IPC: G06K9/68
Filed: 1988-08-31
Abstract: PURPOSE:To realize dictionary retrieval in which dictionary retrieving time is shortened and in addition, a recognition rate is not lowered by using the major classification threshold values of two stages. CONSTITUTION:Data in a dictionary memory 3 and feature quantity data held in a feature quantity memory 2 are compared by every one dimension by a distance operator 4, and their difference is calculated as a distance value, and it is added and integrated by a distance adder 6, and simultaneously, the distance value is compared with a first major classification threshold value held in a first register 9 by a first comparator 10. When the distance value exceeds the first major classification threshold value, it is outputted from the comparator 10, and the count value of a counter 11 increases, and further, the count value of this counter 11 is compared with a second major classification threshold value held in a second register 12, and when it exceeds the second major classification threshold value, a finish signal is outputted from the comparator 13. Thus, the recognition rate can be prevented from becoming low while the dictionary retrieving time is shortened.

Title: Operational amplifier
Inventor: TAKAGI KATSUAKI
IPC: H03F3/45
Filed: 1983-11-21
Abstract: PURPOSE:To improve the through-rate by feeding back a node voltage at a differential stage to a bias voltage generating circuit in a differential operational amplifier. CONSTITUTION:A bias control circuit 1 consisting of the parallel connection with a P-channel MOS transistor (TR) M10 and an N-channel MOSTRM11 is inserted to the titled amplifier. The TRM10 goes to a low resistance when a node voltage V3 is lowred. On the other hand, the TRM11 becomes a low resistance when the voltage V3 is increased. Thus, the circuit 1 acts like a variable resistor becoming a low resistance when the voltage V3 is higher or lower than the operating point. As a result, the bias voltage V6 is low with V1 V2 and high when the difference between the potentials V1 and V2 is large, the current to the TRM5 is increased so as to increase the through-rate. Even if a large load is given to an output V0, since only the load with the own capacitor is given to an output V3, the response of the bias voltage is fast.

Title: Light emitting diode

Abstract: PURPOSE:To obtain a light emitting diode of high luminance, which can be mass-produced at a high yield and a low cost, by a method wherein the light emitting diode is provided with a first conductivity type second crystal layer formed of Ga1-yAlyAs and a second conductivity type third crystal layer formed of Ga1-zAlzAs formed on a second crystal layer, where the thickness of the third crystal layer is specified. CONSTITUTION:In a light emitting diode, the following layers are successively laminated on a primary face of a p-type GaAs substrate 10: a p-Ga1-xAlxAs layer (1>=x>0) of a first crystal layer 11 15-20mum in thickness; a p-Ga1-yAlyAs layer (1>y>=0, y<x) of a second crystal layer 12 0.5-2mum in thickness; and an n-Ga1-zAlzAs layer (1>=z>0, z>y) of a third crystal layer 55 mum in thickness. When the relation between the optical output of the light emitting diode and the thickness of an n-GaAlAs layer is checked, the following fact is found. When a thick n-GaAlAs layer is employed, a larger optical output can be obtained as compared with a thin layer, and moreover a thick n-GaAlAs layer can dispense with a complicate and expensive growth device required to control as As vapor pressure or the like, so that a light emitting diode provided with a thick n-GaAlAs layer is excellent in mass-productivity.

Title: Control device for engine
Inventor: OGAMI MUNEYUKI
IPC: F02D17/02
Filed: 1989-08-24
Abstract: PURPOSE:To restrain temporary power drop in an engine in which the number of operating cylinders can be changed following a prescribed condition by correcting the control value of a cylinder on combustion stroke directly before decreasing the number of cylinders at decreasing the number of operating cylinders so as to increase its output. CONSTITUTION:In a control unit U, a stopped cylinder is expediently changed utilizing a timer, and the control value used for temporary increase of engine output is instituted both of a fuel injection quantity and ignition timing. When a cylinder at zero injection timer value, namely the cylinder to be work is No. 4 cylinder C4 for example, the fuel injection quantity to the cylinder is remarkably decreased. To the No. 3 cylinder on combustion stroke directly before stopping the No. 4 cylinder, fuel injection quantity is increased. As an initial value of a timer is larger, the number of operating cylinders up to generation of succeeding no-working cylinder becomes many (small frequency of stop), and in this case, as the engine water temperature is lower, the initial value of the timer is made larger.

Title: Wiring of semiconductor integrated circuit element
Inventor: USHIO SHINTARO
IPC: H01L23/52
Filed: 1986-09-18
Abstract: PURPOSE:To suppress the formation of a hillock to be caused by heat treatment and to prevent a short circuit inside a wiring layer and between wiring layers in such a way that the whole of a wide wiring part is divided into narrow wiring parts. CONSTITUTION:A wiring structure is formed after a wiring part has been divided into more than one wiring parts 12, 13. A wiring part 12 with a width of 50 mum is composed of one 40 mum-wide wiring part and two wiring parts with a width of 50 mum each which are located on both sides of the 40 mum-wide wiring part, and the space between wiring parts is 1 mum each. The width and the number of wiring parts to be divided are decided arbitrarily. The width of wiring parts is decided by the maximum possible limit of the width which does not form a hillock and a lateral hillock 14 from the viewpoint of the film quality and the film thickness of an Al alloy wiring film. Regarding the dividing number, it is preferable that, because the total width of a wiring structure becomes wider, the number is reduced to a minimum by taking into consideration the upper limit of the width of divided wiring parts. The lateral hillock which protrudes from a wide wiring part in the center through heat treatment is formed only at a gap located at narrow wiring parts on both sides, and the lateral hillock does not exist as the whole wiring part. It is, therefore, possible to prevent a short circuit inside a wiring layer.

Title: Vertical joint structure
Inventor: OKA TOSHIHIRO
IPC: E04F13/08
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To prevent slipping-off from a panel strip of a facing cap. SOLUTION: An engaging section 3, in which a restraint piece and a fitting piece are formed in an approximately V-shape, is inserted into a fitting section 9, to which an approximately V-shaped fitting groove having width narrower than the V shape is formed of an external guide 10 and an internal guide piece. Accordingly, slippinf-off from the fitting section 9 of the engaging section 3 is prevented by elastic force in the compressive direction received from the fitting section 9 of the engaging section 3, and retaining force is increased. Even when a facing cap 1 receives large external force, the slipping-off of the facing cap 1 is made more difficult than the structure of a conventional vertical joint section.  Even when there are the repetition of the mounting and demounting of the facing cap 1 and inundation and expansion by freezing in a cold district, the slippinf-off of the facing cap 1 is made more difficult than the structure of the conventional vertical joint section.
