Title: Picture quality correction circuit
Inventor: HASEGAWA KOJI
IPC: H04N5/208
Filed: 1986-07-18
Abstract: PURPOSE:To prevent malfunction such as synchornization detection or synchronization separation by detecting a black level of an input video signal so as to eliminate a picture quality correction signal component being at a black level or below except the synchronizing period. CONSTITUTION:A capacitor 1, a diode 2 and a reference power supply 3 clamp a video input signal at the synchronization tip level and a refernece power supply 4 sets a standard video input signal to a same level as the synchronization amplitude level. A diode 5 and a resistor 6 give a reference potential of a black level of a balck level detection circuit essentially comprising an operational amplfier 7, and when the input video signal level is the black level or over, the black level detection circuit gives a low potential to a base of a transistor (TR) 8, which is conducted and when the input video signal level is the black level or below, the TR 8 is turned off. The TR 8 and the diode 9 are placed in an output stage of the picture quality correction circuit and limit the signal component being at the black level potential or below given by reference power supplies 3, 4 by the turning on/off of the TR 8.

The distribution of the quantity of light is decomposed through a fast Fourier transform circuit 48 into a spatial frequency and the distribution thereof is presented on a display 50. Distribution of the allowance for the spatial frequency components is also presented on the display 50.  The position of the lens array 4 in the X direction is adjusted with respect to the light emitting element array 2 by shifting the lens array 4 from the light emitting element array 2 in the direction (X direction) perpendicular to both the direction of the optical axis of lens (Z direction) and the array direction (Y direction) such that the spatial frequency components decrease on the low frequency side and increase on the high frequency side.

Title: Frame synchronization control circuit
Inventor: KOSUGE KOJI
IPC: H04L7/08
Filed: 1995-06-14
Abstract: PURPOSE: To keep an error between reception and transmission timing within a permissible deviation for a long time even when an oscillation circuit with a low stability is in use by following the phase of a reception frame timing signal with the phase of a recovery frame timing. CONSTITUTION: An oscillated frequency of an oscillation circuit 1 is frequency- divided by a variable frequency divider circuit 2, the result is used for a reception timing signal and it is fed to a frame timing recovery circuit 3. When the circuit 1 has low stability, a deviation is produced between a recovery and a reception frame timing with the elapse of time. An error detection circuit 4 detests a phase error between a recovery frame timing signal being an output of the circuit 3 and a reception frame timing signal being an output of the circuit 2 receiving the reception signal for each prescribed time based on a recovered frame timing signal, an averaging circuit 5 processes the phase error into an error timewise mean value, which is given to a frequency division ratio control circuit 6.  Then the circuit 6 applies feedback control to a frequency division ratio of the circuit 2 to allow the reception frame timing to follow the recovery frame timing.

Title: Forged piston for disc brake
Inventor: KURATA MASAYUKI
IPC: F16D65/18
Filed: 1980-12-03
Abstract: PURPOSE:To prevent reduction of the thickness of the part of a forged piston for a disc brake into which a dust protective boot end edge is engaged, by expanding the  part of a cylinder with a bottom which is at a slight distance from its open end  diametrically inwards by rolling. CONSTITUTION:Being pressed on the outer circumference of a forged cylinder 24, at a distancel from its open end surface 30, a rolling roll 25 is revolved about an axis 31 of the cylinder 24 to dent it diametrically inwards in order to form a concavity 29. On the other hand, a roll 26 which has a fulcrum axis 28 crossing the axis 31 at a small angle is pressed on the inner circumference of the cylinder 24 in order to prevent reduction of the diameter of the opening 30. Moreover, the concavity 29 is cut to form a concave groove 29a to engage with a dust protective boot. Then, these surfaces are plated with chromium to form a hollow piston. Thereby, a hollow piston having a uniform thickness and excellent corrosion and wear resistances can be readily obtained without the need for, specially, heat treatment.

Title: Inference system using rule relation
Inventor: NITTA TORU
IPC: G06F9/44
Filed: 1988-07-08
Abstract: PURPOSE:To perform the inference at a high speed by preparing a relation node and a relation deciding means and flowing a token based on the relation of the satisfaction of a rule condition part. CONSTITUTION:When a token is detected, an inference means 1 takes the token out of a knowledge base 5. Then the node to which the token flows via the means 1 is set at the node having the highest level in an inference network 2. The means 1 checks whether the node to which the token flows is presently coincident with a relation node 4 or not. If not, the means 1 performs a process proper to said node. If so, a relation deciding means 3 decides whether the flow of the token is needed or not based on the relation of the satisfaction of a rule condition part. If so, the means 3 sets the relevant node to one of those under the control of the node 4 and performs its processing. Thus the inference is carried out at a high speed.

Inventor: NAKATANI TORU
IPC: B65H3/56
Filed: 1985-08-02
Abstract: PURPOSE:To automatically feed a necessary kind of a seed bag and a necessary quantity of seed bags according to an order, by a method wherein rotary contact type seed bag feeing tools are mounted in series to the under side of a case train in a manner to be positioned facing their respective stock cases. CONSTITUTION:When the details of an order are inputted to a personal computer, according to the input, for example, a group A of motors 26 are run for a given time until the feed of ten bags is completed, a group B of motors 26 are run until the feed of five bags is completed, and a group D of motors 26 are run for a given time until the feed of three bags is completed. Thus, along with the rotation, common shaft 23 and 33 for all the groups A, B, and D are run, and this results in rotation of lower rolls 31 of all the groups A, B, and D. But, in a seed bag outgoing means 2, only clutches 24 in each stage and address are simultaneously turned ON, and thus, rotation is selectively effected to feed a seed bag. This, when runnings are respectively completed, causes return of each of the selected clutches 24 to an OFF-state.

Abstract: PURPOSE:To remove bittern component and acid component extremely easily from a citrus fruit juice, and to obtain fruit juice having high commercial value, by placing a bittern-removing column packed with a synthetic adsorption resin and an acid-reducing column packed with an ion-exchange resin in series. CONSTITUTION:The raw fruit juice stored in the storage tank 1 is transferred through the filter 3 to the bittern-removing column 4 by the pump 2, and the bittern component is removed by the synthetic adsorption resin 5 filled in the column. The rate of removal can be controlled arbitrarily by the passing rate of the liquid and the amount of the resin packed in the column. The fruit juice containing properly decreased bittern components is stored temporarily in the intermediate tank 20 and sent to the acid-reducing column 23 to effect the reduction of acid content by an anion exchange resin. The rate of removal of the acid component can be controlled arbitrarily by the passing rate of the liquid and the amount of the resin packed in the column. The fruit juice containing properly decreased bittern component and acid component is treated with the cyclone 27 to separate and remove solid component, passed through the filter 28 to remove the remaining solid component and taken out of the apparatus as the final product.
