IPC: C09K19/40
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain an excellent gradation display characteristic by forming a distribution on a switching threshold value of a liquid crystal according to the distribution of a tilt angle of a liquid crystal layer. SOLUTION: The liquid crystal 13 is a ferroelectric liquid crystal that a liquid crystal molecule is a non-spiral oriented state and shows at least two optical stable states, and when its tilt angle is defined as Θ, and an apparent tilt angle as θa, to have the relation of Θ>θa>Θ/2 is preferred.

Title: Electrophotographic receptor
Inventor: ENOMOTO KAZUHIRO
IPC: G03G5/14
Filed: 1981-07-24
Abstract: PURPOSE:To obtain an electrophotographic receptor, capable of forming always sharp copied images after repeated uses, low in light fatigue, and adapted to multiple copying, by forming a layer containing a UV absorbing compound on a conductive substrate. CONSTITUTION:In a photoreceptor intended for repeated uses, when an organic photoconductor is used for a charge carrier substance, the photoconductor inevitably undergoes long-time irradiation of UV region rays, resulting in undergoing adverse effects, such as deterioration of image density and increase of fog.  These adverse effects are prevented by providing a layer 3 containing a UV absorber on a conductive substrate 4, and further laminating a photosensitive layer  2 on the layer 3. As the UV absorber used for this invention, the known absorber, and diesters of resorcinol, benzotriazols, heterocyclic benzoates, 1-amino- 4-cyano-1,8- butadiene, etc. are embodied. These absorbers can be used alone, but  preferably used in the matrix of acrylic resin or the like.

Title: Picture data compressing system
Inventor: YOSHIDA SHIGERU
IPC: H04N7/12
Filed: 1988-05-13
Abstract: PURPOSE:To efficiently transfer picture data with high quality by holding the resolution of an edge by using the block encoding at the contour part of a picture and holding the gradation by using vector quantization at an area where the gradation change is smooth. CONSTITUTION:When the picture element data for a block are inputted to a terminal 1, a maximum level Lmax and a minimum level Lmin of the gradation are obtained by a maximum minimum detecting circuit 10 and sent to La and Lb arithmetic circuits 11. At the circuit 11, from expressions I and II shown next, a median La and a difference value Ld are obtained. Namely, the signal level of the picture is between black and white, an consequently, both Lmax and Lmin are surely between black and white. Then, for an expression I, La=(Lmax+Lmin)/2 to show the medium is used and for an expression II, Ld=(Lmax-Lmin)/2 to show the difference value is used. Next, the difference value Ld out of these is given to a mode detecting circuit 20, compared with the encoding parameter, encoded by a binary block encoder 26, selected by a multiplexer 27 and a compressing signal is outputted from a terminal 2.

Title: Thyristor valve
Inventor: KOBAYASHI ATSUO
IPC: H02M1/08
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a thyristor valve in which a thyristor LTT(light trigger thyristor) is protected against breakdown upon application of a forward overvoltage exceeding the breakdown voltage during a transient interval after interruption of current supply from the thyristor LTT before recovery of the forward breakdown voltage to a rated level. SOLUTION: A second gate pulse is delivered to a thyristor LTT during a transient interval after the thyristor current is interrupted by turning the thyristor LTT on with a first gate pulse before the forward breakdown voltage is recovered to a rated level. Since the gate part can have the lowest part of the forward breakdown voltage in the junction face during the transient interval, the thyristor LTT is turned on starting from the gate part, without fail, upon application of the forward breakdown voltage. Consequently, carriers are increased through amplification of the gate current and a transition is made to conducting state in safety thus protecting the thyristor LTT against breakdown.

Title: Manufacture of forging made of al alloy
Inventor: SAKONO OSAMU
IPC: C22F1/04
Filed: 1989-05-09
Abstract: PURPOSE:To obtain the forgings free from the generation of cracks and to reduce the heat treating time therefor by forging Al alloy forging stock after subjected to solution treatment and executing aging treatment. CONSTITUTION:Forging stock made of Al alloy is subjected to solution treatment and is thereafter forged. The forgings are subjected to aging treatment. Eutectic Si acicular compounds crystallized in the metallic structure before subjected to forging are exposed to the high temp. atmosphere for long time and are completely parted and spheroidized by solution treatment. Furthermore, the compounds are uniformly dispersed into the metallic structure without segregated. Moreover, since heat treatment which serves for forging is substituted by solution treatment, there is no need for executing heat treatment independently. Thus, the improvement of productive efficiency and energy-saving can be attained.

Title: Vertical oscillation circuit
Inventor: NOMURA SUNAO
IPC: H03K4/90
Filed: 1988-05-12
Abstract: PURPOSE:To obtain a required oscillated frequency by making the forced synchronization of a vertical synchronizing signal possible even if a difference between a free oscillated frequency and the vertical frequency is large. CONSTITUTION:The oscillated frequency is made coincident with the vertical frequency by using forced synchronization by a vertical synchronizing signal. The forced synchronization is implemented by turning on a transistor(TR) Q11 by means of a synchronizing signal to bring the voltage of an oscillation capacitor 3 into a base bias (VH) rapidly, and then the state of TRs Q1, Q2 is inverted regardless of the timing when the synchronizing signal is introduced. Then even if the difference between the difference between a free oscillated frequency and the vertical frequency is large and the vertical frequency is higher than the frequency able to be locked and decided in the inside of the IC, the synchronization is attained and the circuit is oscillated by the vertical frequency. Thus, the required oscillated frequency is obtained.
