Title: Frame for electric bicycle
Inventor: SUZUKI MASAHIRO
IPC: B62K11/04
Filed: 1993-07-26
Abstract: PURPOSE:To prevent the lowering of strength of a down tube owing to the welding of brackets and position the connecting brackets for motor unit easily and accurately. CONSTITUTION:A motor unit 9 is connected to a down tube 2b with a down tube inserting type lug 5, a hanger lug 6, and connecting brackets 17 and 18 welded to the lugs 5 and 6 respectively. The hanger lug 6 is contacted to the rear end of the down tube 2b, and both lugs are connected through the down tube 2b. Since the both lugs are made as a jig for positioning practically, the connecting brackets 17 and 18 can be positioned easily and accurately. And since the connecting brackets 17 and 18 are not welded to the down tube 2b directly, the strength of the down tube 2b is not reduced even though the input calorie in the welding is high.

Title: Stroke converting method for dot pattern
Inventor: OKAZAKI TETSUO
IPC: G06K9/36
Filed: 1987-08-14
Abstract: PURPOSE:To eliminate the deformation of a reproduced character pattern caused by the smoothing processing by storing continuously plural same dots and converting the dot information into the stroke information when the reading direction is changed by >=90 deg. at a point where the reading dot is interrupted. CONSTITUTION:The searching direction is set to the lower side from the upper side and the searching is started. A dot is detected for the first time and defined as a starting dot and the dots A, B and C are successively set toward the starting dot C. The coordinate point is moved and the connecting direction between the turning point A and an adjacent dot to the point A is defined as a new searching direction when no dot exists at the next coordinate point 6 and at the point A and a dot exists at the adjacent point. In this case, three coordinate points are continuously stored in a memory 13 at the turning point as the intermediate dots when the angle is set at >=90 deg. between the old and new searching directions. Then the shift is carried out to the next coordinate point. Thus it is possible to avoid such a case where a corner part is mistakenly smoothed in a smoothing process when a character pattern is converted into the stroke information for reproduction.

Title: Pulse interval deciding circuit
Inventor: FUKUSHIMA TAKEO
IPC: H03K5/19
Filed: 1982-11-19
Abstract: PURPOSE:To detect the value of fluctuation in pulse intervals only by the operation of reversible counters by setting initially a desired deviation value of the pulse interval in advance for a pulse interval decision system equipped with two reversible counters. CONSTITUTION:The initial deviation value alpha of the pulse interval is inputted to the reversible counters 6 and 7 through a circuit 8. The counted value of the reversible counter 6 increases continuously on the basis of a value alpha as a basic point until a next input arrives at an input terminal 20 and the counted value of the reversible counter 7 decreases continuously on the basis of the value alpha as a basic point; when it enters an underflow state, a pulse from a C/B is inputted as a clock to a D-type FF4. Consequently, the output Q' of the D-type FF4 falls and is inputted to the up/down switching terminal U/D of the reversible counter 7, which then counts up. The counters 6 and 7 both count down by a next input to the input terminal 20, but when there is another signal appearing at the terminal 20 before the counter 7 enters the underflow state firstly and then the counter 6 enters the underflow state, it is found that the pulse intervals are within the range of the deviation value.
