the brightness unevenness between the upper and lower parts on the screen and the differences in brightness between the odd-numbered and even-numbered lines are drastically reduced.

Abstract: PURPOSE:To constitute a neuro chip without adding a sigmoid function computing element by setting the light-emitting characteristic of light emission elements to be a threshold functional one and feeding back the output of light-receiving elements corresponding to the light emission elements to the light emission elements. CONSTITUTION:A light emission element part 3 containing plural stripe-formed light emission elements 2, the optical shutter array 4 of a matrix array-form and a light-receiving element part 6 containing stripe-formed light receiving elements 5 extending in a direction perpendicular to the extending direction of the light emission elements 2 are sequentially laminated. Respective stripe- formed light-receiving elements 5 consist of photodiodes and they are connected to power sources E1-E4 through resistances R1-R4, whereby an inverse bias is impressed. Since the band gap of the semiconductor of a collector layer 23 is made larger than the band gap of a base layer 22 in the light emission elements 2, emitted light is coupled again in the base area 22.

Title: Waveform shaping device
Inventor: SUZUKI AKIRA
IPC: H04L25/03
Filed: 1984-06-26
Abstract: PURPOSE:To attain the waveform shaping of a synchronizing signal by providing a rectifier so as to change the comparison level in response to the level change in the input television synchronizing signal. CONSTITUTION:The television synchronizing signal fed to a terminal 1 is amplified by an amplifier 2 and applied to one input terminal of a comparator 3 and rectifier 6. The rectifier 6 has a rectifying function to detect and hold the peak value of this synchronizing signal and a function to control the range of change in the rectified output signal and the DC bias. That is, the DC voltage changed in response to the level change in this synchronizing signal is obtained. Thus, when the level of this synchronizing signal is changed from (a) to a', the comparison signal is set so as to be changed from (b) to b'. Thus, the pulse width change and phase change due to the synchronizing signal and level change are less at an output terminal 5 as shown in (c) and the waveform shaping is conducted accurately.

Filed: 1992-04-23
Abstract: PURPOSE:To provide a covering material having a superior covering strength in which its reaction with baked product is low by a method wherein a surface of alumina substrate having a specified porosity is covered by a non-stabilized zirconia. CONSTITUTION:In the case that a functional ceramics represented by a ceramics capacitor is baked at a high temperature, a minute or porous refractory material such as alumina, mullite, zirconia and magnesia is used as a baking jig. As a substrate for the baking jig, alumina having porosity of about 20 to 85% is used in such a manner that the functional ceramics may not react on the baking jig at a high temperature, and the surface of the alumina substrate is processed to be covered with non-stabilized zirconia covering (a layer thickness of 30 to 700mum). With such an arrangement, since a reaction between the baking jig and the baked product is made quite low and the substrate is of porous material, an adhering power between the substrate and the covering layer is increased and the covering layer does not show any cracks or peelings during its use over a long period of time.
