Abstract: PROBLEM TO BE SOLVED: To improve leakage resistance and to certainly operate the battery in abnormal rising of inner pressure in the battery, by providing a notch in the outer surface of the upper part of an inner cylinder of a sealed body to form a thin portion, and positioning a welding line of a molding in the center of the thin portion. SOLUTION: A part of the outer surface of the upper half of an inner cylinder 11 is notched to form a thin portion 11a, and a welding line is positioned in the center 14 of the thin portion 11a. A gate of a die for molding a sealed body 10 is located at a position deviated from the center of the die, during molding, molten resin filled into the die is intruded from the gate to the opposite side of the central hole of the sealed body, the welding line occurs on the opposite side of the gate with spaced by the central hole, and furthermore, the center 14 of the thin portion 11a is further thinned. In this structure, when inner pressure of this battery abnormally rises, gas presses up a connecting portion 13 of the sealed body 10, and generates a clearance between the inner cylinder 11 and a carbon bar to go outward.  Therefore, a crack occurs in the thin portion 11a, gas goes through this crack part over the sealed body 10, and goes out of a gas exhausting hole in a positive electrode terminal plate.

Title: Substrate for packaging semiconductor element
Inventor: SAKURAI KAZUNORI
IPC: H01L23/50
Filed: 1987-05-22
Abstract: PURPOSE:To protect a substrate finger lead from disconnection even in the presence of an external force inflicted upon a substrate mounted with a semiconductor element or of stress within a sealing resin by a method wherein at least a portion of a finger lead corresponding to a semiconductor element electrode is designed to be wider than other portions of the finger lead. CONSTITUTION:At least a portion is designed to be larger than the other portions in a finger lead 2 to meet an electrode 6 of a semiconductor element 1. For example, a plurality of finger leads 2 built in a substrate to meet electrodes 6 of a semiconductor element 1 are subjected to etching for the formation of bumps 3 for connection to the electrodes 6. A bump 3 results from a process wherein a portion 1 is etched in thickness to approximately half the thickness of the finger lead 2. To mechanically strengthen the finger lead 2, the finger lead 2 is designed to be wider at the bump 3 and at a step 5. The finger lead 2 is designed, further, to form an arc at the widened portions. This allows stress that may concentrate on the bump 3 and step 5 to be dispersed.

Title: Four-wheel steering device
Inventor: UNOSAKI YOSHIHIDE
IPC: B62D6/00
Filed: 1986-05-29
Abstract: PURPOSE:To attempt a precise control at high speed as well as improvement of steering responsiveness at low speed by providing a partition number correction means which makes a digital partition number corresponding to an unit rear wheel steering angle vary in such a way as to be small at low speed, but be great at high speed. CONSTITUTION:In a low speed range, an angular width corresponding to one pulse as an input rear wheel steering angle information for a feedback control is four times as much as that in a high speed range. And a motor 21 is controlled in such a way that an actual rear wheel steering angle information thetar of a certain width to be detected corresponds with a target rear wheel steering angle deltar. Namely, if a steering angle deltar is out of an angular width means by the information thetar, the rotational direction of the motor 21 is determined for outputting a rotational output signal to a circuit 21b whereby the motor 21 is suspended by a hold signal as soon as the angle deltar falls within the angular width of the information thetar. By the afore-said constitution, the angular width of the information thetar is made wider as speed becomes lower, even if a rear wheel steering mechanism 10 somewhat overruns by inertia after the hold signal has been outputted, the steering angle deltar does not come out of the angular width of the information thetar whereby the information thetar is small at high speed for enabling a precise control to be exerted.

IPC: G06K9/62
Filed: 1983-07-13
Abstract: PURPOSE:To recognize a character at a high speed and with high stability by deciding plural dividing areas and having an overlap of the prescribed width between the adjacent dividing areas in case the division is given to an array of N-square sum of extracted distances for each side. CONSTITUTION:A feature extracting part 6 detects all changing points from white to black points. For the distance between said changing point and a point on a vertical side where the scan is started, the calculation is carried out with all changing points for the value obtained by N-squaring the value obtained by normalizing the length of a character frame in the direction X. Then the total sum of calculated values is stored to an array. A feature vector extracting part 7 uses eight types of arrays extracted at the part 6 and divides each array into M units, and the adjacent divided areas have an overlap with the prescribed vertical width of the character frame. The mean value is calculated for the elements of arrays to extract the feature vector. An identifying part 8 is described in the same style as said vector, calculates the distance from a standard mask and delivers the category name of the mask which produces the minimum value to a character name output 9.

Abstract: PURPOSE: To move the pickup smoothly towards the inner side of turntable by effectively canceling the outside force of pickup being used while playing back a disc record.  
     CONSTITUTION: When a disc record 5 rotates together with a turntable 10, the protrusion, 28 provided in tongue 27 of lifting member 25 abuts against the tapered part at the lower side of sector-shaped tongue 22 composed on a pickup mount 14. As a result, while the both bodies are abutting against each other elastically, an inside force exerts on the pickup 15, which effectively cancels the outside force of pickup 15 due to spring 21. Thereby, the pickup is allowed to move smoothly towards the inner side of turntable along the sound groove in a disc record. Thus, minimizing the damage to the disc and stylus, the characteristics of the entire system may be improved
