Title: Solenoid clutch
Inventor: TACHIBANA YOSHIAKI
IPC: H02K7/12
Filed: 1983-06-27
Abstract: PURPOSE:To locate a rotary shaft at two stable portions and rotate the shaft at the respective positions by selectively applying a current to a coil to move a movable portion by a reciprocal action between magnetic force generated from the coil and a permanent magnet. CONSTITUTION:In case of applying a current to a coil 8 to move a movable portion to B side, as the surface of the bearing 3 is magnetized to be of N pole by a permanent magnet 2, an exciting current of such a polarity is applied to the coil that A side of the movable portion 7 is N pole and B side is S pole. Thus, the surface of the bearing 5 is magnetized to be of N pole by the permanent magnet 4, so that repulsive force on A side and attraction force on B side are generated by the reciprocal action between the permanent magnets 2, 4, thereby to move the movable portion 7 in direction of an arrow B. On the other hand, a current opposite to the above is applied to move the movable portion 7 in direction of an arrow A. In either case, a rotary shaft can be moved up and down and turned round bearings 3, 5.

Title: Charge transfer type solid-state image pickup element
Inventor: KOIKE NORIO
IPC: H04N5/335
Filed: 1984-06-06
Abstract: PURPOSE:To improve the manufacturing yield and the performance by a method wherein the threshold voltage which a transfer gate has is risen up to a required value by reducing the channel width of the transfer gate to less than a specific value. CONSTITUTION:In Figs. (a) and (b), the numeral 7' represents the transfer gate, 2-1 an electrode constituting a vertical CCD, and a thick one-point chain line 20 the channel region of the vertical CCD2, the transfer gate region 7'-1, and a photo diode region 1'. When the channel width (w) constituting the transfer gate 7'-1 exceeds 8mum, the threshold value is constant with little variation. However, the reduction in channel width to less than 8mum shows a gradual increase in threshold voltage, and the reduction to less than 3mum shows a rapid increase. Therefore, when the channel width of the transfer gate is reduced more than a value close to 3mum, the threshold voltage rises by the narrow channel effect: it becomes possible to obtain a necessary threshold voltage not by ion implantation as conventional.

Title: Automatic fine-adjustment circuit
Inventor: FURUHATA MAKOTO
IPC: H03J7/04
Filed: 1977-09-26
Abstract: PURPOSE:To avoid the malfunction caused by the offset voltage by reversing the input application of the double-balance type switching circuit functioning as the phase amplitude detector circuit. CONSTITUTION:Phase amplitude detector circuit 1 performs an automatic control to obtain a coincidence between the oscillation frequency of the local oscillation circuit and the intermediate frequency. Then in case the offset voatage exists due to the voltage variance between the base and the emitter of differential paired transistors Q3-Q6, differential paired transistors Q3-6 of the upper side have no action for the period during which differential paired transistor Q1and Q2 of the lower side have operation owing to the difference of the frequency band between carrier filter 2 and tuning filter 3. Thus, the fine-adjustment circuit is locked with only the central frequency, avoiding the malfunction.

Title: Door driving controller
Inventor: SHIMADA JUNICHI
IPC: B60J5/06
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To reduce opening/closing operating physical force by manual operation while smoothing the automatic opening/closing of a door, by proving control means by which the tension of a flexible member is increased when the door is automatically opened and closed, and decreased when the door is opened and closed by manual operation. SOLUTION: When a control operating switch at the time manual opening/ closing, is not operated, an arm 21 is turned to the direction of an arrow A direction by a fist stopper 23A, and a pulley 22 is held in a position separated from a belt 15. Therefore, when a door is operated to be opened and closed by manual operation, opening/closing operating physical force is reduced by a part that tension may not be applied to the belt 15. When the operating switch is operated and the door is automatically opened and closed, the pulley 22 is pushed to the belt 15, and an appropriate tension is applied to the belt 15. The appropriate tension is applied to the belt 15, therefore a tensioner improves the good followup performance of the door, prevents occurrence of the pulsation of the door, and smooths automatic opening and closing.

Title: Branch extracting system
Inventor: GOTO HIROHISA
IPC: G06T7/60
Filed: 1988-05-12
Abstract: PURPOSE:To make a character recognizing device compact without needing complex post-processing by directly extracting the number of branches from a binarizing pattern, which is not formed to a core, and considering the shape of the binarizing pattern as well. CONSTITUTION:A data output device 10 for branch number determination reads the binarizing pattern and outputs data for branch number determination. A branch number extracting part 14 removes the branch number by a noise. A bending degree computing part 16 computes the ratio of sample points in two circular arcs to have the two points of a white point, a black point or a point, where the white and black is changed, as edge points to be continued on a circumference with an attention bit as a center when the branch number is 2. A branch number determining part 18 outputs the branch number from the branch number extracting part 14 when this ratio is a prescribed condition and outputs the branch number to be determined in advance when the ratio is the other condition. Thus, without needing the complex post-processing, the character recognizing device can be made compact.
